DESCRIPTION OF THE PREFERRED EMBODIMENT
While the present invention is susceptible of various modifications and alternative constructions, an embodiment is shown in the drawings and will herein be described in detail.
It should be understood however that it is not the intention to limit the invention to the particular form disclosed; but on the contrary, the invention
is to cover all modifications, equivalents and alternative constructions falling within the spirit and scope of the invention as expressed in the appended claims..
There is disclosed herein an electrical driving system which, . on. theory, will convert low voltage electric energy from a source such as an electric storage. battery to a high potential, high current energy pulse that is capable of developing a working force at the inductive output of the device that is more efficient than that which is capable of being developed directly from the energy source.
The improvement in efficiency is further enhanced by the, capability of the device to return that portion of the initial energy developed, and not used by the inductive load in the production of mechanical energy, to the same or second energy reservoir or source for use elsewhere, or for storage.
This system accomplishes the results stated above by harnessing the electrostatic" or "impulse" energy created by a high-intensity spark generated within a specially constructed electrical conversion switching element tube.
This element utilizes a low-voltage anode, a high-voltage anode, and one, or more "electrostatic or charge receiving, grids. These grids are of a physical size, and appropriately positioned, as to be compatible with the size of the tube, and therefore, directly related to the amount of energy to be anticipated when the device is operating.
The low-voltage anode may incorporate a resistive device to aid in controlling . the, amount of current drawn from the energy source.
This low-voltage anode is connected to the energy source through a mechanical commutator or a 'solid-state pulser that controls the timing and duration of the energy spark within: the element.
The high-voltage anode is connected to a high voltage potential developed by the associated circuits.
An energy discharge occurs within the element when the external control circuits permit. This short duration, high-voltage, high-current energy pulse is captured by the "electrostatic" grids within the tube, stored momentarily, then transferred to the inductive output load.
The increase in efficiency anticipated in converting the electrical energy to mechanical energy within the inductive load is attributed to the utilization of the most optimum timing in introducing the electrical energy to the load device, for the optimum period of time.
Further enhancement of energy conservation is accomplished by capturing a significant portion of the energy generated by the inductive load when the useful energy field is collapsing.
This energy is normally dissipated in load losses that are contrary to the desired energy utilization, and have here to fore been accepted because no suitable means had been developed to harness this energy and restore it to a suitable energy storage device.
The present invention is concerned with two concepts or characteristics.
The first of these characteristics is observed with the introduction of an energizing current through the inductor.
The inductor creates a contrary force (counter-electromotive force or CEMF) that opposes the energy introduced into the inductor.
This CEMF increases throughout the time the introduced energy is increasing.
In normal applications of an alternating-current to an inductive load for mechanical applications, the useful work of the inductor is accomplished prior to terminating the application of energy.
The excess energy applied is thereby wasted.
Previous attempts to provide energy inputs to an inductor of time durations limited to that period when the optimum transfer, of inductive energy to mechanical energy is occuring, have been limited by the ability of any such device to handle the high current required to optimize the energy transfer.
The second characteristic is observed when the energizing current is removed from the inductor.
As the current is decreased,the inductor 'generates an EMF that opposes the removal of current or, in other words, produces an energy source at the output of the inductor that simulates the original energy source, reduced by the actual energy removed from the circuit by the mechanical load. This "regenerated", or excess, energy has previously been lost due to a failure to provide a storage capability for this energy.
In this invention, a high-voltage, high-current, short duration energy pulse is applied to the inductive load by the conversion element.
This element makes possible the use of certain of that energy impressed within an arc across a spark-gap, without the resultant deterioration of circuit elements normally associated with high energy electrical arcs.
This invention also provides for capture of a certain portion of the energy induced by the high inductive kick produced by the abrupt withdrawal of the. introduced current.
This abrupt withdrawal, of current is attendant upon the termination of the stimulating arc.
The voltage spike so created is imposed upon a capacitor that couples the attendant current to a secondary energy storage device..
A novel, but not essential, circuit arrangement provides for switching the energy source and the energy storage device. This switching may be so arranged as to actuate automatically at predetermined times.
The switching may be at specified periods determined by experimentation with a particular device, or may be actuated by some control device that measures the relative energy content of the two energy reservoirs.
Referring now to FIG. 1, the system 10 will be described in additional detail.
The potential for the high-voltage anode, 12 of the conversion element 14 is developed across the capacitor 16. This voltage is produced by drawing a low current from a battery source 18 through the vibrator 20. The effect of the vibrator is to create a pulsating input to the transformer 22. The turns ratio of the transformer is chosen to optimize the voltage applied to a bridge-type rectifier 24. The output of the rectifier is then a series of high-voltage pulses of modest current.
When the available source is already of the high voltage, AC type, it may be coupled directly to the bridge-type rectifier.
By repetitious application of these output pulses from the bridge-type rectifier to the capacitor 16, a high-voltage, high-level charge is built up on the capacitor.
Control of the conversion switching element tube is maintained by a commutator 26
A series of contacts mounted radially about a shaft, or a solid-state switching device sensitive to time or other variable may be used for this control element.
A switching element tube type one-way energy path 28 is introduced between the commutator device and the conversion switching element tube to prevent high energy arcing at the commutator current path.
When the switching element tube is closed, current from the voltage source 18 is routed through a resistive element 30 and a low voltage anode 32
This causes a high energy discharge between the anodes within the conversion switching element tube 14.
The energy content of the high energy pulse is electrostatically coupled to the conversion grids 34 of the conversion element.
This electrostatic charge is applied through an output terminal 60 (FIG. 2) across the load inductance 36, inducing a strong electromagnetic field about the inductive load.
The intensity of this electromagnetic field is determined by the high electromotive potential developed upon the electrostatic, grids and the very short time duration required to develop the energy pulse.
If the inductive load is coupled magnetically to a mechanical load, a strong initial torque. is developed that may be efficiently utilized to produce. physical work.
Upon cessation of the energy pulse (arc) within the conversion switching element tube the inductive load is decoupled, allowing the electromagnetic field about the inductive load to collapse.
The collapse of this energy field induces within the inductive load a counter EME.
This counter EMP creates a high positive potential across a second capacitor which, in turn, is induced into the second energy storage device or battery 40 as a charging current.
The amount of charging current available to the battery 40 is dependent upon the initial conditions within the circuit at the time of discharge within the conversion switching element tube and the amount of mechanical energy consumed by the work load.
A spark-gap protection device 42 is included in the circuit to protect the inductive load and the rectifier elements from unduly large discharge currents.
Should the potentials within the circuit exceed predetermined values, fixed by the mechanical size and spacing of the elements within the protective device, the excess energy is dissipated (bypassed) by the protective device to the circuit common (electrical ground).
Diodes 44 and 46 bypass the excess overshoot, generated when the "Energy Conversion Switching Element Tube" is triggered. A switching element 48 allows either energy storage' source to be used as the primary energy source, while the other battery is used as the energy retrieval unit.
The switch facilitates interchanging the source and the retrieval, unit at optimum intervals to be determined by the utilization of the conversion switching element tube.
This switching may be accomplished manually or automatically, as determined by the choice of switching element from among a large variety readily available for the purpose.
FIGS. 2, 3, and 4 show the mechanical structure of the conversion switching element tube 14. An outer housing 50 may be of any insulative material such as glass. The anodes 12 and 22 and grids 34a and 34b are firmly secured by nonconductive spacer material 54, and 56. The resistive element 30 may be introduced into the low-voltage anode path to control the peak currents through the conversion switching element tube.
The resistive element may be of a piece or it may be built of one or more resistive elements to achieve the desired result.
The anode material may be identical for each anode, or may be of differing materials for each anode,as dictated by the most efficient utilization of the device, as determined by appropriate research at the time of production for the intended use.
The shape and spacing of the electrostatic grids, is also susceptible to variation with application (voltage, current, and energy requirements).
It is the contention of the inventor that by judicious mating of the elements of the conversion switching element tube, and the proper selection of the components of the circuit elements of the system, the desired theoretical results may be achieved.
It is the inventor's contention that this mating and selection process is well within the capabilities of intensive research and development technique.
Let it be stated here that substituting a source of electric alternating-current subject to the required current and/or voltage shaping and/or timing, either prior to being considered a primary energy source, or there after, should not be construed to change the described utilization or application of primary energy in any way.
Such energy conversion is readily achieved by any of a multitude of well established principles.
The preferred embodiment of this invention merely assumes optimum utilization and optimum benefit from this invention when used with portable energy devices similar in principle to the wet cell or dry-cell battery.
This invention proposes to utilize the energy con-mined in an internally generated high-voltage electric spike (energy pulse) to electrically energize an inductive load; this inductive load being then capable of converting the energy so supplied into a useful electrical or mechanical output.
In operation the high-voltage, short-duration electric spike is generated by discharging the capacitor 16 across the spark-gap in the conversion switching element tube.
The necessary high-voltage, potential is stored on the capacitor in incremental, additive steps from the bridge-type rectifier 24.
When the energy source is a direct-current electric energy storage device, such as the battery 12, the input to the bridge rectifier is provided by the voltage step-up transformer 22, that is in turn energized from the vibrator 20, or-solid-state chopper, or similar device, to properly drive the transformer and rectifier circuits.
When the energy source is an alternating-current switches 64 disconnect transformer 22, and the input to the bridge-type rectifier 24 is provided by the voltage step-up transformer 66, that is in turn energized from the vibrator 20, or solid-state chopper, or similar device to properly drive the transformer and rectifier circuits.
The repetitions output of the bridge rectifier incrementally increases the capacitor charge toward its maximum.
This charge is electrically connected directly to the high-voltage anode 12 of the conversion switching element tube.
When the low-voltage anode 32 is connected to a source of current, an arc is created in the spark-gap designated 62 of the conversion switching element tube equivalent to: the potential stored on the high-voltage anode, and the, current available from the low-voltage anode.
Because the duration of the arc is very short, the instantaneous voltage, and instantaneous current may both be very high.
The instantaneous peak apparent power is therefore, also very high. Within the conversion switching element tube, this energy is absorbed by the grids 34a and 34b mounted circumferentially about the interior of the tube.
Control of the energy spike within the conversion switching element tube is accomplished by a mechanical, or solid-state commutator, that closes the circuit path from the low-voltage anode to the current source at that moment when the delivery of energy to the output load is most-auspicious.
Any number of standard high-accuracy, variable setting devices are available for this purpose.
When control of the repetitive rate of the system's output .is required, it is accomplished by controlling the time of connection at the low-voltage anode.
Thus there can be provided an electrical driving system having a low-voltage source coupled to a vibrator, a transformer and a bridge-type rectifier to provide a high voltage pulsating signal to a first capacitor.
Where a high-voltage source- is otherwise available, it may be coupled direct to a bridge-type rectifier, causing a pulsating signal to a first capacitor.
The capacitor in turn is coupled so a high-voltage anode of an electrical conversion switching element tube.
The element also includes a low-voltage anode which in turn is connected to a voltage source by a commutator, -a switching element tube, and a variable resistor.
Mounted around the high-voltage anode is a charge receiving plate which in turn is coupled to an inductive load to transmit a high voltage discharge from the element to the load.
Also coupled to the load is a second capacitor for storing the back EMF created by the collapsing electrical field of the load when the current to the load is blocked.
The second capacitor in turn is coupled to the voltage source.

It has come to my attention that Edwin Gray when describing the workings of his device used a term called SPLITTING THE POSITVE to explain how his device worked.
I have been drawn to the attention of a simple circuit as above that apparently Jerry Decker has at his website for some time that may explain the resulting action . keelynet.com
I have tried the experiment myself.
I would suspect the battery sizes are not critcal but personally I am going to use three six volts batteries as they seem to be the easier to connect as above.
Two Batteries are connected in series that positive lead is connected to negative lead and so on. The third battery connection negative to negative.
So now that you have two leads free that come from the positive side of the third battery and a postive lead from the other two batteries as per circuit diagram.
These two leads are then connected to a small lamp as shown in circuit diagram.
I am going use a lamp globe rated at 6 volts.
The circuit is simple enough so other reading this may like to try this for themselves and let me know how you get on. My experiments with this circuit
