| Number | Title | Issue Date |
| 4140917 | Fast risetime spiral pulse generator A vector inversion stacked stripline pulse generator adapted for single sch initiation consisting of a relatively long laminated assembly of alternate layers of dielectric and metallization wound on a non-magnetic cylindrical form with the metallization ... | 02/20/1979 |
| 4109192 | Low power reactive drive circuit for capacitive loads A circuit for driving capacitive loads which utilizes the temporary storage characteristics of an inductor in a resonant LC configuration to force current to flow from a low potential location to a high potential location at selected switching times. The ... | 08/22/1978 |
| 4109216 | Microwave generator An active radar transmitter is disclosed having both long pulse and short lse operational modes. The transmitter is configured to switch between the operational modes with a minimum of circuitry to permit a single radar system to be used for long-range se... | 08/22/1978 |
| 4092559 | Controlled discharger Disclosure is made of a low-inductance (L = 0.5 to 3 mH) controlled discharger for commutating megampere currents, having a maximum controllability range with respect to voltage, and a small operation lag. The low inductance and high transmitting capacity... | 05/30/1978 |
| 4079265 | Apparatus for producing high voltage pulses by capacitor discharge For energizing an X-ray tube in a diagnostic X-ray unit, a group of capacitors are each charged up to a voltage lower than that required by the X-ray tube, and then the capacitors are discharged one after another through the primary winding of a voltage s... | 03/14/1978 |
| 4075504 | Power supply apparatus Apparatus for supplying electrical power to d.c. loads such as lights, pumps and the like in a recreational vehicle. A converter is connected to an a.c. power source external to the vehicle to convert a.c. power therefrom to d.c. power and to supply the d... | 02/21/1978 |
| 4047050 | Calibrating impulse generator for an impulse-shaping element A calibrating impulse generator which is connectable to the input of a signal-shaping element, the latter of which reshapes the input signal in comformance with the function ##EQU1## The calibrating impulse generator is constructed, whereby a calibra... | 09/06/1977 |
| 4045719 | Regulated voltage source A circuit for deriving an output voltage of a first polarity from a signal source which produces a voltage whose value fluctuates between a reference level and a level opposite in polarity to said output voltage. Disclosed are provisions for maintaining t... | 08/30/1977 |
| 4017705 | Impulse current generator for electroerosion machining of metals An inverter generates a series of pulses which are differentiated by the coupling capacitors and rectified by the rectifier circuit to produce a series of short pulses which are all directed in the same direction or have the same polarity and are suitable... | 04/12/1977 |
| 4011463 | High voltage pulse generator An improved high-voltage pulse generator has been provided which is especially useful in ultrasonic testing of rock core samples. An N number of capacitors are charged in parallel to V volts and at the proper instance are coupled in series to produce a hi... | 03/08/1977 |
| 3989998 | Wide range pulse generator A pulse generator for generating pulses over a wide range without changing scales is disclosed. The pulse generator is capable of generating pulses in the range from 0.5 Hz to greater than 2 MHz in one continuous range. The wide range of operation is achi... | 11/02/1976 |
| 3931528 | Pulse generator for reactive loads A pulse generator adapted for providing electrical pulses to a reactive load circuit.
