Abstract: A recoil simulator is disclosed which generates various predetermined mots and forces that may be imparted to training guns, weapons, and other devices, so as to give them realistic operational characteristics which they otherwise would not have.

Abstract: A notched/diagonally fed electric microstrip dipole antenna consisting of a hin electrically conducting, rectangular-shaped element formed on one surface of a dielectric substrate, the ground plane being on the opposite surface. The length of the element determines the resonant frequency. The feed point is in a notch located along the diagonal with respect to the antenna length and width, and the input impedance can be varied to match any source impedance by moving the feed point along the diagonal line of the antenna without affecting the radiation pattern. The antenna bandwidth increases with the width of the element and spacing between the element and ground plane. Singularly fed circular polarization is easily obtained with this antenna.

Abstract: A constant altitude auto pilot circuit samples an altitude electronically d produces error output voltages proportional to the changes in altitude which are used to command the control system of an aircraft. To set the device, the plane obtains the desired altitude whereafter the device is activated. A switch in parallel with an op-amp is closed to charge a capacitor to a voltage level proportional to the output of a transducer. When the switch is opened, all inputs to the op-amp become relative to the charge of the capacitor. Any variation is amplified by the op-amp. Additional inputs allow biasing the altitude signal up or down or introducing a damping signal for control loop stability.

Abstract: A complex pulse repetition frequency generator for producing a pulse repeion frequency (PRF) signal having programmable stagger intervals. The device consists of a clock for selecting one of a series of standard clock pulses which are used to increment a counter. A comparator compares the accumlated clock pulses with a stagger data output signal produced by a data memory source. When the outputs are equal, the comparator produces a PRF output pulse. Two data memory bands are provided; a random access memory in which stagger data can be programmed by a series of switches, and a preprogrammed read-only memory. Address counters are used with each memory unit and provide capability for addressing selected memory locations from the data memory sources. A pulse width generator allows the operator to vary the pulse width and utilizes an injection lock oscillator to prevent jitter whenever a standard clock pulse is used which is not an even multiple of a hundred nanoseconds.

Then, the gas-saturated water of one of said cylinders is mixed with that of the other, thereby causing the gases therein to be mixed wthin the mixed water. The resultant gaseous mixture is subsequently separated from said water mixture, dried, and stores as a mixture of hydrogen and oxygen gases.

Abstract: A programmable microwave modulator for controlling the amplitude of a micave signal versus time. A programmed driver generates a linear analog signal that has a predetermined amplitude pattern and time period. The linear analog signal from the programmable driver passes through a linearized current driver before inputting a PIN attenuator. The linearized current driver takes the antilogarithm of the linear analog signal, thus compensating for the logarithmic nonlinearity of the PIN attenuator. A radio frequency signal from a receiving antenna inputs the PIN attenuator and is attenuated as a function of the amplitude pattern of the linear analog signal. The PIN attenuator outputs the attenuated radio frequency signal.
