Abstract: A geometrically optimized precombustion chamber 12 for a diesel or stratified charge engine is provided which limits the maximum gas temperature through transonic and/or supersonic flow to prevent the production of nitrous oxides and is defined in accordance with the following equation: ##EQU1##

Abstract: A family of gun propellants formulated with polyglycidyl azide polymer (GAP) in conjunction with nitrocellulose (NC) to provide reduced flame temperatures while providing high mass impetus.

Abstract: A method and apparatus for thermal storage having a movable manifold which discharges thermal transfer fluid to trickle through a particulate solid thermal storage medium to be collected for distribution or recirculation in a manner such as to establish a vertical thermocline within said thermal storage medium, said thermocline being movable horizontally with said manifold.

Abstract: A solid propellant gas generator based upon dialkali tetranitroethane salts which produces high electron densities for magnetohydrodynamic (MHD) applications.

Abstract: An energetic binder comprises a hydroxy-terminated aliphatic polymer having pendant alkyl azide groups and method for producing same.

Abstract: A solid propellant gas generator comprising alkali chlorides, potassium fluorochlorinate, and aluminum which produces pure chlorinefluoride gas in the absence of other gaseous products.

Abstract: An infrared image is formed on the surface of a light-sensitive silicon position sensor having four outer electrodes equally spaced around the periphery of the sensor and a central electrode. A bias voltage is applied between the outer electrodes and the central electrode. Changes in current at the central electrode is used to modulate the intensity of a CRO beam. A light beam is used to scan the surface of the sensor in a fixed pattern and the CRO beam is scanned in synchronism with the light beam. Thermal variations produced by the IR image modulate the CRO beam, producing a visual image on the CRO screen of the IR image formed on the sensor.

Abstract: A liquid rocket propulsion system utilizing vehicle spin forces and/or propellant tank pressure to charge a specific amount of propellant through a differential area piston to create high chamber pressure.

Abstract: A variable threshold detecting circuit for use with radar signals where a given target will appear with the same intensity on the screen whether the target is nearby or far away. The 1/R.sup.4 decrease in amplitude of the returned radar signal is compensated for by discharging an integrating circuit and using the output voltage of the integrating circuit as the threshold to a threshold detector for passing only the radar signals exceeding the threshold.

Abstract: Apparatus for detecting a serial binary number includes a flip-flop connected to receive the words among which the word to be detected is contained at an input, and connected to receive the complement of the word to be detected at a reset terminal. The flip-flop operates to present a first output state when the word to be detected is applied to its input and a second output state when another word is applied to its input. A second flip-flop is connected to receive the output from the first flip-flop and is clocked by a signal to test the output state of the first flip-flop at the termination of each word applied to its input. The output of the second flip-flop is, therefore, indicative of the presence of the word to be detected at the input of the first flip-flop.

Abstract: Method and apparatus for automatically adjusting the resolution of a CWFM radio altimeter includes a counter for counting a signal produced by the altimeter having a period relatable to the altitude desired to be measured. Another counter counts the number of pulses of a time reference signal occurring over a predetermined number of periods of the altitude related signal. The number of periods of the altitude related signal over which the time-reference-signal pulses are counted is automatically determined by a circuit responsive to the fullness of the time-reference-signal pulse counter to produce a signal after the counter has reached a predetermined count. The next occurring multiple of the altitude related signal is then determined, and the number of time-reference-signal pulses then counted is divided by the number of the multiple found.
