A suitable reaction motor has a combustion chamber in communication with the discharge nozzle by way of a relief valve, a compressible fuel tank pressurized by gases from the combustion chamber by way of a differential piston pump actuable by the combustion gases and controlled by a command operable, solenoid actuated valve, and means for initially heating and pressurizing the combustion chamber.

Abstract: A device for controlling the lag angle of optical fiber as it is wound on a obbin prior to the fiber wound bobbin being placed in a missile and payed out during flight on the missile. The device includes a laser light source which is projected into the groove between the turns of fiber being wound on the bobbin. A hemispherical detector receives the reflected laser light as it tracks the light between the grooves and any difference in the light intensity that is received by the detector is amplified and is used to speed up or slow down a reversible, variable speed motor which controls the winding of the fiber on the bobbin.

Abstract: A two piece thru-bulkhead initiator. A first member carried by a rocket mr encloses a pyrotechnic charge and a receptor charge. A second member enclosing a confined detonating fuse and a receptor charge is releasably secured to the first member. The mating surfaces between the two members must not contain air gaps.

Abstract: The pulsed gas supply consists of a cylindrical gas reservoir which conta a multiplicity of small release ports in a helical pattern and an inner cylindrical rotary valve which also contains a multiplicity of small release ports in the same helical pattern. The reservoir and valve constitute an integral unit which has the advantage of totally balanced forces on a single moving part. This allows for motion free of friction caused by the high pressures of the gas supply.

Abstract: A locking device for retaining a plurality of drawers in secured relation in a cabinet even while the cabinet is being transported and subjected to extreme vibrations. The device includes a rod carried in openings provided in upper and lower support brackets secured, respectively, to upper and lower surfaces of the cabinet. The rod is movable into and out of engagement with the drawers while remaining in the support bracket. The rod is provided with protrusions in the form of roll pins for retention of the rods in the brackets. The brackets are provided with grooves adjacent the openings to permit insertion of the protrusions on the rod therethrough. The roll pins extend beyond the openings in the brackets and are disposed for engagement with the lower surfaces thereof to prevent the rod from coming out of the brackets even under extreme vibrations.

Abstract: A retainer mechanism for releasably securing a kinetic energy penetrator to he forward end of a missile while the missile is stored, transported and subsequently fired at a target such as a tank. The retainer releases the penetrator in flight responsive to acceleration acting on the missile, to reduce drag on the penetrator in its travel to the target.

Abstract: A closed loop dynamic alignment fixture which has a pivot plate which is pted to have a rate gyro mounted thereon and a base which is adapted to be mounted on a rate table with means for automatically adjusting the pivot plate relative to the base plate and rate table to allow for the testing of the amount of misalignment of an input axis of the rate gyro that is mounted thereon to allow misalignment data to be gathered on high drift rate gyros.

Abstract: An add-on ballast assembly for adding on to a missile in the field in a fle manner. The ballast is added in the unused hollow center of bobbins secured in the aft end of the missile. The bobbins have guidance wires wound therearound to be dispensed during flight. The addition of the ballast changes the center of gravity of the missile.

Abstract: A unique code device for use with explosive devices. A stepping motor is vided with a shaft for rotation a predetermined number of times for arming the explosive device. Magnetic damping (braking) means is provided to constrain rotation of the shaft.

Abstract: Apparatus for removal of connectors from printed circuit boards. The connors have spring-lock type of conductor pins therein which secure the connectors to the printed circuit board in substantially permanent relation and if some conductor pins were to become defective the whole printed circuit board would be thrown away. The device of the present invention is disposed for removal of the connectors from the printed circuit board without causing damage to the board.

Abstract: A sled test facility employing a tubular shaped track for testing missile d aircraft guidance and control systems. A blockhouse is at one end of the track and a recovery station at the other end. A compressor in the blockhouse and recovery station controls the g-profile of the sled as the sled moves in a cushion of air in the tubular track. Instrumentation and controls are provided in the blockhouse and recovering station.

The device is pneumatically operated from a high pressure gas supply and includes a cutter assembly which extracts the sample. The cutter assembly is movable to different positions for successive sampling operations.

Abstract: A device for controlling the twist associated with optical fiber being wo on a bobbin is disclosed. Signal transmission analysis in fibers wound on bobbins require techniques not normally encountered when considering long straight fibers. Signal loss on a fiber cable payout assembly is mainly due to small bends in the fiber at crossover positions and in the transmission regions where the winding travel changes directions. The signal attenuation in a length of optical fiber is also known to be a function of the amount of twist in the fiber both in the wound and payed out states. This invention allows the amount of twist of the optical fiber to be precisely controlled from zero to full (360 degrees twist per turn of the bobbin) twist to provide optimum signal transmission for both the wound and payed out states.
