Abstract: An unguided projectile achieves a flat trajectory by generating gravity-ctering aerodynamic lift. The lifting device is stabilized in roll by a displacement-type gyroscope which is mounted directly to the lifting section of the projectile. Both the lifting device and the gyroscope are mounted on bearings to permit free rotation of the projectile body relative to the roll-stabilized lifting section. Lift vector orientation is maintained irrespective of projectile roll.

Abstract: A lifting and stowage system for lifting and stowing containers within a ited magazine area. The system provides a sway bracing feature during lifting which also functions as a stowage member when completely assembled. The system also includes a pair of guide rails attached vertically to the bulkhead and a carriage that travels up and down the guide rails. A strongback is attached to the carriage and is located over the container that is positioned by a forklift. The system employs a lifting mechanism consisting of a power source, a pulley and cable system, a snatch block which attaches to the carriage, a stowage system which restrains the stack of containers in all directions and deceleration buffers. In operation, the strongback is attached to the container and the snatch block is attached to the carriage. The container is lifted to allow vertical clearance for the next container. The lower container is positioned by a forklift and the upper container is lowered onto it.

Abstract: A loss-of-phase-lock indicator circuit is described which detects an out-limit voltage, whether steady or transitory. A pair of comparators, one for the high limit and the other for the low limit, are inserted in series between the tuning voltage and the sweep feedback amplifier, and are dc-coupled to the peak detector in the failure circuit. Additionally, a "dither" voltage is added in series with the phase detector, which ac voltage is large enough to swing the tuning voltage between limits at the loop amplifier output, but small enough to produce little effect on the output during phase lock.

The coils, connecting conductors, and framework are adapted to be spread open and closed around the member to be inspected.

Abstract: A method for steering solid propellant ballistic vehicles during powered flight which eliminates the requirement for cutoff control by allowing simultaneous fuel depletion and velocity-to-be-gained, V.sub.G, nulling. The vehicle booster is steered along a velocity trajectory of length equal to the remaining velocity capability, V.sub.CAP, which results in a fuel-inefficient trajectory. The trajectory is divided basically into three phases--an exit phase, a fuel-depletion guidance (FDG) phase and a short phase of constant attitude thrusting just prior to final stage burnout. For the exit phase the launch azimuth and the pitch-over magnitude can be varied from their usual fuel-efficient values. During fuel-depletion guidance the additional degree of freedom is the angle, .theta., between V.sub.G and the desired thrust direction, U.sub.S, where: ##EQU1## a.sub.T being the sensed acceleration vector.

Abstract: Information about the plasma density profile in an aerodynamic flow field of plasma adjacent a supersonic space vehicle or test model is provided by a flush mountable plasma density profile probe device having at least three striplines embedded in and separated by a dielectric support member from a conducting ground plane therebelow. In operation, the device is affixed flush and conformally to the surface of the space vehicle or test model. The plasma density profile is determined from a plot of data points derived from sequential measurements, in the plasma flow field environment, of the conduction between a driven stripline and parallel flush embedded additional striplines in the order of the nearest stripline to the furtherest stripline from the driven stripline. Standard formulas can be applied to determine the data points.

Abstract: Apparatus for mixing viscous, curable liquid materials in which the compots to be mixed are fed at high pressure (up to 5000 psi) into the central longitudinal chamber of a mixing head. The inlet ducts are on opposing sides of the chamber and displaced longitudinally so that there is no mixing of the components in the upstream end of the chamber where the drive shaft enters the mixing head. The two components are forced from the chamber through rotating apertures into a rotating inner tube (rotating at up to 500 RPM). The end of the rotating inner tube is closed so that the high pressure forces the material through a multiplicity of apertures in the wall of the tube. The rotating tube is enclosed in a concentric stationary tube having a multiplicity of apertures in its walls. The material is forced through the second group of apertures into an annular outer chamber which leads to the output of the mixer.

Abstract: Subharmonics of a data waveform are generated for the purpose of reducing ta bandwidth prior to transmission. Input data waveform is phase split and the antiphased output signals are fed to a rectifier. The rectification of antiphased signals creates two pulsating voltage with opposite polarity. The pulsating voltages are alternately switched by a chopper to provide a sinusoidal signal. The sinusoidal signal is filtered to average the energy of the pulsating voltage to provide a smooth waveform of one-half the frequency of the input data waveform.

Abstract: A crystal oscillator that is temperature compensated by digitally substrang a correction frequency from the running frequency of the crystal oscillator to provide the required operating frequency. The correction frequency is generated by a digital frequency synthesizer circuit which is controlled by the output of a programmable read-only memory which has been programmed to generate the required correction frequency for each temperature code over the operating temperature range. The temperature code is generated by gating a digital counter with the output of a monostable multivibrator which utilizes a thermistor to make its gate interval proportional to temperature.

Abstract: A system for transferring cargo at sea by helicopter includes an automatily activated self inflatable apparatus for reducing the velocity of the cargo if jettisoned or inadvertently dropped into the sea and for keeping the cargo afloat until retrieval may be accomplished. The cargo is lifted by a support sling attachable to a helicopter suspension cargo hook and simultaneously connected to a second sling in parallel to the helicopter through the rapidly deployable retardation and floatation device. Release of the support sling causes the cargo to drop and initiate deployment and inflation of the ribs of the parachute thereby retarding the cargo's descend and providing buoyancy for its floatation.

Abstract: A system for remotely controlled focusing of a reconnaisance camera instad on an aircraft. The camera can be focused to any of a plurality of pre-selected focused position, each position having a unique corresponding binary coded decimal designator generated from a position correlated switch. When a change in focus is selected by depression of a push button switch, the resulting binary coded decimal designator for the desired focus position is added to the binary coded decimal designator from the optical switch. Differences between the two designators will cause a scanner to rotate and scan all optical switches, while simultaneously a gear mechanism adjusts the camera lens focus position to the position corresponding to that for the switch scan at that increment of time. When the scanner locates the activated switch whose binary coded decimal designator is the same as the designator of the selected pushbutton, scanning and focusing adjustments are halted.
