Abstract: A rotary cam load positioning apparatus has a base, a bottom cam rotatably mounted on the base, and a top cam rotatably mounted on the bottom cam. The rotary cams have cylindrical wedge-shaped configurations with respective upper and lower surfaces disposed in inclined relation to one another. Thus, rotation of the top cam relative to the bottom cam will produce a change in the elevation position of a load supported on the upper surface of the top cam relative to the base, whereas rotation of both top and bottom cams together will produce a change in the azimuth position of the load supported on the upper surface of the top cam relative to the base.

Abstract: An optical rotary joint includes a rotating input lens assembly which emits a ray set from a focal point to illuminate a cylindrical reflector. Rays reflected from the cylindrical reflector pass through another focal point and are reflected from the cylindrical reflector to pass through still another focal point. This reflection and focusing continues until the ray paths are incident to a window in the cylindrical reflector and exit. Exiting rays are focused by a lens arrangement which focuses the rays to an output optical fiber.

Abstract: A vacuum blanket for holding a sensitive sheet of material in precise registration with a film master against a rigid transparent plate includes a blanket of thin, flexible material having at least one vacuum port therein and an inside face opposing the rigid plate and adapted for biasing the sensitive sheet and film master toward the rigid plate in precise registration with one another. A flexible perimeter seal is provided around the edges of the blanket for sealing off a vacuum chamber established between the blanket and the plate when air is withdrawn through the vacuum port. A bladder of thin, flexible sheet material is secured to the outer surface of the blanket with a plurality of spaced apart seams forming a plurality of separate, inflatable air chambers on the outside surface of the blanket.

Abstract: A safety, locking, pull ring for a munition which must be deformed and simultaneously rotated from a protecting locking recess and which must then be rotated 180 degrees from the recessed position in order to free one end of a pivotably attached bar. The bar must then be rotated 180 degrees, using the ring as a handle, to expose both a safety wire which must be removed to arm the munition, and expose an indicator light, which indicates the safe or unsafe condition of the munition, and finally to crush an ampule to release electrolyte to energize a battery which powers the munition electronic circuitry.

Abstract: This portable munition system has multiple modes of operation with the sensor inputs, output actuator circuits, and timing requirements determined by the control electronics. A self-check is performed initially before the munition can be armed. An indicator light driven by the electronics circuitry provides status information to the operator. The warhead can be aimed with integral sights.

The ATE is useable for testing a variety of electrical equipment type units each of which is referred to with relation to said ATE as a unit under test (UUT). The source program involves (1) having a test engineer, who designs the individual tests, enter the tests graphically at a work station, (2) verifying the match between the entered test design, the ATE capabilities and the UUT description, and (3) having an automatic way of generating a test program for a test program set from the stored semantic content of the graphically entered test design.

Abstract: A wet-mateable fiber optic connector includes mateable and demateable plug and receptacle parts having opposite end housings. The housings mount inner sleeves which interfit with one another when the connector parts are assembled together. Guide and latch fingers attached to the receptacle part facilitate interfitting of the sleeves together and latching and retaining the connector parts in mated condition.

The wand structures are mounted at inner ends to centering and sealing members in the respective inner sleeves. When the parts are mated together, one of the centering and sealing members mounts in axially aligned and a butting relation respective inner ends of the wand structures and positions in axially aligned and optically coupled relation the respective ends of the optical fiber end portions extending through the wand structures.

Abstract: A raster deflection signal generator that generates deflection signals in accordance with sweep control signals provided by a programmable timing generator. The programmable timing generator stores digital signals representative of the desired sweep control signals so as to tailor the sweep timing to the input video channel. The digital sweep control signals are synchronized to the input video channel by locking a horizontal sync pulse generated by the programmable timimg generator to the horizontal sync pulse of the video input channel by a phase locked loop. Each deflection sweep is compared to a threshold voltage representative of screen center to provide a duty cycle signal in accordance with drift of the TV image from screen center. The duty cycle signal is filtered and sampled and fed back to the sweep generator so as to maintain the deflection sweeps properly centered.

Abstract: A safety apparatus to safe or to arm and fire a munition, utilizes a rotor containing an aligned adjacent firing pin and detonator in holes extending completely through the rotor perpendicular to the axis. A first explosively powered piston actuator, when fired, will unlock the rotor and enable a second explosively powered piston actuator, when fired, to rotate the rotor to align the detonator with an explosive charge and to cause a firing pin to fire the detonator. The detonator will fire a transfer lead which, in turn, will fire the main charge. As assembled, a third explosively powered piston actuator is aligned with the detonator and, when fired, will cause the detonator to explode and translate the rotor with part of the axis extending out of the munition where it is held in this position to indicate a safe condition.

Abstract: Transponder reply rate limiting employing a circular memory queue to store the times of prior responses up to the limits of circular memory queue capacity. Separate circular memory queues contain the times of (1) long replies, and both (2) long or short replies. Each circular memory queue has a pointer and several offset indicators which are spaced from the pointer to the time entry positions at predetermined intervals according to corresponding preestablished criteria. After each transponder reply, the time of the reply is entered in the circular memory queue at a next pointer location. Eartimes, i.e., earliest allowable response times, are repeatedly determined and compared to time elapsed from a selected reference time. When the current time exceeds the eartime, for a given inquiry signal, a response signal is generated by the transponder electronics and is transmitted to the inquiring ground station. Eartimes are based upon predetermined criteria of allowable response rates in selected time periods.

Abstract: An angular position encoder utilizes Moire fringes formed by illuminating regions of coded images arranged circumferentially on wheels rotatable in accordance with angles to be encoded. Movement of the Moire fringes from a reference position is detected and used to determine the angular movement. All non-rotating movements of the coded wheel are compensated by the encoding process and do not effect the output.
