Abstract: Improved optical holographic apparatuses are disclosed for making white light viewable rainbow holograms in one step utilizing concave mirror optics. On-axis and off-axis configurations are presented for holography of real objects and for reduced image holography of a real image projection from a laser transmission hologram. An optical apparatus and curved recording device are devised to reduce and/or eliminate certain aberrations introudced by the concave mirror. To yield a wide holographic field of view at low cost, small diameter mirrors are employed in two alternative devices for replacing a single concave mirror in the various embodiments. Two methods are then presented to obtain reduced image size one-step rainbow holograms from a full size object or holographic image.

Abstract: A fluid delivery monitoring and control apparatus for use in a medication infusion system is designed for use with a disposable fluid pathway that incorporates a sterile cassette containing pumping elements and sensor interfaces. The apparatus comprises a multi-segment drive mechanism, controller, and monitoring system. Fluid pumping is accomplished by controlling DC motors in the drive mechanism, each of which is coupled to two valves and a reciprocating piston for an individual pumping channel in the cassette. The motor is geared down to provide an appropriate maximum speed and torque. A cam sequentially actuates an inlet valve, piston, and an outlet valve in the cassette. A range of fluid delivery rates is achieved by periodically sending pulses to the motor. The output flow rate of the pump is maintained by a digital feedback controller which uses closed-loop feedback control to provide accurate regulation.

Abstract: A true mass fuel gaging system for aircraft utilizing multiplexing of tank unit measurements in or adjacent a fuel tank for improved accuracy and fault isolation. The system provides dual equipment channels for redundancy throughout all data processing portions of the system and also uses extensive built-in testing (BIT) routines so that upon detection of a fault an alternative channel can be switched into use. Detected fault locations are displayed in the cockpit with the fuel quantity displays. The system also provides displays of center of gravity measurements derived from fuel mass and location.

Abstract: A miniaturized vacuum generator is powered by pressurized air, such as is commonly available in shop air lines. The generator includes a transducer coupled to the pressurized air line and utilizing the venturi principle to develope a vacuum at a vacuum port to which a vacuum hose may be coupled. This may be used in cleaning circuit boards and small electronic assemblies to pick off bits of solder, filings and other debris and contaiminants which more conventional vacuum cleaners do not effectively remove. The apparatus includes an in-line filter for collecting such debris and contaiminants and preventing them from being blown about by the exhaust. The apparatus may also be used as a pickup device for microchips and other miniature complements on an electronic assembly at a production line. Other uses of the device may be in the jewelry repair field where the debris to be picked up often contains dust and filings of precious metal and, occasionally, lost gemstones.

Abstract: A modular building design includes a building frame construction of superior strength and rigidity with roof, floor and wall panels designed for insertion in modular frame openings. The design permits complete fabrication of all shell components in a central manufacturing facility and is such that the various elements may be shipped or stored in an essentially flat package configuration. The only tools required for erection on the building site are conventional wrenches and nut drivers. The need for skilled workmen at the site is virtually eliminated.

Abstract: An inference machine is described which comprises an adaptive polynomial network with the capability of implicitly inferring missing input information contained in time-dependent signals. The proposed network has wide applicability and is characterized by its ability to produce outputs within specified degrees of accuracy when, for example, only four out of ten input signals are available to the network. Specific applications include terminal guidance of a tactical missile when critical signals may be denied. A generic implementation is schematically illustrated.

Abstract: A rotary optical coupler is capable of providing continuous, bi-directional, multiple optical links between two objects in relative rotation to each other. The coupler comprises two parts, a rotor and a stator, both of which are constructed similarly. Each part has circular tracks of selectively angled reflectors which project light beams to corresponding receptors during relative rotation with the other part. In this manner are the optical links achieved.

Abstract: A light which may be mounted in a corner is disclosed which utilizes a light cover having a unique configuration specifically designed to be quickly and conveniently mounted in a corner or like location, with any of several lighting arrangements being located in the corner under the light cover. The light cover is made of translucent material which will disseminate the light from a light source contained under the light cover, which consists of an essentially rectangular segment which is bent along one diagonal to form a configuration which will fit entirely in a corner. Either a fluorescent tube or one or more incandescent light bulbs may be used as the light source, which in the preferred embodiment is mounted in a socket apparatus which is installed in the corner on one or both of the surfaces forming the corner, thereby centrally locating the light source with respect to the light cover which is anchored to the wall or ceiling.

Abstract: An actuation system for controlling the steerable nozzle of a missile or like vehicle. The system comprises two essentially identical actuators mounted along a plane generally transverse to the missile axis and oriented orthogonally relative to each other about the missile axis for pivoting the nozzle through mutually orthogonal axes, thereby achieving omni-directional steering. Each actuator includes an elongated yoke plate extending about the nozzle for applying steering forces against a yoke seat circumferentially mounted on the nozzle. Each yoke plate is pivotably mounted at one end and driven laterally at the other end by a gearing mechanism affixed to the nozzle skin.

Abstract: An apparatus and method are disclosed for holding a generally cylindrical workpiece for honing or otherwise machining an internal bore. The workpiece is held by a gripping surface over most of the innermost turn of a spirally wound spring and coil. The workpiece is grasped circumferentially over its outer surface without excess contact pressure at any particular point. A tendency of the machining operation to rotate the workpiece serves to secure the workpiece more tightly in position by tightening the outer turns of the spring band coil. A rotatable tensioning member acts under the influence of a biasing spring to decrease the diameter of the innermost turn of the spring band coil to bring the gripping surface into contact with the workpiece. A method for adapting the work-holding apparatus to smaller or inrregularly shaped workpieces consists of molding an annular piece around the workpiece.

Abstract: A work-holding implement for use in honing or otherwise machining the inner surface of a bore in a workpiece comprises a torsion-carrying spring band coil mounted at one end of a handle. Most of the inwardly exposed surface of the innermost turn of the coil is a gripping surface, while the remaining turns in the coil have smooth bearing surfaces. A workpiece is gripped by the innermost turn, and as an interior bore in the workpiece is being honed or otherwise machined, rotational torques exerted on the workpiece by the machine tool cause the coil to become more tightly wound around the workpiece. As the workpiece is being worked on, the tightened coil bears against a planar segment of the spring band forming part of the implement and deforms it into a curved surface conforming to the workpiece surface over which contact is made.

Abstract: A communication system particularly adapted for use in an aircraft collision avoidance system wherein the transmitted portions of messages changed between aircraft consist of pulses or pairs of pulses at the beginning and end of a message. The data or information content of a message is defined by the time duration between start and end pulses, an interval during which the sender's transmitter is off. Thus the media is clear for other aircraft to use during the major portion of any message, thereby greatly increasing the number of aircraft which can be accommodated by the system without overloading the communication medium. The system provides for determining the presence of other aircraft in the near vicinity which may be a collision threat and for sending intent messages to threat aircraft to assist in collision avoidance.

In one embodiment, the device is of thermoformed plastic and may include a flexible front wall in the microscope slide member, overlaid by a removable flexible support strip attached thereto by spaced ribs of adhesive so that such front wall ripples and flexes during removal of the strip to uniformly mix sediment collected in the cavity.

Abstract: A waterbed contains a plurality of pliant plastic cylindrical containers, closed at both ends by end caps, one of which has a re-closable fill opening. In the preferred embodiment, the containers are fabricated by first extruding a polymer mixture into a tubular configuration and cutting to the desired length. One end of the tubing is framed by a support member in such a way that a portion of the end of the tube folds over the support member. The support member is constructed in a manner so that it may be disassembled into two sections. A flat end piece section is then placed over the assembly and the thus-formed end assembly is positioned within a support fixture such that the sealing end surface of the assembly is supported on the upper face of the support fixture. The fixture is then moved to a sealing area where an induction heater generates sufficient heat to heat seal the flat end piece to the end of the tubular member.

Abstract: An integrated motor pump unit for use as a hydraulic fluid pressure source at a remote location incorporates a pump rotor affixed in the center of a motor rotor. The motor/pump rotor assembly spins on a fixed shaft in a combination providing both radial journal and axial thrust bearings. The stationary shaft assembly incorporates a piston drive mechanism which is angled, relative to the shaft axis, so that reciprocal movement of the pistons is developed as they rotate about the axis. The fixed rotor shaft is axially adjustable to control the end clearance between the pistons and cam surfaces, and contains fluid flow galleries to the journal and thrust bearings. A magnetically permeable sleeve is mounted between the motor stator and rotor to seal the hydraulic fluid within the rotor space, thereby maintaining the stator windings and associated electronic circuitry in a dry environment.
