Abstract: An illumination system for a vanity or the like in which a flat mirror mounted on a wall extends vertically from the vanity counter to the ceiling of a room. A recessed light source mounted in an enclosure is in juxtaposition with the mirror at the wall-to-ceiling junction over the vanity counter. An assembly of low voltage Xenon filled strip lights extends laterally within the enclosure to illuminate an arcuate reflector and is concealed from direct view by a horizontal portion of the enclosure. The enclosure has a downward facing aperture elongated according to the width of the mirror at the interface of the arcuate reflector with the mirror top edge. The mirror, light source and reflector cooperate to provide optimum vertical and horizontal plane illumination at the vanity counter and beyond.

Abstract: A "U-shaped" rigid stirrup member having a base and two legs extending from the base to the open ends of the "U" is mounted to the transom of a water craft symmetrically about the propulsion jet outlet. The mountings at the craft transom hinge the stirrup to facilitate the positioning of the "U" in a downward direction to act as a stirrup for boarding the craft and upward out of the way of the jet outlet and the water surface. A torsion spring at least at one of the hinge points automatically positions the stirrup upward after the craft is boarded but is easily overcome by hand to position the stirrup downward for boarding.

Abstract: An elongated, lighted message and clearance lighting assembly for mounting into the conventional generally horizontal indentation adjacent the roof line of a cargo vehicle container body. A pair of elongated fiber-optic cables are individually encased in a correspondingly elongated enclosure to illuminate the interior of said enclosure and pass light through an outward translucent face of the enclosure to present a graphic message provided on a translucent strip inside the enclosure. The fiber-optic cables are constructed to propagate light flux longitudinally and also radially outward. A portion of the translucent face of the enclosure may be colored appropriately to provide the legally required clearance lighting function.

Abstract: A power recovery speed control apparatus for use in a system driven by a substantially constant-speed power source driving a turbine type water pump. The system includes a hydromechanical trimmer device controlled by pump output pressure to modify the turbine pump speed over a relatively small range as a function of pump output pressure. In series between the power source output shaft and the turbine pump drive shaft is a mechanical differential gear assembly having input, output and differential (speed difference) shafts. A fixed displacement hydrostatic transmission unit (pump) extracts a fraction of the source power at the differential shaft and applies it through hydraulic feed lines to a variable displacement hydrostatic transmission unit operated as a hydraulic motor. The hydraulic motor unit has its displacement controlled by a pump output pressure sensor and its output torque is introduced into the power train at the power source output or alternatively, at the turbine pump input shaft.

Abstract: A device for simultaneously or sequentially edge binding a sheaf of papers and separately laminating single sheets. A heat applying assembly includes a body of heat conducting material having a generally horizontal elongated slot extending through the body and two pairs of rollers, one at an input end of the slot and the other at an output end thereof for feeding a document between two thermoplastic sheets through the slot. Upper and lower imbedded heating coils apply heat above and below the slot for fusing the thermoplastic sheets to effect lamination of the document. The body of heat conducting material provides an upper surface slanted at an acute angle with respect to the horizontal. A rigid guide surface oriented by an equal angle with respect to the vertical provides for gravity retention of a sheaf of paper to be edge bound against the aforementioned upper surface, a heat setting adhesive being introduced along the common end of tyhe sheaf of papers thereby binding the papers along a spine.

Abstract: A coaxial cable structure for electrical signal transmission at frequencies up to the microwave region. The center conductor may be a conventional metallic conductor and the dielectric material between the center conductor and the outer coaxial shield conductor and the outer coaxial shield conductor may be conventional polyethylene or polytetrafluoroethylene. The outer conductor is formed over the dielectric layer acting as a mandrel by means of emplaced, small diameter carbon fibers stabilized in place by an impregnating resin. Use of a curable resin forms the cable rigidly. A variation employs braided carbon fibers without curable resin.

Abstract: A trailer or semi-trailer cargo container body clearance lighting system including a core light conducting material in the form of an elongated light-conducting strip clad about its cross-section with a translucent material layer having an index of refraction different from that of the core material to produce a light guide. The core and cladding are constructed to support lower and higher modes of light transmission and thereby provide lateral light emission as well as longitudinal propagation. A light source with light focusing reflectors is adapted to end-illuminate light guides for both sides of a container body from a single light source.

Abstract: A device for uniform and discretely controlled deposition of small quantities of viscous material at each of a succession of locations on a surface according to a digital X-Y-Z program. A particular application is for deposition of a viscous solder flux or slurry of very small solder particles in such a flux material, through a small (needle) orifice. A pumping valve is driven, typically by pneumatic pressure, during the brief dwell time of the needle at each programmed X, Y location, on an electronic circuit board or the like. A mechanical contact member is provided for automatically optimizing the needle orifice height (Z dimension) over each programmed location irrespective of irregularities or curvature of the plane of the circuit board. In an optional embodiment spaced needle orifices provide contemporaneous deposition of the viscous material. Rotating apparatus is provided for selecting the orientation of the needle orifices in the place of the surface.

Abstract: An electrical receptacle of the three contact type, one of which receives the standard, normally non-current-carrying, system ground pin of a corresponding cap.A set screw is advanced into a threaded bore in the plastic body material of the receptacle to make contact with the aforementioned ground pin. The bore may be from the receptacle front or from behind the face plate, in either case preventing the casual or surreptitious removal of the cap and cord and the associated equipment.

Abstract: Monitoring apparatus including an unmodulated radio-frequency transmitter carried by or affixed to the person to be monitored and receiver/monitor apparatus at a monitoring location for providing quantized visual and audible indicia based on received signal strength. The receiver AGC level, being a function of received signal strength, provides the variable which determines the repetition rate of tone bursts and the number of LED bar visual indicia lighted within an array of such LED bars. The response levels of those indicia are then a function of the distance between transmitter and receiver. Movement of the child (for example) beyond a predetermined range is immediately detected by a person at the receiver location. Circuitry is provided for presetting the maximum allowable range before alarm is instituted.

Abstract: A pipe cutting machine having a pair of parallel, horizontal driven rollers for supporting and rotating the work to be circumferentially cut. A cutter head assembly includes a free rotating cutter wheel on a shaft generally parallel to the driven rollers. Coarse vertical positioning of the cutter head is effected by sliding it up or down over a generally vertical support column. Detenting of this vertical positioning is effected by a spring-loaded pin engaging a selected groove among a plurality of vertically spaced, horizontally extending grooves associated with the vertical column. Vernier advancement of the cutter into the work is accomplished by an eccentric and lever arrangement associated with the cutter head assembly.A gear box arrangement couples the torque of a driving motor, which may be permanently or removably attached, providing drive to the rollers and to a reamer. A hand drill is shown positioned to provide motive power.

Abstract: A repetitively reusable envelope closure arrangement including a pair of thin magnetic plastic patches attached by a cementing agent to at least one portion of the foldable flap of the envelope and to at least one corresponding portion of the envelope body in contact therewith such that the flap is magnetically secured in a closure position. In an alternative embodiment, finely powdered magnetic material having a high order of magnetic retentivity is magnetized in the fluid medium of a standard gum and applied to at least one of the aforementioned envelope flap and body portions and a similar mixture of low retentivity magnetic material particles in gum is applied to the corresponding mating flap or body portion to effect a magnetically secured closure.

Abstract: A triangulated rib structure including first, second and third sets of "egg-crate" interlocking ribs. The first set is oriented in a predetermined direction such as the horizontal or vertical coordinate, and the second and third sets are oriented at angles of first and second senses, respectively, thereby forming triangulated spaces which are inherently rigid. The individual ribs have edges falling adjacent to a desired overall reflector surface, each of these being precut before assembly to provide the required line of curvature as a function of the individual ribs placement. Each rib is itself a planar piece, and the "egg-crate" interlocking slot joints may be stabilized with one or more seam welds. A conductive mesh forming the actual contoured reflector surface is conformed to the desired contoured shape and affixed as by tack-welding to the edges of the ribs adjacent the contoured surface.

Abstract: A regulated power supply for high voltage pulsed loads. An AC main or inverter circuit feeds the primary of a transformer which has a tapped secondary. The full secondary voltage is rectified through a diode to charge a main capacitor through a ground-end, low-voltage solid state control circuit. A sensing circuit detects the desired level of main capacitor charge and controls the solid state conductive element into current cutoff, by injecting a voltage step which holds off further main capacitor charging until the next load current pulse. The solid state circuits control operate at low level (ground-end of the high voltage main capacitor) and residual power supply energy is automatically shunted to an unregulated tapped output.

Abstract: A system including a frequency ramp generator feeding a transmitting power amplifier and antenna through a phase modulator and gain-controllable, transmitter driver stage. The frequency ramp generated is sampled out through a wide band delay-line feeding a phase comparator, the other comparison input to the phase comparator being provided by a sampling probe at the transmitting power amplifier output. The phase comparator output is used as a phase correction signal applied to the phase modulator and an amplitude modulation detector also responsive to the signal on the transmitting power amplifier output provides a feedback signal controlling the gain of the transmitter driver on a high bandwidth basis. Accordingly, instantaneous and long term frequency ramp phase and amplitude variations are substantially cancelled out so that the power amplified output is an accurate replica of the originally generated frequency ramp.

Abstract: A monopulse radar system in which circuits are included for specific identification of echoes from helicopters vis-avis other echoes. The identification is based on either the large Doppler spectrum of a helicopter echo or the amplitude modulation thereof, or both. Embodiments are shown which utilize these criteria for identification as well as bearing refinement. The apparatus is effective, even when a helicopter is hidden from the full view of the radar by foliage.

Abstract: A radar system is provided with first and second moving target indicator (MTI) systems. The first MTI system generally works better against ground clutter than against sky clutter. The second MTI system works well against sky clutter but generally requires a greater number of radar return echoes to discern targets in the sky clutter. A correlation estimation circuit is employed to calculate the correlation of clutter-like return echoes not suppressed by the first MTI system. If the return echoes are sufficiently correlated, the second MTI system is invoked against the clutter. If the return echoes are less well correlated, on the other hand, then electronic counter-counter measure systems may be invoked.

Abstract: Monitoring apparatus for a time reference scanning-beam microwave landing system which supplies directional information throughout a 40.degree. to 60.degree. landing approach sector. Several transponders are provided within the radiation field of the directional antenna of the landing system, these being directionally separated. Each transponder retransmits a part of the beam passing by it back to the directional antenna of the microwave landing system. The retransmitted signals are in converted form and are processed by the MLS system similar to radar echo signals, but are modulated at different discreet frequencies for identification. Errors are detected by comparing received transponder signals with locally generated reference signals at the MLS equipment.

Abstract: A card reader for a viewdata terminal such as PRESTEL in which a code in the card is read and used to enable access to the viewdata computer and to charge the appropriate account for use of the viewdata system. The reader detects voltage signals from capacitive couplings between electrodes in the card and in the reader assesses whether they are greater or smaller than a reference level to give binary 1 or binary 0 and compensates for capacitance variations by means of a "dummy" cell which adjusts the reference. Any variations in the signals caused by dirt et cetera affects the dummy cell equally and hence adjusts the reference accordingly. The reader operates in the static mode.
