Abstract: COUPLING ASSEMBLY                     Abstract of the Invention A coupling assembly for fluid-flow systems is dis-closed which includes both a coupler and a nipple.  The mating or sealing surfaces of the coupler and nipple are protected from dirt and other deleterious substances by corresponding movable covers.  The movable covers not only protect the mat-ing surfaces but present flush faces for the coupler and nip-ple which are easily cleaned.  The construction of the coupling assembly is designed so that connection of the coupler and nip-ple may be accomplished by using only one hand.  The coupler is designed so as to render the adapter and the valve a one-piece structure.

Abstract: URANIUM LOGGING IN EARTH FORMATIONS     Abstract of the Disclosure A technique is provided for assaying the formations surrounding a borehole for uranium.  A borehole logging tool cyclically irradiates the formations with neutrons and responds to neutrons during the period of time that prompt neutrons are being produced by the neutron fission of uranium in the forma-tions.  A borehole calibration tool employs a steady-state (continuous output) neutron source, firstly, to produce a response to neutrons in models having known concentrations of uranium and, secondly, to produce a response to neutrons in the formations surrounding the borehole.  The neutron responses of the borehole calibration tool in both the model and the forma-tions surrounding the borehole are utilized to correct the neutron response of the borehole logging tool for the effects of eptithermal/thermal neutron moderation, scattering, and absorption within the borehole itself.

Abstract: ABSTRACT OF THE DISCLOSURE               A wall storage system makes use of a support rail horizontally attached to a wall.  The rail may be offset from the wall between its ends and has one or more vertical grooves across its width.  One or more brackets formed with a U-shaped arm section to support a load are attached to the rail by an inverted U-shaped fastener section.  A protrusion at the open end of the fastener causes it to grip the rail and yet permits the bracket to be mounted on the bar at the groove.  Once the 0 bracket has been slid along the rail out of the groove area, it is captured on the rail and provides firm support for the load.

Abstract: PHN.8739 ABSTRACT:               An optical scanning device which scans a rotary video disc with the aid of a light beam comrises an objective which performs focussing movements, for focussing a light spot on a recording surface of the video disc, as well as tilting tracking movements and time-error correction movements. Near its lower end the objective is suspended in an impregnated corrugated loudspeaker diaphragm of fabric fibre which enables the various movements of the objective to be made without giving rise to annoying resonant effects. The tracking move-ments and the time-error correction movements are obtained with the aid of coils which are connected to the objective near the upper end and which are disposed in air gaps of as-sociated permanent magnetic stators.

Abstract: ABSTRACT OF THE DISCLOSURE         A swath pickup includes a pair of spiders one on each end of a frame and angulated with respect to the direction of travel.  A forked inwardly offset arm is pivotally secured to blocks on the outer ends of each arm of the spiders in the form of a universal joint and a transversely extending member from which pickup teeth extend, extends between each offset arm on one spider and the corresponding offset arm on the other spider.          The spiders are rotated by a motor and the angular relationship of the spiders causes the members and the pickup teeth to re-ciprocate transversely as they rotate.  The offset arms enable a pickup of reduced diameter to be provided  which increases the efficiency of the pickup action yet provides sufficient room at the spiders for the installation and operation of the universal joints and arms to the spiders.

Abstract: D-21,022 APPARATUS AND METHOD FOR REMOTE TESTING               OF A LOOP TRANSMISSION PATH   by Tom L. Blackburn ABSTRACT OF THE DISCLOSURE          A first network can be switched into and out of connection with a lowpass filter disposed at one of the two opposite carrier terminal ends of a loop transmission path employing a double-sideband carrier.  When the filter and network are so connected, an oscillator producing a first test signal of selected frequency and amplitude is formed.  This signal modulates the carrier wave generated by the existing carrier oscillator at this terminal end.  The modulated signal passes along the path to the opposite terminal end where it is demodulated and detected.  The detector threshold is set so that the detector responds to the demodulated first test signal, but does not respond to normal voice and other test signals.          The detected demodulated signal energizes the station carrier oscillator at the opposite end whereby it's carrier wave is modulated.  The resultant second modulated test signal passes back along the path to the original terminal where it is demodulated, and the presence of the carrier is detected.  The amplitude of the demodulated signal also may be measured and compared to that of the original test signal to establish the loss in the transmission path.

Granted: 1982-11-23
Abstract: Abstract A method for constructing a gas discharge display with-out the utilization of an exterior exhaust tubulation structure. When the face plate and base plate of the display device are as-sembled in face-to-face relation, irregularities in the sealing frit material provide vias to the interior envelope of the gas display device to allow evacuation of the envelope and the intro-duction of the ionized gas.  The frit material is preglazed to ensure a hermetic seal between the plates when the frit is melted. Specially designed biasing means are attached to the plates to provide a tighter force between the plates while the frit material is being melted and devitrified to seal the interior envelope containing the ionizable gas.

Abstract: HIGH-RATIO-ACCURACY CAPACITOR GEOMETRIES           FOR INTEGRATED CIRCUITS          Abstract of the Disclosure A number of known circuit configurations require high-ratio-accuracy capacitors.  Maintaining such ratios during the various processing steps involved in fabricating the configurations in integrated-circuit form has been found to be difficult.  In accordance with this invention, ratio capacitors are made in integrated-circuit form utilizing a unique geometry.  In one specific embodiment, a so-called H-section geometry that is largely insensitive to processing variations is utilized to form the capacitors. In this way, high-yield low-parasitic precisely matched pairs of ratio capacitors are achieved.
