Abstract: An improved socket assembly for a fluorescent fixture is provided in which a terminal floats on a pair of guide posts. A spring exerts a biasing force on the terminal urging it into position to receive and retain the pins of a fluorescent tube.

Abstract: A garden light fixture is provided comprising a cylindrical housing about which a plurality of shades extend. The intermediate and top shade are secured to the housing by means of keyways formed integral with the shades which engage and are captured by slots formed in the housing.

Abstract: A quasi-doppler direction finder is provided wherein the alternate dipole elements are divided into two groups. Each of the groups is connected to an associated RF attenuator which is driven by a control signal 180.degree. out-of-phase from that for the other group. Commutation between dipoles occurs so that there is a 50% overlap of "on" time between adjacent dipoles. Switching for each dipole occurs when its associated modulating function passes through zero.

Abstract: Indium is recovered effectively from an aqueous leached solution containing indium ions, together with other ions such as ferric ions, zinc ions, etc. if any, by adjusting the pH of the aqueous solution to 0.25-4.5, extracting the indium ions from the aqueous solution with an organic solvent solution formed by diluting an extraction reagent containing a monoalkylphosphoric acid and/or a dialkylphosphoric acid and a trialkylphosphoric acid in 1:2-5 by volume ratio with a phase-stabilizing water-immiscible organic solvent and then back-extracting the indium ions in the organic solvent solution with an aqueous sulfuric acid solution.

Abstract: A process for depositing a metal or alloy layer on an electrically conductive work piece by means of a glow discharge. The work piece is inserted as one electrode of an electric field in a low-pressure chamber charged with a preionized carrier gas and coating material or spender medium. An arc discharge is utilized for explosively spattering the spender medium.

Abstract: A circuit for generating an audible signal in a tape recorder as the tape approaches its end. The circuit includes an open loop extending between the recording amplifier and loudspeaker. The loop is closed by the metallic foil at the end of the tape when the foil bridges a pair of contacts. In the case where an exterior microphone is used with the recorder the speaker signal is electrically fed back to the amplifier.

Abstract: A telephone display device comprises a pair of spaced apart legs, an easel mounted to the tops of the legs and a support member extending transversely across the bottom of the legs. The support member is proportioned to fit within the hand grip opening at the back of a telephone set and contains resiliently biased lugs to lockingly engage surfaces of the telephone. The easel extends above the telephone receiver when the display stand is in position and includes spaced lugs for capturing the binding of an information containing booklet.

Abstract: Vinegar having an acetic acid concentration higher than 18 percent weight by volume is produced in a submerged fermentation by maintaining the temperature of the fermenting broth after the initiation of the fermentation at 27.degree.-32.degree. C. until the acetic concentration of the fermenting broth reaches 12-15 percent weight by volume and thereafter maintaining the temperature of the fermenting broth at 18.degree.-24.degree. C.

Abstract: A data communication system is provided comprising, at a plurality of locations, data terminal equipment. Communication equipment adapted to transmit and/or receive data from location to location is provided at each location connected to the terminal equipment and interconnected between locations through a suitable communications channel or media. An auxiliary signal processor is provided at each location interfaced with the communications equipment and deriving from the communications equipment on a noninterfering basis, information relating to the status of the channel, communications equipment, and data terminal equipment. A central controller is provided at a central location and auxiliary communication equipment is provided at each location interconnected with the central controller and with the auxiliary signal processor.

Abstract: A system is provided for increasing the recording/play-back time for video tape devices. A tape is utilized on which signals are recorded in one direction for one half the tape width and in the opposite direction for the other half of the tape width. The tape drive mechanism automatically reverses at the end of feed in each direction and when the tape feed direction changes the relative vertical position of the tape head (or heads) with respect to the tape also changes.

Abstract: An improved method is provided for the complex plane mapping of the signal structure constellation for double side band quadrature carrier modulation. All points are mapped in an N.times.N constellation having 90.degree. symmetry about the origin. All points in excess of 2.sup.M and any point appearing at origin are omitted. Any point, in each quadrant further spaced from the origin than any other point in that quadrant are relocated. "N" and "M" are integers.

Abstract: A device to simulate the rolling of a hypothetical wheel along a path is provided. The device includes a wheel sector mounted to one end of a rotor. A drive is provided for rotating the rotor in one direction and the sector in the opposite direction so that the sector remains substantially tangent to a line segment. The wheel sector is driven by a pulley the diameter of which is one-half that of a drive pulley rotated with the rotor.

Abstract: An improved electrical junction box particularly suitable for outdoor use is provided. The junction box contains a plurality of mounting holes each of which is closed by a grommet. The mounting holes are defined within lugs having raised and depending portions with a flange extending therebetween. The grommet is provided with a circumferentially extending groove into which the lug flange seats. Counterbores extend from the top and bottom end of the grommet terminating short of each other whereby to define a web section. The grommet groove extends about the web.

Abstract: An electromagnetic pump characterized in that two independent coils disposed adjacent each other and via a common magnetic path are used for actuating a plunger and a valve, respectively, thereby preventing the generation of noises and abrasion during the operation of the pump. This also attains the quick return of the valve to its home position at the time when the pump stops, thus resulting in the complete stoppage of oil leak.

Abstract: A facsimile reproduction system is disclosed. The system utilizes a laser beam at the transmission station to scan across an image to be reproduced through an acousto-optic modulator (AOM) cell. The laser beam is reflected off the image onto photo detector cells to generate electrical signals analogous to tonal variation in the image. A laser beam at the receiver station is also provided to sensitize a sheet of sensitized paper to produce a facsimile of the image. The intensity of the receiving station laser beam is modulated in accordance with the photo detector electrical signals by applying the signals to an rf carrier which then is applied to an AOM cell positioned between the laser and sensitized paper.
