Title: Improvements in or relating to high frequency transmitters
IPC: H03C1/06
Filed: 1939-03-25
Abstract: 526,720. Wireless transmitting systems. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. March 25, 1939, No. 9416. Convention date, March 26, 1938. [Class 40 (v)i] In a high-frequency transmitter in which distortion is reduced by feed-back of the lowfrequency component obtained by rectification of the modulated output, non-rectilinear action of the rectifier at high degrees of modulation is prevented by reducing the depth of modulation by the addition of carrier in the rectifier circuit. The transmitting valve R is supplied with carrier from T and modulation from M. A modulated high-frequency component is obtained in the coupling coil CC from the output circuit OC, and is rectified at G to' obtain a modulation voltage which is combined with the original modulating voltage in a bridge B. The difference voltage occurring across arm Z, which corresponds to the distortion in valve R, is then applied to the grid circuit of the valve in a sense to compensate for distortion. Carrier-frequency oscillations are superimposed by means of a coil CK in the rectifier circuit, and are obtained from T via a phase-adjusting arrangement P.

Title: Discrete four-channel disc reproducing system
IPC: H04S3/00
Filed: 1975-03-10
Abstract: 1498065 Quadrophonic decoders MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 10 March 1975 [12 March 1974 28 March 1974 10 April 1974 (2)] 9903/75 Heading H4R The adverse effects caused by dropouts in the modulated carrier component in a discrete LI-CH disc owing to dust &c. are reduced by detecting 9 the carrier component, muting 10 the component during a detected dropout and further attenuating 12 at least the high frequency band of the remaining signal for a period longer than the duration of the dropout. Fig. 1 shows the system for left or right channels in which a low pass filter 2 extracts the main component for a matrix circuit 4 whilst a band pass filter 7 routes the subcarrier component through the muting circuitry detailed in Fig. 2. Here the FM detector 9 converts the carrier to a pulse waveform to reset a ramp generator Q1 R1 C1 except when pulses are absent owing to carrier dropout. Excursions of the ramp voltage above a threshold set by D1 turn on transistor Q2 to discharge C2 and thereby open FET switch Q3 for the duration of the dropout. The waveform at f still contains distortion owing to the switching action. The switch-controlling signal c therefore turns on Q4 to discharge C5 and thereby turn on Q5 which, via C6, shunts to earth at least the high frequency components of the signal at g for a time dependent on the time sustant of C5, R8, R10. In a modification (Fig. 4, not shown) time sustant circuits (R11, C11) and (C13, R16) ensure that a pilot lamp is not extinguished during carrier dropout and is not illuminated by harmonics of a 2.CH stereophonic disc. In a further modification (Fig. 7, not shown) the output of the equalizer 11 is fed to the base of a transistor (Q31) in the attenuator control circuit 15 to produce a collector output which is rectified and which negatively charges a capacitor (C34) to bias off a transistor (Q33) which, when a dropout occurs, turns on and attenuates the high frequency components. The output from the carrier amplifier is also rectified (D31) and fed through a time constant circuit (C31, R32) to the transistor (Q31) so that even if the first controlling input from the equalizer 11 is large, high frequency attenuation is still effected should the carrier level fall. Similarly attenuation is maintained by an output from the switch operating circuit 14 through (Q32) and a time constant circuit (C36, R36).

Abstract: Components, usually but not exclusively gaseous components, are removed in a liquid medium from gas streams and chemically converted into an insoluble phase or physically removed. Specifically, hydrogen sulfide may be removed from gas streams by oxidation in aqueous chelated transition metal solution in a modified agitated flotation cell. A gas-liquid contact apparatus, generally a combined chemical reactor and solid product separation device, comprising such modified agitated flotation cell also is described. In order to effect efficient mass transfer and rapid reaction, gas bubbles containing hydrogen sulfide and oxygen are formed by rotating an impeller at a blade tip velocity of at least about 350 in/sec. to achieve the required shear. To assist in the reaction, a surrounding shroud has a plurality of openings, generally of aspect ratio of approximately 1, of equal diameter and arranged in uniform pattern, such as to provide a gas flow therethrough less than about 0.02 lb/min/opening in the shroud. In general, the gas velocity index is at least about 18 per second per opening, preferably at least about 24 per second per opening. Each of the openings has an area corresponding to an equivalent diameter less than about one inch.

Filed: 1990-05-08
Abstract: The invention describes an automatic sliding door with at least one panel (1, 1') and with an auxiliary drive unit (14). When the door closes normally, energy is supplied to the auxiliary drive where it is stored. In the event of a power failure and/or simultaneous interruption of the normal drive, this stored energy is then used to open the door. The auxiliary drive (14) is preferably a rubber element which is under tension when the door is closed. In the event of a power failure, a coupling (20) between the drive motor (9, 22) and an actuation device (19) is opened and the rubber element contracts, thus opening the door.
