Filed: 1947-10-28
Abstract: 649,537. Automatic tuning control. ANDREWS, E. F. Oct. 28, 1947, No. 28805. Convention date, Nov. 1, 1946. [Class 40 (v)] Radio apparatus comprises tuning means which on being varied to turie in a signal causes the operation of a relay to release a resiliently applied brake and stop the variation of the tuning means. The invention is embodied in the stop-on-signal radio receiver described in Specification 649,536, in which the means for obtaining the control voltage for operating the relay to release the brake is the same as in Specification 633,397. A modification is described in which the gas tube for operating the stop-on-signal relay is replaced by a vacuum tube, and the circuit is arranged so that the anode circuits of the auxiliary control tubes are opened on the cessation of tuning to economize power. Also the operation and release of the relay may be effected by opposite currents in a single coil, instead of having an operating coil and a bucking coil. Fig. 2 shows part of a modification in which a motor 145 is adapted to drive the main tuning condenser shaft 151 continuously in one direction through clutch members 143, 142, and gearing 146 ... 150. Release of flux-latched relay 105 due to a voltage applied to bucking coil 116 allows spring 114 to rotate armature 113 which moves spindle 141 to the right to declutch the motor 145. Also clutch member 142 engages brake surface 155 to prevent overrunning of the condenser shaft. The motor circuit is simultaneously broken at contact 109. U.S.A. Specifications 2,262,218 and 2,326,738 also are referred to.

Title: Improvements in or relating to apparatus for recording television and like pictures on cinematographic film
IPC: H04N5/84
Filed: 1947-10-30
Abstract: 640,186. Television. CINEMA - TELEVISION, Ltd., and JESTY, L. C. Oct. 30, 1947, No. 28991. [Class 40 (iii)] In an arrangement for recording on intermittently moving cinematographic film television pictures produced on the fluorescent screen of a picture reproducing cathode-ray tube the duration of the after glow of the fluorescent screen is such that the portion of the picture which is reproduced during movement of the film is photographically effective during the subsequent exposure of the film. In the arrangement described double interlaced television pictures to be recorded are reproduced on the fluorescent screen of a picture signal reproducing tube and the intermittent drive camera mechanism, having a 50 per cent pullthrough time, is so arranged that the shutter obturates the film during alternate field scans which, due to the after-glow period of the fluorescent screen, are retained as luminous images and photographed on the next film frame. To ensure that the brightness, when photographed, of the after-glow images is comparable with the brightness of the directlyphotographed images, the gain of the television receiver, which supplied the image signals to the reproducing tube, is pulsed so that the initial intensity of the former images is increased. The invention is also applicable to television systems employing sequential scanning.

Title: Devices for supervising and controlling the continuity of textile production processes
Filed: 1952-11-18
Abstract: 743,905. Spinning yarns; stop-motions. BREUNING, E. Nov. 18, 1952 [Nov. 19, 1951], No. 29129/52. Classes 120 (2) and 120 (3). In apparatus for supervising or controlling the continuity of textile production processes, e.g. operable in response to breaking or tearing of a sliver or breakage of a thread, an electric circuit is closed by the textile material itself, e.g. cotton or wool sliver, slubbing, or yarn to which no conductivity-increasing medium such as a conducting liquid is applied. In the operation of the device shown in Fig. 1, slubbing 1, departing from its normal path between earthed drafting rollers 2 and 3 and a spindle 4, consequent on breakage, contacts a conducting body 5 mounted on insulators 6, thus establishing electrical connection between rollers 2 and 3 and a lead 7 to produce an indication on an instrument 10 in an observation and control instrument 8 which is earthed at 11: the sensitivity of the device is increased by provision of a conducting earthed body 12 which shortens the length of slubbing through which current flows. As shown in Fig. 2, the lead 7 is connected with an insulated fixed body 16 opposite which is a conductor 17 movable around a mounting 18 and carrying a contact 19 lying opposite a fixed adjustable contact 20. When a voltage drop occurs across a high ohmic resistance 14 due to current flow therethrough, the conductor 17 is attracted electrostatically by the body 16 so that 19 and 20 contact: a source of potential 21 such as a battery or accumulator connected to the conductor 17 through the mounting 18 and to an indicator or control device 22 produces an operating current in the latter. The resistance of 14 is at least equal to the input resistance of the device 22. The electrode 5 may be hollow and provided with apertures through which particles of material may be removed by pressure or suction. The indicating and/or control means may comprise an electronic tube with high input resistance or conventional bridge circuit arrangements.
