Abstract: 668,197. Television. GENERAL ELECTRIC CO., Ltd., and KIRKNESS, R. H. July 24, 1950 [July 22, 1949], No. 19379/49. Class 40 (iii). In a conventional D.C. restoration circuit comprising a diode, condenser and resistance combination, distortion of the restored D.C. component, due to the inherent resistance of the circuit when the diode is conducting, is corrected by means of a compensating voltage injected in series with the diode. This distortion, which is manifest as a finite delay in restoring the D.C. component at the grid 10 of a valve 5, Fig. 2, (forming the output stage of a television amplifier) due to the timeconstant of condenser 11 and the inherent resistance of the D.C. restoring-diode 17 when it conducts during synchronizing intervals, is corrected by developing across condenser 22, which is connected in series with the diode 17, a voltage derived from the cathode resistance 12 which is of opposite phase to that at grid 10 and of an amplitude, determined by potentiometer 19, such as to compensate for the distortion. In order to prevent additional distortion of the reinserted D.C. component, caused by a rise in the potential of the grid during frame synchronizing periods (due to the difference in duration of the line and frame synchronizing signals), a further diode 32, Fig. 4, is arranged to supply a further compensating signal to condenser 22.

Filed: 1929-06-24
Abstract: 331,684. Kleinmann, E., and Mendel, A., (trading as Kleinmann, Geb.). June 24, 1929. Vacuum tubes. - A valve contact-plug consists of a single rectangular piece of sheet metal rolled about its longer centre line into cylindrical form and having a closed top. When such a plug is moulded in the base of a valve, the insulating material does not enter the plug. The top edge 5, Fig. 2, of the plate 4 is preferably of zig-zag form, the zig-zags being bent inwards to close the top; the angle between the sides of the top should be 80‹-120‹. The lower edge of the plate may also be formed with zig-zags 6, the points of the zig-zags being cut off, so that an opening for facilitating soldering of the leading-in wire is left when the zig-zags are bent inwards. In making a plug of banana shape, slits not extending to the ends are out in the plate, and in order to reduce the width of the openings formed by pressing the plate may be formed with one straight and one curved side. In manufacture, a plate with an embossed ridge 7 is rolled by bending it twice at right angles to form a channel section, and then pressing into a cylinder. The zig-zag ends are closed by dies and a second ridge 8, Fig. 4, is formed by pressing down the upper end. In order to prevent rotation within the moulding, interruptions 9 are formed in one or both ridges or rectangular bosses may be formed in the plate.

Abstract: 1502336 Vehicle lighting systems BAYERISCHE MOTOREN WERKE AG 13 May 1975 [13 May 1974] 20194/75 Heading H2H The headlamp lighting system of a road vehicle comprises a relay which controls the dipped beam filaments of the headlamps, the arrangement being such that as the system is switched from dipped beam to main beam lighting the dipped beam control relay remains operated. Movement of the switching member 5 of a lighting switch 1 to the drive position II causes contacts 8<SP>1</SP> to be connected together in groups for the normal lighting of a vehicle whilst simultaneously connecting contacts 6, 7 together whereby to cause energization of the coil 15 of a dipped beam relay 3 so as to close contacts 16, 17. With a main beam/dipped beam/headlamp flasher switch 2 in the centre position a the coil 12 of a main beam relay 4 having change-over contacts remains unenergized, the movable contact 20 thus being in contact with contact 21. Dipped beam filaments 28a, 28b are thus energized over contacts 20, 21; 16, 17 from a supply terminal 23. If the switch 2 is moved to the right hand position b, the coil 12 of the main beam relay 4 is energized causing contact 20 to move to contact 22 whereupon main beam filaments 33a, 33b are thus energized from terminal 23 the dipped beam circuit over contacts 20, 21 being broken but the dipped beam relay 3 remaining energized. Movement of the switch 2 to the left hand position c causes energization of the main beam relay 4 to flash the main beam filaments 33a 33b irrespectively of whether the switch 1 is in a position to cause energization of the dipped beam relay 3 or not the dipped beam relay 3 remaining energized however, should the switch 1 be in the position II when the headlamps are flashed. The system includes a potentiometer 8<SP>11</SP> for dimming the panel lamps of the vehicle. Terminals 13, 23, 19 are only supplied when the ignition switch is ON. A second embodiment is disclosed with opposite polarity supply to that in Fig. 1.
