Title: Improvements in or relating to cathode ray television apparatus
IPC: H01F19/00
Filed: 1943-11-01
Abstract: 580,413. Television receivers. GES. ZUR FORDERUNG DER FORSCHUNG AUF DEM GEBIETE DER TECHNISCHEN PHYSIK AN DER EIDGENOSSISCHEN TECHNISCHEN HOCHSCHULE. Nov. 1, 1943, No. 18069. Convention date, June 5 [Classes 40 (iii) and 40 (v)] In a television receiver including a cathode ray tube in which the screen is deformed locally so as to vary the light transparency in accordance with the amplitude of the received signal and in which the rastering is effected by superposing fixed frequency oscillations on the line deflection of the cathode ray beam without altering the mean velocity of the fixed frequency oscillations are produced by an oscillator which is cut-off and restarted under control of the line synchronising signal during the retrace time. In the arrangement shown in Fig. 1, the fixed frequency oscillations are produced in a push-pull circuit comprising tubes 16, 17 and fed to a modulator 13 which produces a deflecting field between plates 12 for deflecting the beam parallel to the line deflection between plates 5. The amplitude of the output of modulator 13 is controlled by vision signals fed via line 14 from a separator circuit 21, which supplies line synchronising pulses via time-constant circuit CR to the damping tubes 24 which are rendered conducting by the pulses to prevent the oscillator functioning and are rendered non-conducting at the end of each pulse to permit the oscillator to re-start. Figs. 2 and 3 show alternative arrangements for controlling the operation of the fixed frequency oscillator. In Fig. 2, the line synchronising pulses are fed via a tube 30 to control a multivibrator 31, 32 which has an adjustable time constant C, R, and is arranged to produce output pulses slightly shorter than the synchronising pulses for controlling the damping tube 24. This arrangement ensures a sharp cut-off and prompt re-starting of the fixed frequency oscillator. To improve the operation of damping tube 24 feedback may be provided to reduce its impedance, for example through an impedance 36 connected between the anode and control electrode of the tube. If sufficient feedback is provided tube 24 may be a pentode. In Fig. 3 the oscillator tube 29 constitutes a cathode load for the damping tube 37 thereby affording a high degree of feedback. Alternatively the damping tube 37 may be coupled to the output circuit of the oscillator via coil 39, connection 41 being omitted. The alternative connection in Fig. 3 avoids the necessity for a very high anode potential for tube 37. Specification 546,462 is referred to.

Abstract: 220,433. Zink, J. E. July 16, 1923. Wire couplings.-Relates to a tube retainer for electric wiring, comprising an apertured disc arranged to be threaded on the wire and adapted to be movable in one direction onlv so that the disc may be moved adjacent to the insulating-tube to prevent relative movement of the tube and the wire in the opposite direction. The attenuated retaining edge 3 of the disc 1 moves outwardly when the disc is moved along the wire 11, and grips the wire. thus preventing movement of the disc in the other direction. The disc has a split 4, which can be expanded to receive the wire and to reduce the pressure as the disc is moved along the wire. The edges of the split are bevelled to permit relative transverse movement in one direction only.

Abstract: 319,641. Distillers Co., Ltd., Bennett, W. G., and Peake, A. M. June 25, 1928. Purifying saccharine liquids.-Colloids, colouring matters, and metallic salts are removed from molasses of any kind by treatment in the neutral or slightly acid condition with an adsorbent that does not 'contain free carbon and at the same time or. subsequently with a protein precipitant in the presence of protein and filtration after each treatment. Any excess of protein remaining in the solution after treatment is, if desired, converted into a food suitable for yeast. A suitable protein precipitant is synthetic or natural tannin, and suitable adsorbents are ground nut cake when operating in two stages or calcium carbonate when operating in one. A suitable protein such as blood serum is added to the molasses if deficient in protein. The filtered nut cake can be treated in the usual way for the preparation of peptone from which iron is removed before using.

Striking-plates for latches. -In a modification of the fastening described in Specification 138,777, the latchretaining device is unbalanced and tends to rotate to releasing position, but can be held by means released by raising the latch. An eccentrically weighted disc B<2> pivoted at B to a base-plate C has notches A, b. Also pivoted to the base-plate at f is a pawl F which normally hangs down and engages in the notch A, holding the disc B<2> in position for retaining the pivoted latch G. On lifting the latch to clear the point b<1> of the disc to open the gate, the upper face of the latch displaces the pawl from the notch A and allows the disc to rotate until the face rests against the base-plate, when the notch b is in the inoperative position, as shown by the broken lines in Fig. 1. On closing the gate, the latch G hits the point B' and carries the disc round until the pawl F engages the notch A, retaining the disc in its operative position for holding the latch.

In the construction shown, a rotary disc 16 driven by the clockwork spring 12 is interposed between the firing pin 10 and the priming charge 11. The disc is provided with an arcuate slot 17, which is of such a length and so disposed that it is brought into alignment with the firing pin after the first predetermined time interval, and remains in alignment therewith, to allow the passage of the firing pin, during the second predetermined time interval. According to a modification, the disc 16 may be interposed between.the priming charge and the detonator.

Abstract: 1300061 Filling containers GIMSON & CO (LEICESTER) Ltd 6 July 1970 [15 April 1969] 19135/69 Heading B8T An apparatus for filling a keg 1 or other container having a closure valve with beverage, e.g. beer, includes a dispensing head 10, e.g. under which the keg is moved by a conveyer, the dispensing head 10 having a beverage inlet controlled by a valve 6 and an outlet for displaced gas, e.g. controlled by a solenoid valve 11, a valve opening member, e.g. a skirt (13), Fig. 2 (not shown), and means which causes the head to be depressed, e.g. a pneumatic ram 4, to engage and open a keg closure valve 2, a pressure sensitive device 7 being provided to sense the pressure within the keg, and means activated by said device to close the inlet valve when said pressure rises due to beverage obstructing said outlet. The keg may actuate a switch 3 which causes the head to be depressed and also opens the inlet valve 6. As the keg fills, displaced gas exits through the outlet until this is blocked by the liquid level, pressure then rising until it actuates high pressure contacts in a sensor 7, via a pressure line 12, to close valve 6. Valve 11 may also be moved into a fully open position in which it will rapidly pass the excess beverage. Keg pressure therefore diminishes and low pressure contacts in the sensor 7 are actuated to retract the ram. The keg may be pre-charged with CO 2  via a line (19), Fig. 3 (not shown), and the beverage inlet may have a valve (15), and the gas outlet a non-return valve (22) to prevent beverage drips from the retracted head. The kegs may be filled in the inverted position and may be steam cleaned via the head.
