Title: Improvements in or relating to television apparatus
Inventor: CASLING WHITE ERIC LAWRENCE
IPC: H03K17/54
Filed: 1946-01-15
Abstract: 615,638. Television transmitters. WHITE, E. L. C., and TROTT, F. R. Jan. 15, 1946, No. 1312. [Class 40 (iii)] [Also in Group XL (c)] In a television transmitter wherein means are provided for effecting a rapid change in the level of the television signal (e.g. by switching from one camera to another, or by varying the amplitude of the output of a single camera), means are also provided for ensuring that the change can only occur during the interval between successive frames, so as to eliminate the undesirable disturbance that would otherwise be produced in the received picture. In Fig. 1, the channels 1 and 2 from two different cameras may be alternately switched to the output channel 3 by means of a moving contact 4. A pair of commutators 9, 10 are mounted on a shaft rotating at the frame frequency so that the conducting segment of commutator 9 is in contact with brush 14 and the insulated segment of commutator 10 is in contact with the brush 15 during the intervals between successive frames. When the key 11 is depressed, current flows through the relay 5 during the next such interval, thereby actuating the contact 4 and the self-holding contacts 17. When the key is opened again, the self-holding contacts open during the next interval between frames and contact 4 operates in the reverse direction. In an alternative embodiment, Fig. 2, a cathode-coupled " flip-flop " circuit is employed, the critical potentials of the grid of valve 19, corresponding to the two stable conditions of the circuit, being illustrated as E1, E2 in Fig. 3. The potential of the grid of valve 19 is shown as 24 with the key 11 in the position shown, and as 23 with the key in the other position. Narrow rectangular pulses, which are differentiated to form pulses 25, 26,. are applied to the condenser 27 during the intervals between successive frames, so that, with the key 11 as shown, each pulse 26 drives the grid of valve 19 beyond the potential E2 and the circuit assumes the condition wherein the valve 19 is cut off. Conversely, when the key 11 is placed in its other position, the valve 20 is cut off during the next following frame interval. A relay 5, operating contacts as in Fig. 1, is placed in the anode circuit of valve 20. The relay 5 may be replaced by diode switching circuits, Fig. 4 (not shown), comprising two pairs of diodes, each pair with their cathodes connected together and coupled either directly or through a further valve circuit, to an output point of the circuit of Fig. 2, so that in one condition of that circuit a negative potential is applied to the cathode circuit of one pair of diodes whereby a conductive path exists between their anodes, and in the other condition a negative potential is similarly applied to the cathode circuit of the other pair. In order to provide a low impedance output, the diodes may be replaced by pentodes to which negative feed-back is applied as described in Specification 564,821.

Title: Apparatus and method to count and control crimps in a moving tow of yarn
IPC: D01G1/06
Filed: 1979-03-14
Abstract: The apparatus comprises a target (the tow of yarn) (1), a stroboscopic light (2), condenser lens (3), mirror (4), transparent support (5), for the target, focusing lens (6), diode array (7) to sense variations in light intensity from the striations in the target, electronic board circuit with terminal board, programmable calculator, and read- out means, such as a light emitting diode display. When used to control the crimping apparatus it also comprises a controller, exit control gate of the crimper and means to exert pressure on the exit control gate. The method is to cause an intense light pulse to issue from the stroboscopic light, passing the pulse of light through the condenser lens against the mirror through the transparent support to reflect from the striations in the yarn tow back through the focusing lens into the diode array which counts the variations in light intensity caused by the striations. The variations counted are transmitted from the diode array as an electronic signal to optional storing and averaging means, such as a programmable calculator, then a read- out device. When controlling crimp, the signal is transmitted to a controller which influences a means to change crimp in the crimping apparatus, such as pressure on the exit control gate of a stuffer box crimper. <IMAGE>

Title: Machine for making ice-cubes
IPC: F25C1/04
Filed: 1979-05-08
Abstract: A machine for making ice cubes comprises a tray containing a horizontal evaporator, inverted receptacles (10) of rectangular cross- section into which water is sprayed under low pressure from rotating nozzles (26), and a peripheral drainage trough 13. The water jets align with slots (15<1>, 15<11>) in a sloping tray (15) onto which the ice cubes fall to allow the water to pan.

Title: Security documents
IPC: G03G21/04
Filed: 1979-09-13
Abstract: A document bearing a reproduction- resistant security pattern comprises (1) an image including at least one plurality of parallel spaced-apart lines oriented in a first direction and (2) a background including at least one other plurality of parallel spaced-apart lines oriented in a second direction different from the first direction. The line thickness, line spacing and relative contrast between the lines and spaces are substantially the same for both the image and background. Consequently the artwork appears as a uniform tint and the image merges with the background when viewed on the original document with the naked eye, but becomes discernible when reproduced with a line by line electrophotographic copier of, e.g. the rotary type. Image/background line set pairs may be arranged at a variety of angles to the document axes to defeat any attempt to defeat the security pattern by feeding the document slant wise through a copier.   <IMAGE>

IPC: B62D25/16
Filed: 1980-04-15
Abstract: In a method of suppressing spray at least one strip of bristles is located to intercept the spray thrown out by a vehicle wheel. The strip of bristles may be located around the concave arcuate periphery of the mudguard with the bristles close to or touching the wheel, and/or one or more may extend transversely across the wheel arch inwardly from the mudguard to catch the spray as it is thrown off the wheel. Alternatively, or additionally, the strip may be provided in place of the traditional mud flap. The strip of bristles preferably incorporates a flexible backing member which is attached to or integral with a flange gripping beading of generally U-shaped cross-section to allow the strip easily to be connected to a mudguard.

Title: Egg conveyor system
IPC: B65G47/68
Filed: 1980-04-28
Abstract: In an egg conveyor system eggs discharged from laying cages at different levels are delivered to adjacent ends of respective longitudinal conveyors 5-8. The lowest longitudinal conveyor discharges eggs transversely onto a wide delivery conveyor 12 and each upper longitudinal conveyor discharges eggs transversely onto an inclined transfer conveyor 9-11, respectively. These deliver eggs adjacent one longitudinal edge of the main conveyor 12 at lower ends 13-15 spaced apart in the longitudinal direction of the delivery conveyor 12. The eggs on the delivery conveyor 12, which comprises rods 24 connected between a pair of endless chains, are guided into separate streams across the width of the delivery conveyor 12 by stationary guiding walls 16-18.

Patent GB-2080104-A (GB)
Title: Liquid detector for actuating an umbrella
IPC: G01N19/10
Filed: 1980-07-24
Abstract: The invention is an umbrella device which is attached to the top of a rotary washing line and when rain starts to fall, the umbrella opens out automatically to cover the washing on the line. To detect the rain fall, blotting paper is used. The blotting paper is held under spring tension and when rain falls the paper tears due to the soaking and the tension upon it. The stays of the umbrella are held up by a heavy ring which falls when the blotting paper tears. This ring is supported by a pin which protrudes under the ring from the main body structure. As the paper rips, the spring pulls the pin from under the ring. This in turn allows the umbrella to cover the washing, thereby keeping it dry.
