Title: Improvements in or relating to television receivers
Inventor: EDWARDS WILLIAM THOMAS
IPC: H04N5/46
Filed: 1965-04-29
Abstract: 1,123,026. Television. COMMUNICATIONS PATENTS Ltd. 28 April, 1966 [29 April, 1965], No. 18050/65. Heading H4F. In a television receiver required to operate at two or more line-scanning standards, a pulse detector 6, Fig. 1, provides an output signal in response to the application thereto of synchronizing pulses pertaining to a line standard different from that for which a line standard control 5 is adjusted, this output signal being used to adjust the line standard control to the other or a different line standard. In the embodiment described synchronizing pulses are applied at terminal 8 and switch 7 applies such pulses to one or other of resonant circuits 9 and 10 tuned to resonate at the frequency of the 405 and 625 line standards respectively. Switch 7 is coupled or ganged with switch 5 so that if the transmission has a line standard other than the line standard to which switch 5 is set, the line synchronizing pulses received will result in energization of an electro-mechanical device 12, for example, to adjust the switch 5 to the alternative line standard. A circuit arrangement for use in such an automatically operating standards control may include an auxiliary synchronizing pulse separator, Fig. 2 (not shown), which is additional to the one normally included in the receiver and is arranged to separate synchronizing pulses from video signals the polarity of which are opposite to that for which the receiver is conditioned.

Title: Improvements in or relating to apparatus for casting stereotype printing plates
IPC: B41D3/00
Filed: 1945-07-16
Abstract: 596,042. Casting stereotype plates. GOSS PRINTING PRESS CO., Ltd. July 16, 1945, No. 18169. Convention date, July 15, 1944. [Class 100 (ii)] In apparatus for casting stereotype printing-plates, of the kind comprising a rotatable cylindrical core 6, Fig. 2, carrying two adjacent casting- surfaces, and a concave casting-member 3 carrying a matrix 10 and co-operable with the core to form a casting space, two auxiliary core elements 20 are' pivotally mounted in the core each having two sets of projections 25, 26, thereon shaped to form recesses in the cast plates, each element being actuated in timed relations with the rotary movement of the core to cause one set of projections to be projected beyond one casting-surface on the core and into the casting space as the other set is retracted from a previously cast plate and beneath the other casting-surface. The member 3 is movable on tracks 5 towards and from the core 6, and cams 28 on the member 3 towards the end of the inward movement engage cams 29 on the elements 20 to rock them about pivots 21 so as to force surfaces 24 on the elements into sealing contact with surfaces 23 on the edges of recesses 22 in which the elements are mounted. Fingers 14 pivoted at 16 on the member 3 knock off the plate 35 cast in the previous cycle and also engage pins 30 yieldably mounted in the elements 20 to rock the elements and release the projections 26 from the cast plate and move the projections 25 into operative position. The elements 20 are hollow to form water jackets 55 connected to a passage 41, Fig. 5, in a cooling- system for the cylinder 6. Fluid passes through a pipe 36 into a conduit 39 then via the passage 41, either of two branches 42, 43, a semi-circular channel 50 and an opening 46 or 47 into a space 44 or 45 according to which half of the cylinder is in casting position and is discharged via a port 53 or 54 and a pipe 52. Fig. 8 shows a modification in which instead of using the fingers 14 to rock the elements 20, cams 64 are fixed to extensions 60 of the pivot shafts 21, Fig. 2, to engage rollers 65, 67, during the rotation of the cylinder 6 from one casting position to the next. Specifications 577,769 and 578,795 are referred to.

Title: A device for checking longitudinal registration on machines for performing repetitive operations on a continuous band
IPC: B41F13/02
Filed: 1961-05-18
Abstract: 934,728. Automatic alignment control. G. DALL'OGLIO, A. DE MARSICO, and G. CARNEVALI. May 18, 1961 [May 18, 1960], No. 18228/61. Class 38 (4). In a machine for registering multi-colour printing, a number of rollers are geared to a shaft driven by a main motor, the first roller being coupled directly to the shaft, and the other rollers being each coupled through a differential connected to a servomotor for independent rotation of the rollers to correct their respective positions. Reading heads check the relative positions of marks printed on the paper by respective rollers, or a mark printed on the paper is checked against one engraved on a subsequent roller. An impulse generator, coupled to the main driving shaft, is connected to a high-speed electronic counter 10, a reference head 6 and control head 7 supplying pulses to a starting circuit 8 for the counter. The interval between the pulses represents the positional error, and during this interval the counter 10 registers the pulses from the generator 5. The heads 6, 7 are also connected through sign detector 9 to error-correcting devices 11, 12, which are selectively effective in accordance with the sense of the error. Thus, when the counter 10 has finished counting the number of pulses corresponding to the error, one or other of the devices 11, 12 come into operation for correcting the error. A pulse generating device 13 is coupled to the error-correctors 11, 12, and is connected to the counter 10 for stopping the correction device when the correction has reached a value corresponding to the magnitude of the error. The device 13 may either reduce the number counted in the device 10 to zero or it may stop the correction before zero is reached to allow for inertia. In another embodiment, the generator 5 is replaced by a constant-frequency generator the pulses from which being counted during the interval between the pulses emitted by a reference head and a control head, as in the previous arrangement. A third head is placed at a fixed distance from the reference head and reads the same mark. A second counter records the number of generator pulses between the pulses emitted respectively by the reference head and the third head, and a device connected to both counters determines the ratio between the counted pulses and actuates a correction device, such ratio being independent of the speed of the paper.

Title: Microwave apparatus
IPC: H05B6/76
Filed: 1971-06-01
Abstract: 1342672 Microwave ovens GENERAL CORP 1 June 1971 [1 June 1970] 18389/71 Heading H5H In order to eliminate escape of energy from a micro-wave oven if the door is lightly open, the door or its frame incorporates a resonant cavity which effectively short-circuits any escaping wave energy. In one form the door 5 has a metal shield plate 15 which, in the closed position, abuts against a corresponding plate 7 on the oven. This is surrounded by a metal frame 8, the faces 8a, 8b of which provide a stepped formation and of which the face 8a forms a second seal with the inner face of portion 12c of a metal shield member 12 incorporated in the door. A cavity 13, extending around the member 12, is of a depth equal to one quarter wavelength and its upper edge is a further quarter wavelength from the edge 19 of the oven enclosure. The bottom 12a of the cavity is thus one half wavelength from the edge 19 and provides an effective shortcircuit for energy escaping between surfaces 15, 20 if the door is slightly open. As an additional precaution, a wave absorbing insert 11, of rubber loaded with ferrite, may be fitted in a recess 10 in the face 8a. The arrangement is of particular value where the microwave generator is automatically switched off by opening the door of the oven, as it prevents the escape of energy in the interval before the switch takes effect. In an alternative embodiment, see Fig. 4 (not shown), the cavity is incorporated in the door frame instead of the door itself and it is also suggested, see Fig. 3 (not shown), that the metal-to-metal contact between the members 15, 7 may not be essential. In any of the constructions the cavity 13 may be sealed by a cover member of suitable material, to prevent the ingress of dust.
