Abstract: 719,216. Radio receiving apparatus. PYE, Ltd. April 24, 1952 [Jan. 24, 1951], No. 1840/51. Class 40 (5). [Also in Group XXXVI] A tuning device for selecting any one of a number of channels in, for example, a television receiver comprises two parallel sheets, of which one at least is made of insulating material, the sheets comprising a plurality of groups of aligned apertures with which are associated, or which serve as, conducting contact sockets, whereby by inserting conducting pins or the like through the two sheets, the sockets of one sheet may be selectively connected with those of the other sheet, the sockets on one sheet being connected to preselected inductances or parts of inductances while at least some of the sockets of the other sheet are connected together. In the embodiment illustrated, a metal sheet 1 and an insulating sheet 2 are arranged parallel to each other and are spaced apart by a sheet of insulating material 7. Apertures 9 in the sheet 1 are aligned with corresponding apertures in the sheet 2, these latter apertures being fitted with contact sockets 4. A tapped inductance 5 is connected as shown to the sockets 4 of each vertical column of apertures and is connected in series with a further inductance 6. Thus by inserting metal screws 8 through the apertures of any one horizontal row, values of inductance are chosen so as to tune the receiver to a corresponding one of five channel frequencies. The three vertical columns of apertures 9 correspond to the tuning of the local oscillator and of two band-pass circuits, the inductances in which are all returned to earth. The tuned aerial circuit is not earthed, and accordingly the sheet 1 is provided with a further set of larger apertures 9a so that a pin passed therethrough does not make contact with sheet 1. The aerial input is connected to socket 10 and thence through coil 11 to the lead 12, the other end of which is provided with a plug 13 which is plugged into the appropriate aperture 9a to make contact with a corresponding contact socket on the rear sheet 2. The aerial circuit is screened from the remaining circuits by a metal screen 18. In a modification (Fig. 4, not shown), the screws 8 are replaced by a single three-pin plug. In a further modification (Fig. 5, not shown), both sheets are made of insulating material and comprise aligned contact sockets, some at least of the sockets of one sheet being connected together.

Title: Improvements in or relating to power presses
IPC: B30B15/00
Filed: 1965-01-18
Abstract: 1,137,674. Mechanical presses. COWLISHAW WALKER & CO. Ltd., N. H. POUT and D. HOLDING. 17 Jan., 1966 [18 Jan., 1965], No. 2178/65. Heading B5F. [Also in Divisions B3 and G3] . A power press having opposed tool carrying platens, which are movable towards and away from one another in the cyclic operation of the press, has one of the platens adjustable to suit a range of tools, the adjustment being effected in dependence on the output of a comparator responsive to a coded signal in a memory device, representative of the existing adjustment relative to a datum, and a coded signal, representative of a desired adjustment relative to the datum. As shown in Fig. 8, a reciprocated connecting rod 19 is pivotally connected to a member 20 to impart a vertical thrust. The member 20 is threaded on its lower portion and engages a nut 21 having worm teeth on its periphery. The nut is free to rotate about the axis of the member 20 but is constrained vertically, so that rotation of the nut causes relative motion between the member 20 and a tool-carrying slide 22 to adjust the slide working face with respect to the lower platen, not shown. The nut 21 is rotated by a worm, not shown, driven by a motor 24. The slide adjustment is effected at a tool change by a programme control system, Fig. 11, wherein a card is inserted in a reader 33, and the digitally coded read signals are compared with digital coded signals stored in a memory of a comparator 35, representative of the actual adjustment with respect to a datum of the slide. The comparator output actuates a reversing contactor 30, 31 controlling the slide adjusting motor 24. The movement of the motor causes a vane geared to the motor to actuate a proximity switch, pulses from which are stored in the memory and the motor is stopped when the comparator output falls to zero. A tool change cycle comprises bringing the press to rest near top dead centre, a switch 32 is then moved to auto and an initiation button 38 depressed. The press slide then descends to rear bottom dead centre where it is stopped by a switch 40. The tools are then changed and a card inserted in the reader. Manual control is effected through the switch 32 and pushbuttons of contactor 30, 31. It is stated that a plurality of presses can be controlled from a common point and that the cards can be replaced by a magnetic tape.

Title: Electric signal storage devices
IPC: H01J29/44
Filed: 1949-01-28
Abstract: 675,094. Cathode-ray tubes. WESTERN ELECTRIC CO., Inc. Jan. 28, 1949 [Jan 29, 1948], No. 2410/49. Class 39 (i). [Also in Group XL (b)] A storage device comprises a target in which a layer of electrically insulating material exhibiting electron bombardment induced conductivity is enclosed between conducting surfaces and a direct potential is applied between the conducting surfaces during the application of the storage signals and the simultaneous bombardment with electrons. The storage tube comprises an electron gun 13 comprising a cathode 23, a control electrode 24 and first and second anodes 25, 26. The deflecting plates 14, 15 are fed by balanced sweep circuits comprising condensers 40-43 and resistances 44, 45. The target comprises an insulating material 16 such as diamond, zinc sulphide, magnesium oxide, silicon carbide or stibnite enclosed between two thin metal plates or layers 17, 18, e.g. of gold, silver, platinum or aluminium. If diamond is the material it is present as a thin plate or as small chips or dust. A commutator or controlling switch 19 connects plate 18 alternatively to the signal source 20 and to a signal utilization circuit 22. A potential of 1000 to 10,000 volts relative to the cathode is applied to the final anode 26 and a wall coating 27. The high velocity beam scans the target when it is connected to the signal source 20 and traps in the material a charge proportional to the signal intensity at impact. This charge is released on the second scan due to the evenly induced conductivity and gives a signal in the utilization circuit 22. In an alternative arrangement, the signal is applied to the control electrode and modulates the scanning beam, the switch on a succeeding scan breaking the signal connection and simultaneously establishing connection between the metal plate of the target and the utilization circuit. Two such devices may be used in tendem to delay a video signal by a frame time, the connections to signal and utilization circuit being alternate and the commutator and sawtooth sweep circuits synchronized. Specifications 676,411 and 676,425 are referred to.
