Title: Coin controlled apparatus for producing sound records
Inventor: CLARK CHARLES WILLIAM
IPC: G11B19/08
Filed: 1965-03-24
Abstract: 1,147,332. Coin operated recording and reproducing apparatus. C. W. CLARK. 24 March, 1966 [24 March, 1965], No. 12498/65. Heading G5R. An arrangement in which on insertion of a coin of low denomination, a customer can select one of ten sound tracks recorded on tape for play back over a loudspeaker or, on insertion of a coin of larger denomination, can record the selected track on a disc record which is then delivered to the customer. The tape play back arrangement includes a ten track endless tape, a multiple pick up head providing one head for each track of the tape and a control circuit, Figs. 1 and 2 (not shown), by which on insertion of a coin of either denomination the tape drive, sound amplifiers and push button track selection panel are energized. Additionally on insertion of the larger denomination coin the disc record recording apparatus is also energized. The record to be cut is clamped on a turntable 27 by means of an arm 32 and the turntable is rim driven by means of a rubber tyred wheel 36 which also engages a driven shaft 35. A cutting head 44 is mounted on a carriage 46 which is driven along a shaft 47 when the cutting head is in its lowered (cutting) position by means of a follower in the base of the carriage which engages a lead screw 55 rotated via a belt 58 and gearing from the turntable. At the end of the recording period an overdrive arrangement speeds up the rotation of the lead screw to form run out grooves on the record. The cutting head is raised or lowered by a long cam member C which engages a follower at the rear of the carriage and pivots it about its support shaft 47. At the end of the record cutting programme the recorded record is delivered to the output shoot 75 and a new blank is moved from the stack of blanks M to the turntable by means of the large diameter disc 72 which is formed with three circular apertures 73 slightly larger in diameter than the records. The disc 72 is mounted on a shaft 74 and is connected to a second disc 82 which is notched at 120 degree intervals. On completion of cutting the clamp arm 32 is raised, the solenoid 86 is energized to raise the detent 84 engaging one of the notches and the disc is rotated via gearing 79 by a pair of drive wheels which engage the upper and lower surfaces of the disc. At the end of 120 degrees rotation the detent drops into the next notch and the disc drive is discontinued. This 120 degree rotation of the notched disc 82 is also used to return the carriage to its initial position by means of an arm 98 which is pivoted by one of the pins 89 formed on the disc and engages a carriage return thrust rod 101. After initial switch on by insertion of the large denomination coin the record making process is automatic being controlled by the switches M operated by moving parts of the machine.

Title: Improvements in or relating to aerials
Inventor: HOGG RICHARD WILLIAM
IPC: H01Q9/28
Filed: 1949-05-11
Abstract: 675,101. Aerials. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 11, 1950 [May 11, 1949], No. 12622/49. Class 40 (vii). A hollow conical dipole aerial comprises an upper frusto-conical element 4 which is mounted co-axially upon a cylindrical supporting mast 3 with a conical conducting screen 5 extending between the element 4 and the mast, and a lower frusto-conical element 1 which is supported upon the mast by a conducting annular member 2 closing the truncated end of the element 1. The aerial is fed by a parallel-wire feeder or, as shown, by a co-axial feeder 6 passing up the centre of the mast and emerging through a hole 7, one conductor being connected directly to the member 2 and the other being connected, preferably through a condenser 10, to the truncated end of the element 4. The screen 5 may act as a support for the element 4 or, alternatively, the screen may be constructed of thin metal, the element being supported by a further insulating member. A further support comprising a disc 11 of dielectric material may be provided. Also a cylindrical shield 12 of dielectric material may be provided. The position of the screen 5 is so chosen as to balance out the reactive component of the aerial impedance. The arrangement illustrated may be repeated at intervals up the mast to form an array; on account of the screens 5 negligible stray coupling exists between adjacent dipoles. The Provisional Specification also describes a conical dipole aerial having similar upper and lower elements, each having a screen extending from within the element to the mast. The distances of the screens from the mouths of their respective cones differ so as to increase the band-width of the aerial. An alternative arrangement comprises a step in the screen 5, thereby effectively creating in the upper cone two cavities of different dimensions and so increasing the band-width of the aerial. Reference has been directed by the Comptroller to Specification 649,944.

Title: Improvements in or relating to methods of connecting integrated circuit chips to printed circuit boards
Inventor: BINGHAM KENNETH CHARLES ARTHUR
IPC: H05K13/04
Filed: 1969-03-12
Abstract: 1,249,067. Mounting integrated circuits. INTERNATIONAL COMPUTERS Ltd. 23 Feb., 1970 [12 March, 1969], No. 12924/69. Heading B3A. [Also in Division H1] A method of assembling integrated circuit chips 11 on to a printed circuit board includes forming a mask 5 having apertures 8 corresponding to the chip positions, each aperture being provided with two reference edges 9, 10; positioning the mask on the board; positioning a chip in each aperture; effecting relative movement between the board and the chips so that each chip is engaged by the edges 9, 10 and so that contacts on each chip are aligned with corresponding board contacts 4; and making electrical connection between the chip and board contacts. Reference edges 13, 14 of the mask are aligned with marks 6, 7 on the board, the latter being preferably formed at the same time as the contacts 4, and the correct orientation of the chip on the board may be checked by indicia thereon or by the completion of electrical circuits between probes. The apertures 8 are sufficiently large to allow the chips to enter easily and the mask is thinner than the chips so that they stand proud to enable aligning forces 12 to be applied to them. Alternatively the chips are aligned by moving the board and mask relatively to one another. The chips and apertures may be asymmetrical so that chips may be positioned by placing an excess number on the mask and vibrating the board and mask, so that the chips enter the apertures with the correct orientation. The apertures may be of different sizes and shapes so that only the correct chip can be inserted in each aperture.

Title: Improvements in electrical signalling systems
IPC: H04Q1/36
Filed: 1943-08-18
Abstract: 567,590. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and WRIGHT, D. Aug. 18. 1943, No. 13421. [Class 40 (iv)] In an impulse repeater, a rotary stepping switch determines the impulsing speed by timing the first complete impulse (break plus make) and in accordance with its setting adjusts the break periods of the succeeding repeated impulses so that they have a correct break-tomake ratio. The first repeated impulse is given a fixed break period of 55 milli-seconds, which is correct for an impulsing speed of 12 per second. As shown, on the first relapse of line relay A, relay AR operates momentarily in series with a condenser QC and connects up repeating relay PU and relay L, which locks until the end of the impulse train. The switch MS is started and continues by self-interruption. The first repeated break is measured by the release lag of PU, the lower winding of which is shunted by a resistance YA. If the digit is 1, the switch MS returns to normal and produces no effect. For other digits, relay R operates momentarily on the next relapse of A, connecting up PU again and also energizing relay FP, which locks, stops the switch MS and replaces resistance YA by part of a tapped resistance TR determined by the setting of MS. Relay R responds to subsequent impulses, and the relapse of relay C at the end of the train unlocks L and FP and restores the switch MS. Relays Band C are held in series while PU is up. In a modification which compensates for the limited accuracy obtainable with a stepping switch of the standard type, the resistance TR is chosen so that the release lag of PU is somewhat less than it should be for all speeds and a second repeating relay is given a release lag which makes up the deficit. The latter relay is governed by a condenser /resistance timing circuit which is dependent on the speed for the second repeated impulse and on the make period determined by PU for succeeding impulses. Specification 559,539 is referred to.
