Title: Improvements in or relating to press button tuned radio receivers
IPC: H03J5/12
Filed: 1939-02-17
Abstract: 525,611. Adjusting tuning impedances. COLE, Ltd., E. K., and KEMP,R. Feb. 17, 1939, No. 5261. [Class 37] [Also in Group XL] In a button-tuned receiver of the type in which the press-buttons move an element of a variable impedance, each button is normally locked against rotations, but when depressed can be rotated to effect continuous tuning of the receiver. Three formers 8, 9, 10 carry the various tuning coils, and spindles 12 carry adjustable cores inside the formers. The spindles 12 are held pressed against a rocker bar 6 by springs at the other ends of the former. Press-buttons 3, normally held in their retracted positions by springs, are mounted on the front of the frame, and a latch bar 14 is provided to hold one button depressed at a time. The actuating rod.5, which is of adjustable length, engages the rocker bar 6 when a button is depressed and so positions the spindles 12 together with the coil cores. Pins C fixed to the actuating rods 5 move in slots in a bracket 4. and when a button is depressed the associated pin co-operates with a plate 16 having cam-slots 17. Sliding motion of the plate 16 causes rotation of the shaft 21 which operates the wave-change switches. This switch can set itself in one of three positions, depending upon the shape of the cam-slot associated with the depressed button. The pivot 7 of the rocker bar 6 is connected by linkwork 22, 24, 25 with a pointer 26, which indicates on a scale 28 the position of the ganged cores and the tuning of the receiver. Thus when a button is depressed, a definite position of the tuning coil cores is effected, the wavechange switch is altered if necessary, and an indication of the tuning is given. Also rotation of the depressed button 3 causes the screw 23 to be advanced or withdrawn, so that continuous tuning of the receiver is possible. When not depressed, rotation of the button is prevented by the binding action of a spring the ends of which move in a narrow portion of the slots in plate 4. When the button is depressed, the spring ends move to a wider portion of the slot.

Title: Improvements in the recovery of diamonds
IPC: B03C7/06
Filed: 1949-02-25
Abstract: 662,463. Electrostatic separators. INDUSTRIAL DISTRIBUTORS (1946), Ltd. Feb. 25, 1949. [March 9, 1948] No. 5266/49 Class 72. In an electrostatic process for the separation of diamonds from gangue, the lower surface conductivity of the diamonds is utilized to bring about physical separation. In one form, Fig. 1, the diamondiferous material is fed through a vibrating feeder 11, heated (e.g., by infra-red elements) at 12, on to an earthed metal conveyer roller 13 which moves the material through an electrostatic field formed between the conveyer roller 13 and a pin-point electrode 14 preferably of positive polarity, A rionmetallic roller 15 which is charged to the same sense as roller 13 attracts the gangue, which has the higher surface conductivity, towards the roller so that it falls in the hopper 18, whilst the diamonds are repelled and fall in the hopper 19. The material may be treated with a mixture of sodium bichromate and sulphuric acid to clean the diamonds and may also be treated with an aqueous solution of “ to 2 per cent common salt to make the gangue more conductive. In a further process in which the round and flat diamonds are separated, Fig. 2, a charge is induced to the diamonds on the conveyer belt 23 by an electrode 26, and round diamonds (viz. those having the smallest contact area) fall into a bin 27, flat diamonds adhere to the belt and are knocked into the bin 31 by a brush 30, the remainder being removed by a scraper 29, falling into the bin 28.

Abstract: 1,141,463. Board game. C. G. ROSTANT. 4 May, 1966 [8 Feb., 1965], No. 5421/65. Heading A6H. Apparatus for playing a board game simulating ground warfare comprises (a) a board representing a battlefield, marked with squares and having distinctively marked in each half thereof a "deployment" line behind which chosen movable playing pieces are placed prior to commencing a game; (b) pieces representing topographic features such as woods, hills, air-strips, valleys and roads to be placed as desired on the board; (c) playing pieces representing tanks, guns and aeroplanes to be moved at will by the players; (d) pieces representing mines, (e) a set of cards for indicating whether "hits" or "misses" have been effected by the movement of the playing pieces and (f) dice to be thrown to indicate whether an attacked playing piece has been destroyed or not. The board is preferably made in two identical halves so that after the opposing players have arranged topographical features on the board the two halves can be separated and the players can deploy the playing pieces, i.e. tanks, guns and aeroplanes in secret. These playing pieces may be moved over a predetermined number of squares in each move, these moves being influenced by the topography of the area i.e. by the disposition of the topographical pieces. When a piece is within firing distance of an enemy piece a card is drawn from the pack to decide whether the piece has been hit or missed; if hit a dice is thrown and according to the number thrown the piece is either considered destroyed and removed from the board or else is undamaged and remains in the game. The apparatus also includes as an optional feature a "campaign" board which comprises a board marked with squares and representing a larger area than the battlefield board which is depicted as a rectangle on it. This "campaign" board may be used in conjunction with the battlefield board.
