Title: Improvements in or relating to magnetic data store devices
Inventor: KEACH ANTHONY ERIC RAOUL
IPC: G11C11/06
Filed: 1965-05-21
Abstract: 1,098,771. Circuits employing bi-stable magnetic elements. GENERAL ELECTRIC CO. Ltd. May 13, 1966 [May 21, 1965], No. 21719/65. Addition to 1,096,307. Heading H3B. The magnetic data storage device described in the parent Specification is modified by the addition of at least one further apertured storage core in the conductive loop coupling the primary apertured storage core to the transformer core, the arrangement preventing spurious outputs from being produced when an unselected storage device in a matrix store is energized by a single selection wire. A total of three storage cores la, 16, 1c are used in each storage device 1-12 in the storage matrix shown in Fig. 1, each device including a transformer core 1d which is coupled to the storage cores by a conductive loop le. A primary storage core 1b is switched if coincident half current read pulses are applied to the associated row and column selection wires 15a-18b, 19a-21b, each selection wire consisting of a pair of series connected conductors such as 15a, 15b threading the primary storage core 1b and one of the further storage cores 1a, 1c. If a storage device is subjected to either a row or a column read pulse alone, the half-current disturbance which causes storage core 1b to induce noise in the conductive loop is neutralized by a like output of opposite polarity produced by corresponding disturbance of a further core la or 1c. Several sense wires such as 13, 14, each corresponding to a different digit position of a stored binary word, are associated with the transformer cores 1d as described in the parent Specification. Half-current switching pulses of opposite polarity to the read pulses are applied coincidently to the row and column wires to restore the matrix to its initial condition. Alternatively, a restoring bias in a further conductor, not shown, may be used, the bias conductor threading all the storage cores. A further alternative is to apply full current switching pulses in turn to the column and row wires, which results in the selected device of firstly cores la and 1b switching but producing no resultant output in the conductive loop, and secondly core 1c switching and producing an effective output. In a modification, two storage cores la, 1b only are provided for each device, in which case noise suppression occurs only if the row wires alone are pulsed. A further modification is the use of four storage cores for each device in a three co-ordinate storage array, the selection wire for each coordinate being threaded through two cores of which one is common to all three wires. The transformer and storage cores are mounted on opposite sides of a substrate 22, Fig. 2, each transformer core 9d being held by two conductive staples 25, 26 to which wires 32, 33 are secured so as to form the closed conductive loop, the storage cores 9a-9c being suspended from these wires. Instead of separate cores, a plurality of apertures in a common block of magnetic storage material may be used.

Abstract: 376,521. Gun mountings. SOC. ANON. DES ANCIENS ETABLISSEMENTS HOTCHKISS & CO., 6, Route de Gonesse, St-Denis, Seine, France. July 30, 1931, No. 21786. Convention date, Aug. 12,1930. [Class 92 (i).] Relates to tripod gun mountings for supporting machine or other light guns either in the ground-firing position, Fig. 1, or in the position for anti-aircraft fire, Fig. 4, the gun cradle 16 and the gun M being trunnioned in the upper carriage 4 which is vertically pivoted to the tripod head 1. According to the invention, the gun in the ground-firing position is removably trunnioned in the upper carriage 4 on an axis which is coincident with the axis of the cradle trunnions and which intersects the gun's axis. Spring catches 20, Fig. 2, permit of readily mounting the gun trunnions M<1> in the ground-firing position, a pin M<2> on the gun stock being then held in a recess 29 on the gun cradle. The gun and cradle can thus be elevated together about their common axis by a screw gear 24. Training is effected by a worm gear 10. Adjustable stops such as 34 limit the training and elevation in sweeping fire. The gun can be readily removed and mounted in trunnion bearings 33 at the upper part of the cradle, Fig. 4, when used for antiaircraft fire. The Specification as open to inspection under Sect. 91 (3) (a) also describes-(1) a pivoted half-nut 26 for readily disconnecting the elevating gear when moving the cradle to the position shown in Fig. 4, (2) a right and lefthanded screw clamp 47 for locking the gun or cradle in elevation, (3) a spring-controlled screw clamp 37 for locking the gun in training, (4) an eccentrically-mounted training-worm 10 which allows of quick or fine training movements. This subject-matter does not appear in the Specification as accepted.

Title: Liquid fuel injection pumps for internal combustion engines
Inventor: KEMP KENNETH ALBERT WALTERS
IPC: F02M41/14
Filed: 1960-06-22
Abstract: 914,532. Fuel injection pumps. C. A. V. Ltd. June, 5, 1961 [June 22, 1960], No. 21821/60. Class 102(1). In a fuel injection pump comprising a rotary distributor body housing at least one transverse piston reciprocated by an annular cam 5, rotation of cam 5 to vary the timing is effected by a piston 1 and piston-valve 7 responsive to fuel pressure from a feed pump. The cam is held in its retarded position while the engine is started and moved to its advanced position after a given engine speed has been attained. The feed pump delivery pressure is dependent on engine speed and acts on valve 7 via passage 8 to move piston 1 against spring 4. At the given engine speed parts 10 in valve 7 are uncovered thereby exposing piston 1 to the feed pump pressure. On reduction of engine speed, fuel trapped by piston 1 returns to the feed pump inlet via passages 11, 12 and 13.

Abstract: 1,216,190. Resolution of amino acids. IMPERIAL CHEMICAL INDUSTRIES Ltd. 29 April, 1968 [15 May, 1967], No. 22455/67. Heading C2C. Resolution of an enantiomorphic mixture of a compound in which an amino group is attached to an asymmetric C atom is achieved by interacting the mixture with a single opticallyactive form of a substitution-inert metal coordination compound give a diastereoisomeric interaction product, selectively removing and recovering the enantiomer which is less strongly held by the metal co-ordination compound and recovering the original metal co-ordination compound. The co-ordination compound is preferably [Co<SP>III</SP>EDTA]- and the resolution is advantageously performed in aqueous solution. The less strongly held enantiomer may be selectively removed by precipitation and similarly the bound enantiomer may be released from the interaction product by precipitation. In an example DL-lysine hydrochloride was treated with [l K Co<SP>III</SP> EDTA] and phosphotungstic aid added to precipitate the unbound D-lysine, which was recovered from this precipitate by treatment with barium hydroxide.

Title: Improvements relating to binary register units, especially for shifting registers
Inventor: INGHAM WILLIAM ELLIS
IPC: G11C19/28
Filed: 1953-08-15
Abstract: 763,447. Pattern movement stepping register. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Aug. 6, 1954 [Aug. 15, 1953], No. 22553/53. Class 106 (1). A binary register unit, suitable for use as one stage of a shifting register, comprises a bistable device, a monostable device, means for applying shift pulses to said devices, and a source of conditioning signals coupled to said monostable device and a coupling from said monostable device to said bistable device so that the bistable device can be switched to either of its states in response to a shift pulse, in dependence upon the conditioning signal applied to the monostable device. A short positive shift pulse applied from lead 10, Fig. 1, to the emitter of a transistor 1 (the monostable device) via a condenser 18 and rectifier 17, and also to the base of a transistor 2 (the bistable device) via a rectifier 11, tends to set the transistor 1 " on " (high current flow) and to set transistor 2 " off ". However the voltage of the shift pulse is so chosen that the pulse is only effective to set transistor 1 "on" when a positive conditioning voltage is applied to the " anode " side of the rectifier 17 via a resistance 19. Every time transistor 1 goes " on," its collector lead, which is joined to the emitter of transistor 2 goes more positive and sets transistor 2 " on," the inductance 20 being such that transistor 1 stays " on " for a period longer than the duration of the shift pulse. Thus by taking an output lead 22 from the collector of transistor 2 a number of these units can be connected in cascade to form a shifting register, the voltage on lead 22, constituting the conditioning voltage for the next unit, being more positive when transistor 2 is " on ". If the register so constructed is considered to consist of a register proper (the bistable transistors) and a temporary register (the monostable transistors) the shift of a number in the register then occurs in three stages, a first stage, initiated by a shift pulse, in which simultaneously the registered number is trans-, ferred to the temporary register advanced by one stage and the register proper is cleared, a second stage, occurring immediately after the shift pulse ceases, in which the number is transferred from the temporary register to the register proper, and a third stage in which the temporary register automatically clears itself, the timing of this stage depending upon the time taken for the monostable transistors to return to their stable states.

Filed: 1920-07-30
Abstract: 170,684. Goold, L. W., (Colmar Burner Co.). July 30, 1920. Fluid-actuated valves.-In a vapour burner 1 a thermally controlled valve 8 prevents the passage of the fuel oil from a hand valve 7 on the supply pipe to the vapour generator 12 when the vapour generator is below a prearranged temperature. The valve 8 comprises a body 14 having inlet and outlet fuel connections 9, 10 the outlet fuel passage leading from an opening 17 in an internal projecting arm 16. The opening 17 is controlled by a needle-valve 29 on a piston 26 pressed by a spring 32 against a diaphragm 24 arranged between a cap 21 and a coupling 20 on the valve body. A nipple 22 on the cap 21 carries a tube 33 which extends parallel to the generator preferably above the burner openings 5 and is coiled around the discharge end of the generator. An aperture 23 in the cap 21 connects the tube 33 with a chamber 25 formed between the diaphragm 24 and the cap 21. The tube 23, nipple 22 and the chamber 33 are filled, preably, with mercury which, when the vapour generator is at the pre-arranged temperature, expands, and acting through the diaphragh 24 and piston 26 moves the needle valve 29 from its seating in the opening 17, thus permitting the passage of the fuel. The needle valve 29 is adjustable in the piston 26 on unscrewing a plug 19 in the valve body so that the pre-arranged temperature may be adjusted.
