Abstract: 1,128,576. Electric digital calculators. INTERNATIONAL BUSINESS MACHINES CORP. 29 July, 1967, No. 34961/67. Heading G4A. In a multi-word data store capable of performing logical operations, bit conductors are each connected in common to the bit storage devices occupying corresponding bit positions in each of the word locations, and a plurality of majority logic gates each connect a different pair of adjacent bit conductors and produce a signal on one of the pair when the signal level on the other of the pair exceeds a threshold. Correspondingly - positioned bits of two words read simultaneously from respective rows of a matrix store are added on the column read-write lines. If the sum on a given column line exceeds 1, a threshold (majority logic) gate respective to the column adds 1 to the adjacent column line. In this way carries can be propagated during addition of two words (with end-around-carry in the case of twos-complement subtraction). After carry propagation, the sum (or difference) of the two words is obtained by a level discriminator circuit which in the case of each column line, produces a 1 output if the signal on the line is 1 or 3. Fig. 3 shows two words of the store utilizing cross-coupled pairs 6 of two-emitter transistors, each threshold gate being a transistor longtailed pair 7. The sum may be obtained, after carry propagation as above, without use of the level discriminator circuit, by a sequence of complementings, storings, majority operations (using the threshold gates and reading out three words simultaneously in each case) and shift (using an external shift register), which is described.

Title: Preventing or reducing stalling of the early rows of axial-flow compressor blades of gas turbine engines
Inventor: THOMAS ALBERT
IPC: F04D29/52
Filed: 1953-12-23
Abstract: 762,883. Gas turbine plant; axial flow compressors. ARMSTRONG SIDDELEY MOTORS, Ltd. Dec. 3, 1954 [Dec. 23, 1953], No. 35692/53. Classes 110 (1) and 110 (3). [Also in Group XXIX] A gas-turbine plant with an axial flow compressor has a plurality of overlapping shutters pivotally mounted at their upstream ends upstream of the compressor and resiliently biased against the direction of the air. stream so as to extend into and blank off an inner annular por. tion of the compressor; the shutters being movable against the bias in response to increasing engine speed. The axial flow compressor of a gas-turbine engine has a number of overlapping pivoted arcuate shutters 10 disposed so that their downstream ends, in the inoperative position, are adjacent the inner ends of compressor inlet guide vanes 12. In this position, the shutters also form a continuation of the inner wall 13 of the intake. The shutters 10 are pivoted to the compressor casing by pins 16 and beneath the shutters a stationary guard 19 is provided to prevent any parts which may become detached entering the compressor intake. The guards are arranged in groups of three between the aerofoil struts 9. The central shutter has its pivot pin 16 arranged normal to the radius of the compressor casing. The two outer shutters have their pivot pins set at a small angle to the normal to the radius of the compressor casing so that the outer edges of the shutters are maintained as close as possible to the struts 9 during operation of the shutters. A piston 21 slidable in a cylinder 22 is attached to each shutter by a link 21a. The piston 21 is urged in one direction by three coaxial coil springs 24, 25, 26 so as to cause the shutters to extend into the airstream. Oil under pressure is fed into the other end of the cylinder. This oil is supplied from an accumulator 29 and governor-operated valve 31. The governor-operated valve 31, Fig. 4, comprises engine-driven governor weights 37 which move through an abutment 40 a shaft 42 against the action of a spring 41. The shaft 42 moves a valve member 43 which is slidable in a spring- loaded follow-up piston 44. The arrangement is such that for each engine speed, there is a particular pressure in the outlet pipe 27. This pressure is transmitted to the piston 21 so that for each speed there is particular position of the shutters 10. The strength of the springs 24, 25, 26 is so chosen that at all speeds below a predetermined speed the shutters 10 are held in their operative position at approximately 35 degrees to the longitudinal axis of the compressor. As the speed rises above the predetermined value the shutters are gradually retracted. In the Provisional Specification an arrangement is described for operating the shutters by means of a jack and toggle links. Reference has been directed by the Comptroller to Specification 702,266.

Filed: 1920-12-21
Abstract: 155,756. Krupp Akt.-Ges. Germaniawerft, F. July 15, 1918, [Convention date]. Loading-appliances.-Relates to pneumatic ammunition hoists of the kind having a charging tube F which can be swung beneath a hoisting tube A, and consists in employing the pneumatic pressure to force the charging tube against the hoisting tube to make a tight joint. In the form shown in Figs. 1 and 2, two charging tubes F are loosely mounted on horizontal trunnions f<1> on a frame D which is adapted to swing on a vertical axis E to bring one or other of the tubes F beneath the tube A. On raising the controlling piston-valve L against the action of a spring T, air under pressure from a reservoir P first passes by pipes 7, 1 to a cylinder J to admit pressure below a ram H to force the tube flanges a', f<2> into contact and form a tight connexion between the pipes 5, 5<1> which supply air beneath the hoisting piston G. As the valve L is further raised, the air passes by pipes 6, 5, 5<1> to the space below the hoisting piston G to force the ammunition upwards through the tube A. When the unloading position is reached, air is exhausted through a slot a', the piston comes to rest on a stop lever 0, and a lever M is meanwhile rocked to open a valve N to admit pressure by pipes 3, 4 to the space above the valve L. The resulting downward movement of the valve L allows the cylinder J to exhaust through pipes 2, 8 and cuts off the pressure supply to the tube A. On operating the lever 0, the piston G falls by gravity and the air imprisoned in the tube F brings it gently to rest. A modified arrangement is described in which the valve L is replaced by a number of valves operated in succession by cams to ensure the desired sequence of operations.
