Title: Transducer positioning system
IPC: G11B21/08
Filed: 1976-03-29
Abstract: 1508552 Automatic control BURROUGHS CORP 29 March 1976 [28 April 1975] 12581/76 Heading G3N  A servosystem positions a transducer with respect to a disk store comprising a stack of rotatable disks 11, Fig. 2, bearing concentric tracks on which are written, in sectors, servo and work data. The servo data is stored Fig. 3 commencing with sync transition followed by fine position data and coarse position data. The coarse data is recorded in positions in cells A, B, C as manifestations each denoting a binary 0 or 1. A three digit code permits a transfer of a magnetic readwrite head across a maximum of 8 tracks but the number of cells may be varied to modify trackaccess. A coarse servo detector 28 Fig. 7 for use in a system for energizing an actuator positioning a carriage on which is mounted a plurality of heads for reading tracks on a disk stock, comprises a register 35 retaining the current address and a register 37 for a target address whereby, through a subtractor 40, a track accessing value is set in a counter 45. The detected coarse servo data is fed to a de-coder 50 and, in binary form, loaded into a register 52. The resulting servo track identifying data is applied to a comparator 54 together with the servo track data B from a counter 56 holding the current servo-track position at the time the coarse position operation was initiated plus the number of tracks accessed. If A#B during a comparison, showing a further track has been crossed, the counter 45 is decremented and the counter 56 augmented. The count in counter 45 is applied to a D/A converter to derive a coarse position control signal for the actuator, not shown, which reduces in value as the target position is approached. A zero count detector 58 transfers control to a fine position detector 30, not shown.

Title: Digital arithmetic units
IPC: G06F7/50
Filed: 1976-03-31
Abstract: 1522045 Arithmetic units INTERNATIONAL BUSINESS MACHINES CORP 31 March 1976 [1 May 1975] 12968/76 Heading G4A A carry/borrow look-ahead arithmetic unit 10, Fig. 1, comprises a number of digit stages 11-18 and circuitry selecting a variable size group of contiguous stages for operation as a parallel arithmetic unit independently of the non-selected stages. Adders/subtractors are described in which the stages 11-18 can be divided into up to three zones, the positions of the inter-zone boundaries A, B being variable to select the number and size of the zones. In the extreme cases, there is a single zone (zone 2 with A=0, B=7) or two zones (zones 1 and 2 with A#0, B=7, or zones 2 and 3 with A=0, B#7). Inter-zone carries are eliminated and are replaced by external carry-in signals CU, CV, CW and zone carry-out signals CX, CY, CZ so that each zone may operate independently of the other zones and different arithmetic operations may be simultaneously performed in different zones. As shown in Fig. 1 the boundaries are movable in 1-byte steps, but other unit variations are envisaged. Detailed embodiment. Fig. 17, shows an 8-byte carry look-ahead parallel adder in which the carry logic is simplified by the inclusion of byte group carry logic 108, 109 operating on the carry generate G and carry transmit T signals of the byte stages in the associated group to produce combined generate and transmit outputs for the group. Similar grouping between bit stages within each byte stage may also be employed. Division into autonomous zones is effected by switching circuits 120-127 and 130-137 which comprise gates selectively disabled to block the carry transmit signal T from the byte stage 30-37 on the low order (right) side of a zone boundary and gates selectively enabled to pass the carry generate signal G from the associated byte stage 30-37 or, if the stage is the first in a zone, to pass the external carry-in signal CU, CV, CW. The switching circuits 120-127 and 130-137 are controlled by boundary A, B decoders 110, 112 which also control zone carry-out selection gates 162, 164. The carry-in logic 150 supplies the external carry-in CV or CW to the lowest-order byte stage 37 depending on whether or not B = 7, i.e. whether the stage is in zone 2 or zone 3. The boundaries may be set by microinstructions, and a boundary error signal may be produced if boundaries A and B are found, on comparison, to give zone overlap.

Filed: 1949-05-17
Abstract: 659,153. Counting-apparatus. BROCKLEHURST-WHISTON AMALGAMATED, Ltd., and SWINDELLS, E. May 17, 1949, No. 13177. [Class 106 (i)] A thread-counting device comprises a supporting member across which the threads to be counted may together extend in spaced relationship, means holding said threads against said supporting member but adapted to permit them to be slid one at a time along and over one end thereof, a yielding element disposed at one end of said supporting member and adapted to be engaged once by each thread as it is slid over the end of said member so that successive movements are imparted to said yielding element, and a counter actuated by said element. Threads to be entered into a cross-reed 11 are supported by a bar 19, against which they are held by a weight 33. As they are slid off the end of the bar 19, they engage and rock a finger 43 of a casing 42 freely pivoted on a shaft 38 of a counter 31. A pawl 46 mounted on the casing 42 is thus caused to advance a ratchetwheel 39, fast on the counter-shaft, by one step for each thread. The casing is restored after each thread by the weight of the finger 43 which normally projects into a slot 44 in the end of the bar 19. The movement of the finger is limited by a loop 47. The counter and a guide 36 for the threads are secured to a bar 23 pivoted to a head 17, in which the bar 19 is secured, so that the counter mechanism may be swung away from the bar 19 when threads are to be placed over the latter. An adjustable screw 29 cooperates with a surface 27 of the bar 19 to ensure proper co-operation of the parts. The head 17 is clamped to a rod 15 rotatably and longitudinally adjustable in a clamp 16 carried by a loom-entering stand 10 which also supports the cross-reed 11. The counter has a zeroizing knob 37.

Abstract: 595,302. Gas turbines. ENGLISH ELECTRIC CO., Ltd., and WELSH, R. J. July 11, 1944, No. 13211. Addition to 595,297. [Classes 57 and 110 (iii)] [Also in Group XXVII] The plant described in the parent Specification has additional regulating means in which pressure waves delivered by a 'gas generator A act through a pipe 4 and thus to a pipe 7a, and' also through a pipe 4a upon the two sides of a vane 37 normally held in mid-position by springs 39. If the pressure impulse from A, through pipe 4a, arrives slightly before the impulse from the manifold 7, through 7a, the vane 37 will move to the left and move a piston valve 25, to the right just as a piston 19 pumps fluid into a pipe 23. Fluid thus passes through a port 24d and moves a piston 29 to decrease the fuel supply to the generator A, acting through links 32, 34, 35, cam 30 and three-armed lever 15, upon a fuel-inlet valve 5 to slow down the speed of A. If the pressure wave arrives in 7a before 4a, the vane 37 will move to the right and the fuel supply to A, through the valve 5, will increase. An electric switch can take the place of the pump 18 and the vane 37 can operate a switch having a middle '' off" position, the lever 15 being moved electrically. Instead of acting on the fuel supply, the gas generator speed may be controlled by other means as described in the parent Specification.
