Title: Improvements in or relating to memory systems
IPC: G11C15/06
Filed: 1964-12-16
Abstract: 1,072,629. Associative memories. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 16, 1964 [Dec. 16, 1963], No. 51217/64. Heading G4C. Individual means are associated with each set of like-ordered bit positions in registers of a memory to specify range and field relationships used during interrogation. The associative memory described uses cross-film and in-line cryotrons and comprises a number of word registers, each bit storage circuit in each having three possible states (0, 1, nothing) and having an associated bit comparison control circuit. Each set of corresponding bit positions in the registers (one position from each register, per set) has an associated input switch settable to 0, 1 or M used during interrogation and to specify bits to be written in, position M being used for masking during interrogation. Each set of corresponding bit comparison control circuits (one from each register, per set) has an associated range switch settable to H, L, E or N meaning high, low, equal or don't care, and an associated field switch settable to AND, OR or N. During interrogation all registers are interrogated simultaneously to see whether they satisfy data specifications set up on the input, range and field switches. As an example, if the switch settings were as follows Bit position 123456789 Range switches NNENNLNHN Input switches 10111001M Field switches NNANNANAN where A means AND, then a register would satisfy the specification if positions 1, 2, 3 stored data equal to 101, and positions 4, 5, 6 stored data less than 110, and positions 7, 8 stored data higher than 01. During interrogation, each register receives current from an associated interrogation control circuit and the bit storage circuits and bit comparison control circuits of the register route this current to set a select control circuit associated with the register to 1 or 0 depending on whether or not the specification is satisfied for that register. The registers satisfying the specification can then be read or written into in turn. Each register may have a vacancy bit position, specifying whether the register contains information.

Title: Transmission systems and methods of festing the same

Filed: 1971-11-04
Abstract: 1358910 Testing unattended repeaters WESTERN ELECTRIC CO Inc 4 Nov 1971 [10 Nov 1970] 51313/71 Heading H4R Iu a digital transmission system utilizing unattended repeaters each of which incorporates a filter for responding to one particular test frequency out of a plurality of test frequencies injected into the system, the repeaters are arranged in groups each of which groups is separately interrogatable so that repeaters in different groups may be allotted the same test frequency. The filters are each coupled to a respective amplifier in a common test line carrying D.C. feed for the amplifiers. For the case where there are two groups of repeaters, the polarity of the D.C. feed may be used to determine the group of amplifiers, and hence of repeaters, which are to be the subject of a test. The test signals may comprise pulse patterns that have fundamental frequencies corresponding to the various filter frequencies. In one such system each ingoing repeater is paired with a respective outgoing repeater and each pair is coupled via a filter to an amplifier in the test line 116. The outputs of the amplifiers 118-121 associated with one group of repeaters are coupled to one wire of line 116 and the outputs of the amplifiers 122-124 of the other group are coupled to the other wire of line 116; the amplifier circuits (Fig. 2, not shown) are arranged such that with one D.C. feed polarity on line 116 amplifiers 118-121 are inoperative and amplifiers 122-124 are operative and with the reverse D.C. feed polarity on the line the converse situation applies. The east-west repeaters are tested from office B in two groups and the west-east repeaters are likewise tested from office A, detecting means 173, 163 being used to identify a faulty repeater from the frequency signals received on line 116. The line 116 may be provided with repeaters (Figs. 3 and 4, not shown) which employ relays energized by the D.C. feed voltage to switch in amplifiers corresponding to the required direction of transmission on test line 116, the repeater also being arranged to supply a D.C. feed signal of the correct polarity to amplifiers of the same group situated beyond the repeater.

Abstract: 1,169,059. Control of A.C. motors. HOLZERPATENT A.G. 10 Nov., 1967 [24 Dec., 1966], No. 51339/67. Heading H2J. [Also in Division G3] A laundry machine is driven by a pole-change motor having low-speed and high-speed windings for washing and spinning respectively, the washing speed being further reduced by an electronic regulator. The motor 1 has windings 2, 3 corresponding to the different pole-members, the electronic speed regulator 6 being placed in circuit by way of programme switches 4, 5. A tachometer generator 7 supplies signals to the regulator 6 which also receives a reference voltage from a voltage divider 9-11 associated with programme switches 12, 13. The motor is operated at the spinning speed when switches 4, 12, are closed, operation at lower speed being provided by closure of switches 5, 13. When the tachometer voltage exceeds the reference voltage, transistor T3 is blocked whilst transistor T2 becomes conductive, whereby transistor T1 is blocked to interrupt the supply of triggering signals to the power semi-conductor device 14 in series with the motor. The transistor T2 is blocked and the transistor T3 becomes conductive if the tachometer voltage drops below the value of the reference voltage. The transistor T1 then becomes conductive so that the device 14 resumes operation.

Abstract: 1,133,574. Crushing rock. S. MARUTA. 6 Dec., 1965 [14 Dec, 1964], No. 51680/65. Heading B2A. A rock crushing apparatus comprises a bearing frame body 38, Fig. 4, movable along guide surfaces of a guide body 36 supported by lever arms 12 so as to be rotatable with the frame body 38. The frame body 38 is resiliently hinged by springs 60 in a striking direction. A drill 78 is reciprocable in a rotary frame fixed to the frame body 38.

Supporting frames 30, Fig. 3, are seamed to the ends cf lever arms 12, and are formed of pieces 31, 32. The guides 36 rotate in annular recesses 35, Fig. 4, in the frames 30. By rotation of the guides 36 frame body 38, which is supported by the bearing hubs 39, Fig. 1, in apertures 37 is rotated, and the rotary frame 55 secured to the frame body 38 is rotated, and advanced by the springs 60. When a shaft 63, Fig. 6, is rotated by a motor 72, Fig. 3, the hammer 68 and balance weight 71 are rotated. The frame 55 is supported by the guides 36 which are mounted on the levers 12 which are themselves mounted on .the body 1 so as to be free to rotate. The drill thus strikes in all directions and crushes the rock.
