[Also in Division G1] For deriving a signal indicative of the operational state of a piston-cylinder ram 4 for advancing a mine conveyer 2, an adapter 1 housing a beam switch assembly 15 is secured to the conveyer and is pivotally connected to the ram 4. The switch assembly comprises a U-shaped stress member 31 of which one limb 32 is fitted with screws 33 which at predetermined loads applied to the stress member 31 make or break contact with micro switches 34 mounted on the opposite limb 35 which is rigid with the housing 7 of the adapter. A steel ball 16 allows for misalignment between the switch assembly 15 and the piston rod of the ram 4. Thrust from the ram is transmitted through the switch assembly 15 to the conveyer through the housing 7. When a number of advancing rams are used each switch assembly may control a signal of a particular frequency and an operator at a remote indicator panel can determine the state of the hydraulic pushing systems along the mine face. The electrical monitoring arrangement may be replaced by hydraulic, pneumatic or electromagnetic radiation or acoustic arrangements.

Abstract: 1366872 Function generators; waveform generators MARCONI CO Ltd 26 Aug 1971 [15 Oct 1970] 49437/70 Headings G4G and G4H [Also in Division H4] An approximation to a sine wave is produced from a digital output by weighting and combining n equal-amplitude rectangular waveforms where n is 2 or more, the waveforms exhibiting respectively during a time 0 to # (e.g. over half the period of the resultant sine wave), changes in the same direction at times 0, #/2n, 2#/2n, 3#/2n...and changes in the opposite direction at times #, (#-#/2n), (#-2#/2n), (#-3#/2n) ... The drawings show the waveforms for n = 4 (Fig. 2) and the resultant stepped waveform (Fig. 3) which is produced when the waveforms are weighted according to the amplitudes shown and then combined. The stepped waveform may be expressed as a Fourier series which is given in the Specification. The waveforms may be synthesized in a logic circuit 4 (details not described) fed by the four most significant outputs of a 13-bit counter 2. The waveforms A, B, C, D are weighted by the resistance network R1, R2, R3, R4 and the resultant stepped waveform smoothed by a first order filter 6, R6, C1 and then by a second-order filter 7, R8, R9, C2, C3 which has a maximally-flat characteristic. A clock 1 drives two 13-stage counters 2, 3 the stages of the second counter 3 being fed from an encoder 14 which encodes the angular position of a rotating aerial 15. The outputs of counter 3 are connected to an AND gate 10 and, with the interposition of inverters 12, 13 connected to the two most significant stages, to a further AND gate 11. The second counter 3 is connected to be re-set by a third AND gate 8 having inputs fed from the outputs of the first counter 2. The outputs of AND gates 10, 11 actuate sampling switches 17, 19 which connect holding circuits 18, 20 to the output of the synthesizing circuit In order to prevent the counter 3 from being reset when any digit from the encoder 14 is changing, the least significant input to the counter is used to trigger a pulse generator 9 which emits a short pulse used to inhibit the gate 8.

Title: Data transfer system
IPC: G06F11/10
Filed: 1963-12-17
Abstract: 1,018,763. Data transfer systems. INTERNATIONAL BUSINESS MACHINE CORPORATION. Dec. 17, 1963 [Dec. 24, 1962], No. 49683/63. Heading G4C. A data transfer system which may be a synchronizing gate circuit for bytes read from magnetic tape comprises a character gate which is opened after a first or second time interval in dependence on a parity check on the byte. The first time is such that all or all but one bit of a skewed byte, received in parallel, will have arrived at the gate. The gate is closed if a parity check indicates that all the one bits have been received, otherwise the gate remains open until the last bit is received. In one embodiment the bits read from a tape 10 are applied to sensing units 14a-14n which may be as described in Specification 875,694. The units set corresponding triggers 16a-16n which provide outputs through normally closed AND gates 21a-21n to output triggers 23a- 23n. The outputs of the triggers 16a-16n also pass to a vertical redundancy checker 18 which sets a trigger 40 after a time when at least all but one of the bits of a byte have been received. The trigger 40 is set to bring up either output C or C in accordance with whether a word having the correct parity has been received at this time or not. This output opens one or other of two gates 41, 42 to gate one or other of two differently delayed pulses RC-6, RC-8 through an OR gate 43 to simultaneously open the AND gates 21a-21n. Thus the AND gates are opened either when all but one of the bits should have been received or at a time all bits of a byte have been received. In a modification (not shown) if the parity is not correct after the first time the gates 21a-21n are opened as soon as the last " one " bit is received. Dropouts could be eliminated as described in Specification 1,018,762.

Abstract: 1,170,587. Multi-processor computer systems. GENERAL ELECTRIC CO. 16 Nov., 1966 [16 Nov., 1965], No. 51392/66. Heading G4A. Provision is made in a multi-processor computer system for communication between individual processors of the system in such a way that neither processor in any communication link is required to halt to complete the communication and the receiving processor is not required to suspend its current operation. As shown, a computer system comprises three general purpose data processors 10, 11 and 12, an input/output processor 30 (each processor being provided with internal storage means, not shown), data storage means 20-26 and a control unit 32. Each processor has an area of or more of the storage means 20-26 allotted to it for communication purposes. When a a first processor, say processor 12, wishes to supply information to a second processor, say processor 30, the first processor 12 sends to decoder 34 in control unit 32 the identity of the second processor 30. Decoder 34 then sets the signal flip-flop 40P corresponding to the processor 30 and also establishes a path to the storage area allotted to the second processor 30 whereby the first processor 12 may transmit thereto the data signals it wishes to communicate. The set flip-flop 40P causes a corresponding flip-flop 35 in the processor 30 to be set and when this processor reaches a suitable point for interrupting its programme, the data stored in memory 20 is transmitted thereto by way of lines 93, 94, and the flip-flops 35, 40P are reset. This last transfer may be under the control of unit 32. The data transferred may be an input/output instruction.
