Patent GB-1145277-A (GB)
Abstract: 1,145,277. Electrical indicating apparatus. SMITHS INDUSTRIES Ltd. Oct. 28, 1966 [Nov. 2, 1965], No.46475/65. Headings G1J and G1N. A pictorial presentation of the location of a moving vehicle is obtained by converting its displacement from a datum position by a resolver controlled by a heading measuring device into N-S and E-W displacements, represented by corresponding voltage tapped off D. C. -fed potentiometers, each potentiometer being connected in a bridge circuit with potentiometers measuring the N-S, E-W positions of a cursor on a map, whereby the cursor can be made to follow the varying location of the vehicle. As shown Fig. 2, shafts 18, 19 are both driven by an odometer 17 geared to the wheels of a vehicle. A resolver 25 controlled by heading unit 22 feeds the N-S component of movement via shafts 26, 28 to produce a corresponding displacement of the slides 29 of a potentiometer 30. Similarly the slides 49 of potentiometer 50 is displaced in accordance with the E-W component of movement of the vehicle. The position of the vehicle is indicated by a transparent cursor 1 Fig. 1 movable in perpendicular directions along tracks 3, 5 over a map 6. Associated with track 5 is a potentiometer 36, and the voltage at its slider 38, attached to the cursor 1, is compared at 43 with the voltage at slider 29, any difference being indicated at meter 12, whereby the cursor can be moved manually or automatically along track 5 in the N-S direction until its position corresponds to the N-S component of the location of the vehicle. The cursor is similarly adjusted in the E-W direction, so that it shows on the map 6 the time location of the vehicle. Facilities are provided for resetting the initial datum position of the vehicle. The apparatus may be used for homing purposes by setting the cursor at a desired location and controlling the vehicle to eliminate the signals on meters 12, 13, or energizing a "barber's pole" type of instrument to indicate the magnitude and direction of heading error Fig. 4 (not shown).

Abstract: 1,229,092. Controlling pump delivery. WHITE MOTOR CORP. June 19, 1969 [Nov. 8, 1968], No. 31142/ 69. Heading F1A. [Also in Division F2] In a hydraulic system for a truck or tractor comprising a pressure-compensated, variable delivery pump, e.g. a radial cylinder pump, driven by the I.C. engine of the truck or tractor, a by-pass valve 10 is connected between the inlet and delivery sides of the pump to by-pass the pump delivery during starting of the engine, thereby reducing the drag torque on the starter. Valve 10 is shown fitted in the pump cylinder block 14, and comprises a valve member 30 biased by spring 40 away from valve seat 25. Under normal temperature conditions, when the engine is started, valve 10 remains open until the flow rate from pump outlet passage 12 to inlet connection 15, via valve member passages 44, 45, valve seat 25 and housing passages 24, 28, is such that the combined force produced by the pressure drop across the fixed orifice 46 and the variable orifice defined by valve closure portion 38 and seat 25, and the impinging of the flow through passage 44 against the transverse wall of passage 45, overcomes spring 40 to close the valve. The valve is arranged to close at an engine speed intermediate starting speed and idling speed. Under subnormal temperature conditions, a latch member 50 is moved into valve member groove 55 by a bi-metallic element 54 to delay closing of the valve until the temperature of the hydraulic fluid has been raised sufficiently by recirculation through the by-pass valve. The valve is arranged to open in response to a drop in system pressure well below normal pressure fluctuations of the system, i. e. when the engine is shut down and leakage lowers the system pressure. Snap-action closing of the valve is provided by the decreasing of the variable orifice defined by valve closure 38 and seat 25 during closing of the valve.

Abstract: 1,264,620. Data processing systems; data storage. INTERNATIONAL BUSINESS MACHINES CORP. 14 Nov., 1968 [28 Dec., 1967], No. 53982/68. Headings G4A and G4C. In a data processing apparatus, a plurality of buses each connect a different one of a plurality of requestors to a different one of a plurality of responders, there being means for repetitively presenting a given address specifying an operation command request to a selected one of the responders from one of the requestors on an interconnecting bus, means responsive to the acceptance of the request by the selected responder for transmitting an acceptance signal to the one requestor on a respective one of the plurality of buses, and means operative upon the receipt of the acceptance signal for causing a single transmission of data signals from the requestor to the responder. Any one of a plurality of processors can present a request signal to any one of a plurality of memory modules, accompanied by a memory address applied repeatedly from a (circular) shift register serially by byte and parallel by bit. When the memory module is free it sends a "request accepted" signal to the highestpriority requesting processor and starts accepting the address bytes and other signals from this processor, inserting the address bytes into a memory address (shift) register. Data is sent serially by byte, parallel by bit, in either direction (depending on whether the processor requests a read or write memory operation) between a (circular) shift register in the processor and a memory data (shift) register in the memory module. Each address and data byte is accompanied by a clock pulse which synchronizes operations in the destination unit, and the first byte of the address (on each repetition) and of the data is accompanied by a start address or start data signal respectively for control purposes. Byte counters are provided in the processors and memory modules for control purposes. Apart from the lines carrying the request signals, each line from a given processor goes to all the memory modules. Apart from the "request accepted" lines, each line from a given memory module goes to all the processors. Alternatively, cross-bar switch means may be provided. Some of the processors may be replaced by channel units. Bytes might have only one bit each.

[Also in Divisions F2 and G2-G3] Original and copy sheets 6, 6a are passed into a copying machine by entrainment between a moving belt 5 and a roller 8. When the leading edge of the sheets trips a microswitch 12, roller 8 is retracted out of contact with the sheets, and at the same time its direction of rotation is reversed. Thus if the trailing edge of sheet 6 has a tendency to curl, as shown, it is straightened by the reversely rotating roller 8. A series of such rollers 8 are provided, of resilient material, and mounted on a common shaft 9. Shaft 9 is drivingly connected to shaft 4, which drives the belt 5, by respective friction wheels 10, 11 on the ends of the shafts, which wheels engage each other as shown in Fig. 4. A belt 16 also connects the two shafts, but in the Fig: 4 position is loose and inoperative. When microswitch 12 is tripped, an electromagnet 13 is energized, which raises shaft 9, and hence wheel 10 is drawn out of contact with wheel 11. Transmission between drive shaft 4 and shaft 9 now takes place via the belt 16, which has been drawn taut (Fig. 5, not shown), shaft 9 now rotating in the opposite direction (see Division F2).
