Abstract: 1,205,305. Automatic exchange systems. SIEMENS A.G. 18 Oct., 1968 [19 Oct., 1967], No. 49395/68. Heading H4K. The control of individual equipments, such as switching networks AF, is effected from a common control, such as the duplicated processor ZS1, ZS2, with programme stores PS1, PS2, and data stores ZJS, the common control transmitting and receiving data in series or series parallel mode to and from buffer/recoders AS, the transfer of data at a slower rate between the buffer/recoders and the associated individual equipments being effected in parallel mode. The reduced cabling required for series mode data transmission is of advantage when the processor controls remote equipment such as the switching network AFF, each such remote equipment having data sets such as D1, D1<SP>1</SP>, for connection to the local transmission bus U2 which serves networks AF1 to AF11 direct. The buffer AS associated with each network AF communicates in parallel over buses such as U11 U1F, with the control circuits ST of individual switch frames and with local and other-exchange relay sets VS, RS, and with dial signal receivers WS of each network. The networks are such that all inlets and outlets of equipment for establishing a connection as well as all lines and trunks are connected to A-stage inlets. The local networks are aggregated by ZLC links across C-stage outlets. Preferred subscriber groups may be served by one or two stage switches such as STt and KGV. The buffers on standby are in a ready to receive state and can be in a state of waiting to send or a blocked state. Messages comprise a set of equisized sections the first of which indicates the length of the message, the second indicating the address of the equipment to which the message relates and the following sections to a maximum of four concern the work function involved. The buffers are addressed in turn by the processor to establish requirements, addressing being effected over a special address bus or over the common data bus U2. On receipt of each data section the processor reverts an acknowledgment signal which advances a distributer in the buffer where the blocked state is entered into until a new section is compiled for transmission.

Title: Improvements relating to Starting Devices for Diesel Engines
IPC: F02B3/06
Filed: 1967-11-03
Abstract: 1,176,155. Starting prime movers. DAIMLER-BENZ A.G. 3 Nov., 1967 [5 Nov., 1966], No. 50125/67. Heading H2H. [Also in Division F1] A starting arrangement or a diesel engine comprises a manually operated, spring returnable rotary switch having a plurality of operating positions, movement of the arm of the switch from the engine pre-heat position to the engine starting position being inhibited by a stop until a predetermined pre-heat time has elapsed. A rotary switch 12 has a manually operable arm 10 movable between positions O, I, II, III and returnable to the "OFF" position shown by a spring 14. Movement of the arm 10 to position I supplies various ancillary loads as indicated by a lamp 24. Further movement of the arm 10 to position II, the pre-heat position, supplies a number of pre-heaters 36, the arm 10 being held in position II by a stop device 42 which device prevents movement of the arm to position III, the starting position. Simultaneously with the heating of the pre-heaters 36, the heater of a bimetal switch 40 is heated, the switch 40 being situated in the coolant of the engine. When the engine reaches its operating temperature contacts 44 of switch 40 close to energize a relay 46 thereby closing its contacts 56. Closure of these latter contacts energizes the coil 62 of the stop device 42 whereupon the armature 64 is retracted, releasing the arm 10 which is returned by the spring 14 to the OFF position. The engine operator now has a limited period within which to move the arm 10 through position II into position III thereby closing contacts 68 since contacts 44 have remained closed and relay 46 and stop device 42 are energized as soon as the arm 10 reaches the switch select 26. Closure of contacts 68 then energizes locking device 84 and electromagnetic device 80 so that a rod 82 moves into position to supply fuel to the engine with simultaneous energization of relay 74 whereupon motor 76 is energized to start the engine. The arm 10 is moved into position O to stop the engine, in which position electromagnetic device 90 is energized to move the rod 82 to its fuel cut-off position.

Title: Improvements in Control Circuits.
Inventor: PLUMMER DEXTER ROBERT
IPC: G05D3/14
Filed: 1967-11-03
Abstract: 1,197,618. Electric correspondence control. RANK ORGANISATION Ltd. Oct. 29, 1968 [Nov. 3, 1967], No. 50162/67. Heading G1N. A position-control servo is arranged so that a demanded change in position or setting of an actuator, 4, is achieved in a predetermined time. A demand-unit, 20, produces a voltage which is combined in a resistor network 22, 23 with the inverted form of a position feedback signal from a potentiometer 12 coupled to the actuator, 4, a reversible electric motor, inversion having been effected in an integrator circuit 36. An integrator 14 produces a control signal which is combined via resistors 16, 18 with the position feedback signal and, via a resistor 7, with a velocity feedback damping signal from tachogenerator 5 coupled to the motor. The resultant signal being fed through an amplifier 10 to drive the motor which controls the position of a camera 6. A timer 52 is energized by a change in demand and simultaneously a relay 50 causes the arm 30 of a switch 32, through which the position feedback signal is fed to the integrator 36, to change from a position NC to one No. Thus with the system at static equilibrium and the output of the demand unit at + V A  volts, switch arm 30 is at position NC, the position feedback signal is + V A  volts and the integrator 36 output is - V A  so the input to the integrator 14 is zero. The output of the integrator 14 is maintained then at the value last integrated i.e. - V A  volts which is balanced by the position feedback signal to give zero input to the amplifier. Now assume a demand signal change to + V B . The timer 52 is initiated and the switch 32 operates so that the input to the integrator 36 is zero and the output is maintained at - V A  volts thus the input to the integrator 14 is now V B -V A  volts i.e. the demanded change. The output of the integrator changes substantially linearly to - V B  in a time determined by the product of the values of resistance 24 and capacitor 15. At the end of this time interval the timer 52 switches off causing the switch arm 30 to be reset to the NC position. The input to the integrator 14 is again zero and the system is in static equilibrium at its demanded position or setting. In a modification, for controlling a zoom lens, the integrator 14 is modified or replaced by a function generator to provide a control signal which varies non-linearly with time in a required manner. Another embodiment replaces the timer with a null detector to determine when the demanded position has been reached.
