A multi-contact single-pole switch of the slider and contact stud type is arranged so that switching is effected without any break or overlap by connecting the input terminal A of the switch to the moving contact 303 of a flip-flop relay 30 whose fixed contacts 304, 305 are connected to conductive tracks 52, 53 associated with parallel rows of output studs 31 . . . 37, 32 . . . 38 through sliders 49, 50. The rows contain equal numbers of studs staggered by a halfpitch in relation to one another, and a third row of studs 40 . . . 47, alternately aligned with the studs 31 . . . 38 and equal in number thereto, is associated with a track 51 through a slider 48, the sliders 48, 49, 50 being aligned and rigidly connected together. The odd studs 41 . . . 47 are connected to a winding 301 of the relay 30 and the even studs 40 . . . 46 to a winding 302, these windings being connected to one pole of a battery 39 whose other pole is connected to the track 51. In operation, passage of the slider 48 from one stud to another reverses the stable position of the relay 30 and connects the input A to a stud in one or other of the rows 31 . . . 37, 32 . . . 38, depending on the position of slider 48 and its direction of movement. For slider positions intermediate of the studs 40 . . . 47 the connection of input A is the same as that for the preceding stud, due to the action of the relay 30. In a modification for a three-pole switch, Fig. 4 (not shown), the relay has three sets of contacts, the moving contact of each being connected to a corresponding input terminal (one per pole) and the fixed contacts being connected to the tracks (three per row) associated with the output studs. Two additional sliders are provided per row for the additional tracks and are aligned in pairs, the aligned sets of sliders being spaced from one another by one or more pitches of the studs 40 . . . 47. The contact studs may be disposed on a cylindrical surface and the invention may be applied to a distributer having the form of a collector of a rotating electric machine, the relay contacts being connected to rings.

Filed: 1968-10-01
Abstract: 1,193,602. Gas turbine vehicles. FORD MOTOR CO. Ltd. 1 Oct., 1968 [2 Oct., 1967], No. 46485/68. Heading B7H. [Also in Division F2] In a motor vehicle having front and rear axles 10, 12 and a gas turbine engine 26 of the free power turbine type, the rear axle 12 is driven from the power turbine 34 of the engine and the front axle 10 is selectively driven from the compressor shaft 30 of the engine through a variableslip clutch 50 which is controlled by fluid pressure derived from a fluid pressure source through pressure controlling means arranged to vary the clutch slip and hence the load on the compressor shaft. The power turbine 34 drives the rear wheels 16 through reduction gearing 40, transmission 42 and differential gearing 20. The compressor shaft 30 is connected to the front wheels 14 through a reduction gear train 46, the clutch 50, differential gearing 18 and universal joints 22 which permit steering of the wheels. The clutch 50 is a viscous friction type having a spring-released driven plate 52 splined to the differential input shaft 54 and urged into engagement with a driving-plate 48 by application of fluid pressure to an annular piston 56 in a chamber 60. A pump 64 driven by an electric motor or from the reduction train 46 is connected to the chamber 60 through a constantpressure regulator 68 and a three-position control valve 70 providing for complete disengagement of the clutch 50 to allow rapid acceleration of the compressor shaft 30, for full engagement of the clutch 50 to retard the vehicle by driving the compressor shaft, and for the clutch 50 to be controlled by a pressure modulator 74 which varies the clutch engagement in accordance with the compressor shaft speed as sensed through a connection 76. The pressure modulator 74 supplies the clutch 50 from a comparator valve 86 (Fig. 2) actuated by the pressure differential between a first pressure which is derived from a set temperature pressure regulator 82 and is varied in accordance with a predetermined schedule depending on the compressor shaft speed as sensed by a speed signal generator 80, and a second pressure which is varied in accordance with the actual turbine inlet temperature of the engine by a valve 142 actuated by a temperature sensitive probe 84. Should the actual temperature rise above or fall below the set temperature corresponding to the compressor speed, the pressure modulator 74 decreases or increases slip at the clutch 50 to speed up or slow down the compressor. An engine fuel governor will then correspondingly reduce or increase the fuel supply to restore the temperature to the set value.

Abstract: 1360455 Signalling over power lines BROWN BOVERI & CIE AG 8 Oct 1971 [10 Oct 1970] 46998/71 Heading H4R In an arrangement for remote control signalling over a multiphase power distribution system, in which the signals are introduced into the system at spaced points by working simultaneously transmitters synchronized and supplied with control pulses from a common point, each transmitter includes a pulse oscillator, normally synchronized by synchronization signals from the common point, and driving a counting ring which functions as a grid control set for a multiphase inverter, and monitoring circuitry in each transmitter responds to loss of synchronization signals to prevent resynchronization upon restoration of these signals until the end of the next control pulse, and is adapted to inhibit the synchronizing signals during periods in which distortion of those signals is detected. The Figure shows a single transmitter coupled to a common source 2 of synchronizing frequency and a common source 10 of information pulses. The synchronizing frequency is converted to square wave at 4 and normally passes through a gate 13 is differentiated at 7 and passes through a gate 14, synchronizing an oscillator 6 producing three pulses per differentiation pulse. For each information pulse from source 10 a bi-stable 11 is set allowing the pulses from oscillator 6 to cycle a ring counter 8 through its active states enabling the grids of valves in the multi-phase inverter 1 causing a multi-phase pulse to be transmitted to the power system. The trailing edge of the information pulse triggers a monostable 21 which resets the bi-stable 11 resetting counter 8 and closing gate 12. Each pulse from the squarer 4 are also delayed at 19 for part of the duration of a pulse and triggers a monostable 20 producing pulses of standard form which are inverted and applied to AND gate 14. The pulses of the inverted waveform normally enable gate 14 in time to pass the next differentiated pulse, but if distortion causes two successive positive pulses from 4 to be closely spaced in time the gate 14 does not open in time to pass the second differentiated pulse. The standard pulse output of monostable 20 is also applied without inversion to an integrator 16 adapted to set a bi-stable 17 if no pulses are received over a period. Setting of the bi-stable blocks an AND gate 13 blocking the synchronizing signal supply to the oscillator which continues without synchronization. Bi-stable 17 is only reset opening gate 13 at the end of an information pulse by monostable 21 via a delay 22. Thus when the synchronizing signals reappear synchronization can only occur between information pulses and all transmitters remain in phase.
