Title: Anti-locking braking system
IPC: B60T8/42
Filed: 1973-03-08
Abstract: 1417609 Anti-lock braking systems AUTOMOBILES CITROEN 8 March 1973 [9 March 1972] 11348/73 Heading F2F An anti-lock vehicle braking system includes a valve 1 with a slide 1a operable by a winding when locking of one or more wheels is sensed to disconnect one or more wheel cylinders 2 from a source of pressure and connect them with an exhaust conduit 14; the exhaust conduit 14 connects to a reservoir 29 via two routes and the route taken by the fluid exhausted from wheel cylinder(s) 2 depends on the pressure prevailing in the cylinder(s) 2 at the time wheellock was detected. This pressure acts on the piston 6a of an accumulator 6 against the bias of a calibrated spring 4 and when the pressure overcomes spring 4 the piston 6a is moved to bring about alteration of the route. Thus should lock occur at a low pressure indicative of bad road conditions the cylinder(s) 2 will be exhausted directly to reservoir 29 via a conduit 5, should lock occur above the threshold pressure overcoming spring 4 indicating good road conditions the cylinder(s) 2 will be exhusted via an accumulator 8 and via a flow limiter 7. In the embodiment of Fig. 1 the pressure source connects with valve 1 via a conduit 12 incorporating a filter 20 and the valve 1 connects with the cylinder 2 via a conduit 13 which is connected to the accumulator 6. The exhaust conduit 14 is connected via conduit 5 to the accumulator 6 and the piston 6a has a groove 30 which will allow flow past the accumulator 6 into reservoir 29 when the pressure in conduit 13 is insufficient to more piston 6a. Further conduits 21, 22 are also connected to the valve 1-these conduits 21, 22 are disconnected when the valve 1 is actuated but upon reconnection allow unthrottled flow from exhaust conduit 14 and accumulator 8 to the reservoir 29 via conduit 21, valve 1 and conduit 22. In the embodiment of Fig. 2, the accumulator 8 comprises two chambers 8c, 8d within the accumulator piston 6a and interconnected by a flow limiting aperture 7 in a piston 8b. The piston 6a includes channels 31, 30, channel 31 permanently connecting chamber 8d with a groove 32 in the body of the accumulator 6. When lock is sensed at low brake pressure, conduit 13 is exhausted via conduit 14, channels 31, 30 and conduit 5. When lock is sensed at high brake pressure, conduit 13 is exhausted via accumulator 8 since piston 6 is now in a position where channel 31 is cut off from conduit 5.

Title: Means for improving the current carrying capacity of existing three phase alternating current cable systems
IPC: H02J3/04
Filed: 1919-09-23
Abstract: 164,689. Taylor, A. M. Sept. 23, 1919. Systems depending on the use of static transformers and of two or more machines.- Three feeders of a three-phase electric supply system are employed to transmit an additional three-phase current, the frequency of which is the same as that of the normal supply. The voltage of the additional current may be greater than that of the normal supply, and the current is led to feeders through the neutral points of transformers or static balancers. In a modification, the additional current is fed over two feeders or through a six-core cable constituting two feeders. Three feeders 3PC, Fig. 1, are connected to the main generators MG through step-up transformers SUT, the neutral points of the. star-connected secondaries of which are connected to an auxiliary generator AG, of the same frequency as the main generators MG, through a transformer ASUT. Current from the main generators is supplied to the bus-bars BB through transformers P<2>S<2> and from the auxiliary generator through transformers P<1>S<1>. In a. modification, the auxiliary generator AG is not connected to the bus-bars of the main generators in order that its voltage may be raised above that of the main generators. In a further modification, the auxiliary generator is connected to the feeders through an auto-transformer. In the modification shown in Fig. 2, the secondary winding of the transformers at the generating end are arranged in V-connection, and the additional three-phase current is supplied over two feeders or one six-core cable. Specifications 158,008 and 179,824 are referred to.

Title: Improvements in or relating to telecommunication exchange systems
Inventor: WRIGHT ESMOND PHILIP GOODWIN
IPC: H04Q3/00
Filed: 1948-04-26
Abstract: 654,884. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. April 26, 1948, No. 11428. [Class 40 (iv)] In a long-distance telecommunication system a forward transfer signal is normally repeated forward by a tandem exchange unless congested conditions have been encountered, in which case the signal is diverted to local equipment at the tandem exchange which may revert a busy signal or a delay duration signal, whereupon a second forward transfer signal diverts the call to an operator. Arrangements are described at the originating exchange, Fig. 2 (not 'shown), whereby both demand and delay operators have access to inter-exchange lines, but the former is prevented from sending the forward transfer signal. In the tandem exchange, Fig. 3, the circuits for switching the speech circuits are omitted. Incoming digits received by the V.F. receiver 3002 set the switch (having wipers 3003 ... 3008), after which 3009 comes up. If there is a free line in the wanted direction earth over wiper 3005 brings up relay 3010 which operates the start relay 3014 for hunting switch 3025 associated with the outgoing line. When the switch reaches the position marked over wiper 3004 the test relay in the finder operates to stop the switch and 3013 comes up, opens the circuit of its low resistance winding to busy the circuit, and releases start relay 3014. Switch-through and conditioning of the V.F. equipment to allow through all subsequent signals (except release) takes place in the usual manner. If all outlets in the wanted direction are busy, relay 3011 no  longer short-circuited over wiper 3005 comes up in series with 3010, and reverts a busy signal. If a forward transfer signal is now received 3002 brings up 3015 to operate the start relay 3016 of a finder, associated with delay signalling equipment, and when the circuit is found 3013 operates in series with the finder stop relay over wiper 3007 and releases the start relay 3016. The delay equipment then makes a suitable announcement to the originating operator. If a further forward transfer signal is now received 3017 operates to call up over wiper 3006 a finder associated with an operator's position. Specifications 645,303 and 654,883 are referred to.
