Title: Circuit arrangement for telephone exchanges to enable an existing call to be temporarily interrupted
IPC: G09B5/00
Filed: 1969-05-14
Abstract: 1,235,966. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 14 May, 1969 [21 May, 1968], No. 24547/69. Heading H4K. A junctor used for a connection between one party and say a dictating machine, a teaching machine or another party of a P.B.X. has an auxiliary inlet to which a further party wishing to break into the connection can be connected and switching means arranged to switchover the said one party to the auxiliary inlet and to reinstate the original connection under control of that party when the interim conversation is complete. The systems described employ reed relay cross-point switch matrices. If the exchange is a P.B.X. each internal junctor has an auxiliary inlet and a timer such as a thermo relay which allows switchover to take place if the existing call exceeds a predetermined duration. Some subscribers may not have facilities to interrupt existing calls. In other exchanges described interrupt can only take place for calls between subscribers and supplementary equipment such as dictating machines. In these exchanges the modified junctors do not include a timer and are located on the subscribers side of the switching network. One such junctor shown in the drawing at DVS connects between the switching network KN and a dictating machine DG and has an auxiliary inlet E. During a connection between T 1  and DG via line circuit TS1, the switching network, an internal junctor IVS1, the switching network and junctor DVS, a call from T2 is connected via TS2, the switching network, an internal junctor IVS2, and the switching network to inlet E which if a call waiting signal has been given and the subscriber T 1  has consented operates relay UM effecting switching within that junctor of the changeover contact um. Prior to this connection the identifier discovers via the dotted-line conductors 3 to 6 the identity of the subscriber or equipment to which the line T 1  is connected and the translator operates a relay contact u signalling to the control unit St if connection is to a supplementary equipment. In another embodiment when a subscriber connects to a supplementary equipment this fact is recorded in his class of service translator after that equipment has been identified and during an intercept call identification only takes place if the translator indicates that the called party is connected to a supplementary equipment.

Title: Improvements in automatic control for motor vehicles
IPC: B60K23/02
Filed: 1932-09-07
Abstract: 407,031. Controlling motor vehicles. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. Sept. 7, 1932, No. 24909. Convention date, Sept. 7, 1931. [Class 79 (v).] The clutch is engaged on application of the brakes, but is disengaged before the vehicle comes to rest. As shown, the clutch-pedal 18 is operated by a vacuum cylinder 14 adapted to be connected to the engine induction 12, or to atmosphere, by valve mechanism 22 and further controlled by a cock 38 operated from the brake-pedal 44 through links 42, 40. When the vehicle is running, the parts are in the position shown in Fig. 1, a relatively low vacuum being applied to the opening 26, Fig. 2, and the cock 38 being closed. When the engine throttle is closed, the vacuum in the induction pipe increases, and the valve 32 is opened, thus allowing the valve 35, which is rigidly connected to it, to close. The cylinder 14 is thus exhausted through the pipe 28, and the clutch disengaged. If the brake is now applied, the cock 38 is opened and air, rushing in through the valve 46, suppresses the vacuum near the valve 32, which then closes and allows the valve 35 to open, venting the cylinder 14 so that the clutch is re-engaged. As the vehicle slows down, air is sucked past the valve 46 at a decreasing rate until finally the valve closes. A vacuum again begins to build up behind the valves 46, 32, but since the valve 32 is loaded to open at a lower degree of vacuum, it opens first, thus allowing the vacuum to be applied to the cylinder 14 so as to redisengage the clutch and prevent " choking " of the engine when the vehicle comes to rest. The Specification as open to inspection under Sect. 91 also describes valve mechanism in which the valve 35 is omitted, but which is stated to operate similarly to the arrangement described above ; and a mechanism in which valves 35, 46 are both omitted, the vehicle being permitted to come to rest with the clutch engaged. This subject-matter does not appear in the Specification as accepted.
