Title: Improvements relating to automatic and semi-automatic telephone systems
IPC: H04Q3/00
Filed: 1925-08-27
Abstract: 261,128. Siemens Bros. & Co., Ltd., and Patterson, W. G. Aug. 27, 1925. Automatic exchange systems; metering.-In a system employing switches of the Strowger type and having feed current supplied from the connector, the incoming test wire of an idle switch is connected to battery over a shaft contact, and is grounded by the release relay upon seizure of the switch to hold the preceding switch or switches. The invention may also be applied to the repeater at the outgoing end of a two-wire trunk, and to the 'A' digit switch in a system employing register-controllers. Line switch, Fig. 1. When an idle link is reached, switching relay T is energized over winding 1 by battery over the test terminal, and looks over both windings to ground at contact r1, which is replaced by ground fed back over the test terminal before line relay R relapses. Group selector, Fig. 2, with continuous test wire. The rotary magnet RM operates under control of its contact rm until an idle link is reached, whereupon test and switching relay G is energized by battery over the test terminal, and locks over off-normal contact k1 to ground at contact bl, which is replaced by ground fed back over the test terminal, before release, relay B relapses. The incoming test wire is connected through to the test wiper at contact q1. If no idle link is found, the switch moves into the 11th position, and relay G energizes over contacts s2, connecting up the busy signal, and a statistical meter is operated over contacts s1. Connector, Fig. 3. Release relay B grounds the test wire at contact b3. Change-over relay G falls back slowly when all the impulses have been received, and connects up relay S, which supplies ringing current to the called line or busy tone to the calling line according as test relay, H is energized or not. Ring cut-off relay F upon energization applies booster metering battery to the test wire for an interval dependent on the release time of relay S. Group selector with discontinuous test wire. Fig. 2 is modified by providing a separate contact of relay B for operating relay G, and the incoming test wire is grounded over a front contact of relay G when the succeeding switch is seized. In this case metering is preferably effected by the reversal of line current at the connector.

Title: Improvements in interlocking machines for railways
IPC: B61L19/14
Filed: 1930-07-17
Abstract: 354,973. Railway signal interlocking frames. GENERAL RAILWAY SIGNAL CO., Rochester, New York, U.S.A.-(Assignees of Howe, W. K. ; 333, Oxford Street, Rochester, New York, U.S.A.) July 17, 1930, No. 21692. Convention date, July 23, 1929. [Class 105.] In an interlocking machine the control levers are slidably operated and provided with a lever latch to hold them in their extreme positions and the tappet bars are controlled by both the control lever and the lever latch. The lever latch cannot be moved when the control lever is in an intermediate position. The control lever L, Fig. 1, slides horizontally to actuate a circuit controller 30 and by means of a slot receiving a pin 45 on a pivoted lever 42 actuates other circuit controllers 39 ; an indication lock magnet 18 and a magnet 21 with associated contact 82 for lifting a locking dog which is mechanically forced into locking engagement at the end of the stroke are provided. A pushbutton 54 for actuating a switch 22 is controlled by the slidable control lever L. The vertically arranged tappet bars 87, Fig. 4, are moved by levers 76 which have a fixed pivot on an extension from the bed 16 on which the control levers L are slidably carried. The pivoted levers are actuated by a pin 80 engaging a slot 72a in the lever latch 72 which is tensioned by a spring 74. The pin 80 projects through a gate slot Lc in the control lever L so that the lever latch 72 must be gripped to lift the pin 80 into register with the horizontal part of the slot Lc before the control lever L can be slidably operated to the left ; at the completion of the movement and on release of the lever latch 72 the pin 80 is moved to the upper end of the vertical part of the gate slot. The tappet levers 87 are therefore moved to an intermediate position on gripping the lever latch 72, and after pulling out the control lever L and releasing the lever latch are moved to the final position. The contact 82 of the forcelock-removing magnet 21 is actuated by the lever latch 72 which engages a stud 86 to lift a bar 83 and stud 84. Figs. 3 and 3a show the locking of the pushbutton rod 55 by a cam 61 on the control lever L which in the normal position forces the lower of two offset lugs 62a, 62b which project inwardly from a ring member fixed to a rod 62 into a notch 55a on the push button rod which is therefore locked. When the control lever L is put to reverse, the push button can be operated and on doing so it is then locked by the upper projection 62a as the rod 62 is spring biased downwards. Return of the control lever releases the push button which is returned by a spring 56 and is again locked by the lower projection 62b when the control lever reaches its normal position.

Abstract: 1,243,160. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 8 May, 1970 [30 May, 1969], No. 22256/70. Heading G4A. A data processing system includes a CPU, ancillary (e.g. I/O) units connected thereto by a ring bus system comprising an address bus and a data bus, and switching means selectively operable in response to a signal indicative of the absence of execution of a programme instruction involving communication between the CPU and the ancillary units, to apply an address of an ancillary unit defined by manually settable test means to the address bus, the addressed unit supplying data via the data bus to the CPU. The switching means only operates in response to the signal in this way if a manual mode switch is set to "I/O display", the data sent to the CPU being sense data which is displayed on lamps on the CPU control panel. If the mode switch is set to "I/O status stop", then in the presence of the "signal" mentioned above, the machine stops (i.e. at the address defined by the manually settable test means) when the contents of the data bus equal the setting of further manual switches. When test and maintenance work as above is not being performed, the manually settable test means and the further manual switches are used as conventional address and data configuration switches, and the lamps are used for displaying register and storage contents.
