Title: Improvements in latches of the type which are used in conjunction with pin tumbler locks
IPC: E05C1/16
Filed: 1926-02-03
Abstract: 268,492. Tonks & Sons, Ltd., E., and Tonks, C. W. Feb. 3, 1926. Night latches and like spring locks.-The latch bolt of a lock of the pin-tumbler type is deadlocked by a pivoted or sliding bolt D having an abutment n on its forward edge to engage the latch and a notch m in its rear edge engaged by an arm on the follower boss. The latch is operated by the arm d which is loosely mounted on the follower boss, and the dead locking bolt D is operated by the arm k on a ring f locked to the boss. With the mechanism in the position shown in Fig. 1, the latch bolt is drawn back by 'turning the key in an anti-clockwise direction so that projection i on the ring f presses the arm d against the plate e, To dead-lock the latch bolt with the mechanism as shown in Fig. 1, the key is turned in a clock-wise direction. The arm d is not moved at first, but the arm k moves round to the notch m and moves the bolt D until the abutment n is behind the abutment of the latch bolt when its movement is stopped by the pin t; the parts are then in the positions shown in Fig. 3. The key must be rotated through 360‹ before it can be withdrawn, and the last part of the rotation of the key causes the projection j to engage the left-hand side of the arm d which is thus moved slightly. The first anticlockwise rotation of the key operates the dead-locking bolt D and the second withdraws the latch bolt.

Title: Improvements in or relating to telephone systems
IPC: H04J1/14
Filed: 1922-02-02
Abstract: 196,123. Western Electric Co., Ltd., (Western Electric Co., Inc.). Feb. 2, 1922. Addition to 170,286. Wired wireless systems; calling systems; multiplex signalling.-In a multiplex system wherein a signalling device associated with one end of a transmission line is operated in response to the withdrawal of normally-applied carrierwave oscillations at the other end of the line, as described in the parent Specification, means is also provided for preventing the operation of the signalling device in the event of failure or breakdown of all the carrier waves in the system. The Figure shows parts of a system in which each line L<1> is associated with the main transmission line ML through a transmitting channel TL<1> and a receiving channel RL'. Continuous oscillations from a high-frequency generator O<1> are supplied to the grid circuit of a modulating valve M<1> through a potentiometer 31 and, during speech transmission, are modulated by low-frequency voice currents from the line L', also applied to the grid-circuit through a transformer 30. A band filter TF<1> permits the passage of one side band of the modulated carrier waves through the transformer 15 to the line ML, the other side band being suppressed. The received modulated and unmcdulated carrier waves pass through a band filter RF<1> at the cooperating receiving station to a detector D<1> and the reproduced low-frequency currents after passing through an amplifier RA<1> and transformer 32 are selected by a filter RF1<1> and pass to the line L'. The unmodulated carrier waves also appear in the output circuit cf the detector D' and pass through a filter RE1<11> to a rectifier R' which converts them into direct current to energizes a relay 26. When transmitting a calling signal, the application of ringing current to the line L<1> energizes a relay 24 which breaks the connection from the battery J3 to the plate circuits of oscillator O<1> and modulator M<1>. The interruption of the carrier wave at the distant receiving station causes relay 26 to de-energize, extinguishing a lamp 34 and completing a circuit for a relay 27 which connects. a ringing-generator to the line L<1> to give a calling signal. The circuit of relay 27 includes two bus-bars 35, 36 which are connected together over the parallelconnected front contacts of relays 26 in all the receiving channels. As long as any of the stations are not calling, the circuit for relay 27 will be completed over the front contact of one of the other relays 26, but in the event of the complete failure or breakdown of all the carrier waves, all the relays 26 will de-energize, opening the circuits of all the relays 27 so as to prevent tbe transmission of a failse ringing signal. At the, same time, the extinguishing of all the lamps 34 attracts the attention of an attendant. blillia,mmeters 33, in series with the relays 26, indicate variations in the amplitude of the carrier currents. Keys 37, 38 are provided for testing purposes. '

Title: High-frequency pulse generator
IPC: H03K3/55
Filed: 1946-01-31
Abstract: 607,365. Pulse generating circuits. HAZELTINE CORPORATION. Jan. 31, 1946, No. 3169. Convention date, Feb. 27, 1945. [Class 40 (vi)] A pulse is generated by the charging of an energy-storage device, a further pulse of the same polarity being generated by the discharge of the device. When line 10 is in its discharged state, thyratron 16 is held non- conducting due to the bias on the control grid. A triggering pulse applied to cathode follower 43 is amplified in valve 46 and fed over transformer 21 to fire thyratron 16, the resulting anode current flowing through the primary of the pulse transformer 27 to charge the line 10, thereby developing a pulse in the secondary winding. The firing pulse is also fed over capacitor 47 to the grid of thyratron 25, but due to the low anode potential and the connection over resistor 30 the grid is held sufficiently negative to prevent it firing. When the charging of line 10 is completed the cathode potential of thyratron 16 rises, extinguishing the valve. The succeeding triggering pulse is effective in firing thyratron 25 since the rise in anode potential due to the charging of the line 10 has reduced the grid bias, the line discharging through the other primary of transformer 27 and the valve to generate a further pulse. The thyratron 16 is not fired due to the highnegative grid bias and low anode potential. In a modification, Fig. 3, (not shown), the line 10 is made symmetrical with respect to earth and the H.T. supply to ensure equal amplitude pulses for the charge and discharge of the line. Specification 3167/46, as open to inspection under Sect. 91, is referred to.
