Patent GB-643193-A (GB)
Abstract: 643,193. Operating clutches. NATIONAL CASH REGISTER CO. March 10, 1948, No. 7349. Convention date Aug. 29, 1947. [Class 80(ii)] [Also in Group XIX] A calculating machine includes a driven member, a motor adapted to be energized to drive the member through a cycle of revolution, means to disconnect the energizing force from the motor prior to the completion of the cycle and means operated by the momentum of the motor, after it has been de-energized, positively to effect the completion of the cycle by the member. Depression of a starting key 26, Fig. 1, permits a three-armed lever 24, 28 to rock under the action of a spring 27 so as to close a switch 33 for an electric motor and to remove an arm 21, secured to the lever, from engagement with a shoulder of a spring pawl 20 pivoted on a disc secured to a gear 17. The pawl thus clutches the gear 17, which meshes with a gear 18 on the main shaft 19, to a toothed member 14 fast to a gear 13 meshing with a gear 12 on the motor shaft 10. Near the end of the cycle, a stud 36 on the gear 18 engages a cam surface 37 of the lever-arm 24 and restores this lever, thus opening the motor-switch and withdrawing the pawl 20 which engages a positive stop 40. In order to ensure completion of the cycle, a shoulder 49, Fig. 2, of a cam 47 on the main-shaft is then engaged by a slide 42 which is urged upwardly into this engaging position by a spring 44 and oscillated to and fro by an eccentric 41 on the motor-shaft 10, which continues to rotate after the motor has been switched off due to the momentum of the armature. Specification 614,347, [Group XIX], is referred to.

Title: Sonar Detection System
IPC: G01S3/808
Filed: 1979-02-21
Abstract: The invention seeks to provide a sonar detection system relying on long term signal integration and which in one arrangement can be made insensitive to yawing of the vehicle which the system is fitted. A preferred embodiment of the invention employs a pair of hydrophone arrays (5, 9) located on a ship's keel, phased to produce pairs of beams. The signals from a selected pair (8, 11) are converted into a pulse train of fixed amplitude but varying duration and sampled (15, 24) prior to cross-correlation. A compensating delay is inserted in one signal path such that signals from a target symmetrically in the beams (8, 11) would be brought into time coincidence at the inputs (26, 27) to the correlator (20, 25). The delay means (63, 64, 67) responds to input from the ship's compass (78, 71, 70) to compensate for yaw. Tracking may be continuous in one sense through 360 DEG . The integrator 35 enhances the signal-to-noise ratio. The delay matrix (64) may be made responsive to the variation of acoustic velocity in sea water with temperature. <IMAGE>

Title: Position control apparatus
IPC: G05B19/39
Filed: 1979-03-29
Abstract: A photoelectric transducer (14) produces first and second periodic signals (A), (B) which are 90 DEG  out of phase with each other in response to rotation of a servo motor shaft (12a). The signals (A), (B) are differentiated, rectified and summed to produce a velocity signal (Vw+), (Vw-) having a magnitude proportional to the rotational velocity of the shaft (12a). The peaks of signals (A), (B) are detected in reference generator (28) to produce a reference signal the magnitude of which is reduced in accordance with the difference between the present and command positions of the shaft (12a) to produce a velocity c command signal (Vc+), (Vc-). The velocity signal (Vw+), (Vw-) is compared with the velocity command signal (Vc+), (Vc-) to produce a drive signal which is applied to the motor (12). When the shaft is near the command position, position counter (33) de-energises amplifiers (24) and (26) and the signals A and dA/dt are summed in amplifier (35) to provide a stop signal. <IMAGE>

Title: Electrooptical time indicating means
IPC: G04G9/02
Filed: 1979-07-10
Abstract: An electro-optical time-indicating system displays the time by simulating a clock using dial hands. The electrodes of a liquid crystal display are formed by radial track segments and the backing electrodes are subdivided into inner and outer electrodes. The driving of the track segments to indicate hours, minutes and seconds is accomplished by a time division multiplex technique. In order to keep the number of electrode terminals for the track segments to a minimum, the track segments are combined into L track segment cascades with L input terminals. The track segments are arranged in K twin sets such that, as viewed in the clockwise direction, an nth track segment (where n ranges from 1 to L) of one set of the twin sets is always connected with the L+1-nth track segment of the other set of a twin set. The inner backing electrodes are subdivided into M inner blocks with one terminal each, and the outer backing electrodes are divided into N outer blocks with one terminal each. Each twin set is covered by two adjacent inner blocks and two adjacent outer blocks. The time-functional drive of the terminals of the track segment cascades takes place alternatingly in ascending and in descending order, and successive terminals of the inner and outer blocks are energized in a clockwise direction after every change-over between ascending and descending drive.
