Title: Improvements in or relating to pulse multiplexing systems
IPC: H04J1/00
Filed: 1962-12-13
Abstract: 1,023,699. Pulse multiplex signalling. WESTERN ELECTRIC CO. Inc. Dec. 13, 1962 [Dec. 20, 1961], No. 47069/62. Headings H4L and H4R. In an asynchronous pulse - multiplexing-system, the outputs of a plurality of independent pulse transmitters are fed through respective filters having different (and separate) passbands. The filter outputs are then transmitted by, e.g. frequency modulation. At the receiver the demodulated signal is fed to corresponding filters from the outputs of which the original pulse signals are regenerated. In Figure 4, A, B, C are independent pulse transmitters whose outputs are applied to low pass filter 12 and band pass filters 23, 24 respectively. The filtered outputs, which are separated in frequency domain, frequency modulate the carrier wave of transmitter 10. The signals received at 11, are, after demodulation, applied to filters 14, 15, 25 corresponding in frequency range to filters 12, 23, 24 respectively. The output of low pass filter 14 is fed to pulse regenerator 16 which reproduces the pulse train from transmitter A. In order to obtain the original pulse trains from transmitters B, C the outputs from band pass filters 15, 25 are applied over envelope detectors 18 and low pass filters 19 to pulse regenerators 20.

Title: Elevator control system
IPC: B66B1/18
Filed: 1971-10-18
Abstract: 1358903 Multi - car control system HITACHI Ltd 18 Oct 1971 [19 Oct 1970] 48390/71 Heading B8L In a multi-car control system such that, at each floor, a passenger uses, one of an array of hall call buttons to indicate the desired destination floor, the call is allocated to that car for which a signal; proportional to the degree of coincidence between the source floor, desired destination floor(s) and the calls already assigned that car minus a signal representative of the work load of that car in reaching the source floor; is the greatest. Operation.-Upon operation of a hall call button HB, Fig. 4 (not shown) at a specific floor, the hall call register HCR comprising the apparatus of Fig. 4 for each floor, a flip-flop (FF), Fig. 5 (not shown), in the control CD, and corresponding to the specific floor is set after a delay of some seconds caused by delay (D1, Fig. 4) during which further calls from the specific floor can be registered. Operation of the flip-flop causes closure of a corresponding switch (SW), Fig. 6 (not shown), in the gate G1 allowing the hall calls, and the number of the specific floor to pass to the memory LAT under control of signal LSI. Signal IS renders the hall call register HCR insensitive to further calls until car selection has been made. Memories RUN A-RUN D store, for each car A-D the floors to be served, and coincidence detector A comprising, for each, car parts AA-AD, having AND gates (1-11), Fig. 7 (not shown) one for each floor and potential dividers (R, R 0 ), one for each car gives as outputs, signals to adders ANA-AND proportional to the number of coincidences between the contents of memory LAT and respective ones of RUN A-RUN D. Distance detectors SDA-SDD determine, for each car, a signal representing the number of calls allocated to the car before it would reach the specific floor, and the distance to be travelled, and, in adders ANA-AND, such signals are subtracted from the corresponding outputs of detectors AA-AD, the resulting signals to selector MMD causing the selection of the car belonging to the largest MMD input signal to answer the hall call(s) from the specific floor. Such selection, via signal LD, causes gates G2A-G2D to selectively open, causing the contents of the register HCR for the specific floor to pass into the memory RUN of the selected car. When the car calls at the specific floor, the contents of RUN appertaining to that floor is cancelled, any call information stored in the register for the specific floor in the car's motion direction since the car was selected is transferred to its RUN store, and the buttons (HB, Fig. 4), which remain depressed when used are reset. The memory RUN of an upward moving car does not store information requiring descent of that car, and vice-versa. Reference has been directed by the Comptroller to Specification 1,059,283.

Abstract: 1485844 Time switches; electromagnetic switches IZUMI DENKI CO Ltd 13 Nov 1974 [14 Nov 1973 (3)] 49130/74 Heading H1N A motor-driven timer comprises the combination of three pre-assembled units, a timing gear mechanism A, an electromagnetic actuator device, B, disposed on one side of the unit A, a contact assembly C disposed on one side of unit B and on said one or another side of unit A, whereby unit A effects the timing operation for the opening and closing of contacts in unit C in response to energization of device B. As shown unit A consists of support plates 3 and 4 spaced by members 1 and 2 and containing a reduction gear 5, a clutch 6, and a timing gear 7. The shaft of gear 7 carries a pointer 9 above plate 3 and a drive motor 8 is mounted on plate 4. The solenoid 13 with armature 15 is mounted to unit A by means of yoke 12, and three contact spring sets with associated bellcrank operating members 19 and 20 are secured in a frame 17 and mounted to yoke 12 by screws (24, Figs. 2 and 5, not shown). Members 19 and 20 have arms 19b, 20b and 20c co-operating with respective contact sets, and arms 19a and 20a acted on by tension springs 21 and 22. A spring leaf 15a extending from armature 15 normally urges arms 19a and 20a upwardly as shown since armature spring 16 is effectively stronger than springs 21, 22. Arm 19a also lifts shaft 61b to disengage clutch 6. When electromagnet 13 is energized spring 21 is permitted to turn member 19, thus engaging clutch 6 and operating associated change-over contacts to give a starting time signal. Motor 8 is energized simultaneously with the excitation of electromagnet 13. Gear 62 is thus driven and in turn rotates gear 7. After a predetermined time interval a projection 7a on gear 7 tilts a pivoted latch 10 to move clear of an arm 20d, allowing spring 22 to turn member 20, and arm 20b operates associated change-over contacts for the timing signal while arm 20c cams open other contacts to stop the motor 8. The direction of operation of the contacts being substantially perpendicular to that of the armature 15 prevents any shock from armature actuation adversely affecting contact operation.
