Abstract: 826,697. Lift control systems. WESTING- HOUSE ELECTRIC CORPORATION. Jan. 31, 1957, No. 3380/57. Drawings to Specification. Class 78 (3). In a control apparatus for a lift system having one or more cars serving a plurality of landings, the system is transferred to any one of a plurality of modes of operation by means responsive to the ratio of stops made in one direction of travel to the total number of stops made. The modes of operation described meet the traffic demand during " off hour," " up peak," " off peak " and " down peak " periods. In a device for measuring the demand on the system (Fig. 4, not shown) the resistances of two arms of a bridge circuit are varied by rotary switches which are stepped respectively by each car stop and by each car stop in one direction, the arrangement being such that when a predetermined unbalance occurs, a relay is operated to change the mode of operation. The system described includes means for reversing the car if it is loaded and has no further car calls in its direction of travel; means for assigning one car only to answer up calls during down peak periods; means which, during peak periods, cancels landing calls for service in one direction when a car set for travel in the other direction stops at that landing, but which permits immediate re-registration of the call, even while the car is stopped at that landing; and means for varying the non-interference time in accordance with predetermined conditions.

Title: Improvements relating to pressure measuring apparatus
IPC: G01L9/00
Filed: 1942-03-23
Abstract: 553,821. Valves. INTERNATIONAL ALLOYS, Ltd., PRYTHERCH, W. E., and TOPHAM, V. F. March 23, 1942, No. 3800. [Class 135] [Also in Group XIX] Comprises a mercury or like gauge inserted for resetting instruments and a multi-way valve having one port permanently connected with the gauge and having distributed ports adapted to be permanently connected to different loci and to be opened necessarily to the first-mentioned port and means for automatically and periodically setting the gauge and synchronously operating the valve. Fig. 1 shows a valve for connecting any of a number of pipes 7b, 8b, 9b with a pipe 6b. A circular disc top part 4 having an annular passage 10 and radial passage 10a has a trued face turning on a similar face on a base 1. The base has ports similar to the port 8 with any of which the passage 10a can be brought to register while a port 6 always in register with the annular passage 10 communicates with the pipe 6b. The part 4 is carried on a shaft 5 driven by worm gear from a motor 16 the shaft having upon it several cams 17, 18, 19. A motor 29 drives through belt gear a cam disc 34 carrying a McLeod gauge 13, 14 which is in communication with the pipe 6b. A motor 42 drives a control cam shaft 41. Assume the mains current to be switched on, and the motor 42 started, the first cam 36 allows mercury switch 36a to close and current is supplied to motor 16 via switch 20 the movable contact of which at this time engages extra contact 23. The cam shaft 5 is rotated until pipe 7b communicates with pipe 6b and the gauge 13, 14 which is in the position shown. The cam 17 in this position A displaces the movable contact 23 and stops motor 16 lighting lamp 7c. Next the cam 39 allows switch 39a to close and energize field 31 and cause counter electrical rotation of motor 29 to bring gauge 13, 14 into the vertical positions. The movable contact of switch 33, owing to cam 34 interrupts field 31, stops motor 29 and lights lamp 35. The mercury rises in limb 13a of the gauge and influences Wheatstone bridge 15, the out of balance being indicated and recorded at the galvanometer 15a. Next cam 40 causes switch 40a to close and energize field 30 of motor 29 through contact switch 32 which is closed when the gauge is vertical. The gauge is again tilted and the cam disc 34 opens switch 32 to interrupt the field and stops the motor. The cams 37, 38 cause pipes 8b, 9b to be connected to the gauge in succession similarly to pipe 7b lamps 8c, 9c lighting at appropriate times.

Abstract: 904,122. Fluid-pressure servomotor-control systems. SULZER FRERES S.A. Feb. 6, 1959 [Feb. 17, 1958], No. 4319/59. Class 135. Pressure signals responsive to fluid flow are transmitted by a valve 3, a relay 100 and a change-over valve 5, when the latter is in the position A shown, to a spring-loaded servomotor piston 6 controlling a throttle valve 70 in the flow line. The valve 5 also feeds these signals to one side of a spring-loaded piston 250 of a comparator 25, the other side of which piston is subject to a signal from a manual device 80 transmitted via a relay 120 and the valve 5; inequality in these signals translates the piston 250 and hence a slide valve 26 to direct fluid to and cause movement of a piston 180 to increase the spring-loading of the relay 120 until the signal transmitted by the latter is equal to that from relay 100. With the valve 5 in the position B the loading imposed by the piston 180 is slowly removed in a time dependent upon the setting of a throttle 34 across the piston whereupon the servomotor 6 is responsive to the manual device 80. The relay 100 is also provided with a comparator 27, slide valve 30 and piston 31 whereby its loading spring 33 is adjusted when the throttle valve 70 is controlled by the manual device 80 should the signals on either side of the piston of the comparator 27 be unequal. The piston 31 is connected to the spring 33 by a self-locking slide 32 and any loading imposed upon the spring 33 by the comparator 27 is immediately available for controlling the servomotor 6 as also are the flow-responsive signals when the valve is returned to the position A. In a modification, the equalization of either signal is effected by one set of apparatus, the change-over of the connections of which is done upon operating the valve 5. The manual signal may be replaced by an automatic one from another system. The regulating apparatus may be used to maintain constant the internal temperature of a building irrespective of the ambient conditions. The apparatus may be applied to mechanical, electrical or electro-mechanical systems and signal equalization need only be effected when the valve 5 is operated. The response of the valve 3 may have a linear or quadratic relationship with the measured value of the signal.
