Abstract: 913,287. Selective punching-machines. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 31, 1959 [Dec. 31, 1958], No. 44442/59. Class 31 (2). [Also in Groups XXXVIII and XXXIX] In an electric circuit comprising an inductive element, a magnetic, two-state, storage device is connected across the element so as to be settable, through a substantially unidirectional conductive path, into a predetermined remanent state by the voltage pulse induced across the element upon de-energization thereof. As described, electromagnets M1 . . . M5 controlling the operation of card punches are selected by switches S1 . . . S5. When a switch is opened, the inductive effect momentarily causes a reverse voltage at terminals 15, 16 of the electromagnet, and this is used to set an associated storage core C1 . . . C5. At a subsequent stage, the states of the cores are read out through windings 18 in response to a resetting pulse from a source 24. The arrangement also serves to suppress sparking at the switch contacts. Specification 684,273 is referred to.

Abstract: 1401940 Measuring vehicle loads KNORRBREMSE GmbH 27 Sept 1973 [27 Sept 1972] 45390/73 Heading G1W [Also in Division F2] A spring plate 7 is acted upon by mechanical loading and applies a proportion thereof to a member, displaceable within a housing 1, which controls a pressure regulating valve, the plate having openings or portions of reduced thickness for resilient flexibility. The housing 1 is fixed to a rail vehicle frame and a thrust plate 18 bears on an axle bearing or part of the suspension which bears on the bearing. The mechanical loading on the suspension is transmitted from the thrust plate 18 via a ring 17, spaced inwardly from the periphery of the spring plate 7, to the plate 7. The loading is then transmitted to the housing 1 via a peripherally located ring 15 and to a diaphagm 2 via a ball 6 and a plate 5, the diaphragm abutting a spring biased plate 23 extending from a valve seat 24. The plate 7 has radial aperture 10, with the ball 6 engaging a bevelled central aperture, or an annular portion of reduced thickness; these features reduce the effect of tolerances on the resilient response of the plate. Increased loading produces upward diaphragm movement causing a spring-biased insert 32 with a dual-valve member 25 to rise from a seat 28 to allow air inflow from a pressure source via parts 30, 31 to a control chamber 3 to provide a balancing force on the diaphragm from this chamber the air flows to the brakes of the vehicle. Upon loading decrease, the diaphragm 2 drops so that the valve seat 24 moves away from the member 25 to allow fluid exhaust via a cap 34 until a balance is again attained, to lower brake pressure. The plate 7 can have many regions of reduced thickness and it may abut by its edge against the plate 5, here the ring 17 has a diameter far less than that of the plate 5.
