Title: Improvements in or relating to fluid pressure control valves
IPC: B60T15/42
Filed: 1965-05-04
Abstract: 1,082,088. Valves. AUTOBRZDY JABLONEC NARODNI PODNIK. May 4, 1965 [May 6, 1964], No. 18707/65. Heading F2V. When actuating fluid is admitted to a control port 26 it depresses a moving closure 6 on to a seat 14 on the end of a tubular plunger 15 so cutting - off communication between an outlet port 10, e.g. connected to brake cylinder, and an atmospheric port 13. Continued movement of the closure 6 causes the plunger 15 to slide and unseat a second closure member 3 so opening a supply port 4 to the outlet port 10; the fluid supplies to the brake also traverses the tube 15 and tends to unseat the closure 6 as well as acting on the piston part of the tube 15 tending to lift it. When the force due to the brake fluid pressure exceeds that due to the actuating fluid the tube 15 is elevated and both closures assume the lapped position; the brake fluid pressure seeks to unseat the closure 6 which it does when the actuating fluid pressure falls, due e.g. to releasing the brake pedal, whereupon the brake pressure exhausts through port 13. The closure 6 may be operated mechanically instead of by fluid pressure.

Abstract: 1,174,061. Tilting tray hydrographic model. B. G. WHITE, W. E. GELSON, A.H. BECKETT, and J. W. T. TAPP. 13 March, 1967 [29 April, 1966], No. 18957/66. Heading G5G. A tilting tray hydrographic model for setting up a working model of a river bed or an estuary with its natural silting comprises a motor 64, mounted on a slide 50, which via a variable reduction gear 68, cam 74 and pivoted lever 84 effects rocking of a tray 2 about pivots 18. The tray includes a relief model of the river bed or estuary with water and loose bed material simulating silt therein. The amplitude of rocking movement is varied by turning a crank 54 thus effecting movement of the slide 50. The reduction gear also drives a cylinder 32 which carries a chart 43 having thereon a graph of the tidal movement at a particular location in the estuary. The simulated tidal movement at that location is sensed by a float 96 carried by a pivoted arm which has at its other end an obturator disc 100 which throws an image 104 on to the chart. The motor is controlled by a variable speed switch 92. The working model is set up when by appropriate adjustment of the switch 92, gear 68 and slide 50 the path of the image corresponds substantially to the graph. Electronic means may replace the manual controls, so that the speed and/or amplitude of tilt of the tray may be automatically adjusted when the light beam is not in correspondence with the graph on the chart.

Abstract: 1,271,098. Digital computers. KOMBINAT ZENTRONIK VEB. 15 April, 1969, No. 19281/69. Heading G4A. A word orientated electronic data processing machine is disclosed, in which digital data words are arranged in sentences, the address of each sentence being the address of the first word in the sentence and all sentence addresses forming an uniterrupted numerical sequence, the words of a number of sentences being arranged in groups such that each word in each sentence belongs to a different word group, the words of each group having a common address feature, the length of each sentence of said number of sentences being the same, and said length being variable by a read only program device forming part of the machine. A drum or disc store SP can have a capacity of 600 or 1200 words, each word comprising 48 bits and representing binary coded decimal numerical information (11 digits + sign) or alphanumeric information (8 characters). The sentences are programmed for variable length to utilize the store efficiently and, for accounting applications, a total word in the sentence is called up by the sentence address. The address is entered through a typing unit SW or through a decimal keyboard ST into a decimal address counter AZ where the digits are coded in succession. The length of the sentence is determined by a plug-in programme device PE, and when the predetermined sentence length is reached an automatic stop is effected while for shorter sentences a separate stop instruction is provided. Store clearing is effected by the unit LSt using zero-balancing. For alphanumeric information in a 600 word store, 48 character sentences (i.e. 6 words per sentence) require 100 addresses. If 067 is the sentence address and the address of the first word then the other words have addresses 167 to 567. If however 200 addresses are needed (i.e. 3 word sentences), the word addresses are stepped to 067, 267, 467 since address 167 is now reserved for another word. Similarly for other different sentence lengths. For a 1200 word store the sentences are distributed over both 600 word halves.
