Title: Information store
IPC: G11B5/012
Filed: 1965-07-19
Abstract: 1,086,757. Electric digital data-storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 19, 1965 [July 27, 1964], No. 30503/65. Heading G4C. The addresses of a plurality of portions of a closed record track of a dynamic store required to be read out are specified simultaneously and read-out performed whenever the address of the portion currently in read-out position agrees with any one of them. In one embodiment, variable-length records are stored on each of three tracks of a magnetic disc store continuously driven. A recirculating shift register stores the addresses of the records in their order of occurrence on the disc store and is shifted by marks read from a fourth track of the disc. Such a mark is provided at the same angular position on the disc as the beginning of each record. The contents of the shift register stage corresponding to the next record to approach the three record reading heads (one per track) are compared continually with all the required addresses simultaneously, the required addresses having been stored in a further store (e.g. push-down) from a computer or keyboard. On an equality being obtained, the required address is gated to a head selector to read out the appropriate track, and erased from the further store. During read-out, further comparison is inhibited (until an end-ofrecord mark is read). The shift register may be replaced by a tape loop or counter. A second embodiment has a disc divided into sectors. The reading of a sector counter is compared with the sectors of required addresses which are specified by sector and track and stored in an associative memory. On equality, the track number(s) in the first or all matched addresses in the current sector is/are destructively read out to select track(s) on the disc store. In a modification the track numbers of required addresses are stored in sections of a core store determined by the sector numbers of the addresses and a commutator synchronized with the disc reads out destructively any track numbers stored in each section in turn to a head selector on the disc. The track numbers in a given section are read out together or one per revolution of the disc. Reference has been directed by the Comptroller to Specification 806,782.

Title: Improvements relating to vehicle suspension apparatus
IPC: B60G17/08
Filed: 1959-09-09
Abstract: 857,019. Adjusting body height. WESTING- HOUSE BREMSEN-G.m.b.H. Sept. 9, 1959 [Sept. 10, 1958], No. 30746/59. Class 108(2). A compressed fluid vehicle suspension comprises a regulating device for an air spring 3 and a damping device. The regulating device consists of two valves 5, 6, actuated by a piston 7. When load on the vehicle chassis 1 is increased, a disc 21 on a shaft 20 is turned in a clockwise direction causing the piston 7 to move from left to right opening the valve 5. Thus compressed fluid flows from a chamber 14 into a pipe 16 leading to the spring 3, until the vehicle has been raised to its normal height. The disc 21 also causes a double headed piston 25 to move from right to left causing an increase of pressure in a chamber 26a of damping fluid and a corresponding decrease of pressure in a chamber 26b. The two chambers are connected by a pipe 27 the restricted cross-section of which can be varied. When the load on the vehicle is decreased the reverse process takes place. Rapid dynamic load variations are absorbed by a flexible member 33. The two chambers 26a, 26b, are also connected through a pilot valve 36 comprising a spring loaded control piston 39 adapted to be operated pneumatically or hydraulically through a pipe 37. The valve 36 is normally closed but it can be actuated on application of the steering wheel, brakes or manually, to allow immediate pressure equalisation of the two chambers 26a, 26b, a rapid reaction of the piston 7, and of the air spring 3.
