Title: Magnetic domain store

Filed: 1972-11-09
Abstract: 1395592 Magnetic storage arrangements PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 9 Nov 1972 [12 Nov 1971] 51757/72 Heading H3B Binary information is represented by the position of a cylindrical domain 4, Fig. 1, in a two-position bit location 5 in a sheet of magnetic material 1, the stored information being changed by first applying a light beam to locally heat the sheet above its compensation temperature, and then during the cooling phase applying an in-phase magnetic field h or h<SP>1</SP> in the direction in which domain movement is required. As shown a matrix of bit locations are provided in the sheet which has a normal bias field H stabilizing the domains. A domain is located in a selected position by a permalloy dot 2, 3, a permalloy strip 7, Fig. 2, or a pattern of permanent cylindrical domains 35 in an adjacent magnetic plate 34, Fig. 6. An in-plane field particular to each row of a matrix of bit locations may be produced by appropriately energizing the conductors 12, Fig. 3, of a set of parallel conductors, simultaneous domain movement in a selected column of bit locations being obtained in the cooling phase which follows optical heating of the selected column area 11. Generally the effect of heat is to alter a domain shape to that of a strip 4<SP>1</SP>, Figs. 1 and 2, which contracts to a cylindrical domain during the cooling phase in a direction determined by the direction of the in-phase field h, h<SP>1</SP>. An information storage system is shown in Fig. 4, in which a light beam 16 from a source 15 is directed on to a selected bit location 5 by a light deflection unit 19, the light source being controlled by a signal 18 so that high and low intensity beams, respectively, are provided for the thermal writing operation and for non- destructive optical read-out. An apertured plate 26 is located at the rear of sheet 1, with the apertures so positioned that light can pass through one position only of each of the twoposition bit locations 5 to a light guide 27 and a detector 28. An output 29 is produced by the detector when the plane of polarization of light transmitted through an interrogated location is rotated by the Faraday magnetooptic effect due to the presence of a domain in the apertured position. In a modification providing a word organized store, Fig. 8, the beam from the deflection unit passes through a beam splitter 41, the plurality of beams so produced being directed respectively to a corresponding location on each of a plurality of magnetic sheets 33 in structures 42. Each structure comprises a permanent cylindrical domain storage plate 34, an apertured plate 26 and a light guide 27 is addition to the magnetic sheet 33, the bit written into each sheet being determined by an associated field source 43 providing in-plane field h, h<SP>1</SP>. An arrangement is provided for maintaining the store at a constant temperature.

Title: Electronic computer systems
IPC: G06F12/04
Filed: 1973-11-09
Abstract: 1411167 Data processing systems INTERNATIONAL BUSINESS MACHINES CORP 9 Nov 1973 [4 Dec 1972] 52062/73 Heading G4A The system includes a backing store which feeds a buffer store via a register in the backing store. When the processor calls for a certain word a complete page of data is read from the backing store to the register. The register is then read out to the buffer such that the word called for is transferred first, followed by the remaining words of the page. The backing store may be in the form of a set of cards, one for each bit of a word, each carrying semiconductor chips which can each store a number of bits. The backing store in the described embodiment comprises 64 cards 13, Fig. 2A, each carrying 128 chips C1-C128. Each chip can store 128Î128 bits. A 14-bit word B8-B21 from the address register causes the bit in a particular location in each chip of each card to be read in to the associated registers L1-L128. A 7-bit word B1-B7 from the address register is decoded at 30 to set a ring counter 32 to enable a corresponding one of AND gates A1- A128. There is a decoder, a counter, and a set of AND gates on each card, and consequently the required 64-bit parallel bit word appears at the output of the store. Counters 32 are stepped by very high speed pulses so that the rest of the words of the selected page are read out in turn to the output during a single cycle of the store. The words read may include check bits for error correction or detection prior to transferring the page to the buffer store. The series of words may be passed to the buffer store via a bank of 128 AND gates (22, Fig. 1, not shown) formed on each card and enabled in turn by the output of a ring counter stepped at the same rate as counter 32, and set initially to a value dependent upon the address bits B1-B8. The buffer store feeds the processor via a register (26).

Patent GB-530136-A (GB)
Abstract: 530,136. Igniting gas burners. GROVES, W. W. (Junkers & Co. Ges.). June 17, 1939, No. 17737. [Class 75 (iii)] Gas is supplied to the mixing tube 14 of a burner head 1 by a cock 19 which when turned past its fully open position reduces the supply to the tube 14 but allows gas to pass through a bore 21 and nozzle 15 to a mixing tube 13 communicating with a catalytic ignition device 12 arranged in a chamber 2 inside the head 1. The ignited gas spreads through openings 8 below a burner cover 7 and ignites the gas issuing from openings 5 in the burner head. A spring 28 secured to the gas inlet connection 27 and engaged by a striker pin 29 on the cock returns the cock when released to the fully open position. Additional air to cause an explosive ignition flame is supplied to the chamber 2 through an opening 17 arranged below the ignition device 12, this opening also supplying air to cool the catalyst when the burner is alight. If the gas cock 19 is not returned to its correct position after ignition the flame lights back to the nozzle 15. The ignition device is mounted on a frame 11 in a removable cone 10 fitted with a handle 9.

Abstract: 1,165,157. Hydrostatic transmission. DOWTY HYDRAULIC UNITS Ltd. 24 Nov., 1966 [16 Dec., 1965], No. 53454/65. Headings F2C and F2D. In a hydrostatic transmission for a winding drum wherein a variable displacement pump 1 supplies a fixed displacement motor 4 and a by-pass valve 13 between the high and low pressure lines 2, 3 is normally opened by a servo 9 under the control of a relief valve 24 when the high pressure exceeds a predetermined value, the flow through a restriction 19 to an accumulator 34 during a rapid rise in high pressure causes a pressure differential across a piston 12 of the servo which opens the by-pass valve 13 at a pressure lower than the predetermined value. As shown a non-return valve 10 connects the high pressure line to a servo chamber 17 which communicates through the restriction 19 with a chamber 18 connected to both the relief valve 24 and accumulator 34. With equal pressures in the chambers 17, 18 acting on differential areas of the piston 12 the by-pass valve 13 is closed. The spring loading of the accumulator 34 is such that its piston 32 begins to move before the relief valve 24 opens. During a slow rise in high pressure the flow through the restriction 19 to the accumulator 34 creates insufficient pressure differential across the piston 12 to open the by-pass valve 13. Thus the pressure in both chambers 17, 18 rises until the relief valve 24 opens at a predetermined pressure to create a pressure differential across the piston 12 which opens the by-pass valve 13. During a rapid rise in high pressure the flow through the restriction 19 to the accumulator 34 creates sufficient pressure differential across the piston 12 to open the by-pass valve 13 before the relief valve 24 opens, and thus when the rapidly rising pressure opens the relief valve 24 the by-pass valve 13 is already open and the predetermined pressure is not exceeded due to a time lag in the valve 13 opening. The chamber 18 may be vented by a manually controlled valve (not shown) to neutralize the transmission. A spring may bias the piston 12 to a position in which the by-pass valve 13 is closed. A make-up pump 5 delivers through a shuttle valve 7 to the low pressure line. The piston 12 may be replaced by a differential area flexible diaphragm and the chamber 18 may be supplied through a restricttion directly from the line 8.
