Title: Magnetic bubble domain memory
IPC: G11C11/14
Filed: 1973-05-21
Abstract: 1426894 Magnetic storage arrangements INTERNATIONAL BUSINESS MACHINES CORP 21 May 1973 [22 June 1972] 24037/73 Heading H3B Information in the form of bubble domains in closed loop storage paths SL1-SL3, Fig. 3, is registered in a magnetic storage sheet 12S removably positioned adjacent a magnetic transfer sheet 12T used for writing and reading information into and from the storage sheet, the transfer sheet including magnetically soft overlay patterns for propagating bubble domains in both the storage and the transfer sheets and being directly associated with circuitry controlling such functions as decoding, writing, reading and clearing. Domains are propagated by an in-plane rotating magnetic field H and are size-determined by a bias field Hz. Domains propagated in an overlay pattern S2 on the transfer sheet will effect corresponding movement of domains in the underlying storage path SL1-SL3 of the storage sheet. If a current loop L1-L3 is energized circulated domains will be diverted from a circulating path in the storage sheet to a selected path B1-B3. In this path a storage domain interacts with a bubble generator 56 to produce a bubble which propagates along path 58 to a read out position. Bubble generation is effected by a permanent bubble 64, Fig. 4A, rotating about a magnetically soft element 66, the bubble 64 being split and moving along a path 72 if a storage sheet bubble 61 is moved along a path B1-B3 to the underlying position shown. Similar bubble generators provided on the storage sheet. for writing are used in Fig. 6, a permanent bubble rotating about a generator G1-G3 being split and passing into a path SL1-SL3 when a conductor loop L1-L3 on the transfer loop is selectively pulsed. An alternative form of writing bubble generator is shown in Fig. 5A, in which a domain 78 is nucleated at the end of a magnetically soft element 76A-76C, when a conductor loop L1-L3 on the transfer sheet is selectively pulsed at the same time as the bias field is temporarily reduced. A further writing arrangement is shown in Fig. 5B in which a domain 78 is introduced in the storage sheet only when two domains generated at G1, G2 in the transfer sheet and annihilated at Al, A2 arrive together at the domain 78 position. Reading may alternatively be effected by coupling of a storage sheet domain with a storage sheet conductor. For positioning a storage sheet correctly with respect to a transfer sheet the servo control shown in Fig. 2 may be used, domains in the storage sheet 125 being used for alignment. A laser 46 providing localized heating may assist domain nucleation. The arrangement may be used in a mechanical storage sheet filing system.

Abstract: 1429645 Gas turbine plant PROGRESS JETS Ltd 17 July 1973 [23 May 1972] 24088/72 Heading F1G [Also in Division F4] The invention relates to a method of producing a heated air screen which can be directed across the entrance opening 12 of a building, the air screen being formed by the exhaust gases of a gas turbine engine 10. It is arranged that the velocity of the exhaust gases is proportional to the rate at which fuel is supplied to the engine, there being means in the form of an anemometer for measuring the velocity of the air outside the entrance opening in a direction normal thereto, also means for controlling the rate of fuel supply to the turbine, such as a fuel pump 14. The fuel pump, or other fuel controlling means, is operatively connected to the anemometer so that an increase in the velocity of air normal to the entrance will result in an increase in the rate of fuel supply to the engine, and vice versa. The temperature of the hot exhaust gases may be reduced to say, 50‹C, by mixing air from a fan with the hot gases being discharged from the duct 11.
