Title: Data processing systems
IPC: G06F11/14
Filed: 1976-07-07
Abstract: 1505603 Data processing systems INTERNATIONAL BUSINESS MACHINES CORP 7 July 1976 28257/76 Heading G4A When a data item is to be changed as a result of an operation thereon by the central processing unit of a data processing system (not shown), a copy of the data item is transferred from the main store of the central processing unit to a non-volatile store (not shown) via a buffer store 24, and control means such as a counter 26 and a clock generator 28 initiate a read-out of data items from the buffer store 24 to the non-volatile store whenever either a predetermined number N of data items has been stored in the buffer store 24 or a predetermined time has elapsed from the storing of the first data item in the buffer store 24, the predetermined number or predetermined time being increased/decreased according as the rate of data items fed to the buffer store 24 increases/ decreases. N data items are read-out at a time from the buffer store 24. In this way the central processing unit does not have to wait an inordinate time before a data item may be operated on, as the copy of the data item is transferred from the buffer store 24 to the non- volatile store after at most the predetermined time (which may be 1 second). The Nth output of the counter 26 and the output of the clock generator 28 control the read-out of the buffer store 24 via an OR gate 30 and a buffer store output register 32. If the Nth output of the counter 26 is produced before the output of the clock generator 28, the value of N is increased via an AND gate 36. In the opposite case, the value of N is decreased via an AND gate 34 Circuitry 38, 40 coupled to the AND gates 34, 36 maintains the value of N between predetermined limits. The system is a multi-processing system handling concurrent transactions from a plurality of peripheral devices, the buffer store circuitry being microprogram controlled. Alternatively, the buffer store operations may be controlled by software. Variable length or fixed length data items may be used. The main store may be a disc store and the non-volatile store a disc store or a tape store.

Title: Gas plating with copper acetylacetonate
IPC: C23C16/18
Filed: 1954-10-01
Abstract: 768,378. Coating with copper. COMMONWEALTH ENGINEERING CO. OF OHIO. Oct. 1, 1954, No. 28301/54. Class 82(2) In a process of coating a metallic object with copper, the object is heated to a temperature of 500‹-600‹F. and contacted with gaseous copper acetylacetonate in an atmosphere containing a non-reactive carrier gas for a time sufficient to cause decomposition of the copper acetylacetonate and deposition of copper on to the object, said atmosphere being at atmospheric pressure and at a temperature of 300‹-450‹F. The carrier gas may be an inert gas such as argon or helium, or other non-reactive gases such as nitrogen and carbon dioxide. As shown, carbon dioxide, contained in tank 24, is passed to coil 19 submerged in oil maintained at 300‹-450‹F. thereby attaining a temperature in the same range. The heated carbon dioxide then passes into carburetter 13, which contains granules of copper acetylacetonate, takes up vapours of said acetylacetonate and flows to nozzle 2, whence it expands into chamber 1 wherein the copper acetylacetonate decomposes to deposit copper on to the metallic object 3, said object being maintained at a temperature of 500‹-650‹F. by resistance heating element 16. The coating of steel and cast-iron workpieces is referred to.

Title: Improvements in or relating to arrangements embodying charge storage pick-up tubes
Inventor: ODDELL LEONARD GEORGE
IPC: H01J31/26
Filed: 1962-07-24
Abstract: 975,855. Television pick-up tubes. ELECTRIC & MUSICAL INDUSTRIES Ltd. July 24, 1963 [July 24, 1962], No. 28434/62. Heading H1D.  In a charge storage pick-up tube having a first photo emissive surface 2, Fig. 2 or 4, on which an optical image is formed (e.g. by lens 6, Fig. 2), a light-transparent target 3, and a second photo-electric surface 4 on the side of the target remote from the first electrode, a scanning light beam is focused (11) on to the second photo emissive surface 4 through the target 3, in Fig. 4 after reflection at 15. Electrons from the first photo-electric surface 2 are focused on to the target by the electro-static lens 7, 8, or magnetically; photo-electrons from the second photo-electric surface 4 are accelerated by the mesh 5 and fall either on to the aluminized phosphor 12 or on to an electron multiplier. The scanning light beam may enter the tube through the first photo emissive surface 2, Fig. 2, either by being of a wavelength to which this surface is not sensitive, or by being very out-of-focus at this surface; or the beam may enter through the part of the end window adjacent the phosphor screen and reflected back through the target, or through a window in the side of the tube. The mesh 5 may be employed as a stencil in the formation of the mosaic 4, the mesh being close to the target during evaporation of the photo emissive layer on to the target, and then being drawn away from the target; in this way the mesh is itself substantially non-photo emissive on the side facing the scanning light.

Title: Improvements in or relating to the production of cellulose acetate filaments
IPC: B29C48/05
Filed: 1939-10-23
Abstract: 534,243. Artificial filaments. HERCULES POWDER CO. Oct. 23, 1939, No. 28515. Convention date, Nov. 30, 1938. [Class 2 (ii)] Thin filaments of cellulose acetate are obtained by heating cellulose acetate rapidly to a plastic state in the absence of solvents or plasticizers, extruding the plastic cellulose acetate into filaments and subjecting them to stretching and rapid cooling. The operation may be effected in an inert atmosphere. Cellulose acetates of various acetyl values and viscosity characteristics may be used. The cellulose acetate should not be allowed to remain in the heated state for a long period in view of the tendency for depolymerization at high temperatures. In no case should the conditions of time and temperature be such as to cause a decrease of the specific viscosity of the cellulose acetate of more than 50 per cent. Before heating the cellulose acetate, air may be removed by subjecting it to a vacuum or by flushing it with an inert gas e.g. nitrogen, argon, or carbon dioxide. The cellulose acetate may be heated to 425-520F. As shown in Fig. 1, cellulose acetate is fed down hopper 1 into extrusion chamber 5 and is caused to pass through a rising current of inert gas introduced through perforations 4. The material is compressed and forced along the cylinder by piston 6 and is heated and rendered plastic by means of induction by electric currents in the coils 9, 10. The current in the coils may be regulated thermostatically with the aid of thermocouples 12, 13. The plastic material is extruded through the orifice 14. In another construction, there is used instead of the piston 6, a conveyer screw tapering towards the orifice and operating in a similarly tapering extrusion chamber. The extruded cellulose acetate filament may be cooled by a current of cool gas in chambers 17, 18, Fig. 3, and may be stretched by means of the winding reel 19. The cellulose acetate may be pre-heated in the hopper 1. It may be closed and partially evacuated to remove air. The cellulose acetate may be fed to the extrusion chamber by a screw device. The piston 6 may be replaced by one working on the screw-jack principle. Heating of the chamber may be effected not only by electrical induction but by electrical resistance elements or by hot oil or steam. The cellulose acetate may be heated more effectively by breaking up the path of the material into a number of passages in that portion of the extrusion chamber nearest the orifice. The orifice may be circular, oval, straight, or annular. The Specification as open to inspection under Sect. 91 comprises also the production of fibres from cellulose acetate in a heated plastic state by use of a revolving disc or a high velocity heated stream of gas. Instead of thin filaments there may be produced artificial horsehair or bristles. This subject-matter does not appear in the Specification as accepted.

IPC: B29D5/02
Filed: 1931-10-17
Abstract: 391,146. Sliding-clasp fasteners. CORNER, G. H. C., BROWNSDON, H. W., Lion Works, Witton, Birmingham, and IMPERIAL CHEMICAL INDUSTRIES, Ltd., Millbank, London. Oct. 17, 1931, No. 28907. [Class 44.] In the manufacture of sliding-clasp fasteners in which the fastener members are moulded, cast, stamped or otherwise produced from non-metallic material such as artificial resin, the members are made separate from the stringer, singly or in rows, and are then secured to the stringer by adhesive, or by softening the stringer-embracing jaws of the members by heat or solvent. The invention is applicable to members of any form, and the slider may be metallic or of non-metallic material similar to that of the fasteners. Materials given as suitable for formation of the members are cellulose ester or ether material or resinous polymerized unsaturated organic compound, phenolaldehyde resin, urea- or thiourea-aldehyde resin, polyhydric-alcohol-polybasic-acid resins, or compressed impregnated paper, fibre, or the like, the material being selected according to the required strength, durability, &c. Hardening of the resin, when possible, may be effected at any desired stage of the manufacture. An example is described in which the members are cast &c. on the edge of a steel tape, which is then removed and replaced by a fabric tape impregnated or coated with cementing material. A suitable cementing composition mentioned is a strip of plasticized cellulose benzyl ether softened by heat or solvent and rolled &c. into the pores of the tape. Alternatively, a solution of the above ether may be used. The use of a stringer with beaded edge is not essential.
