Title: Improvements in or relating to sound records
IPC: G11B3/70
Filed: 1930-06-19
Abstract: In the manufacture of laminated sound records having a paper, fabric, or other fibrous core, the core is waterproofed by impregnating it with a resin soap and then precipitating the resin on the fibres by immersion in an acid bath.  Any saponifiable resin, such as common rosin, shellac, acaroid resin, copal or kauri gum, may be used. Small quantities of agents such as stearic acid may be added to the resins before saponification, to prevent stickiness and to increase the water-resisting property. A resin soap solution may be prepared by adding rosin to boiling sodium hydroxide, excess of alkali being partly neutralized by hydrochloric acid.  Sheets or discs of paper, linen, &c., are soaked in the soap solution, and after being squeezed between rollers they are immersed in dilute acid preferably hydrochloric acid.  The sheets are then washed and dried.  They may, if desired, be pressed under heat, before being used for making record blanks by applying to the core a material such as cellulose acetate or celluloid in disc or powdered form.

Title: Hierarchial storage system for an electronic computer
IPC: G06F12/12
Filed: 1974-05-01
Abstract: 1425804 Memory systems INTERNATIONAL BUSINESS MACHINES CORP 1 May 1974 [4 June 1973] 19025/74 Heading G4A In a hierarchical memory system including a large-capacity low-speed backing store and a plurality of buffer memory levels of successively smaller capacity and higher access speed, the fastest being responsive to a CPU, each memory level having an associated mapping store for indicating the location and identity of altered and unaltered segments of pages (complete pages being held in the backing store), when a request for data is made by the CPU to all the memories, the path is cleared between the lowest level store containing a request segment and the level communicating with the CPU and a complete page is transferred along the path. As described, the address in the backing store of a requested segment of data is passed via address switch 42 (Fig. 5A) to address search block 13 of the backing store in all hierarchy levels, the search result being fed to circuit 13A. AND gate 15 of the fastest level responding is enabled to trigger circuit 16 to provide the address of the page frame in the buffer holding the segment. A signal is then fed to all faster levels to effect their replacement page frame algorithm to determine their most expendable page so that a path may be cleared. If the expendable data has no page marker (a marker indicating that the data has been altered) circuit 26 assigns the selected frame as a data path step and when all faster stores similarly respond, the page containing the data is transferred forward to the fastest store under the control of the circuit 30 (Fig. 5B) a signal on lead 32A of the receiving store updating its associated mapping store. If however any of the expendable frames of data has a marker then the parent page may be updated before it is destroyed. In this case the address in the backing store of the expendable data is supplied on lead 10A and the selected page frame is transferred towards the store containing the amended page semgent. When it is in the adjacent store, the segment is transferred to the slower store and the markers in the faster and slower stores are then reset and set respectively. In this manner a " cleared as needed " operation is effected. In a second embodiment (Fig. 6A, 6B not shown) a " clear path memory " operation is effected in which a clear path through the entire length of the memory is made available, a path of expendable page frames being re-established to all levels following each page transfer to the high speed store. If one of these expendable pages is selectec by the CPU it is removed from the path.

Title: Improvements in or relating to the production and utilisation of pro-oxidants
IPC: C11B3/12
Filed: 1938-06-27
Abstract: 516,476. Pro-oxidant oil fractions ; driers for paints. FAWCETT, E. W., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 27, 1938, No. 19055. Drawings to Specification. [Classes 91 and 95] Concentrates for accelerating oxidation of unsaturated organic compounds e.g. the drying of oils, paints and varnishes, are obtained by subjecting a natural triglyceride oil or fat containing pro-oxidants to high vacuum, preferably. short-path, distillation at a pressure below 1 m.m. under such conditions as to obtain one or more small very volatile fractions containing (1) the greater part of the prooxidants substantially free from anti-oxidants: or (2) both pro- and anti-oxidants, the fractions then being treated chemically or physically to separate a pro-oxidant concentrate. The prooxidant concentrates may be further purified e.g. by distillation, preferably high-vacuum short-path, solvent extraction, fractional precipitation from solutions, or chemical means. Specified oils containing pro-oxidants are cottonseed, soya, arachis, linseed, and other vegetable oils. In an example, crude cottonseed oil is treated in a vertical-surface shortpath high-vacuum still in which the evaporating surface is heated to 225‹C, the pressure is 3-5 x 10<-3> m.m., and the evaporating and condensing surfaces are 0.5-1.0 in. apart. A red oil, which is a mixture of anti- and pro-oxidants and constitutes 5.4 per cent. of the oil treated, collects on the condensing surface, while a yellow mobile liquid, which contains most of the pro-oxidants and constitutes 0.2 per cent. of the oil treated, collects in a vessel cooled to -80 ‹C. placed between the still and the vacuum pump. The drying of soya bean oil is considerably improved by adding the pro-oxidant fraction in the proportion of 0.15 per cent. The red oil may be treated to recover its content of prooxidants e.g. (1) by short path high vacuum distillation at 3-5 X 10<-3> m.m. in a falling film type still; the distillates up to 90‹C. are practically free of anti-oxidants, those above contain mainly anti-oxidants ; or (2) by dissolving in aqueous alcohol or acetone and extracting the pro-oxidants by petroleum ether. Specification 501,194 is referred to.
