Title: Process for recording information
IPC: C08F2/00
Filed: 1965-08-06
Abstract: 1,108,067. Modulated light. INTERNATIONAL BUSINESS MACHINES CORPORATION. 6 Aug., 1965 [2 Sept., 1964], No. 33696/65. Heading H4F. [Also in Division G2] A process for recording information in the form of surface deformations in a polymeric thermoplastic material comprises applying to a surface of the material an electrostatic charge pattern having a field intensity distribution representative of information required to be recorded, the thermoplastic material being of such a nature that its surface is spontaneously deformable at room temperature upon application of the electrostatic charge pattern. These polymers either have a glass transition temperature (g.t.t.) below room temperature, or are copolymers of at least two monomers whose homopolymers have a g.t.t., (1) below and (2) above room temperature respectively, or are polymers which have been degraded to have a g.t.t. below room temperature, or, finally, include a compatible plasticizer to so reduce the g.t.t. long lists of all these are given. Backing material for the recording material may be either a flexible composition or a rigid inflexible material, polyethylene terephthate, polycarbonate resins, glass, unsaturated polyester resins and metal being specified. A conducting layer may be deposited between the thermoplastic surface and the backing so as to aid the erasure step. In a typical example, (1) a styrene-isoprene copolymer mixed with a terphenyl is deposited on a polyethylene terephthate film and the film placed on an etched stainless steel electrical ground plane whose pattern consists of a grid network of lines with a line density of 250 lines per inch. The composition is charged by a corona discharge to 1300 v., the charged film turned over, insulated from ground by inch air, and charged oppositely to the same voltage, the deformations then appearing.

Abstract: - 371,302. Parachute apparatus. BRADLEY, J. E., 3209, South State Street, Chicago, U.S.A. Dec. 4, 1931, No. 33722. [Class 4.] Parachutes B f o r breaking the fall of an aeroplane are stowed in a folded condition in chambers 1 on either side of the fuselage A, their rigging lines being connected to the fuselage sides, as at 7. Partitions 10 arranged in the canopies form chambers 11 therein which may be inflated by tubes 12 engaging the outlet pipes 3 of tanks 2 containing compressed air or other fluid. Valves 4 on the outlet pipes have operating cords connected to a single lever in the cockpits ; when this is actuated the pressure fluid causes projection of the parachutes through openings 8 in the fuselage sides and also ensures inflation of the canopies. The chambers 11 of the parachutes are stated to provide emergency on water as the water closing the ends of the tubes will prevent the escape of the air or other fluid therefrom. Any number of parachutes may be employed.

Title: Improvements in the preparation of uranium hexafluoride
IPC: C01G43/06
Filed: 1957-11-12
Abstract: Uranium values are extracted from aqueous acid solutions having a pH of 0.1 to 3.0 with a uranium-complex-forming material, which is substantially insoluble in the aqueous acid solution, dissolved in an organic diluent which is inert to and immiscible with the aqueous acid solution, the concentration of uranium in the aqueous acid solution being such that the solution of the uranium-complex-forming material becomes saturated with uranium. The uranium values are then removed from the extracting solution by stripping with concentrated hydrochloric acid, acid is evaporated from the stripping solution, and the resulting solution of uranium oxychloride is treated with ammonia to precipitate ammonium diuranate, which is dried and reduced to uranium dioxide with hydrogen gas.  The uranium dioxide is then cooled in a nonoxidising atmosphere, and hydrofluorinated with hydrofluoric acid to uranium tetrafluoride, which is dried and heated in an inert atmosphere to form anhydrous uranium tetrafluoride, which is reacted with fluorine to form uranium hexafluoride, which is recovered by distillation.  In an example, "yellow cake", i.e. a uranium concentrate containing chiefly sodium ammonium diuranate, was dissolved in hydrochloric acid and extracted with di(2-ethylhexyl) phosphoric acid in kerosene.  Other suitable complex-forming agents are dialkyl phosphates, phosphoramides, phosphonates, and monoalkyl or dialkyl amines which are soluble in the organic diluent.  Suitable organic diluents include aliphatic hydrocarbons, for example naphtha or heptane. Specification 856,827 is referred to.
