Patent GB-785228-A (GB)
Title: Improvements relating to shell moulds and the casting of metal therein
IPC: B22C21/00
Filed: 1955-01-28
Abstract: 785,228. Making metal-casting moulds. GENERAL MOTORS CORPORATION. Jan. 28, 1955 [Feb. 18, 1954], No. 2623/55. Class 87(2). [Also in Group XXII] During casting, shell moulds are supported between a pair of refractory backup members made of an aqueous slurry comprising refractory oxides and refractory cement, and pressed inwards against the mould. The mould mix, e.g., resin-coated sand of 140 A.F.S. number containing 3 per cent phenol formaldehyde resin and ¢ cc. of liquidizer per pound of coated sand, is blown into the space between an electricallyheated pattern 10 and a member 24, and the shell 29 then pressed and cured by a heated press-head 30. The mould-halves 38, which may be glued together, and backing-members 40, are then clamped for casting between plates 44 in frames 42. Alternatively one backing- member may be mounted on a spring-loaded plate with the other carried on a pistonactuated cross-head. The backing-members are made from a slurry of ten parts of a refractory compound essentially of calcium aluminate cement, and grog of refractory oxides such as silica, alumina and magnesia, and two parts of water, which is cast on a pattern. The pattern may be a shell mould formed on the press head 30 and coated with a water-resistant coating such as shellac or varnish, or a non-shrinking material such as type-metal, plastic or rubber cast into the impression 32 of the press-head. Reference has been directed by the Comptroller to Specifications 700,989 and 761,694 [both in Group XXII]

Patent GB-713795-A (GB)
Title: Improvements in or relating to terramycin
Inventor: MCGUIRE JAMES MYRLIN
Filed: 1952-01-31
Abstract: Terramycin is produced by fermenting an aqueous nutrient medium under submerged aerobic conditions by means of the organism streptomyces platensis NRRL 2364, a description of which is given.  A temperature of 24 DEG  to 30 DEG  C., preferably 27 DEG  C., and a fermentation period of 2 to 7 days, preferably 4 days, are employed.  The nutrient medium contains a source of carbohydrate, e.g. starches, glycerol and sugars such as glucose, dextrose and sucrose; a source of nitrogen, e.g. ammonium sulphate, soybean meal, cottonseed meal, casein or digests thereof, wheat gluten and lactalbumen; mineral salts, e.g. sodium chloride, sodium nitrate, potassium phosphate, potassium dihydrogen phosphate and magnesium sulphate; growth promoting substances, e.g. yeast extract and distillers solubles.  The terramycin may be recovered by acidifying the broth to e.g. pH2 with e.g. hydrochloric acid, filtering off the solids, and treating the filtrate with (a) adsorbent such as activated carbon, or (b) an immiscible solvent such as butanol.  In the example, the filtered broth is adjusted to pH9 with sodium hydroxide, and extracted three times with n-butanol.  The extract is concentrated azeotropically to an aqueous residue from which the terramycin is precipitated and is filtered off.  The terramycin is purified by countercurrent distribution of an aqueous solution at pH3 using a mixture of equal volumes of wet butanol and hydrochloric acid of pH3 saturated with butanol.  Specification 684,417 is referred to.
Patent GB-732700-A (GB)
Title: Radiation detector
Inventor: MUNDAY CHARLES WALTER
IPC: G01N21/37
Filed: 1953-01-30
Abstract: 732,700. Temperature-responsive actuating- elements. DISTILLERS CO., Ltd. Jan. 26, 1954 [Jan. 30, 1953], No. 2662/53. Class 64 (2). [Also in Group XL (b)] A radiation detector comprises a chamber, one wall of which is transparent to the radiations, e.g. infra-red radiation, a facing concave reflecting wall, a flexible diaphragm in the reflecting wall which is moved by pressure changes in the chamber, and means for measuring the movement of the flexible diaphragm. As shown, the chamber has a window 2 of quartz, rock salt, glass, fluorite, silver chloride or other material chosen according to the radiation to be transmitted. Opposite the window is a concave surface 3 which may be inserted or may be the wall of the chamber ground and polished. The concavity of this surface is such as to direct the radiation on to a mirror 4 in the middle of the window and again to concave reflector 3. Absorption of radiation in the chamber causes expansion of the gas in it and deformation of a flexible diaphragm  6 which may be of aluminium, gold or platinum, or plastic which may bear a metal film. Movement of the diaphragm is detected by associating it with a fixed electrode 8 so that the capacity between the two electrodes varies. To prevent zero errors due to pressure differences between the chamber and its surroundings, a capillary leak is provided. The movement of the diaphragm may also be detected as the deflection of a light spot reflected by the diaphragm observed either optically or electrically.

Title: Memory storage device and method of making the same
IPC: G11C13/04
Filed: 1973-01-18
Abstract: 1362148 Read only stores J FAJANS 18 Jan 1973 2669/73 Heading G4A Information is stored in a three dimensional store 50 (Fig. 1) by directing pulses of radiant energy on to a body of material to produce a network of decomposed portions within the body. As described a ruby or gas laser 12 is pulsed with the information to be stored to direct a pulse of radiation via filter 32, lens 34, aperture 38 in a steel sheet 36 and lens 40 on to a block of polymethyl methacrylate which is carbonized at the focal area of lens 40. Hand wheels 16, 18, 20 are used to move the block of plastics in three directions between radiation pulses. The stored information is read by directing light from a lamp (62, Fig. 3, not shown) via aperture (66) and lens (40) on to the block (50), transmitted light being passed via lens (68) and shutter (74) (comprising a motor driven slotted disc), aperture (72) to a photomultiplier tube (78). Hand wheels permit the block to be moved so that light at the focus of lens (40) scans the stored information. Instead of plastics material, glass or quartz, in which cracks are formed by the radiation pulses, may be used.

Title: Improvements in and relating to the manufacture of net-like fabrics of plastic materials
Inventor: WINCHCOMBE JOHN JEREMY
IPC: B29C48/05
Filed: 1965-01-21
Abstract: A polyurethane is made by mixing (a) a prepolymer of hexamethylene diisocyanate, 2700 gm., and an hydroxyl terminated adipate polyester of butane diol and glycol, 1000 gm., and (b) 1,4-butane diol 225 gm., trimethylol propane 225 gm. and stannous octoate 10 gm.  The mixture of (a) and (b) is extruded to form a net (see Division B5).  The compositions (a) and (b) are made by fresh-mixing the individual ingredients.ALSO:A net-like fabric of a plastic material is made by moving at least two relatively fixed spaced dies through a predetermined distance in a direction substantially at right angles to the direction of motion of a support surface positioned below the dies, continuously moving the support surface whilst extruding continuously a plastic material (as defined below) through said dies whereby extruded material is deposited in strip form on the support surface, reversing the direction of motion of said dies whilst continuing movement of the support surface and extruding the material whereby extruded material is deposited in strip form on the support surface, so that after said reversal of motion of the dies, at least one strip, as it is deposited, crosses at least one other strip deposited prior to said reversal of motion, whereby a net structure having an open-mesh is produced, and removing this structure from the support surface.  The term "plastic material" as used herein means; a substantially dry, vulcanisable natural or synthetic rubber composition capable of extrusion and which is self-tacky in the unvulcanised state; a solution or dispersion of natural or synthetic rubber which solidifies on removal of the solvent or by coagulation and drying; a synthetic thermoplastic composition capable of melt or compression extrusion through dies and settable by cooling, which is self-tacky prior to being fully set; a thermosettable resin composition capable of extrusion and which is self-tacky prior to being fully set; and a wet, spinnable, regenerated cellulose-producing composition or a protein fibre-producing composition settable by coagulation.  A polyurethane composition is specifically exemplified.  The dies preferably move at constant speed producing a diamond-mesh net.  Suitable apparatus is illustrated in Figs. 2 and 3 (not shown).
