Title: Improvement relating to roof and floor coverings
IPC: E04D5/10
Filed: 1963-08-14
Abstract: A sheet roofing or flooring material is produced by coating on one side a lamination of thin thermoplastic or rubber sheeting between outer sheets of paper, fibre or foil, bonded and embossed together under heat with a relief form as for example dimpled, globular, noduled, fluted, reeded, grooved, or similar continuous open form, with bitumen, tar, mastic, rubber, or other roof water-proofing substance.  The embossed sheet may consist of a lamination of polythene or similar thermo plastic sheet e.g. polyvinyl chloride, between sheets of paper, embossed under heat. The laminated, bonded and embossed sheet may be passed through a bath of bitumen or similar waterproofing liquid to coat the sheet lightly on both sides while still retaining the embossed form. The sheet material having a coating on one or both sides may be combined with another sheet of flat waterproof material while the coating substance is in an adhesive state.  The embossed sheet may be united to ordinary bitumen saturated roofing felt during manufacture by pressing the two together while the bitumen is still wet and adhesive.  The sheet material may be resistant to chemical or biological attack, and may be elastic and ductile. The flat sheet united to the embossed sheet may be wider than the latter thus forming an edge for overlapping adjoining sheets when laid on a roof or floor.  The sheet material may be pierced or punched with holes at intervals.

Filed: 1947-12-09
Abstract: 642,439. Gravity-separation apparatus. STEVENS, A. H. (Graver Tank & Mfg. Co., Inc.). Dec. 9, 1947, No. 32443. [Class 46] A tray clarifier includes trays made from plate material having progressively - increasing slope from the horizontal plane and being peripherally supported and so spaced that the clarification zones between them are wider than they are deep. Scrapers having lower edges corresponding with the shape of the trays are also provided. As shown in Fig. 1, each tray comprises a frustospherical or ellipsoidal part 16, having a radius of curvature approximately equal to its peripheral diameter, and a depending skirt 17, joined by a knuckle portion 18 having a radius of curvature of about 1 per cent of that of the part 16. The trays are spaced vertically to provide narrow slots 23 and from the tank wall 11 to provide an annular channel 22. Angle-section scrapers 28, conforming to the tray curvature, are provided. Liquid to be clarified enters by a pipe 30, a fixed cylinder 39 surrounding a rotatable shaft 24 and then passes through a cylinder 38 attached to the shaft 24 into a flocculating compartment 20 from which scum is removed through an outlet 34 by a freely-swinging skimmer blade 35 attached to a rotating arm 36. The liquid then passes via channel 22 and slots 23 into clarification compartment 21. while solids deposit finally in a mud-conditioning chamber 42. A relatively small unflanged mud-conditioning tray 40 may be provided. The end closures 12, 13 of the tank 10 have a shape similar to that of the tray-heads 16. In the modification of Fig. 2, which may be operated under pressure, a separate compartment 55 is provided, above the main tank 50, from which scum is withdrawn through a pipe 62, and from which the liquid flows through slots 59 down the inside of a rotatable tube 52, which takes the place of the shaft 24. The liquid is expelled through slots 60 into a flocculating chamber 42. in which it is stirred by fingers 66 attached to a mudconditioning tray 40 and scrapers 28B rotating with the tube 52 under a fixed scraper 68. The movement of the liquid is thereafter upward. For relatively large internal tank pressures, the knuckle radius of the closures 12, 13, 57, 58 should be about 3 per cerit of the main radius of curvature. Specifications 500,896, 635,285, and U.S.A. Specification 2,336,659, are referred to.

Title: Improvements in electrical connectors of the plug-in type
IPC: H01R13/428
Filed: 1954-11-10
Abstract: 761,028. Two-part couplings; plug boards. GENERAL ELECTRIC CO. Nov. 10, 1954 [Dec. 1, 1953], No. 32568/54. Class 38 (1). A tubular plug pin is removably held in an aperture 11 in a plug board 10 suitable for a computer, by a collar 14 and ears 27, 28 of a spring 19 of round, rectangular, or oval crosssection, which project through slots 22, 23, in the pin, and the ends 33, 34 of the spring bear against a conductor 16 crimped to the pin. As the pin is being inserted in the aperture the ears are forced inwardly by the walls of the aperture until the slots are again uncovered when the ears spring out and secure the pin. To remove the pin, the latter is pulled back- - wards until its end 13 abuts the nose 24 of the spring, Fig. 2, further pulling causing the walls of the aperture to depress the ears 27, 28, thus allowing the complete removal of the pin. In another embodiment (Fig. 4) the nose 64 of the spring abuts the conductor, and the limbs 69, 70 cross each other and have bent ends 71, 72 which, when the plug is withdrawn, are forced into contact with the inner wall of the tube and provide a fulcrum. In another form (Fig. 3, not shown), the ends of the limbs are arranged to come into contact with one another after a short initial pulling movement.

Title: Improvements in or relating to moderator core structures for nuclear reactors
Inventor: COX HARRY ALBERT
IPC: G21C5/08
Filed: 1959-09-25
Abstract: 898,434. Moderator structures. GENERAL ELECTRIC CO. Ltd. Sept. 14, 1960 [Sept. 25, 1959], No. 32703/59. Class 39(4). In a moderator structure comprising squaresection prismatic blocks of graphite mounted end to end in columns, the blocks are held in position relative to each other by a combination of corner keys and side face keys. The keys engage keyways formed either in the blocks themselves or in tiles disposed in layers between vertically adjacent blocks. These tiles 3, in the embodiment shown in Fig. 2, are provided with annular projections 7 which fit into recesses in the ends of the blocks 1, 2 to ensure the alignment of the fuel channels 5, 6 and they are formed with corner keyways 8, the bearing surfaces 10 of which are parallel to the diagonals of the tiles, and central side face keyways 9, the bearing surfaces 11 of which are at right angles to the side faces. Cruciform keys 12 and rectangular keys 13 are arranged within the appropriate keyways and are dimensioned so as to be spaced from the ends of the keyways. The arrangement is such that the tiles, and therefore the blocks, are keyed into position with clearances between adjacent columns. Expansion of the graphite blocks or tiles due to irradiation is therefore permitted. At the same time shrinkage from the same cause is also permitted without distortion of the lattice spacing since all active keyway surfaces are nearly radial with respect to the axis for each column of blocks. In an alternative construction, the tiles 3 and projections 7 are separate, the latter being formed as one continuous annular cylinder about which the tiles 3 fit closely. The keys, or keyways, need not extend the full length of the blocks (or tiles) and the cruciform type of key may be of a composite nature, comprising, for instance, two separate crossed rectangular-section keys. Certain of the side face keys may be formed integral with one of the blocks (or tiles) with which they are associated. Specifications 784,291 and 784,292 are referred to.

Title: Method of preserving royal jelly
IPC: A23L21/20
Filed: 1956-10-26
Abstract: Royal jelly, preferably taken direct from a bee-hive, is preserved by dissolving it in water, buffering the solution, e.g. with citric acid and trisodium citrate or disodium hydrogen phosphate, filtering the resulting solution and then freeze-drying it, e.g. at a temperature between -5 DEG  and -10 DEG  C. and a pressure under 50 microns of mercury.  The moisture content of the freeze-dried product may be brought to 0.1% or less, by weight, by subjecting it to a pressure under 5 microns of mercury and a temperature over 20 DEG  C.  Before the solution is filtered, lactalbumin or gliadin may be dispersed in it to stabilize its protein content.  The filtered solution is preferably dried in dark glass bottles, which are then filled with a dry inert gas and hermetically sealed.
