Title: Method of producing a velvety surface on flexible bases of plastic compositions
IPC: D04H11/00
Filed: 1947-12-31
Abstract: 649,120. Fibre coated plastic sheets. BERNSTEIN, G. Dec. 31, 1947, Nos. 35210 and 35211. Convention dates, March 25, 1946 and Feb. 14, 1947. [Class 93] In a hot calendering method of obtaining a velvety surface upon a flexible base made by hotcalendering of plastic composition, the fibres are first distributed upon a moving auxiliary surface which deposits them upon the sheet of plastic composition as it is rolled out by the calender, the whole being then compressed by means of a lateral or supplementary cylinder co-operating with a lower cylinder of the calender. The fibres distributed upon the auxiliary surface may be sprinkled with an adhesive solution or suspension (e.g. rubber solution or latex) before being brought into contact with the base of plastic composition. Referring to Fig. 1 endless vibrating band 5 carries the fibre b delivered to it from hopper 7 between cylinders 2 and 3 to which is fed the plastic sheet a (rolled out between heated cylinders 1 and 2, 2 being the hotter) which gathers the fibres and undergoes compression in rings 2 and 3 and then passes between cylinders 3 and 4 where the other side picks up fabric 9. The coated fabric may be vulcanized or matured, emery papered and brushed. In Fig. 2 the fibres are dropped on to endless band 20 from sifter 12 and sprayed with adhesive from atomizers 15 led between cylinders 3 and 4 where they meet plastic sheet 29 which has been rolled out by cylinders 1 and 2, and then backed with fabric 26 between cylinders 2 and 3. The fibres are forced into the plastic between nip 3 and 4, brushed at 18 and wound at 17 after which vulcanization may be carried out.

Abstract: 945,726. Nuclear fuel. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Sept. 27, 1962 [Oct. 2, 1961], No. 35572/61. Drawings to Specification. Heading G6C. A nuclear fuel composition is prepared by heating a mixture of iron oxide and fissile material oxide to melt a substantial proportion of the mixture, crushing the resultant mass, reducing the iron oxide content to metallic iron and then forming a compact of the iron and fissile-metal oxide. Before compacting, e.g. at 2 tons/sq. ins at 1150‹C. for 1 hr, metallic iron powder may be added to the mixture to give the desired final composition. The initial oxide mixture is selected so as to contain more fissile material oxide than the eutectic composition, e.g. it contains 70%-90% by weight of UO 2  or from 50 to 90% by weight of PuO 2 . After heating, the mixture is cooled slowly to produce fissile material oxide particles in the size range 200Á to 300Á. The reduction of the iron oxide is effected by heating to 1000‹C. to 1100‹C. in hydrogen.

A prefabricated building, e.g. of reinforced concrete, is composed of full height external panels 1, the adjacent edges of which are flanged at 5 and 6, Fig. 10, to interfit, provided with Z- section corner posts 9, Fig. 4, and to which internal division panels 2 with T-head edges are bolted, the panels 2 having vertical halved joints to make smooth internal division walls. The top edges of the wall panels 1 also have flanges 7, Fig. 2. The roof slabs 3 are provided with upstanding flanges 20 at each edge, Fig. 14, which abut the adjacent flanges of the next roof panel to which they are bolted through holes 21. The length of a roof panel is the same as one dimension of a room, the other dimension being a multiple of the width, of a roof panel. To secure the roof slabs in position they have corner recesses on their underside to accommodate dowels 22 which engage in recesses 17 in flanges 16 at the top edges of the internal divisions 2 and with bolt holes 8 in the external wall panels 1. The roof panels 3 have within the corners of the building dependent flanges 24, Fig. 13, to fit over the top flange of the wall panels 1. The roof slabs 3 which form eaves with the external wall panels 1 have an overhanging extension integral eave 23, Fig. 12 (not shown), and 13, to throw rain water clear of the walls. Independent eaves 26, Fig. 15, for the ends of the building are bolted at 27 to the flanges 20 of the roof panels 3. Such eaves have bracing fins 25. All the eaves are abutted by tongue and groove joints. Corner eaves have extensions 30, Fig. 12 (not shown), with 45 degree edges to abut and complete the overhang at the corners. Alternatively the roof may be secured to wall plates, Fig. 22 (not shown). For heat insulation in hot climates the upper ends of the flanges 20 of the roof slabs 3 are rebated at 31 so that a flat panel 32, Fig. 14, spaced from the slab 3 may be supported therein.

Abstract: 788,417. Automatic gramophones. STAAR, M. Dec. 14, 1955 [May 27, 1955), No. 35903/55. Class 40 (2). In a record player a record urged horizontally into position on the turntable causes starting of the motor and centring of the record prior to causing the release of the tone arm and placing of the stylus in contact with the record. The various movements and operations are controlled by a multi-armed lever 11 pivoted at a fixed point 12. When a record D is passed horizontally on to the turntable, its edge encounters an upstanding pin 10 on the lever 11 and moves it over the dead centre of a spring 19 so that the lever 11 moves from the position shown in Fig. 2 to that in Fig. 3. The position of the record itself is registered by a two-armed stop member 65. The initial movement of lever 11 closes contacts 16<SP>1</SP> to start the motor and, by means of the slotted arcuate portion 22, lifts the locating centre member 29 from the position shown in Fig. 10 to that in Fig. 11. An arm 57 fixed to the pin 10 carries a brush 56 at its end and during this movement cleans the stylus point. During the latter part of the movement of lever 11, a ramp 31 thereon permits a pin 32 engaging it to be lowered on to the record. The final movement of the lever 11 brings the pin 10 into engagement with the forked part of a member 61 to move one of its limbs out of the path of a member 45 carried by the tone arm 5, and thus permits the stylus to traverse the record. At the end of the playing of a record an interceptor lever 48, which has been advanced during playing by a pin 46 on member 45 and is mounted pivotally at 51 on lever 11, engages the toothed wheel 4 on the turntable shaft, causing the lever 11 to be swung back to its initial position, thus breaking the motor circuit, lifting the stylus, returning the tone arm and ejecting the record from the turntable by means of the pin 10. The brush 56 also carries out a further cleaning operation.
