Title: Reversible cushions of rubbery sponge material
IPC: A47C27/14
Filed: 1952-03-12
Abstract: 710,456. Moulds for sponge rubber. UNITED STATES RUBBER CO.' March 12, 1952 [April 2, 1951], No. 6369/52. Class 82 (2) [Also in Group XIV] A reversible sponge rubber cushion, e.g. a pillow, is moulded in one piece with inclosed spaced parallel cavities 26, the ends of which are connected to the outer surface of the cushion by slits 24, 25 which permit withdrawal of the mould cores forming the cavities, and also serve as ventilating ducts. As shown in Figs. 1 and 8, the mould comprises two halves 10, 11 hinged together at 12, the latter being provided with filling and vent apertures 20, 19 and the former carrying cavity-forming cores 15 the ends of which are flattened at 16 to form the slits in the cushion. When the mould is closed, the upper ends of the cores contact' the inner surface of the mould 11. Alternatively the cores may not extend over the full depth of the mould so that the cushion has slits on one face only. As shown in Fig. 3, each mould part 30, 31 carries cores 34 or 37 which are flattened at 35 and rounded at their inner ends 36. When the two sets 34, 37 are aligned their height may extend up to half the mould thickness but, if they are staggered, they may be of greater height than half that of the mould. The cores 15 (Fig. 1) or 34, 37 (Fig. 3) may be carried in sets on separate sheet members adapted to be fitted to the mould parts to facilitate the moulding of different cavity patterns. As shown in Fig. 5, the cores comprise tubes 57, 58 of different diameters, the flattened ends of which rest in notches 61 in the lower mould half 50, the mould being closed completely when the part 51 is brought to bear on the part 50. The cushion surfaces may be flat or, as shown, convex. The hinges between the mould parts may be replaced by pin and hole connections. When the moulds are being heated, the cores should be disposed horizontally to diminish settling of the mix. The cores may be of polygonal or elliptical cross-section. Specifications 479,264, [Group V], 543,921, [Group XIV], 553,513, [Group V], and 572,166 are referred to.

Abstract: 754,738. Presses for disc records. LICENTIA PATENT-VERWALTUNGS GES. March 5, 1954 [March 10, 1953], No. 6498/54. Class 87(2) Relates to presses for the manufacture of gramophone disc records and is characterized by a working station at each side of the press, intermediate movable cross heads 13 forming a corresponding number of working spaces and a servicing table 6, 7 at each working station. In the embodiment of the invention as described there are four tables and four working spaces. The tables 6, 7 are fitted to the frame of the press at convenient levels for rolling the dies 3, 4 therefrom into the press. The hydraulically-operated piston 2 rises to press the dies against the upper abutment 5. When the press die 3 has been fully inserted and meets the abutment 8, a push-contact 10 is operated; similarly a push-contact 11 is operated by the die 4, and signals consequently indicate that the press is ready to be operated, or the insertion of the last disc may be made to cause the operation.

Abstract: 1,215,297. Cathode-ray tubes; transit-time tubes. NATIONAL RESEARCH DEVELOPMENT CORP. 5 Feb., 1968 [10 Feb., 1967], No. 6546/67. Heading H1D. In a discharge tube in which a portion of the electron stream from a photocathode 5 is trapped and transits back and forth through a drift tube 13 between a pair of mesh grid electrodes 8 and 9, gating pulses are applied to mesh grid 9 periodically permitting a sample of the stream to pass between deflection plates 16 to an output display screen 6 to provide a sequence of mutually displaced images of successive phases of a high speed event seen by the photocathode 5, the axial extent of the decelerating field provided by the electrode 9 being kept small, to minimize time dispersion effects. This result may be achieved by interposing between the drift tube 13 and the second mesh grid 9 a further, short, tubular electrode (21, Fig. 3, not shown) having, adjacent the mesh grid 9, a closed end provided with a slot, and held at a high positive potential with respect to the drift tube 13. Other, but less advantageous, arrangements referred to include the provision of a mesh grid across the end of drift tube 13, together with a reduction of the spacing of that tube from the mesh grid 9; and the provision of a further mesh grid, held at a small negative potential, disposed a fraction of a millimetre in the front of the mesh grid 9. The electron stream is accelerated by annular electrodes 14 and 17, and focused by solenoid 7. The tubular electrodes may be formed by conductive coatings on the tube envelope. The theory is discussed, and dimensions and operating data given.

When the floor is of reinforced concrete, each column H is formed at its upper end with an integral slab portion O which is formed integrally with the nearest grid beams and may slope upwardly, as shown in Fig. 5, or be disposed horizontally, as shown in Fig. 7. The main slab portion G of the floor is formed integrally with the beams. A concrete filling J may be provided over the slabs O. Alternatively, the slab G may extend across each column so as to leave a void between such slab and the corresponding lower slab O. When the slab is of steel as shown in Fig. 6, the cantilevers I and the steel slab portion O of each column are disposed above the level of the main part G of the floor which is arranged at the underside of the beams. In the arrangement shown in Fig. 3, the main columns M<1> are arranged at the points of intersection of the beams and are formed integrally at the upper end with a horizontal slab N which is disposed below the level of the main slab portion of the floor and is formed integrally with such slab portion. as shown in Fig. 10.
