Abstract: 1,250,351. Pipe couplings. B. T. F. EKMAN. 14 Nov., 1968, No. 54007/68. Heading F2G. In a quick-release coupling comprising socket and spigot parts 1 and 2, each containing a spring-closed valve member 13 which is opened automatically by abutment with the valve member of the other coupling part on connecting the coupling parts, each valve member contains a spring-loaded pilot ball valve 20 which closes a valve through passage 17, 24, 22 when the coupling parts are disconnected and which is automatically opened on coupling of the parts to relieve any pressure differential existing across the coupling parts prior to valve members 13 opening. The ball valves may be unseated by pins 19 on coupling. Alternatively, the pins may be replaced by a pair of balls, Fig. 3 (not shown). The outer end of the socket is provided with a first sealing ring which seals the interspace between the coupling parts on their initial engagement prior to the pilot valves being opened. A further supplementary sealing ring is also provided. Each main valve member 13 is guided in a sleeve 12, and a spring 23 biases both the main valve member and pilot ball valve to the closed position. The coupling parts are latched together by balls 11, which are retained in a recess in the spigot part by a locking sleeve 10, which is itself axially retained in position by a spring 9 and a sleeve 5 releasably held in position on the socket part by balls 6. Rotation of sleeve 5 on balls 6 moves the sleeve towards abutment 8 and permits the quick drawing back of sleeve 10 to allow disconnection of the coupling parts.

Abstract: The support structure of a bed comprises a preformed head portion (10) and a preformed foot portion (11). These portions are hollow, and at least one of them contains a drawer affording accessible storage space. The portions are linked by means such as bars (31) enabling the portions to be assembled and disassembled at will. The bars have pins (34) entering complementary bushes in the end portions so that the bars can be simply lowered into position to effect assembly. One or more additional drawers may be provided between the head and foot portions and open laterally of the bed. The additional drawer or drawers may be supported on rails (35) on the head and foot portions. <IMAGE>

Abstract: 1,251,293. Treatment for sized fibres for reinforcing elastomers. ESSO RESEARCH & ENG., CO. 19 Feb., 1969 [14 March, 1968], No. 9033/69. Heading DIP. A treatment for fibrous materials which are to be used to reinforce elastomers comprises coating the sized fibres with a cement of a vulcanisable rubbery organic polymer and treating the coated fibres with a non-solvent for the rubbery polymer. In a preferred embodiment the coated fibres after emerging from the non-solvent are wound into a cord whilst still wet. Non-solvents produce a moist tack-free surface on the fibre while coated strands are fabricated into cords, but do not interfere with the tack of the dried coating. The non-solvents may be chosen from C 1  to C 4  aliphatic alcohols, C 3  to C 5  ketones, water, mixtures thereof and n-hexane. The vulcanisable rubbery organic polymer may be a natural rubber, a synthetic straight chain C 4  to C 8  butadiene derivative or a copolymer of these with each other or with acrylates, styrene isobutylene, acrylonitrile or chloroprene, or ethylene-propylene copolymers or ethylene-propylene-diene terpolymers. In the examples combinations of rubbery polymer and non-solvents are butadiene-styrene copolymer with isopropylalcohol, acetone or water; 90/10 blend neoprene-natural rubber with n-hexane; 75/25 acetone/water, 90/10 acetone/water or water; natural rubber with water; and butyl rubber with water. The fibrous material may be glass.

Abstract: 1,264,467. Turbomachine rotors. ROLLSROYCE Ltd. Sept.9, 1969 [Sept.20, 1968], No.44948/68. Heading F1T. A hollow drum type bladed rotor, e.g. for the compressor of a gas turbine engine is evacuated so that in operation it is strengthened by increased compressive forces acting on the drum. The latter comprises a series of bladed portions 17 lightly welded together at 20 and also bolted at 21. Axial compressive forces are applied to opposite ends 25 of the drum by fixed bellows 26 which are supplied through pipes 27 with air at compressor discharge pressure. During manufacture the interior of the drum is evacuated through a hole 23, which is then sealed by a plug 24, so that during operation the differential pressure between the exterior and the interior of the drum causes radial compressive forces to be applied to the drum in opposition to the centrifugal forces.

Abstract: 1,264,759. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 24 March, 1970 [31 March, 1969], No. 14110/70. Heading H4K. In a stored programme controlled tollswitching exchange, data in respect of a plurality of peripherals e.g. incoming/outgoing junctors, senders, receivers or lines, is stored in blocks in a first temporary memory TM2 while simultaneously other blocks of data in respect of another plurality of similar peripherals stored in a memory TM3 are processed and the results of processing are stored in a relevant portion e.g. TM12 of a main memory TM1. Once the processor PCU has provided a start order on lead so to a mini programme TACU in a scanner PTA, the processor is free to effect other jobs whilst TACU instructs an address array TGM to interrogate the peripherals. Data from the latter is gated (G1, G2) into TM2 or TM3 as appropriate while simultaneously PCU retrieves data from TM12 or TM11 in order to update it in dependence on the data that is currently stored in TM3 or TM2 respectively and which PCU reads out by commands on the address wires ao 4-5 and the read-out wires ro 2-4.

Abstract: 1304939 Upholstery BREVETEAM SA 21 April 1970 [25 April 1969] 19006/70 Heading A4M [Also in Divisions B4, F2] An elastic body of foam rubber or foam plastics, with applications as cushions or the like, bedcovers, clothing, sound absorbing covering for walls, heat insulating materials, and pipe wrapping, is provided with two or more series of slits, such as 1, 2, extending through the thickness of the body, each series comprising a plurality of parallel rows of slits, the slits of each series lying in parallel planes which, in the undeformed state of the body, are inclined to the planes containing the slits of the other series and each slit of one series intersecting at least one slit of the other series. In use the body is subjected to traction to open the slits. In one form, Fig. 1, the slits 1 of one series extend at right angles to opposed main faces of the body and the slits 2 of the other series lie in inclined planes. In another form Fig. 2 (not shown) sets of slits (3, 6) lie in planes parallel to respective diagonal planes (5, 8) of a rectangular body. In a further form Fig. 4, (not shown) the slits (9, 10) of the two series extend in mutually perpendicular planes and have respective longitudinal axes (r 9 , r 10 ) extending perpendicular to opposed parallel mainfaces of the body. Other forms Figs. 14-16, (not shown) with differently orientated slits are illustrated. The body may contain fibre tufts, e.g. polypropylene, blown into the body of the material when it is drawn out to an expanded position to open the slits, the fibre tufts being retained in the opened slits when the body is allowed to contract. The cutting of a single series of slits may be effected by compressing the foam body 11 between upper and lower plates 12, 13, Fig. 10, each provided with a plurality of slits 15 and then passing blades 14 through the plate slits 15 and body 11. The body 11 may be rotated before cutting a second series of slits in similar manner. Alternatively, or in addition to rotating the body 11 prior to cutting the slits, the upper plate 12 may be laterally displaced during compression to deform the body 11, as shown in Fig. 13, so that the slits cut in the deformed body 11 will be inclined when the body returns to its undeformed condition. In a further method Figs. 17-20, (not shown) a first series of slits (16) are first cut as previously described, the slit body is then stretched to open these slits and with the body in the stretched condition it is again compressed and a second series of inclined slits (20) is cut.
