Title: A method of coating articles of cellular rubber with a plastic, and articles so produced
Filed: 1954-07-27
Abstract: A plastisol comprises polyvinyl chlorides of two different melting-points, dioctyl phthalate, a plasticiser of the polymeric polyester type, the dibasic lead salt of phosphorous acid, and a pigment consisting of calcium carbonate and titanium dioxide. Specifications 500,298, 725,100, [Group V], and U.S.A. Specification 2,629,678 are referred to.ALSO:A body of cured cellular rubber is provided with an adherent coating of a plastisol by applying the latter to all or part of its surface, and then "fusing" the plastisol by heat, the term "fusing" having the same meaning as in Specification 725,100 [Group V].  The plastisol acts as a heat insulation for the cellular rubber, any uncoated portions of which must be protected with such material as wood, porcelain, cellular glass, or asbestos-containing or other fibre board.  The bottom and side walls of an open mould may be coated with a plastisol, in which the body of cellular rubber is placed, and its upper surface coated with plastisol, so that it is entirely enclosed therein; the whole is then subjected to an atmosphere of gas, e.g. air, at 300 DEG F. to 450 DEG F., for a period sufficient to fuse the plastisol. A weight may be applied to the upper plastisol-coated portion to keep the cellular rubber body submerged.  The plastisol coating the sides and bottom of the mould may be heated sufficiently to gel, but not fuse it, before insertion of the cellular rubber body, in which case the pre-gelled portions do not adhere thereto. Examples of polyvinyl chloride plastisols are given.  The cellular rubber may be either of sponge or closed-cell type, and may be of natural rubber, GR-S, "Buna N" (Registered Trade Mark), a rubbery copolymer of a major proportion of isobutylene and a minor proportion of aliphatic conjugated diolefine (butyl rubber) or neoprene.  The invention may be applied to round, rectangular and channelled foam or sponge rubber, sheets, cushions, armrests, locker sandal platforms or underwater swim suits. Specification 500,298 [Group IV] and U.S.A. Specification 2,629,678 also are referred to.

An internal chimney 1 for a lamp burning vaporized fuel comprises a cylindrical member and an external annular flange formed integrally with one another by a deep drawing process and one or more openings 5 formed at the end of the cylindrical member remote from the flange. The openings are formed by cutting the top of the chimney in such manner that two parts 6 can be bent upwardly from a middle part 7, the parts 6, 7 forming a bridge integral with the chimney. The middle part 7 has two holes for the passage of the two legs of a mixer tube 11 and the parts 6 have vertical slots 8 through which pass screws 9 for adjustably securing the inlet end of the mixing tube in spaced relation to a jet 14 on the end of a vaporizing tube 13. The inlet end of the mixing tube and the jet 14 are located in an air chamber 12 fixed to the interior of the chimney at a lateral aperture therein. The leg of the mixing tube supporting the mantle 20 is supported by a distance piece 17 from the air chamber. The mixer tube can be throttled by means of a screw 21.' The chimney rests on a carrier ring 2 and a hood 3 with air apertures rests on the upper edge 4 of the chimney, an annular space being formed between the chimney and the hood.

Abstract: 1308647 Digital calculating MESSERSCHMITT-BOLKOW-BLOHM GmbH 6 May 1970 [9 May 1969] 21940/70 Heading G4A In apparatus for measuring the true northerly speed of a body (e.g. fighter aircraft) in air, northerly component of speed signals are obtained from a Doppler measuring device and an inertial speed measuring device, using an apparent northerly direction indicated by the inertial device, and are continually compared, the apparent northerly direction being adjusted in accordance with the comparison result until the northerly component of speed signals agree. Before comparison, the speed signals are weighted according to the northerly and easterly acceleration and position about the rolling and pitching axes, as indicated by the inertial device, to give the inertial signal preference at high accelerations and at extreme flight positions when the angle of incidence of the radar ray from the Doppler device on the Earth is excessively acute (in the latter case, the Doppler device may be shut off completely). If the difference signal from the comparator is non-zero, a new north direction is calculated iteratively using characteristic error equations for the two devices and used to correct the speed component signals. The difference signal is also stored and compared in a second comparator with the next difference signal and if the latter is larger, the calculated north direction has an incorrect sense relative to the apparent northerly direction and this sense is changed. The Doppler speed and the corrected north are displayed, and an acoustic or optical signal is given when the comparision of speed component signals gives equality. Before takeoff of the aircraft, the inertial device is aligned approximately north using a geomagnetic field pick-up, and approximately horizontalized. The aircraft position can be calculated in known manner from speed signals.

Aug. 3, 1935, No. 22062. [Class 83 (iii)] In screw-thread cutting devices wherein the die or tap-holder is rotated in the same direction as the work but at a greater speed for cutting, and is stopped for unscrewing, a detachable toolhead 14, Fig. 2, is provided comprising a constantly rotating driving member 12 provided with a clutch face or dogs 20, Fig. 3, a revoluble and longitudinally movable driven member 22 having dogs to engage the driving member, and under the action of a spring 28, the driven member being further provided with a clutch face 29 engaging a similar face on the fixed body part 30 which retards its rotation when moved to the left out of engagement with the driving member and serves to withdraw the screwing tool 25. Towards the end of a screw-thread cutting operation the longitudinal motion of the turret carrying the device is arrested, but the forward pull of the work on the tool continues and disengages the driving and driven members, moving the latter against the brake surface 30. A ring-shaped cam-member 32 which is thereby released is urged around by a peripheral spring 38 to force the driven member against the brake surface. The cam member is automatically re-set on retracting the turret by a stop 43 which engages a lever 45 projecting from the screw-cutting device.

[Also in Division B8] A bottle cap (see Division B8) having a lid and a separate skirt is made from a cup-shaped blank C of metal or alloy. In a first step, a tool A, Fig. 3, forms two semicircular slots T adjacent the side 2 of the blank C, to define the lid 1 of the cap. The lid 1 remains connected to the side 2 of the blank only by two bridge portions (S), Fig. 6 (not shown), between the slots T. In a second step, the blank C is removed to a second tool B, Fig. 4, which breaks the bridge portions (S) to separate the lid 1 from the side 2 of the blank, bends over the top lip 7 of the blank side, and reduces the diameter of the upper part 302 of the blank side, thus forming an annular shoulder 202. In a third step, the half-formed cap is now removed to a third tool D, Fig. 5, which rolls-in the lower lip 5 of the cap skirt 102 and simultaneously imparts a conical taper to the reduced diameter upper part 302 of the cap skirt, so that the cap lid 1 is retained between the top lip 7 and the annular shoulder 202.
