Title: Textilereinforced all-polymeric hose and method of making same
IPC: B29D23/00
Filed: 1970-10-16
Abstract: 1324420 Plastics tubes UNIROYAL Inc 16 Oct 1970 [17 July 1970] 49318/70 Addition to 1302964 Heading F2P A reinforced hose 1 is made by helically winding a layer of parallel thermoplastics textile reinforcing elements 3 around a thermoplastics tube 2 at an angle to the tube longitudinal axis and fusing the reinforcing layer to the tube; helically winding another such reinforcing layer 5 around the first layer in the other direction at the same angle to the tube longitudinal axis and fusing the second layer to the first layer; and encasing and bonding the tube and layers in a protective thermosetting polymeric jacket 7. The tube 2 is passed through a bath of plasticizing agent at elevated temperature to soften the outer surface and is then passed through a wrapping machine which applies the first reinforcing layer 3, the plasticizing agent still acting on the tube and the layer 3 to promote fusing at the contact surfaces. The fused tube 2 and layer 3 are then passed through a water bath to remove the plasticizing agent, and then through an oven, microwave unit, or infra-red unit, to remove the water. The plasticizing-wrapping-washing-drying operation is repeated for the application of layer 5. The fused tube 2 and layers 3, 5 is passed through a plasticizing agent bath and then the agent is removed by the passage through a water bath before the application of the protective jacket 7 by an extruder, which forces the jacket material into nearly all the interstices between the elements of the reinforcing layers 3, 5 and is subsequently vulcanized. The resulting hose 1 is then cooled. The reinforcing elements consist of multifilament yarns comprising continuous or discontinuous synthetic filaments, or consist of solid single component elements of cylindrical cross-section or a tape of spaced textile elements held together by a light weft. Thermoplastics materials used for the tube and reinforcing layers are nylon 6, nylon 66, a copolymer of both, polyesters, vinyl plastics, acrylic plastics, vinylidene chloride polymers and copolymers, polyolefins, polyurethanes, butadiene-styrene copolymers; the hose 1 may be of any one or more of these materials. Thermosetting materials are:- curable polyurethanes, curable elastomers, e.g. natural rubber, neoprene, nitrile rubber, SBR, CBR, IR, EBR and EPDM, curable resin-rubber blends. The plasticizing agent for nylon is:- resorcinol - water solution, resorcinol - ethanol solution, fluorinated ketones, e.g. hexafluoroacetone as a gas or aqueous solution or in liquid hydrate form. For polyesters, the agent is:- hot meta-cresol in water, cold aqueous solution of ortho-chlorophenol. For removing the plasticizing agent, besides a water bath, a cascade of washing medium into the assembly can be used, of:-water, ethanol, or aqueous ethanol.

Abstract: 1,039,199. Data transmission. SIEMENS & HALSKE A.G. Dec. 8, 1964 [Dec. 9, 1963], No. 49835/64. Heading H4P. In an error-correcting data transmission system the data is transmitted at high speed and, in response to a repetition requesting signal from the receiver, repeated data is transmitted at low speed on another channel. In the embodiment described data from a magnetic or punched tape transmitter is converted to errordetecting code or has parity bits added and is transmitted over a wide-band channel to the rereceiver where it is printed unless an error is detected, in which case a repetition-requesting signal is returned, indicating the signals in error. A second transmitter recieves the tape from the first transmitter and transmits the incorrectly received data twice, in the same or inverse form, at low speed over a narrow-band channel. At the receiver the repeated data is checked and, if correct, is printed in the space on the tape resulting from the initial detection of error.

Abstract: 1401500 Treating exhaust gases NISSAN MOTOR CO LTD 7 Nov 1972 [10 Dec 1971] 51357/72 Headings B1L and B1W [Also in Division F1] Toxic compounds in exhaust gases from an I.C. engine having an induction passage 16 and an exhaust manifold 20 are reduced by having a first branch conduit 26 connected from the induction passage to a pump 28 to supply air to a denitrogenating unit 42, which supplies denitrogenated air via conduit 50 to the exhaust manifold 20 and nitrogen via a pump 60 to induction passage 16. The denitrogenating unit comprises at least two nitrogen separating means 44, 46 connected to two-way valves 40, 48 so that when one of the means 44, 46 is absorbing nitrogen to produce denitrogenated air for the exhaust manifold, the other is having its absorbed nitrogen sucked out by pump 60 via conduits 54, 56 and fed to the induction passage 16. For example, when means 44 is denitrogenating air, valve 40 connects conduit 32 to inlet 44a and conduit 54 to inlet 46a and valve 48 connects outlet 44b to conduit 50 and outlet 46b to conduit 56. The two way valves 40, 48 and shut off valves 34, 52, 58 and 36 are controlled by unit 64 in response to engine speed, intake manifold vacuum and engine coolant temperature. Valves 34 and 52 are open whenever the engine is operating and valve 58 is open during normal running, but closed during starting and deceleration. All three are closed when the engine is inoperative to prevent the ingress of moisture etc to the nitrogen separating means. Valve 36 can be opened to supply additional air to the exhaust manifold. The means for separating nitrogen from air (Fig 2) includes dehumidifying layers 80, 82 of silica gel and CO 2  absorbent layer 84 of zeolite. The nitrogen absorbent layer 86 comprises a nitrogen impermeable membrane and a molecular sieve of zeolite processed from natural zeolite.
