Title: Hoses
IPC: B29C63/06
Filed: 1973-08-23
Abstract: 1439286 Flexible hose IMPERIAL-EASTMAN CORP 23 Aug 1973 [20 Nov 1972] 40073/73 Heading F2P A method of making a flexible hose includes the steps of softening the outer portion of a tubular core 11 formed of a polyurethane resin by subjecting the outer portion to a fluid polyurethane solvent 13, applying a reinforcing layer 12 under tension about the softened outer portion of the core 11, and setting the softened outer portion of the core 11 with at least a portion of the reinforcing layer embedded therein to secure mechanically the reinforcing layer to the core. As described the polyurethane tubular core 11 (Fig. 2) is first passed through a bath of the solvent 13, e.g. tetrahydrofuran, which may be at room temperature or at an elevated temperature and which may have a small percentage of the polyurethane resin dissolved therein. The reinforcing layer 12 is then applied to the softened core 14, the layer 12 consisting of metallic or other fibres, e.g. polyester fibres, and being applied to the core by a braiding machine 15. Alternatively the fibrous reinforcing layer 12 may be helically wound on to the softened core. The solvent is then evaporated at room temperature or by passing the reinforced core 16 through an oven 17. The hose may be provided with an outer sheath of polyurethane by passing the reinforced core through a bath 28 (Fig. 6) containing polyurethane resin dissolved in a solvent, evaporating the solvent in an oven 30 to leave a coating 31 of polyurethane on the reinforcing layer and then extruding an outer sheath 27 on the hose by an extruder 32. In a modification the hose is provided with two reinforcing layers 12, 18 by first wrapping a strip 19 (Fig. 4) around the reinforced core 10, the strip 19 of polyurethane having been passed through a bath of solvent 20 to soften it, then applying a second reinforcing layer 18 by a braiding machine 24 and then evaporating the solvent by an oven 25. An outer sheath is then applied as described above to provide the finished hose.

Title: Improvements in or relating to knitting machines
IPC: D04B15/88
Filed: 1963-10-15
Abstract: 993,959. Knitting-machines. SCOTT & WILLIAMS Inc. Oct. 15,1963 [Feb. 7, 1963], No. 40735/63. Heading D1C. Fabric take-down mechanism for a circular machine is of the cup and cap type 90, 60 operated pneumatically so that it is raised to receive the welt of a stocking as it is produced after which it is released to clamp the welt and exert a pull on the fabric as it is produced on the machine. The machine has an inner cylindrical tube 22 supported within the needle cylinder within which the take-down mechanism slides. The cup and cap are supported on bearings 88, 66 carried by a rod 72 supporting at its lower end a piston 74 capable of sliding up the outside of the cup which it does when after the mechanism has been pneumatically raised by air under pressure being introduced beneath the piston the cup engages a stop 96 at the upper end of the cylinder. Continued upward movement of the cylinder causes the piston to slide over the cap and simultaneously to raise the cap 60 away from the upper edge of the cup with the result that a coil spring 84 between the cup and piston is compressed. The welt of the stocking having been commenced it is urged downwardly into the cup by air under pressure directed through a tube 98. The air from this supply passes through openings 94 in the wall of the cup and through openings 44 in the wall of the inner cylinder 22 to atmosphere without influencing the piston 74 which is retained in a raised position by the pressure of air beneath it. On completion of the welt the air supply beneath the piston is stopped and the cap closed on the welt to clamp it in the cup under the influence of spring 84 whereafter the cup and cap tension the fabric as it is produced by dropping under the influence of gravity. On completion of the stocking the fabric is cast off the needles and the mechanism drops to the bottom of the inner cylinder 22. An apertured sleeve 50 is then rotated to align its apertures 52, 30 with the aperture 36 in the cylinder and a nozzle 61 respectively. Simultaneously a catch 118 engages the cup 90 and prevents it upward movement when the piston is made to rise under air pressure to cause the cap to rise and release the fabric, an air blast from the nozzle 61 causing the stocking to be ejected through the apertures 36 52. The mechanism is then ready for the further take-down operation of the next stocking. Reference has been directed by the Comptroller to Specification 800,435.

Title: Improvements in self-regulating reciprocating action pumps, and in particular in fuel injection pumps
IPC: F02M59/32
Filed: 1958-12-18
Abstract: 895,857. Fuel injection pumps. BESSIERE, P. E. Dec. 18, 1958 [Dec. 18, 1957], No. 40931/58. Class 102(1). A fuel injection pump comprises a main piston 1 driven at a speed proportional to the engine, which hydraulic actuates a " shuttle " piston, which as shown is in the form of two interconnected piston members 5, 11, to deliver fuel through an outlet 13, a by-pass 8 determining the end of the discharge stroke. The " shuttle " piston is loaded by a spring 6 while a chamber 12b on the underside of the portion 11 is fed with liquid, distinct from that delivered by the pump, by a gear pump 22 driven at a speed proportional to the engine. The return stroke of the " shuttle " piston under the action of the spring is braked by the outflow of liquid from the chamber 12b past a throttle 20 which may also be adjustable manually or in accordance with engine speed. A by-pass 23 from the gear pump is controlled by an adjustably loaded relief valve 24 which may be locked in the closed position. When the speed of the engine exceeds a predetermined value, the return stroke of the " shuttle " piston is not completed before it is again actuated by the main piston thus reducing the stroke of the " shuttle " piston and hence the quantity of fuel delivered. As shown the liquid delivered from chamber 12a may be that used to actuate the " shuttle " piston, this being transferred from a chamber 4 below the piston portion 5 to the chamber 12a via conduit 28 which conduit is closed by a valve 29 during the delivery stroke. Alternatively the chamber 12a may be fed directly by a fuel supply pump (not shown). In a modification, the " shuttle " piston is formed as a single piston member connected by a lever to a second piston movable in a separate cylinder. This second cylinder is fed, on one side of the piston, with liquid from a gear pump in the same manner as chamber 12b and the second piston controls the return stroke of the " shuttle " psiton in the same manner as the piston portion 11. Specifications 861,754 and 885,297 are referred to.

Title: Emergency oil supply for a bearing of a decelerating shaft
IPC: F16N29/00
Filed: 1963-10-28
Abstract: 979,157. Lubricating. GENERAL ELECTRIC CO. Oct. 28, 1963 [Nov. 20, 1962], No. 42361/63. Heading F2A. A lubrication system for a bearing of a rotating shaft which decelerates according to a known schedule, comprises means to supply oil to the bearing during normal operation and emergency means supplying oil to the bearing when the normal oil supply is interrupted; the emergency oil flows rate being controlled by regulating means which maintains the flow at rates varying during the deceleration process in accordance with a flow schedule derived from the shaft deceleration schedule, which determines the amount of flow necessary throughout the deceleration process to limit the maximum bearing temperature to a predetermined value. In an embodiment, a shaft 2, Fig. 1, is mounted in a bearing 1 which is supplied with pressurized lubricant through a pipe 3, having a restrictor 4 and a non-return valve 5 therein. The bearing 1 is connected to emergency oil supply tanks 7, 8 by pipes 12, 13, the former of which leads into the pipe 3 and the latter having a restrictor 14 therein. On failure of the pressurized lubricant a trip device 6, which is connected to the pipe 3, emits signals and stops the shaft 2 from rotating, whereupon the lubricant is fed to the bearing from the tanks 7, 8. Due to the restrictors 4, 14 and the respective sizes of the tanks, the rate of flow of the lubricant gradually diminishes as the shaft decelerates, the temperature of the bearing remaining substantially constant. When the pressurized lubricant is again available, the tanks 7, 8 are refilled through their bases, the filling being facilitated by a connecting-pipe 9 and a vent-pipe 11 and a non-return valve 10 being provided in the pipe 11. In modifications, the tanks 7, 8 are replaced by a small tank 20, Fig. 3, having pressurized gas forcing lubricant through fixed and adjustable orifices when emergency lubricant is required, float-operated valves being provided for the pressurized gas and for the adjustable orifice; a single tank 30, Fig. 4, has a baffle 33 which divides the lower half into separate chambers and may have holes 33a therein; and tanks 7<SP>1</SP>, 8<SP>1</SP>, Fig. 5, would provide an accurate rate of flow should this be necessary.
