Title: Improvements in hose pipes
Inventor: CANNEY DUNCAN EDWARD FARMAR
IPC: B29D23/18
Filed: 1960-12-28
Abstract: 934,889. Flexible hoses. GEORGE ANGUS & CO. Ltd. Dec. 22, 1961 [Dec. 28, 1960], No. 44461/60. Class 99(2). A method of making a hose suitable for use both as a suction and as a delivery hose, comprises the steps of placing on a mandrel of lesser diameter than the bore of the hose a helical wire armouring 12 having an initial outer diameter exceeding the bore of the finished hose, drawing over the resulting assembly a textile jacket 10 having a thin lining 11 impervious to fluids, attaching the ends of the jacket to the mandrel, expanding the lined jacket to an internal diameter in excess of the initial diameter of the armouring, freeing the armouring from the mandrel before or after expansion of the lined jacket, shrinking the jacket on to the released armouring, removing the assembly from the mandrel and thereafter applying to the jacket an external helical wire armouring 13 between the convolutions of the inner armouring. The lining may consist of nitril or other synthetic rubber and the jacket may be circularly woven and consist of tensile warps of " Terylene " (Registered Trade Mark) alternating with abrasion resisting warps of cotton, the weft being of nylon or Terylene. The outer coating may be of polyvinyl chloride or of rubber. In making the hose, the inner helix 12 is formed, mounted on a telescopic mandrel 14 and reduced by rotation to a diameter smaller than that of the lined textile jacket 10. The latter is pulled over the mandrel and attached at both ends thereof to the mandrel, the helix being then released to contact the lining 10. Fluid under pressure is introduced into the jacket through a duct 15 in the mandrel to expand the jacket radially to an internal diameter in excess of the initial coiled diameter of the helix, the parts of the mandrel separating to accommodate the increase in length of the jacket caused by the air pressure; this operation permits the helix to return to the original coiled diameter and pitch thereof and the jacket is then deflated to shrink on to the helix and to form corrugations therein. After removal from the mandrel the outer wire helix 13 is wound on to the hose. The release of the helix 12 from the mandrel may be deferred until after the jacket has been expanded. Specification 798,309 is referred to.

The yarn 1 extends across a secant of the cylinder 3. In Fig. 1 the main traverse generating means 6 is a grooved drum. The hollow cylinder 3 is carried by guide means sliding on parallel bars 4, 5; the guide means having a cam member sliding in the groove of the cylinder 6. The cylinder 3 is rotated by compressed air fed through a tube 20. Fig. 7 shows a hollow cylinder 33 in which there is a groove 35 on a chamfer 32 that can be used to lead a yarn into the wavy groove 34. Fig. 9 shows a hollow cylinder that has means 38 for guiding yarn that has jumped out of the wavy groove back into the groove. The slot in the cylinder 3 may define several waves of different or indenitical wave-lengths.

Abstract: 1,189,449. Fuel injection pumps. C.A.V. Ltd. Oct.4, 1967 [Oct.6, 1966], No.44682/66. Heading F1A. In a fuel injection pumping apparatus, a rotary distributer 12 receives fuel from cylinder 13 via a non-return valve 17 and distributes it through a passage 20 which connects in turn with one of the outlets 21 during each pressure stroke of the pistons 14. When the connection is broken the outlet is connected to a leakage path comprising a recess 31, groove 32, a restrictor portion of valve 34 and recess 38 connected to low-pressure. The valve 34 is variably loaded by a spring 35 and in the opposite direction is subjected to feed pump pressure, which is arranged to vary in accordance with speed, acting through restricted passage 50 on the end of the valve, so that the restriction in the leakage path varies according to speed. At rest the valve is held by spring 35 in a position closing the leakage path to ensure maximum fuel on starting.

Abstract: 1,152,876. Measuring humidity electrically. MINISTER OF TECHNOLOGY. Jan.11, 1968 [Oct.11, 1966], No.45383/66. Heading G1N. A hygrometer comprises two semi-conductor diodes D1, D2, in a bridge circuit, one diode D1 being enveloped in an evaporating water surface, so that the bridge output voltage is proportional to the difference between "wet and dry bulb" temperatures. The currents in the arms 3, 4 of the bridge are adjusted and equalized by adjustable resistors RV1, and RV2, a voltmeter being connected in turn at V3, V4 to measure these currents. With both diodes dry, resistor RV4 is adjusted to set the operating point of diode D2 on the most suitable part of its temperature-voltage characteristic, and then resistor RV3 is adjusted to make V1 zero. A wet cotton wick is then supplied to the diode D1. Each diode has its negative terminal extended with tinned copper wire and sheathed in glass fibre, and its positive terminal spot welded to a cupronickel tube which contains the diode just inside one end, this end being then closed with a polished stainless steel sphere containing epoxy resin which fills the space around the diode to improve thermal conductivity. A tubular cotton wick dipping into distilled water is fitted over the sphere containing the diode D1, and both diode assemblies are mounted in a hygrometer head which includes a radiation shield and an aspirating fan. The voltage V1 from the bridge is measured by a long tailed transistor pair, or by a potentiometric recorder, or by a digital voltmeter.

Abstract: 993,516. Measuring pressure electrically. GENERAL ELECTRIC CO. Nov. 19, 1963 [Dec. 19, 1962], No. 45612/63. Heading G1N. A pressure transducer comprises a hollow ferromagnetic toroid 48 whose permeability varies with the pressure of the fluid introduced into it. A second reference toroid 49 is made responsive to atmospheric pressure, and each toroid either carries a transformer winding, Fig. 2 (not shown), the secondaries being connected in opposition, or carries an inductance winding 51, 52 (Fig. 3) the two windings being connected in opposition. An A.C. source supplies the transformers or the chokes. A phase sensitive rectifier 64 provides the meter 69 with a current obtained from the variation in output of the pressurized toroid with respect to the reference toroid. A rheostat 71 (or 31 Fig. 2 not shown) sets the zero of the device, and a thermistor may be included to compensate for ambient temperature variations. The ferromagnetic material used may be an alloy containing nickel and iron, and the fluid inlet tube may be bent into a semi circle along the toroid to absorb any external stresses which would otherwise be applied to the toroid.
