Title: Improvements in weighing instruments for ascertaining the moisture content of wool and other substances
IPC: G01G19/00
Filed: 1926-09-25
Abstract: 266,628. British Research Association for the Woollen & Worsted Industries, Barker, S. G., and Hedges, J. J. Sept. 25, 1926. Computing-apparatus; pendulum-weight apparatus.-A weighing-instrument for use with a textile-conditioning oven for the purpose of ascertaining the percentage of moisture in wool and other substances comprises an arrangement of relatively-adjustable quadrant scales with which is associated an eccentric disc or roller over which is passed a thin metal strip having at its free end a hook adapted to support the material under test. The wool under test is placed in a basket and hung from a hook i attached to a metal strip j. The metal strip is secured to the periphery of an eccentric disc f supported on a steel pivot. A pointer g with an adjusting weight h is carried by the disc and co-operates with a graduated scale a bearing an adjustable scale b. The divisions of the two scales are equal but a division of the scale b represents one hundred times as much as a division of the scale a. The scale b is adjusted and clamped with its zero in coincidence with the pointer. The moisture evaporates under the influence of the conditioning oven until the pointer becomes steady when the percentage of moisture may be calcuated by dividing the reading on the scale b by the reading on the scale a.

Title: Graft copolymers and method of making them
IPC: D06M14/18
Filed: 1963-06-14
Abstract: The dyeability of textile fibres made from C2-C8 monoolefin polymers is improved by grafting them with one or more monomers of the formula <FORM:1032505/C3/1> wherein R is hydrogen or methyl, X is halogen, hydroxy, acrylate, methacrylate or a C1-C4 alkyl radical and n has an average value between 18 and 200.  The grafting may be achieved by means of peroxycatalysts, ozonization of the polyolefin, or under the influence of actinic of high energy radiation.  The monomer may be applied to the textile fibres in undiluted form or in the form of a dispersion or solution.  The examples describe grafting polyethylene glycol 600 methyl ether acrylate from aqueous suspension on to (1) ozonized polypropylene fibres, and (2) polypropylene fibres under the influence of an electron beam.

Filed: 1927-09-15
Abstract: 302,385. India-Rubber, Gutta-Percha, & Telegraph Works Co., Ltd., and Avery, W. L. Sept. 15, 1927. Fluid-pressure; block and shoes acting on drums; disc.-An aircraft landing-wheel brake comprises brake members H thrust into engagement with a drum D<1> or disc by an annular inflatable member G, guiding means preventing circumferential but allowing radial movement of the brake members. The inflatable member is a rubber tube covered with fabric and is contained in a support channel F attached to the wheel axle. The brake members are vulcanized to the tube G and have lateral projections H<1> engaging guide slats in the flanges of the channel F. The guide slats may be inclined as shown in Fig. 7 in order to augment the pressure of the brake members. Each end of the slats may be inclined to augment the brake pressure in both directions. The brake blocks are formed by moulding the friction material round a metal plate having a central hole. The corners of the metal plate are bent over the guiding projections to protect them. The brake blocks may be arranged within a support member and act inwardly on the outer periphery of a brake drum. The brake blocks may be secured by spring return means to the support. The friction material may be secured to the drum. In a disc brake the inflatable member is arranged between a support and a disc which is adapted to be thrust into engagement with another disc.

A contact arrangement for transistors or crystal rectifiers comprises a conducting layer which is evaporated on the surface of the crystal through the spaces in a fine-meshed conducting grid placed on the crystal surface, the layer being insulated from the grid, so as to provide a number of point contacts connected in parallel. The grid may be of copper, and of the type used for electrotypes, with approximately 20 meshes per mm<SP>2</SP>. Fig. 3 shows a rectifier construction, in which a germanium crystal 1 on a base electrode 5, has on its surface, a grid 2 having a thin insulating layer 3. The layer 3 may be provided by evaporating silicon dioxide on to the grid. The conducting layer 4 may be provided by evaporating tungsten by means of electrically heated wires placed close to the grid. The parts of the layer 4 in each of the meshes of the grid provide substantially point contacts on the germanium. The layer of insulation between the grid 3 and the germanium may be omitted, so that the grid contacts the surface,whereby each mesh of the grid co-operates with the contact point of the layer 4 to enable transitor effect to be obtained. Fig. 4 shows a transistor comprising a germanium crystal t, and base electrode 5 in a plastic envelope 6. The grid 2, covered with insulation except for the under surface as described, is held against the crystal surface by plastic ring 7. A tungsten layer 4 is evaporated on to the grid and crystal, and on to contact piece 8. Aperture 12 may be sealed with plastic material.

Filed: 1954-08-27
Abstract: 773,609. Supplying electric fences; charging and discharging condensers. SIEMENS BROS. & CO., Ltd. Nov. 18, 1955 [Aug. 27, 1954], No. 24953/54. Class 38 (4). An arrangement for supply of high-voltage pulses at a slow rate to an electric fence comprises a step-up transformer T, the secondary winding of which is connected to the fence and the primary winding of which is energized from a battery B over a resistor R<SP>2</SP> and contact m<SP>2</SP> of a relay M which is shunted by a large capacity electrolytic condenser C and which is also connected to the battery over a contact M<SP>1</SP> of the relay and a resistor R<SP>1</SP>. Upon closure of a main switch X a charging circuit for condenser C is completed and, simultaneously, flux builds up in the transformer core due to the passage of primary current. When the condenser has charged to a certain voltage, relay M responds and opens its contacts m<SP>1</SP>, m<SP>2</SP>, thereby interrupting both the charging circuit and the flow of primary current. The latter causes the generation of a high voltage pulse in the secondary winding of the transformer, and the former allows the condenser to discharge through relay M which subsequently releases to cause the cycle of operations to repeat. Resistor R<SP>2</SP> and condenser C<SP>1</SP> form a spark-reducing network for the contact m2.
