Patent GB-1426105-A (GB)
Title: Method of shaping and imparting rigidity to a fabric
IPC: A61F13/04
Filed: 1973-02-02
Abstract: 1426105 Coated fabric D G STOFFEY 2 Feb 1973 [7 Feb 1972 8 Jan 1973 19 Jan 1973] 5244/73 Heading B2E [Also in Divisions A5 and B5] A fabric is shaped to the contours of a non- planar surface and subsequently rigidified by contacting the fabric with the surface, applying to the fabric a thermosetting vinyl monomer or a thermosetting polymerisable unsaturated polymer, the monomer or polymer being activated with a tertiary aromatic amine, the fabric having applied thereto before contact with the surface a free radial catalyst for the polymerisation of the monomer or the further polymerisation of the polymer, and allowing polymerisation to occur while the fabric is in contact with the surface. The polymer may be tihermosetting polyester or acrylic resin or mixtures thereof. The tertiary amine may be N-3 diethanol amine. The catalyst is preferably a peroxide. The polymer may also include a plasticiser. The fabric may be a continuous sheet or a strip and may comprise two or more layers folded on each other as in cotton gauze bandages. The fabric may be woven or non- woven, e.g. an air-laid felt. The fabric may be made of cotton, synthetic fibre or fibreglass. The vinyl monomer or polymer may be applied by spraying, painting, swabbing. The method can be used for producing porous surgical dressings, orthopaedic supports, models, toys, linings, plastics shells, e.g. fibreglass bodies of cars and boats.

Title: An improved process for the production of cuprous oxide rectifier elements
IPC: H01L21/16
Filed: 1937-02-23
Abstract: Cuprous-oxide rectifier elements are made by heating copper elements to incandescence in air from 960-1040 DEG  C., subjecting them to an intermediate treatment lasting for at least 30 minutes at a temperature from 300-600 DEG  C. in a cooling oven and then quenching them in a liquid whose temperature is above 25 DEG  C. but below that of the elements at the end of the intermediate treatment.  The latter may last from 30 to 120 minutes and the upper limit of the quenching liquid may be 100 DEG  C.  Water, melted paraffin or melted wood-metal are suitable quenching liquids.

Title: Device for producing a small flow of vapour
IPC: B01J7/00
Filed: 1947-02-26
Abstract: <PICT:0625765/III/1> An apparatus for producing a closely-controlled flow of vapour, e.g. of ethyl alcohol comprises an electrically-heated vessel having a restricted vapour outlet, wherein the pressure is thermostatically controlled by the rate at which energy is supplied to the heating element.  A metal vessel 1 is closed by cap 4 in which are inserted capillary tube 5 and tube 7 for supplying liquid to the vessel.  The vessel is wound with an electric resistance element 8 divided into three sections, and between these sections are two thermostatic windings 9 of metallic material having a high temperature coefficient.  The thermostatic winding is connected to a bridge circuit, one arm of which is variable so that the temperature at which the bridge may be balanced is variable over a small range.  The output of the bridge is applied either to a sensitive relay or to an amplifier, so that the power applied to the heater-winding can be varied to maintain the temperature of the vessel within close limits.  A heater-winding 10 is applied to tube 5 to prevent condensation of the vapour.  The apparatus is adjusted to maintain the temperature of the vessel a few degrees above the boiling point of the liquid which is to be vaporised.  The heater and thermostat windings may alternatively be inserted beneath the surface of the liquid.  The apparatus may be used to introduce a reagent into a chemical reaction chamber or to introduce a small quantity of odoriferous vapour into a large body of dangerous but odourless gas, so that leakages of the dangerous gas may be detected.

Abstract: 570,827. Cooling and heating plastic &c. materials. STEEL BAND CONVEYOR & ENGINEERING CO., Ltd., and ALLEN, W. H. March 25, 1944, No. 5578. [Classes 29 and 64 (ii)] Plastic or other material carried on a heat conducting endless conveyer band 1 is cooled or heated by liquid in a trough passing around terminal drums on horizontal axes 6 below the band, the underside of which is in direct contact with the surface of the liquid. The liquid may be circulated by a pump through spray pipes 9 and overflow into side troughs 7, and the edges of the band, as also the middle, may be supported by strips 8 mounted on the walls of the trough. For heating purposes the trough liquid may be molten solder kept hot by burners below. The apparatus described is generally similar to that described in Specification 477,488, and may include ducts above the material under treatment for cooling it by air circulation or for removing fumes, &c. during heat treatment. The cooling or heating may be effected in two or more stages, and where the treated material is insoluble and non absorbent, some of the cooling liquid may be sprayed on to the material from above the band.

Abstract: 1413844 Manually-propelled vehicles; manpowered aircraft J WILDE 22 Feb 1973 [8 Feb 1972] 5702/72 Headings B7E and B7G A man-powered vehicle such as a cycle is propelled by arcuate reciprocation of drive levers 11 pivotally mounted at 12 on a frame 10, such reciprocation causing movement of a chain 17 about sprockets 14 and 16 to cause rotation of a wheel 33, as shown, which is attached to the sprocket 14. The sprocket 14 and a sub-frame 15 are pivotally mounted about the same axis on the frame 10, and the sub-frame 15 carries the sprocket 16. A link member 18 is pivotally attached to a drive lever 11 by a pivot 19 and a slide member 30 which may be secured in various positions along the lever 11 by a pin engaging co-operating holes in member 30 and lever 11. The link member 18 is connected to the chain 17 at 20 and carries pins 28, 29 which slidably engage in slots 23, 24 in the sub-frame 15. Instead of the levers 11 extending upwardly from their pivot 12 as shown, they may extend downwardly from a higher pivot point, Fig. 3 (not shown), and in either case the free ends of the levers are provided with handles or pedals. As an alternative to direct drive of wheel 33 by sprocket 14 as shown, Fig. 1, the sprocket 14 may be mounted on a chain wheel (32), Fig. 4 (not shown), which carries a chain driving a further sprocket (34) on the wheel 33. When the invention is applied to a man-powered aircraft, wheel 33 is replaced by the shaft of a propeller or rotor. As shown in Fig. 5, the slide member 30 may be adjustable in position along the lever 11 by rotation of a threaded rod 35 engaged in a threaded aperture 38 of member 30 and mounted on the lever at 36.
