Title: Backing fabric
Inventor: BAGULEY MAURICE EDWARD
IPC: D04H13/00
Filed: 1964-03-17
Abstract: 1,092,942. Laminates. COURTAULDS Ltd. March 16, 1965 [March 17, 1964], No. 11148/64. Heading B5N. A laminated fibrous material comprises a bonded layer of fibres in which a major proportion of the fibres are substantially parallel to the surfaces of the layer, a carded web of fibres, and between them, a reinforcing fabric, the layers being consolidated by needling. Specified fibres for the bonded layer are polyamide or polyester fibres bonded by chemical or physical means. The reinforcing fabric may be woven or knitted, preferably of open construction, e.g. a scrim, and is preferably produced from polyamide fibres. The carded web may be produced from natural or synthetic fibres, e.g. polyester, polyvinyl chloride, polyacrylonitrile or polyamide fibres (which may be crimped). Two carded webs may be used. The consolidated laminate may be impregnated with an aqueous emulsion of a copolyamide and a modified ethyl acrylate polymer, the polymers being gelled with dilute hydrochloric acid and hardened by dilute aqueous ammonia to produce a microporous structure.

Title: Process for making fillings, crowns and prostheses for dental purposes
IPC: A61K6/891
Filed: 1958-04-09
Abstract: Dental fillings, crowns and prostheses are made from a mixture of an epoxy resin and a hardening agent, the latter being either a stable complex of a Friedel-Craft's catalyst or boron trifluoride with an organic compound.  Suitable catalysts are stannic chloride, antimony pentachloride, zinc chloride and boron tri-fluoride and, if desired, these may be dissolved in a suitable solvent, preferably one which reacts with the resin to take part in the hardening action, such as alcohol.  Polyglycidal ethers or esters are suitable resins but mixtures may be used.  For convenience in use the catalyst may be stored as a liquid or as a paste, in the latter case, by being mixed with finely dispersed silica.ALSO:Dental fillings, crowns and prostheses are made from a mixture of an epoxy resin and a hardening agent, the latter being either a stable complex of a Friedel-Craft's catalyst or boron trifluoride with an organic compound.

Abstract: 717,275. Hand-actuating devices for switches. GENERAL ELECTRIC CO., Ltd., BRANDRETH, R. D., and GARTHWAITE, F. N. May 5, 1953 [May 5, 1952], No. 11303/52. Class 38(5) [Also in Group XL(c)] . A switch assembly, especially for a radio receiver, comprises two rotary three-position switches 2, 3 having their spindles 4, 5 perpendicular to a common operating member 1. Spindle 4 has an arm 7 with a recess engaging a pin 9 on member 1, and spindle 5 has an arm 10 carrying a pin 11  passing through a slot 12 in member 1. As shown, both of the switches are in their central positions and if member 1 is moved to the left or right, the arm 7 and spindle 4 are rotated to operate switch 2. During this movement, pin 11 is in a straight central part of slot 12 so that switch 3 is not operated. However, if member 1 is now moved further in the same direction, an inclined part 13 or 14 of slot 12 will engage the pin 11 and actuate switch 3, the member 7 disengaging from pin 9 during the further'movement so that switch 2 is unaffected. Switch 2 may have a central " off " position and may connect the receiver to the mains or a battery in its other positions. Similarly, switch 3 may act as a wavechange switch giving the medium-wave in its central position and the long wave in its outer positions. Each switch may have a locating device.

Filed: 1920-04-28
Abstract: 166,738. Hill, F. April 28, 1920. Safety appliances. - A safety-guard for tramcars and like vehicles comprises a pivoted tray-like frame a, Fig. 1, normally supported in a substantially horizontal position by means of a toggle mechanism l, m and adapted to be swung down to its operative position b y means of a weighted lever f, Fig. 3, which is actuated either by a pivoted gate v at the front of the vehicle being struck or by the momentum of the weight itself when the motion of the vehicle is quickly retarded, for example, by the application of the brakes. The tray or guard a is attached to a rotatable shaft c which is supported by rods from the frame d and is rigidly attached to the weighted lever f and also to the lower arm m of the toggle mechanism. The upper arm l of the toggle-lever has a a sliding connection with the lower arm k<1> of a lever k pivoted at i, Figs. 3 and 4, to a fixed bracket h, the upper arm k<2> being connected by a link p to a pedal q<1> controlled by the driver. Situated immediately behind the hinge m<1> of the toggle is a lever t pivoted at a to the bracket h and connected by a link u to the gate v. Normally the toggle hinge m<1> lies to the rear of the vertical plane through the shaft c and pivot i, but is moved forwardly in front of this plane either by the lever t when the gate v is struck, such movement also causing the shaft c to turn throwing forward the weight g and depressing the tray a, or by the momentum of the weight g alone when the brakes are applied. A spring s located between shoulders on the arms k, l assists in holding the toggle in either of its positions. Resetting of the tray is effected by depressing the pedal q<1> so as to move the toggle hinge backwards and elevate the tray a and weight g. The tray a preferably has a front portion formed of flexible chains and has a rear guard wand side shields y.

Classes 7(2) and 7(6) In a two-stroke reciprocating engine comprising chambers 9, 19 and 1a in the engine frame 2 for scavenging air, supercharging air or mixture, and exhaust gases respectively, the reciprocating cylinder 4 is provided with a first group of ports 10 co-operating with the chambers 9, 19, to control the admission of scavenging air and supercharging air or mixture and a second group of ports 6 controlling the escape of exhaust gases into the chamber 1a. The cylinder 4 is reciprocated by eccentrics 12 leading the pistonoperating crank 16 by an angle a, so that on' the upstroke the ports 10 first admit the low-pressure scavenging air from the chamber 9 and then open the ports 21 to admit high pressure supercharging air or mixture, and on the downstroke the piston 3 blocks the ports 10 to prevent the entry of supercharging air. The cylinder 4 may be provided with a separate ring of ports above the ports 10 for the supercharging air or mixture. Reference has been directed by the Comptroller to Specification 715,497.

In the hot extrusion of metals which are difficult to extrude, such as high-speed tool steels on silicon bronze, there is interposed between the billet and the extrusion die an auxiliary disc of a metal which at the extrusion temperature is more readily deformable than the billet metal. For high-speed tool steel billets, the disc is of low or medium carbon steel; for molybdenum billets the disc is of 0.1 per cent carbon steel; for silicon-bronze billets the disc is of commercial bronze. This disc may be attached to the billet, e.g. by welding, and will thus be heated to the same temperature as the billet. Alternatively the disc may be inserted in the billet container before the billet and may be heated independently thereof and to a different temperature. The disc forms a front portion 4a on the extruded bar 5 which portion is of much shorter length than the faulty.portion of a bar extruded without the auxiliary disc; this portion 4a is cut off. A glass lubricant is also used and may be in the form of glass wool or may be of heat-resisting glass. Specification 607,285 is referred to.
