Title: Automatic vulcaniser and heating composition for vulcanising
IPC: B29C35/00
Filed: 1930-09-27
Abstract: 360,586. Vulcanizers. OFFICE GENERAL DES SP•CIALIT•S AUTOMOBILES, 47, Rue Veuve-Lacroix, La Garenne-Colombes, Seine, France. Sept. 27, 1930, No. 29005. Convention date, Sept. 30, 1929. [Class 70.] A combustible composition for supplying heat for vulcanizing, consists of a mixture of trioxymethylene and a solution of colophony in ethyl alcohol, or of gum arabic or fish glue in water. Suitable proportions are 175 parts of trioxymethylene to 100 parts of a solution of 90 gm. of colophony in a litre of alcohol, or of 50 gm. of gum arabic or fish glue in a litre of water. The composition is ignited by a pellet containing 25 gm. of charcoal, 20 gm. of potassium chlorate, and 100 gm. of the solution of colophony in alcohol. A press for vulcanizing, e.g. patches to tyre tubes consists of a stirrup 1 having a bottom plate 2 with an interchangeable bulged plate 7 thereon, on which the tube is placed, and a metal pan 3 having a patch 4 on its lower surface, and containing the composition 5, and a pellet 6 of the igniting composition. The pan is clamped on the work by a sliding rod 9 carrying at its lower end a cross piece 10 and operated by a lever 11 with toothed segment 13 engaging a rack 14 on the rod 9. A series of teeth 15 on the stirrup 1 engaging a projection on the lever handle serves for locking the latter. When clamped, a spark is projected on to the igniter by depressing a button 17 which causes a roughened rod to rub on a ferrocerium stone held by a screw 24. Modified levers and clamping means are described, including one in which the lever bears directly on the head of the rod 9. The ends of the cross piece 10 are protected from accidental touching of the tube by an insulating lagging. Too rapid burning of the composition is prevented by a ring mounted on the cross piece, and covering part of the pan.

Title: Triazine derivatives
Inventor: FORBES ALAN DAVID
Filed: 1964-06-15
Abstract: The invention comprises compounds of the formula <FORM:1107987/C2/1> wherein R is an alkyl, alkoxy or fluoroalkoxy group having 1-3 carbon atoms, and R1 are phenoxy or cresoxy groups.  The compounds are prepared by reacting a triazine compound of the formula <FORM:1107987/C2/2> in which Y is a halogen atom, with a compound R1-X, where X is an alkali metal.  It is preferred to effect the reaction at 15-25 DEG  C. in an inert solvent using stoichiometric proportions of the reactants.  Examples relate to the preparation of 2-methyl-4,6-diphenoxy-1,3,5-triazine, 2,4 - di - o - cresoxy - 6 - ethyl - 1,3,5 - triazine, 2 - ethoxy - 4,6 - diphenoxy - 1,3,5 - triazine and 2,4 - di - o - cresoxy - 6 - (1,1,3 - trihydrotetrafluoropropoxy)-1,3,5-triazine.

Title: Irrigation conduit and method for producing such

Filed: 1968-06-19
Abstract: 1,237,097. Extruded irrigation pipe. F. BUTRUILLE. 19 June, 1968 [22 June, 1967], No. 29138/68. Heading B5A. [Also in Divisions C3 and F2] An irrigation, or soaking, conduit 5 has a wall structure of intercommunicative cellular plastics material, e.g. formed ethylene polymers and copolymers, and an outer surface which, at normal operative pressures, is impervious to water, the wall having at least one score line 9 which penetrates the outer surface and destroys its water impervious nature. As shown, the conduit has four longitudinal score lines 9. Alternatively, a single helical score line, or a number of axially-spaced, ring-shaped, score lines, may be provided. The conduit is formed by extruding a hot hollow conduit from a foamable thermoplastic resin, e.g. polyethylene, with an alkali metal bicarbonate gas-releasing agent and a small amount of naphthylenic-type pail oil, the extruding taking place at about 300- 360 F. Air is then forced through the extruded conduit to expand it as it passes through the extrusion die and into a cooled sizer which cools, sizes, and hardens the conduit to form a water impervious external wall surface. The air injection also aids in connecting the cells of the foamed plastics. Each score line is then made in the external wall surface.

Abstract: 659,098. Stud and - socket. fastenings. FERNBERG, E. B., and FERNTOL PATENTS Ltd. Nov. 10, 1948, Nos. 29263 and 32637. [Class 44] [Also in Group X] In a snap fastener for attaching trim panels and the like to an automobile body, comprising a stud 10, Fig. 1, formed from a spring metal strip bent to U or diamond shape, and formed with a waist 15 and a pair of outwardly directed feet 16, 17, a U-shaped strip metal retainer is apertured in one of its flanges to encircle the waist 15 of the stud, the stud being substantially at right angles to the retainer. The stud is inserted in the aperture 25 which is provided in one flange 21 of the retainer, by pinching the feet 16, 17, together and passing the waist 15 through an entering slot 26. An edge of the trim panel is then inserted between the flanges 18, 21, of the retainer and maintained therein by prongs 19, 20, on the flange 18. The upper flange 21 is bent inwardly at 22 and outwardly at 23 to leave a channel 24 the feet 16, 17, thereby being enabled to move when inserting the stud 10 in an aperture in a vehicle panel. Prongs may be provided on both flanges and the latter may have strengthening ribs 27, 28. In a modification, Fig. 3, in which one foot 38 is longer than the other 37, the feet are inserted in an aperture 42 in one flange 40 of the retainer. This flange is wider and longer than the other flange 41 and is internally ridged at 43 to allow the upper surface of the flange to stand away from the trim panel and leave room for the feet 37. 38, to move. In either embodiment the edges of the upper flange 40, or 21, may be bent to L-section, or their extreme ends may be offset downwardly to space the upper flange from the trim-pad. In an alternative embodiment described in the first Provisional Specification, a slot leading to aperture 42 may be provided and two ridges 43 may be formed in the upper flange. Specification 451,721 is referred to.

Abstract: 1427073 Automatic control SOC D'ETUDES RECHERCHES ET CONSTRUCTIONS ELECTRONIQUES 22 June 1973 [17 Aug 1972] 29810/73 Heading G3N An apparatus for point-to-point positioning of a movable assembly comprises a linear position detector providing electrical information to a logic circuit controlling a general control motor, for initial movement mechanicially coupled to a stepmotor for final positioning. As shown, a positioning arrangement for a wiring machine comprises a control block 10 receiving from a perforated tape-reader, (not shown), desired position signals which are used to select, by a circuit 8, conducting strips of a contactposition system 6, 7 having a roller 6 fastened to a machine element 5. The desired position signal is also fed together with an actual position signal from system 6, 7 to a comparator 11 from which forward and reverse signals DIR; INV are desired for control of an electric motor 1 through a circuit 20. In the event of the element being at the desired position a signal EGA initiates a wiring operation. The circuit 20 also receives a signal ITER from a shaping circuit 9 which is indicative of the element 5 reaching the desired position. The motor 1 is controlled by signals Gl, G2 in dependence on the required direction and on receipt of the signal ITER is energized in the reverse direction. The motor 1 is de-energized, after a delay, on receipt of a signal ART signifying zero-speed. The signals G1, G2 are used to determine the direction of rotation of a stepping motor 2 used to finally position the element 5. The stepping motor 2 is controlled by a circuit 20 and during positioning by the motor 1 operates as a polyphase alternator providing signals whereby the signal ART is derived. The motor 2 is stepped until receipt of a second signal ITER, indicating that the element has returned to the desired position. In a modification the stepping motor is responsive to supplementary pulses determined by signals from the tape-reader.
