Title: Method of treating rubber-reinforcing fibrous material for improving heat resistance thereof
IPC: B29D30/40
Filed: 1961-07-19
Abstract: A composition suitable for treating fibrous materials used for reinforcing rubber products comprises a vegetable oil, preferably a drying oil or semi-drying oil, and a diallyl tin carboxylate, e.g. di-n-octyl tin bis-monobutyl maleate, dibutyl tin distearate, dibutyl tin dilaurate and dibutyl tin dimaleate, or a tri-organic tin sulphide, e.g. a trialkyl tin sulphide having the formula (R)3 Sn-S-Sn(R)3 in which R is an alkyl group such as bistrilauryl tin sulphide. The vegetable oil may be soybean oil or cottonseed oil. The composition may be diluted with water or an organic solvent, e.g. a mixed solvent of CCl4 and CH3OH in the ratio of 3 to 1, and applied to the fibrous materials at the spinning stage or after spinning. When diluted with water the mixture may be emulsified with an alkyl ether or ester of polyethylene oxide.ALSO:Fibrous materials, e.g. viscose rayon and nylon cords and duck, which are to be used for reinforcing rubber products, e.g. tires and conveyor belts, are treated with a dialkyl tin carboxylate or triorganic tin sulphide to improve their heat and fatigue resistances and the strength of the adhesive bond formed between the fibrous material and the rubber. The organic tin compound may be di-n-octyl tin bis-monobutyl maleate, dibutyl tin distearate, dibutyl tin dilaurate or dibutyl tin dimaleate or a trialkyl tin sulphide having the formula (R)3 Sn-S-Sn(R)3 in which R is an alkyl group, e.g. bistrilauryl tin sulphide.  The organic tin compound or a mixture of vegetable oils mainly consisting of fatty acid glycerides with the organic tin compound may be diluted with water or an organic solvent e.g. a mixed solvent of CC14 and CH3OH in the ratio of 3 to 1, to form a treating composition containing not more than 10% by weight of the organic tin compound and applied to the fibrous materials so that the pick-up on the fibrous material is 5% by weight or less.  When diluted with water the mixture may be emulsified with an alkyl ether or ester of polyethylene oxide. After treatment with the organic tin compound the fibrous materials may be dried at 50 DEG -160 DEG C. and then treated with a resorcinformaldehyde latex adhesive and incorporated in the rubber.  The organic tin compound may be applied to the fibrous material at the spinning stage or after spinning or may be incorporated in a resorcin-formaldehyde latex used to treat the fibrous material before incorporation into the rubber.

Title: Process for the production of flexible elastic sheets
IPC: D06N3/00
Filed: 1952-10-22
Abstract: 717,103. Coated knitted fabrics, compound fabrics. METALLGES, AKT.-GES. Oct. 22, 1952 [Oct. 29, 1951; Dec. 24, 1951; March 8, 1952], No. 26563/52. Class 140. Flexible elastic sheets are produced by coating or impregnating a wide-mesh knitted fabric, e.g. polyamide or cotton, with a coagulating agent, dipping the coated or impregnated fabric in a stretched condition into a dispersion of an elastomer, removing the fabric from the dispersion, drying the partially or completely coagulated layer covering the meshes of the fabric, and, if desired, vulcanizing. Alternatively, one or more compressed air currents are directed onto a part or the whole of the dipped fabric, before drying, to disrupt some or all of the liquid lamellµ between the meshes to form perforated sheets. The air currents may be periodically interrupted to form discontinuous perforation patterns. Fibre dust may be adhered to one or both sides of the dipped fabric before drying. The elastomer may be natural rubber, gutta percha, balata, or synthetic rubbers such as polychloroprene, or mixed polymers of butadiene with styrene or acrylonitrile. A fabric stretchable in at least one direction, preferably a knitted fabric having a porous elastic coating obtained by spraying with latex containing vulcanizing agents or prevulcanized, so that a continuous layer is not formed, may be applied with the coated side towards the sheet on one or both sides of the sheet prior to complete drying. Fabric maintained under tension by tentering bands passes from 1 to bath 2 of calcium chloride or nitrate coagulant solution and thence under air blower 3. The fabric then passes into prevulcanized latex bath 5 and over arcuate perforated template 6 having comb-like teeth so that defined perforated strips are produced in the sheet by nozzles in air blower 7 positioned opposite spaces between adjacent teeth. The fabric is dried in 9.

Abstract: 429,081. Speed governors. SOC. GENERALE DES CARBURATEURS ZENITH, 10, Rue Petitot, Geneva, Switzerland. Sept. 18, 1934, No. 26812. Convention date, Sept. 18, 1933. [Class 57] The regulating member 3 of a fuel injection pump 1 is connected to a link 6 which is pivoted at 7 to the sleeve 9 of a centrifugal governor 10 driven by the camshaft 2. The link 6 is connected to a rod 14 actuated by a pedal 13 loaded by a spring 16. The position of idle running of the pedal 13 is determined by the stop 15 and the position for delivering the maximum amount of fuel is determined by the collar 17 engaging the surface 18. The centrifugal governor 10 is loaded by three springs 25, 32, 33. The spring 25 controls the idling speed and the spring 32 is pre-compressed between collars 21, 28 and when the speed reaches a maximum the spring 32 quickly collapses to reduce the fuel supply. The spring 33 engages the collar 28 and is engaged by the collar 35 on the sleeve 9 at a speed slightly greater than idling speed. The spring 33 is such that the load required to crush it is great and it gradually diminishes the maximum amount of fuel that can be delivered as the normal working speed increases. The spring 33 may be pre-compressed and the collar 28 may be provided with a sleeve surrounding the spring and determining the amount it may be compressed by the governor sleeve movement. The arrangement of the springs in the governor may be varied. Fig. 6 shows one arrangement wherein the weights 65 are pivoted at 66 and projections 81 engage a plate 80 connected to a rod 84. A pin 85 engages a link 61 connected to the regulating member 58. The pedal 13 is connected to a crank-pin 62 upon which the link 61 is pivoted. The idling speed spring 87 engages the rod 84 and the maximum speed spring 70 is mounted upon a rod 69. The normal running speed spring comprises Belleville washers 75 which are engaged by forks 77 integral with the weights 65.

Abstract: 191,470. B÷hm, J. Oct. 12, 1921. Pencil-sharpeners. - In pencil-sharpeners of the kind in which a disc formed of or carrying abrasive material is rotated at high speed whilst a holder for the pencil is rotated at lower speed, the pencil being pressed by spring against the disc to form a conical point, the holder comprises an adjustable chuck arranged within a toothed wheel for rotating the pencil and carried by a lever resiliently fulcrummed and urged by springs to press the pencil against the disc. The holder may be axially adjusted relatively to the disc by adjustment of the fulcrum of the lever. A disc 5 of abrasive material is removably mounted on a bevelled disc 4, preferably by means of a nut 6. The spindle 1 of the disc 4 is mounted in the frame 21 of the sharpener and is pressed upwards by a spring 3, Fig. 1, against an axially adjustable pin 15.
