Title: Vulcanisation process
IPC: C08L21/00
Filed: 1960-07-06
Abstract: In the vulcanization of natural rubber and elastomeric copolymers of butadiene and styrene or acrylonitrile, there is employed as a vulcanizing agent a substituted phenol resin, prepared by the alkaline condensation of formaldehyde with one or more phenols which are substituted in the para position with a substituent containing at least three carbon atoms, together with a metal halide which can act as an "ansolvo" acid; the metal halide may be formed in situ prior to or during vulcanization. The para substituent of the phenol may be an alkyl, aryl or aralkyl radical such as tertiary butyl, diisobutyl, octyl, phenol or benzyl; the phenol and formaldehyde are preferably reacted in the presence of aqueous caustic soda at 50 DEG -70 DEG C. Preferred metal halides are stannous chloride dihydrate and zinc chloride; alternatively the compound may be formed in situ from a metal oxide or salt and a compound which splits off halogen or a hydrogen halide such as a halogen-containing vinyl polymer or copolymer, e.g. polyvinyl chloride, a polychloroprene, chlorosulphonated polyethylene or chlorinated paraffin.  One to four parts of the metal halide are used for each 100 parts of the rubber, to which fillers, such as carbon and silicic acid, and other vulcanizing agents may be added; vulcanizing temperatures within the range 120 DEG -180 DEG C. are preferably employed.  In Examples, (1) butadiene-styrene, butadiene-acrylonitrile, or natural rubber is rolled to a smooth consistency on a roll mill, and stearic acid, carbon black, spindle oil or plasticizer, phenolic resin, and stannous chloride dihydrate are then mixed in; the vulcanization was performed at 154 DEG C. for periods ranging from 15 to 45 minutes, (2) a similar vulcanization procedure is employed with mixtures consisting of butadiene-styrene, stearic acid, carbon black, phenolic resin, polyvinyl chloride or chlorosulphonated polyethylene, and zinc oxide, (3) a rolled pre-mixture of polyvinyl chloride and zinc oxide was mixed with butadiene-acrylonitrile, stearic acid, carbon black, and phenolic resin; the mixture was vulcanized at 154 DEG C. for 45 minutes.  The phenolic resin employed in the above examples was produced by dissolving 206 g. of p-octyl phenol in 400 g. of 10% aqueous sodium hydroxide at 80 DEG  to 90 DEG C., cooling the solution to 60 DEG C. and adding 40 to 60 g. of 30% formaldehyde solution over a period of 4 to 3 hours.  At this point the mixture is cooled, neutralized with dilute sulphuric acid and washed free from sulphate with water.  The salt- and acid-free residue is dehydrated in vacuo up to 80 DEG C. and converted into a solid resin by heating up to 150 DEG C. under normal pressures.  Specification 880,756 is referred to.

Abstract: 620,772. Supply systems for lighting &c. SCOLES, G..J., WHALLEY, H., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Aug. 21, 1946, No. 24918. [Class 38 (iv)] [Also in Group XL (c)] A circuit for controlling the power, fed from an A.C. supply, for example to a lighting circuit, comprises means for generating a time base voltage during each cycle of the supply voltage and a further circuit, which at a determinable point along the time base trips a valve which is rendered conducting and supplies power to the load circuit. In the Figure, capacitor C1 charges through resistor R1 until the positive half-cycle of the supply voltage fed in at A causes valve V to conduct and discharge capacitor C1. Valve V3 is normally conducting and valve V2 is cut off by the bias voltage developed across the common cathode resistor R2. As the voltage across C1 rises during the charging cycle a point is reached dependent upon the setting of the potentiometer R5, when valve V2 conducts and valve V3 is cut off. The positive going pulse at the anode of V3 is differentiated by the network C2, R4 and the positive pulse triggers the gas-filled valve V4 which applies an A.C. supply connected across its anode-cathode circuit to a load L.

Title: Explosive forming method and apparatus
IPC: B21D26/08
Filed: 1960-07-12
Abstract: 925,422. Stamping; making cylinders; sizing and restoring shape of articles. AEROJET-GENERAL CORPORATION. July 12, 1960 [July 27, 1959], No. 24303/60. Classes 83 (2) and 83 (4). A method of fabricating a metal member includes the steps of arranging a metal blank so that it faces the contoured surface of a die, submerging the blank and die in a fluid body and detonating an explosive charge submerged in the fluid body. Apparatus for carrying out the method comprises a frame 4 mounted on supports 6 and carrying a die 8 embedded in concrete or lead 12. A steel blank 20 is clamped to the die in a fluid-tight manner by a hold-down ring 24. An explosive charge 32 is suspended above the blank on a member 34 attached to the frame 4. The die cavity 9 is evacuated through a vacuum line 10 and the apparatus is placed on the bottom of a tank 16 which is set in the ground and filled with water 14. The explosive charge is then fired to deform the blanks into the die cavity. A watersoluble lubricant is used on the die to assist the cupping operation and to facilitate removal of the formed blank from the die. The products of detonation form an oscillating gas bubble which aids in the cupping operation by producing a hammering effect on the blank. In another embodiment a cylinder 42 is sized by placing it in a split die 38. The air in the cavity surrounding the cylinder and the die is evacuated through a pipe 45, a string explosive charge 46 is suspended in the cylinder which is then filled with water or oil and the unit submerged in a tank of water as in the previous embodiment. To eliminate spring-back when explosive forming high strength metals, e.g. nickel, chrome and vanadium steels, the die is lined with a resilient material 58, e.g. rubber, Fig. 5. Alternatively, the liner is glued to the underside of the blank. Where a progressive draw is desired the use of an additional die is eliminated by first forming the blank with the liner in position and then reforming the blank with the liner removed. To prevent buckling and wrinkling the blank is sandwiched between upper and lower metal blanks and the assemble glued or otherwise bonded together to form a composite blank. After the explosive forming the blanks are separated and then individually trued to a final contour. In a further embodiment the explosive impulse is utilized as a hold-down on the blank by providing above the explosive charge a reflector 100 suspended from a holding member 98 arranged across the top of the tank 78, Fig. 7. By varying the thickness of the explosive charge in a radial direction the amplitude of the hold-down shock is controlled. Large blanks comprising a plurality of small blanks welded together can be formed according to the invention without weld failure. In a further embodiment, a male die 118 is used to form the blank into a domed configuration, Fig. 10. To achieve a uniform thickness in the formed article the initial blank is shaped as shown in Fig. 11a U.S.A. Specification 2,895,405 is referred to.
