Filed: 1968-01-08
Abstract: 1,147,840. Olefin copolymer rubber compositions. ESSO RESEARCH & ENG. CO. 8 Jan., 1968, No. 1066/68. Heading C3P. Oil extended rubbers are prepared by allowing a rubber comprising a copolymer of at least two mono-olefins to stand for at least 10 per cent of the time necessary for all the oil to become diffused in the rubber in up to 350 parts by weight, per 100 parts of rubber, of oil with substantially no mixing until oil has diffused into the rubber. The rubber may be a copolymer of ethylene with propylene, butene - 1 or hexene - 1, optionally together with 1,5 - hexadiene, 1,5 - octadiene, dicyclopentadiene or 2-alkyl norbornadienes. The oil may be a paraffinic or naphthenic mineral oil, or a synthetic ester oil. The rate of diffusion may be increased by heating, or by using hot oil. The extended rubbers may be mixed with conventional fillers, vulcanizing ingredients, softeners and processing aids. In examples ethylene/propylene/methylene norbornene terpolymer rubbers are extended with naphthenic and paraffinic mineral oils.

Abstract: 764,348. Angular bending; coiling. COMPAGNE DE PONT-A.-MOUSSON. Jan. 13, 1955 [Jan. 15, 1954; April 30, 1954], No. 1109/55. Class 83 (4). A bending pattern is secured to a pipe &c. to be bent and is engaged by a follower carried by a chassis movable along the pipe, the chassis also carrying means for heating the pipe on the inside of the band. A pipe T to be bent in a horizontal plane is held at one end by jaws 1, 2, its free end being supported by a carriage 4 having a roller 5 engaging a fixed runway 6. Mounted on the pipe is a chassis C comprising rear bars 11, front bars 12, rear uprights 13, cross-members 14 and strengthening stays 15; when the chassis is in position on the pipe, the front bars 12 are connected together by spacer elements 16 held fast by keys 17. Rollers 18 adjustably mounted in the chassis engage the pipe. A roller 22 adjustably mounted in the chassis engages a bending pattern 9 secured to the pipe by a strap 8. The chassis also carries burners 28 surrounded by a casing 25, 26 lined with asbestos 27. A support 33 secured to the pipe carries a winch 32, the cable 31 passing round a pulley 30 on the end of the chassis, a return pulley 34 and having secured to its end a weight 35. In operation, the winch 32 is actuated to raise the weight; as the pipe softens under the action of the heaters, the weight 35 pulls the chassis along the pipe, the engagement of the roller 22 with the bending pattern 9 effecting the bend. To continue the bend, a roller 38, Fig. 3, is mounted on the chassis so as to contact the bent portion which thus acts as a bending pattern. The bending pattern 9 may be shaped to produce twisted bends. An abutment may be fixed on the pipe at the required position to actuate a switch on the chassis so as to give a signal denoting the end of the bending operation. In a modification, the chassis C<SP>1</SP>, Fig. 8, comprises a metal beam 69 on which are carried rollers 70, 71 for guiding the chassis along the pipe T<SP>1</SP>, and a roller 72 which co-operates with the bending pattern 57 secured to the pipe by a strap 55. The chassis also carries burners 90 enclosed in a casing 85, 86. A carriage D, Fig. 13, has rollers 59 engaging the pipe and is normally latched to the template 57 by the hook end 66 of a pivoted lever 62. When the follower roller 72 has traversed the pattern 57 it first contacts the end 67 of the lever 62 to release the carriage D from the pattern 57 and then engages a part 68 on the carriage D so as to move the latter along the pipe to continue the bending operation. The chassis C<SP>1</SP> is urged along the pipe by a weight 100 and cable 95. Electric heaters may be used instead of burners;

Abstract: 1341789 Making piston and piston-rod assemblies; welding by pressure; milling GENERAL MOTORS CORP 13 Jan 1972 [16 Feb1971] 1594/72 Headings B3A B3Kand B3R [Also in Division F2] A method of making a piston 24 and pistonrod 20 sub-assembly for an hydraulic shock absorber, Fig. 1, comprises forming a piston-rod with a tapered end having a weld projection 70, cold forming a hollow piston 38, forming a weld surface 48 and flow passages 52 in the piston, electrically welding the rod 20 to the surface 48, placing valving components 26, 28, 30, 32, 34, 36 in the piston and deforming an upstanding flange 42 to hold the components in place. The surface 48 is cut by a milling cutter 47, Fig. 3, so as to leave an annular dam 50 between the surface and the flow openings 52. The interior of the piston is formed by a cutting tool 54, which forms an inclined surface 56 intersecting the openings 52, an annular shoulder 44 and a bevelled surface 46. A tool 62 forms an annular seal seat 60 on the periphery of the piston 38. A nylon seal member 64 is slipped over the base of the piston into the seat. The piston-rod 20 is placed in a locating jaw 78 of a fixture, Fig. 7, and the piston is located concentrically with the rod by an expanding collet 84, which engages the seal. An electrode 90 is located in electrical contact with the rod and an electrode 92 is placed inside the piston. The rod 20 and electrode 92 are forced against the piston and D.C. current is passed to the electrodes. The axial load is maintained during a number of weld cycles, a cycle comprising a period of <SP>1</SP>/ 60 th of a second, and the tip of the rod, which is partspherical, is deformed to fill the space bounded by the surface 48 and dam 50. The dam prevents the flow of molten material into the openings 52. Weld current passes through the electrodes 90, 92 for a lesser number of cycles initially at a constant peak level, and then is progressively decreased. The pressure is maintained with no current during a quench period and a lesser current is then passed through the electrodes during a temper period. The joined piston and rod are removed from the fixture. A spring 26, which supports an intake valve 28 is placed on the shoulder 44. An orifice plate 30 is placed on the bevelled shoulder 46 and a rebound valve 32 and spring 34 are located in a recess in the plate. A valve cage 36 is placed on the spring 34, which is then compressed to bring an annular flange on the cage within the piston 38, and the flange 42 is spun over the valve assembly.

A method of making a seamless metal tube comprises forming a hollow and delivering it to the inlet side of a skew rolling mill, advancing a mandrel bar into the hollow through the rear end, positioning the mandrel at the rolls and skew rolling the hollow over the mandrel while the mandrel bar is in tension. The hollow may be in the form of a " bottle " or open at both ends, and formed, for example, by piercing a hollow billet which is treated in a plug mill, a push bench or a continuous seamless tube mill. Alternatively the hollow may be produced in a rotary piercing mill or in a plant comprising a system of piercing followed by a pilger mill. Billets are delivered to a piercing mill 6 from a furnace 1, pierced and delivered to a roller table 9 where apparatus 13 inserts a mandrel 30 on a bar 14 into the hollow 7, pusher rolls 15 then feeding the assembly between skew rolls 16 which feed the elongated work away from the mandrel. From the rolls 16 the tubes may pass to polishing rolls 21 and thence to sizing rolls 25, after reheating by a furnace 24. The mandrel bar 14 which, with the mandrel 30 may be hollow to allow the circulation of cooling fluid, is mounted in a thrust-block 32 carried by the piston of an air cylinder 51, by which it may be moved towards a guide block 50 until the faces 52, 53 are in contact, thus positioning the plug axially in the billet. The thrust block may be returned to the position shown, Fig. 5, under the action of a weight 54. The mandrel may be replaced by others of different size. Guide shoes 33, Fig. 4, prevent ovalling of the tube and guide the work.

Abstract: Chlorine is passed into a solution of rubber containing sulphur until a jelly-like product separates, when the passage of the chlorine is stopped to prevent resolution of the product in the solvent.  This product rises to the surface and is removed, washed with solvent, treated with boiling water to remove residual solvent, and dried. The product is a semi-transparent, hard, tough, elastic substance which is mouldable at 130-140 DEG  C.  Its properties may be modified by the addition of metallic halides, oils, turpentine, chlorinated hydrocarbons, tricresyl phosphate, butyl acetate, ethereal oils, softeners such as are used with cellulose plastics, fillers, colours, synthetic resins &c. which may be introduced before, during, or after the chlorination. According to an example, 10 parts of masticated cr<\>zepe and 1.5 parts of sulphur are dispersed in 320 parts of carbon tetrachloride.  Chlorine is passed in with stirring until a stiff mass is formed.  The passage of chlorine is discontinued, and on standing for several hours, the product rises to the surface. This is removed, washed with carbon tetrachloride, boiled with water and dried.  It contains about 20 per cent of combined chlorine.
