Inventor: LEWIS JOHN RICHARD
IPC: C08F242/00
Filed: 1957-04-01
Abstract: Copolymers of conjugated drying oil-modified alkyd resins and aromatic vinyl monomers and/or methacrylate esters are obtained by adding the alkyd resin, the unsaturated monomer and the polymerization catalyst stepwise and simultaneously to a solvent medium heated to the polymerization temperature.  Alkyd resins specified are those obtained by modifying phthalic anhydride-glycerin alkyds with castor oil, which may be used alone or in admixture with a soya bean oil partial glyceride or rosin, tung oil and isomerised drying oils.  Monomers specified are styrene, vinyl toluene and lower alkyl methacrylates. Catalysts specified are tert-butyl and cumene hydroperoxides, di-tert-butyl peroxide and azodiisobutyronitrile. Solvents specified are toluene, xylene and mesitylene which may contain a proportion of mineral spirits or, in the case of vinyl toluene, may be entirely replaced by mineral spirits.  The solvent may initially contain a minor proportion of an alkyd resin which may or may not be the same as the alkyd resin added subsequently. Also present during polymerization may be modifiers such as mercaptans, chlorinated hydrocarbons and terpenes, e.g. dipentene.

Metal rings or the like 9, such as anti-friction bearing-rings, are made by upsetting the heated end of a clamped bar M within a die cavity 10 by means of a mandrel 4, unclamping the bar, further advancing the mandrel to pierce the upset portion and sever it from the remainder of the bar and further upsetting the severed off portion by means of an upsetting bushing 13. The mandrel is mounted on a reciprocating ram 5 and slidably carries the upsetting bushing 13. During the advance of the ram the heated bar M is clamped against a fixed jaw 2 in the die block 3, by a moving jaw 1 actuated through link 7 and roller follower 6 by a cam track 8 on the ram. The mandrel 4 upsets the end of the bar and the latter is then unclamped as the follower 6 runs off the cam track. Mandrel 4 then pierces and severs off the upset portion and it is further upset by bushing 13 which is engaged by the mandrel holder 12 of the ram. During the return stroke the follower 6 is diverted from the cam track to leave the bar unclamped and it is fed forwardly by a wedge-operated reciprocating gripper 22, Fig. 3 (not shown), actuated by linkage 20, 17 from the ram. The stroke of the gripper is adjusted by a screw 19. In another embodiment, Fig. 4 (not shown), the clamping- jaw 1 is actuated by a rotating cam. The depth of die cavity 10 may be less than the axial length of the required ring whereby a flange will be formed thereon between the die-block 3 and the bushing 13 during the final upsetting.

Abstract: 557,439. Cupping-presses. ABBEY, A. A. (Bliss Co., E. W.). Aug. 6, 1942, No. 11020. [Class 83 (iv)] The draw ring or blank holder 16 of a cupping press has pressure applied to it at each corner by independently adjustable hydraulic means. Lugs 56 at the corners of the holder are connected to rods 55 guided at 58 and connected to pistons in cylinders 54 each connected by a fluid link to cylinders 35 with pistons each operated by a cam 41 on the press crankshaft. Each link pipe connecting the pairs of cylinders has connected to it a pressure limiting vessel 65 containing a piston 67 loaded by a spring 72 under a pressure adjustable by a screw 74 and disc 70. Leakage from the fluid links is made good from a common reservoir 60 communicating with each cylinder 35 through a valve controlled passage controlled by solenoids and a limit switch 63 from a cam 64 so that the valves close just prior to the commencement of the pressure stroke. Further changes in pressure or stroke may be obtained by varying the relative diameters of the two cylinders in any link, by adjusting the rods 55 in the lugs 58 and by adjusting the position of the cylinders 35 on the frame at 80, Fig. 4. Cyclical variations in pressure may be obtained by shaping the periphery 77 of the cams for instance to reduce the pressure between the beginning and end of the stroke. The drawing is counterbalanced by an air cylinder 32. If the press is to be used as a triple action press further cams and fluid links are provided for the additional drawing operation.
