An axle casing for a motor road vehicle is made by prefabricating an axle centre 10, Fig. 1, and a pair of tubular arms 12, holding these parts in assembled alignment, and welding them together by depositing weld metal in adjoining circumferential grooves in the ends of the axle centre 10 and the arms 12. The parts 10, 12 are rotatably mounted in a jig 11 by a motor 14 under a submerged arc welding head 15 whilst held together by bolts 13. The arms 12 and axle centre 10 are formed with spigots 17, Fig. 2, and sockets 18 at the joints to be welded. Brake attachment flanges 19 and spring seats and attachment ears 20, 21 are formed integral with the arms 12, or are welded thereto. The axle centre 10 is a cast or forged bowl or may be fabricated from plate. The arms 12 are forged solid and then trepanned, forged partially hollow and then bored, or are completely pierced during forging. In a modification, Fig. 3, the welded joints 16 are backed by a metal sleeve 22.

Title: Improvements in the production of olefin copolymers
IPC: C08F2/22
Filed: 1965-09-29
Abstract: Copolymers are prepared by copolymerizing (a) an olefin monomer and a vinyl monomer (i.e. a compound containing a substituted or unsubstituted CH2 = CH- group) to form a binary copolymer wherein the units derived from the olefin and vinyl monomers are in a weight ratio of 9-90:91-10, or (b) acrylonitrile, isobutylene and a said vinyl monomer to form a ternary copolymer wherein the respective monomer units are in a weight ratio of 50-70:10-30:5-35; the reaction vessel and all liquid reaction components being deoxygenated before the reaction to contain less than 1 p.p.m. by weight of free oxygen, and the reaction being conducted in aqueous emulsion in the presence of a polymerization catalyst and under autogenous pressure at a temperature of 25-75 DEG  C.  Suitable olefins include isobutylene, 3,3-dimethylbutene-1, 2-methyl-pentene-1 and hexene-1.  Vinyl monomers specified are acrylonitrile, methacrylonitrile, alkyl acrylates, methacrylates, maleates and fumarates having up to 8 carbon atoms in the alkyl groups which may possibly be substituted (e.g. 2-cyanoethyl acrylate), vinyl acetate, vinyl chloride, vinylidene chloride, styrene and its derivatives (e.g. p-chloro-styrene), and methyl vinyl ketone.  Polymerization can be intiated with catalysts such as organic peroxides and hydroperoxides and systems such as potassium persulphate/sodium bisulphite and hydrogen peroxide/Fe3+.  The reaction includes an emulsifier, e.g. sodium lauryl sulphate, sodium alkylbenzene sulphonates, sodium sulphonates of the formula <FORM:1116990/C3/1> and alkylphenol polyethyleneglycol ethers.  The polymer can be obtained in the form of a fine white granular powder.  In examples, the polymerization is effected at a pH of 2-5.  The polymers, with or without additives, can be formed into coatings, films, moulded articles, fibres and sheets; also, the polymer emulsions can be used directly for impregnating or coating textiles or paper.

Abstract: 859,241. Testing electric lamps. SYLVANIA ELECTRIC PRODUCTS Inc. Dec. 24, 1958 [Dec. 26, 1957], No. 41772/58. Class 39(2). [Also in Groups XXX and XXXVI] Apparatus for inspecting an electric lamp, e.g. a photo-flash bulb, to determine whether a coating of non-conducting material is present on a selected portion of the base comprises a holder for supporting the lamp, electrically conducting fingers movable into engagement with the selected portion of the base and an electric circuit including means responsive only to flow of current through the fingers and the base to actuate a holder so as release the lamp. An indexing device for inspecting simul-- taneously two sets of five lamps each is described, in which the lamps are carried by pairs of arms 12, 14 which grip the base, the arms being geared together and carried by a support 20 having a wheel 40 running in a channel 44. The supports 20 are connected to links 24 of an endless conveyer, each link having wheels 42 running in a channel 46. As each set of lamps is brought to the testing position, a contact bar 52 is advanced into contact with the lamp base by a bell crank lever 58, the other arm of which carries a cam roller 72 engaging a cam bar 76 carried by a driven shaft 78 reciprocated by a rocker arm 84 operated by a cam follower 88 riding in a trough in a cam 90 on a cam shaft 92. The shaft 78 also carries a plunger support 102 having plungers 106 in axial alignment with the lamps, forward movement of which advances a block 112 operating through links 122 to bring contact fingers 130 into contact with the selected area of the lamp bases. The reject device, Fig. 5 (not shown), to which the set of lamps is then moved comprises a set of solenoids 152 acting on cam follwers 36 to open the jaws 12, 14, a solenoid being actuated only if a current has passed through the fingers 130 as a result of contact with a defective lamp. On opening the jaws, the lamps falls into a reject bin. A second set of cam follwers are operated at the unloading station to release the lamps that have passed the test. Current through the fingers 130 closes contacts 7, Fig. 6, in a series of identical circuits, one for each lamp. A cam operated time switch 9 now closes, energizing a coil 11 to close contacts 11a and thereby energize a coil 13 closing contacts 13a, 13b. Next a cam operated time switch closes, energizing a coil 17 to close contact 17a to keep the coil 13 energized. When the lamps reach the reject device, a cam operated time switch 19 closes, energizing a coil 21 to close contacts 21a so that current flows via contacts 21a and 13b to energize the solenoid 23 (solenoid 152 in Fig. 5) to effect relase of the defective lamps.
