Abstract: 1,132,520. Making electrical contacts; forging; welding by pressure. MALLORY METALLURGICAL PRODUCTS Ltd. 21 Oct., 1966 [2 Nov., 1965], No. 47158/66. Headings B3A, B3H and B3R. A method of making a bi-metallic electrical contact, e.g. a rivet type contact, comprises shearing a disc from a wire of contact metal, shearing a length from wire of base metal or alloy thereof, placing the disc and wire in a die and joining their mating surfaces by pressure exerted under the impact of a fast moving weight. Copper wire is fed from a combined feeding, measuring and straightening device 100 and sheared by cutter means 31 into lengths 18. Each length 18 is heated in a device 33 which positions the length over a hole 16 in a carbide die 14. Meanwhile a disc 17 of silver or silver cadmium oxide is sheared from wire by a cutter 32 and the disc is carried by the cutter blade to a position directly above the length of copper. A guide assembly 98 is moved directly over the die 14 and when in position a weight 102 is impelled downwardly, passing through a hole 97 in the guide assembly to drive a punch holder 96 and punch 12 thereby forcing the length 18 and disc 17 against a carbide ram 15. The ram shapes the bottom of the shank of the rivet and the remaining energy in the weight 102 welds the two metals together before rebounding from the die. An hydraulic piston 20 is elevated driving a rod 106 and the ram 15 and the welded composite rod 25 is forced upwardly to a position 109 when the piston reaches the end of its stroke. The head of the rivet is shaped by tools (40), (36), Figs. 11, 12 (not shown), which are struck by the weight 102. To eject the rivet from the die 14, an hydraulic piston 111 is elevated and it contacts the rod 106 in the position where it was left by the piston 20 thereby forcing the ram 15 and rivet upwardly. A projection on the tool (40) carries the rivet to a storage space, Fig. 14 (not shown). Cooling liquid is circulated through a passage 117 in a ring 116 and a viscous liquid is introduced into the interstices between the ring and the die to help the passage of heat. The base 95 is watercooled and the various tools are mounted on blocks of copper alloy to assist in conducting heat to the base. All these operations are performed automatically in a vacuum chamber 30.

Title: Electrodeposition of organic film-forming coatings
Inventor: BURDEN JOHN PETER
Filed: 1962-12-17
Abstract: Conductive articles, e.g. steel panels, are coated by electrodeposition while immersed in an aqueous film-forming coating composition containing an ionic cross-linkable organic filmforming material soluble in the aqueous phase of the composition, the article then being removed from the composition and cross-linking effected. Typically the composition contains by weight 5 to 10% of non-volatile material, up to 10% of a polar water-miscible organic liquid and may contain pigment in a volume concentration (P.V.C.) up to 30% of the ionic cross-linkable material.  If the P.V.C. is reduced to 10% or less pitting of the coating is avoided.  The composition may contain a resin with free acid groups and be solubilized by ammonia or an amine to give an alkaline solution for anodic coating e.g. with a varnish linseed oil - maleic anhydride resin, an acrylate resin, an alkyd resin from propylene glycol, trimellitic anhydride, phthalic anhydride and coconut oil fatty acid; or a resin with free amine groups neutralized with an acid to give an acid solution for cathodic coating, e.g. with a polyamide resin.  The compositions may include cross-linking agents and are used at a pH of 0.3 to 1.0 unit on the stable side of their instability point.  After drying, the coated articles are stoved, e.g. at 150 to 165 DEG C., to effect crosslinking.

Title: System and method of weighing coupled railroad cars in motion
IPC: G01G19/04
Filed: 1962-12-18
Abstract: 979, 913. Weighing coupled rail cars. H. A. L. VENNER. (S.H. Levinson). Dec. 18, 1962, No. 47778/62. Heading G1W. A method of weighing coupled railroad cars while in motion in which the cars are passed over a weigh rail 16 and weighed, comprises altering the distance between adjacent cars an amount sufficient to free the joined couplers 7, 7<SP>1</SP>, Fig. 1 of forces in draught for a time sufficient to permit the couplers to drop by gravity to a predetermined position, as in Fig. 2, if they are not already in such position, then increasing the distance between the cars an amount sufficient to cause the couplers to engage in draught before the car to be weighed reaches the weigh rail, and maintaining the cars coupled in draught until after the car being weighed has passed over the weigh rail. An engine E, Fig. 6, draws railroad cars A, B, C, D along a track 15 containing the weigh rail 16. The cars are coupled by couplers 7, 7<SP>1</SP> having the form shown in Figs. 1, 9 and the couplers are mounted on keys 9 with springs 8, 8<SP>1</SP> to absorb shocks, the couplers having a vertical play between upper and lower sills 6, 6<SP>1</SP> and 5, 5<SP>1</SP> respectively, on the cars. If the couplers are in the positions shown in Figs. 1, 2 the cars may be weighed accurately since there can be no transfer of weight from one car to the next. However, with the couplers in a position such as that shown in Fig. 5, weight may be transferred and to overcome this the tank 15 has inclined sections 19, 20 arranged as shown in Fig. 6. The coupling between the cars B, C will be in the condition shown in Fig. 2, where the couplers rest on the lower sills 5, 5<SP>1</SP> and this will automatically occur whatever the previous positions of the couplers. The couplers between the cars B, A and A, D are in the condition shown in Fig. 1, and by the time the cars have reached the position of the car D in Fig. 6, the car is free from jolting and is being pulled steadily by the engine E, the car thus being in proper condition for weighing, the weight being transmitted to an indicator a recorder 18, which allows for the inclination of the weigh rail 16. The upwardly inclined track section 20 may be replaced by a level rail section fitted with retarders, (Fig. 7, not shown), or on a level rail, a retarder may be provided, at the position of the car B in Fig. 6 to provide the same effect of temporarily relieving the couplers of horizontal forces, (Fig. 8, not shown). Also, the weigh rail may be such as to give a weight reading for part of a car only, e.g. one axle loading, and the engine E may alternatively be arranged to push the cars over the weigh rail.
