Abstract: 995,009. Seats. E. D. DALL. May 31, 1962 [June 7, 1961], No. 20957/62. Heading A4J. An adjustable seat structure comprises a base frame having front and rear structural rails 23, 24 joined together by tubular side rails 25 which are telescoped over tubular supports 30 adapted to be fixed to the floor, each side rail 25 being movable longitudinally in relation to its support 30 and releasable means being provided to hold the base frame in selected position on the support 30. As shown in Fig. 2 a rod 54 fixed to the base frame extends within a coil spring 53 in each support 30 to engage a closed end of the spring for yieldingly urging the base frame in one direction along the support. Roller bearing means 34 are interposed between the telescoping surfaces of the tubular supports 30 and side rails 25, hardened tubular sleeves 39, 40 being provided. Each side rail has a pair of downwardly extending flanges 28, 29 having a plurality of longitudinally spaced teeth 41. The support 30 has a downwardly extending web 31 extending between the flanges 28, 29 and adapted to be fixed to the floor. A latch 42 is pivoted at 44 on tabs 43 bent outwardly from each web 31. An ear 45 on each latch selectively engages the teeth 41. A link 49 connects the latches on each side of the seat and a handle extends from the latch 42 on the driver's side of the seat to pivot both latches. In a modification, shown in Figs. 9 and 10, up and down adjustment of both the forward and rear ends of the seat may be effected. A web 31a integral with the support is mounted for vertical movement between brackets 60a, 60b. Notches 64 are provided at the forward edge of the web 31a and notches 65 at the rear edge of the web. A latch 66 is provided with a pin 68 extending through an opening 69 in the bracket 60a. The pin 68 selectively engages one of the notches 64 and when the upper end of the latch 66 moves forwardly the pin 68 disengages from the notch 64. A second latch 70 is provided which on forward movement disengages a pin 71 from a notch 65. The lower ends of the latches 66, 70 are connected by a link. A spring 76 also connects the latches to urge the pins 68, 71 into engagement with the notches. The pins 71 comprise portions of a single rod 71 (Fig. 10), a handle 75 being provided. When the handle 75 is swung forwardly the rod 71 remains in engagement with the notches 65 whilst the pins 68 are disengaged from the notches 64. This permits the front end of the seat to be adjusted upwardly with the rod 71 forming the pivot. When the handle 75 is swung rearwardly the pins 68 act as the pivot for adjustment of the rear end of the seat. Specification 995,133 is referred to.

Abstract: 501,959. Making welded tubes. POWER FLEXIBLE TUBING CO., Ltd. July 15, 1938, No. 21090. Convention date, June 13. [Classes 83 (ii) and 83 (iv)) Drawing ; tube-expanders ;separating mandrels from work.-In an apparatus for making round, oval, or polygonal electrically lap welded tubes from metal strip in a continuous operation by sectioning the strip, resistance welding the seam and sizing and straightening the. tube, the open tube, as formed, together with a tubular or rod-shaped internal electrode carrying a sizing and straightening tool is drawn through a die and the tube welded by a non-displaceable roller electrode extending through a slot in the die, and the tube is then held fast and the inner electrode and sizing and straightening tools are drawn back to finish and straighten the tube. Strip metal 7 is drawn from a reel by a draw bench 20 through a curling channel 4 and a copper or bronze die 3, the channel being angularly adjustable by a lever 9. Through the die, which is slotted for the passage of a roller electrode 14 passes one or a number of connected copper tubes &c. forming an internal electrode 13 of tubular form for large tubes or solid for smaller tubes, and carrying at one end a sizing ring 25 and a straightening mandrel 28. The inner electrode is of slightly smaller diameter than the internal diameter of the tube. The mandrel may be drilled at 30 and receive the end of a tube 29 through which grease may be supplied to the cavity 27 by a grease gun. One terminal of the circuit of a transformer is connected to the roller electrode and the other to the internal electrode via a shoe 15 or roller, the die 3 and a tube support 11 being also connected to this terminal when welding small tubes. The end of the tube is secured by a tapered hollow pin 23 in a bush 22, which has trunnions 24 normally engaging in slots in the draw-bench slide 21. The slide 21 is connected by a wire cable 34 which passes over rollers 35, 35<1>, 35<2>, 35<3>, to the rear end of the inner electrode. This electrode together with the tube is drawn by the slide 21 through the die 3 and the tube welded at the electrode 14, which may be water-cooled inside and out. The cooling water may be allowed to run over the tube. In order to withdraw the inner electrode &c. after welding the bush 22 is held by hooks 321 on the bench and the slide 21 is retracted preferably at an increased speed, so as to effect the sizing and straightening operations. The cable twists due to tension in this rearward stroke and thus adjusts the inner electrode angularly so as to use different parts of the periphery for successive operations. The welded tubes may be cut off behind the straightening mandrel. The apparatus may be used for thin tubes or for thick tubes with chamfered edges.

Title: Process for treating copper- and zinc-containing lyes
IPC: C22B3/44
Filed: 1927-08-11
Abstract: 276,008. Grothe, H., and Metallh³tte Magdeburg Ges. Aug. 11, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Cuprous chloride; zinc salts; cobalt salts.-The cupric salts present in liquors obtained by lixiviating chlorinated roasted pyrites are reduced wholly or partly to cuprous salts, principally ouprous chloride, as by means of sulphurous acid, thiosulphate, sulphides, or metals. The cuprous salt may be separated, and the copper remaining in the liquor be precipitated by cementation with iron. When the lixiviation liquors comprise a portion rich in zinc and chloride but poor in copper, and a portion rich in copper but poor in zinc and chloride, the copper content of the latter only may be reduced to the cuprous state. After partial separation of cuprous chloride, acid liberated by its formation may be entirely or partly neutralized by zinc oxide-bearing waste products prior to cementation to remove remaining copper. In treating chlorinated roasted pyrites containing equal amounts of copper and zinc, solutions were obtained containing, respectively, 55-60 per cent of the zinc and 10 per cent of the copper, and the remaining zinc and copper; the former was treated with scrap iron directly; the latter was treated with sulphurous acid or sodium bisulphite, whereby 80 per cent of its copper content was separated as cuprous chloride, the remaining solution, after neutralization with zinc oxide, being treated by cementation. The two copper free solutions so obtained were combined, cooled to separate sodium sulphate, and thereafter treated for recovery of their zinc and cobalt contents.
