Title: Interconnecting bimetallic tubes
IPC: B23K20/00
Filed: 1974-07-04
Abstract: 1454678 Sleeve couplings SIEMENS AG 4 July 1974 [4 July 1973] 29743/74 Heading H2E The invention relates to the joining of bimetallic tubes each having an inner tubular part made of one metal and an outer tubular part of another metal, one of the metals (e.g. niobium) being superconductive at which the other (e.g. copper or aluminium) is electrically normally conductive. The method comprises the use of a normally-conductive sleeve to join the normallyconductive parts and two superconductive annular attachment members, the members being joined together and each member being attached to or formed integrally with the superconductive part of a respective tube. In Fig. 1 the attachment members 7, 8 and normally conductive inner tubes 3 are screwed 9 to the sleeve 10 and the tubes 3, 10 soldered together at 12, the members 7, 8 then being welded together by an electron beam 11, the members being welded only partly through if the sleeve metal would otherwise interfere with the weld. Fig. 10 shows how each attachment member can be made in two parts 35, 38, part 35 being inserted to replace an end portion of the normally conductive metal removed by etching or turning and a protruding end 37 of the superconductive outer layer 34 being bent round part 35 before fitting part 38, the parts then being welded together by electron beams 40, 41, 42. In an alternative construction (Fig. 11, not shown) a relatively thick tube is constructed initially, the outer superconductive layer being formed with a thicker region protruding into the normal metal near one end, this region forming the attachment member after drawing the tube to the required thickness and turning off the end of the tube beyond this region. It is also possible to provide initially a pure copper tube with a niobium attachment member, an outer niobium layer being applied later. In a further alternative construction (not shown) the tubes are made initially in the form of (e.g.) copper strips with attached (e.g.) niobium cross-webs, the whole being plated with niobium and subsequently bent and welded to form a tube with attachment member. In an alternative embodiment (Figs. 2 to 6, not shown) the superconductive layer is on the inside surface of each tube the inner sleeve being replaced by an outer sleeve, which may be split longitudinally into halves, the attachment members being welded together (and, if required, coated externally with a normally-conductive metal) prior to application of the sleeve.

Abstract: 1,165,668. Ethylene; acetylene. STONE & WEBSTER ENG. CORP. 21 June, 1968 [22 June, 1967], No. 29777/68. Heading C5E. Ethylene (major product) and acetylene (byproduct) are produced by a process comprising the following steps:- (a) cracking a hydrocarbon, e.g. ethane, propane, butane, pentane, naphtha or gas oil, suitably by steam cracking; (b) compressing the cracked gases in at least two, preferably at least four, stages, with increasing pressure in each succeeding stage; (c) fractionating the compressed gases to separate a fraction comprising a major portion of ethylene and a minor portion of acetylene; (d) treating said fraction under elevated pressure with a selective solvent for acetylene (preferably dimethyl formamide, but others mentioned) to give substantially acetylene-free ethylene and an acetylene solution containing a minor amount of ethylene; (e) removing ethylene impurity from the acetylene solution by flash evaporation in at least two stages, with reducing pressure in each succeeding stage, to a final pressure which is not less than the inlet pressure to the first compression stage in step (b); the ethylene thus released being recycled to one of the compression stages; and (f) stripping acetylene from the ethylene-free acetylene solution, e.g. by heat, the solvent being optionally recycled to step (d). The process sequence may also include the following optional steps:- (i) between (a) and (b) the cracked product may be treated with a countercurrent waterreflux to condense heavy hydrocarbons; (ii) the ethylene product from step (d) may be selectively hydrogenated to remove acetylene traces; (iii) between (e) and (f) residual ethylene impurity in the acetylene solution may be removed by stripping, e.g. with heat or acetylene; (iv) the ethylene streams from (e) and (iii) may be water-washed to remove entrained solvent before recycle to the compression step; (v) the solvent in step (d) may be saturated with gaseous ethylene.

Abstract: 933,371. Blow-moulding hollow articles. RHENOPACK G.m.b.H. Sept. 4, 1959 [Dec. 19, 1958], No. 30208/59. Class 87(2). A sheet 28 of thermoplastic material is formed into a hollow article by feeding the sheet from a roller 25 over a guide roller 27 to guide members 30, 40, 41 which bend the sheet into an inverted U-shape, Fig. 6. The sheet is pulled through the guide members by intermittently moving grippers 44. The sheet is then heated by a member 51, Fig. 7, which may be covered with fabric or may be embossed to prevent the sheet from sticking to it. The sheet is also heated by adjustably mounted side heating members 59 having reflectors 60. The position of the members 59 may be controlled automatically by thermostats (see Fig. 8, not shown). Tools 91a, 91b having electrodes connected to a high frequency generator 94 are then moved inwardly to form the longitudinal seams on the containers, as shown three containers may be formed simultaneously. When the tools 91a, 91b are closed compressed air is is supplied through pipes 101 to force the sheet into contact with the tools and shape the containers. After the containers have been formed, the pipes 101 are lowered and the tools 91a, 91b retracted. The sheet with the formed containers is then pulled along by grippers mounted on arms 133 to a position between tools 151a and 151b which are then closed to cut out the containers from the sheet. The containers are ejected from the tools by ejectors, springs or compressed air through openings 155 in the tool into a trough 156. The waste sheet which issues from the machine may be wound on a roll or may be cut into small pieces by knives 163, 164. The machine may be controlled automatically by cams on the main drive shaft (see Fig. 10, not shown).

Abstract: 364,691. Vehicle brakes. LEONARD, N., Feignies, Bord, France. Oct. 9, 1930, No. 30289. [Class 103 (i).] Fluid-pressure; transmitting mechanism; applied by weight of vehicle.-The pressure applied by the piston of a fluid-pressure brake mechanism for vehicles to the brake blocks reacts through, the transmission mechanism on a spring which takes part of the weight of the vehicle whereby when the braking pressure reaches a value dependent upon this weight a valve is actuated to cut off the supply of compressed air to .the brake cylinder. The vehicle. body with the main frame 18 is suspended from the beam 21 on the axle-box 22 by links 23 and levers 24 pivoted at 40 to frame members 25. Springs 27 are interposed between :arms 28 of the levers 24 and frame members 31 so as to take the weight of the body. The seat 29 of the springs 27 on one side of the axle-box is secured to a rod 30 slidable in the frame member 31 and provided with a stop collar 33 which normally abuts on the member 31. A rod 34 also slidable in the member 31 abuts on the end of the rod 30 and the rods on the two sides of the vehicle are connected bv a triangular member 37 to a point 45 on a lever 16 pivoted to a fixed point 17 on the frame. One end of the transmission system 11<1> by which the brake operating piston 8<1> is connected to the brake-blocks is connected by link 46 to the upper end of the lever 16 which is connected also, by link 71, to the piston 51 of a cut-off valve 10 disposed in the pipe 9 leading from the triple valve 6 to the brake cylinder 8. Normally, the piston 51 is disposed at the left-hand of the valve casing so that when the brakes are applied air is supplied - from the auxiliary reservoir 7, through port 55, passage 61 in the piston and port 53 to the brake cylinder. But when the pressure transmitted to the brake blocks 12 by the piston 8<1> and reacting through link 46 on the lever 16 and rod 34 reaches a value depending upon the vehicle load, the lever 16 and the spring 27 are displaced to the right slightly lifting the vehicle body and shifting the piston 51 of the valve 10 to the right, Fig. 3, so as to cut off further supply of air to the brake cylinder 8. The piston 51 contains a non-return valve 62 normally seated by the spring 63 and when in releasing the brakes the triple valve 6 is operated to connect the pipe 9 to atmosphere, the brake cylinder exhausts at first through passages .57, 61, 55, past the valve 62 until the braking pressure reduces sufficiently to permit the return of the lever 16 and thus the valve piston to the normalposition.
