Title: Manufacture of a composite electrical conductor including a superconductive conductor
IPC: H01L39/06
Filed: 1974-07-01
Abstract: 1435459 Making superconductive conductors SIEMENS AG 1 July 1974 [3 July 1973] 29170/74 Heading B3A [Also in Divisions C7 and H1] A method of making a composite electrical conductor including a superconductive conductor consisting of an intermetallic compound comprises providing a starting structure formed of a ductile core which constitutes a component of the intermetallic compound and a ductile first layer surrounding the core, reducing the cross-section of the starting structure, applying a second layer made of alloy containing a carrier metal and a remaining or each remaining element of the intermetallic compound to the first layer and applying heat treatment to cause the remaining element to diffuse through the first layer and react with the core to form the intermetallic compound. The core of is Nb and the first layer is of Cu, while the second layer is of a Cu-Sn alloy containing 12% atomic of Sn. The reduction in cross-section is performed by drawing or rolling without intermediate annealing and the second layer is deposited electrolytically. Heat treatment is carried out in two stages in the first of which the alloy coated conductor is heated for several hours at about 600 C. to diffuse the Sn out of the second layer into the first layer to form a substantially uniform tin concentration in the first and second layers. In the second stage the conductor is heated at about 750 C. for about 60 hours to form a Nb 3 Sn layer at the surface of the Nb core. A multi-core conductor is made by placing a number of Nb cores 32 in a first layer 31 of Cu, e.g. a Cu rod with a series of bores into which are pushed Nb wires. Alternatively the wires may be sheathed with Cu, assembled into a bundle and placed in a Cu tube. The starting structures thus formed are cold drawn and a second layer 33 of Cu-Sn is deposited on the layer 31. Heat treatment forms layers 34 of Nb 3 Sn and an outer layer 35 of Cu-Sn alloy having approximately uniform tin concentration. If required the thickness of the layer 35 may be reduced by electro-chemical or chemical means, e.g. to the line 37. Finally a layer 36 of stabilizing metal, e.g. Ag, is deposited on the layer 35. The alloy coated conductor may be tempered for stress relief at 600-650 C. for about 5 minutes and a number of these conductors may then be braided together, Fig. 5 (not shown), to form a multi-core conductor. Alternatively the Nb cores 32 may be guided along helical paths in the layer 31. The braided conductors are subjected to homogenization annealing for about 6 hours at about 600 C. for equalizing the Sn concentration and then heated at 750 C. for about 100 hours to form the Nb 3 Sn layer. The second layer may alternatively be an Ag-Sn alloy or of Cu-Ga alloy when forming the intermetallic compound V 3 Ga. In the latter case the alloy contains 5% 30% atomic of Ga and heat treated at 500- 950 C., the temperature not being sufficiently high to fuse the Cu-Ga alloy.

Title: Power generation
Inventor: GREENWOOD JOHN
IPC: F02B3/06
Filed: 1957-09-17
Abstract: Mechanical power is obtained by distilling a crude petroleum oil to obtain a low boiling fraction having a final boiling point between 250 DEG  and 430 DEG  F. which is used to operate an engine capable of running on the fraction and wherein power and waste heat are produced, at least part of the waste heat being used to provide at least part of the heat necessary for the distillation. The process is especially suitable for use on board oil tankers, the crude cargo being used as the fuel precursor.  The crude may be butanized, e.g. with 5-6% of added butane or used as obtained from the well.  The engine used may be a diesel or oil-fired steam engine.  A storage tank is provided between distillation and engine, if desired, or, with an oil-fired steam engine, the vapours may be passed direct to the burners.  The combustion gases may be passed through heating coils in the distillation zone, or, if the fuel is used to operate a steam turbine, superheated steam can be used to provide the heat.

Void [Published under Sect. 91 of the Acts]. Purifiers comprise an inclined rotating drum 2 having scoops 28 longitudinally arranged on the inner wall. The charge is fed into the upper end of the drum and meets the gas in countercurrent; on emerging from the lower end it is recirculated by means of a conveyer. The scoops are so formed that the material falls from them in a uniform shower over the whole of the horizontal crosssection of the drum. This is effected by making them of semi-elliptic cross-section half closed along the minor axis, which is inclined at an angle of 30-40‹ to the radius of the drum.

In a continuous-cycle inert gas system the gas heat exchanger 18 is constructed so that the part of its outer surface exposed to the cabinet insulation and to the outer atmosphere is contacted on the inside by relatively warm weak inert gas from the absorber 21, to maintain its temperature above that at which atmospheric moisture would condense on the surface and give rise to corrosion. The part of the exchanger in the interior of the cabinet is constructed in the usual manner to maintain it cold. In the .arrangement shown a casing 27 is provided at the part of the exchanger outside of the storage space, warm weak inert gas flows thereto through a conduit 29, and after flowing around the shell of the exchanger to provide a triple heat exchange the weak gas passes through the tubes and through a conduit 35 to the evaporator, which comprises the usual low-temperature portion 33 and cabinet' cooling portion 16. The cold inert gas refrigerant mixture returns from the top of the evaporator to the-shell of the exchanger. In a modification the casing 27 extends downwards around the pipe 19 conveying the inert gas and refrigerant vapour to the solution reservoir 20, and weak solution is supplied from the generator to the casing and overflows therefrom into the absorber. The casing may extend over the whole of the exchanger, particularly where the exchanger is arranged within the thickness of the cabinet insulation.
