Abstract: 279,041. Studienges. f³r Gasindustrie. Oct. 18, 1926, [Convention date]. Revaporizing liquefied gases.-Liquefied gas is delivered under pressure, from a vessel 1, Fig. 1, containing a thin-walled inner vessel 4 and surrounded by coiled tubing 5, 6 through which the liquid is passed and' after revaporization delivered to the place of use, or stored under high pressure when consumption is interrupted. Liquefied gas is supplied through a pipe 2 surrounding and cooled by the neck 3. It rises in the tube 7 and passes through the coils which are located in the space between the vessel and an outer jacket 8; this space is filled with kieselguhr or other insulating material into which gas is forced, and the jacket is made gas-tight by packing. The coils are continued outside the jacket, and lead to the delivery pipe 10. A byepass 12 leads cold gas from the neck of the vessel to cool the liquid in the inlet pipe 2. The inner vessel 4 is apertured so that the pressure on both sides is equalized. Fig. 2 shows a vessel containing a rectification column 25 the nitrogen from which passes away through a pipe 40. The pipe 29 leads from the neck of the vessel to the outlet pipe 10. Air is supplied through a pipe 34. A pipe 21 equalizes the pressure inside and outside the inner vessel. The rectification column may be outside the vessel, with which it is connected by a pipe. Both the inner vessel and the outer pressure vessel may be constructed of material the expansion of which does not alter materially even at the lowest temperatures, e.g. iron poor in carbon, rustless steel or aluminium. The difference between the temperatures at any point of the coil and that of the wall of the vessel bears a constant ratio to the distance of the point from the beginning of the coil.

Title: Improvements in or relating to absorption refrigerating apparatus
IPC: F25B33/00
Filed: 1952-09-18
Abstract: 713,147. Refrigerating. ELECTROLUX, Ltd. Sept. 18, 1952 [Sept. 22, 1951; Sept. 22, 1951], No. 23442/52. Class 29 In continuous cycle absorption refrigerating apparatus of the inert gas type having a boiler system comprising a heating tube; a boiler tube and a pump tube, and a liquid heat - exchanger all enclosed in a common body of heat insulation, one of the streams of liquid flowing through the liquid heat-exchanger receives waste heat from the boiler system at a zone outside the liquid heat-exchanger before said stream has completed its passage through the heat-exchanger. The solution entering the pump has. therefore an increased temperature. As shown in Fig. 1, the pipe connecting the absorber vessel 12 to the liquid heat-exchanger 16 is welded at 26 to the lower part of heating tube 10 so that the strong solution is preheated. The welding may be along a common generatrix as shown or peripheral. Pipe 17 carrying weak solution from the liquid heatexchanger to the top of the absorber 18 is provided with cooling fins 37 outside the boiler insulation. As shown in Fig. 3, the boiler system is of the type wherein the pump 14 raises weak solution from the bottom of the boiler pipe 11 to a stand-pipe 42. From the stand-pipe 42, weak solution flows through the first part 33 of the liquid heat-exchanger and then flows upwardly through a pipe 46 welded either along a common generatrix as shown or helically to that part 43 of the boiler 11 in which vapour exists so as to be heated. It then flows down a pipe 44 similarly welded to the heating tube 10, this being further heated. The expelled vapours are rectified in the part 43 of boiler 11. It then flows through the second part 34 of the liquid heat-exchanger. It may traverse the pipe 44 before the pipe 46. The part 33 of the liquid heat-exchanger may be omitted. Any gases formed in the liquid heat-exchanger and the pipes 44, 46 are vented to the vapour space of the boiler by a pipe 36. In a modification (Fig. 2, not shown) the pump circulates strong solution, and weak solution from the boiler flows through a first part of the liquid heat-exchanger, an inverted U-tube one or both limbs of which are welded to the heating tube and the second part of the liquid heat-exchanger. If a flame is used as the heat source, the first part of the heat-exchanger is omitted. As shown in Fig. 4, weak solution from the first part 33 of the heat-exchanger is led by a pipe 44 to a jacket 50 surrounding, the vapour space of boiler 11 and vented thereto at 52. The vapour space of boiler 11 may have internal surface-enlarging members. Heated solution then passes to the second part 34 of the heat-exchanger by pipe 46. Vapours expelled in the pump 14 are led from the top of stand pipe 42 through pipe 55 to enter the boiler 11 below the liquid level so that they are analyzed. The jacket 50 rectifies the vapours.

The outer casing walls 2 are laterally displaceable along grooves 14, and different lengths of web are defined by adjustable bases 4. The inner casing 3 is made of sheet metal or concrete, encloses heating channels for air or steam, and is closed at its ends by plates 10 that include lifting loops, projections or apertures. Partitions 5 (Fig. 6) divide up the mould cavity and are supported vertically or inclined by templates 6 and clamps 11 engaging the outer casing 2. In use, reinforcement passes through partition apertures 13, strips 28 (Fig. 5) dowels, wire loops and plates are positioned in the mould cavity, and concrete cast and vibrated by machines 8. Screeding is effected by a template run over the outer casing and of selected depth, and the inner casing 3 and concrete beam are lifted away by crane and placed on a hardening plate. The embedded plates (made of expanded polystyrene, steel or wood) are removed for forming apertures through the beam webs, which then receive transverse reinforcing rods and webs (see Fig. 2, not reproduced). Further recesses or concreting is effected. The beam is laid side-by-side with others to form a ceiling, and may have a curved longitudinal axis.

Title: Method of recovering copper from electrically insulated copper wire and a cupola furnace therefor

Filed: 1954-08-13
Abstract: 766,835. Recovering copper from insulated copper wire. REVERE COPPER & BRASS, Inc. Aug. 13, 1954, No. 23650/54. Class 82(1) [Also in Group XII] Copper wire having an insulating covering containing organic material is treated to recover the copper by destructively distilling the covering without ignition and then melting the copper of the wire which has become encrusted with carbonaceous residue from the distillation by burning the carbon in air, the supply of air being so regulated as to maintain a deoxidizing atmosphere with respect to the copper. In carrying out the method using a cupola furnace as shown in Fig. 1 an ignited coal or coke bed is formed in cupola 1 to the level 33, combustion air being supplied through tuyeres 17 from blower 13. Copper wire is charged to the furnace through charging opening 29 to a level 35. In the upper part of the charge the covering of the wire is destructively distilled by contact with hot non-oxidizing gases rising from the lower part. In the lower part of the charge the carbonaceous residue is burnt in combustion air from the tuyeres providing sufficient heat to melt the copper and to slag the inorganic mineral constituents of the covering, molten slag and copper percolating through the carbonaceous bed and being withdrawn separately from tapholes 27 and 25 respectively or together from a single taphole. Where the carbonaceous residue of distillation is more than necessary to provide heat for melting the copper the combustion air is sufficient to burn all the carbon and thus the height of the bed of carbon at the base of the furnace is maintained substantially constant. Combustible carbonaceous material such' as coke or anthracite, or solid meltable material such as solid slag may be added to the charge to form a layer over the carbon bed and to prevent finely divided carbon rising with the blast and elevating the combustion zone. The gaseous products from the furnace pass to a combustion chamber 3 in which they are burnt with air supplied through tuyeres 45 from blower 13.
