Abstract: 578,364. Making radiators &c. COLTMAN, J. L., PARKER, G., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 18, 1944, No. 25344. [Classes 83 (ii) and 83 (iv)] Soldering.-Articles formed of or coated with alloys comprising essentially copper and zinc with a major proportion of copper are brazed by coating the parts with a thin layer of silver and then assembling and heating in an inert or reducing atmosphere to a temperature between 680 and 780‹ C. so that the ternary copper-zinc-silver eutectic is formed and bonds the parts together. The parts may be held in a jig or by a ceramic tile superimposed thereon. Brazing may be effected in an atmosphere of cracked and burnt ammonia in a furnace controlled automatically at a temperature of 700‹ C. The thickness of silver may be 0.00015 to 0.00025" and may be applied by electro deposition or by placing it as a layer on a billet and rolling down to required thickness.

Title: Improvements in the gasifying of heavy oils
IPC: C10G9/38
Filed: 1928-09-04
Abstract: 296,785. Chilowsky, C. Sept. 8, 1927, [Convention date]. Oil gas.-In the gasification of heavy oils by heat derived from partial combustion with air, the air is heated to 500-900‹C. The air to which steam may be added is admitted through a pipe 12 to a jacket 9 formed by metal cylinders 8, 10. A helix 15 provides a conduit of small crosssection which terminates in a pipe 13 leading to the oil sprayer 1. Partial combustion of the oil occurs in the generator 2, resulting gases passing through a catalyst 3 and imparting heat to a refractory member 6. An alternative air passage may be provided by horizontal rings in the jacket each having a gap arranged on alternate sides of a vertical strip. The cylinders 8, 10 may in another form provide a very narrow passage, being merely spaced from one another by wires or gauze. Radial flanges may extend from the cylinder 8 into both gas and air conduits or the heat exchanging wall 8 may be corrugated and in contact with both the member 6 and cylinder 10. For imparting temperatures from 800-900‹C the wall 8 may consist of a thick cylinder of non-rusting steel or alloy in which are pressed or cut narrow grooves providing flanges in contact with the members 6, 10. The upper part only of the air conduit may comprise such grooves, the lower part consisting of a helical passage. If the oil gas supplies an internal combustion engine, the exhaust gases may be used to heat the air supplied to the generator and to evaporate water for the steam supply. The air admitted to a tube 41 mixed with water entering through holes 42 passes as a thin layer through a double wall 39 of the exhaust conduit and is further heated in jackets 48, 35 surrounding the exhaust pipe. The air may be subsequently heated in a jacket 9 of the generator. The Specification as open to inspection under Sect. 91 (3) (a) describes the heating of the air and steam to 1000‹C and over. This subjectmatter does not appear in the Specification as accepted.
