Abstract: A flight of steps, stairs and the like heated by means of a heating medium passing through a pipe located within the steps, stairs etc. The pipe is located totally within the confines of the step structure and extends in a tortuous path generally longitudinally of the flight of steps. The pipe is permanently pre-shaped so as to present interconnected, generally arcuate looped portions and can be made to conform to the step configuration substantially solely by twisting the pipe at selected regions along its length.

Abstract: A device and method for recovering metal accompanying slag skimmed from the surface of a bath of molten metal are described. The device has the form of a trough provided with a perforated bottom member, which is intended to be located at substantially the same level as the surface of the molten metal in the furnace. When using the device, slag is charged thereto and heated to a temperature which is at least equal to the temperature of the metal being treated. Whereupon any metal in the slag melts and runs down through the perforated bottom member of the device in the molten metal bath. Residual components of the slag are then removed from the device.

Abstract: A method and apparatus for manufacturing elongate heat-exchanger blanks composed of a basic substrate profile having at least one length of corrugated metal foil strip mechanically bonded thereto. A basic elongate profile string is advanced at a predetermined speed along a fixed path and at least one strip corrugating device is arranged to produce a continuous length of corrugated strip and to feed the strip into the path of the basic profile via a number of corrugated strip cutting and feed means. These latter means operate cyclically to cut the strip at predetermined intervals and to join the cut lengths of strip to the basic profile string in spaced relationship at a frequency corresponding to the intervals.

Abstract: There is provided a method of charging an electrolyte bath containing aluminum oxide for the manufacture of aluminum by smelt electrolysis, with fresh supplies of aluminum oxide as the electrolyte is depleted thereof. A pre-determined store of aluminum oxide is constantly maintained on the crust covering the bath. This crust is then partially broken by raising and lowering the anode at predetermined intervals during the electrolysis to permit the oxide resting on the crust to enter the bath, thereby to increase the aluminium oxide content of said bath.

Abstract: A method and apparatus for producing highly effective heat exchanger elements of the type which comprise corrugated surface enlarging members of strip material fixed to thin-walled substrates. The strip material, which can be either precorrugated or corrugated synchronously with the heat-exchanger element manufacturing process and which has a thickness of from 50-10 Mu m, is advanced concurrently with a substrate material to a station at which the strip is lightly held in firm abutment with the substrate material by means of an impringing stream of gaseous medium and simultaneously metallurgically bonded to the substrate. The composite product is then cut into lengths to form finished heat exchanger elements.
