Abstract: In incandescent lamps having a pinched seal surrounding an exhaust tube, it is customary to heat the exhaust tube in situ in the surrounding glass envelope and then to pinch the softened envelope on to the tube. This involves complex heating arrangements. According to the method of invention the envelope (1) and exhaust tube (2) are heated separately by respective burner assemblies (7, 8) and are moved into their relative positions, and the pinch formed, when each has reached the required temperature. This provides a simpler and more rapid manufacturing operation. <IMAGE>

Title: Cutting and folding sheets
IPC: B41F13/60

Abstract: A folding mechanism adapted for cutting printed sheets from a web, includes a collecting cylinder 1 with radially movable folding blades e.g. 5, cutting grooves e.g. 11, 13 and grippers e.g. spikes 9, 11, a cutting cylinder 3 with cutting knives 17, 19, and a receiving cylinder not shown. Two sheets are collected on each gripper and transferred to the receiving cylinder. To avoid the end of the first collected sheet 21 being trimmed a second time when the second, superposed sheet 23 is cut from the web, the folding blade 5 underneath the sheets is moved radially outwards to displace the end of the first sheet away from the cutting groove 15. Contact between a projecting folding blade and the cutting cylinder is avoided by providing flats 27, 29 on the latter or by not moving the blade out until after it has passed the nip. <IMAGE>

Title: Process for recovering vanadium values from acidic chloride solutions
IPC: C22B34/22
Filed: 1979-04-04
Abstract: The present invention provides a method for recovering vanadium from ferruginous chloride solutions by liquid-liquid extraction (or liquid ion exchange). Such chloride solutions are obtained in the extraction of vanadium from vanadiferous residues arising from the chlorination of titaniferous ores and in the extraction of vanadium from vanadiferous minerals. These solutions contain chlorides of vanadium, aluminium, iron, manganese and chromium. The method comprises adding sulfate ions to the chloride solution and recovering the vanadium by liquid-liquid extraction. By adjusting the sulfate-additive in relation to the concentrations of vanadium, iron and chloride in the solution vanadium can be extracted substantially free from iron.
