Title: Process of fusion electrolysis for metal production
IPC: C25C3/00
Filed: 1960-09-07
Abstract: In obtaining the metals Ti, Zr, Mg, Al, B, Be, Th, and U by fusion electrolysis of their salts in the presence of alkali metal halides, there is added a compound containing the desired metal halogen, hydrogen, and nitrogen, preferably made by reacting NH3 with the metal halide, e.g. a loose compound of formula (NH3)xTiCl4. Preferably this is heated under reduced pressure in an atmosphere of NH3 at 1000  DEG C., the product being then stable to oxygen and water.  Preferably the halogen present is the same as in the fused metal halide being reduced, but a different metal may be used in the added compound to form alloys, e.g. Zr/Ti. The electrodes used may be of the desired metal, carbon, Mn3O4 or chromium oxide.  The added compound lowers the fusion point and reduces the formation of "smoke".

Title: Improvements in or relating to Controllers for Sequentially Operating Fluid Powered Devices
Inventor: PETTERSSON ANDERS GUSTAV HUGO
IPC: F15B13/07
Filed: 1968-07-01
Abstract: 1,179,645. Sequentially operating fluid powered devices. AIRMATIC A.B. July 1, 1968, No.31346/68. Heading F1P. An odd number of differential area pistons 4, 9, 16 are movable in respective piston chambers 40, 41, 42 by fluid-pressure acting thereon, the movements taking place in a predetermined sequence thereby to cause consecutive pressurization of bores 6, 13, 20 leading to devices to be operated in sequence. The piston chambers 40, 41, 42 are provided in a housing 50 having an inlet 1 communicating directly with the chambers at their lower small diameter ends. When the pistons are in their bottom positions the bores 6, 13, 20 are connected by annular compartments F in the pistons to respective throttled exhaust ports 5, 12, 19. The piston 4 is shown in its operative position wherein fluid from the inlet 1 is admitted via an annular groove 43 to the bore 6. After the device connected to the bore 6 has operated, pressure rises in the bore 6 and thus also a duct 10 leading to the piston chamber 41 at its large diameter end B above a floating piston 8. This pressure rise moves the piston 9 to its bottom position shown, and holds it there. With the piston 9 in its bottom position, ducts 17 and 18 exhaust through port 12 at a rate determined by the throttle connected thereto. The exhaustion of duct 17 collapses the pressure acting on the large end B of piston 16 which thereby moves to its upper operative position in which the bore 20 is pressurized. The subsequent pressure rise in bore 20 when the connected device has operated pressurizes a duct 2 connected to the upper chamber end of the piston 4. This piston is thus moved to its bottom piston wherein the bore 6 is exhausted, together with the duct 10, at a controlled rate. Pressurization of bore 13 and exhaustion of bore 20 occur in a similar way to complete the cycle, whereafter the cycle is repeated.

Title: Improvements in apparatus for automatically lighting electric lamps at any predetermined time
IPC: G04C23/16
Filed: 1926-12-10
Abstract: 262,807. Mercier, L., and Borgne, V. Dec. 11, 1925, [Convention date]. Lighting systems. - The lamps R of a motor vehicle are automatically lighted at a predetermined time by a, clockwork time switch which closes at L the circuit to an electromagnet P which then attracts its armature into engagement with contacts 0, I thereby closing a maintaining circuit for the electromagnet and connecting the accumulator Q with the lamps. The electromagnetic switch, Fig. 8, is combined in one structure, with a hand-operated switch comprising an insulating sector s carrying two contact brushes X, which serve to connect contact segments a, b with contacts c, d respectively. When the time switch is not required to be used, the contact brushes X are moved into their other position in which they rest on dummy contacts. The time switch, Fig. 3, may comprise the ordinary dashboard clock modified by the provision of a clockwork-driven cam wheel E against the edge of which bears a finger D or a member I slidable in the spindle A under the influence of a spring G. The finger D is set to a predetermined position by rotating the spindle A by means of a pointer B. At the predetermined time a notch in the cam wheel E comes opposite the finger D and the spring G, forcing the member I to the right, brings a contact ring J into engagement with a contact L. As the clockwork continues to revolve, the finger D rides up a sloping surface of the cam E and the contacts J, L separate, but the maintaining circuit through the electromagnet causes the lamps to remain lit.

Abstract: 190,124. Rushmore, S. W. Dec. 6, 1921, [Convention date]. Radiators, motor-car and like. - In cooling systems for internal-combustion engines for vehicles wherein the water in the cylinder jacket is maintained in the neighbourhood of the boiling point and the steam generated is condensed in a surface condenser having the form of a radiator, as described in Specification 177,482, [Class 7 (ii), Internal-combustion engines, Arrangement &c. of], the condenser is modified to prevent a down flow of steam and air in the cold central portion due to insufficient condensation in the less cold side or back portions of the condenser. To this end the side passages or tubes of the condenser may be lengthened or made of smaller cross-section than those of the central portion, or may be provided with constrictions tending to create a slight back pressure in the side portions. In the example shown in Fig. 1, the side tubes are fitted at the top with plugs 9 having vents 10. The central tubes may also have similar plugs. The upper steam and air space 5 may be cooled by open-ended cross tubes 12 and radiating fins 11. The steam tubes 4 have radiating plates 6 fitted to them. The hot water enters the lower chamber 1 by a pipe 2 and is withdrawn through a pipe 3 by a pump. In another form, the tubes may be covered at the top by one or more plates provided with a vent or vents common to a group of tubes. The usual overflow pipe 13 in the upper space 5 may have its end turned downwards so as to discharge any layers of air below the steam collected in the top of the space. A honeycomb type of condenser, Fig. 7, may have baffles 19<a> with vents 10<c> between the sides and the centre of the top chamber. In some cases a baffling effect in the side chambers may be obtained by loosely packing mineral wool in the sides of the upper chamber 5. The vents in the plates covering groups of tubes may be fitted with ball valves made of bakelite, the central vents having valves opening outwards and the others having inwardly opening valves. The vents in the plates may be shaped so as to lead condensate from the upper chamber down into the tubes.

Title: Electrolytic iron
IPC: C25C1/06
Filed: 1921-12-22
Abstract: 194,639. Eustis, F. A. Dec. 22, 1921. Iron salts.-In order to produce an electrolyte for the deposition of the metal, iron oxide, which may be in the form of a natural or roasted ore, is dissolved by a weakly-acid solution of a ferrous salt, such as the chloride or sulphate; this solution is said to be an efficient solvent for ferric oxide. To obtain the solvent, a ferric solution, which may be drawn from the anode compartment of the depositing vat A, is reduced by an agency which simultaneously produces free acid; for instance, reduction may be effected by electrolysis in a separate vat, or by treatment with sulphur dioxide in a tower L. The gas may be generated by roasting the ore in a furnace K, from which the ore is delivered into a lixiviating tank B. A suitable temperature for lixiviation is 70‹ C. The ore should be finely-divided, and the counter-current principle may be utilized in the lixiviating tank. As the ore solution contains ferric salts, the greater part, after filtration, is returned to the reducing tower L. The rest of the solution, optionally after treatment with scrap iron, is neutralized and freed from ferric salts by limestone in a tank D. It may then be heated nearly to the boiling-point before entering the cathode compartment of the depositing vat A. Specifications 194,638 and 196,334 are referred to.
