Title: Improvements in or relating to electrolytic processes for the manufacture of magnesium
IPC: C25C3/04
Filed: 1936-12-03
Abstract: 482,678. Electrolytic production of magnesium. GARDNER, D. Dec. 3, 1936, No. 33167. [Class 41] Magnesium is obtained by electrolyzing anhydrous magnesium sulphide dissolved in a fused normal anhydrous fluoride or mixture of anhydrous fluorides, the melting point of which fluoride or mixture of fluorides is substantially below about 1100‹ C., preferably about 1000‹ C., in an atmosphere of a reducing and /or inert gas such as hydrogen or argon, at ordinary or reduced pressure, and in absence of moisture, nitrogen, and oxygen or oxygen-containing gases. The melt may consist of magnesium fluoride and sodium or potassium fluoride or of cryolite. The electrodes may be of carbon, and the chamber should be lined with a material such as graphite, carborundum or petroleum coke. Any magnesium sulphide present in the product may be removed by distillation, and the process may be continuous or intermittent. Specification 465,421, [Group II], is referred to.

Title: Improvements in and relating to cooking stoves
IPC: F24C15/10
Filed: 1932-11-28
Abstract: 410,858. Cooking-apparatus. PERKS, T. E., and ROSS, C. E., c/o Still & Son, Ltd., Charles Street, Hatton Garden, London. Nov. 28, 1932, No. 33648. [Class 28 (i).] A hot-plate or grid on which an article, e.g. a pancake, is cooked, is arranged to be operated so that it tosses the article freely into the air and catches it again, reverse way up, as it falls. As shown, the cooking plate 1 is pivoted at 8 to a fixed structure, and is connected by a link 3 to a spring 4 which is anchored at 5. To toss the pancake, the handle 2 is raised and the plate 1 is thereby slightly depressed and the spring 4 is tensioned. The link is retained in this displaced position by the engagement of the spring controlled trigger 10 with the lower notch 12 in the link 3, the upper notch 11 being engaged in the normal cooking position. When the trigger 10 is released, the spring rapidly rotates the plate 1 in a clockwise direction and tosses the pancake. The height of the pivot 8 above the plate 1 may be adjustable. The plate may be operated by electromagnetic means, and returned to the cooking position by springs. A heater may be arranged above the plate to radiate heat downwardly to facilitate the cooking of the pancake, or, at least, to seal the upper surface prior to the first tossing. The batter may be supplied by hand, or by a mechanical pump or bucket, and a removable ring may limit the flow of batter over the plate. The tossing motion may be utilized to grease the cooking plate, 'a small quantity of oil being released from a reservoir when the plate is operated. A grid, having a tossing-means, may be slightly immersed in cooking oil heated in any manner. The plate or grid may be enclosed in a glazed cabinet for shop-window exhibition purposes, the cabinet having compartments for the display of the ingredients used in the making of the article, and for the display of the cooked articles. The cooking odours may be withdrawn from the cabinet and distributed to attract the attention of passers-by. For this purpose, a metal hood, or hoods, are connected to an air-pump from which the odour-laden air is delivered by a pipe, or pipes, suitably concealed, to the outside of the shop.

Abstract: 356,997. Peeling and pulping fruit. ROWAN, W. W., Prome, Glenpatriok Road, Elderslie, Renfrewshire. Nov. 10, 1930, No. 33760. [Class 28 (ii).] In a machine for removing the rind or skin from fruit, and pulping the fruit, e.g. for the manufacture of marmalade, the fruit is pushed on to four vertically arranged knives and is thereby practically quartered, the quarters falling on to shoots which lead them to pulping rollers associated with peeling knives. As shown, the oranges are placed in apertures in an endless belt S which positions each one beneath a pusher I, adjustably carried on a reciprocating crosshead G, which pushes them between four triangular knives J which completely sever the orange into two halves which are themselves nearly subdivided into quarters. The two halves move over the shoots O and are engaged by the spiked rollers L which press them against rollers M having recesses and circumferential grooves to receive and hold the pulp whilst the peel is stripped off by knives N and is directed by shoots P to discharge grids Q. The pulp is ejected from the grooves of the rollers M by scrapers M<3>. When harder fruit than usual is being treated, the action of the rollers L is assisted by cranked members i on shafts k which are oscillated by the engagement of pinions thereon with racks connected to rods p, returned by springs t, and actuated by a cam on the shaft c engaging a protuberance on the lever q.

Title: Improvements in or relating to the recovery of silver from solutions of silver compounds
Inventor: COOTE JACK HOWARD

Filed: 1956-11-07
Abstract: 817,912. Electrolytic apparatus. ILFORD Ltd. Nov. 6, 1957 [Nov. 7, 1956], No. 33965/56. Class 41. An apparatus for recovering silver from solutions of silver salts comprises a shaft 1, means, e.g. an electric motor 8, for rotating the shaft 1 about its axis, at least one helically wound metal fin 12 mounted axially on the shaft 1 and adapted to be connected to form the cathode of an electrolytic cell, and an electrode element, e.g. a plurality of carbon rods, spaced from the fin 12 and adapted to be connected to form the anode of the cell. Each fin 12, which is of stainless steel, makes one circuit of an element 10 which is suitably grooved at 11, the shaft 1 screwing into the element 10. Electrical connection is by a bushing 3 and a collar 5 to the shaft, all parts of the cathode unit except the fins 12 having an insulating surface. In an example, a bath containing 5 to 10 gms. per litre of silver is electrolysed employing a current of up to 5 amps., e.g. 2 amps. at 1.5 volts, the cathode being rotated at 100 r.p.m. Silver is removed from the fins 12 by flexing them. The electric circuits to the motor 8 and to the cell are preferably interconnected to prevent electrolysis taking place if the motor 8 stops, the stirring action of the cathode preventing sulphiding where a thiosulphate bath is employed. One fin only may be employed, and it may constitute less than a complete turn, and where more than one fin is employed, they may be separated by collars on the shaft. The anode rods may surround the cathode and both anodes and cathode be supported from a common framework.
