Title: Production of fresh water from sea water
IPC: C02F1/00
Filed: 1943-06-16
Abstract: 567,529. Purifying water. FRISCH, H. R. June 16, 1943, No. 9609. [Class 46] A potable water is obtained from sea water by treatment with lead fluoride and a trivalent fluoride, selected from ferric, aluminium, titanium, or zirconium fluorides, in the molar ratio of 40/11. The calcium and magnesium sulphates in the sea water are precipitated as lead sulphate, magnesium fluoride, and calcium fluoride. The magnesium and sodium chlorides in the sea water give a precipitate of magnesium fluoride, while the sodium fluoride which is formed reacts with the trivalent fluoride, such as aluminium fluoride, to give a precipitate of a cryolite, such as Na3AlF6. The traces of lead fluorochloride formed can be removed by treating with magnesium phosphate, to precipitate lead phosphate and magnesium fluoride, or by adding a small amount of sea water.

Title: Improvements in or relating to the manufacture of printed electric circuits
IPC: H01B1/00
Filed: 1958-03-27
Abstract: 842,789. Printed circuits. GENERAL ELECTRIC CO. Ltd., and MILLS, R. March 24, 1959 [March 27, 1958], No. 9927/58. Class 37. A method of manufacturing a printed circuit from an insulating base, having a conductive layer on one or both sides, comprises covering parts of the layer with a resist, electro-plating a first metal on to at least some of the exposed areas and then electro-plating a second metal on to at least some, but not all, of the exposed areas. The resist is then removed, and the unplated parts removed by etching. In the embodiment described, a printed circuit panel comprising a rectangular phenolic resin board to one surface, at least, of which is bonded a layer of copper foil, has a plating resist formed on the foil by a silk screen or a photographic process to leave exposed the required conductive pattern. The conductive pattern includes a number of contact areas adjacent one edge of the board, for making contact with a bank of contact members in a larger assembly on which the panel is mounted. A layer of silver is plated on to the exposed circuit pattern by immersing the board in an electro-plating bath, and although the contact areas are normally included in the parts plated they may be if desired covered so as not to be plated or the board may be so arranged in the bath they they are above the surface of the plating solution. The pattern is then painted with more resist, e.g. cellulosic enamel, so that only the contact areas are exposed and the board then placed in a nickel-tin plating bath, and a coating of nickel-tin (65 % tin to 35 % nickel by weight) formed on the contact areas. The resist is then removed and the unwanted parts of the copper foil etched away. The circuit may then be completed by forming any required holes in the panel and adding any required conventional component.

Race games, mechanical.-A pedal-actuated device for use in competitions between several players or for use as a training device for track racing, and of the kind comprising a miniature race track round which a number of models of small cycles or other devices are carried, each being driven individually by gearing or other articulation from one of a series of pedal-actuated cycles or the like, is characterized by the provision of means for automatically and simultaneously disengaging all the models from their driving connections at the moment when the first model has reached the winning post. The cycles 2 of the competitors are connected by chain gearing to a series of sprocket wheels 23 each gearing with an endless chain 24 to which a racing model 3 is attached. The gear ratios are arranged so that all the models complete a circuit of the track for the same number of revolutions of the competitors' cycle pedals. When the leading model has reached the winning post 36, one of a series of electricall contacts 37 is engaged by the model, and all the sprocket wheels 23 are automatically thrown out of gear with the chains 24, thus arresting all the models. Mechanical devices may be used instead of electrical. To permit the disengagement of the sprocket wheels 23 universal couplings are introduced into their driving shafts and the bearings for the sprocket ends of the driving shafts are pivoted, so that the wheels may be drawn out of mesh with the chains. The track is preferably formed as a series of channels made up of angle irons 26, Fig. 5, bent to the curva.- ture of the track. The angle irons form guides for the chains 24, and blocks 25 keep the chains in engagement with the sprocket wheels 23. The model 3 is connected to the chain 24 by a stem 33 provided with a roller 29. Instead of sprocket wheels 23 friction rollers may be used. An additional series of sprocket wheels or friction rollers operated by hand may be provided for returning the models after a race. The parts may be proportioned so that each racing model completes one circuit, whilst the periphery of the corresponding cycle wheel travels one mile or other definite distance. A timing clock started and stopped automatically at the beginning and finish of the race may be provided. The identification mark of the winner may be automatically indicated on a board.
