Title: Electrolytic process and apparatus for descaling and/or cleaning metals
IPC: C25F7/00
Filed: 1936-05-23
Abstract: 475,929. Electrolytic pickling. HINSLEY, J. F. May 23, 1936, No. 14651. [Class 41] A pair of electrodes F, G is moved over the surface of a metal plate D to be descaled and /or cleaned which thus constitutes an intermediate electrode, parts of the work thereby being subjected successively to anodic and cathodic treatment. The electrodes are suspended from a trolley H which is moved by an electric motor along a gantry I, the movement being automatically reversed and the gantry itself moved laterally each time the trolley meets stops J. When the arrangement is such that the edge portions of the work are subjected to the action of one electrode only, the current may be reversed when the trolley reverses. The electrodes may be separated by an insulating wall or may be arranged concentrically one within the other. Direct, alternating, or superimposed direct and alternating current may be employed. The work may be agitated to shake off scale. The electrodes may be caused to move over the surface of a curved article by means of insulated followers. An apparatus is described comprising an annular trough rotated about an inclined axis and arranged in such manner that that part occupying the lower position has its base horizontal and is filled with electrolyte, the treating electrodes being arranged to move over the work in this position. Loading and unloading of the work is effected in the uppermost position of the trough which is above the liquid level. A degreasing bach may consist of 6 oz. soda ash, 2¢ oz. caustic soda, 1¢ oz. sodium cyanide, 2 oz. tri-sodium phosphate, 1 oz. sodium silicate to 1 gallon of water. For descaling steel plates a bath of sulphuric acid of strength 4 per cent is employed. Specification 434,116 is referred to.

[Also in Division H4] In a method of producing, in a record medium, a modulated groove constituting a record of a signal, the signal is first modified to compensate for the difference in shape between the cutting and playback styli and the modified signal is then differentiated and utilized to control the velocity, of a cutter. Referring to Fig. 6, the input-signal is first fed to a circuit 21 which modifies it and then integrates it. The resulting signal V is then fed to a potential divider chain comprising resistors 22 ... 25 and to delay networks 29 ... 36 to produce a number of output signals which are then compared in a circuit 38, and the signal having the smallest value is fed to differentiator 41, the output from which controls the cutter.

Title: Improvements in and relating to salts of silanols as water-repellents
IPC: C04B41/49

Abstract: 736,561. Rendering masonry water-repellent. GENERAL ELECTRIC CO. May 27, 1953 [May 27, 1952], No. 14766/53. Class 140. Masonry containing calcium compounds and substantially free from silicon compounds is treated with an aqueous solution of a watersoluble alkali metal salt of a hydrocarbon substituted silanetriol and dried to convert the salt to a polysiloxane. The salts may be prepared by hydrolysing derivatives of a monohydro-carbon substituted silane containing three hydrolysable radicals (halogen atoms, alkoxy or amino radicals) and dissolving the hydrolysis products in aqueous alkali-metal hydroxide. The hydrocarbon substituent may be alkyl (e.g. methyl, ethyl, propyl, isopropyl, butyl, hexyl, decyl), aryl (phenyl, naphthyl, biphenyl), aralkyl (benzyl, phenylethyl), or alkaryl (tolyl, xylyl). The masonry may be sprayed, dipped, brushed, or otherwise coated with the aqueous solution of the salt and allowed to dry, the carbon dioxide in the air effecting conversion of the salt to the waterrepellent composition. Specified compositions include aqueous solutions of alkali metal salts of methylsilane triol, ethylsilane triol, phenyl-, benzyl- and tolylsilane triols. The treating solution may also contain alkali metal salts of diorgano silane diols or their polysiloxane condensation products. Comparative tests on limestone, gypsum and concrete treated with a solution of the sodium salt of methylsilane triol are reported in an example. Specifications 572,740 and 621,970 are referred to.

[A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 28, 1936.] [Class 4] An airship is provided with a nacelle having an airscrew adapted to function as a sustaining screw mounted beneath it and arranged so that its axis can be inclined in any direction to a normal vertical position. An airscrew 38, Figs. 2 and 3, is arranged forward of the centre of gravity of the aircraft which in turn is forward of the centre of static lift. The axle 37 of the airscrew may be tilted laterally to produce a lateral component of airscrew thrust Sy so directed as to convert the rotation of the hull due to the airscrew torque reaction into a lateral drift of low velocity. The static lift of the craft may be less than the weight. An engine driving a tractor airscrew may be provided, and the tilting airscrew may be mounted in front of the alighting gear as shown in Fig. 5, or between the fore-and-aft elements thereof, Fig. 8. The mounting of the tilting screw and engine is shown in front and side elevation in Figs. 6 and 7 respectively. A crown 32 is journalled for rotation about a vertical axis X-X in a bearing 33 fixed to nacelle 7. An extension 34 of crown 32 carries horizontal pivots of an engine 37 driving the screw 38. Conical struts 39 secured to crown 32 carry a wormwheel meshing with a worm which may be remotely controlled by chain gear, Fig. 8 ; alternatively rotation of crown 32 may be directly controlled. Rotation of engine 37 on pivots 35 is effected by a shaft 46 connected at one end by a universal joint to the shaft of a worm 48 meshed with a worm 49 fast on the engine mounting, and at the other end by a similar joint to a driving shaft 42 carrying a worm wheel 41. A ball and socket mounting for the engine may be substituted for the pivotal mounting shown.
