Title: Improvements in or relating to the formation of metal coatings by electrophoretic deposition
Inventor: JACKSON ALBERT EDWARD
IPC: C25D13/16
Filed: 1961-11-15
Abstract: In forming metal coatings on metal strip by electrophoretically depositing the coating metal from a suspension of finely divided coating metal, drying the coated strip to remove entrained electrophoresis medium, rolling the coated strip to compact the deposit and then heating the strip to obtain a tightly bonded coating, the strip is passed in a straight pass from the electrophoresis bath through the drying station to the compacting rolls without engaging any intermediate roll.  Preferably the pressure applied by the compacting rolls is 1.5-10 tons per inch width of the coated strip. In order to simplify the processing line, a light weight mill applying a pressure of 0.5-1 ton per inch strip width may be arranged vertically above the bath and drying station, this effecting sufficient compaction of the coating to allow the strip to be passed over a roller to change the strip direction without damage to the coating, whereafter the compaction of the coating is completed in a second mill applying a pressure of 1.5-10 tons per inch strip width.  Cleaning rolls covered with soft fibrous material and doctor knives may be provided to prevent coating build-up on the compaction rolls. Drying of the coating is effected by air knives across the strip width impinging at an acute angle, e.g. 30 degrees, against the direction of the strip travel, thereby reducing the bath drag-out loss, together with radiant heaters.  The electrophoresis bath used for coating steel strip with aluminium comprises 20% aqueous methylated spirit containing 0.5 millimoles/litre aluminium nitrate in which aluminium powder is dispersed and a current density of 10 A.S.F. is employed.  The metal particles are maintained in suspension by passing the suspension in at the bottom of the tank on opposite sides of the strip and out at the top by an overflow, the tank being only of sufficient size to accommodate the strip and anodes.  Solvent recovery from the drying station is effected, the condensate being returned to the cell.  The compacted strip is preferably consolidated by heating after coiling. Specification 884,797 is referred to.

Title: A process for the production of alkali metal and alkaline earth metal borohydrides
IPC: C01B6/00
Filed: 1957-03-28
Abstract: Alkali or alkaline earth metal borohydrides are prepared by reacting an alkali or alkaline earth metal hydrocarbon with a substituted diborane containing up to 4 hydrocarbon radicals, or a substituted borine BRR12 where, R is a hydrocarbon radical and R1 is hydrocarbon or H.  Where the substituted borine contains no H, then H2 must be present for reaction. Reaction may be effected in inert organic liquid aliphatic or aromatic hydrocarbons, ethers, or tertiary amines, e.g. hexane, benzene, perhydrocumene, tetrahydrofuran, or diglycol dimethyl-or triglycol trimethylethers.  If reactants and products are insoluble in the liquid, reaction may be effected with simultaneous comminution, e.g. in a ball mill.  Where ethers are used the borohydride is formed as an etherate, and with tertiary amines the reaction may be under pressure at above 160 DEG  C. Reaction may be in inert gas, e.g. N2 or A, with heat, with, or without, distilling or filtering off the boron hydrocarbon also formed, and the substituted borine, or diborane, should be in excess.  The boron trihydrocarbons formed may be hydrogenated to borines as in Specification 854,919.  Colloidal B formed in the p  reaction may be washed out with solvent.  In examples:- (1) Mg(CH3)2 is reacted with B(C2H5)3 an H2; and (2) Li C6H5 is reacted with B(n-C4H9)3 and H2.

Title: Model sailing vessels
Inventor: SMITH GEOFFREY TURBERVILLE
IPC: A63H30/02
Filed: 1967-09-12
Abstract: 1,207,495. Steering means for toys. G. T. SMITH. 10 Dec., 1968 [12 Sept., 1967], No. 41498/67. Heading A6S. [Also in Division G1] A steerable, power driven model sailing vessel has photoelectric means for detecting radiant energy in a collimated 'beam simulating the wind, and controlling the speed of the vessel in accordance with its angular relationship with the radiant energy. The mast of the vessel, which has a hollow base, carries the photoelectric control device 25 and is pivotable in association with pivoting of drive wheel 12, mounted in its motor 21, by means of link work 18, 19 and a Bowden cable 16. The vessel sits on the drive wheel, pivotable idler wheel 13 and one of idler wheels 14 or 15, all the idler wheels being in a common plane higher than the drive wheel. In use, when the vessel is not sailing into the wind (i.e the photocell is not illuminated by light from the fixed direction collimated beam), it travels at full speed ahead. When it is steered, by cable 16 pivoting the drive wheel, into the wind, the photocell is illuminated and either the speed is reduced, or, as in the embodiment described, a relay is actuated causing reversal of the motor and thus of the vessel. To prevent oscillations of the vessel when changing from one tack to another, limit switches are provided associated with the angula.r orientation of the drive wheel. In this way reversal of the motor is prevented at these points so that the change can be accomplished. One or more of the idler or drive wheels may be eccentric to provide a pitching action. The device 25 may be mounted on the hull. The speed of the vessel may be controlled by the operator. Radio control, instead of mechanical, may be used. The "wind" may be provided by a number of lamps suitably shielded, modulated at a frequency different from mains, the photocell output being filtered at this frequency.

Filed: 1959-12-07
Abstract: 925,079. Electrolysing brine. RUHRCHEMIE A.G. and STEINKOHLEN-ELEKTRIZITAET A.G. Dec. 7, 1959 [Dec. 22, 1958], No. 41528/59. Class 41. In the electrolysis of brine using a mercury cathode, which is then decomposed electrolytically in the presence of water to form NaOH, the two electrolysis cells are connected in series and a counter-electrode is used in the second stage to balance the H potential, the electrode being made of Raney-type double skeleton material. An additional voltage is applied to the counterelectrode from an external source in parallel with one of the cells, and the negative pole connected to the mercury amalgam cathode. A circuit is shown in Fig. 1A, where C and Hg are the electrodes in the brine cell, b is counterelectrode in the decomposer cell with NaHg as amalgam electrode, Uz is an additional voltage source supplying current through an adjustable resistance W, whereby current in the decomposer compartment is adjusted to that of the main brine cell. This provides for the larger energy consumption in the brine cell. The double skeleton electrode is prepared by using a carrier material, e.g. iron or nickel in powder form and adding a powdered Raney alloy, e.g. A1 and/or Zn and/or Mg, and nickel, and sintering the mixture, after which the product is leached with NaOH. The product is formed of two interpenetrating bonded skeletons, one of carrier metal particles, and the other of microporous Raney metal. Small amounts of platinum group metals improve the efficiency of the electrode, and a little added MgO prevents recrystallization of the metal. The powdered metals may be pressed on a metal gauze support before sintering. In an example, iron foil after etching is used as a support to which a mixture in powder form of MgO, Ni/Al alloy, and Ni, all of particle size 75-100 Á, is applied, and pressed at 400 C. The alloy contains 48 parts Ni, 4 of MgO, and 48 of Al. A coating of 0.25 mm. thick is applied, and further treated to form the double skeleton. A test is described showing the improved voltage characteristics. Specifications 806,644 and 825,445 are referred to.
