[Also in Division F1] A telemotor system used for simultaneously changing the swash plate angles of the pump and motor units of an hydrostatic transmission, comprises swash plate adjusting slave cylinder units 32, 34 each movable by a respective master unit 36, 46, the pistons 40, 50 thereof being arranged to move in a predetermined out of phase relationship. Each piston 40, 50 has a rod 78, 79 connected by a respective link 110, 111 to an individual cam plate 112, 114, both rotatable about a pivot 115. The cam plates have differently shaped cam slots 116, (118) in which slide a cam roller 122 carried by a crank 124 rotated by a handle (not shown). Thus, rotation of the handle causes the roller 122 to ride in the slots 116, (118) thereby imparting out of phase rotation to the cam plates and consequential out of phase movement of the pistons 40, 50. As shown, the crank 124 is held in a neutral position by a pawl 128 urged by a spring 129 to engage a detent notch 127. In the neutral position opposite sides of the pistons are in communication through cylinder ports 85 and a chamber 72 surrounding the cylinders 32, 34, whereby springs 33 can move the slave pistons 30, 35 to their neutral positions thus re-phasing the pistons 30, 35, 40, 50. A spring loaded plunger 90 is provided for pressurizing a chamber 84 connected by a non-return valve to the chamber 72. The chamber 84 is filled by withdrawing the plunger 90 to suck hydraulic fluid from a reservoir 68 through a valve (not shown). If fluid in the lines 37, 38, 41, 42 between the slave and master units exceeds a predetermined pressure, due to say expansion, pressure is relieved through a valve 60 to the chamber 84.

Title: Improvements in or relating to the production of nickel by electrolytic deposition from nickel salt solutions
IPC: C25C1/08
Filed: 1933-08-18
Abstract: 420,248. Electrodeposition of nickel. FALCONBRIDGE NIKKELVERK AKTIESELSKAP, Kristianssand, Norway. Aug. 18, 1933, No. 23091. Convention date, Sept. 3, 1932. [Class 41] Nickel of high purity is obtained by first preparing a nickel salt solution which may contain dissolved iron salts together with impurities such as arsenic, copper, and lead, but which is of a degree of purity generally considered sufficient for the electrodeposition of nickel, subsequently depositing nickel from this solution in two or more steps, in the first step or steps of which a comparatively small amount of nickel, for example, 3 to 5 per cent of the total quantity, is deposited, this initial deposit containing most of the impurities in the original solution, and thereafter depositing a comparatively pure nickel from the solution which remains. The preparatory treatment for the removal of the impurities may be effected either with soluble nickel anodes substantially free from foreign metals, or with impure nickel anodes in a cell having the anode compartments separated from the cathode compartments by Hybinette bags. When using soluble nickel anodes, for example, anodes containing nickel oxide or carbon, the pH value of the electrolyte may be adjusted by varying the current density and total current employed in proportion to the flow of solution. The electrolyte may be brought into intimate contact with the cathodes by violent agitation with air and by employing a large cathode surface in relation to the quantity of electrolyte flowing through the tanks. The current density and the current employed may be so regulated as to permit neutralization of the electrolyte to such a degree as to allow practically all the iron to be precipitated on subsequent oxidation and hydrolysis. The preparatory treatment for removal of the impurities may be carried out in two or more steps, in the first of which an impure nickel is deposited, and in the succeeding step or steps a comparatively pure nickel enriched in cobalt. Two or more preparatory treatments may also be employed, resulting, in the first preparatory treatment, in the production of an impure nickel enriched in cobalt, and in the succeeding treatment or treatments in a comparatively pure nickel also enriched in cobalt. Examples are given. Specification 372,958 is referred to. The Specification as open to inspection under Sect. 91 comprises also diagrams showing arrangements of cells and electrodes for carrying out the process, and also a flow sheet illustrating a cyclic method which can be employed when iron is to be precipitated from the solution. This subject-matter does not appear in the Specification as accepted.
