Patent GB-863286-A (GB)
Title: Improvements in or relating to processes of separating palladium from metals of the platinum group
IPC: C01G55/00
Filed: 1958-11-17
Abstract: Palladium is separated from metals of the platinum group, particularly platinum, rhodium and iridium from an aqueous solution containing at least one metal of the platinum group, by maintaining the aqueous solution in an acid condition by the presence therein of at least one strong acid, and providing and maintaining a sulphur dioxide content in the aqueous solution of at least 0.3 grams per litre, and thereafter adding at least the stoichiometric amount of a water-soluble iodide to form PdI2 which is precipitated selectively and separated.  The initial solution should not normally contain hydrochloric acid with nitric acid but hydrochloric, nitric or sulphuric acids may be employed for acidification.  The precipitate of palladium iodide may be ignited and reduced to metal which is taken up in aqua regia leaving any rhodium or iridium undissolved and the resulting solution of chlorides of palladium with contaminant platinum is freed from nitric acid by evaporation and further addition of hydrochloric acid.  The solution so prepared is treated with sulphur dioxide in an amount of 0.3 to 4 grams per litre and the palladium precipitated as iodide as before.  The ratio of palladium to metals of the platinum group in the starting material as metals is preferably at least 1 to 1.  If the ratio is as low as for example 1 to 19, two redissolvings of the metal remaining after ignition of the precipitate and two reprecipitations will be necessary to separate the palladium.

Title: Improvements in electric time switches
Inventor: HORSTMANN BEVAN GRAHAM
IPC: G04F3/06
Filed: 1954-12-24
Abstract: 782,659. Time switches. HORSTMANN GEAR CO., Ltd. Dec. 28, 1955 [Dec. 24, 1954], No. 37371/54. Class 38 (5). A switch similar to that of Specification 774,186 has a knob 35 attached to a spindle 17 carrying a contact-operating cam 23. The knob is normally urged to the right by a spring 24 so that a projection 41 on a concentric ring 36 engages a recess 42 in the rear of the knob, so that rotation of the latter causes rotation of the ring 36 to set the duration of the operation relative to a scale 43 and the cam 23 closes contacts 13 to start the timing motor. To delay the start of the operation, the knob is pulled to the left and further rotated to the desired extent, the projection 41 riding over the rear face of the knob and the ring 36 being held against rotation by a friction pad 51. A motor restores the spindle over gears 14, 15, 16 and a friction clutch 18 until spring 24 moves the knob to the right when projection 41 and recess 42 re-engage, this movement causing cam 23 to close contacts 26. The spindle continues to rotate until a cam recess 27 comes opposite a projection 50 on contact arm 30, so that switches 13, 26 open. If the knob is turned so that its pointer 44 comes opposite numeral 4 on scale 43, switch 26 is closed, but a projection 29 on the cam holds motor switch 13 open, so that the timing mechanism becomes inoperative. Specifications 782,660 and 782,661 also are referred to.

An hydraulic pump or motor comprises a cruciform piston member whose arms 26 engage in cylinder members 18 which are free to slide on shoes 50, fixed to the casing 10. The piston member is mounted on an eccentric 28 on a shaft 30. Inlet ports 34 and outlet ports 36 alternately open into or are shut off from each cylinder space 32 by the movement of the member 18. Liquid from the cylinder space 32 is fed via restricted passages 42 (Fig. 2, not shown) to the spaces between the relatively moving surfaces of the eccentric 28 and piston member and between the cylinder member 18 and shoe member 50. These areas of sliding contact are larger than the piston area and are substantially symmetrical about the longitudinal axis of the corresponding arm 26. These areas are related to the passages 42 to give a predetermined thickness of lubricant and under varying flow conditions the passages 42 oppose changes of film thickness by causing corresponding inverse changes in the average film pressure. The pump or motor unit may comprise more than one bank of cylinders. One bank may be rotatable relative to the other and the cylinders interconnected so that the output may be varied from a maximum to zero when the cylinders are 180 degrees out of phase to each other.
