Title: Intermittent driving mechanism, especially for electric sequential timer switches having an adjustable time interval
IPC: H01H43/12
Filed: 1967-02-16
Abstract: 1,140,335. Escapements. MALLORY TIMERS Ltd. 16 Feb., 1967 [16 Feb., 1966], No. 7546/67. Heading F2X. [Also in Division H1] A shaft 24 driving cams of a time switch (see Division H1) is stepped by a single revolution of shaft 20 at preselectable intervals. A motor 11 drives shaft 19<SP>1</SP> (coaxial with shaft 20) via worm gearing, and a helical spring coupling clutch 21 is normally held disengaged by abutment with a tang (56, Figs. 2 and 3, not shown) upstanding from a plate 26 pivoted at 27. Motor 11 has an axially movable output shaft such that when the motor is energized via a special tapping (70, Fig. 4, not shown) a cam 14 is lifted to urge plate 26 in the direction of arrow 48 against action of spring 31; this removes the restraining tang from clutch 21 and motor 11 then drives shaft 20. Tapping (70) is selectively energized by one of the switches 36, 37, 54 and 38 which are closed by respective actuators 34, &c. at different angular positions on a gear 28 driven via pinion 29 from shaft 19<SP>1</SP>. Gear 28 is carried on plate 26 so that it is disengaged from pinion 29 each time cam 14 moves plate 26, and a spring 40 then returns gear 28 to a fixed start position; thus shaft 20 is intermittently turned through one revolution at time intervals dependent upon which switch 36, 37, 54 or 38 is selected. Instead of the axially movable armature of motor 11 a separate solenoid may be provided to displace plate 26 when energized by the selected switch 36, 37, 54 or 38.

Patent GB-494556-A (GB)
Title: Improvements in the manufacture and production of alkali metal hyposulphites
IPC: C01B17/66
Filed: 1938-03-14
Abstract: Alkali metal hyposulphites are produced by reacting solutions of heavy metal, e.g. zinc, cadmium or iron, hyposulphites with alkali metal amalgam.  The heavy metal separates in part in metallic form, and is partly dissolved in the mercury, and partly dispersed in the aqueous solution.  Unreacted heavy metal hyposulphite remaining dissolved in the solution may be precipitated by alkali hydroxide, carbonate, sulphite or other suitable agent.  The two precipitates may be removed consecutively or simultaneously.  Sodium and potassium amalgams are specified, the amalgam produced by the electrolysis of common salt with mercury as cathode being advantageously used.  The amalgam is preferably used in stoichiometric excess, e.g. from about 5-15 per cent excess.  The process may be carried out continuously by leading the amalgam and solution countercurrently through a trough or tube.  The aqueous solution escapes over an overflow, and the mercury, which may contain unused alkali metal in addition to the heavy metal, through a syphon.  The heavy metal set free may be reconverted to hyposulphite, for example, by treatment with sodium bisulphite.  The mercury liberated is re-used for the preparation of the amalgam.  In an example, sodium amalgam is run, in an atmosphere of nitrogen, into zinc hyposulphite solution at 35 DEG  C.
