Title: A process for the preparation of alkaline earth metals
IPC: C22B26/20
Filed: 1954-10-19
Abstract: An alkaline earth metal is produced by reducing an oxygen-containing salt of the metal, e.g. the sulphate, by mixing the salt with a catalyst consisting of one or more of nickel, cobalt, vanadium, copper, and mobybdenum sulphide to obtain a mixture in powder form, maintaining the mixture at a temperature between 210 DEG C. and 300 DEG C. to reduce the salt to metal and then separating the metal from the catalyst.  The production of magnesium from magnesium sulphate is referred to using the salt in admixture with nickel oxide which is reduced to nickel in situ. Vanadium may be introduced as ammonium vanadate and copper and molybdenum sulphide as a cupro-molybdenum sulphide.  Magnesium may be separated from the nickel catalyst by vaporization, while still in a hydrogen atmosphere.  Preferably nickel or cobalt, both effective catalysts but sensitive to sulphur, is used in conjunction with one of the other stated catalysts which are less effective but less sensitive to sulphur.

Abstract: 1472314 Photo-multiplier operating circuit MEDICAL & ELECTRICAL INSTRUMENTATION CO Ltd 16 June 1975 [6 July 1974] 30076/74 Heading G1A [Also in Division G3] A photo-multiplier tube 12 is supplied with regulated current or voltage by a circuit 10 including a pulse generator which is blocked if the potential at a terminal Y exceeds a predetermined level see Division G3. The arrangement can be modified, Fig. 4, so that the tube gives a linearly changing output with a logarithmic incident light variation for use in optical densitometers or colour analysers, or a linear-linear output as required for measurement and control of photographic exposure. With switches 64, 70 as shown, the tube 60 is operated in the linear-log mode, and in the other switch state, the tube operates on a fixed voltage while its anode current is integrated 67, 75 and applied to a level detector 76 controlling a time exposure switch 77. Adjustment is made by varying the setting of a resistor 72 which may be replaced by a variable resistor (79) connected in series with the dynode resistor chain 68, Fig. 5 (not shown).

[Also in Division B8] Apparatus for loading a charging container with loose material measured by weight comprises a belt or like endless conveyer having an upper run to receive the loose material, a weigh frame which carries the total load-heaving length of the upper run, load measuring devices on which the weigh frame is supported and guide means for preventing the weigh frame from moving either longitudinally or transversely of the direction of travel of the belt whereby non-vertical forces acting on the weigh frame do not affect the accuracy of the load-measuringdevices. The upper run 3 of the conveyer belt is carried by rollers 5 which run on rails 7 supported by a weigh frame 11 and the weigh frame 11 rests on electromagnetic weigh gauges 12. There are normally four such gauges, but mention is made of the use of three gauges by the interposition of a balance beam transmitting the load to two of them. The load capacity of the belt is increased by retaining walls 9 supported by struts 10 from the weigh frame 11. Horizontal forces are resisted, while vertical movement for weighing is allowed by a longitudinal guide rod 14 and a transverse guide rod, across the frame 11, both of which may include turnbuckles to adjust their length and both of which are pivoted at one end to the weigh frame and at the other end to the frame of the apparatus.
