Abstract: 508,306. Mills and apparatus. JACKSON & CROCKATT, Ltd., J. G., and GAIR, D. Dec. 28, 1937, No. 35845. [Glass 59] [Also in Group I] A machine for subdividing loaves of broad, comestibles, soap or other agglomerates, into pieces, e.g. of such size as can be handled by a granulating-machine, comprises spaced cutters which make incisions in the material and means which tear or otherwise sever from the material, the pieces between said incisions. As shown, the materials are fed by a shoot 34 to two sets of saw discs 4, 5 which are arranged with spacers on shafts 2, 3, the shaft 3 being rotated quicker than the shaft 2 and having its spacers formed with claws 7 which effect the tearing. The discs 4, 5 overlap and the claws 7 are collectively arranged in helical form. The spacers between the knives 4 are of cylindrical form. Fingers or prongs 32, mounted on a rotating shaft 31, sweep the spaces between the claws which are thus freed from adhering material. The shafts 2, 3 are geared together and are driven through fast and loose pulleys 9, 10, worm gearing 12, 13 and variable speed pulleys 17 which comprise two pairs of fixed and adjustable members 16, 17 arranged to receive a V-pulley belt. Each adjustable member 17 is slidable and feathered on its shaft, and is controlled by a collar 22 mounted by a ball bearing 24 on the member 17 and connected by bolts to a lever under the control of a handwheel 29 on a screwed spindle. A jockey pulley 30 is provided.

Title: Improvements in or relating to the preparation of alumina-coated pigments and compositions containing them
Inventor: WILLCOX OSWIN B
IPC: C09C3/00
Filed: 1956-12-04
Abstract: Alumina-coated pigments are produced by mixing a pigment with an aluminium alcoholate or with aluminium phenate, and subjecting the mixture to dry grinding in the presence of superheated steam or water vapour, the aluminium compound being thereby hydrolysed. The process may be applied to any heat-stable pulverulent material, e.g. titanium dioxide, calcium and barium base pigments containing titanium dioxide, zinc sulphide, zinc oxide, or lithopone.  Suitable aluminium compounds include aluminium methoxide, ethoxide, propoxide, isopropoxide, butoxide, isobutoxide, and pentanoxide, also aluminium phenate.  The compound may be dissolved in an inert organic solvent and added, e.g. by spraying, to the pigment.  Examples describe the treatment of titanium dioxide pigments with aluminium isopropoxide solutions followed by mixing in a hammer mill and pulverizing in a high fluid energy disintegrator using superheated steam as the distintegrating agent; and comparisons of the products with pigments similarly treated but without the addition of aluminium isopropoxide, and with titanium dioxide pigments coated by a wet process. Specification 432,191, [Group II], is referred to.

Divided on 340,295. [Classes 123 (ii) and 123 (iii).] Water-tube boilers comprising one or more boiler drums 2 into which the watertubes discharge, have a succession of superheaters 3, 5 through which the steam is passed in alternation with heating elements 6 in the water space of the drums and of one or more separate evaporators 4 or of the evaporators only, and is eventually utilized in a multistage turbine or engine 7a, 7b, the steam generated in the evaporators being utilized in a separate circuit to resuperheat the directly generated steam while passing between successive stages of the turbine or engine. In modifications, the boiler comprises furnace wall tubes a part of their length being pinned or encased in blocks to shield a superheater chamber from the furnace. The final temperature of the superheated steam may be controlled by byepassing determined volumes of steam from some of the heating elements or by adjusting the water level of one or more of the evaporators as by a separate feed control or a throttle valve in the outlet. Different evaporators may receive feed water from a number of different circuits.

Abstract: 1,202,953. A battery of galvanic cells. VARTA A.G. 2 Aug., 1968 [19 Aug., 1967], No. 37108/68. Heading H1B. A battery of galvanic cells, in particular a fuel cell battery, has gas diffusion electrodes in which gas spaces of electrodes of the same polarity are arranged in individual groups of gas spaces which are connected together in parallel, the groups being connected together in series with respect to the gas flow and the number of gas spaces decreasing in successive groups. In preferred embodiments the last group may consist of the gas spaces of the electrodes of a single cell or of the gas space of a single electrode, or the gas spaces may be connected to a blow-off valve for removal of gaseous impurities, the valve being controlled by the electrical output of the electrodes of this last group. The diffusion electrodes may be non-porous e.g. a palladium or a palladium/ silver membrane, or porous. The gas spaces may be constituted by free spaces or may be filled with metal wool or with coarse metallic or ceramic powder. Preferably porous gas diffusion electrodes are used in which the gas space is a composite pore system of coarse porosity. In the examples, a fuel cell battery with hydrogen anodes and oxygen cathodes is used. The invention is applicable to all batteries in which gas diffusion electrodes are used e.g. potassium amalgam/oxygen and potassium amalgam/air cells in which the chemical energy of the potassium amalgam is obtained from the electrolysis of alkali metal chloride; an electrodialysis cell in which electro-dialysis takes place between a hydrogen diffusion anode and a hydrogen valve cathode and through an ionexchange membrane; purification cells to obtain pure oxygen and nitrogen using air cathodes arranged in groups and oxygen anodes and with the supply of electrical energy. Cells can be used which operate at room temperature with aqueous electrolyte, or at medium temperatures with fusible salt electrolytes and also fuel cells in which the electrolyte is a solid ion conductor.
