Abstract: 1295585 Microporous membrane GENERAL ELECTRIC CO 19 April 1971 [13 May 1970] 9865/71 Heading B5B A microporous membrane wherein the pores increase progressively in size across the membrane thickness and wherein the porosity is provided by a network of interconnected micropores extending through a mass of polymer crystals interconnected in a network of the same polymer, is made by dissolving the polymer in a mixture of a relatively good and a relatively poor solvent, the "good" solvent being the more volatile and the solvents being miscible, casting the solution on to a flat surface and allowing partial desolvation to occur, followed by immersion in a leaching agent, which is a non-solvent for the polymer but is miscible with both solvents, whereby a membrane forms by coagulation, the membrane being removed and dried. The polymer is a polyarylene oxide, polycarbonate, polyalkyl methacrylate or polysulphone. The largest pore size may be 100 . The film may have on its least porous surface a thin, dense skin (e.g. 100 -10 Á thick), this being obtained by extending the desolvation period. Specified polymer-good solvent-poor solvent-leaching agent combinations are: polymethylmethacrylate-acetoneformamide-water; a copolymer of bisphenol A and dichlorodiphenylsulphone or a polycarbonate - chloroform - toluene - methanol; and polyxylylene oxide - chloroform - dichlorobenzene-methanol.

Abstract: 1303425 Gas heater LAPORTE INDUSTRIES Ltd 27 Jan 1970 [28 Jan 1969] 4665/69 Heading H5H [Also in Division C1] A gas heater comprises an assembly 1 of graphite heating elements 2 which have been roughened by heating to at least 1000‹ C. in air and means for maintaining the elements in contact, the shape of the elements and configuration of the assembly being such that the " nominal contact " area between adjacent elements 2, i.e. the area of overlap, and the relative positions of the elements 2 remain unchanged in use. As shown the gas heater comprises a plurality of heating columns 1 formed by square section graphite rods 2. Each column has seven pairs of rods 2 stacked on top of one another, the elements of each pair being spaced apart for gas flow and having their axes parallel and perpendicular the axis of the column. Alternate pairs have their axes at right angles. Graphite pressure plates 6 at the top and bottom of each column keep the heating elements 2 in contact and graphite connector plates join the heat columns 1 in series between electrodes 8. Graphite baffles 9 prevent vertical temperature gradients in gas flowing through brick chamber 3 from inlet 4 to outlet 5. The heating elements 2 may be of inverted channel shape with one end of the base removed if desired. In the latter case, the elements are stacked on top of one another in a housing with the removed portions of the bases of adjacent channel elements at opposite ends so that a zig-zag gas passage is formed through the assembly. A heating column assembly with a zig-zag gas passage may be formed using rectangular plate heating element located in a casing by two columns of L-shaped heating elements, the rows of L-shaped elements being arranged along a pair of opposite sides of the column. The heating column assemblies 1 may be formed of stacked rods of, e.g. rectangular section, with the axes of the heating rods perpendicular to the column axis, and the axes of adjacent rods perpendicular. Where the heating assemblies comprise vertical stacks of heating elements contact pressure may be ensured by weights on top of the assemblies. If the columns are horizontal and the elements rest on a horizontal surface, contact pressure is applied by weighted levers. The surface on which the elements rest may be inclined so that frictional forces on the elements causing differential contact pressures on expansion or contraction may be counteracted by gravity. Alternatively, the heating elements may rest on rollers or rails. The heating columns 1 may be fed from a three-phase supply. The columns are arranged in three groups, each of which occupies a different length of casing 3 and is connected to one phase. The apparatus may be used for preheating a mixture of titanium tetrachloride and aluminium chloride vapour to 1000‹ C. prior to its vapour-phase oxidation in the manufacture of titanium dioxide incorporating alumina. Halides of silicon, zirconium and iron may also be heated in the apparatus.

Filed: 1969-04-02
Abstract: 1306801 Photographic silver halide material AGFA-GEVAERT AG 10 March 1970 [2 April 1969] 17161/69 Heading G2C A photographic material containing a silver halide emulsion layer comprises composite silver halide grains which contain internal sensitivity specks which have been produced by chemically ripening the core grains, and precipitating on the cores a shell of unripened silver halide, and in which the shells have been chemically fogged, the degree of chemical fogging of the shells being such that if the material were imagewise exposed and developed using an exposure E n , which is less than a certain exposure E max , which is the exposure necessary to give a maximum density then a negative image would be obtained, whereas if the exposure E p  which is used were greater than E max  a direct-positive image would be obtained, the development being carried out under the same conditions. The developer may be a lith-developer i.e. one which contains an addition compound of an aliphatic aldehyde or ketone with a bisulphite and hydroquinone as the sole developing agent. The cores and shells of the grains may comprise silver bromide. Chemical ripening of the cores may be effected with a compound of a noble metal (i.e. Au, Os, Ir, Pt, Ru, Rh or Pd) e.g. gold (III) chloride, a sulphur compound e.g. ammonium thiocyanate, a reducing agent or mixtures thereof. The pAg may be kept constant during the precipitation of the silver bromide cores. Chemical fogging of the shells may be effected with a reducing agent e.g. formamidine sulphinic acid. The degree of chemical fogging of the shells and the particular developer used determine whether or not negative and direct-positive images can be obtained from a particular material.

Abstract: 1308296 Laminated honeycomb material DUFAYLITE DEVELOPMENTS Ltd 27 Feb 1970 [11 March 1969] 12885/69 Heading B5N A formable structural honeycomb material is made from synthetic fibre paper-like sheets and is impregnated with a curable resin. The material may be expanded before impregnation and may be shaped, e.g. to a curvature, before curing the resin. The sheets may be of an aromatic polyamide containing a binder, and the impregnant may be a phenolic resin containing an inhibitor (to permit storage of the uncured product). As shown, the honeycomb is produced by applying adhesive, e.g. phenolic resin, in longitudinal bands to a web 1, drying the adhesive to a tacky state in a heating tunnel 3 and winding the web on to a flat former comprising detachable bars 11, 12. The wound product is then removed from the bars and is consolidated in a heated press to cure the adhesive and form a single block, and then sliced, expanded and impregnated. The registry of the adhesive bands is arranged to alternate from one layer to the next by alternating the operation of applicator rolls 20, 21. (Fig. 4, not shown). Distorted slices from the curved sides of the consolidated block may be satisfactorily expanded between non-distorted slices.

A vent tube 15 connects the cavity 2 with the atmosphere so that the liquid supporting the floats has a level a around the float 1 and a level c around the float 3, the air in the space between 3 and 4 depressing the level to c. A casing 5 supports a three leaf electric switch 7 operated by the float 3 pressing on the diaphragm 4, and a piston 13 may be moved to increase or decrease the air pressure in the casing 5 to affect the operation of the diaphragm 4 and vary the density tolerance range. In Fig.2 the piston 13 is not provided and the contacts of 7 are adjusted by turning a screw 19. In operation the apparatus is floated in a liquid and adjusted so that its contact 8 is in a middle position. If the liquid density varies then there is relative vertical movement between the floats 1, 3 and the contact makes either one leaf or the other of the switch 7 to indicate on two signal lamps the raising or lowering of the density, Fig.3 (not shown) or to arrange for relays and magnetic valves to be operated and make provision for the liquid to be either automatically diluted or strengthened, Fig.4 (not shown). In a modification the electric switch can be replaced by pneumatic controls or by micro-switches or tilting mercury switch tubes.
