Title: Improvements in or relating to processes for the production of electrically insulating materials
Inventor: ASHPOLE RAYMOND SIDNEY
IPC: H01B3/08
Filed: 1964-08-17
Abstract: An insulating material in strip on sheet form is made by coating a porous backing material with fibres or flakes of an insulating material e.g. mica, applied electro-phoretically from a suspension thereof.  The backing sheet e.g. open weave glass fabric passes in contact with or close to a sheet anode remote from the cathode.  A suitable suspension consists of mica flakes, and <PICT:1119441/C6-C7/1> distilled to which acetone and a dispersing agent e.g. montmorillonite may be added.  The dried coating may be treated with a resin binder, and may be stripped of the backing; alternatetively resin may be added to the suspension.  A bath of the suspension 11 containing .5 to 10% by wt. of mica flakes is circulated from a reservoir 19 to keep the composition uniform and in which is mounted vertically a cathode 13, and anode 12 spaced from the cathode and extending beyond the surface of the bath. Glass fabric tape 14 passes over the face of the anode to which a D.C. voltage of 100V is applied.  The coated tape passes over the face of a pulley 17 which is evacuated internally to dry the tape, and then to a drier 18.  For alternative arrangements, a continuously moving belt anode is used Fig. 2 (not shown); the coated tape is pressed by a second tape of open mesh to which the mica coating is transferred Fig. 3 (not shown); and the mica coating after consolidations by pressing with a continuous belt is stripped off Fig. 7 (not shown), in the last form the first coated tape is also in continuous belt form and the sheet anode is substantially horizontal.

Title: Production of sorbic acid
Inventor: JOWITT HUBERT
IPC: C07C51/09
Filed: 1958-10-21
Abstract: Sorbic acid is produced by reacting ketene with crotonaldehyde in the presence of zinc sorbate as catalyst, and hydrolysing the resulting product to sorbic acid.  Ketene is preferably reacted with crotonaldehyde at a temperature in the range from 0 DEG C. to 60 DEG C. with 0.1% to 5% by weight of zinc sorbate.  The reaction may be carried out in the presence of an inert solvent or gaseous ketene may be stirred with a mixture of liquid crotonaldehyde and zinc sorbate. The product, which is believed to be a lactone, may be hydrolysed to sorbic acid by treating with an aqueous solution of a mineral acid such as sulphuric acid, after removal of any solvent present.  The hydrolysis is preferably effected as described in Specification 868,028 by heating with an aqueous solution of an alkali metal hydroxide, such as sodium hydroxide, to separate solid alkali metal sorbate from the resulting mixture and reacting the sorbate with an acid having a dissociation constant greater than sorbic acid to produce sorbic acid.

Abstract: 1,023,139. Centrifugal separators. DONALDSON CO. Inc. Aug. 23, 1963 [Oct. 29, 1962], No. 33555/63. Heading B2P. The air cleaner described in Specification 907,871 is modified by replacing the cup-like removable dust-collecting cap by a removable end wall 4, Fig. 1, providing a depending dust outlet tube 12 in communication with the annular air inlet passage 9 and connecting an automatic unloading dust valve 14 to the outlet tube 12. The housing 1 is arranged with its axis horizontal instead of vertical. The valve 14 is made of rubber-like material and comprises a cylindrical anchoring flange 15 stretched over the outer end portion of the outlet tube 12, a radially inwardly extending, annular diaphragm-acting wall 16 and a throat 18 having opposite side portions 19 which are progressively relatively flattened so as to converge from a cross-sectionally substantially circular end portion 20, Fig. 4 (not shown), to relatively closely spaced lips 21, defining a normally open, lenticular discharge mouth 22, Fig. 5 (not shown), which automatically closes in operation under the action of partial vacuum in the housing 1, e.g. when the air cleaner outlet 6 for clean air is connected to an I.C. engine air intake. In operation, dust particles 27 separated by centrifugal force accumulate within the discharge tube 12 and throat 18. Due to variations in the partial vacuum a pulsating action is set up which is transmitted to the diaphragm wall 16 of the valve and which, combined with the weight of the accumulated dust particles 27, causes periodical opening and closing of the mouth 22 to discharge the dust.

Title: Improvements relating to anion-exchange resins
Inventor: KRESSMAN THEODORE ROGER ERNEST
IPC: C08F8/32
Filed: 1955-11-23
Abstract: Anion-exchange resins containing two or more nitrogen atoms in each anion-exchange group are prepared by reacting under alkaline conditions a cross-linked polymer containing haloalkyl groups, an o -ethylene oxide substituted alkyl halide, and a primary or secondary amine to form an intermediate polymer which is further reacted with an amine.  The o -ethylene oxide substituted alkyl halide and the amine may be reacted together and then reacted with the polymer or, in a modification, the polymer may be reacted with the amine and then with the o -ethylene oxide substituted alkyl halide, and the products finally reacted with an amine.  The polymer may be polystyrene cross-linked with divinyl benzene or ketone and in examples beads of chlormethylated polystyrene cross-linked with divinyl benzene are reacted (1) swollen with benzene, with 3-diethylamino-1,2-epoxypropane, a reaction product of diethylamine and epichlorhydrin in a medium made alkaline with caustic soda, and (3) swollen in ethylene dichloride with diethylamine and then with epichlorhydrin in dioxane, to form intermediate resins which are reacted with diethylamine or trimethylamine to give strongly basic resins of high anion exchange capacity.
