Title: Improvements relating to nuclear reactors
Inventor: RIGG SHEPHERD
IPC: G21D1/02
Filed: 1966-11-18
Abstract: 1,134,520. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 13 Nov., 1967 [18 Nov., 1966], No. 51744/66. Heading G6C. In a pressurized water reactor steam generating system, steam is formed in a vortex-type pressure reduction device external to the reactor. Coolant water from the reactor vessel 1 flows to the vapour generator 5 through duct 4. The drop in pressure at 8 after coolant flow through the coolant chamber 10 causes the generation of steam in the central vortex. Steam is led to the utilization plant through duct 12. Repressurization is induced in the diffuser 9 connected to the return inlet 3. Circulation is maintained by natural convection. The by-pass 6 may accept half the total flow. A make up connection 13 leads to the diffuser 9.

Abstract: 1,174,098. Moulding reinforced cellular cellulose sheets. SPONCEL Ltd. 18 Nov., 1966 [22 Nov., 1965; 15 April, 1966], No. 51838/66. Heading B5A. [Also in Division C3] Cellular cellulose sheet material, reinforced by randomly oriented fibres, is made by extruding a mixture of viscose, a removable filler, such as sodium sulphate and reinforcing fibres through an adjustable slit die 12 and between a pair of transversely disposed belts 20, 21, the facing surfaces of which move in opposite directions. The facing surfaces frictionally engage the faces of the sheet and disrupt the longitudinal orientation of the fibres imposed by the extrusion thus giving a random orientation to the sheet. The randomly oriented sheet is subsequently fed on to take-off conveyer 13 whence it is passed through a coagulating and leaching bath. The die comprises a trapezoidal chamber 14 terminating in a fixed lip 16 and an adjustable lip 17, and the extruded sheet is fed to the belts through a sleeve 24 and is retained in position between the belts by bars located between the belts. In an alternative embodiment the freshly extruded sheet is engaged between a stationary surface and one moving belt.

Title: Continuous emulsion polymerization
Inventor: HERRLE KARL
IPC: C08F2/00
Filed: 1965-12-31
Abstract: A process for the continuous emulsion polymerization of conventional olefinically unsaturated monomers which are practically insoluble or at most partly soluble in water, in aqueous medium in the presence of conventional polymerization catalysts, comprises continuous supplying monomers exclusively in the form of a preformed aqueous emulsion through a tube in an upward flow at a flow velocity of 5 to 100 cm. per sec. to the lower part of a vertically arranged circulation system, blending with an excess of polymer dispersion which has already formed, and polymerizing in the circulation system without the use of mechanical stirrers to a mean conversion of more than 75%, the polymer dispersion being withdrawn at a point not higher than the point of entry of the monomer emulsion into the circulation system and at the same rate as the monomer emulsion is supplied. Optional process features include preblending of monomer with polymer, a temperature difference between ascending and descending parts, bubbling inert gas through the ascending part, boiling the ascending dispersion with the aid of reduced pressure, and complex circulation systems.  In examples, monomers polymerized are: (1) butyl acrylate-acrylic acid, (2) and (3) methyl methacrylate in the presence of dispersed polymethyl methacrylate, (4) and (5) butyl acrylate-vinyl acetate-acrylic acid, (6) and (7) vinyl propionate-sodium vinyl sulphonate, (8) styrene-acrylic acid-acrylonitrile, (9) vinylidene chloride-acrylonitrile-methacrylamide and (10) butyl acrylate-vinyl acetate-sodium vinyl sulphonate-acrylic acid; the catalyst being potassium persulphate or azodiisobutyronitrile and the emulsifier being selected from dodecylbenzene sulphonate, C10-C16-alkyl sulphonate, polyethoxylated octadecyl alcohol, turkey red oil and sodium salt of sulphochlorinated paraffins.  The process can also be applied using other monomers such as ethyl acrylate, vinyl pivalate, vinyl chloride, methacrylic acid, acrylamide and N-methylolmethacrylamide; and with other catalysts, e.g. hydrogen peroxide, ammonium persulphate, benzoyl peroxide and dialkyl percarbonates.
