[Also in Division C3] A porous (poromeric) flat material is produced by impregnating a woven or non-woven fabric with a solution and/or an emulsion or dispersion of one or more monomers with at least two polymerisable double bonds or of a mixture of one or more of such monomers and one or more monoethylenically unsaturated monomers, which mixture contains at least 0.01% by weight (based on total monomer content) of the monomer(s) with at least two polymerisable double bonds, subjecting the impregnating monomer composition to complete or partial crystalline solidification, irradiating the solidified mass with actinic, visible light or high energy ionising radiation and, after reliquefying the liquid diluent of the mass, separating off the liquid. A polymer having a fibrous structure is formed in the treated fabric. In Examples the following fabrics are used: non-woven rayon staple, fibreglass, non-woven polyester, non-woven polyhexamethylene adipamide and non-woven cellulose fibre.

Title: Process for drying cellulose pellicles
IPC: B29D7/00
Filed: 1936-12-17
Abstract: To render uniform the shrinkage that occurs during the drying of regenerated cellulose films and to obviate the formation of creases &c., the drying is commenced by first bringing the wet film into an atmosphere saturated with water vapour and then progressively raising the temperature to the final drying temperature, whereupon drying is continued at this temperature, the water vapour content of the atmosphere surrounding the film being reduced by the admission of warm dry air or by the withdrawal of water vapour therefrom, in such a manner as to secure uniform drying.  Drying is conveniently carried out on heated drying cylinders, either air at the appropriate temperature and containing the requisite proportion of water vapour is blown on to the cylinders, or the latter are enclosed, which with the aid of partition walls enable the vapour contents of the atmosphere to be adjusted.

Title: Purification of solutions obtained in the production of hydrogen peroxide
IPC: C01B15/023
Filed: 1961-09-29
Abstract: Impurities are removed from partly decomposed working solutions obtained from the production of hydrogen peroxide by the anthraquinone process, by distilling off the solvents from the working solutions, treating the distillation residue with an aliphatic alcohol having 1 to 6 carbon atoms, separating the undissolved anthraquinone derivative from the alcohol and dissolving it in a solvent to prepare a fresh working solution. Specified alcohols are methyl, ethyl, isopropyl and n-propyl alcohols.  Acid products are removed from the distillate by treatment with alkali. The yield of anthraquinone derivative may be increased by additional operations:-A. the distillation residue is treated, before precipitation, with active alumina at elevated temperatures, with or without aeriation <PICT:0928783/III/1> with oxygen-containing gas; B. as A, using an oxygen-containing gas without the addition of alumina; C. the distillation residue is treated, while hot, with an aqueous solution of an alkaline substance, and is subsequently added to the alcohol; D after distillation off of the solvent the distillation residue is sublimed before treating with an alcohol.  The undissolved constituents obtained thereby may also be sublimed; E. the residue is subjected to a short-path distillation, prior to addition to alcohol and also thereafter; F. the residue is added hot to the alcohol and after separation of the solid, the mother liquor is freed from alcohol, which can be re-used, while the residue obtained thereby may be subjected to a treatment according to additional operations A-E; G. after dissolving the anthraquinone derivative in the distillate, the solution is treated with active alumina.  A preferred embodiment is that illustrated, in which part of the decomposed working solution may be removed at any place between extraction and reduction stages and is passed into a continuously operating vacuum distillation apparatus 1 from which the distillate is cooled in cooler 2, freed from acids by washer 3, and finally passed into stirrer vessel 4. The residue passes from 1 into vessel 5 filled with alcohol.  The solid anthraquinone is removed, after cooling, on filter 6, and passed into stirrer vessel 4, from where the purified working solution is returned to the anthraquinone cyclic process.  Examples are given in which the anthraquinone derivative is 2-ethyl anthraquinone.  Specification 831,036 is referred to.

Abstract: 619,259. Gas turbine plant. SOC. RATEAU, and ANXIONNAZ, R. Nov. 28, 1946, No. 35337. Convention date, Jan. 25. [Class 110 (iii)] The two stages c<1>, c<2> of the air compressor are driven by two stages a<1>, a<2> of a turbine, the low-pressure stages being on one shaft and the high-pressure on another. The compressor turbine is arranged in gas parallel with a twostage useful power turbine m<1>, m<2>. Reheating chambers are provided between the stages of each turbine. The temperatures of the combustion chambers and reheating chambers are kept substantially equal. The total compression ratio of the air-compressor is eight. The heat-exchanger R for heating the air by the turbine exhaust has an efficiency of not less than 0.6. The compression ratio of the low-pressure compressor and the expansion ratio of the turbine stage which drives it are greater than the corresponding ratios of the high-pressure compressor and its turbine stage. In regulation, the fuel supply to the initial combustion chambers is reduced more rapidly than the fuel supply to the reheating chambers.

Abstract: 1459907 Winding metal bar or rod DAVYLOEWY Ltd 25 July 1975 [12 Aug 1974] 35442/74 Headings D1J and D1T A winding apparatus for metal bar or rod comprises a vertically extending mandrel 1 having means 2 at its upper end for receiving an end of the bar or rod, there being means 8, 9, 10 for raising and lowering the mandrel 1 and guide means 17 spaced laterally of the mandrel 1 for guiding the rod or bar as it is wound onto the mandrel. The mandrel 1 is rigid with a splined shaft 3 that keys with and slides through a gear drive 5. The mandrel 1 may be surrounded by a sleeve 12. A pin 13 extending through the mandrel 1 projects into a pair of slots 14 in the sleeve 12 to cause the sleeve to rotate with the mandrel 1 and to permit the sleeve to have a limited axial movement relative to the mandrel 1. In operation the mandrel 1 is lowered until the sleeve 12 rests on a pair of supports 16. In this setting the upper end of the sleeve 12 is just below the floor level 15 and the upper end of the mandrel 1 is just above the floor level, the pin 13 being then at the top of the slots 14. The end of a bar or rod is placed in the slot 2, a turn is wound on the mandrel 1 and the mandrel is then raised to its maximum setting to enable the coiling of the bar or rod to be carried out. When the coil is finished the mandrel is lowered to a setting in which the sleeve 12 again rests on the supports 16 but on this occasion the mandrel is lowered further such that it is withdrawn within the sleeve 12 and no longer projects therefrom. In this setting the pin 13 is at the bottom of the slots 14. The coil can then be removed from between the rollers 17 by means of a crane and sling; alternatively, a remoyable floor plate surrounding the mandrel can be lifted by the crane with the coil supported on it and a replacement floor plate lowered into position.

In a null balance two path absorptiometer an optical wedge in the reference path is shifted by a pulse motor energized by an oscillator with a frequency proportional to the amplitude of the out of balance signal. Light from a monochromator 3 is switched alternately through a sample 6 and an optical wedge 7 to fall on a photocell 8 connected to a phase sensitive rectifier 9. The oscillator 11 has two channels each comprising transistor-capacitor relaxation oscillators having a frequency controlled by the magnitude of the output of rectifier 9 (one channel if the output is positive, the other if negative). The pulses are fed to a step-by-step wedge motor 13 and an up/down counter 14. The count may be used retro-actively in a chemical process control or to give an alarm at a pre-set value. Automatic titration The absorptiometer may be associated with an automatic titrimeter in which an oscillator energizes a step-by-step motor of a mechanical burette so as to record volume against absorption on a two channel recorder. Alternatively the burette motor may be stopped when a pre-set count on counter 14 shows that the end point has been reached. If the end point corresponds to a point of inflexion on the absorption curve, it may be detected by applying the pulses to a ratemeter and differentiator.
