Title: An improved filter sieve for use in filtration of liquid bodies carrying suspended solid material
IPC: B01D39/12
Filed: 1934-03-24
Abstract: A filtering partition, applicable for use in filter-presses or centrifugal filters, comprises a finely-perforated sheet or wire-gauze sieve united to a coarsely-perforated relatively-stiff backing sheet by an intervening film of fused metal which extends over the inter-foraminal area of the backing sheet.  The partition may be made by passing the assembled sheets between rollers through an electric oven at a temperature ranging from 400 to 500 DEG  F. When the fine sieve is of wire gauze, the fusible metal is preferably provided in the form of a very thin sheet, for example of tin or solder, having perforations in register with those of the backing sheet.  When the fine sieve is a perforated metal sheeting, the film of fusible metal is obtained by dipping the backing sheet in a bath of the fused metal.ALSO:A filtering partition, applicable for use in centrifugal filters, comprises a finely-perforated sheet or wire-gauze sieve united to a coarsely-perforated relatively-stiff backing sheet by an intervening film of fused metal which extends over the inter-foraminal area of the backing sheet.

Title: Improvements in and relating to the production of fine fibres from ramie or china grass
IPC: D01C1/02
Filed: 1940-05-30
Abstract: 540,123. Obtaining fibres. CELEC CORPORATION, Ltd., and TOWNSEND, C. S. May 30, 1940, No. 9485. [Class 2 (ii)] Fibres are obtained from ramie or china grass by stripping the fibrous bark from the plant in the green or undried state, maintaining the strips or ribbons in their soft green condition by immersing them, with or without previous scraping, in a neutral liquid such as water to keep the strips out of contact with the air until degumming is to be effected and effecting the degumming by removing the strips from the neutral liquid and while still soft, boiling them in a bath of liquid solvent ; the ribbons of stripped green bark may be immersed in the neutral liquid for from 1 to 2 hours and the solvent bath may comprise sodium carbonate and caustic animal tallow soap. In an example the ribbons immediately after their removal from water are boiled for about 30 minutes in a solution containing 5 per cent by weight of native unrefined sodium carbonate and 2¢ per cent. by weight of caustic animal tallow soap, the ribbons are then removed from the solution washed and immersed for about 5 minutes in a heated 2 per cent solution of hydrochloric acid at about 80‹C.; after washing the mass is again boiled for about 10 minutes in a solution containing 2¢ per cent by weight of the carbonate, 2¢ per cent of the soap, 2¢ per cent of sodium hydrosulphite and ¢ per cent of phenol and is thereafter thoroughly washed, pressed and dried.

Title: Improvements in or relating to thermionic gas discharge tubes
IPC: H01J17/56
Filed: 1952-04-16
Abstract: 734,586. Thermionic valves. RADIO CORPORATION OF AMERICA. April 16, 1952 [April 24, 1951], No. 9598/52. Class 39 (1). The deionizing time of a thyratron is reduced by providing means other than the cathode for heating at least a portion of the gas filling which is adjacent to the anode. In one arrangement, Fig. 2, a thyratron comprises an indirectly-heated cathode 12, a cylindrical control grid 13 having a slot 16, and an anode 14, contained in a gas-filled envelope 11. The heating means is an auxiliary discharge between a tungsten or thoriated tungsten filament 15 and a subsidiary anode 21. Alternatively, a small area of the grid 13 or of the main anode 14 may be used in place of the subsidiary anode 21, and the filament 15 may be replaced by an indirectly heated oxide type of cathode. The filament 15 is preferably positioned in alignment with the slot 16, although it may be positioned anywhere between the grid 13 and anode 14. In place of an auxiliary discharge, the filament 15 may be used alone as a simple resistive heater. In an alternative arrangement, Fig. 3, a subsidiary cathode 20 and anode 21<SP>1</SP> are located inside a box-shaped shield 19 adjacent a foraminated portion 17 of the anode 14<SP>1</SP>. The shield 19 may be polarized below the potential of the anode 14<SP>1</SP> to assist the drift of hot electrons through the portion 17 towards the interior of the anode. The tube may be connected across a condenser in a relaxation oscillator circuit for generating a sweep voltage for an oscilloscope, and is triggered by applying a pulse to the grid. In embodiments utilizing an auxiliary discharge as the heating means, a resistance is connected in the energizing circuit to limit the current of the auxiliary discharge to a very small value, since the auxiliary discharge is intended as a source of hot electrons and not as a source of plasma.

Suitable pressure sensitive adhesives are stated to be paraffin wax or microcrystalline wax containing a tackifier such as polyisobutylene.
Patent GB-853637-A (GB)
Title: Films from linear high polymers of propylene and process for their production
IPC: B29C48/08
Filed: 1957-03-25
Abstract: Polypropylene films are made by casting on to a heated solid casting surface a layer of a solution of a solid crystallisable linear high polymer of propylene in a solvent which can be volatilized by heating without decomposition, stripping from the casting surface the film thereby formed and imparting molecular orientation to the film by stretching it at an elevated temperature in two directions at right angles to one another.  The preferred solvent is kerosine, especially kerosine boiling between 170 DEG C. and 250 DEG C.  The polypropylene preferably has an intrinsic viscosity, as measured in tetrahydronaphthalene at 135 DEG C., of 0,5 to 7.  The film may be stretched at 80 DEG  to 150 DEG C. with a stretching ratio of 1:3 to 1:12 and subsequently stabilized by maintaining it at 130 DEG -150 DEG C. for 2-15 seconds while under tension.  In an example, a 30% by weight solution of polypropylene (of intrinsic viscosity 4,3) in a kerosine fraction boiling at 200 DEG  to 210 DEG C. is cast into a film on a rotating casting drum the surface of which is heated by means of an internal jacket through which a liquid at 175 DEG C. is circulated to evaporate the solvent. A countercurrent of air at 175 DEG C. is passed through an annular evaporating chamber surrounding most of the circumference of the drum.  After a residence time of 25 minutes on the drum the film is stripped from the drum, quenched in water and wound up.  The film is then stretched in a bath of ethylene glycol at 135 DEG C. first longitudinally with a stretch ratio of 1:4 and then transversely with a stretch ratio of 1:3.  The film is then heated at 130 DEG -140 DEG C. for 3 seconds while held stretched. The polypropylene solution contains 0,15% by weight of diphenylethylphosphite as antioxidant.  The process permits the production of polypropylene films having a molecular weight higher than that of films produced by melt extrusion.
