IPC: B01L7/00
Filed: 1946-03-08
Abstract: 615,238. Heating by electric resistances. MOREY, G. H. March 8, 1946, No. 7260. Convention date, April 28, 1945. [Class 39 (iii)] A heater comprises an article-receiving pocket shaped to conform to the article to be heated and forming a rigid refractory non-conducting support 4 having embedded therein a wire or ribbon heating resistance 3 held in place by refractory spacers 5 such as beads or clips. A refractory fabric 1 e.g. of glass or asbestos is sewn with ribs to the required shape and sewn to the spacers and heating elements, and cement 4 or a plastic refractory such as fireclay is added to embed the spacers and resistances, the cement then being set to the required shape by heat. The fabric 1 forming a lining may be of combustible cloth burnt off after formation of the heater. The liner 1 may be of plastic material shaped as required and sewn to the beads. The resistance may be more closely spaced at certain parts. The support 4 may be placed in a steel or asbestos shell 2 filled with magnesia or asbestos 6. The heater may be concave for heating a glass flask or may be in segments for assembly round an article e.g. a valve in a pipe. The heaters of the segments may be connected in series or parallel. The heater may be convex to heat concave surfaces such as the inside of articles.

Title: Improvements in or relating to the hydrolysis of cellulosic materials
IPC: C13K1/02
Filed: 1939-03-09
Abstract: 536,759. Saccharifying cellulose. REEMTSMA, P. F., and WARTH, C., [trading as CHEMISCHE FABRIK LOWENBERG, Dr. WARTH & CO.]. March 9, 1939, No. 7716. Convention date, March 22, 1938. [Class 127] In hydrolysing cellulosic materials, such as wood, potato tops, cotton-spinning waste, &c. by suspending the material in an organic liquid and treating with hydrogen halide, the material is first soaked in hot or cold water or in dilute acid. It may in addition be treated with chlorine and sulphur dioxide. If the material contains resin, this is first extracted by a volatile solvent. The organic suspension liquid may be benzene mixed with tetra- or deca-hydronaphthalene and carbon tetrachloride so as to have a specific gravity high enough to maintain the material in suspension and may contain a wetting-agent such as methyl hexaline or a flotation agent. A temporary emulsion of aqueous acid and organic suspension liquid is formed and the suspension separates into two layers after introduction of the cellulosic material and during the hydrolysis, one layer consisting of an aqueous solution of sugar and the other layer containing the.lignin in suspension. The reaction products may be passed in counter-current with water or dilute acid. The sugar solution, if to be used for fermentation, is neutralized with ammonia. Specifications 376,322 and 488,897 are referred to.

Examples are given of coating wood, glass and polyester film; fibre-board, hardboard, nylon and polyethylene may also be treated.  The ionizable organic compound may be an organic acid, base or salt; the preferred compounds are quaternary and diquaternary ammonium halides.  Other suitable compounds are the alkyl and aryl esters of the acids of phosphorus and sulphur.  They may be applied in an aqueous alcoholic medium by wiping with a rag, spraying or brushing, and air- or force-dried.  The coating particles used in the example were composed ofa nitro cellulose lacquer containing natural resins and alkyd resins.
Patent GB-1068791-A (GB)
Title: Process for producing foamed olefine polymers in sheet form
IPC: C08J9/06
Filed: 1965-02-23
Abstract: A foamed olefine polymer in the form of a sheet is produced by melt-blending the olefine polymer with a thermally decomposable blowing agent, forming this mixture into a sheet, irradiating it with 0.5-50 Mrad of an ionizing radiation, and thereafter, while floating the sheet on the surface of a liquid heated to a temperature sufficient to activate the foaming agent, irradiating the sheet from above with heat so as to effect the foaming thereof.  The term "olefine polymer" specifically includes homo- and copolymers of aliphatic olefines; a mixture of 100 parts of such a homo- or copolymer with 10-500 parts of a natural or synthetic rubber, including silicone rubbers; a mixture of such a homo- or copolymer with a vinyl acetate/ethylene copolymer containing 5-50% by wt. of vinyl acetate; and an ethylene/vinyl acetate copolymer containing 50-95% by wt. of ethylene. Specified foaming agents are of the type which yield N2 on heating, e.g. azodicarbonamide.  The ionizing radiation may be electrons, gamma rays, X-rays, neutron rays or proton rays.  The heating liquid may be any that has no adverse effect on the sheet, and which is liquid in the desired temperature range, e.g. ethylene glycol, a silicone oil, molten low melting salts (e.g. nitrates), and molten low melting metal alloys.  The heating from above is suitably effected using I-R, but any heat source emitting in the preferred range of 1000-4500<\>rA may be used. The process may be batch or continuous.

Abstract: 1,220,205. Non-consumable arc electrodes. D. G. BYKHOVSKY and A. Y. MEDVEDEV. 14 Feb., 1969 [15 Feb., 1968], No. 8040/69. Heading H5H. A hafnium insert 14 is used in the cooled cathode holder 2 of a non-consumable arc electrode device for arc-working operations in the presence of a reactive gas. Plasma-generating gases such as air, carbon containing gases, oxygen, nitrogen or mixtures of gases containing nitrogen or oxygen, are supplied at 13, and the arc discharge 5 passes through one or more nozzles 3, 7. The hafnium reacts with oxygen, nitrogen or carbon to cover the cathode surface with a thin film of high-melting poin toxides, nitrides and carbides of hafnium having a low work function, i.e. high electron emission. This film prevents further reactive diffusion of the reactive gases into the cathode and thereby prolongs its operational life. Applications to the cutting of metals, such as steel, surface treating cast products and heating chemically-active gases and their mixtures are mentioned.

Abstract: 377,617. Change-box looms. SOC. ANON. A. SAURER, Arbon, Switzerland. March 21, 1932, No. 8417. Convention date, March 20, 1931. [Class 142 (iii).] Checking shuttles and pickers; changebox motions checking picking sticks.- In change - box looms, a single brake tongue or swell 16, Figs. 1 and 4, is mounted on the lay independently of the shuttle boxes and co-operates with the particular compartment that is moved into picking position. The swell pivoted at 17 on the lay has an inclined surface 41 adapted to be engaged to remove the pressure on the shuttle during shuttle change by a surface 40 on a spring-controlled bell-crank lever 39, 36 on the lay. A cam surface 37 on the part 36 serves as a stop to limit the outward movement of the picking stick. When the shuttle box is being changed, one or both rollers 26, 27 on levers 28, 29 are moved out of notches in crank discs 22, 23 thereby depressing a rod 35 pivoted to the bell-crank lever 39, 36. The lever is thus turned and causes the surfaces 40, 41 to be engaged to remove the pressure of the swell, and, at the same time, allowing the picker 14 to move out of contact with the shuttle tip 21. The swell may be arranged at the rear side of the shuttle-boxes, and the invention may be applied to looms having rotary shuttle-boxes.

Abstract: 369,388. Pocketknives. DUNGWORTH, S., 40, Bramall Lane, Sheffield. March 19, 1931, No. 8425. [Class 30.] In a pocketknife having detachable blades or other instruments the blades and scales are separated and reassembled by use of a key m inserted through keyways l in the scales and turned to relieve the pressure of the spring c on the blade d or blades at one end and allow their headed pivot i to be withdrawn through an L-shaped slot h in the scales. After removal of the key, the upper scale a is removed by giving it a partial turn to free keyhole slots g, k therein from the headed centre pin f and the opposite blade pivot j which is normally retained in the small ends of kevhole slots in both scales by the spring pressure. The blade e can then be removed, leaving only the lower scale with the centre pin f<1> and spring c permanently attached to it. A stop n limits rotation of the key. When only one blade is mounted on a pivot it is fixed thereto ; when more than one are so mounted they are loose on the pivot, but are prevented from removal by the heads of the pivot.
