Title: Improvements relating to the treatment with alkaline media of threads, fibres, fabrics or similar objects composed of or containing cellulose acetate
IPC: D06P1/673
Filed: 1934-02-13
Abstract: In the dyeing, printing, and like treatment of threads, fabrics, and the like of cellulose acetate by processes involving the use of alkaline media, for example, in dyeing with vat-dyes and sulphur-dyes and in the discharge printing of anthraquinone dyestuffs by means of hydrosulphite in presence of quaternary ammonium salts, the alkali used is magnesium hydroxide.  In an example, cellulose acetate fibres are immersed in a vat containing sodium hydrosulphite, magnesium hydroxide, and Indigo N2B, rinsed, and treated with a solution of sodium perborate.  In another example, a cr<\>zepe fabric composed of cellulose acetate fibres and regenerated cellulose fibres, dyed with Duranol R and Melantherine BH, is printed with two rollers, the first applying a paste of Leucotrope W, thiodiglycol, zinc formaldehyde sulphoxylate, magnesium hydroxide, Rhodamine B, and gum arabic solution, and the second a paste comprising Leucotrope W, thiodiglycol, zinc formaldehyde sulphoxylate, magnesium hydroxide, and gum arabic solution.  The blue fabric is printed with patterns in white and red.

Title: Improvements in and relating to apparatus for and a method of metallising articles
IPC: H05K3/14
Filed: 1947-02-19
Abstract: 689,563. Coating with metals. SARGROVE ELECTRONICS, Ltd., and SARGROVE. J. A. Feb. 19, 1948 [Feb. 19, 1947], No. 4836/47. Class 82(ii) Articles of plate-like form which are susceptible to warping are sprayed with molten metal simultaneously on both sides by spraying devices past which the articles are conveyed. The apparatus shown is a modified metal-spraying stage of the complete apparatus for the production of electrical apparatus described in Specification 570,877, [Group XXXV], and is automatically controlled by means described in Specification 689,561, [Group XXIX]. Such metal-spraying stage comprises cubicles 10, 11, 12 through which passes a conveyer 19. 20 carrying panels to be coated. On either side of the conveyer are gun assemblies 27, 28, Fig. 5, each arranged to rock about a shaft 24 and comprising rods and tubes 26, carrying, and conveving gases to, spray guns 31. The wire to be sprayed is stored on drums 57, Fig. 2; and passes over pulleys 60. 65. 67, 69 to feed rollers 36, continuously driven by an electric motor through shafts 46 and bevel gearing 48, 49. The wire is held against the rollers 36 by backing rollers 37, Fig. 8, forced into contact therewith by air pressure applied to the nozzles acting on diaphragms 41, the movement of the shafts 39 carrying the rollers 37 being limited by stop means. The pulleys 67 are also driven but grip the wire, which passes completely around them, onlv when tension is applied thereto by the rollers 37. The spray gun assemblies as a whole are driven by double acting air cvlinders to the ends of which comnressed air is admitted through electromagnetically operated values under the control of limit switches, the connecting rods being attached to the assemblies at 56A. The consumption of wire is monitored by microswitches actuated by arms moved by pins on the pulleys 69. Gases are fed through the pipes 77 to a main cock 80, manually operable to cut off all supplies, and electromagnetically operated valves 82 operated in sequence for ignition and main-' tenance of the metallizing flames, a pilot jet with sparking plug being provided for the ignition of each main flame. At each spraying station, of which there may be six, an inner cubicle 85, Fig. 5, is provided, such cubicles being attached to a high capacity exhaust system: spraying is effected through slots in these cubicles. The conveyer may be protected against the spray metal by highly polished rollers rotating against scraper blades or by highly polished plates meeting a knife edge.
Patent GB-827923-A (GB)
Title: A process for producing sugars from cellulosic material
IPC: C13K1/02
Filed: 1958-02-14
Abstract: Sugars are produced from cellulosic material containing cellulose, lignin, and hemicellulose, by first contacting it with an anhydrous solution of hydrogen chloride in an organic solvent for the acid, lignin, and the products of hydrolysis of hemicellulose, until the hemicellulose is hydrolysed and the lignin is dissolved.  The hydrogen chloride solution, 30-40% concentration, in ethanol, n-propanol, or preferably, methanol, is passed upwardly through a column of the material in finely-divided form of 0.3-1.5 mm. in diameter at a temperature of 15-30 DEG  C. The lignin in the solution is precipitated by the addition of water.  The residue is then treated with an aqueous solution of 40-42% concentration of hydrogen chloride by passing it upwards through the column whereby the organic liquid solution is displaced and the cellulose is hydrolysed. Specifications 827,921 and 827,922 are referred to.

Abstract: 1,168,113. Rotary printing presses. G. RITZERFELD. 2 Feb., 1967 [8 Feb., 1966], No. 5194/67. Heading B6C. A rotary hectographic duplicating machine is provided with means by which an exhausted master sheet is restored to its original condition whilst mounted on the printing cylinder. In the described embodiments such means take the form of mechanism by which the exhausted master is covered with the coated side of a hectographic dye-stuff transfer sheet and irradiated by an infra-red heater. After restoration, the transfer sheet is removed, if desired, automatically, and the duplicator is ready for further use. Instead of infra-red irradiation, the electrode of a high frequency generator may be used. The printing cylinder is associated with cam means by which the radiator is switched on only whilst the assembly of master and transfer sheet is passing therebeneath.
