Patent GB-630850-A (GB)
Title: Improvements in or relating to sheet materials, and flexible abrasive articles, such as sandpaper, including the improved sheet material and methods of making the same
IPC: C09D167/06
Filed: 1945-12-21
Abstract: A composition for coating and/or impregnating sheet material is made by mixing a minor proportion of a phenol-aldehyde intermediate with a major proportion of an unsaturated polyester type of alkyd resin soluble in organic solvents, one component thereof being an unsaturated dibasic organic acid, and converting the mixture by heat to the hard infusible stage.  The phenol component may be phenol or para phenyl phenol.  The alkyd resin may be formed by condensing ethylene glycol or diethylene glycol with maleic anhydride, fumaric or itaconic acid, or halogen-substituted maleic or fumaric acid.  In an example a mixture of diethylene glycol and maleic acid is heated for three hours, and the acetone-soluble alkyd resin so obtained has a viscosity of 500 centipoises at 65 DEG  C. and an acid number of 60-70.  Other solvents specified are alcohols and ethyl acetate.  The Specification as open to inspection under Sect. 91 comprises also the use as an adhesive of the above composition in the lamination of preformed sheet material.  This subject-matter does not appear in the Specification as accepted.
Patent GB-875790-A (GB)
Title: Breathing control valve
IPC: A62B9/02
Filed: 1958-10-29
Abstract: 875,790. Artificial respiration apparatus. SEELER, H. W. Oct. 29, 1958 [July 7, 1958], No. 34719/58. Class 81 (2). A breathing control valve for use in artificial respiration apparatus comprises a housing having an inner chamber communicating with four passages, the first passage 14 being controlled by a one-way valve 12 to admit air to the chamber, the second passage 4 being connected to a source of intermittent positive and negative pressure, the third passage 30 communicating with atmosphere and the fourth passage 2 being connected to a source of intermittent positive pressure, and a valve member 24 movable between a first position, in which it seals the second and fourth passages from one another and permits communication between the third and fourth passages, and a second position, in which it closes the third passage and permits communication between the second and fourth passages. The valve is used in mouth-to-mouth artificial respiration apparatus, the second passage 4 being connected by a tube 6 to a mouthpiece 10 for the operator and the fourth passage 2 being connected to the patient. On inhaling through the tube 6 the operator draws fresh air into the tube 6 through ports 14 controlled by the one-way valves 12 and causes the valve member 24 to seat against a first opening 26 thus cutting off the first and second passages from the third and fourth passages. As the valve member 24 seats against the first opening 26, it permits communication between the fourth and third passages through a second opening 28 so that air in the patient's lungs escapes to atmosphere. When the operator exhales into the tube 6 the valves 12 close and the valve member 24 is unseated from the first opening 26 and seats against the second opening 28, thus allowing the fresh air in the tube 6 to pass through apertures 34 in the valve member to the fourth passage and the patient. At the same time, the third passage to atmosphere is closed.

Title: Improvements in or relating to web feeding mechanism
IPC: B65B41/16
Filed: 1937-02-27
Abstract: 490,342. Feeding webs. FITZGERALD, A. S. Feb. 27, 1937, Nos. 35002 and 35003. Convention dates, Feb. 27, 1936 and Sept. 19, 1936. Divided out of 490,305. [Class 100 (i)] A web-feeding mechanism which is especially applicable for registering a web 210 provided with registering marks 226 in relation to the cutting knife of a packing machine is constructed with a pair of feed rollers 212, 213, which are geared together and comprise at least one roller (213) with a resilient surface, and means are provided for varying the pressure between the surfaces of the two rollers in order to vary the speed of the web 210. The marks 226 preferably operate in conjunction with a photo-sensitive electric control device as described in Specification 490,305, which rotates a worm wheel 234, Fig. 2, when variation in the rate of feed is necessary. The feed roller 212 is mounted in fixed bearings and driven intermittently by Geneva gearing, and the roller 213 is mounted at each end in movable bearings 222, 223, which are moved against the action of a spring 236 by screw-mechanism to cause the web to be gripped with the desired pressure. The bearings 222 effect the automatic control of the feed, and are moved under control of the wheel 234 which rotates a screwed sleeve 233 engaging a screw bolt with a head 231 acting on the bearing 222. The bearing 222 is guided in a slotted yoke by means of pins 228. The bearing 223 can be adjusted manually by operating a lever 251 which is maintained normally in a vertical position by a spring-plunger 246 which engages a flat part on a sleeve 241 provided with a screw threaded portion 243 which engages a fixed thread to cause the sleeve to move quickly when the lever 251 is rotated. The lever can be rotated to a slight extent in either direction and is then arrested by stops. This permits the web to be slowed down or speeded up to secure an initial registration of the cutting knife with the web, and the register is thereafter maintained automatically. The sleeve 241 is fitted with a screw 240 which is set by hand initially and locked in position by a lock nut 242. This determines the normal pressure of the roller 213. The roller 213 can be moved away from the roller 212 to permit of threading of the web.

Filed: 1964-08-28
Abstract: The solubility in water of a water-soluble or unlimitedly water-swellable macromolecular carbohydrate or derivative thereof, especially of a cellulose ether, or of a polyvinyl alcohol or derivative thereof, is improved by treatment at elevated temperature with a dialdehyde polysaccharide in a proportion of 0.1-5% by weight, especially 0.3-5% by weight. Specified materials include cellulose ethers and esters, especially methyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose and mixed ethers of cellulose, starch ethers and esters, modified starches, vegetable gums, e.g. gum tragacanth and their derivatives, alginates, polyvinyl alcohol and its derivatives, especially partially etherified or esterified polyvinyl alcohols, e.g. polyvinyl acetate.  Specified dialdehyde polysaccharides include dialdehyde starch, and the dialdehyde forms of cellulose, dextran and galactomannan.  In general, the process is performed in a neutral medium and the mixture of the dialdehyde polysaccharide and macromolecular substance is heated to 60-130 DEG C., especially 90-110 DEG  C., suitably by drying the mixture in air at these temperatures. The dialdehyde polysaccaride may be mixed with the macromolecular compound in the dry state and the mixture moistened with solvent and/or water, or an aqueous solution of the dialdehyde polysaccharide may be employed which is dropped or sprayed on the macromolecular compound.  Various techniques are described, including the treatment of cellulose ethers while the latter are being converted from fibrous to particulate form.  Examples are given.

[Class 83 (iv)] [Also in Group XVI] In feeding strip stock for the continuous manufacture of tubes or the like from a band of metal, cardboard, &c. a " looping feed '' is employed to enable a new supply to be attached to the end of the old roll without stopping the machine. As shown, the strip a passes from a reel 1 between rollers 15, 16, under a knife 18, past a welding plant 24, 23, 21, between a roller 4 and a normally inoperative locking device 6, and finally around pulleys 28, 27, the latter of which is maintained in position by a weight 29. A circuit a, b, c, d, e, f is normally interrupted at 10, but when the supply fails, the roller 15 moves into the grooves of the roller 16 and the circuit is closed at 10 to energize an electromagnet 9 and withdraw a locking stop 7. The sectors 6 under the action of a spring 5 closes on the strip to render it stationary. The end is sheared by the knife 18 and a new strip engaged between the rollers 15, 16 and welded to the end of the exhausted strip.
