Title: Improvements in or relating to a process for preparing alkali-metal salts of the glycollic acid ether of cellulose
IPC: C08B11/12
Filed: 1943-08-17
Abstract: Alkali-metal salts of cellulose glycollic acid ether which are soluble or form colloidal solutions in water, are prepared by treating cellulose with monochloracetic acid or an alkali metal salt thereof in an excess of alkali hydroxide and a quantity of water not exceeding double the weight of the dry cellulose, the chloracetic acid or its salt being present in an amount between 50 to 100 parts per 100 parts of cellulose, and the mixture being heated for some time at 50-100 DEG  C.  Mechanical means are employed to thoroughly mix the reactants and to triturate the cellulosic material, the two operations being effected in one stage by treatment in a de-fibring device, or in two stages by treatment in a mixing and kneading apparatus followed by a crushing apparatus. In an example, cellulose is treated with sodium hydroxide and water in a mixing apparatus to which is subsequently added an aqueous solution of monochloracetic acid neutralized with sodium carbonate.  The product is then passed through a crushing apparatus and subsequently heated for some hours at 80 DEG  C.  The product may be purified by washing with alcohol, or by forming the free glycollic acid ether, washing with water and neutralizing with alkali.  Reference has been directed by the Comptroller to Specifications 138,116, [Class 2 (ii)], 469,901 and 482,885.

Title: High vacuum distillation apparatus
IPC: B01D1/22
Filed: 1956-05-01
Abstract: <FORM:0798221/III/1> <FORM:0798221/III/2> In a high vacuum distillation apparatus, particularly for molecular distillation, comprising a vacuum chamber 1 having a rotatably mounted shaft 8 carrying heated discs 12a, 12b and 12c which are heated to different temperatures relative to one another as described below, which partly dip into the distilland and which form vaporizing surfaces for the film of distilland formed thereon and condensers disposed between the discs, there are disposed between at least one pair of discs two separate condensers, e.g. 23 and 24, with separate systems for collecting the condensate from each condenser.  The distilland enters the sump through pipe 5 and residues leave by exit 21.  The sump is preferably divided into compartments by weirs 44 and partition walls 45 in the same plane as each disc.  The discs 12 are heated by passing a heating fluid from the reservoir 15 through tube 13, through holes 18 and through each disc in the order 12c to 12a, the liquid being deflected through the discs by baffles 19.  The liquid discharged from disc 12a returns to the reservoir 15 by tube 20.  In operation the chamber 1 is evacuated by suction applied at pipe 3. The shaft 8 is rotated and the discs, assisted by cups 43, pick up thin films of distilland which evaporate from the discs and the vapours condense on the adjacent condensers. The condensates are collected separately in collecting troughs and delivered to the separate collectors 40a, 40b, 40c, 40d, 40e and 40f.  The condensers may be cooled to different temperatures, if desired, either by having separate cooling systems for each condenser or by having a single cooling fluid which is cooled or heated between each condenser.  Also the two sides of any disc may be heated to the same temperature by using a perforated baffle in which case the condensates from the two adjacent condensers, e.g. 22 and 23, may be led to a common discharge pipe and collected together.  Specification 798,072 is referred to.

Abstract: 1,185,477. Engraving. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 9 May, 1967 [28 March, 1966], No. 13554/66. Heading B6J. [Also in Division G1] In a method of strain measurement where a pattern is inscribed on a surface before straining and a replica of the pattern is taken after strain and used to evaluate the strain, the pattern is formed by rotating a scratching tool about a stationary centre while changing the radius of rotation by small amounts to produce a series of arcuate scratches. As shown, the apparatus comprises a housing 2 supported on legs 4 and mounting a cylindrical rotor 6 comprising a barrel 8 and an enlarged end piece 10. Oil soaked material is positioned between the rotor barrel and the housing. The rotor base-plate 20 mounts a main slide 28 which support a further slide 35 to urge a spring-loaded pressure plate 40 against a stylus slide 44 to press the stylus slide into an aperture 38 of the main slide 28, the stylus slide 44 mounting a spring- loaded stylus 40. A reaction pin 52 mounted on the main slide 28 is engaged by one lever of a bell crank 54, pivoted at 58, its other lever engaging a pin 62 which contacts an adapter slide 64, to which is fixed a nut 68 encircling a lead screw 70. The rotor is driven by a motor 88 through gearing 90 clutch 82 and shaft 80; the drive for the lead screw 70 being taken from gear-wheel 86, pinions 94, 96 and through reduction stages 98, 100. Thus as the rotor is rotated the lead screw is simultaneously moved downwardly against the bell crank lever such that the stylus is moved radially outwardly to form a spiralling scratch. An indicator rod 78 extends through the hollow centre of the shaft. In use, a scratch pattern is produced on an unstrained surface, and a reproduction made of the pattern; after straining another reproduction is made and the two reproductions are compared by the MoirÚ fringe method.

Title: Improvements in or relating to valve apparatus for controlling fluids
Inventor: SEPHTON FRANCIS MORTIMER
IPC: G05D7/01
Filed: 1956-05-04
Abstract: 859,562. Valves. SISKOL MACHINES Ltd. May 6, 1957 [May 4, 1956], No. 13878/56. Class 135. A valve apparatus for controlling the flow of one fluid is controlled by the flow of another fluid through the medium of a pressure-sensitive actuating means for a gate type controlvalve operable in the duct for the controlled fluid and independent of variations in the pressure of the controlled fluid. The apparatus comprises a circular hollow body 10 having therein a fluid pressure chamber 13 divided by a flexible diaphragm 14 to provide a high-pressure compartment 15 and a low-pressure compartment 16, the diaphragm being urged towards the high-pressure compartment by a spring 17 and carrying at its axis a tubular valve member 18 in sliding engagement with the walls of the pressure chamber. A duct 24 having an inlet 25 and an outlet 26 is provided through which the controlled fluid flows. The duct is interrupted transversely by a guide bore 19 so that the tubular valve member 18 can be moved across the duct in closing engagement therewith. A further duct 29 having an inlet 30 and an outlet 31 is provided for the controlling fluid. A centrally orificed disc 32 is located at the inlet of the duct 29, the pressure on either side of the disc being sensed by the diaphragm 14 via passages 33 and 34. Instead of the orifice a Venturi may be provided. In operation, as fluid is allowed to flow through the duct 29 the highpressure compartment 15 senses the pressure upstream of the orifice 32 and the low-pressure compartment senses the downstream pressure to cause a pressure difference across the diaphragm to move it against the spring 17 and so slide the tubular valve member 18 to open the controlled fluid duct 24. Due to the fact that the valve member 18 is tubular and open at both ends it is not subject to any variations in pressure in the controlled fluid duct 24. The lower end of the valve member 18 opens into a sump 27. In another embodiment the tubular valve member 18, when in the open position, admits passage therethrough of the controlled fluid and thereby functions as part of the duct for the controlled fluid. In both embodiments the diaphragm 14 may be replaced by a piston.
