Abstract: 1,214,103. Extruding thermoplastics sheets. PLASTILUOR S.A. 27 March, 1969 [3 April, 1968], No. 16005/69. Heading B5A. [Also in Division F2]  The surface A of an extruded thermoplastics sheet F, e.g. a sheet of polymethyl methacrylate, polystyrene or vinyl chloride, is rendered matt by application whilst malleable against the roughened surface of a lining 4b of roller 4, the material of the lining being of low thermal conductivity and sufficiently soft not to produce facets of high surface brilliance. The lining is preferably of a silicone elastomer, but may be of a suitable synthetic rubber such as neoprene, or P.T.F.E. with or without the addition of silicone compounds, or a resin bonded paper laminate. The lining may be protected by an addition of silicones to its outer surface. The temperature of roller 4 is maintained close to that of the sheet F by fluid flow in channels (8), Fig. 2 (not shown), and/or internal electrical heaters, or by heating the surface of the lining, e.g. with infrared lamps. In a second embodiment, Fig. 3 (not shown), lined roller (10) is situated between smooth or patterned steel rollers (12, 13) which are preferably heated to a temperature slightly below that of roller (10). In modifications, a second lined roller may be used, e.g. roller (13), to give sheet F a matt surface on both sides and a pair of rollers may be situated upstream or downstream of the lined roller to size the sheet.

Title: Starting box for dog racing
IPC: A63K3/02
Filed: 1927-06-17
Abstract: 293,961. Cooper, J. N. June 17, 1927. Dog-racing apparatus.-A starting box, for use in dog racing, comprises a box divided into compartments each provided at the front with a shutter or window slidable in vertical guides, means for retaining the shutters in their lowered positions in opposition to the action of raising means, and means for actuating the retaining means to release the respective shutters at predetermined times and permit them to be opened by the raising means. Each shutter or window 8 is urged in a vertical direction by springs 13, 14 and is retained in its lowermost position by a catch secured to the top of the compartment. A shaft 19 rotated by a spring mechanism 22, or by a handle applied to the end 19<a>, carries a number of cams 18 which engage the catches and thereby prevent the opening of the gates when these are in their closed positions. When the shaft is rotated the cams liberate the catches at predetermined. intervals, or simultaneously, according to the setting of the cams, and the shutters are opened by their springs at corresponding intervals. To permit of variation in the relative moments of opening of the shutters, the angular setting of the cams 18 upon the shaft. 19 may be adjusted by means of notches 23, Fig. 5. on the cams end pins 24 on the shaft. Rubber buffers 15 cushion the rise of the shutters. The Provisional Specification also describes an arrangement wherein the release of the catches is effected by the impact of balls arranged to run down guides of various lengths or inclinations.

Title: Perfluoroalkyl alkanols
Inventor: AHLBRECHT ARTHUR H
IPC: C08F20/24
Filed: 1958-08-11
Abstract: The invention comprises the compounds Rf(CH2)mOH, where Rf is a perfluoroalkyl radical having 3-12 carbon atoms and m is 3-12.  These compounds may be prepared by the desulphonylative addition of a perfluoroalkane sulphonyl halide to a terminally unsaturated alcohol, esterified alcohol, or carboxylic acid, followed by reductive dehalogenation to replace halogen by chlorine, and hydrolysis if an esterified alcohol was used or reduction if an acid was used.  In Examples, (1) C8F17SO2Cl is reacted with 4-pentenoic acid to give 4-chloro-5-(perfluorooctyl)-pentanoic acid, which is hydrogenated to 5-perfluorooctyl pentanoic acid, and this is reduced to 5-perfluorooctyl-pentanol; (2) C8F17SO2Cl is reacted with alkyl acetate to give 2-chloro-3-(perfluorooctyl) propyl acetate, which is dehydrohalogenated to 3-(perfluorooctyl) alkyl alcohol, and this is reduced to 3-(perfluorooctyl) propanol; (3) ethyl perfluorobutyrate is condensed with methyl acetate to give C3F7COCH2COOCH3, this is reduced to C3F7CHOHCH2COOCH3, which is dehydrated to C3F7CH:CHCOOCH3; this is hydrogenated to the saturated ester, which is reduced to C3F7(CH2)3OH.
Patent GB-766685-A (GB)
Title: Improvements in or relating to process for the recovery of glutamic acid
Filed: 1954-06-02
Abstract: Glutamic acid is obtained by hydrolysing precursors thereof, neutralizing the hydrolysate with an agent which forms an insoluble salt with the hydrolytic agent, separating off the salt, adjusting the pH of the filtrate to 2.5-4.0 with sulphuric acid, crystallizing out glutamic acid, adjusting the pH of the mother liquor to 1.0-3.5 with sulphuric acid, adding sufficient methanol to precipitate ash-forming material and crystallizing glutamic acid from the filtrate at its isoelectric point.  The latter step is facilitated by passing the solution through a cation or anion exchanger, subsequently eluting the adsorbed glutamic acid and crystallizing it at pH 2.5-4.0.  The process is applicable to the treatment of desugarized beet molasses or proteinaceous materials such as gluten. Hydrolysis may be effected with barium or calcium hydroxide and the metal subsequently precipitated at pH 6-10, preferably 7-10, with carbon dioxide, sulphur dioxide (or salts thereof) or sulphuric acid. It is advantageous to bring the pH first to 4.5-5.5 and concentrate and filter the solution before the final adjustment of the pH.  An example is given of the process.  Specifications 655,841, 742,497 and U.S.A. Specification 2,586,295 are referred to.  Reference has been directed by the Comptroller to Specification 644,382.
