Patent GB-801730-A (GB)
Title: Improvements in and relating to the extraction of chlorine from gaseous mixtures
IPC: B01D53/68
Filed: 1956-06-22
Abstract: Chlorine is purified by absorption in and desorption from chlorosulphonic acid.  The chlorine treated may be 98-99 per cent pure chlorine obtained by electrolysis, or may be contaminated with volatile chlorinated carbon compounds, e.g. phosgene.  In the latter case the chlorine may be separated from the volatile chlorinated carbon compounds, which are also absorbed, by fractional desorption. The absorption and desorption apparatus may each comprise one tower or a plurality of towers in series or parallel.  A solubility table is given for temperatures within the range of -30-20 DEG  C. and pressures within the range of 100-760 mm.  Atmospheric temperature or a temperature of 0 DEG  C. and a pressure of 2.5 kg. absolute may for example be used in the absorption stage.  The conditions of pressure and temperature in the desorption stage are preferably such that the gaseous chlorine evolved may be liquefied at atmospheric or cooling water temperature.  A temperature of 80-100 DEG  C. and a pressure of 2.5 ks. absolute may for example be used in the desorption stage. Before liquefaction the chlorine may be refluxed with liquid chlorine product.  The pressure of the degassed solvent may be reduced to that of the absorption stage or to atmospheric pressure with further evolution of chlorine.  The resulting solvent and further desorbed chlorine may be separately cooled and returned to the absorption stage.  The residual gases from the absorption stage may be freed from traces of chlorosulphonic acid by washing with 90-97 per cent sulphuric acid followed by an aqueous alkaline solution or water.

Title: Improved method of and means for producing knitted eyelet fabric
Inventor: JACKSON ARTHUR THOMAS DOUGLAS
IPC: D04B9/38
Filed: 1958-06-20
Abstract: 865,363. Knitting. MELLOR BROMLEY & CO. Ltd. June 3, 1959 [June 20, 1958], No, 19820/58. Class 74 (2). Pelerine instruments are provided in a multifeeder circular machine so that there is a pair of such instruments capable of projecting in the space between each needle and the next. By manipulating the instruments each needle receives opposite-hand portions of each adjacent sinker loop in alternate courses whereby square mesh eyelet fabric is produced. As described in connection with a two feeder machine having a needle carrying dial, a tricked cylinder concentrically mounted beneath the dial carries pelerine instruments 14, 15 associated in pairs the ends of which are projected between adjacent needles in the dial as the needles approach the first feeding station F<SP>1</SP>, Fig. 1A. Each pelerine instrument has a yarn engaging hook to engage the sinker loop but whereas the instrument 14 is laterally bowed to provide a loop expanding portion 16, the instrument 15 is wholly straight. At the first feeder all of the needles draw the yarn Y<SP>1</SP> about the ends of the instruments whereas at the second feeder the yarn Y<SP>2</SP> is fed to the needles behind the instruments. After drawing and knitting the yarn Y2 the needles are again advanced simultaneously as the pelerine instruments are advanced in the loop transfer station A where the laterally bowed portion 16 of pelerine instrument 14 spreads that half of its sinker loop formed from yarn Y<SP>1</SP> as to cause the needle on the left-hand side of it, as illustrated in Fig. 1B, to project beneath and receive it. Thereafter the needles are retracted and the pelerine instruments 14 withdrawn leaving the straight instruments 15 still projecting and in engagement with the other half of the sinker loop. As the instruments and needles progress they pass into a second loop transfer station B where the ends of the instruments 15 engage a deflector cam 23 such that these instruments are bent to one side whereby the needle normally on the right-hand side of each instrument now passes the instrument on its left-hand side, as shown in Fig. 1B, and receives the other half of the sinker loop formed from the yarn Y<SP>1</SP>. Thereafter the instruments and needles are withdrawn and the two feeder cycle followed by the two separate loop transfer operations repeated. The effect produced is illustrated in Fig. 5 whereby every sinker loop S of every alternate course is spread over both adjacent needles to produce square mesh eyelet fabric.

Title: Improvements in and relating to casting pattern compositions
IPC: B22C7/02
Filed: 1944-10-18
Abstract: A composition for use in making patterns for moulds for casting metal consists of a mixture of a waxy material, a rubber-like hydrocarbon, and a resin, so that after formation of the mould the composition can be removed by heating.  The composition melts between 70 and 80 DEG C., and does not separate into its constituents on melting.  The hydrocarbon may be balata or chicle and is present in an amount not exceeding 25 per cent., and preferably about 10 per cent. of the composition.  The waxy ingredients and the resin, e.g., cumar or indene resin, which serves as a fluxing-agent, are melted together, the balata &c., preferably comminuted, is stirred in, and the composition is then forced into the pattern in a vacuum, pressure being then applied to eliminate cavities.  It is then used as a pattern for the formation of a mould (see Group XXII).  According to examples, the composition may comprise mixtures of (1) a hard wax such as vegetable fibre wax, a softer wax such as candelilla, a hydrogenated vegetable oil such as hydrogenated cotton seed oil, a petroleum wax, balata, and cumar resin; (2) hydrogenated castor oil, hydrogenated cotton seed oil, petroleum wax, cumar, and balata; (3) vegetable fibre wax, candelilla, paraffin wax, and chicle.

Abstract: 1,065,382. Lasers. COMPAGNIE GENERALE D'ELECTRICITE. May 14, 1964 [May 17, 1963], No. 20213/64. Heading H1C. The output of a laser element (R), Fig. 6 (not shown), in a resonant cavity, formed by two parallel mirrors (M1, M2), is controlled by an electro-optical device (A) which normally acts as a plate having parallel surfaces, but whose refractive index can be varied by an electric field gradient across the width of the plate to deviate the radiation passing through it. Resonance is therefore prevented. Device (A) consists of one or more plates of ADP, KDP or deuterium, substituted KDP, the or each plate having an electrode on each major surface. The electrodes are placed near one side of the plate so that the field strength decreases across the width of the plate, with a corresponding decrease of refractive index. Radiation passing through the plate is deviated in one direction or another depending on its plane of polarization. When several plates are arranged in series adjacent plates are displaced through 90 degrees to prevent deviation in one plate being reversed by passage through the oppositely biased adjacent plate.
