Patent GB-422689-A (GB)
Title: Process for the joint production of a caustic soda lye, poor in sodium chloride, and of glauber salt
IPC: C01D1/04
Filed: 1934-07-16
Abstract: Caustic soda lye poor in sodium chloride, and Glauber's salt are produced simultaneously by treating crude brine with sodium carbonate to precipitate calcium and magnesium, electrolyzing the brine containing sodium sulphate, concentrating the resultant caustic soda lye to deposit sodium chloride containing sulphate which is washed to remove the sodium sulphate and the solution concentrated and cooled to deposit Glauber's salt.  The washed sodium chloride is returned to the electrolysis together with the Glauber's salt mother liquor. Part of the Glauber's salt is reacted with warm concentrated caustic soda lye to form a triple salt containing NaCl, Na2SO4 and NaOH which is precipitated, leaving a lye poor in chloride.  This triple salt is dissolved in water and Glauber's salt, which can be re-used in the process, deposited by freezing, the resultant solution being treated with carbon dioxide or gases containing the same to yield a sodium carbonate solution used for purifying the brine.

Title: Improvements relating to mechanism of saxophones
IPC: G10D7/08
Filed: 1925-08-21
Abstract: 261,482. Macdonald, C. S. Aug. 21, 1925. Saxophones, &c. - The tampions 47, 1, 2, 3, Fig. 2, respectively of top F, E, Eb, and D form the upper part of a group of successive, notes in which the opening of one vent opens all the lower vents of this part of the group. Tampion 3 (D) is sprung to open but is normally held closed by a stronger spring under an arm 22, which arm may however be depressed either by a key 23 or by tampion 13 to permit D to be sounded. Tampion 2 (Eb) is opened by a key 17 which, acting on the arm 22 simultaneously opens tampion 3. Tampion 1 (E) is opened by a key 16 and lever 50, which lever opens also tampion 2, and therefore also tampion 3. Tampion 47 (F) is opened by a key 49, which by an arm 51 operates lever 50 and opens tampions 1 and 2, and therefore also tampion 3. When, in the other part of the group, either the open tampion 4 is closed (by either key 35 or key 5 and bar 33), or tampion 5 (by key 36), or tampion 6 (by key 6<a>, or by key 35, or by tampions 12 or 11 by means of bar 42a, tampion 10, arm 40 and bar 38), or tampion 7 (by key 35), a lever 44 is operated to close tampion 3 if open. In another construction, in lieu of direct operation by tampion 13 which then acts like the tampions 12, 11, the tampion 3 may be permitted to open by depressing a key which is situated between tampions 13, 12 but may however project under tampion 13; tampion 2 may alternatively be opened by a right-hand key situated near key 16 by a slight modification of the lever 50; tampion 47 (F) is omitted; and lever 44 projects instead under arms on bar 33 and tampion 6, of which arms slight variations are shown. Fig. 5 shows a modified control of tampions 3, 2 operation of key 23 permitting tampion 3 to open alone by the removal of an arm 57, and operation of key 17 opening tampion 2 and by an arm 56 permitting tampion 3 to open simultaneously. In other modifications, the tampions 47, 1, 2 - - 6 are arranged in a straight line.

Title: Collasen tubing
Inventor: TAYLOR KENNETH WILLIAM
IPC: B29C48/09
Filed: 1968-05-06
Abstract: 1,220,124. Tubular collagen films. UNILEVER Ltd. 30 April, 1969 [6 May, 1968], No. 21291/68. Heading B5B. Tubular collagen films suitable for use as sausage skins are produced as shown in Fig. 1 by extruding a collagen dough from the contrarotating cone extrusion nozzle 2 into a coagulating bath of saturated brine which is circulated both inside and outside the film, the diameter of the film being controlled by monitoring the pressure differential between the inner and outer surfaces of the film and keeping this constant by automatically adjusting the rate of introduction of brine through tube 7, through tube 8 or both, i.e. by adjusting the head of brine inside the film. As shown in Fig. 1, brine from the supply tank 18 is supplied to the tank 1 via the tube 4 and is returned to tank 18 via the overflow 5 which serves to keep the level in tank 1 constant and at the same time the tube is inflated above the surface of the brine within it by means of air introduced via tube 9. In order to monitor the pressure differential across the inner and outer surfaces of the film, the differential pressure amplifier cell 13 is connected via dirt traps 12 to the take-off points 10 and 11 and is used to operate a brine flow control 14, which activates valve 15 in the line 16 supplying tube 7. A more accurate modification of the monitoring and control apparatus having a shorter response time is also given (Fig. 2, not reproduced). The head of brine within the tube may be controlled not only by the rate at which brine is supplied to tube 7 but may also be controlled by the rate at which brine is withdrawn via tube 8 or by both. Also in some cases the pressure dependence of the diameter may be variable in which case the pressure differential itself can automatically be varied by monitoring the diameter of the film.

Patent GB-1014107-A (GB)
Title: An improved process for the production of alkyl- and cycloalkyl sulphonates
Filed: 1963-05-30
Abstract: Alkyl or cycloalkyl sulphonates are prepared by the partial sulphochlorination of aliphatic or cycloaliphatic hydrocarbons, saponification of the resultant sulphochlorides, and evaporation of the sulphonate solution to which 0.2-2% by weight of alkali metal sulphite, thiosulphate or dithionite has been added.  The addition of these salts prevents the formation of coloured impurities during the high temperature evaporation of the aqueous sulphonate solution.  The amount of salt added is dependent upon the composition of the hydrocarbons used, the chlorine content of the sulphonate, and the conditions during evaporation.  Generally, 0.2-1% is sufficient for sulphonates produced from aliphatic hydrocarbons, and 0.5-2% for sulphonates from cycloaliphatic hydrocarbons. Excess of sulphate, thiosulphate or dithionite is removed by treatment with an oxidizing agent, preferably sodium hypochlorite solution.

Abstract: 1389914 Lithium niobate single crystal WESTERN ELECTRIC CO Inc 10 May 1972 [12 May 1971] 21718/72 Heading C1A [Also in Divisions C7 and H1] A process for the preparation of a single crystal of (Li 2 O) 0À44-0À5 (Nb 2 O 5 ) 0À5-0À56 which may be doped with other substances (e.g. magnesium) up to 1% of the cation content characterized in that a melt thereof is prepared in a furnace such that the iron content of the melt and of the melt container is no more than 1 p.p.m. based on the total cationic content and the iron content of the other material in the melt furnace zone is no more than 10 p.p.m. and that the crystal so prepared is not contaminated with more than 10 p.p.m. iron during any further processing. The low iron content of the melt and furnace material may be obtained by avoiding contact of the melt ingredients with material of total iron content greater than 10 p.p.m., e.g. by grinding the melt ingredients using agate abrading surfaces and by the use of silica or high purity magnesia furnace support members. The melt may be formed from ground and sintered lithium niobate or may be produced by heating the initial melt ingredients together within the furnace. The crystalline material prepared may be annealed in an oxidizing atmosphere at 500-700 C. for at least 30 minutes or for at least 5 minutes in the presence of an electric field of current density at least 1 milliamp per sq. cm. cross-section. The so formed crystals is of reduced susceptibility to radiation damage in comparison with conventionally prepared crystals and may be utilizied in electrooptic or acousto-optic devices, e.g. S.H.G., oscillators, modifiers and mixers.

Abstract: Textile materials, films and the like are delustred and weighted by water-insoluble nonresinous condensation products derived from an aldehyde and urea, ammonium cyanate, thiourea, cyanamide or the like, the insoluble material being employed in the form of an already finely-divided material.  The finely-divided material may be added to a cellulose or cellulose derivative spinning solution, or the material, prepared in the presence of a dispersing agent which is not a solvent for the material, may be added to a spinning solution or applied to the textile or like materials.  Fixing agents, such as natural or synthetic rubber latices, resins, intermediate condensation products or salt of de-acetylated chitin, may be employed.  In an example, there is added to a viscose spinning solution or to a cellulose acetate film-forming solution a dispersion obtained by treating a solution of monomethylol urea with tartaric acid in the presence of the sodium salt of sulphonated lauryl alcohol.  In p  another example, methylene urea precipitated from solution in hydrochloric acid, is added to viscose spinning solution. In a further example ground methylene urea is added to a viscose spinning solution.  An example is given also of the treatment of a textile material with a dispersion of methylene urea made in the presence of the sodium salt of sulphonated lauryl alcohol.  In a further example, tartaric acid or hydrochloric acid is added to a solution containing urea, formaldehyde and a fatty alcohol pyridinium halide, and the white dispersion applied to a textile material. Another example is given in which a mixture of a dispersion of methylene urea and a condensation product obtained by reacting urea with formaldehyde in the presence of ammonia, is applied to a fabric which is then heated.  Specification 467,480 is referred to.
