Title: Improvements in and relating to hydraulic systems and control valves therefor
Inventor: TOWLER JOHN MAURICE
IPC: F16K11/076
Filed: 1952-03-15
Abstract: 727,804. Valves. ELECTRAULIC PRESSES, Ltd. Feb. 27, 1953 [March 15, 1952], No. 6762/52. Class 135. A rotary disc valve for distributing pressure liquid to a plurality of valves, each of which controls a separate hydraulic apparatus, comprises a rotary disc 1, Fig. 1, keyed to an operating spindle 4 and enclosed in a three-part valve body 2, 3, 2a. The disc 1 has two concentric rows of axial bores 101 ... 105 and radial bores 11 connecting axial bores on the same radius with an annular space 32 surrounding the disc. On rotation of the disc, an inlet connection E may be brought into communication with outlet connections A, B, C, D, Fig. 2, either individually or jointly to supply pressure liquid in a predetermined sequence to servooperated control valves controlling pumps having capacities in the ratio of 1, 2, 4 and 8 respectively, so that the combined capacity of the pumps may be varied in arithmetical progression from 1 to 15. The arrangement is such that when the axial bore 101 registers with the outlet A, the pump having capacity 1 <SP>"</SP> is loaded, all the others remaining unloaded. Clockwise rotation of the disc brings the axial bore 102 into register with the outlet B to load the pump of capacity 2 and unload the pump of capacity 1. Further clockwise rotation of the disc brings axial bores 103, 104 into register with outlets A and B respectively to give a joint capacity of 3 and so on up to a maximum capacity of 15 when all the outlets are connected to the inlet E. To pressure balance the disc a radial bore 12 and an axial bore 14 connect the space 32 with recesses 13 on either side of the disc, and blind bores 23 are formed in the body part 2 opposite to the outlets A, B, C and D in the body part 2a. A spring-loaded ball 83 engages in notches 19 on the periphery of the disc to locate the disc in each of its positions and a graduated dial 6 co-operates with a pointer on a fixed plate 7 to indicate the pump capacity being supplied.

Title: Improvements in electric switches with liquid immersed contacts
IPC: H01H33/22
Filed: 1932-03-09
Abstract: 382,193. High-tension switches. SIEMENS - SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. March 9, 1932, No. 7056. Convention date, April 16, 1931. [Class 38 (v).] Instead of using inflammable mineral oil for oil switches and " expansion " switches fluorinated hydrocarbon compounds are employed. Examples of such compounds are fluoronaphthalene and trifluorotoluene. They may be produced by passing fluorine into insulating oil until the fluorine content amounts to about 50 per cent. Fluorinated hydrocarbon compounds which in addition to the fluorine contain another halogen or more than one other halogen at the same time may be employed. Mixed-halogenated hydrocarbons which also contain the nitro group such as nitrochlorofluorotoluene may be used. A 5 or 10 per cent addition of the fluorinated hydrocarbons to an inflammable oil may be adequate.

Filed: 1967-02-15
Abstract: 1,173,340. Fructose; addition compounds thereof. K. HARA, and T. BABA. 15 Feb., 1967 [16 Feb., 1966], No. 7217/67. Heading C2C. Fructose is separated from mixtures thereof with glucose and/or other mono- or di-saccharides by two processes, (A) when in an anhydrous mixture with glucose, by treating the mixture with anhydrous ethanol containing anhydrous CaCl 2 , the amount of ethanol being at least 5 times the estimated weight of fructose in the mixture and the amount of CaCl 2  being at least 60% by wt. the estimated amount of fructose, whereby an ethanol-soluble addition compound of fructose is formed and undissolved glucose is filtered off, or (B) when in an aqueous solution with other mono- or di-saccharides, by adding 15-100% by wt., based on estimated amount of fructose, of anhydrous CaCl 2  or SrCl 2  to the solution and then adding sufficient anhydrous or substantially anhydrous ethanol to the solution to bring the aqueous content thereof into the range 5-30% by vol., based on total volume of solvent, whereby the addition compound of fructose and CaCl 2  or SrCl 2  is precipitated, if necessary after seeding with crystals of the addition compound, recovering the addition compound by filtration, washing with 85% by vol. ethanol and drying. In process (B), ethanol can be replaced by an ethanol/ methanol mixture containing no more than 50% by vol. methanol. The fructose/CaCl 2  addition compound may be precipitated from the ethanol solution obtained by process (A) by adding sufficient water thereto to bring the aqueous content to 5-30% by vol., based on total volume. It is preferred to effect all the above processes at 10-25 C. Fructose may be liberated from the addition compound with CaCl 2  or SrCl 2  by dissolving the precipitates obtained by the above processes in an approximately equal amount by wt. of water and removing CaCl 2  or SrCl 2  by ion-exchange treatment or by adding an alkali metal sulphate to precipitate CaSO 4  or SrSO 4  and, after filtering, concentrating the aqueous fructose solution. Examples describe the separation of fructose from glucose and from invert sugar.

Patent GB-617089-A (GB)
Title: Improvements in or relating to apparatus for determining the vapor content of a gas
IPC: G01N25/68
Filed: 1946-03-08
Abstract: Apparatus for determining the vapour content of a gas comprises a light-reflecting surface adapted to be cooled by the expansion of a gaseous refrigerant fluid in heat conducting relationship therewith and means for passing gas to be tested over the surface in out-of-contact relationship with the fluid to cause vapour to condense on the surface so that a beam of light projected against the surface at an acute angle thereto has at least a portion thereof scattered or deflected from its normal path by the condensed vapour to afford a visual indication of the vapour content.  A light-reflecting surface 33 is provided on a target 19 made of copper.  The target is provided with a gas-tight cavity which is con <PICT:0617089/III/1> nected by tubing 17 to a thermometer 18 and with another cavity which is fed with refrigerant gas (e.g. carbon dioxide) which passes from a tube 42 up through a central bore in a tube 16, through an expansion nozzle into the cavity, and down through an annular passage in the tube 16 to leave via a line 41. Thermal insulation is provided between the central bore and the annular passage.  A light source 30 project rays through a transparent window 14 on to a smooth light-reflecting conical surface 13 from which they are reflected on to the surface 33 at an acute angle which thus appears dark when viewed through a lens system 24, 25. The deposition of dew or front from a gas under test entering through line 20 and leaving through a line 28 scatters the light, making it visible through the lens system.  The thermometer fluid in the tube 17 and thermometer 18 may be a liquid such as mercury or toluene or a gas such as carbon dioxide, "Freon" (Registered Trade Mark), methyl chloride or sulphur dioxide.  The gaseous refrigerant may alternatively be ammonia, sulphur dioxide or "Freon."  According to a modification, visual observation is replaced by a photo-tube or like light-sensitive device coupled through a standard amplifier to a recording or indicated instrument.

Patent GB-443314-A (GB)
Title: Process for the recovery of sulphur dioxide from gases containing same
IPC: C01B17/60
Filed: 1935-03-08
Abstract: In the recovery of sulphur dioxide from gases by washing them with a mixture of organic bases and water, and thereafter heating the reaction product, there is added to the circulating absorption liquor, either before, during or after the absorption step, compounds of alkaline-earth metals, which precipitate in the form of sparingly soluble alkaline-earth sulphates, the sulphuric acid formed by secondary reactions (e.g. the oxidation produced by the oxygen present and the autoxidation of the sulphur dioxide).  The troublesome formation of sulphates of organic bases is thereby avoided and the separation of the aqueous liquid from the organic liquid is facilitated.  In addition, the effluent gas from the absorption treatment and/or the sulphur dioxide recovered in the heating step may be treated with the above compounds in the presence of water, the organic base content of these gases being thereby recovered; the liquors thus obtained may be used in the main process. The oxides, hydroxides, carbonates, neutral and acid sulphites and other weak acid salts of the alkaline-earth metals, (e.g. calcium) may be employed in the process.  Suitable organic bases include aniline and its homologues, toluidines, xylidines, compounds of the above kind alkylated in the amine group, pyridine, pyridine bases, quinoline, triethanolamine, hydroxylamines and hydrazines.  As regards details, the process may be conducted in the manner described in the parent Specification.  The presence of elementary sulphur or substances furnishing it under the conditions of working, e.g. sulphides of alkaline-earth metals or barium hydroxide obtained by reducing barium sulphate and containing sulphide, should be avoided since sulphur catalytically accelerates the autoxidation of sulphur dioxide.

Title: Improvements in or relating to the production of carbon disulphide and hydrogen sulphide
Inventor: BANKS ARTHUR ASHTON
Filed: 1959-03-06
Abstract: Carbon disulphide and by-product hydrogen sulphide are prepared by reacting a preheated vaporized hydrocarbon feed which is liquid at ambient temperature, which is substantially completely vaporized at a temperature below 200 DEG  C., and which consists predominantly of hydrocarbons having at least 5 C atoms in the molecule with sulphur vapour, without premixing of reactants, in a zone substantially completely occupied by a catalyst, said zone being maintained at 700 DEG  to 1300 DEG  C. as described in the parent Specification, and thereafter continuing the reaction in a non-catalytic zone contiguous with the catalytic zone, the non-catalytic zone also being maintained at 700-1300 DEG  C.  The hydrocarbon feed may be aliphatic, alicyclic, or aromatic, preferably consisting predominantly of hydrocarbons having at least 6 C atoms/molecule. The reaction may be effected under substantially atmospheric pressure with the temperature in the catalytic zone being 700 DEG  to 900 DEG  C., and that in the non-catalytic zone being 900 DEG  to 1100 DEG  C. The reaction may be effected in a silica tube with one end packed with potassium vanadate on silica catalyst.  The remainder of the tube being empty and forming the non-catalytic reaction zone.  A stoichiometric excess of sulphur may be used, and the hydrocarbon feed may be diluted with an inert gas, e.g. nitrogen.  Gases leaving the reaction zone are cooled to condense sulphur which is recycled, further cooled or washed with light oil to isolate carbon disulphide, and washed with aliphatic amine to isolate hydrogen sulphide. Hydrogen sulphide after recovery from the amine may be converted to sulphur by the Claus process, such sulphur being recycled, or may be employed as such, for example, in the manufacture of sodium sulphide. Specifications 798,947 and 939,209 also are referred to.
