Patent GB-728363-A (GB)
Title: Improvements relating to apparatus for controlling the supply of fuel and air to combustion chambers
IPC: F23N1/02
Filed: 1952-06-12
Abstract: 728,363. Automatic control systems for boilers. BOUILLON, F. A. Sept. 14, 1953 [June 12, 1952], No. 14887/52. Class 38 (4). In an automatic control system for maintaining optimum furnace conditions in a steam boiler, the fuel and air supplies are controlled by photo-electric cells in accordance with the brightness of the fuel bed and the opacity of the flue gases. The series connected cells 5 respond to the furnace brightness, and the cell 6 to a beam of light projected through the flue gases. All cells are of the type in which the resistance increases with the incident light, and control the output of a gas-filled triode, Fig. 3 (not shown), which energizes two banks of relays 4, 11 controlling the armature currents of the fuel feed motor 2 and the fan motor 3. A decrease in brightness, or an increase in gas opacity increases the output voltage of the valve and relays 4, 11 pick up sequentially to increase the speeds of the motors. The motor 2 is controlled in four steps, the motor 3 in eight half steps. A contact making manometer responsive to boiler pressure energizes relay 33 to shut down both motors should the pressure become excessive.

Title: Method of separating methanol from a mixture thereof with water, xylene and esters
IPC: F16K31/60
Filed: 1962-04-17
Abstract: 961,075. Separation of methyl toluate from reaction-mixtures. CALIFORNIA RESEARCH CORPORATION. April 17, 1962 [April 27, 1961], No. 14919/62. Heading BIB. A mixture of methanol, water, methyl toluate and xylene is separated into three fractions, namely anhydrous methanol, water, and a mixture of methyl toluate and xylene, by a continuous process using a fractional distillation column and a gravity separator. The initial mixture is fed to the column 1 at the point B, and undergoes fractional distillation to produce a distillate of anhydrous methanol at the top of the column. The liquid at the point C in the column is passed into a gravity separator 2, where it separates into an aromatic enriched phase and a water enriched phase, the former phase being returned to the column at the point D and the latter phase being rejected. A mixture of methyl toluate and xylene is withdrawn from the base of the column. The temperature inside the column at the point A is maintained between 155 ‹F. and 210 ‹F., and a minimum weight ratio of xylene to methanol of 1: 50 is maintained in the feed mixture, in order to obtain an efficient separation of the mixture. This method of separation finds use in the treatment of the by-products formed during the preparation of dimethyl esters of phthalic acid by the oxidation of xylene followed by esterification of the oxidation product with methanol.
Patent GB-595403-A (GB)
Title: Production of filaments from viscose having the capacity to crinkle
IPC: D01F2/06
Filed: 1944-08-08
Abstract: Artificial filaments having the capacity to crinkle when treated with water are made by forming a viscose solution having from 7 to 13 per cent of cellulose and from 7 to 13 per cent of caustic soda with a cellulose to caustic soda ratio of about 1, i.e. between 0.8 and 1.2, extruding into an acid spinning bath to form coagulated and regenerated cellulose filaments and subjecting the filaments to stretching at a tension of more than 0.25 gram per denier and preferably at as high a tension as possible without injury to the filaments.  The filaments may be dried without appreciable shrinkage and thereafter washed with water or with a solution of a swelling agent, e.g. a 50 per cent aqueous solution of potassium iodide to produce the crinkle.  Preferably, the viscose used has a salt point of from 4.0 to 7.5.  Filaments with potentiality to crinkle when washed with water may be preserved in the straight state without mechanical stress by taking them directly from the spinning machine and washing free from acid with a 45 per cent aqueous solution of ammonium acetate.  Crinkled filaments may be obtained having a filament denier of 1 to 7 or even lower and a strength of more than 3 grams per denier and an elongation of about 20 per cent in the fibre itself.  In examples: (1) viscose with a composition of 10 per cent each of cellulose and caustic soda, and a salt index of 5.8 is spun into a common spin bath, and the filaments are stretched under a tension of 200 grams for 200 deniers, collected in a centrifugal pot, skeined and placed in water, whereupon they become crinkled; (2) viscose having 9 per cent each of cellulose and caustic soda at a salt index of 5.5 is spun into an acid bath and the filaments drawn at a tension of 350 grams for 400 deniers, cut into staples and placed in water; and (3) viscose having 10 per cent cellulose and 9 per cent caustic soda and a salt index of 6 is spun into an acid bath and the filaments stretched at a tension of 190 grams for 200 deniers with progressively increasing tension while in the spin bath, skeined and washed.

Title: Improvements in or relating to sterilizers for liquids
IPC: A61L2/24
Filed: 1933-05-26
Abstract: 420,301. Fluid - actuated valves. GREVILLE, E. G., and HICKMAN, F. C., 167, Gray's Inn Road, London. May 25, 1933, No. 15281. [Class 135] Liquid supply means for a sterilizing or other vessel 1 includes a controlling element 19 for the filling opening 7 of the vessel which is operable under pressure of the liquid supplied, being moved into a position to permit the flow of the liquid into the vessel when the supply cock is opened, and when this cock is closed moving into a position in which it prevents ingress to the filling opening 7 of any liquid entrapped or leaking past the supply cock, such liquid discharging through an overflow outlet 5, contamination of the,liquid in vessel 1 being thereby prevented. As shown, a valve casing 2 is screwed into the inlet 8 at the top of a sterilizer 1 for water, and has a water inlet 4 connected to the main. The water passes from inlet 4 to the opening 7 through a cylinder 9, a pipe 16, a spout 17 and a space 28 enclosed by an annular wall 27. The inlet opening 7 is closed by a check valve 19 which rests on a seating 20 and has fins 21 and is combined with a hemispherical deflector 22 which when the valve is closed on seating 20 deflects drip to the outside of wall 27 whence it passes to outlet 5. The deflector 22 and valve 19 are actuated by a piston 10 sliding in cylinder 9 and connected by a rod 18 and a pin and slot connection 25, 26 to the valve 19. When the supply cock is opened, the water pressure forces the piston 10 upwards and the valve 19 is opened thereby and the deflector 22 drawn up into inoperative position. The cylinder 9 has a slot 13 to release water trapped above the piston 10. The pin and slot connection 25, 26 permits the valve 19 to rise independently and act as a safety valve under undue pressure in the vessel 1. The valve 19 may be returned to its seating by a spring.

A conductor manipulating tool comprises a pair of dies co-operating with each other to form a die aperture of a non- circular form corresponding to that of a bared or insulated conductor to be bent and/or twisted by means of the tool, a housing in which the dies are mounted in such a way that the cable conductor has access to the die aperture, an operating handle for the tool projecting from the housing, and means formed by or carried by the operating handle for causing relative movement of the dies one towards the other to clamp the bared or insulated conductor between the two dies. A solid sector shaped conductor of a three cored cable is passed through apertures 4 in the wall of a tubular housing I between a pair of dies 2, 3 which cooperate to form a sector shaped die aperture. The conductor is then clamped between the dies by moving the die 3 towards the die 2. This is effected by turning a rod 14 threaded in a plug 12 on one end of the housing 1 and engaging the die 3. The rod 14 is formed with a tubular handle 18 surrounding the protruding end of the rod 14 and part of a tubular extension 13 of the plug 12. Alternatively the rod 14 may constitute the handle. A conductor held by two tools is bent and/or twisted by relative movement of the tools to bring the conductor into a suitable position for making a required ferruled joint.
