Title: Improvements in or relating to the manufacture of articles of rubber and similar substances from aqueous dispersions containing such substances
IPC: C09D5/44
Filed: 1929-02-07
Abstract: 331,563. Dunlop Rubber Co., Ltd., Twiss, D. F., and James, R. G. Feb. 7, 1929. Addition to 301,100. Emulsions, making.-In a dispersion of rubber or other organic material the particles of which normally carry a negative charge, the hydrogen ion concentration is increased in the presence of suitable protective colloids to such a degree that the charge on the particles is reversed without coagulation occurring. The hydrogen ion concentration may be one corresponding to a pH value between 5 and 0. Suitable protective colloids are casein, haemoglobin, saponin, egg albumen and similar proteids, gelatine and liquorice. Sodium methylene naphthalene' sulphonate and similar complex sulphonates are not effective. In an example 100 c.c. of latex free from ammonia containing 60 per cent rubber is diluted with 120 c.c. of a faintly alkaline 1 per cent solution of casein. A mixture of 50 c.c. glacial acetic acid and 50 c.c. water is then added, bringing the pH value of the latex to 2.7. Formic acid may be used as acidifying agent. The aqueous dispersion may be of rubber, guttapercha, balata or analogous vegetable resins and may contain vulcanizing and compounding ingredients and may be in a preserved or concentrated state, and may be natural or artificial, or obtained from rubber reclaim or synthetic rubber. A sulphur dispersion the particles of which travel to the cathode may be incorporated with the rubber dispersion. When ammonia-preserved latex is employed it may be aerated to reduce the ammonia-content before increasing the hydrogen ion concentration. It may also be diluted before or after aeration.

Title: Improvements in a process and apparatus for maintaining a uniform pulp supply to machines
IPC: D21J5/00
Filed: 1926-02-13
Abstract: 270,431. Hall, R. E. Feb. 13, 1926. Pulp, regulating flow and consistency of. - In apparatus for the automatic regulation of the consistency of fibrous pulp in the production of articles of uniform weight and density when dry, applicable to the process described in Specification 253,179, wherein the pulp is deposited on formers dipped into a felting tank, the primary supply of pulp in a tank 1 is discharged through a valve 10 to a mixing tank 11 wherein a water supply pipe 17 having a float-controlled valve admits regulated quantities of water. The pulp from the tank flows through pipe 12 to a felting tank 13 provided with a pump 14 for circulating the pulp between the tanks 11, 13. The formers within the tank 13 extract a certain amount of water and pulp, and the drop in level is made good by the water supply pipe 17. Periodically the regulated quantity of pulp from the tank 1 is admitted to the tank 11, the valve 10 therefor being operated by a hooked rod 29, Fig. 4, engaging studs in the ends of rotating arms 25. Mounted on one or more of these arms are plates 26 carrying projecting pins 27, 28 which engage a star wheel 24 on the stem of the valve 10 to open and close the valve. The level of stock in the tank 1 is adjusted by the setting of a hinged overflow pipe 6 discharging into a trough 8. In operation, two free a suction resulting in the production of heavier articles is compensated for by subsequent introduction of an excess of water, and vice versa.

Patent GB-642557-A (GB)
Title: Improved manufacture of carbon bisulphide
IPC: C01B31/26
Filed: 1948-02-16
Abstract: Carbon bisulphide is made by passing sulphur vapours, superheated to 600-800 DEG  C. by passage in countercurrent to and in direct contact with a moving bed of hot small particles of a refractory material, into contact with reactive carbon, e.g. charcoal, in an insulated <PICT:0642557/III/1> reaction zone maintained at a temperature not materially exceeding 850 DEG  C. solely by the heat of reaction.  As shown, molten sulphur from kettle 1 is vaporized at 4 and the vapours passed to a superheater 6 consisting of three refractory lined chambers 8, 9, 10.  Mullite pebbles, heated in chamber 8 by the combustion products of gas or oil burner 13, pass through chamber 9 wherein they heat the sulphur vapour and thence to chamber 10 from which they are returned to chamber 8 by an air lift, the air separated at 23 returning to a blower 25 via a dust separator 27. The heated vapours pass into an insulated reactor 28 to react with charcoal from a hopper 33.  Ash is removed periodically through outlet 30 while exit gases are passed to condenser 40, liquid carbon bisulphide passing to receiver 42.  Non-condensed gases pass to oil scrubber 44, hydrogen sulphide escaping through line 45.  The wash oil passes to reboiler 47 and stripper 48 whence the separated vaporized carbon bisulphide is returned to the condenser 40.  To start the reaction, the charcoal in chamber 29 is burned by air admitted through inlet 7 until a glowing zone is established, when the air is shut off and a flow of sulphur vapour started.  To prevent gas leakage from chamber 8 to chamber 9 or vice versa, the static pressure in the two chambers is equalized by adjustment of valve 15 in vent stack 14 and valve 38 in exit pipe 37 of the reactor.

Abstract: <PICT:0421429/III/1> A concentrated food product is obtained from citrus fruits by feeding the pulped fruits into a tank 20 containing an inert gas, from which it is then forced by a pump 22 to one or more spray nozzles 23 which distribute the pulp over the surface of a rotary drum 24, heated to about 175 DEG  F.  The particles of pulp are subjected to a uniform direct heat from the surface, and are separated from one another by exposed areas of the drum surface, whereby moisture content is reduced to below 24 per cent without injury to vitamins, esters and similar constituents of the juice. The dried material is finally removed from the drum by a water cooled knife 25, as a film 26 which may be folded into a laminated mass 27.

Abstract: 527,692. Shaping glass tubes. CORNING GLASS WORKS. Feb. 14, 1939, No. 4864. Convention date, March 19, 1938. [Class 56] A machine for making tubular blanks into bottomed containers comprises a number of chucks which seize and draw the blanks, and means for supplying air under pressure through the apertures of the chuck to assist in the formation of the bottoms of the tubes. The machine comprises two flanged sleeves 27, Fig. 2, which are slidable on a fixed sleeve 18 and can be moved to and from one another, by the rotation of a shaft 67, to adjust the mechanism to suit the length of the glass blanks. Gas burners 19 are secured to the middle part of the sleeve 18 between two tube-feeding discs 33. These discs are connected by bolts 34 with spider gears 28 which are rotatable on the sleeves 27 and are driven by a shaft 16. Chucks 36 are journalled on the spiders and are opened and closed, and moved to and from one another, by cams formed on drums 62 keyed to the sleeves 27. Tubes 53 pass through the stems of the chucks and their outer ends telescope into airsupply leads 87 carried by a disc 83 which rotates in contact with a fixed disc 81. This disc is formed with a channel through which air under pressure is admitted to the tubes 53 at appropriate times. Belts 92, driven by a shaft 17, pass over pulleys 42 on the chucks and rotate them when they are in the upper half of their circular path. In operation, glass tubes 40, Fig. 10, are fed on to an inclined shoot 41 and are picked up one at a time by the feeding discs 33. The ends of a tube are seized by chucks which rotate them as they are carried over the burners 19. As the central'portion of the tube softens, its ends are drawn apart by the chucks until the softened glass collapses and is separated by the flame leaving two bottomed tubes gripped by the chucks. Air is then blown through the tubes 53 into the glass tubes and shape the softened ends. Finally, the chucks open and discharge the bottomed tubes. The open ends of the containers so formed can be flanged by a machine, shown in Fig. 4, which comprises a single spider gear with chucks for holding the containers 104. The other spider head carries flaring-tools 103 instead of chucks, and these tools are moved up to, and flange, the ends of the containers which have been softened by the flames of a burner 108.
