Title: Apparatus and process for preparing heat shrinkable plastics tubing
IPC: B29C33/40
Filed: 1975-03-12
Abstract: 1494257 Mould for forming heat-shrinkable tubing E I DU PONT DE NEMOURS & CO 12 March 1975 [14 March 1974 (2)] 10330/75 Heading B5A Plastics tubing is heated and radially expanded to form heat-shrinkable tubing, within a mould comprising a looped flexible sheet 10, the edges of the sheet beint held between clamp bars 12 which are movable to alter the diameter of the mould, and there being means for supplying a hot gas to the tubing interior while in the mould. The sheet edges 13 are clamped directly together (as in Fig. 1) or are spaced by a brass sheet supporting a shaped wedge, or by an aluminium spacer 18 (Fig. 7) supporting a flexible, resilient plate 19 that is tensioned and shaped by a nut 20 or by stainless steel hydraulic devices. The mould ends are each closed by an aluminium disc 11 (Fig. 1) sealed by a neoprene 0-ring and supporting a feed pipe 15; alternatively the stainless steel pipe 15 supports tacked neoprene washers that constitute the disc 11 and are forced against the mould by nuts on the pipe 15. The mould is cylindrical or tapered. Operation.-An extruded length of plastics tubing is mounted on a lathe, and a flexible sheet 10 looped about the tubing and clamped by aluminium bars 12 and C clamps to define a mould of larger diameter than the tubing, and having end plates 11. Steam is passed through the feed pipes 15 to heat the tubing interior, while condensate is removed by a dip rod, blowing, or tipping of the mould (sloped or vertical). The steam is pressurized to expand the tubing against the mould 10, whereafter pressurized air (cold) replaces the steam. When cool, the tubing is removed from the mould and its ends trimmed off. Materials.-The plastics tubing comprises a tetrafluoroethylene polymer, a polyolefin, an ionomer resin, a polyfluorinated polymer, polyamide, polyester, polyacrylic, or ABS. The flexible sheet 10 comprises one or more layers of a polyimide film, glass cloth coated with silicone rubber or fluorocarbon resin (e.g. PTFE), or nylon paper made of oriented aromatic polyamide fibrids. The cloth is woven, non woven or knitted. Heating and blowing are carried out by superheated steam, air, or carbon tetrachloride. Uses of tubing: packaging foods or covering rollers.

Patent GB-798947-A (GB)
Title: Process for the manufacture of carbon disulphide
Inventor: FOLKINS HILLIS OTTY
IPC: C01B31/26
Filed: 1955-04-12
Abstract: Carbon disulphide is produced by interacting, in the gaseous state and in the presence of a catalyst, sulphur and an olefinic hydrocarbon, and/or a saturated hydrocarbon containing at least 3 carbon atoms in the molecule, or a mixture of one or more of such hydrocarbons and methane and/or ethane, the catalyst being periodically regenerated.  The catalyst may be activated alumina, silica gel, fuller's earth, bauxite, or silica-alumina gel containing 2-10 per cent of silica.  Catalyst promoters, e.g. oxides or sulphides of iron, chromium, manganese, molybdenum and vanadium, may be present.  The mixture of reactants may be heated to 850-1300 DEG F., preferably 1100-1175 DEG  F., prior to reaction. The pressure may be subatmospheric or superatmospheric, e.g. up to 500 p.s.i., preferably 100 p.s.i.  An excess, e.g. 10-30 per cent, of sulphur is preferably employed.  Inert gases, e.g. nitrogen or flue gas, may be included in the reaction mixture. The reaction may be operated isothermally or adiabatically. Reactivation may be effected by purging at atmospheric or superatmospheric pressure with oxygen-containing gas, e.g. air at 800-1200 DEG  F., liquid or vaporous sulphur at 500-1200 DEG  F., preferably 1100 DEG  F., or steam at 1000-1200 DEG  F., in particular at or above reaction temperature with sulphur mixed with methane, or methane and ethane, in considerable stoichiometric deficiency. One or more static beds of catalyst may be on stream while a similar number are being regenerated.  Using a moving or fluidized bed, catalyst may be continuously removed, regenerated and returned to the process.  Using sulphur vapour a temperature of 500-1200 DEG  F., preferably 1100 DEG F., may be employed.  Passage of sulphur vapour is continued until liquid sulphur withdrawn from the reactor is free from discoloration. A single reactor with continuous production of carbon disulphide may be employed if during regeneration methane or ethane is admixed with the sulphur and a temperature of 1000-1200 DEG  F. is employed.  The product gases are cooled, e.g. by passing through a waste heat boiler, an air-cooled multi-finned radiator, or conventional water cooler, and scrubbed with liquid sulphur in a tower provided with bubble plates, or Rasching rings.  The sulphur is recycled to the process.  The point at which regeneration is required is determined by inspection of the recycled sulphur.  The remaining sulphur is removed by scrubbing in a similar tower with lubricating or light gas oil.  The carbon disulphide may be recovered by absorption in petroleum naphtha of b.p. 250-400 DEG  F., benzene, or O-dichlorobenzene, followed by stripping and fractionation.  Scrubber oil containing sulphur is cooled to 100 DEG  F. or lower, sulphur crystallized therefrom, and removed by sedimentation, filtration or centrifugation.  Specification 644,030 is referred to.

Title: Improvements in or relating to edible emulsions for use as salad dressings
IPC: A23L27/60
Filed: 1938-04-08
Abstract: 510,821. Salad dressings. CONTINENTAL SOYA CO., Ltd. April 8, 1938, Nos. 10870 and 10871. Convention dates, Sept. 9, 1937, and Dec. 24, 1937. [Class 49] A salad dressing consists of an oil-in-water emulsion containing at least 10 per cent. by weight of an edible oil or fat emulsified with vinegar or acetic acid, water and soya bean protein obtained from soya beans by removal of the major portion of the oil. The soya bean protein which acts in association with the acetic acid as a stabilizing or emulsifying agent may be obtained by removing the oil from the beans by hydraulic pressing, crushing between rollers or, preferably, solvent extraction, and then grinding. The soya bean material is preferably not heated to a temperature higher than 160‹F. at any stage in its processing. The protein may be separated by heating this product with water and common salt to about 180 ‹F. with agitation for an hour, separating the fibrous material by filtration, adding dilute acid to the filtrate, filtering off the precipitate obtained and washing it with dilute acid solution and pressing the residue on the filter. The salad dressing may contain 5-20 preferably 10 per cent. by weight of soya bean protein, 10-80 preferably 25 per cent. of water, 10-75 preferably 65 per cent. of oil and 0.4-2 preferably 0.6 per cent. of acid calculated as pure acetic acid. The product can be thinned by adding water or dilute organic acid solutions without breaking the emulsion. In examples, (1) 10 pounds of water, 12 pounds of separated protein and 12 pounds of vinegar are mixed for 3-5 minutes whilst salt, sugar and spices are added. Then 65 pounds of an edible oil, e.g., corn oil, is run into the batch continously but slower as the emulsion thickens. (2) 20 pounds of water, 10 pounds of de-oiled soya bean ground to a powder of 200 mesh or finer and 12¢ pounds of vinegar are mixed for 3-5 minutes whilst adding sugar, salt and spices totalling 3 pounds. The salt and sugar may be dissolved in the vinegar prior to mixing. 30 pounds of an edible oil, e.g., refined soya bean oil, are run in while the mixer is operating and the product is passed through a high-speed colloid mill, homogenizer or similar apparatus.
