Patent GB-772114-A (GB)
Title: Improvements in or relating to processes for preparing hydrocarbon mixtures containing higher alkenes
IPC: C07C11/02
Filed: 1955-07-07
Abstract: Sulphuric acid alkyl ester salts are prepared by reacting 98 per cent sulphuric acid at 15 DEG  C. for 5 minutes, with a C8-C18 alkene fraction of a product obtained by cracking paraffinic hydrocarbon material (see Group III), and converting the sulphuric acid alkyl esters formed into sodium alkyl sulphates with caustic soda solutions.  Other alkali metal salts or the ammonium salt may also be prepared.ALSO:Hydrocarbon mixtures containing alkenes with at least 8 carbon atoms per molecule are prepared by vaporizing paraffinic hydrocarbon material in the presence of an inert diluent without cracking, removing unvaporized material entrained in the vapour by means of a cyclone separator, heating the vapour rapidly to cracking temperature, maintaining it at such a temperature for a short time of the order of a few seconds and condensing the cracked product as quickly as possible.  The inert diluent may be steam.  The cyclone separator may have a disc at the bottom forming an annular slot between its circumference and the vortex chamber wall, and a liquid coolant, such as liquid previously discharged from the separator, may be injected below the disc to cool the separated unvaporised material rapidly.  Superheated steam may be injected into the vapour following from the cyclone separator to the cracking zone to prevent condensation.  In examples paraffin wax is vaporized at 480 DEG C. in the presence of steam, passed through a cyclone separator, and cracked by heating for 2 seconds, in one case, at 570 DEG C., and in another case, at 558 DEG C. at a pressure of 1.2 atmospheres.  The products are rapidly cooled to 375 DEG C. and a C8-C18 alkene fraction separated by distillation.

Filed: 1972-04-27
Abstract: 1366960 Producing decorative affects on pile fabrics MONSANTO CO 27 April 1972 [28 April 1971] 19689/72 Headings DIB D1K and D1P Decorative effects are produced on pile fabrics comprising crimped synthetic pile fibre by applying to the surface of the fabric in pattern effect a contrasting agent (i.e. a compound having a swelling or solvating effect on the fibre causing a reduction in pile height), drying the agent on the fabric and subsequently subjecting the fabric to electropolishing, i.e. a treatment wherein the fabric is subjected to the rubbing and heating action of a heated, rotating, grooved, metal cylinder, to cause decrimping and to give a lustre finish to the fibres not treated with the contrasting agent. The fabrics include synthetic acrylic, modacrylic, nylon, polyolefin and polyester materials. The contrasting agents for application to acrylic and modacrylic fabrics include alkylene carbonates, acetone, dimethyl sulphone, tetramethylene sulphone, dimethyl formamide γ- butyralactone and nitromethane and may be diluted with an inert liquid, e.g. ethylene and propylene glycols or water, for application to nylon fabrics, 90% formic acid, benzyl alcohol, xylol, chloral hydrate and m-cresol, and for polyesters, m-cresol and trichlorobenzene. Electropolishing is carried out by passing the fabric on a belt or support member at 3-9 metres/minute to a polished heated rotating metal roll having longitudinal grooves which meet the fabric alternately at angles of about 15‹ and 165‹ with respect to the width of the fabric. The roll heated to 190‹C rotates at 700-1500 revs/minute, the fibre temperature being 121-205‹C. After crimp removal further electropolishing at 80‹ may take place to maintain the decrimped state.

Title: Apparatus for sterilising or pasteurising food-stuffs, especially milk
IPC: A47J39/00
Filed: 1952-08-06
Abstract: 714,221. Heat-treating food in containers. DEKKERS, P. M. C., and SIEBOLS, P. Aug. 6, 1952 [Aug. 14, 1951], No. 19860/52. Class 49 In apparatus for sterilizing food, especially milk, in stationary containers housed in a tank or similar reservoir by heating them by means of a mixture of air and steam and then cooling them in the same tank by means of damp air, there are one or more fans and associated valves so positioned that either the air in the tank may be made to flow in a closed circuit therein or atmospheric air may be made to flow therethrough. In the embodiment described with reference to Fig. 1, a thermally-insulated box 7 contains racks 8 holding crates of bottles of milk. In the top of the box is a propeller fan 1 over a central channel 9 in which is a steaminjector 2, a heat-exchanger 5 through which cooling fluid may be passed, and a heat-exchanger 6 through which steam may be passed. Water sprays 4 are provided above the racks 8. The top wall is provided with flap valves 3. For heating the bottles, the flap valves 3 are closed, steam is supplied to the heat-exchanger 6, the steam-injector 2 is opened, and the fan is made to rotate and so cause circulation of the air in the box. When the desired temperature, e.g. the required pasteurization or sterilizing temperature, or, in the case of yoghurt-inoculated milk, a temperature of 45‹C, has been reached, such temperature may be maintained by adjustment of steam supply to the injector 2 and through the heat-exchanger 6. For cooling, the steam injector 2 is closed, supply of steam to the heatexchanger 6 is stopped, and the valves 3 are gradually opened to begin propulsion of atmospheric air through the box. When the temperature has decreased sufficiently. the water sprays 4 are brought into action for further cooling. Still further cooling may be effected, and the low temperature be maintained, by closing the valves 3, closing the sprays 4, and supplying cooling fluid to the. heat-exchanger 5. Rotation of the fan is reversed periodically, if desired. There are also described and illustrated an embodiment in which a box has two communicating compartments of racks for holding crates of bottles, and a propeller fan, a steam injector, a set of water 'sprays and a heat-exchanger associated with each compartment, the heat-exchangers being connected, by means of a 3-way cock, for heating or cooling optionally, and an embodiment in which a propeller fan is mounted in an apertured compartment above two compartments of racks in a box and change in direction of air propelled through the box is effected by swinging a flap valve device in an apertured compartment above the fan compartment, without reversal of rotation of the fan.
