Title: Production of foamed resins
IPC: B29D7/01
Filed: 1971-03-16
Abstract: 1338291 Making foamed sheets MONSANTO CHEMICALS Ltd 16 Feb 1972 [16 March 1971] 6957/71 Addition to 1264852 Heading B5A A foamed sheet is produced by extruding foamable thermoplastic resin through a die slit 1 into sliding contact with a first roller 5 having its axis parallel to the slit so that as the resin foams its expansion is restricted in a direction parallel to the slit by the frictional contact with the first roller, and passing the resulting foamed sheet 9 through the gap between the roller 5 and a second roller 7. The first roller 5 is stationary or driven in same direction as, but slower or faster than, the resin. The resin may also be in sliding contact with roller 7 or this roller may be an idler. The sheet is cooled by contact with part of the circumference of the rollers 5, 7 which are cooled internally with air or water, or externally by air jets 8. An air knife (not shown) may cool the resin sheet. The sheet is hauled off at a higher speed than it is extruded to reduce sideways expansion, using a roller nip or a co-operating tracks. A glass or matt surface may be imparted by a three roll calender or the sheet may be vacuum or pressure formed, and embossed or laminated to paper, fabric or film. The die is mounted on a screw extruder (not shown) which is heated electrically and cooled by water in coiled tubes fitted in grooves around the barrel. The die body, side plates and lips are separately heated by pressurized steam. Wall and ceiling panels, containers, and body panels and shells of cars, boats and furniture are formed from homo-polymers and co-polymers of olefins, vinyl and vinylidene monomers, and acrylates, including A.B.S. Nucleating agents are included in the resin and blowing agents comprising compressed gases, volatile liquids and decomposable solids are injected under pressure into the melt in the extruder.

Title: Preparation of ªÏ-laurinolactam
IPC: C07D201/04
Filed: 1966-02-17
Abstract: o -Laurolactam is prepared by reacting cyclododecanone with aqueous hydroxylamine until a mixed product of cyclododecanone and cyclododecanone oxime is obtained, separating said mixture and reacting it with HCl in the presence of a polar organic solvent to give a mixture of cyclododecanone and o -laurolactam, recovering the lactam, and recycling the cyclododecanone to the first reaction zone. Reaction with hydroxylamine is preferably at a pH of 4 to 7 and the product may contain 10-50% by weight of cyclododecanone; preferably 1/4 to 3/4 mole of hydroxylamine is used per mole of ketone.  The mixture of ketone and oxime may be separated from the reaction mixture by filtration or extraction.  Suitable polar solvents for the rearrangement to lactam include nitrocarbons, halocarbons and nitriles.  A catalyst may be used, e.g. phosgene, 1,3,5-trichloro-S-triazine, 2,4-dibromo-pyrimidine, a 2-chloroazacycloalkene or a 2,2-dichloroazaalkane.

Axial-flow type; combined-flow type; working- fluid supply; exhaust, treating ; vanes and nazzles ; regulating.-In a hydraulic impulse turbine, an annular nozzle J, Fig. 1, supplies a free circular jet having axial components of flow to rotor buckets 14, which are curved transversely of the stream lines of the jet. Water passes through an annular nozzle 12 adapted to be throttled by an annular plunger 13, on to the cup-shaped rotor buckets 14 which are semicircular in cross-section transverse to the flow and are curved backward with respect to the direction of rotation in the line of flow. The jet contacts with the hub along its inner surface, while in a modification in which the hub is conical there is an air space between the jet and the hub. The rotor hub may have a curved surface of revolution. In the construction shown in Fig. 6, the annular nozzle 34 is arranged to give a diagonally directed jet which impinges on to buckets 39. Stay-vanes 35 give a whirl to the jet, which can be throttled by a plunger 37. The discharge is received in a, cylindrical casing 44 which contains a wedge-shaped dividing wall 45 in a vertical plane containing the axis. The cup-shaped buckets described may have a discharge extending through an angle of nearly 180‹.

Patent GB-783061-A (GB)
Title: Process for the production of hydrocarbons
IPC: C07C1/06
Filed: 1956-03-08
Abstract: Hydrocarbons are produced by reacting carbon monoxide and hydrogen at elevated pressure and temperature in the presence of iron-containing catalysts which are suspended or fixedly arranged in a hydrocarbon oil which is constantly withdrawn at the upper end of the reaction chamber and introduced in circulation into the bottom end of the chamber, in which reaction, the hydrocarbon oil is freed from the major part of the carbon dioxide dissolved therein by expanding the oil to a pressure lower than the pressure used in the synthesis and then forcing it into the reaction chamber against the necessary pressure.  Preferably the pressure is reduced to about normal pressure to release the carbon dioxide, and also undesirable unsaturated hydrocarbons which are released at the same time. Specification 728,543 is referred to.

Title: Improvements relating to the separation of gaseous mixtures by washing
IPC: B01D47/06
Filed: 1936-03-16
Abstract: <PICT:0458393/III/1> In the separation of the components of a gaseous mixture by washing under pressure, a mixture for example of acetylene and methane at a pressure of 15 atm. is introduced at the lower part 1 of a wash tower 2 supplied with water at 3.  The saturated water containing the whole of the acetylene flows over baffles in a second tower 5, and escapes through a conduit 6 and expansion valve into a degasefying chamber 7.  The gas evolved is re-compressed and led to the lower part of the tower 5 and ascends in counter-current to the saturated water.  The cycle of flow through the degasefier 7 and compressor 8 may be repeated until the methane is removed from the wasting liquid, and a solution of acetylene only collects at the base of the degasefier.  The solution from the chamber 7 may be treated in another degasefier working at a still lower pressure.
