Title: Hose
IPC: B29C53/00
Filed: 1974-06-13
Abstract: 1470455 Hoses with fluid passages in walls TREG SpA 13 June 1974 [13 June 1973] 26351/74 Heading F2P An elastomeric hose comprises an open-pitch helical reinforcement coil 11 sandwiched between radially inner and outer reinforcing layers 4, 5 and 17, 18 with the space 13 thus defined forming a fluid passage extending helically along the length of the hose. The hose is made by successive addition of layers applied to the mandrel 1. Layers 2, 10, 15 are applied by helically winding a tape of elastomeric material; layers 3, 9, 14, 16, 19 are applied by helically winding tapes of square woven rubberized material; layers 4, 5, 17, 18 are reinforced layers of helically wound tapes of rubberized cord fabric. Reinforcing wire coils 6 and 7 are set in elastomeric material 8; an outer casing of elastomeric material 20 is also applied. The helical reinforcing coil 11 is made of successive windings of rubberized fabric tapes, reinforced to withstand radial compression stresses. The hose is cured by vulcanizing in an autoclave, during which process the fluid passage 13 is full of an incompressible material in a liquid, solid, or paste form, e.g. a mixture of paraffin and ethylene/vinyl acetate copolymer. This incompressible material may be applied before the application of layer 14 or may be injected into the passage 13 after construction of the hose. After curing of the hose construction the incompressible material is removed in a substantially liquid form. Buoyancy material may be added to produce a bouyant pipe.

Abstract: 297,089. Le Breton, L. Sept. 14, 1927, [Convention date]. Spray carburettors.-In a carburettor in which the admission of fuel to the constant level chamber g is controlled by a float p actuating a valve e through a lever r, the chamber g communicates with the mixing-chamber a through a calibrated orifice j, and with the atmosphere through an air inlet comprising a calibrated or valve-controlled orifice k. The fuel from the chamber g passes through a calibrated orifice h into a chamber i opening into the mixing-chamber through a conduit j. The valve l is provided with a conical part m acting to cut off the fuel, and with a tapered needle n coacting with a calibrated orifice o. In a modification, the lever r acts upon the float p through the intermediary of a disc which, should the fuel rise into contact therewith owing to the failure of the float, is adapted to float on the fuel and to operate the needle valve l.

Title: Improvements relating to steam separators
IPC: F16T1/06
Filed: 1948-10-11
Abstract: 667,567. Fluid-pressure servomotor-control systems. SUPERHEATER CO., Ltd., and RUDORFF, D. W. A. F. Nov. 11, 1949 [Oct. 11, 1948], No. 26467/48. Class 135 [Also in Group XIII] In a water discharge means for a steam separator, the discharge of the collected separated water is effected by a drain valve operable by a servomotor under the control of a thermo-responsive element or elements influenced by the temperature of the fluid taken from the working steam and continuously supplied to a throttling device wherein its pressure is reduced. As shown, a steam separator 1, Fig. 1, in a steam run 2, 3, is connected by a pipe 4 to a vessel 5 having baffles 6, Fig. 2 therein to prevent disturbance of the collected water. Within the vessels is an expansion chamber 21 open at its bottom end to atmosphere and communicating with the vessel 5 through a restricted orifice 28 and housing a thermo-responsive element comprising a copper tube 23 and a substantially non-expansible rod 25, e.g. quartz, connected by a lever 26 to a piston valve 18 supplied with pressure fluid through a pipe 20 and connected by a pipe 15 to the underside of a piston 33, Fig. 3. The piston is connected by a rod 31 to operate a drain valve 30. In operation, as long as the water level in the vessel 5 is below the orifice 28, steam will pass to the chamber 21 where it becomes superheated whereby its pressure is reduced and its temperature raised such that the element 23, 25 is inoperative and the valve 30 remains closed. On the water level in the vessel 5 reaching the orifice 28, the water passing into the chamber 21 reduces the temperature in the chamber 21 to that of boiling water at the corresponding pressure, hence the rod 25 moves outwards to lower the piston in the piston valve 18 to supply pressure fluid beneath the piston 33 and open the drain valve 30. Water then flows from the vessel 5 through a pipe 7, the drain valve 30, and when the apparatus is fitted to a locomotive, preferably passes through a force reducing device 10 containing, e.g. metal balls and a centrifugal separator 12, water passing through a pipe 13 on to the permanent way and steam passing to atmosphere through a pipe 14. In another embodiment the vessel 5 is dispensed with, the separator being connected direct to the drain' valve. Two expansion chambers are then fitted each with a throttling device and a thermoresponsive element, and connected in down pipes on either side of the separator 1, the down pipes leading to the drain valve casing. In this case the piston valve is responsive to the temperature difference between the two temperature responsive elements. If desired, the drain valve may be controlled by one expansion chamber and throttling device located on the upstream side of the separator. Specifications 598,160, [Group XIII], and 633,607, [Group II], are referred to.

Title: Improvements in or relating to the processes for the polymerization of 3,3-disubstituted oxetane
IPC: C08G65/18
Filed: 1957-08-22
Abstract: 3,3-Disubstituted oxetanes are polymerized in presence of an aluminium alkyl as catalyst.  Aluminium alkyls specified are Al(C2H5)3, Al[CH2CH(CH3)2]3, ClAl(C2H5)2, Al(isoBu)2H and also the tripropyl, trioctyl, tridodecyl aluminiums and the dimethyl, diethyl, aluminium bromides and chlorides ethylaluminium dichloride, dipropyl aluminium fluoride and diisobutylaluminium fluoride.  The polymerization may be effected at temperatures from - 50 DEG  to 300 DEG  C. in the presence of diluents, e.g. heptane, decane or dodecane and halogenated hydrocarbons, e.g. carbon tetrachloride, tetrachloroethane and trifluoro - 1,1,2 - tribromoethane.  Specified oxetanes are the 3,3-bis chloromethyl, fluoromethyl, bromomethyl, 3-chlormethyl-3-methyl, dimethyl and phenoxy methyl derivatives.  The properties of the end product may be modified by copolymerization of the above oxetanes with each other or with oxetane or substituted oxetanes. The polymerization may be effected in situ by passing the wire, metal, &c. surface to be coated through a bath of the monomer and catalyst mixture or by applying the mixture of monomer and catalyst to the surface to be coated and then heating the coated surface or laminate to the required temperature.  Polymers of increased molecular weight are obtained by first preconditioning the mixture by heating to low temperatures in presence of insufficient catalyst to effect polymerization at the temperature of preconditioning.  The examples all relate to the polymerization of 3,3-bis (chloromethyl oxetane.  In Example (3) the 3.3-bis chloromethyl oxetane is polymerized in presence of triethyl aluminium containing 0.4 per cent 2,21-methylene-bis (4-methyl-6-tertbutyl phenol) as stabilizer.
