Title: Improvements relating to the prevention of interalloying in multiple-layer galvanizing baths
IPC: C23C2/06
Filed: 1936-08-11
Abstract: Interalloying of the lead and zinc in galvanizing baths using the lead-zinc process is reduced by using for the upper layer crude zinc which has been deoxidized, for example by the process described in Specification 450,690, and for the lower layer lead containing manganese, e.g. to saturation point.  Manganese may be added to the lead in the form of a commercial tinmanganese alloy, the tin being then driven off by alternately allowing the mixture to cool slowly and reheating it as often as necessary.  Further manganese may then be incorporated in the lead by the addition of manganese dioxide and a reducing agent.  The manganese need not be present throughout the whole of the lead bath, but may be only in the upper layers, in which case a layer of lead manganese alloy separates the pure lead from the zinc.  The Specification as open to inspection under Sect. 91 refers also to chromium as an element which can be added to the lead to prevent interalloying between the lead and zinc.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to synthetic rubber paste latices
IPC: C08F36/04
Filed: 1952-09-05
Abstract: Synthetic rubber paste latex is prepared by polymerizing in aqueous emulsion a monomeric material comprising a conjugated diene, in the presence of an emulsifying agent, a modifier and a catalyst, while maintaining in the emul-from 15 to 40 parts of water per hundred of the monomeric material.  Specified dienes are butadiene, isoprene, piparylene, 2,3-dimethyl-butadiene, 3-furyl-butadiene, 3-methoxybutadiene, chloroprene, bromoprene and methylchloroprene which may be polymerized alone or with sytrene, p-chlorostyrene, p-methoxystyrene, alphamethylstyrene, vinylnaphthalene, acrylic acid, methacrylic acid, methyl acrylate, ethyl acrylate, ethyl acrylate, methyl alpha-chloro-acrylate, methyl, ethyl, or butyl methacrylate, methyl ethacrylate, acrylonitrile, methacrylonitrile, methacrylamide, methyl isopropenyl ketone, methyl vinyl ketone or ether, vinyl acetate or chloride, vinylidene chloride, and vinyl furane, carbazole or acetylene.  Specified emulsifying agents are potassium laurate or oleate, salts of alkyl aromatic sulphonic acids and salts of alkyl sulphates and they are usually used in an amount between 0.3 and 5 parts per hundred of monomeric material.  Specified modifiers are mercaptans and specified catalysts are cumene hydroperoxide and tert-butylisopropylbenzene hydroperoxide.  Highly active systems such as iron pyrophosphate-hydroperoxide and diazoether are preferably employed for the polymerization which preferably takes place at between -40 DEG  C. and 70 DEG  C. with a pH between 9 and 12. Particularly when the temperature is below freezing water-soluble components may be included, e.g. ethylene glycol, glycerine, erythritol and methyl alcohol.  The polymerization is usually carried out while the materials are being agitated, the agitation preferably being discontinued before completion of the polymerization.  The latex may be compounded with the usual vulcanization materials and cured.ALSO:An apparatus for use in aqueous emulsion polymerization to produce a synthetic rubber latex comprises a reactor 10 formed by cylindrical wall 9 and surrounded by water jacket 11.  The reactor contains shaft 12 axially disposed therein and rigidly attached at its lower end to upwardly extending vanes 13 above and adjacent plate 14, disposed immediately above closure member 16 of chamber 10 and nearly closing chamber 10.  This chamber is closed pressure tight by top member 17.  Vanes 13 are so arranged as to knead the reaction mixture when shaft 12 is rotated.  Splined shaft 21 passes through closure member 16 and packed section 22 and engages shaft 12 so as to rotate it, in a continuous or alternative direction, being itself rotated by driving means 23.  When polymerization is complete top closure member 17 is opened on hinges 18 and the latex removed by engaging shaft 12 to ring 28, so raising the shaft and forcing out the paste-like product. <PICT:0727601/III/1> <PICT:0727601/III/2>

Title: Improvements in or relating to tools adapted for use in blind riveting
IPC: B21J15/06
Filed: 1960-06-27
Abstract: 952,202. Blind riveting tools. GEORGE TUCKER EYELET CO. Ltd. June 27, 1960 [June 29, 1959], No. 22363/60. Heading B3U. A setting tool for blind rivet assemblies set by a break-off mandrel comprises a tubular body 2 which has a rivet-head engaging abutment 4 at one end, a flexible diaphragm 15, means 22 connecting the diaphragm to the pulling device of the tool and valve means whereby air pressure can be admitted to one side of the diaphragm to cause relative movement between the body and the pulling means. The diaphragm 15 is clamped between the two parts 10 and 12 of a non-metallic housing and is connected by a rod 22 to a sleeve member 32 which houses a plurality of jaws 34 arranged to grip and pull a break-off mandrel M. The diaphragm 15 and the rod 22 are biased toward the front of the body by springs 38 and 36. Air under pressure is admitted to the chamber 20 by a trigger-controlled valve 42 and is exhausted from the chamber 20, by the action of the springs 36, 38, through a port 54. Some of the air being exhausted passes through a clearance 50, around the rod 22, through ports 51 in the sleeve 32 and ejects the broken-off part M of the mandrel. The part 12 of the housing has an opening 56 to permit air on the unpressurized side of the housing to escape. The opening is of such a size that the rapid escape of a large volume of air is prevented thus preventing sudden backward movement of the diaphragm when a mandrel breaks. The restrictive effect can be enhanced by fitting a flexible baffle 58, normally spaced from the opening, but forced over it by a sudden rush of air so as to momentarily close the opening. Specifications 348,818, 405,993, 567,586, 578,104, 587,938, and 793,365 are referred to.

Title: An improved apparatus for purifying oils
IPC: C11B3/06
Filed: 1939-08-04
Abstract: 534,338. Purifying oils and fats. COLBETH, I. M. Aug. 4, 1939, No. 22630. [Class 91] Apparatus for purifying crude oils and fats by countercurrent treatment with alkali comprises an upper chamber 17 with a restricted throat at its base with a tangential washing water inlet 16, and a lower chamber 1 with a conical extension 6 and inlets 3 and 4 for the oil or fat and alkali respectively. The crude oil or fat is distributed over the whole of the chamber 1 in its upwardflow by the perforated ring 7 which also, in conjunction with a packing 13 of nails, divides it up into small droplets. The oil or fat therefore comes into intimate contact with the alkali, preferably caustic soda, which enters at the inlet 4. The soap formed by the alkali and fatty acids in the oil or fat is washed out by the downflowing water from the container 17 and carried out, along with the excess of alkali, through the pipe 5. The oil, from which the fatty acids have been washed passes up through the neck 15 into the upper chamber 17. The washing water, entering at 16, causes the droplets of oil or fat to coalesce and the water and oil or fat separates out into two layers in the chamber 17. The purified oil is drawn off by the pipe 19, which passes up to the top of the chamber 17, and the water is drawn off by the pipe 18.

In a welding circuit arrangement direct current is obtained through a three-phase rectifier arrangement R1, R2 whose input circuits include saturable reactors A1, A2, A3, which have one or more control windings B1 whose current is controlled by a heavy-duty main variable resistor R5 and a light duty remote variable resistor R4, this resistor being portable by the welder and capable of giving fine control of the welding current. As shown the current through B1 is obtained from a rectifier R3 which includes A.C. windings A4, A5 of a saturable reactor in its supply circuit. The control winding C of this reactor and a remote resistor R4 are in series across the rectifier so that R4 controls the current to the rectifier and hence the current in B1, thus controlling the output current. In an alternative arrangement (Fig. 2, not shown) two currents flow in the control winding B1, one being obtained from a first rectifier and controlled by R5, the other being obtained from a second rectifier having a saturable reactor in its supply circuit. The control winding for this reactor and the series-connected remote variable resistor are supplied from the first rectifier.

Title: Improved method and apparatus for polymerization of olefins
IPC: C08F10/00
Filed: 1957-07-22
Abstract: In processes for the low pressure polymerization of olefins the molecular weight of the polymer is maintained uniform by measuring, at constant concentration, the viscosity or osmotic pressure of the effluent polymer solution and then con <PICT:0858549/IV(a)/1> <PICT:0858549/IV(a)/2> trolling the temperature of the reaction zone responsive and p  directly proportional to changes from a predetermined value of said viscosity or osmotic pressure.  Monomers specified are ethylene, propylene, butylene and their mixtures with butadiene or isoprene.  The catalyst may be chromium oxide, or TiCl4 + an organo aluminium compound or a mixture of a halide of a Group IV metal with a free metal.  In Fig. 1. the polymerization is effected in the reactor 8 which is provided with a cooling coil 10.  Part of the polymer solution is passed via 12 and 17 through a differential refractometer 16 which produces an electrical impulse by comparison with a standard solution and transmitts the signal to controller 20 which in turn controls the pump 24 whereby the catalyst feed rate to the reactor is adjusted and a constant polymer concentration thus attained.  The remainder of the reactor effluent is passed through a viscomiter 34 which transmitts a signal to recorder controller 38 and to temperature recorder controller 40, which in turn operates the valve 42 thus effecting control of the flow of cooling fluid to coil 10 whereby the temperature in the reactor 8 is controlled.  In Fig. 2 the refracto-meter 16 produces a signal which is converted to a pneumatic signal in transmitter 43, said signal being passed to recorder controller 41 which controls valve 39.  Solvent via 4 and 37 is thus added, under control, via valve 39 whereby a constant concentration of polymer solution entering refractometer 16 is attained.  The remainder of Fig. 2 corresponds to Fig. 1.  The processes may be operated with instruments for measuring dielectric values in place of the refractometers.  An example illustrates the changes in refractive index and viscosity which occurs during a polymerization of ethylene in cyclohexane using chromium oxide as catalyst.
