Title: Improvements in or relating to the production of composite articles, structures and the like containing polythene
IPC: C09D185/02
Filed: 1949-08-23
Abstract: Polythene or a composition consisting mainly of polythene is (a) coated with or (b) joined to a material other than polythene, e.g. glass, paper, metal, rubber, wood or textile, by a resinous polymeric aromatic phosphoric ester having a recurrent unit <FORM:0683209/IV (a)/1> p  where R1 is an aryl group which may have one or more aromatic nucleus and may contain halogen or alkyl substituent groups, and -O-R11-O- is the radical or an aromatic dihydroxy compound whose nuclear hydroxy groups are attached to non-adjacent carbon atoms. Such polyesters are described in Specifications 644,468 and 679,834. The polyester may be employed in molten condition or dissolved in a volatile solvent, e.g. ethylene dichloride or mixtures of benzene or toluene with alcohol.  When employed as a coating composition further coatings based, e.g., on nitrocellulose, drying oils, or natural or synthetic resins may be applied to the polyester.  Metal coatings may be applied by spraying.  A rigid body coated with the polyester may be sprayed with molten polythene or may have a preheated polythene sheet applied thereto with pressure.  The polyester may contain other ingredients, e.g. polyvinyl acetate, nitrocellulose, pigments or dyestuffs.  In examples: (1) a polyester derived from 2 : 4-dichlorophenoxy phosphoryl dichloride and hydroquinone is dissolved in ethylene dichloride, pigmented with Monolite Fast Scarlet and brushed on a polythene tube; (2) a polyester derived from o-phenyl phenoxy phosphoryl dichloride and hydroquinone is dissolved in a mixture of toluene and alcohol and brushed on polythene; (3) a polyester derived from 2 : 4-dichloro phenoxy phosphoryl dichloride and 4 : 41-dihydroxydiphenyl is dissolved in a mixture of benzene and alcohol and painted on a vessel made from an alloy of lead and antimony.  The coated vessel is heated and molten polythene is sprayed on the coated surface.  The polyester of example (1) is spread on a steel sheet, covered with a polythene sheet and the resulting sandwich subject to heat and pressure.

Title: Process for the preparation of vinyl boron compounds
Inventor: RAMSDEN HUGH EDWIN
IPC: C07F9/50
Filed: 1958-07-09
Abstract: Vinylic boron compounds, which may contain attached to boron one or more halide, alkoxide, aryloxide or hydrocarbon radicals (for preparation see Group IV(b)), may be copolymerized with styrene, vinyl acetate, vinyl chloride, butadiene, acrylates, esters, acrylics and other vinylated metals or metalloids such as vinyltins, vinylsilanes, vinylarsenic and vinylantimony. Specifications 792,537 and 826,621 also are referred to.ALSO:Vinylic boron compounds are made by reacting a vinylic magnesium chloride complex of formula ViMgCl.nQ, wherein Vi is a vinylic radical R1.C(R11) = C(R111)-, R1, R11 and R111 being either hydrogen or a substituted or unsubstituted hydrocarbon radical containing no group reactive under the conditions of the reaction, including cycloalkenyl-1 radicals, Q is a substituted or unsubstituted cyclic ether having 5 or 6 atoms in the ring, which may have a nitrogen atom in the 4 position, contains not more than one double bond and at least one free carbon atom adjacent the oxygen atom, and n is an indeterminate small number of the order of 1 to 3 with a boron halide, alkoxide or aryloxide or with an organo-substituted boron halide, alkoxide or aryloxide, the organosubstituent of which contains no group reactive with magnesium or said complex.  The vinylic boron compounds so obtained, provided they contain at least one halogen, alkoxy or aryloxy radical attached to the boron atom, may be further reacted with an organomagnesium chloride complex of formula RMgCl.nQ wherein R is a substituted or unsubstituted hydrocarbon radical or activehydrogen free heterocyclic radical containing no group reactive under the conditions of the reaction.  The reaction may be effected in an inert solvent at temperatures from -40 DEG C. to the boiling point of the solvent. The reaction is preferably effected in an inert atmosphere, e.g. nitrogen.  As an alternative, Q in the vinylic complex may be replaced by an ethylene polyether by the method described in Specification 826,621, and the complex formed used in the above reaction.  The vinylic boron compounds may be polymerized with unsaturated compounds and other vinylated metals or metalloids. Specification 792,537 also is referred to.

Abstract: 695,642. Feeding webs. MASCHINENFABRIK WINKLER, FALLERT & CO., AKT.-GES. Sept. 7, 1950 [Oct. 26, 1949], No. 22102/50. Class 100(i) [Also in Group XXXIV] An automatic brake regulating mechanism for the paper rolls of the web supply apparatus for rotary printing machines is of the kind in which paper rolls are carried on a rotatable spider and in which each of the rolls is braked by a brake acting on a cone supporting the roll. Paper rolls 1-3 are carried by arms 7 rotatable by an axle 4 driven by an electric motor 9b to bring the individual rolls into running position. The web 10 being unwound passes around a feeler roller 11 carried by levers 12 secured to a shaft 13 also carrying a lever 14 having an adjustable weight 14a thereon. The lever 14 is connected to a lever 15 pivotally connected to a lever 17. The lever 17, Fig. 1, carries gears 18 and 19, which mesh with and roll upon gears 20 and 21, the lever 17 and gears 20, 21 being rotatably mounted about a shaft 20a journaled in a base 24. Gears 22 and 23 are mounted on a pin 22a secured to the base 24, the gears 22 and 23 meshing with gears 20 and 25. The axle 4 carries shafts 26 having levers 27 connected through links 28 with pins 28a on the gear 21. The shafts 26 have keyways and carry levers 29 having keys, the opposite ends of levers 29 being connected to rods 30 and actuating members 31 for internal shoe-drum brakes 32, 33, 34 such that displacement of the roller 11 causes a corresponding braking of the roll being unwound. Assuming the arms 7 to be stationary, the gear 20 does not rotate when the gears 18 and 19 move downward, the gear 18 thus rolling on the gear 20 and so rotating the shafts 26 through the gear 21 and levers 27 and links 28 to actuate the brakes 32, 33, 34. If the arms 7 are rotated with the axle, the gear 25 drives the gear 21 through gears 22, 23, 20, 18, and 19, the gears 21 and 25 moving synchronously providing the roller 11 remains stationary. In order to brake only the roll being unwound, the axis of rotation of the lever 17 and the axis of the shaft 20a, are arranged eccentrically to the axle 4.

Title: Improvements relating to the control of the flow of fluids, particularly of the feedwater supply to steam boilers
IPC: F22D5/18
Filed: 1936-08-15
Abstract: 474,538. Fluid - actuated valves. COPES REGULATORS, Ltd. (Northern Equipment Co.) Aug. 15, 1936, No. 22545. [Class 135] A valve regulating the flow of a fluid such as the feedwater supply to a boiler and actuated by the fluid pressure is controlled by varying the fluid pressure acting on the valve in accordance with the movement of the valve. A boiler feed valve 25, Fig. 2, is actuated by a piston or the like 22 acted upon by the pressure of the feedwater taken from the feed line 19, through a pipe 33, and the pressure on the piston is varied by the valve movement which is communicated to an auxiliary valve 30 controlling the escape of water from the pipe 33 through a pipe 23. The water pressure on the piston tends to close the valve against the opposing pressure of a spring or weight 26 and of the boiler steam admitted below the piston through a pipe 29. The movement of the auxiliary valve is adjustable, and its ports 72, 73, Fig. 6, may be elongated and of gradually increasing width. The water is supplied to a boiler through an economizer, fromwhich it passes through a valve operated by a regulator responsive to changes in the boiler water level. Specification 474,360, [Group XIII], is referred to.
