Title: Improvements in and relating to package wrapping art
IPC: B65B51/02
Filed: 1924-04-24
Abstract: 241,959. Marks, E. C. R., (Pneumatic Scale Corporation, Ltd.). April 24, 1924. Packeting by wrapping-up.-Relates to a method of and machine for applying wrappers to packages, and in which a succession of adhesively-coated wrappers and a succession of packages are separately conveyed to an applying point, after which each packet and associated wrapper is moved along a closed path, at different points in which the wrapping is completed. According to the invention, adhesively-coated wrappers are fed by means of longitudinally-moving surfaces which are adapted to support the sheets lengthwise along a horizontal path and extending beyond the applying point, a light downward pressure being maintained on the wrappers, and the package being moved vertically through the path of the wrappers at the applying point so as to remove the wrapper from the surfaces. In the form of machine illustrated the package P and wrapper W are fed from opposite ends of the machine and in different horizontal planes towards each other at the applying station, at which the article and wrapper are inserted in pockets in an intermittently rotating spider. A succession of wrappers are fed down an inclined bed 22, Fig. 8, and are registered longitudinally by a reversible roll 28 and laterally by fingers 43 on an arm 41. They then pass between rollers 54, 55, Fig. 4, through a guide 56 and over a water roller 65, from which it is removed by a stripper 71 and directed on to an adhesive-applying roll 23. The roll takes adhesive from a supply roll 87 rotating in a tank 98 and feeds the wrappers to a stripper 100. Each wrapper. is guided beneath a plurality of spaced rollers 101, grooved to receive belts 121 and overlying sprocket feed chains 104. The two outer chains are at a higher level than the inner chains and cause the wrapper to sag at the centre so as to prevent any tendency to curl in the opposite direction. The wrappers are arrested by stops 128 pending the feeding of a package P into position beneath them. The packages P are raised by an elevator 148 to meet the overlying wrappers W and to carry them up into one of the pockets of a wrapping-spider.

Filed: 1964-02-26
Abstract: 997,509. Ventilating vehicles. S. SMITH & SONS (ENGLAND) Ltd. Feb. 26, 1964, No. 7976/64. Heading F4V. A motor vehicle heating and ventilating device comprises a housing 1 including partitions 2 and 3 which together form an air inlet compartment 4 containing a fan and communicating with a first passage 15 containing a radiator 16 and a second passage 19 which lead to a mixing chamber 26 from which air is supplied to the vehicle interior and to the windscreen, and flap valves 18 and 29 which control the entry of air to the first passage and the proportions of air passing from the first and second passages to the mixing chamber. The inlet compartment 4 communicates with a scuttle grille 11 via ports 9 and 10 and contains twin centrifugal rotors 6 and 7 driven by an electric motor 5 which impels air through openings 13 and 14 in a partition 12 in the inlet compartment to openings 17 and 20 to the first and second passages. Openings 27 and 28 lead from the first and second passages to the mixing chamber and openings 34 and 35 lead from the mixing chamber to compartments 23 and 24 which are connected by rubber ducts 36 to the windscreen. An opening 32 controlled by a flap valve 31 leads from the mixing chamber 26 to a chamber 30 connected to the vehicle interior by openings 33. The valves 18 and 29 are operated (Fig. 3) by a cam 38 through followers 43 and 48 and links 46 and 49. Springs 47 and 50 bias the followers into contact with the cam which is manually rotated by a link 39 attached to a plate 42 rotated by a cable (not shown). Fig. 3 shows an extreme position of the cam in which valve 18 closes opening 17 and valve 29 closes opening 28 so that no air can flow through the device. As the cam is rotated from this position, valve 29 closes opening 27 and valve 18 remains stationary so that cold air flows through the device. Further rotation of the cam uncovers the opening 17 and moves valve 29 back towards opening 28 which is closed in the other extreme position of the cam in which only hot air flows from the unit. The flap valve 31 is operated by a cable, link and cam, Fig. 4 (not shown), to vary the proportions of air passing from the mixing chamber to the vehicle interior and to the windscreen.

Title: Novel film-forming polymers of alpha, beta-olefinically unsaturated nitriles
IPC: C08F36/20
Filed: 1964-02-26
Abstract: Copolymers are made by copolymerizing an unsaturated nitrile and a polyalkenyl monomer until substantially all the monomers are converted to monomer, and then polymerizing additional unsaturated nitrile, which may be the same or different from that used in the first step, in the presence of the first-formed copolymer until a final conversion of 70-100% of monomers to polymer is obtained. Nitriles specified are acrylonitrile, methacrylonitrile, chloroacrylonitrile, crotononitrile and vinylidene cyanide. Polyalkenyl monomers specified are acrylic and methacrylic ester of polyhydric alcohols, allyl esters of unsaturated acids, allyl esters of polycarboxylic acids, non-conjugated diolefines, polyunsaturated ethers, polyunsaturated organometallic compounds of silicon, tin and germanium, polyunsaturated aromatic hydrocarbons, methylene-bis-acrylamide, and N-allyl and N-methallyl substituted acrylamides. The polymerization is preferably carried out in an aqueous medium having a pH of 2-8 in the presence of an emulsifier and a redox polymerization. The resulting copolymers may be formed into films from solution in polyacrylonitrile solvents, e.g. dimethylformamide.  The examples describe the preparation of copolymers in aqueous media in the presence of a persulphate/metabisulphite catalyst, t-dodecyl mercaptan, and either sodium lauryl sulphate or a phosphate ester as emulsifier, the monomers employed being: (1) acrylonitrile and tetramethylene diacrylate, (2) acrylonitrile, methacrylonitrile and tetramethylene diacrylate, (3) methacrylonitrile and tetramethylene diacrylate, and (6) acrylonitrile with each of ethylene, triethylene and tetraethylene dimethacrylates, divinyl benzene, diallyl maleate, allyl acrylate and divinyl butanediol.

Abstract: 768,692. Road-traffic signals on vehicles. ELLENBURGER & POENSGEN GES. March 19, 1954 [March 19, 1953], No. 8053/54. Class 118 (2). A flashing-light direction indicator system comprises a bimetallic interrupter 9 in series with the winding of a relay 13 the armature 15 of which operates contacts 16, 161 and 17, 171 to flash signalling lamps 23 or 24 on that side of the vehicle selected by the switch 4. A high resistance pilot lamp 27 is connected across the contacts 16<SP>1</SP>, 17<SP>1</SP> and flashes in series with the non-operative signal lamp. The flasher 9 is in the form of an envelope evacuated or filled with an inert gas and containing a bimetal strip 10 together with a heater coil. It is mounted in a socket 41 (Fig. 3), in a coverplate 40 for a casing 39 which also contains the relay 13. The armature 15 is mounted on the plate 40 by a flat spring 42 of magnetic material so as to be biased away from the core of the relay, with which it co-operates through a cut-away portion in the plate 40. The contacts 16, 17 are carried on springs 44 and 44<SP>1</SP>, not shown, to connect with fixed contacts 161, 17<SP>1</SP> carried on the cover-plate 40, unless the relay 13 is energized, whereupon the armature 15 depresses insulated pins 43 which pass through the plate 40 and separates the associated contacts. A cover 45 encloses the whole unit. In a modification (Fig. 2, not shown), instead of a pilot lamp 27 the windings of a differential relay are connected across the contacts 16<SP>1</SP>, 171 with their common mid-point connected to the vehicle battery via the ignition switch. The pilot lamp is connected via contacts closed when the differential relay is operated. When the ignition is switched on the differential relay does not operate unless a signal lamp has failed so as to cause unbalance of the currents in the two windings, in which case the pilot lamp lights. Unbalance is also caused when selector switch 4 is moved to one side and thus the pilot lamp flashes in rhythm with the signal lamps.

Filed: 1946-03-15
Abstract: Rubber-like polymers are made by polymerizing 2-vinylthiazoles of the formula <FORM:0609467/IV(a)/1> where Z is hydrogen or methyl.  The 4 and 5 carbon atoms may be substituted by methyl, ethyl, propyl, isopropyl, butyl, amyl, phenyl, p-chlorophenyl, b -naphthyl, ethoxy, chloro, benzo or tetrahydrobenzo groups.  Copolymers with butadiene-1,3, isoprene, piperylene and 1,2-, 1,3- or 2,3-dimethyl butadiene-1,3 and terpolymers including styrene, a -methylstyrene, o-, m- and p-chlorostyrenes, 2,5-dichlorostyrene, 2-vinylpyridine, 2-methyl-5-vinylpyridine, 5-ethyl-2-vinylpyridine, acrylonitrile, methacrylonitrile, methyl and butyl acrylates, methyl methacrylate and 2-vinylfuran may be similarly prepared. Polymerization may be effected in the presence of polyvinyl chloride, polyvinylidene chloride, polyvinyl acetate, urea- and melamine-aldehyde resins and unsaturated alkyds such as polyethylene maleate.  Examples describe polymerizing in emulsions containing sodium stearate, potassium persulphate and lauryl mercaptan, treating the latex with hydroquinone and a ketone-diarylamine antioxidant and coagulating with salt and dilute sulphuric acid.  The products are soluble in benzene, acetone, ethyl acetate, chloroform and solvent naphtha. They may also be dissolved in aqueous hydrochloric or sulphuric acids and precipitated by ammonium or sodium hydroxides.  The polymers may be mixed on the mill with polyvinyl chloride, polyvinylidene chloride and copolymers of vinyl chloride with vinyl acetate or vinylidene chloride.  The copolymers and terpolymers may be compounded with sulphur, carbon black, zinc oxide, coal tar softener and mercaptobenzothiazole and vulcanized.ALSO:2-Vinyl thiazoles may be prepared by condensing a 2-alkyl thiazole with formaldehyde to form the 2-(b -hydroxyethyl)-thiazole which is then dehydrated. Alternatively, a -benzoxythiopropionamide or a -benzoxy-a -methylthiopropionamide is condensed with an a -halogenated aldehyde or ketone and the product pyrolyzed, e.g. at 300-600 DEG  C. in the presence of activated alumina, to benzoic acid and the vinylthiazole. Or the esters may be hydrolysed with alkali to the corresponding carbinols which are then dehydrated by heating with activated alumina or potassium acid sulphate.
