Title: Improvements in or relating to calenders for laminating
IPC: B29C43/30
Filed: 1957-11-05
Abstract: 852,077. Laminating. DORNBUSCH, P., [trading as DORNBUSCH & CO.]. Nov. 5, 1957 [Nov. 14, 1956], No. 34417/57. Class 140. A calender assembly for laminating webs of thermoplastic material, or webs having a coating of thermoplastic material comprises a series of roller sets arranged one behind another, each set including a heating roller and a device for feeding a separate web and pressing it smoothly against the heated surface of the roller, the second and each subsequent set also including a counter roller, forming with the heating roller of the set, a nip through which the web or webs from the preceding set together with the web fed to the set are arranged to pass. As shown, webs 1-4, from alternative winding-off devices 5a-5d and 6a-6d, pass round guide rollers 7 to regulably heated rollers 8a-8d against which they are pressed by the belts 12 running on rollers 13a-13d, 14a-14d and 15a- 15d. At least the rollers 14 are driven, and the rollers 15 are adjustable to regulate the tension of the belt. Each of the heated rolls 8b, 8c and 8d co-operates with a counter roll 9. In another embodiment (Fig. 1, not shown) the belts 12 are replaced by smoothing rollers pressing the webs on to the rollers 8. When the webs differ in thickness, the thickest should preferably be supplied to the first roller as web 1. The calender rolls may be engraved to emboss, dull, glaze or calender the web surfaces.

Title: Novel lead fluorocarboxylate compositions and their use as polymerisation catalysts
IPC: C07F7/24
Filed: 1958-10-28
Abstract: Compositions for use as catalysts for the polymerization of ethylenically unsaturated monomers comprise one or more compounds of the formula X4-mPb(OCORf)m, where Rf is a perfluorocarbon or o -hydroperfluorocarbon radical, X is an hydrocarbon, acyloxy or halogen radical, and m is 1-4.  The catalysts are preferably used in the reaction medium in which they are prepared.  The polymerization is effected in a non-aqueous medium in the absence of moisture and oxygen, e.g. at room temperature up to 300 DEG C., and may be bulk polymerization where the monomer is liquid, or the polymerization of gaseous monomers.  Processes specified are the polymerization of fluorinated monomers such as tetrafluoroethylene, chlorotrifluoroethylene, hexafluoropropylene and perfluoroheptene-1 and the copolymerization of these with ethylenic monomers copolymerizable therewith.  Suitable reaction media for the polymerization are perfluorinated hydrocarbon solvents.  Examples prepare polytetrafluoroethylene, copolymers of tetrafluoroethylene with hexafluoropropylene, and a copolymer of tetrafluoroethylene with perfluoroheptene-1.  Specification 689,400 is referred to.ALSO:Lead fluorocarboxylates or mixtures thereof of the formula X4-mPb(OCORf)m, where Rf is a perfluorocarbon or o -hydroperfluorocarbon radical, X is a hydrocarbon, acyloxy or halogen radical, and m is 1-4, are prepared by acylating a compound PbX4 or a tetravalent lead oxide with the acid RfCOOH in the absence of moisture and oxygen.  Thus a tetravalent lead oxide such as red lead oxide is reacted with the fluoro-acid in the presence of a fluorocarbon acid anhydride; a lead tetra-acylate such as acetate, butyrate and benzoate is reacted with the fluoro-acid; a lead tetrahydrocarbon, such as tetraethyl, tetrabutyl, tetramethyl, dimethyl diethyl, and tetraphenyl, is reacted with excess of the fluorocarbon acid; or lead tetra-fluoride-, chloride, -bromide or -iodide is reacted with the fluorocarbon acid in the presence of a silver salt of a perfluorocarbon acid.  Mixtures of fluorocarbon acids may be used, and an anhydride or silver salt used which is not derived from the acid also employed, to obtain mixed products.  Specified fluorocarbon acids are trifluoroacetic, perfluorobutyric, hexafluorobutyric, perfluoroheptanoic, dodecafluoroheptanoic, hexadecafluorononanoic and octafluoropentanoic acids. Specification 689,400 is referred to.

Abstract: 898,878. Respiratory appliances. CHIRANA PRAHA, NARODNI PODNIK, and MICHALEK, J. Oct. 12, 1959 [Oct. 15, 1958], No. 34437/59. Class 81 (2). An ether evaporator has a device 6 adapted to drip ether on to a moderately sloped conical surface 5 defining the bottom of a shallow chamber 5a to spray drops of ether and cause the ether to flow down the surface 5 counter to a gas or mixture of gases passing at 9 into the chamber through a restricted aperture 10 and mixing with ether vapour before leaving the chamber at 16 through a pipe 11 and valve 12 to be supplied to the patient. As shown, Fig. 1, exhaled breath in a closed circuit system passes through a valve 1 and cock 2 to a carbon dioxideabsorber 3 and thence to a chamber 4 where its heat is passed to the underside of the surface 5. The purified gas passes through a pipe 7, the cock 2 and pipe 8, with the optional addition of oxygen or a gaseous anaesthetic from a pipe 13, to the chamber 5a and thence, enriched with ether vapour, to the patient. When operated in an open system, the cock 2 is adjusted to allow air entering the valve 1 from atmosphere to pass directly to the pipe 8. A bellows 14 enables the apparatus to be used in artificial respiration. The evaporator is preferably made of copper, aluminium or other sheet material of good thermal conductivity and a channel 15 around the upper part of the evaporator may be filled with warm water.
