    摘要： a copolymer of ethylene with at least one other mono-.alpha.-olefine is prepared and is characterized as having a density in the range 918 to 940 Kg/m.sup.3, an apparent viscosity (A) at 200.degree. C and a shear rate of 100 sec.sup.1 of 0.5 .times. 10.sup.3 to 3.0 .times. 10.sup.3 Nsm.sup.2 and a viscosity at 200.degree. C and a stress of 10.sup.3 N/m.sup.2 of 2 Ae.sup.(1.6A 10 ) to 10,000 A.The copolymer from which the film is formed is preferably one in which the comonomer contains at least 5 carbon atoms; the comonomer may contain up to 12 carbon atoms. Hexene-1 is the preferred comonomer and can be present in the copolymer in an amount of 6.5 to 16.5%, by weight.The copolymers are readily processed and can be formed into films which combine good stiffness and good impact properties.The copolymers are conveniently prepared using supported transition metal benzyl compounds followed by a total work-up of the polymerization mixture. In particular, a process for forming the copolymers includes copolymerizing ethylene and the comonomer in the presence of a transition metal olefine polymerization catalyst and separating a polymeric product having an annealed characteristic set forth above.

    摘要： An insufflator for inflating body cavities, comprising a body to which a cannula and a needle are mounted, said needle being disposed in the cannula. The needle discharges gas from a regulator into the cavity gas from its distal end. A flow channel between the needle and cannula leads from the distal end of the cannula to the regulator. The regulator governs both the supply of gas to the cavity and the relief of excess pressure from the cavity.

    摘要： Hydrogen Sulphide is a toxic gas present in many environments. It is necessary for a detector to be highly sensitive and not to respond to other common gases. The sensor is made up of electrodes (5) coated with a thin layer (6) of material comprising the oxides of molybdenum and tungsten and in the presence of hydrogen sulphide gas, changes its resistance. The layer is formed in such a way that a bronze-like ordered lattice is formed, containing molybdenum, tungsten and oxygen ions.

    摘要： A transition metal composition has the composition M.sub.m,X.sub.p,TYn'Z where M is a metal of Groups Ib, IIa, IIIb, VIIa or VIII of the Periodic Table, X is an anion, T is a transition metal of Groups IVA--VIA of the Periodic Table, Y is an anion, Z is a melt-producing compound, m' is greater than zero and less than 100, n' is greater than zero and less than 8 (m'+1), and p' is m' x(valency of M)/(valency of X). The compositions of this type may be transformed into a liquid by heating and the hot liquid sprayed and the spray cooled. The sprayed material has a useful particle form and may be used as a component of a polymerization catalyst to polymerize an unsaturated monomer such as ethylene.

    摘要： The invention relates to combustible gas detectors of the kink in which a heatable wire filament exhibits a change in resistance due to a change in its temperature caused by the oxidation of a combustible gas passing over it. In order to avoid poisoning the heatable wire filament is embedded in a pellet consisting of a homogeneous mixture of an oxidation catalyst material and zeolite material the latter preferbly of type X, Y, L or mordenite of large pore size. Additionally layers of catalytically active material and/or inactive non-catalytic porous material may be provided around the outside of the pellet.
