Date Mar. 1, 1984.A method and a device for operating and focusing a tomographic x-ray unit using an electron beam and embodying at least one electron gun (1), an anode (2) at which the gun is aimed as well as the x-ray detectors (5) needed to produce a tomogra...

Polyurethane foam products comprising a foam filled with a foam and a large amount of combustion retardant materials are described. The foams are prepared by foaming a polyurethane foam-forming diisocyanate and polyol around pre- formed polyurethane foam chips having incorporated therein solid combustion retardant materials. The polyurethane foam-filled foams are suitable for furniture upholstery ...

Foams having aspartase-producing microorganisms bound to the foam are made from polyurethane prepolymers which are capped with polyisocyanates, including diisocyanates, derived from methylene-bis (phenyl isocyanate) which is commonly known as MDI. These MDI based foams are hydrolysis resistant as compared to the previously used TDI based foams. The foams can be used to produce L-aspartic acid unde...

A melt-molded film of a wholly aromatic polyester, said film having in its plane two perpendicularly crossing directions in each of which the Young's modulus and strength of the film at 25 DEG C. are at least about 200 kg/mm2 and at least about 5 kg/mm2 respectively, the product of the Young's moduli of the film in the two directions being at least 8x104 (kg/mm2)2, and said wholly aromatic polyes...

Mixtures which are used for the production of polyurethane foam and which contain amines having primary or secondary aliphatic hydroxyl groups, and also customary quantities of trichlorotrifluoroethane and/or trichlorofluoromethane as a blowing agent, can be stabilized against the premature reaction of the components by adding 0.05 to 5% by weight of 2,4-diphenyl-4-methylpentene in which the ratio...

Thermoplastic elastomeric films comprise from about 40% to about 80% of an elastomeric block copolymer and from about 20% to about 60% of an ethylene-vinyl acetate copolymer. The block copolymer has at least two monoalkenyl arene polymer end blocks and at least one elastomeric conjugated diene midblock. The monoalkenyl arene polymer blocks comprise from about 8% to about 55% by weight of the block...

A hydraulic actuator for a vehicle brake incorporates an automatic adjuster which includes a strut of variable length formed by members which are threadedly interengaged by way of non-reversible screw thread connection. The member is an adjuster shaft which forms a reversible screw thread connection with a drive ring arranged to control rotation of the adjuster shaft during brake application and r...

A non-smouldering foam material is derived from a latex of a butadiene rubber with optionally natural rubber latex by treatment with up to 15 parts by weight per hundred of rubber with either a reclaiming agent or guanidine or a derivative of guanidine. The reclaiming agent, which hastens depolymerisation of rubber, may be a thiol, a disulphide or an aliphatic primary amine. Preferably the guanidi...

A process for forming an olefinic resin film on a metal substrate, which comprises [A] forming a multilayer coated film consisting of an olefinic resin film as a surface layer portion and a cured epoxy resin film as an under layer portion on a metallic substrate by a single coating operation using a multilayer film-forming coating composition comprising as main resinous components (a) a solid powd...
