Rigid mould for moulding rubber tyres, constituted by a core 3 for defining the inner shape of the tyre, lateral portions 2 and a ring 1 of sectors. So as to be able to close such a mould, all the parts are designed to slide over each other during the final phase of their closing movement.

A method and apparatus is disclosed for electrically measuring the inside diameter of a metallic pipe such as oil or gas well casing. The transimpedance of two coaxial coils within the pipe is determined and then resolved into its inphase and quadrature components. The magnitudes of these two components are used to generate a corrected measurement output. A signal representative of the inside diam...

An apparatus for measuring earth formation parameters by transmitting and receiving electromagnetic signals by antennas (19, 21, 22) disposed in recesses in a tubular housing member (14) includes apparatus for reducing the coupling of electrical noise into the system resulting from conducting elements located adjacent the recesses and housing. The apparatus employs electrostatic, but not magnetic,...

A PVC wear layer is produced by applying a coatable preparation containing PVC, a crosslinking agent, a photosensitiser and, if appropriate, further conventional additives to a substrate and gelling it by means of heat. The gelled wear layer is then crosslinked by UV radiation. The wear layer obtained is heat resistant, as is especially clearly illustrated when cigarettes are stubbed out on coveri...

A method of forming a multilayer coated film comprising applying two or more nonaqueous layers to a continuously traveling flexible web, wherein at least one of the two or more coated layers comprises a coating composition containing an electron beam hardenable resin, and at least one of the two or more coated layers has a viscosity of about 100 cps or more, and irradiating the two or more coated ...
