The invention provides an apparatus for pre-processing sensor data that represent measurements of a physical parameter of a material under inspection. Sensors are employed to provide a multiplicity of data associated with a corresponding multiplicity of small areas of the material; and a multiplicity of reference data are also generated, each reference datum being associated with a particular sens...

This front jaw consists of a support body, on which two bent levers are mounted so as to be swivellable on vertical axles, and of a sole holder which is arranged so as to be adjustable on a vertical threaded bolt, the bottom end of which is mounted in the support body and the top end of which is mounted in a further bent lever, all three bent levers being under the influence of a single compressio...

This toe binding has a housing which is fixed to the ski and two angle levers which are rotatable about vertical axes and which bear with their longer lever arms against a ski boot to be inserted. The shorter lever arms are supported on a slide which is guided in the housing and stressed by a spring. Between the two angle levers, there is a vertical bolt which is mounted in the two prongs of the h...

A mixing valve includes a volume control valve (48), a pressure proportioning valve (82), and a thermostatic valve assembly (114, 130) within a single modular housing. The housing is rotatably mounted in a valve body and houses the proportioning valve and the thermostatic control valve. Rotation of the housing controls the total volumetric flow from the supply inlets (14, 16) of the valve plate (4...

The invention relates to a method and apparatus for controlling writing to a memory. The apparatus comprises control means (1-8) for the formation of a memory activation signal (C &cir& NOt E &cir& NOt ) in response to the applying of a predetermined key code to the control means, the control means comprising timer means (2) which are started by applying the key code and which prevent the formati...

Layered, fiber-reinforced composites toughened by the use of thermosetting matrix resins including rigid particles are improved in toughness when the particles are porous and formed of a polyamide. The method is particularly effective in improving the toughness of composites based on thermoset matrix resins, and particularly epoxy resins.

A downhole inspection tool (28) is attached to the lower end of a length of coiled tubing (24) having an electrical/fiberoptic cable (33) threaded through the centre. The coiled tubing carries a flow of optically clear and/or acoustically homogeneous fluid (52) from a supply of such fluid at the surface. The tool itself includes a cable head subassembly module (29) attached to the lower end of the...
