A method of preparing a cylindrical-shaped innerliner (10) for storage. The method involves converting the innerliner (10) from a cylinder into a solid torodially-shaped donut (10A).

An optical system for measuring the reflectance of flat strips having potentially optically non-uniform surfaces. In one embodiment the systems includes an array of discrete light sources, wherein each light source is driven by its own individual current, such that the pattern reflected onto a photodector is substantially uniform in intensity.

A method of fabricating articles, such as prototype parts and prototype tooling for injection molding, is disclosed. The method begins with the fabrication of the article in a "green" state by the selective laser sintering, or another additive thermal process, applied to a composite powder, preferably a powder of metal particles coated with a thermoplastic polymer. Both the green article and also ...

The invention relates to a device for arming a radio alarm system, having a central alarm station (1), a plurality of detectors, these detectors being subdivided into two groups and the first group comprising detectors for securing the outside surface (outside skin, outside shell) and the second group comprising detectors for monitoring the interior space, and an additional closing device (2, 3) w...

The support bars (1) consist of at least two interlocking elements (4,5) by which they can be lengthened. Another flat element (17,18) is fixed to each of the interlocking elements.

Sprung cord pulls extend between two support bars adja...

An electrosurgical generator is disclosed that includes an exit spark control system. Exit sparking occurs when energy arcs to the patient as the active electrode is withdrawn from the patient. A basis for controlling the exit spark is to automatically change the frequency at which the final amplifier is driven whenever the conditions for an exit spark are detected. The change in frequency acts to...
