APPARATUS FOR DETECTING THE PRESENCE AND THE QUALITY OF A FLAME BY DETECTING AND ANALYZING ELECTROMAGNETIC RADIATION OF DIFFERENT WAVELENGTHS Apparatus with an element for detecting and focusing the electromagnetic radiation emitted by the flame of a burner, and with an element formed by a light-conductive bundle of fiber optics for transmitting and separating the radiation of different wavelength...

Microemulsions based on perfluoropolyethers, comprising: an aqueous medium, a perfluoropolyether having a mean molecular weight of from 400 to 10 000 and perfluoroalkyl end groups; a fluorinated surfactant; and, optionally also a short-chain hydrogenated alcohol or a fluoroalkanol or a water-soluble salt, and microemulsion being permanently stable within a certain temperature range, in which the...

The invention provides an prosthesis as a vertebral replacement element, which consists of two helical strands, which may be screwed together with the formation of a tubular structure, inserted between vertebrae and then slightly unscrewed until the desired height is reached. The strands consist of carbon fiber reinforced composite material.

A flexible energy absorbing strap is provided to limit downward travel of a suspension system in reaction to rebound forces. The strap requires and uses connections already existing in the suspension system for attachment, and provides two flexible bands between the suspension beam and the vehicle frame.

An article including at least one segment which is capable of being elastically shirred along at least a portion of its length subsequent to manufacture of the article, preferably by mechanical manipulation of a predetermined portion of the elastically shirrable segment. The predetermined mechanically manipulatable portion of the elastically shirrable segment preferably comprises an elastomeric me...

A macroscopically expanded, three-dimensional fluid-handling polymeric web having first and second surfaces located in substantially parallel planes which are remote from one another. The web includes a multiplicity of fluid-handling capillary networks of macroscopic cross-section for rapidly transmitting fluids which are dynamically deposited on the first surface of said web to the second surface...
