Date Jul. 14, 1988.A non-woven fibre product in which the fibre material consists, totally or in part, of fibres which are able to form bonds with natural or artificial fibres of the same or different type, and in which said fibres capable of forming bonds are ...

A Fourier Transform Ultra-Violet visible (FT/UV-Vis) instrument has no more than one moving part. It is adaptable inter alia to monitor fast reactions or to use in evanescent wave Attenuated Total Reflection Spectroscopy in the UV-Vis region. By using a Fourier transform generator the instrument has high sensitivity. Alternatively, a Hadamard transform generator may be used where the instrument ha...

A method of mounting photographic prints, for use in labelling, comprises longitudinally advancing adhesive transfer tape 2 carrying longitudinally spaced photographic prints 4 adhered thereto by the adhesive 3, and diverting the advancing tape sharply away from the main longitudinal path and then back to the main longitudinal path, each print and its underlying adhesive 3 from the tape on encount...

The multilayered composite wound dressing comprises of a semipermeable membrane, a permeable supporting and reinforcing layer, and a non-stick, self-sealing biodegradable tissue interface. The semipermeable membrane may be a synthetic collagen, an alginate or a biocompatible polymer and it controls the rate of water vapour transmission from the wound surface. The permeable supporting and reinforci...

The invention relates to a blood centrifugation cell, comprising an outer rotatable container (1) delimiting a portion of space in which a body is provided which is rigidly connected therewith and is formed by two revolution walls (2,3) connected at the ends, a stationary joint (10) being provided at the top of the container (1) and comprising two conduits (11,12) which are coaxial to the joint, t...

This invention comprehends a new and unique means for preventing the crowns (forward projections of the pleats) of a backflushable filter element from splitting due to the cyclic aciton that is experienced during cleaning and backflushing. In one embodiment, a plurality of spacers, preferably wedge shape, is positioned between the outwardly projecting pleats of the filter media thereby preventing ...

Apparatus and method for inspecting the finish of transparent containers, particularly glass containers, which include facility for directing diffused light energy laterally through the container finish as the container is rotated about its central axis. A camera includes a plurality of light sensitive elements disposed in a linear array angulated with respect to the container axis to view the ext...

A method of detecting defects present at the surface and/or internally in transparent materials, particularly of detecting included foreign bodies or bubbles in glass, is disclosed. The test material is scanned with an electromagnetic radiation of a single wavelength which is set to the penetration depth in the test material. The intensity reflected by the defects is picked up and analyzed. By thi...

The locations of defects in flat glass (1) are detected during conveyance through a detection station where the glass is scanned by a radiation beam (11). The beam sweeps transversely across the path of the glass through a distance in excess of the glass width so that the beam sweeps through both side edges. Beam deflection occurs when the beam encounters a side edge boundary of the glass (1) and ...

Hydrophilic thermoplastic polymers such as polyurethanes are stretched at a temperature above their glass transition point and then cooled to control axial swelling characteristics of the polymer in aqueous media; such polymers are especially useful for intravenous catheters.

A method is disclosed for absorbing bases, acids, alcohols and radioactive liquids using phenol resin foamed plastic particles. The size of the particles should lie between about 0.3 and 3 mm. The particles are initially closed-celled, but have been powdered or fine flaked. They may be treated with an acid for absorbing a base, or with a base for absorbing an acid. A preferred use is in the form o...

A heel piece for a safety ski binding is provided comprising a support member in the form of a slide member on which is pivotally mounted a sole holder having a pedal, a sole engaging portion and an interior cam surface configured to cooperate with a bearing member or cam follower which engages the cam surface. The cam follower is supported by a bearing lever having an axis of rotation near the up...

A vision navigation system for a mobile robot 21. The mobile robot has a plurality of light beacons 3, 5, 7 mounted on it to identify its location to fixed overhead television cameras 1 having a predefined viewing area. Navigation commands are generated by finding present robot location and transmitting new coordinates via the beacons which are used both for communicating with a master station and...

A reaction curable composition comprising, as reactive materials, a polyisocyanate component comprising a diisocyanate and a tri or higher functional polyisocyanate and having an average equivalent molecular weight of from 120 to 240, and a polyol component comprising a diol and a tri or higher functional polyol and having an average equivalent molecular weight of from 100 to 550.
