A hollow fiber permeator is described which permits counter-current flow in the passage of feed/retentate and permeatesweep streams. The permeator comprises a bundle of hollow fibers compartmentalized using a series of concentric shells or a spiral wrap extending the entire length of the hollow fibers. The rings or spiral wrap are perforated along the top and bottom to permit even flow distributio...

A tarpaulin comprising a fabric coated with a plastics material, preferably PVC, polyamide or polyprene, is provided with a decoration of a reflecting material by anchoring a reflecting sheet to a piece of tarpaulin cloth, whose plastics coating is of the same type as or is compatible with that of the tarpaulin, by high frequency welding or heat application, and then applying the piece of tarpauli...

of the Invention Articles for food use are made by bonding ultra high molecular weight polyethylene surfaces. The surfaces are cleaned to remove grease and dirt. The surfaces are immobilized in spaced relation to each other with a rigid support abutting the surfaces. The surfaces are softened and a filler material surface softened with hot inert gas to make the outermost portion of each surface tr...

The appts. ties a thread round the outside of a bobbin (P1) after the thread has been wound on it. It includes a device for separating the end of the thread, and uses a suction tube (11b) which is moved adjacent to the outer layers and parallel to its axis, and then swung across its axis adjacent one end. Adjacent to the outer layers, near the other end is a sensor (12) which monitors the removal ...

The present invention pertains to an ultrasonic energy producing device for reducing the viscosity of oil and separating the water from hydrocarbon bonds.

An auricular implant includes a strip of flexible material having pores into which tissue can grow. The strip has the shape of a helix, the strip having an inner end adjacent to the center of the helix, an outer end at the periphery of the helix, an outer surface convex in a transverse direction, and an inner surface concave in a transverse direction. The material has the capability of attaching i...
