A method of making a metal composite part by compacting a metal powder composition in a die whose wall surfaces have been electrostatically coated with a lubricant, thereby eliminating or reducing a lubricant in the metal powder composition, resulting in a metal composite having greater density and strength. The method further includes providing an electrostatic charge to the metal powder composition. A powder metallurgy apparatus is also provided.

Powder metallurgy apparatus and process using electrostatic die wall

A mixture of particles of plastic materials having different work functions is fed through a rotating tube. The tube rotates about an axis which is inclined slightly to the horizontal. The tube is of plastic or metallic material, preferably having a rib for stirring the mixture. As the particles pass progressively down the length of the tube, the triboelectrically induced charge progressively increases, whereby the particles are highly charged upon emerging from the tube. The tube may be made of the same material as a minority component of the mixture to bring up the level of the charge on the majority component.

Electrostatic separation of mixed plastic waste

A system for estimating the burden of particulate levitated in a flow of gas which includes an upstream device for electrically charging the particulate, a downstream device for sensing the intensity of the field produced by the electrically charged particulate and an indicating device sensitive to an output of the downstream sensing device.

An interstitial tissue pressure measuring device comprising a cannula and a catheter, the catheter being adapted to pass through the cannula and the distal end of the catheter being provided with a plurality of longitudinal slits defining a plurality of petals between them. When the cannula is emplaced in an interstitial tissue site and the catheter is passed through the emplaced cannula into the tissue, the petals facilitate measurement of pressure by a pressure-sensing device at the proximal end of the catheter.
