Eckart GmbH has been granted a patent for lustrous copper-based metal flakes that contain, in addition to 70-98% weight copper, at least one additional metallic alloy component comprised of 2% to up to 30% weight zinc and are produced via vacuum evaporating of the separate components and wherein each component of the alloy is evaporated separately, deposition of alloy metal films onto a carrier sheet, stripping of the films from the carrier sheet and subsequent comminuting
of the films wherein the flakes have plane-parallel surfaces and a thickness of between 20 and 60 nm.
Key statement: The rubber particles, at a room temperature below the glass transition temperature, are introduced into a comminuting
device concurrent with the introduction of an inert gas coolant at a temperature below about -75[degrees]F and are comminuted at a rate proportional to the average particle size of the introduced rubber particles to an average size within the range of crumb or powder rubber particles.
It tackles many issues that have largely escaped anthropological consideration such as refugees from Irian Jaya, sex work, plantation experiences, suburban comminuting
, or education.
They are particularly suitable for applications in food preparation as well as a wide range of general engineering applications involving blending, dispersing, emulsifying, suspending, solubilising, disintegrating, comminuting
, reaction accelerating, agglomerate reduction, homogenising milling or gelling, together with combined pumping and mixing.
But when comminuting
herbs for use in ointments or salves, an electric grinder gives a greater degree of fineness and uniformity.
