Disclosed is a process for synthesizing high quality diamond, at high speed, in a gas phase using carbon monoxide and hydrogen gas as starting gases, which comprises adding an oxygen-containing inorganic gas such as CO2 under conditions where graphite is produced unless the oxygen-containing inorganic gas is added. Also, disclosed is a process for consecutively synthesizing diamond on a plurality ...

Smaller and larger fragments of tobacco ribs are sifted out of a mixture of tobacco ribs and tobacco shreds before the shreds are converted into a rod-like filler which is ready to be draped into a web of cigarette paper. The larger ribs are comminuted and are mixed with smaller ribs prior to readmission into the flow of shreds in such a way that the readmitted ribs are located in the inner portio...

A laying roller for textile yarns which, via a central air supply, supplies two air feed channels which are separated from each other. Each channel feeds air via a respective one of two porous sintered bearing bushings which are axially separated from each other. The air passing through the porous bushings builds up an air cushion for supporting a surrounding roller shell.
