Two separators (17a, 17b) are provided on a bobbin creel in order to limit the balloon (13). The separators (17a, 17b) form two guide planes for the yarn (4) which form a two-sided limitation of the drawing-off space (20) in front of the bobbins (3). The drawing-off space (20) narrows from the end face of the bobbins (3) in the direction of run of the yarn.

A system for continuously separating lighter and intermediate density matter, such as plasma rich in platelets from whole blood moves blood through a diverging centrifugation gap (65) between inner and outer walls of a rotor (42) rotating about a central axis within an outer housing. The centrifugation action creates layered flow along an intermediate section. However by creating trailing wakes in...

In the production of tyres, particularly those for motor vehicles, the system for applying the beads has two horizontal guide tracks on at least one horizontal rail, the whole being mounted on a flat base, a mounting for a bead applicator, where the mounting is on the rail and has a centre hole through which the green tyre can be passed, a plate on the mounting with a vertical guide on each side, ...

The machine has spacers (10,11,23-29) which are rigidly attached on a stacking table (3). The spacers are separated in such a way that each of the differently formatted stack supports (12,30-33) lies on such a number of spacers that it is protected against tipping. The stack supports of smaller format lie on a smaller number of spacers than the supports of larger format. The spacers are in rod for...

A method and apparatus for the production of iron carbide in a shaft furnace, by reacting a carbon containing reducing gas as the process gas with particulate metal oxide material for an extended residence time at low temperature.

There is disclosed a method for welding plastic-coated metal comprising approximating the pieces to be welded, removing the coating from the welding site using a laser to heat it and then laser-welding the metal-to-metal contact at the welding site in the absence of the coating.
