The improved rotary cutter performs cutting by making a knife edge portion of a rotating disc-shaped knife (2) bite into a surface of a sheet (1) being successively fed. On the underside of the traveling sheet (1), a brush (4) consisting of rod-shaped brush elements is fixed on a backing table (3) between point A and point B over the entire region in the lateral widthwise direction of the sheet (1...

A chamber (76) for use in a rotating field to separate blood components. An inlet port (68) near one end of the chamber introduces blood into the chamber (76) for flow circumferentially about the rotational axis toward the opposite end of the chamber (76) for separation into at least one blood component. At least one outlet port (72) is juxtaposed next to the inlet port (68) near the one end of th...

A starting system for a vehicle which during starting can effect smooth starting and furthermore can convert into electrical energy and store in a battery excess kinetic energy accompanying the difference in speed between the engine and the driving wheels occurring during starting comprises: a gearbox (18), having at least a first gear element (5) connected to an output shaft (12) of an engine (11...

A device for delivering wound bobbins from a textile machine, comprising a main conveyor of wound bobbins, the conveyor having an end, an ancillary belt conveyor which receives wound bobbins from the end of the main conveyor and conveys them in a conveying direction; and a multi-story row container at one or both lateral sides of the ancillary conveyor.

The device moves the element relative to the thread movement. The element is connected to a drive motor via a drive mechanism. The mechanism contains parts (20, 22), which are relative turned, when the motor (19) is turned in a direction opposite to its normal direction of rotation. One part is coupled to the motor, the other part is locked against turning in reverse direction. Relative turning of...

The invention concerns a method for control of the properties of the remaining oil layer on magnesium or magnesium alloy particles and/ or other reactive metal particles produced from molten metal. The particles are cooled in a cooling oil with subsequent centrifuging and heating to remove remaining oil. A part of the oil layer on the particles is replaced with a lighter oil, preferably during cen...

An optical sensor apparatus receives visible light and converts that light to electrical signals for use by a control system. Visible light enters the apparatus through a hemispherical "fisheye" lens which provides a 360 DEG field of view in azimuth and a 180 DEG field of view in elevation. The light exiting the fisheye lens is projected through a shutter mechanism onto a receptor of a camera. Th...
