Abstract: The pressure plate for a motor vehicle friction clutch comprises a clutch cover, a non-rotatable but axially displaceable presser plate and a diaphragm spring which is supported in the region of its external circumference on the presser plate and on a smaller diameter on the clutch cover. Securing elements retained on the clutch cover pass through openings of the diaphragm spring and hold the diaphragm spring between the two wire rings, of which the wire ring placed on the side of the presser plate is axially undulated. The regions of the wire ring which form undulation crests in relation to the diaphragm spring extend below the support faces of the securing elements. A projection is formed by bending or as additional part on the wire ring and fixes the wire ring non-rotatably.

Abstract: The invention provides a method for increasing the color density of a dyed fabric material of, especially, a synthetic fiber as well as the fastness of the color to rubbing and washing. The inventive method comprising (a) pretreating the dyed fabric material with an organopolysiloxane which is an amino-modified organopolysiloxane or a dimethylpolysiloxane, and then (b) exposing the thus pretreated dyed fabric material to low temperature plasma of an inorganic gas under a reduced pressure. The inorganic gas is preferably oxygen or a gaseous mixture containing at least 10% by volume of oxygen. The color-deepening effect is particularly remarkable when the color of the dyed fabric material is black to impart increased graveness and vividness of the color.

Abstract: A forage or picking harvester for the rough grinding of grain has a housing with a cylindrically shaped outer wall. A cutting blade wheel is located within the housing coaxial with the cylindrically shaped wall. The housing has an inlet and an outlet with a discharge duct forming the outlet and extending outwardly from the cylindrically shaped wall. Blades are mounted on the cutting blade wheel and extend radially of the axis of the wheel with the radially outer ends moving along a circle located at the inside surface of the cylindrically shaped wall. A comb-like arrangement of bearing arms is located within the discharge duct adjacent to the opening from the housing so that the blades on the cutting wheel hurl the grains against the bearing arms whereby the arms effect a rough grinding of the grain.

A crushing device is located within the discharge tube and is positioned to receive the material carried along the circumferentially inner surface of the housing by the disc wheel. The discharge tube forms an air transport duct located radially inwardly of the crushing device relative to the axis of the disc wheel chopper so that air flow generated by the disc wheel bypasses the crushing device and flows through the air transport duct for supporting the flow of material exiting from the crushing device.

Abstract: A hinge attachment arrangement for mounting a door on a motor vehicle includes a pair of hinge wings interconnected by a hinge pin with one hinge wing to be secured to a vehicle door and the other to a fastening element secured to the door frame on the vehicle.
