Abstract: A system for controlling a parking brake for a motor vehicle includes a first operator control arrangement and a control unit. The control unit puts the parking brake into a disengaged position by actuating a first electrical actuator when it recognizes a release request on the first operator control arrangement. In order to release the parking brake at least in the event of a fault in the first operator control arrangement and/or in the first electrical actuator, provision is also made for the control unit to put the parking brake into the disengaged position by actuating a second electrical actuator, which is independent of the first electrical actuator, redundantly when it recognizes an emergency release request on a second operator control arrangement.

Abstract: An emergency release device for the parking lock of a motor vehicle is described which contains an locking device (46,44,38,24,12,10) that is pressed into its engaged position by a spring element (42,50) and which can move into its disengaged position by at least one actuator (46) that is actuated by a control element (56,58) against the spring force. The locking device (46,44,38,24,12,10) can be linked with a clutch pedal located on the operator's station by releasable mechanical connecting elements (108,110,112), in such a way that it is possible to emergency-release the parking lock in case of vehicle malfunction.

Abstract: Die for granulation presses, particularly for the manufacture of feed granulates, consisting of a cylindrical, cross-sectionally circular center element (1) having a plurality of granulating bores and connecting flanges (2,3) formed on the two ends of the center element, whereby the center element (1) and the connecting flanges (2,3) consist of separate elements. The center element (1) is made of wear-resistant steel and the flanges (2,3) are made of a highly durable steel. The connecting flanges (2,3) are heat shrunk onto the ends of the center element (1).

Abstract: Halogen-containing phosphoric acid polyesters of the general formula (I) ##STR1## IN WHICH R stands for an alkylene radical or a halogen-substituted alkylene radical having from 2 to 6 carbon atoms, a --CH.sub.2 CH.sub.2 --O--CH.sub.2 CH.sub.2 -- radical, a phenylene or an alkyl or halogenoalkyl-substituted diphenylenemethane radical, and R.sub.1 stands for a branched or unbranched alkyl radical having from 6 to 18 carbon atoms.

Abstract: Flameproof moulding compositions, which are based on polyolefins and made from a pulverulent blend comprising a polyolefin as its essential ingredient and a plurality of flame-retardant ingredients. The flame-retardant ingredients comprise red phosphorus and at least one organic nitrogen compound which carbonizes after inflammation. The moulding compositions contain the flame-retardant ingredients in a total proportion of at most about 30 weight %. Red phosphorus and organic nitrogen compound are used in a quantitative ratio between 99:1 and 1:99.

Abstract: Improved flameproof moulding compositions, which are based on polyolefins and made from a pulverulent blend comprising a polyolefin as its essential ingredient and a plurality of flame-retardant ingredients. The flame-retardant ingredients comprise red phosphorus and at least one organic nitrogen compound which carbonizes after inflammation. The moulding compositions contain the flame-retardant ingredients in a total proportion of at most about 30 weight %. Red phosphorus and organic nitrogen compound are used in a quantitative ratio between 99:1 and 1:99.The improved moulding compositions contain as a stabilizerA. between about 1 and 10 weight % of amidosulfonic acid or ammonium bisulfate, based on the total quantity of the flame-retardant ingredients, orB. between about 5 and 15 weight % of a paraffin oil having a density between about 0.83 and 0.88 g/cc and a viscosity between about 15 and 380 centipoises, or of a mineral oil boiling within the range 170.degree. and 350.degree.
