Abstract: The invention relates to a telescoping pull-out device for household appliances and furniture, especially a pull-out system for an oven. The telescoping pull-out device includes a first telescoping rail mounted in such a way that it can be displaced between a retracted position and an extended position. The telescoping pull-out device operates in a manner which prevents an uncontrolled and/or undesired automatic extension of the telescoping rail. The telescoping pull-out device includes a catch element for catching the first telescoping rail in the retracted position.

Abstract: A load hook arrangement includes a carrying element for the load, which is pivotable between a dosed position and an open position, a first blocking element, which is pivotable between a blocking position for blocking the carrying element in its closed position and a releasing position for allowing the carrying element to pivot into its open position, and a pivoting mechanism for pivoting the carrying element into its open position, wherein the load hook arrangement further includes a second blocking element, for blocking the carrying element in its closed position. This second blocking element can be in particular a magnet brake acting on the pivoting mechanism. Furthermore, the load hook arrangement can include a third blocking element for blocking the movement of the first blocking element. This third blocking element can be in particular an eccentric.

Abstract: The instant invention relates to new metathesis oligomers which are substituted with fluorinated groups. Also disclosed is a polymerisable composition comprising a catalytically effective amount of a penta- or hexavalent ruthenium or osmium carbene catalyst, the process for preparing the metathesis oligomers by applying the reaction conditions of Ring Opening Metathesis Polymerisation (ROMP) to the polymerisable composition. These new methathesis oligomers are useful for increasing the oil and water repellency of organic materials.

Abstract: A process is described for the preparation of olefin polymers by polymerization over a transition metallocene catalyst with the addition of at least one phosphorus(III) compound, sterically hindered amine, sterically hindered phenol or acid scavenger, alone or in combination with one another; the polymers which can be obtained in this way are of outstanding stability.

Abstract: The invention relates to a process for the preparation of olefin polymers by polymerization using a transition metal catalyst with the addition of an aminoalkyl-1,1'-biphenyl-2,2'-diylphosphite or aminoalkyl-2,2'-alkylidene-bis(phenyl)phosphite, in conjunction with optional further modifiers. The polymers obtainable in this manner have excellent long-term stability.

Abstract: A pusher rod extends lengthwise through the eccentric shaft. An additional disk clutch is located inside of the flywheel, which disk clutch is connected to a shaft section, which engages the pusher rod via a screw thread connection. This allows the drive of the punching press to translatorically shift the pusher rod via the further disk clutch. The pusher rod operates the movement of a locking pin, which locks the eccentric shaft to the eccentric bushing by a corresponding translatoric movement. The pusher rod operates furthermore a braceable coupling disk which transmits the driving force from the eccentric shaft to the drive apparatus of the workpiece feed drive. In order to operate these control units when adjusting the stroke of the press it is merely necessary to operate the machine drive in one or the other sense of rotation causing a corresponding closing or opening of clutches and locking members.
