Abstract: An arrangement comprises a housing, in particular of a cooling and/or freezing device, a door which is articulated to the housing so as to be pivotable about a pivot axis of a hinge, and at least one drive device for pivoting the door relative to the housing, with the drive device comprising a drive unit by means of which a moment is exertable on the door relative to the hinge axis via at least one force transmission means.

Abstract: A device for grounding electrical components arranged in a chain has a grounding point at ground potential and an actuation device connected to the grounding point for connecting the electrical components to the grounding point. In order to provide such a device, with which a simple, safe, and durable grounding is obtained, the actuation device is constructed as a moving part extending in a longitudinal direction and movable in a longitudinal direction. The moving part has an electrically conducting grounding section connected to the grounding point and an electrically nonconducting insulating section arranged on the end of the moving part facing away from the grounding point.

Abstract: A screwing station, in particular along an assembly line, comprises at least one machine frame and a screwing tool adjustably supported relative thereto between at least one retracted and one operative position and connected to a supply and, optionally, a measuring line. To improve a screwing station of this type in such a way that less mass has to be moved while the screwing station is of a simple construction, so that wear, maintenance work and energy consumption are reduced and a concurrent movement of supply and measuring lines is prevented at the same time, which might otherwise result in damage to the lines, the screwing tool comprises a drive shaft supported on the machine frame and a wrench head telescopically displaceable relative to said shaft, the drive shaft and wrench head being drivingly connected and the wrench head being movable by means of a lifting and lowering means between retracted and operative position.

Abstract: The invention relates to an active impact protection system (1) for a knee area and/or a lower leg area of a vehicle occupant in a motor vehicle, particularly in a passenger car. The impact protection system (1) comprises an impact element (2) that can be extended toward the vehicle occupant out of a passive position and into an active position by means of a drive device (4). A particularly advantageous design results when the impact element (2) is formed by a lid of a passenger-side glove compartment (3).

Abstract: A process for preparing a shell-type catalyst which comprises applying to a substantially nonporous inorganic support material having a BET surface area of <80 m2/g, a catalytically active outer shell of a suspension containing at least one water soluble noble metal compound and a substantially water insoluble coating compound, drying the suspension onto the support material, and activating the coated support material in a reducing gas stream.

Abstract: The invention relates to a method for continuously or discontinuously producing tetrahydrofuran polymers by homopolymerization of tetrahydrofuran, alkyl-substituted tetrahydrofurans and/or alkylene oxides in the presence of carboxylic acid anhydrides or compounds containing reactive hydrogen using an optionally non-acidified or acid-activated calcined and granular natural amorphous aluminum silicate catalyst. The inventive method provides a means for substantially suppressing the formation of cyclic ethers and for obtaining a polymer with a narrow molecular weight distribution by keeping the concentration of carboxylic acid anhydrides or alkylene oxide constantly below 1 wt. % during polymerization. The catalysts have a long life span and lead to polymers that are characterized by highly uniform properties and a narrow molecular weight distribution even if a fairly impure monomer is used.

Abstract: A thermoplastic trim strip is mounted to an edge face of a wood-core furniture panel by applying a face of the trim strip directly to the edge face and bonding the trim-strip face directly to the panel-edge face. The panel has outer faces terminating at the edge face and the trim strip is provided with edge lips that project past the broad faces when the strip is bonded to the edge face. The edge lips are melted over onto the panel faces and trimmed off where they project past the panel faces. A thin layer of glue can be applied between a face of the trim strip and the edge face and the trim-strip face is bonded to the panel-edge face by means of the glue layer.

Abstract: An improved process for the preparation of polytetramethylene ether glycol diesters of the formula R—CO—O(—CH2-CH2-CH2-CH2-O)n-COR1 in which R and R1 are identical or different and are an alkyl radical or a derivative thereof, by polymerization of tetrahydrofuran in the presence of a fixed-bed polymerization catalyst and a carboxylic acid anhydride. Through use of neutral or weakly basic magnesium-aluminium hydrosilicates instead of the known acidic montmorillonite, zeolite or kaolin catalysts, polymers with more uniform properties and a narrower molecular weight distribution are obtained at a higher rate of polymerization, even when technical-grade tetrahydrofuran is used.

Abstract: An improved process for preparing quinolone- and naphthyridonecarboxylic acids and esters thereof from benzoyl chlorides and nicotinoyl chlorides, respectively, in which the reaction carried out in the presence of a non-polar to slightly polar solvent without separation of intermediaries that form during the process.

Abstract: The molecular weight distribution of polytetrahydrofuran and copolymers of tetrahydrofuran with alkylene oxides is narrowed down by blending the polymers with a mixture of an alicyclic compound, methanol and water at a temperature ranging from 0-40° C. The two phases formed are separated at 40-80° C., and polymers with low molecular weight distributions are isolated therefrom.
