摘要:
Heat-vulcanizable adhesives for the bonding of solids, the adhesive contains polybutadiene or a polybutadiene mixture and/or copolymers of butadiene with ethylenically unsaturated monomers and other vulcanizable components, and at least 0.5% by weight (based on the weight of vulcanizable components) of a metal salt as a hardening catalyst. The adhesive is particularly useful in vehicle assembly. The adhesive in less than 5 hours exposure to air forms a protective skin which imparts washer resistance to the adhesive.
摘要:
Heat curable adhesives, based on polybutadiene containing hydroxyl groups, which have a content of (a) polybutadiene having a number average molecular weight of from about 1000 to 3500 and OH values in the range from about 20 to 100; (b) blocked multi-isocyanates, (c) sulfur and (d) conventional vulcanization accelerators, an which may also contain conventional, especially mineral, fillers, pigments and/or auxiliaries, show good elasticity behavior and high tensile shear strength after curing and have a relatively low viscosity favorable for processing before curing.

In an anti-skid device having lengths of chain which can be thrown under a vehicle wheel by means of a rotary plate which is arranged at the end of a pivotable extension arm (5), a drive unit having a piston (16) which is arranged in a cylinder (11) and whose movements are transmitted by a thrust chain (22) which assumes the function of the piston rod, to a drive pinion (29) whose shaft bears the extension arm (5) is used to apply the pivoting movement to the extension arm (5).
摘要:
A bearing mechanism for a transverse leaf spring that can be mounted in the region of an axle of a vehicle. The bearing mechanism has an outer bearing shell device and insertion devices which are at least partially encompassed by the outer bearing shell device and comprise layer elements with different stiffnesses. In the assembled state, the insertion devices are each disposed between the outer bearing shell device and the transverse leaf spring. In the region of a support surface of the transverse leaf spring, a recess is formed for each of the insertion devices in which the insertion devices engage in a form-locking manner. The insertion devices are each formed in the contact surfaces facing the support surfaces of the transverse leaf spring, having at least one receiving device into which, in the assembled state of the insertion devices, a region of the transverse leaf spring engages.

A towing device, for a towing vehicle, with a coupling shaft attached to the towing vehicle, a ball head mounted on the coupling shaft so that the ball head can rotate about a vertical axis, which can be coupled to a coupling counterpart of a trailer vehicle, and with an angle-measuring device by which rotation of the ball head about the vertical axis, relative to the coupling shaft, can be determined, and a force-measuring device by which force exerted by the ball head on the coupling shaft in the direction of the vertical axis can be determined.
摘要:
Metal compounds of the formula I, where M is selected from among Ni and Pd in the oxidation state +II can be used for the polymerization or copolymerization of olefins. Supported catalysts for the polymerization and copolymerization of olefins can be obtained by application of one or more of the above-described ionic metal compounds to a support.
摘要:
According to the invention, an elastic sealing foil for an inside door panel of a motor vehicle door is formed to provide a receiving device which can be changed from a manufactured position into an installed position. In the manufactured position, the receiving device is composed of two formed-out portions which are arranged above one another, have a cross-section with an approximately U-shaped profile and extend in the opposite directions. These formed-out portions are connected to one another by way of a common wall section. In the installed position, the receiving device projects through an opening of the inside door panel, and downward into the hollow space of the door body, and envelopes an audio or accessory part inserted into the receiving device, providing a water-tight seal with respect to the hollow space of the door body. The receiving device can be displaced from its manufactured position into its installed position by applying an outwardly and downwardly directed force to the lower formed-out portion.
摘要:
A method of manufacturing alkyloligoglycosides. Alkyloligoglycosides and alkylglycosides having alkyl groups with 8 to 24 carbon atoms, which are of interest in home economics and in the cosmetics industry, can be manufactured by glycosidation and transglycosidation. Light-colored alkyloligoglycosides and alkylglycosides are manufactured from saccharides and alcohols by glycosidation and transglycosidation with the addition of polar polymeric complex-forming agents, and by bleaching of the final products with peroxides.
摘要:
A process for producing aliphatic nitriles by reacting the corresponding carboxylic acids or carboxylic alkylesters with ammonia in the liquid phase and in the presence of a metal-containing catalyst, the reaction being carried out at a temperature between about 150.degree. and 290.degree. C. in the presence of iron or an iron compound as the catalyst.
