Abstract: The structural carrier assembly is installed in a motor vehicle front or rear end. The structural carrier assembly includes one or more support brackets connected to one or more frame rails of a motor vehicle body. The structural carrier assembly further includes a carrier member having laterally positioned attachment clips. The attachment clips connect the carrier member to the support brackets. The carrier member includes one or more attachment mounts or locations for supporting accessories, such as engine accessories, of the motor vehicle. A cross frame is mounted to an upper end of the carrier member by welds or mechanical attachments. The attachment clips each include an integral fulcrum cup and locking tab typically formed on the lateral sides of the carrier member. The locking tabs engage mating openings formed in the support brackets to connect the carrier member to the frame rails.
Abstract: The present invention relates to a method of using foam to remove pollutants and/or heavy metals from a flowable media. The method may include providing a foam that may include cavities wherein the cavities may include an adsorbent composition of iron oxyhydroxy granules. The iron oxyhydroxy granules may have a BET surface area of >100 m2/g and a mean particle size of 0.1 mm-2 mm. The method may further include passing a flowable media containing pollutants and/or heavy metals through the foam wherein the pollutants and heavy metals may be removed from the flowable media by the iron oxyhydroxy granules. A method of manufacturing the foam is also disclosed. The method may include introducing an adsorbent composition into a liquid reaction composite to form a mixture and adding an isocyanate reaction component to the mixture to form the foam.

Abstract: A method of connecting (fixedly joining/attaching) a shaped metal part and a shaped thermoplastics part together is disclosed. The method includes: (a) contacting a surface of the shaped metal part with a surface of the shaped thermoplastic part, thereby forming a contact region; and (b) melting a portion of the shaped thermoplastic part in the contact region by irradiating the shaped metal part with a laser (e.g., emitting a laser beam), thereby fixedly joining the shaped metal part and said shaped thermoplastic part together. Also disclosed is a plastic/metal composite article prepared by the method of the present invention.
Abstract: The present invention relates to a process for the production of a catalyst by reacting metal compounds with azo ligands, the catalyst, the use of this catalyst as a polymerization catalyst, a process for olefin (co)polymerization with the aid of these catalysts, reaction products of these catalysts with co-catalysts, the olefin (co)polymer, the use of this olefin (co)polymer for the production of molded parts and also molded parts produced from the olefin (co)catalyst.
Abstract: The invention describes a method of use of a conveying apparatus for the pneumatic conveyance of sized glass fibers, the sized glass fibers having a size extractability of at most 85%, preferably at most 50% and with particular preference at most 40%.
