Patent number: 8951642Abstract: An aqueous two-component aqueous dispersion adhesives, including in particular polyether-polyurethane polymers and ethylene vinyl acetate copolymers (EVA) having a glass transition temperature of greater than 0° C. The dispersion adhesives are optimally suited for use as contact adhesives, and for gluing plastic membranes. It has been demonstrated that the adhesives or the adhesive composite items produced therewith are characterized by an exceptionally low plasticizer absorption behavior, and contact adhesion. The good heat resistance and good bonding to various bases are also advantageous.Type: GrantFiled: October 12, 2010Date of Patent: February 10, 2015Assignee: Sika Technology AGInventors: Martin Demmig, Andre Buchholz, Christina Bosse, Tino Bendkowski

Patent number: 8778131Abstract: This invention relates to a process for sealing an above-ground or underground structure. It involves in particular the use of non-reactive dispersion adhesive compounds. This process in particular has the advantage that good and long-lived adhesion can be achieved very quickly, and that in particular the non-reactive dispersion adhesives that are used have a small tendency to absorb the plasticizers present in the PVC sealing film, so that as a result this process is best suited to assure long-lasting adhesion of PVC films with various substrates.Type: GrantFiled: December 14, 2011Date of Patent: July 15, 2014Assignee: Sika Technology AGInventors: Martin Demmig, Andre Buchholz, Christina Bosse, Martin Linnenbrink

Patent number: 8608197Abstract: An airbag module for a motor vehicle is provided. The airbag module comprising a gas bag, which is inflatable by means of a gas generator for the protection of a person, and a vent opening through which gas originating from the airbag module can escape, and a device for controlling the outlet cross-section of the vent opening, which comprises at least one covering member with which the vent opening can be covered, in order to at least partly close the same, and which furthermore comprises an actuating mechanism which cooperates with the covering member, in order to vary the outlet cross-section of the vent opening. The actuating mechanism includes a gas source and an element inflatable by means of the gas source, which during inflation cooperates with the covering member such that it effects a change in the outlet cross-section of the vent opening.Type: GrantFiled: December 12, 2012Date of Patent: December 17, 2013Assignee: Takata AGInventors: Nick Eckert, Frank Wollny, Andre Buchholz, Axel Heym, Matthias Böse, Rolf Lazar, Marc Prost-Fin, Thomas Hofmann, Tobias Fechner
