Abstract: The invention relates to a turbulator (1, 10) for a channel (21, 23, 31, 42) of a process apparatus (30, 41, 44), in particular a heat exchanger, reactor or mixer, with a plurality of ribs (3, 14, 15), wherein at least one row (12, 13) of ribs (3, 14, 15), which define a common rib plane, is arranged, preferably uniformly, distributed and is, preferably uniformly, spaced apart from one another via gaps (4, 18, 19) in the longitudinal extension of the turbulator (1, 10). In order that the dead volumes and therefore the average residence times can be reduced by proportions that are not utilised or are utilised less efficiently for the process in order to keep the respective process medium in a defined and preferred operational state as far as possible over the entire residence time, it is provided that on at least one longitudinal end of the turbulator (1, 10) a hook element (6, 20) is provided for positively hooking a tool (7) to remove the turbulator (1, 10) from the channel (21, 23, 31, 42).

Abstract: Sprayable low-viscosity rubber damping compounds based on liquid rubbers or elastomers and vulcanization agents, which contain small quantities of structure-reinforcing fiber fillers, are notable for the absence of previously usual solid rubbers and have a very low viscosity in the application state. Acoustic compounds of this kind are sprayable with the aid of fully automatic application systems, and are preferably processed at the basic body stage in vehicle construction.

Abstract: A stacked plate chemical reactor in which simple plates are stacked together to form the reactor. When openings in adjacent plates are properly aligned, fluid pathways and processing volumes are defined for chemical reactants, heat transfer medium, and a product. In one embodiment of the invention, an n-fold internal array is achieved by providing a first group of simple plates defining a reaction unit that includes bypass fluid channels and reaction fluid channels for each reactant, such that a portion of each reactant is directed to subsequent groups of simple plates defining additional reaction units. A chemical reactor with variable output is obtained in a preferred embodiment by reversibly joining reactor stacks comprising irreversibly joined reaction units, these reaction units consisting of a plurality of simple plates.

Abstract: Binder compositions based on vulcanizable rubber materials containing liquid polyenes, optionally solid rubbers and/or thermoplastic polymer powders as well as vulcanizing agents are suitable for the production of multilayer laminates consisting of two outer metal sheets and an intermediate binder layer. This intermediate layer may optionally contain in addition incorporated sheet material of synthetic fibers and/or metallic expanded meshes, wire meshes and the like.

These compositions are suitable as joint-sealing and sealing compositions, as underseal adhesives and as structural adhesives such as e.g. lap-joint adhesives.

Abstract: Heat-curing, expanding mouldings based on solid polybutadiene rubber and vulcanization systems free from elemental sulfur are distinguished by the following advantageous properties: in the uncured state in which they are supplied, they have minimal rubber-elastic resilience and are readily formable. During the curing process, no unpleasant odors are given off and, after curing, a soft and elastic foam with a continuous outer skin is formed.

Abstract: One-component hot-curing structural adhesives based on liquid rubbers, which may optionally contain functional groups, solid rubbers, thermoplastic polymer powders and sulfur and also vulcanization accelerators are suitable for bonding metal parts. Tensile shear strengths of more than 15 MPa and high breaking elongations of more than 15% can be obtained. These adhesives are substantially free from low molecular weight epoxy resins and are particularly suitable for use in white-shell assembly in the car industry.

Abstract: Hot-curing, foamable reactive compositions based on natural and/or synthetic rubbers containing olefinic double bonds, vulcanizing agents and blowing agents with a high percentage content of sulfur give foamed rubber compositions exhibiting high structural strength and high volume expansion. These compositions are suitable as multifunctional filling materials for hollow structures or hollow profiles in vehicle or machine construction. At one and the same time, they perform a sealing function, damp acoustic vibration and stiffen the hollow structures to a considerable extent.
