Abstract: A device for applying a directed contact pressure force to a multitude of samples. A first part of the device includes a multitude of sample receptacles that receive a multitude of joining surface modules of the same kind, and a second part of the device is connected to the first part in such a manner that a multitude of fluidically intercommunicating hydraulic cylinders in one of the two parts can load the joining surface modules simultaneously in a loading direction at a predetermined force that is substantially identical in respect to all samples.

Abstract: An adapter set for fluorescent lamps with electronic ballast for converting to a fluorescent tube having a smaller diameter. The electronic ballast and the end cap adapter each on one axial front thereof comprise contact pins having dimensions of fluorescent tubes of larger diameters, and on the opposite axial front have contact sockets for receiving two contact pins of the fluorescent tube having a smaller diameter. Preferably, the electronic components of the ballast are located on at least two spatially separated partial circuit boards which may be connected to each other by a flexible contact strip. A jacket tube has at least one cable channel that extends axially relative thereto to house the wiring connecting the contact pins of the end cap adapter and the electric ballast.

Abstract: The invention relates to an adapter set for fluorescent lamps with electronic ballast (7) for converting to a fluorescent tube (8) having a smaller diameter by way of two adapters (6, 7), which are produced by the electronic ballast (7) and by an end cap adapter (6), characterized in that the electronic ballast (7) and the end cap adapter (6) each on one axial front thereof comprise contact pins (1a, 6a) having dimensions of fluorescent tubes with greater diameters, such as T8, and on the opposite axial front have contact sockets for receiving two contact pins of the fluorescent tube (8) having a smaller diameter, such as T5. It is preferred that the electronic components of the ballast (7) are located on at least two spatially separated partial circuit boards (7a, 7b, 7c, 7d), however which are electrically connected to each other by flexible contact strips (7e).

Abstract: The present invention relates to a multilayer product (composite material), wherein the first layer is a layer which is optically dense in the infrared range, and wherein the second layer contains a polymer (plastics) as substrate. The invention additionally relates to a method of improving the flame resistance of mouldings made from polymers and to a method of producing the multilayer products as well as to components which contain the above-mentioned multilayer products.
