Abstract: A film composite folded from a single film to form a plurality of layered film layers (1) and comprising microfluidic structures (5) in different planes, wherein the microfluidic structures are formed by film layers having embossed recesses covered by the respective film layer adjacent in the layering direction, and wherein microfluidic structures of one plane are connected to microfluidic structures of another plane via through-holes in at least one film layer; a method for producing the film composite; and the use of the film composite.

Abstract: A hair moisturizing topical composition comprising materials that emit electromagnetic radiation at wavelengths that affect tertiary structure (breaking of disulfide bonds) in human hair, and that bring about changes in secondary structure of hair proteins. The intensity of the radiation is controlled and sufficient to cause or facilitate altering of protein structure. The invention includes methods of using such topical compositions. Testing indicates that the level of tightly bound water in hair is increased, and there is no damage to hair of the type characteristic of heat and chemical treatments.

Abstract: A method for removing transition metal stains from biological samples including protein, DNA, and RNA has been found. In particular, a hydrogen peroxide mediated silver stain removal method for PAGE gels is disclosed which is safer, more effective, and more convenient than other methods of the prior art. This silver destaining method is compatible with mass spectrometry analyses of in gel digested PAGE gels.

Abstract: An electronic device for a motor vehicle, having an electronics unit designed for switching high currents in a two-part housing, a capacitor unit being arranged in the housing to suppress the interference signals produced by said high currents. In an electronic device which is easy to manufacture and in which the heat produced by the electronic circuits has no further effect on the operation of the electronic circuit, the capacitor unit, which is designed to have a large surface area, is thermally connected to a first housing part (1), and the electronics unit (8, 9) is thermally connected to a second housing part (2).

Abstract: An integrated optical Mach-Zehnder interferometer has two arms (11, 12) having different geometric path lengths. A first arm 11 includes arcuate segments (113, 114, 115, 116) and linear segments (111, 112) and the second arm 12 includes a mirror image arcuate segment (123, 124, 125, 126) for each arcuate segment of the first arm 11 and the total length of the straight segments (121) of the second arm 12 is less than the total length of the straight segments (111, 112) of the first arm 11. The integrated optical Mach-Zehnder interferometer is used as a demultiplexer with a 2.times.2 coupler at the output and as a multiplexer with a reversed beam path. The phase difference of both arms is directly proportional to the difference of the geometric path lengths.

Abstract: Integrated optical branching arrangement has a monomode waveguide 1 and a Y-branch waveguide 2. The waveguides conjointly define an abutting junction having a lateral offset (d). This is particularly advantageous when curved monomode waveguides are used. The offset is suitable for setting the power distribution ratio. The integrated optical branching arrangement can be applied to ion-exchanged devices in glass and to wavelength multiplexers.

Abstract: The invention is directed to an integrated (2.times.2) optical coupler including input waveguides (21, 22) approaching each other at an angle .PHI. and having different propagation constants and widths (w.sub.1, w.sub.2), minimum web widths S (approximately 4 .mu.m) and output waveguides (23, 24) of the same width w.sub.0. The output waveguides include circular arc segments which connect to the respective input waveguides with abrupt steps. Both directions are the same. Attenuation is avoided where the waveguides come close to each other in the interaction region and arcuate segments in the narrow waveguide 21 are avoided. The optical coupler according to the invention can be used in branching devices and especially in a 2.times.N branching device and in Mach-Zehnder duplexers.
