Abstract: The invention relates to a method of producing silane or hydrochlorosilanes by disproportionation of a higher chlorinated hydrochlorosilane or a mixture of said hydrochlorosilanes in the presence of a catalyst. Before the catalyst is used, it is a) washed with hyper-pure water in one or several steps; b) transferred in the water-moist state to the reactor in which the disproportionation is to proceed; c) treated in the reactor with boiling methanol or rinsed with anhydrous methanol; and d) the methanol is removed from the catalyst by evacuation and/or stripping with inert gas. The invention further relates to a method for treating disproportionation catalysts.

Abstract: The present invention relates to a process for preparing trimethylolpropane having a low APHA color number.

Abstract: The present invention describes a method for the determination of the concentration of acrylic acid C1-C8 esters in fuel gas, with the following step: bringing the fuel gas containing acrylic acid C1-C8 esters into contact with palladium molybdate, so that a change in colour takes place.

Abstract: The present invention relates to the mixing of dental materials in a container and/or to the dispensing of a dental material or a mixture of dental materials from a container. In particular, the present invention relates to a dental material processing device such as a mixer and/or dispenser for mixing and/or dispensing dental material(s) from a container or in a container, respectively, a method of communication between a dental material processing device for mixing and/or dispensing dental material(s) and at least one separable information device, an information device for use in mixing and/or dispensing dental material(s) with a dental material processing device, and a system comprising a dental material processing device and at least one information device.

Abstract: The invention relates to an ultrathin semiconductor circuit having contact bumps and to a corresponding production method. The semiconductor circuit includes a bump supporting layer having a supporting layer thickness and having a supporting layer opening for uncovering a contact layer element being formed on the surface of a semiconductor circuit. An electrode layer is situated on the surface of the contact layer element within the opening of the bump supporting layer, on which electrode layer is formed a bump metallization for realizing the contact bump. On account of the bump supporting layer, a thickness of the semiconductor circuit can be thinned to well below 300 micrometers, with the wafer reliably being prevented from breaking. Furthermore, the moisture barrier properties of the semiconductor circuit are thereby improved.

Abstract: The invention relates to a device for storing and dispensing a flowable composition. Said device comprises a first (1) and a second film (2), a dispensing zone (4), a first chamber (5), containing a first substance (A) and a second chamber (6), containing a second substance (B). Said chambers are interconnected by a transition zone (3) that can be selectively opened. At least one of the films is deep-drawn in the region of the chambers and at least one of the films is pre-formed in the region of the second chamber, in such a way that once the device has been activated by opening the transition zone, the first substance can to a great extent be completely transferred to a second chamber, increasing the volume of said chamber as a result.

Abstract: Disclosed is an optical transmission system and module which includes a negative dispersion, dispersion compensating optical fiber coupled to a micro-structured optical fiber (such as band gap fiber, photonic crystal fiber or holey fiber) for compensating for the accumulated dispersion in a transmission fiber. The optical transmission system and module in accordance with the invention provides substantially equal compensation of total dispersion over an operating wavelength band, reduced overall system length, and lower insertion loss.

Abstract: Silane is produced in a continuous process by disproportionating trichlorsilane in at least 2 recreation areas for reaction/distillation, which are run through by a countercurrent of steam and liquid in the presence of catalytically active solid under a pressure which ranges between 500 mbar and 50 bar.
