Title: Process for the purification of chlorosilanes
Inventor: MATTHES REINHARD DIPL CHEM DR
IPC: C01B33/107
Filed: 1981-10-07
Abstract: The present invention relates to the purification of chlorosilanes. According to the claimed process, not only traces of boron compounds can be removed from the chlorosilanes, enabling them to be used for the direct preparation of semiconductor silicon, but also traces of impurities of heavy metals. The removal of these heavy metal traces is of particular importance in the purification of tetrachlorosilane to be used for the production of optical fibres. According to the claimed process, the chlorosilanes are brought into intimate contact with compounds having an Si-O-Si grouping in the presence of small amounts of hydrogen halide, and the chlorosilane is then distilled off. The compounds containing an Si-O-Si grouping include, according to the invention, chlorosiloxanes and finely divided SiO2. These compounds can also have been produced in situ by adding hydrochloric acid to the chlorosilane.

Title: Device for actuating a hydraulically-actuated shut-off member in a sewer line
Inventor: WEILER WALTER
IPC: E03F7/04
Filed: 1982-01-26
Abstract: A shut-off member, which is arranged as a backflow preventer in a sewer line, is actuated by means of compressed air which is held ready in a pressure vessel pressurised by the water line network. A backflow indicator controls the release of the compressed-air supply to the shut-off member and also, after cessation of the backflow, the depressurising of the shut-off member, the discharging of the water which has subsequently flowed into the pressure vessel and optionally the provision of a new compressed-air cushion. The supply of mains water to the shut-off member is prevented by a sufficient level difference in the pressure vessel and/or by a separating membrane and/or a float-controlled shut-off valve. A simple and reliable actuating device which works without external energy by using the water line pressure which is always available is provided, but without any risk of transmitting dirt or germs to the drinking-water system.

Title: Hollow rope
Inventor: MENTSCHEL DIETHARD
IPC: D07B1/12
Filed: 1982-11-04
Abstract: The hollow rope consists of a braided structure composed of intersecting cords and surrounding a rope channel. The cords of the hollow rope are joined together, preferably welded together, at at least one end to form a tip which can be inserted through the braided structure into the rope channel, with the result that a tension-resistant connection of the inserted rope end to the braided structure is obtained. To make the rope elastically stretchable under tension, for example when it is used as a tow rope, there is arranged in the rope channel a portion of an elastically flexible strand, the diameter of which is larger than the clear diameter of the rope channel when the rope is in the extended state. A plurality of ropes of this type can form a toy for assembling different figures.
