Patent DE-3104360-A1 (DE)
Title: Device and process for leading a supply line through a masonry structure
IPC: F16L5/02
Filed: 1981-02-07
Abstract: The invention relates to a device for leading a supply line through a masonry structure. The device exhibits first of all a protective tube, which can be inserted into a masonry-structure bore of predetermined diameter, and a device for supporting the protective tube on the supply line. The space between protective tube and masonry-structure bore can be filled by a sealant. The protective tube is provided with a guide ring which is arranged at a distance from the outer end of said tube and by means of which the protective tube can be guided in the masonry-structure bore. A filling tube passes through the guide ring, which tube is arranged in the annular space between protective tube and masonry-structure bore and, in the region of the inner end of the protective tube, can be connected to a sealant pump. The sealant is pressed, under superatmospheric pressure, via the filling tube into the space which is directed towards the outside of the masonry structure and is located in front of the guide ring. Outside, in front of the masonry structure, the sealant thus forms a sealing plug which is widened in diameter, effects secure sealing and ensures that gas which is released even outside in front of the masonry-structure lead-through point, or liquid which is released or is located there, does not penetrate via the masonry-structure bore into the masonry structure and into the building of which the masonry structure forms a part. <IMAGE>

Title: Converter sail
Inventor: KOENIG FELIX VON DIPL ING
IPC: B63H13/00
Filed: 1981-06-29
Abstract: In shipping, on account of the high fuel costs, attempts are again being made as far as possible to use wind energy as secondary or main drive power. The conventional sail is only adequate for tonnages up to 5000 BRT. In addition, a large number of sailors are required to operate it. These sailors are neither available nor affordable. Suitable alternatives are the Flettner rotor, the rigid aerodynamic sail or the statically risky large wind wheel, by means of which the ship can also be sailed against the wind via the generation of current. Corresponding experimental ships are undergoing trials. According to the invention, the hazardous large wind wheel is to be replaced by an adopted sail area which is subdivided into many sections. A high-speed wind-energy converter with a generator, the power of which drives the ship's propeller, is accommodated in each section. The advantages of the converter sail are inexpensive mass wind wheels with minor static requirements, high storm-force strength, low manufacturing costs, adaptation of the wind power to the wind strength or the power requirement of the ship by switching individual wind wheels on and off, unmanned operation, two to three times the power compared with canvas sails, and an increase in the ship size to 10000 to 15000 BRT. <IMAGE>
