Patent DE-3365609-D1 (DE)
Title: A method of recovering heat from moist gas by water vapor absorbtion and a plant for carrying out the method
Inventor: SVEDBERG UNO GUNNAR
IPC: B01D53/26
Filed: 1983-05-19
Granted: 1986-10-02
Abstract: The invention relates to a method and plant for providing heat recovery from hot and moist gas by water vapor absorption. The hot and moist gas, e.g. a flue gas is led in through a flue gas duct (1) to a chamber where the flue gas is washed in a filter (3) sprayed with water, whereby the gas is also cooled so that the heat from cooling is used for vaporizing a part of the water. In this state the gas is brought into contact with a hygroscopic solution (17) through an absorption zone (16) in an absorption tower (15). After treatment, the gas is taken through a flue gas outlet (18), the hygroscopic solution which was supplied with water vapor being taken to a section for vaporization by means of a vaporizer (26) to which heat (27) is supplied. The latent heat coming from the vaporization is converted in the heat exchanger (33) so that it may be utilized. The concentrated part of the hygroscopic solution is merged with the non-concentrated part and taken (21) to a further heat exchanger (23) for recovering (35) heat for utilization, and subsequently refluxed back into contact with flue gas in the absorption tower (15).

Title: Process for treating metals by using dies
Inventor: GSTETTNER MANFRED
IPC: B22F3/14
Filed: 1983-12-22
Granted: 1988-05-05
Abstract: The weapon barrel comprises a liner and at least one jacket tube. The liner is made of a highly wear-resistant material, like a cobalt or nickel base alloy, and the jacket tube is made of a tough alloy, like steel. In the manufacturing process the liner material is packed into the jacket tube in the form of a powdery material which may be pre-pressed or pre-sintered. The packing is arranged such as to leave a central free space in the jacket tube, and the jacket tube may be surrounded by an encapsulating tube. The jacket tube or the encapsulating tube is closed either before or after evacuation, and the closed tube arrangement is subjected to a combined heat and pressure treatment at temperatures of at least 900 DEG  C., but below the melting point of the relevant materials and at pressures of at least 900 bar. The compound body thus obtained is formed with a full-area metallic bond between the liner and the jacket tube. After eventual heat treatment the compound body is further machined and a rifling is worked thereinto as, for example, by forging.

Abstract: An expansion dowel assembly includes an axially elongated anchor bolt and a pair of serially arranged expansion elements or shells into which the anchor bolt is drawn. The anchor bolt has axially extending conically shaped expansion members spaced apart in the axial direction and each is arranged to be drawn into a different one of the expansion elements. The expansion member closer to the leading end of the anchor bolt has a larger cone angle than the other expansion member. The expansion elements are interconnected by a web so that the expansion elements are axially displaceable relative to one another. When the anchor bolt with its expansion members is drawn into the expansion elements, initially the trailing expansion element is widened or expanded. Subsequently, after a predetermined axial movement of the leading expansion element toward the trailing expansion element, the widening of the leading expansion element is commenced.
