Title: Method and means for cleaning a seal for a moving rod guided in the housing of a fitting
Inventor: MIETH HANS OTTO DIPL ING
IPC: F16K41/04
Filed: 1985-07-12
Abstract: The invention relates to a method and a means for cleaning a seal for a moving rod guided in the housing of a fitting, in particular for fittings which have to meet stringent hygiene requirements, two seals, which are arranged at an axial distance from one another in the housing of the fitting, in conjunction with the rod surrounded by the two seals delimiting a chamber which adjoins the interior of the housing of the fitting and can be supplied with cleaning agents. Such a method and means for carrying it out ensure that, in addition to the chamber delimited by the two seals, the contact surface between the rod and the seal, the latter sealing off the interior of the housing of the fitting from the chamber, is also cleaned completely and reliably. These advantages are achieved inter alia by virtue of the fact that, when a certain excess pressure of cleaning agent in the chamber (6) relative to the interior (2) is exceeded, the first seal (7) or first sealing location (7a) sealing off the interior (2) from the chamber (6) is expanded radially and/or axially in such a way that the cleaning agent flows out of the chamber (6) into the interior (2). <IMAGE>

Title: Method and arrangement for the optoelectronic control of the weld formation in the automated longitudinal welding of pipes
Inventor: NIEDERHOFF KURT DR
IPC: B23Q35/128
Filed: 1986-02-21
Abstract: The invention relates to a method for the longitudinal welding of pipes made of steel alloys or non-ferrous metals, in which the light radiation coming from the red-hot weld deposit is measured optoelectronically for determining the weld width and for the regulation, derived from this by desired-value comparison, of the welding current, and in which the position of the welding torch(es) during the feed of the slit pipe is adapted to the position of the welding gap on the basis of measuring signals likewise recorded optoelectronically. In order to ensure uniformly high welding quality, it is proposed that both measuring signals (signal for determining the weld width and signal for determining the position of the welding gap) be recorded in a path-dependent manner by in-phase, continuous scanning transversely to the weld or the welding gap across the width of the weld or the welding gap. In this arrangement, the sensor devices for recording the signals are held in a fixed position relative to one another, the signal patterns are compared with one another in accordance with the path, and, as soon as both signal patterns do not lie concentric to one another, the position of the welding torch(es) is displaced transversely to the direction of the welding gap in such a way that the concentricity of the signal patterns is achieved again. <IMAGE>

Patent DE-3611959-A1 (DE)
Title: Synchronisation method
Inventor: SCHEIDT HELGA
IPC: H04B1/713
Filed: 1986-04-09
Abstract: In cases where exacting requirements with regard to immunity to interference are imposed on signals transmitted via radio, so-called burst mode is commonly used, often in conjunction with a frequency-hopping method. A preamble in the form of a shift-proof code word (CW) is placed in front of the error-protected information in formatted form. In order to achieve fast synchronisation of the bit and frame phase at the receiving end with the aid of the preamble, it is proposed to sample each bit (bit1, bit2...) of the incoming signal n times continuously, in each case to form the consecutive signal sample values relating to a specific bit phase (1, 2, ... 8) into signal sample sequences (sq1, sq2...sqx, sqy...sqn, sq(n+1)...sq(n+9)) corresponding in number to the number of preamble bits, to compare the order of these signal sample sequences with the preamble permanently stored at the receiving end for correspondence and to define the correct bit and frame phase depending on the results of the comparison. <IMAGE>

Title: Method for separating the impurities from contaminated metals, and apparatus for carrying out the method
Inventor: WILLE HEINZ
IPC: F23G5/027
Filed: 1986-04-17
Abstract: A method for separating the impurities from contaminated metals by heating by means of hot waste gases is described, in which the waste gases are generated by a burner. The contaminated metals are introduced into a receiving chamber capable of being closed in a leaktight manner. During a heating-up phase, the waste gases from the burner are then fed into a first circuit, from a combustion chamber provided with the burner into the receiving chamber and from there, together with the dustlike or gaseous combustible impurities separated from the metal, back to the burner and the combustible impurities are burnt in the burner. The waste gases are then diverted into a second circuit in which they are led into a heating chamber surrounding the receiving chamber. Once the separation of the combustible impurities from the metals is complete, a third circuit is opened in which the waste gases are led back to the combustion chamber through a by-pass conduit, avoiding the receiving chamber and the heating chamber. <IMAGE>
