Patent DE-4115369-A1 (DE)
Title: Minimising nitrogen oxide cpds. emission from engine or furnace - using agent subjected to chemical and/or physical pretreatment, avoiding need for catalyst
Inventor: OLDANI MARKUS DR
IPC: B01D53/56
Filed: 1991-05-10
Abstract: Minimising NOx in the combustion of a fuel in an i.c. engine and/or furnace uses substance(s) (I) subjected to chemical and/or physical pretreatment so that they cause a chemical and/or physical reaction with NOx. Pref. (I) reacts with NOx in any spot in the engine or furnace or in the exhaust gas stream. (I) pref. is injected into the exhaust gas, so that intensive mixing occurs, or injected into the engine or furnace. Pref. (I) is an amine, which is passed through a catalyst so that an active species forms; or (I) is subjected to catalyst treatment, before or after chemical and physical treatment. USE/ADVANTAGE - The process is very economical, since the gas is not treated with catalyst and the efficiency is not affected by different operating states of the plant, e.g. can operate at exhaust gas temps. between O and 1000 deg. C. Only relatively small amts. of (I) are needed, hence the equipment can be very small and cheap

Patent DE-4207632-A1 (DE)
Inventor: STURM VOLKER PROF DR MED
IPC: A61B90/10
Filed: 1992-03-11
Abstract: A part of the body is positioned for therapeutic treatment in that a treatment point exactly defined in relation to marks placed thereon is kept in a desired position. For this purpose, at least two video signal-generating sensors (34, 36) are oriented for observation of the marks (22, 24, 26, 28, 30). There are image-processing means (74, 76) for processing of the images (54A to 62A; 54B to 62B) of the marks in order to fix marking points (80) determined by the marks and defining the actual position of the part of the body. Furthermore, there are signal processing and regulating means (86, 88, 90; 92, 94) for calculation of the actual position from the observed position of the marking points, for comparing the actual position with a desired position and for generating adjustment signals depending on the difference between actual position and desired position. Adjustment means (102, 104, 106) are acted upon by the adjustment signals and designed to work on the part of the body. As a result, the treatment point can be brought back into the desired position on deviation from the desired position.
Patent DE-4219871-A1 (DE)
Inventor: SPAETH WERNER F
IPC: F16B7/04
Filed: 1992-06-17
Abstract: The invention concerns a connection element designed to connect two structural components, in particular a support girder and a frame girder, so that they can be detached again. The connection element is designed to be inserted in the hollow-section frame girder so that it remains fixed in place. It has at least one movable securing element which is disposed in a housing and which can be displaced in the direction of the longitudinal axis of the connection element by means of an eccentric pin which is rotatably mounted in an aperture in the housing and which passes through the securing element, thus bringing a coupling hook forming part of the securing element and projecting out of the end of the housing into engagement with a longitudinal groove undercut in the support girder. The eccentric pin is designed to be pushed into the housing against the force of a spring and locked in a cross-bore in the frame girder. In order to ensure that the securing element operates faultlessly in any position, the invention calls for the floor of the housing to have a recess which is disposed eccentrically with respect to the mounting aperture and with which a cam disc on the eccentric pin is brought into engagement at least when the securing element is in its extended position.
