Title: Method for observing the progress in time of an object program
Inventor: DANUSER ANDREAS
IPC: G06F15/16
Filed: 1989-11-06
Granted: 2000-05-23
Abstract: The method is used for observing the progress in time of an object program executed by a computer system. In this connection, information items relating to the flow of the object program are detected by an observation tool at an interface of the computer system, and are evaluated. This method is intended to provide the possibility of observing even complex computer systems almost under real-time conditions with comparatively simple means. This is achieved by unambiguously identifiable observation points in the form of output commands which are inserted at unambiguously located points in the source program allocated to the object program. The observation points are stored in table form in a database of the observation tool, specifying the program points. When the program is running, identifications allocated to the observation points are sent to the observation tool by the computer system. The observation tool forms events, specifying the current time and identifying the transmitting object computer of the computer system. The events formed are evaluated in the observation tool in the language of the source program with reference to the observation points stored in table form.

Title: Process of and apparatus for preparing dinitrogen pentoxide
Inventor: BAGG GREVILLE EUAN GORDON
IPC: C01B21/20
Filed: 1991-07-25
Granted: 2002-04-23
Abstract: Process for producing dinitrogen pentoxide (N2O5) consists of reacting a solution of dinitrogen tetroxide (N2O4) in a volatile organic solvent, with a stream of an ozone-containing carrier gas.  N2O5 produced by reaction between the N2O4 and ozone is transferred into the gas stream, and is thereafter condensed out of the gas stream by contact with further inert or-ganic solvent. The latent heat of formation of N2O5 is absorbed by the heat of vaporisation of the solvent, so limiting in-creases in reaction temperature and suppressing the dissociation of the N2O5.  In a preferred embodiment the reaction and absorption steps are performed in separate columns having organic solvent recirculating continuously through each with carrier gas flowing continuously from the reaction column to the absorption column.

Title: Apparatus for the cleaning of exhaust gases
Inventor: KURR KLAUS
IPC: B01D46/18
Filed: 1992-12-07
Granted: 1998-10-27
Abstract: Apparatus for cleaning exhaust gas from a combustion installation includes a soot filter which is positioned in the exhaust gas flow. The soot filter has a flexible filter band which in a first zone is subjected to a through flow of the exhaust gas and can be continuously or intermittently advanced and renewed from a storage roll by a drive.  The filter band is supported in the first zone on and movable by a flexible, gas permeable continuous transport band which provides the necessary longitudinal tension.  The filter band and the particles separated from the exhaust gas are burnt together in a second zone. Thus, both the filter band and the particles on it are disposed of in the apparatus itself thereby providing an economical filtering process.  The filter band need not be strong enough itself to withstand the exhaust gas pressures which are resisted by the transport band.

Title: System for forming end flanges on pipes
Inventor: PETERSEN HORST UDO
IPC: B21D17/02
Filed: 1992-12-24
Granted: 1997-06-03
Abstract: The system increases the diameter to which pipe flanges can be flared. The tendency of the radial wall of the flange to crumple inwards is obviated by coining the transition corner of the wall. First, the pipe end is belled out to provide access for the coining punch. The belled-out end is then swaged back in, after the punch is removed. with the corner transition thus pre-conditioned, further axial pressure on the pipe with a suitable female punch causes the flange to expand diametrally in a controllable manner.
