Patent DE-19709336-A1 (DE)
Title: Method for concreting a reinforced decking, such as specialist arch sections used in tunnelling
Inventor: ZWICK OTTO
IPC: E21D11/10
Filed: 1997-03-07
Abstract: A bottom side of the formwork is spatially separated if required from a top side by spacers and is covered with the reinforcing material. This covered formwork is brought into such a position with the top side that it forms a complete, internally-reinforced formwork, or a part of the formwork to which side parts are connected. The enclosed space is then filled with a hardening material such as concrete. The reinforcing is bent at a distance from the bottom side, and the trellis work is connectively supported on the bottom side.

Patent DE-19737276-A1 (DE)
Title: Ultrasonic monitoring of duroplastic hardening for control purposes
Inventor: DOERING JOACHIM DR
IPC: G01N29/024
Filed: 1997-08-27
Abstract: Ultrasonic monitoring of duroplastic hardening for control purposes measures instantaneous hardness even when filters scatter signals strongly. A reference signal is defined, for comparison with the measured signal, by computing convolution integrals of both transducers, or by computing signal waveform in accordance with a conventional transducer model. Alternatively the signal waveform is measured in an acoustic delay line, using the same transducers. The reference signal is stored in the computer. Reference and measured signals are cross-correlated. Amplitude and delay correlation peaks are converted into a characteristic line. On the abscissa, the setting time is plotted. Independent claims are included for direct control of tools processing the duroplastic molding using the signals obtained; also for the measurement apparatus itself. The latter is summarized as the pulse generator (2), computer (1) mold (7) ultrasonic transducers (4, 6), voltage controlled amplifier (9), ADC (11) and control loop optimizing ADC resolution (8-12).

Patent DE-19803828-A1 (DE)
Title: Testing an exhaust gas catalytic converter in an internal combustion engine, for its ability to convert contaminants
Inventor: ESTEGHLAL GHOLAMABAS
IPC: F02D41/14
Filed: 1998-01-31
Abstract: The oxygen content of the exhaust gas downstream of the catalytic converter (9) is found using sensor (10). The average oxygen content of the exhaust gas is changed upstream of the converter which leads away from the previously found oxygen content downstream of the converter. Then the change in the oxygen fill level of the converter resulting from the change in average oxygen content, is found and compared with a set limit value which represents  a converter which just meets conversion requirements.  The malfunction is not indicated if the set limit value is exceeded before the oxygen in the exhaust gas downstream of the converter at sensor (10) changes. If the oxygen content of the exhaust gas downstream of the converter changes before the set limit value is achieved, the oxygen content of the exhaust gas upstream of the converter is changed in the opposite direction. The change in oxygen fill level of the converter is found from the deviation (DL) in the oxygen  content in the exhaust gas upstream of the catalytic converter for the value, which is applicable for stoichiometric ratios, and from the air quantity mL, which is drawn in by the engine. The product of the deviation (DL) at time t and or the air quantity mL which is drawn in by the engine at a time t - tT prior to time t, is integrated over time.  The time difference tT = t - (t -tT) corresponds to the gas running time between the site, at which the intake air quantity mL is detected upstream of the engine and the site, at which the oxygen content of the exhaust gas upstream of the catalytic converter is found. An Independent claim is included for a testing device for an exhaust gas catalytic converter in an internal combustion engine.

Title: Event handling method for management network
Inventor: HIRSCH LUCIAN DIPL ING
IPC: H04L12/24
Filed: 1998-02-11
Abstract: The method involves preparing a file with information stored in an event storage unit (log) by an agent (AG) when the event storage unit reaches a predetermined level (mSLS).

Patent DE-19849035-A1 (DE)
Title: Construction machinery motor noise silencer
Inventor: NAKADA KUNIAKI
IPC: G10K11/16
Filed: 1998-10-23
Abstract: The air inlets (4,5) to the silencer oppose one another in the motor space (1) wall and in two different directions. A plate-type silencer (12) facing the inlets (4) in one direction has an elongated air channel as compared with the cell-type silencer which faces the other inlets (5) and has a relatively shorter air channel. The blades (13) of both types of silencer are integral with inflexible absorption material (20). In a variant, the blades are bonded to both sides of the absorption core material for sound absorption or air permeability. The material can otherwise be plated in air-permeable material. The cell silencer blades are less wide than the blade of the plate silencer. Air is input from a fan via inlets at right angles and then via a channel so as to feed air from both inlets to a plate-mounted cooler. A shutoff plate in the channel splits this into separate channels for the two inlets (4,5).
