Patent DE-19913904-C1 (DE)
Title: Process for sealing ducts on connecting elements of a base body against liquids and gases, for soldered components, includes a sealing compound
Inventor: LEHNER BARBARA
IPC: H05K3/34
Filed: 1999-03-26
Granted: 2001-02-01
Abstract: The connecting elements are coated with a solder (5) and protrude through a sealing compound (7). By initiating a first partial hardening, the base body adheres to the connecting elements and seals the ducts. A second hardening reaction is initiated causing shrinkage of the sealing compound which fills the gaps exposed by the solder melting away.  Process for sealing ducts of connecting elements (4) of a base body (2) against liquids and gases. The connecting elements are coated with a solder (5) and protrude through a sealing compound (7). The compound is applied to the base body with inclusion of the connecting elements. By initiating a first partial hardening of the compound with a first partial reaction, at a temperature T1 over a period t1, the base body adheres to the connecting elements and seals the ducts. By soldering the connecting elements at a temperature T2 over a period t2, a second hardening reaction of the compound is initiated with a second partial reaction. Through shrinkage of the sealing compound caused by the second partial reaction, the gaps exposed by the solder melting away are filled between the connecting elements and the base body, and sealed.

Title: Speed measuring system calibration
Inventor: JOPPE TOBIAS
IPC: G01P3/66
Filed: 1999-05-31
Granted: 2001-03-22
Abstract: The method involves calibrating a speed measuring system, with which the speed of a passing carriage is determined by means of two, sequentially measuring contacts under consideration of a predetermined contact distance value. A wheelbase of passing carriages is determined from a measurement under consideration of the measured speed, and it is adaptively determined, whether the carriages belong to predetermined carriage groups with predetermined lower and upper nominal wheelbases.  A corrected contact distance value corresponding to an actual contact distance, is formed from the determined wheelbases of the passing carriages, and the corrected contact distance value is used instead of the initial contact distance value for subsequent measurements.

Title: Fine air feed to natural gas by peristaltic micro-pump prevents irreversible change to odor measuring cells
IPC: G01N33/28
Filed: 1999-06-10
Granted: 2000-12-14
Abstract: A gas detector and analysis unit measures the concentration of odors deliberately introduced into natural gas, using electrochemical cells. Due to the absence of atmospheric oxygen in the natural gas the cells function for only a limited time, following which they undergo an irreversible change in their characteristics. The pump introduces a one percent admixture of air to the natural gas. A flow of natural gas of 6-10 litres/hr receives preferably 60-100 ml air per hour. Following the measurement of odorous substances, the mixture or air and gas is preferably discharged to the atmosphere. In order to minimize the possible effect of cross-sensitivity, the gas is measured both before and after the introduction of the odors.
