  • PRESSURE SENSOR WITH IMPROVED DIAPHRAGM SEAL
    Publication number: 20240068898
    Abstract: A method for manufacturing a sensor. The sensor includes a sensing element and a housing, the housing including an interior space, which is accessible through a housing opening, and the sensing element being situated in the interior space and being designed to detect a property and/or a composition of an ambient medium of the sensor. The method includes filling the interior space with a protective medium through the housing opening, the protective medium being designed to transfer the property and/or the composition of the ambient medium to the sensing element; fixing a preferably flexible diaphragm at or in the housing opening preferably for sealing the housing opening, the diaphragm including at least one diaphragm opening; and sealing the at least one diaphragm opening. A sensor, which is manufactured according to this method, is also described.

  • Process for the preparation of aminoaryl- and aminoheteroaryl boronic acids and esters
    Patent number: 9738663
    Abstract: The present invention relates to a process for the preparation of aminoaryl- and aminoheteroaryl boronic acids and esters thereof of formula (I) in high yield. The claimed process uses diarylketal formula (V) to generate an arylbromide of formula (III) in which the amino-group is protected as bisarylmethylidenimino-group, which is then transformed into a formula (I) compound.
