  • Capacitive pressure sensors or capacitive differential pressure sensors
    Patent number: 6252759
    Abstract: In order to avoid short-circuits between the electrodes, the pressure sensor comprises: a substrate (11) made of ceramic material, on one surface of which an electrode (13) and a glass layer (14) formed from an original glass frit are disposed; a diaphragm (12) made of ceramic material, which is permanently joined and pressure-sealed to the substrate by means of the original glass frit acting as a spacer (17) holding the diaphragm and the substrate from each other to form a cavity (16), and which on the cavity side is provided with an electrode (15); and leads (18, 19) which extend inwards and/or through the diaphragm (12) to the electrodes (13, 15) in the region of the spacer (17). The differential pressure sensor is formed in a mirror-inverted arrangement in relation to the centre plane of the substrate, so that it carries two pressure sensors. These are pressure-linked by a hole (41) filled with oil and connecting the two cavities and leading through the substrate and outwards.

  • Process for preparing alkyl chlorides
    Patent number: 5767330
    Abstract: The preparation of long-chain alkyl chlorides from alcohols and hydrogen chloride is improved by carrying out the reaction at a temperature below the boiling point of the alkyl chloride, and distilling off the resulting alkyl chloride by feeding in additional hydrochloric acid.

  • Device for treating internal surfaces of cylindrical articles
    Patent number: 4848266
    Abstract: A device for treating internal surfaces of cylindrical objects by rubbing includes a plurality of rubbing pins each provided with two pin clamping devices one of which is displaceable relative to the other so that each pin can be adjusted relative to a workpiece.

  • Device for coating metallic internal surfaces
    Patent number: 4836130
    Abstract: A device for coating metallic internal surfaces of cylindrical objects, particularly cylindrical sliding sleeves, by rubbing materials onto said surfaces includes one or a plurality of rubbing heads each including rubbing pins positioned in said rubbing head at an angle relative to each other. Each rubbing head is displaceable along an axis thereof. A rotationally-fixed housing carries a rotatable bevel gear. The rubbing head is rotational and provided with pinions meshed with said bevel gear.
