Abstract: A sintered molded article includes a ceramic of ?/?-sialon having a grain boundary phase, the grain boundary phase containing at least one hard material formed in situ as an additional phase. A method for the production of the sintered molded article uses at least the following compounds as a starting material: Si3N4, AlN, and, if applicable, Al2O3, at least one oxide of the rare earths, and at least one oxide of the element titanium.

Abstract: A cross-type limit switch (10) with a housing (12) that contains a gear mechanism (24) that includes a cover plate (38), base plate (48), and intermediate plate (42). The intermediate plate (42) has first and second cutouts (44, 46) within which respective gearwheels (54, 58) are arranged. The first and second gear wheels (54, 58) have respective plugthrough openings (56, 60), and a shaft (20) coupled to an actuating lever (18) outside the housing is rotatably mounted in a first bearing arrangement (22) connected to the housing. The actuating lever shaft (20) extends through the first plugthrough opening (56) of the first gear wheel (54) for rotating and radially locating the first gear wheel (54). A rotary switch (30) arranged in the housing (12) has a switch shaft (138) rotatably mounted in a second bearing arrangement (106, 34) that extend through the second plugthrough opening (60) of the second gearwheel for rotating and radially locating the second gearwheel (58).

Abstract: The invention relates to ?/?-sialon-based materials. The invention particularly relates to ?/?-sialon-based materials that have an improved sintering activity and impart high edge strength to the sintered molded articles made of said materials.

Abstract: A highly refractive and highly transparent optical glass is provided. The use of such a glass, optical elements and processes for producing the glass or the optical elements are also provided.

Abstract: A sensor device has a structural element, a carrier element and a housing, the structural element being situated on the carrier element, and the structural element and the carrier element being situated at least partially within the housing. The sensor device also has an intermediate housing, which is situated essentially between the housing and the structural element, the intermediate housing including a premold housing.

Abstract: A chain sprocket for link chains, for example, round link chains or profiled steel chains, has chain pockets for horizontal chain links. Chain pockets for vertical chain links are also provided. The chain pockets for the vertical chain links are separated from one another by teeth. The tooth flank surface of the tooth that a vertical chain link contacts under the effect of a load is dimensioned and profiled in a special manner. The dimensioning is such that up to a defined chain load the vertical chain link does not contact the tooth flank with its nose. A contact between the tooth flank surface and the nose of the respective chain link occurs only above a defined chain load.

Abstract: A surge voltage protector having a tubular ceramic part as an insulator, and having metal electrodes soldered onto the end faces thereof. Each electrode is electrically connected in each case to an ignition aid applied at least to the inside wall of the ceramic part. The inside edges of the surfaces joining the ceramic part to the electrodes are each provided with a chamfer whose chamfer angle is 15.degree. to 60.degree. relative to the plane of the joining surfaces. The width projected onto the plane of the joining surface is 0.05 to 0.4 mm.

Abstract: In the pump piston for axial piston pumps which comprises a ceramic piston and a drive member of metallic material the ceramic piston has an end face of which from 20 to 80% is in the form of a joint surface for a soldered connection to the drive member.
