Abstract: A sensor includes a mount arranged along a sensor axis, an airfoil body fixed to the mount and having a first face and second face extending along the sensor axis, a heater element, and a temperature probe. The heater element and the temperature probe are positioned within the airfoil body and extend axially along the airfoil body. The airfoil body defines within its interior a pressure channel having an inlet segment extending between the heater element and the first face of the airfoil body to prevent ice formation and/or melt ice entrained within air traversing the pressure channel. Gas turbine engines, methods of removing ice or preventing ice formation, and methods of making sensors are also described.

Abstract: The invention relates to a mounting press for automatically mounting metallographic samples in mounting material, comprising: a pressing unit with the press cylinder, a feeding device for feeding mounting material, e.g.

Abstract: The present disclosure relates to a laboratory wheel grinder and a method for plane grinding a lower side of specimens, in particular mounted specimens, as well as a replacement grinding disc for the laboratory wheel grinder and the use of a grinding disc in a laboratory wheel grinder, wherein the grinding disc is divided into a peripheral annular first surface and a central second surface arranged within the peripheral annular first surface wherein the upper surface of the carrier disc is covered with the abrasive only in the peripheral annular first surface so as to form a grinding peripheral annular first surface and a passive central second surface.

Abstract: A hardness testing device has at least one penetrator (9), arranged on a holder (15), for producing an impression (27) in an object under test (3) and at least one lens (12) for detecting at least one measure of the impression (27) in the object under test (3), which can be positioned alternately over the object under test (3). The holder (15) is mounted on the hardness testing device (6) in such a way as to be able to rotate around its longitudinal axis.

Abstract: The modular conveyor system comprises N interconnected track sections, forming a continuous track, wherein each track section features a plurality of individually controlled coils stretching along the length thereof. Plural pallets, each having thrust producing magnets, travel independently alone the track. The track also comprises multiple linear encoder readers spaced at fixed positions therealong, and each pallet includes a linear encoder strip having a length R greater than the spacing E between the readers. Track section controllers associate the encoder strips with only one reader at any time in order to resolve the position of the pallets based on the fixed position of the readers and the relative positions of the strips in relation thereto. The section controllers also regulate and commutate the coils of the corresponding track sections in order to independently control each pallet. Communication links interface adjacent section controllers situated in adjacent track sections.
