Abstract: A bearing ring, in particular of a rolling bearing or a sliding bearing, including a body made of a magnetostrictive material, having a first raceway (2) and a second, axially spaced apart, raceway (2?) and a permanent magnetization (3) which is impressed into the material of the body between the raceways (2, 2?) and which runs around an axis of rotation (9) of the body. According to the invention, the bearing ring achieves the object of improving the structural integration of a torque sensor into a bearing, which torque sensor generates a torque-dependent magnetic field by utilizing the inverse magnetostrictive effect.

Abstract: A segment rolling bearing for an axial hydraulic pump, which can be integrated in a simple way. The segment rolling bearing has an outer raceway carrier, an inner raceway carrier, a plurality of rolling bodies, and a cage. The rolling bodies are arranged in the cage such that they roll between the outer raceway carrier and the inner raceway carrier in such a way that the outer raceway carrier can be pivoted about a common pivot axis with respect to the inner raceway carrier. The cage is connected to the inner and/or to the outer raceway carrier directly and captively in at least one connecting region, at least in the radial direction with respect to the common pivot axis.

Abstract: Nondestructive methods and apparatus for determining a concentration of interstitial oxygen in a generally cylindrical body of crystalline silicon. The invention transmits an infrared (IR) beam through the body generally transverse to a longitudinal axis of the body and measures the absorption coefficient of an interstitial oxygen absorption band at a wavenumber W.sub.p of approximately 1720 cm.sup.-1. Further, the invention determines the concentration of interstitial oxygen in the body as a function of the measured absorption coefficient.
