Abstract: The invention relates to a piece of furniture comprising an integrated massage unit. A supporting surface is disposed on said piece of furniture between a body that leans thereagainst and the massage unit. The massage unit comprises at least one massage body. In order to improve the massaging effect and make the massage feel neither too vigorous nor too weak in the user's subjective perception in any adjusted position of the massage unit regardless of the force that is exercised by leaning thereagainst, a support element (10) backing the body relative to the massage body (5) is disposed on the side of the supporting surface (3), which lies opposite the body, in the area of the massage body (5). Said support element (10) is adjustable in such a way that a vertical movement component allowing depth adjustment is created, the vertical movement being in relation to the supporting surface (3).

Abstract: In a method of making a ceramic shaped body which permits an adjustable volume change (shrinkage, zero shrinkage or increase in volume) compared to its green product, a metal oxide powder and a metal powder are stirred in a colloidal sol into slip and that slip is then consolidated in a mold into a green product by freeze-gelling and finally the green product is sintered in an active atmosphere which enables the metal powder to oxidize, to form the shaped body. The disclosure is also concerned with a slip for a shaped body of this kind and advantageous uses for the shaped body.

The longitudinal groove can provide two or more laterally separated running surfaces for the at least one ball. An area with a larger radial distance can be provided on at least one rod element between adjacent running tracks for an assigned ball, this being able to act as an abutment for the ball in the manner of an overload protector.

Abstract: A method and apparatus for ascertaining internal stresses in a hardened region to be tested for a component made of a predetermined material includes measuring coercive field strength and amplitude of magnetic Barkhausen noise as a function of mechanical stress and hardness in calibration samples of a predetermined material of known hardness and known internal stress. Calibration functions are ascertained from the measured values indicating the dependency of the hardness and the amplitude of the magnetic Barkhausen noise as functions of the hardness and mechanical stress. The coercive field strength and the amplitude of the magnetic Barkhausen noise is measured in a location-dependent manner over the region of the component to be tested. The measured values of the coercive field strength and the amplitude of the magnetic Barkhausen noise are converted in the region to be tested into location-dependent hardness and into location-dependent mechanical stress using the ascertained calibration functions.
