Abstract: A measuring system for measuring the relative position of two machine parts of a processing machine includes a scale fastened at one end by means of screws to the slide of the machine. The other end of the scale is joined by means of an adhesive layer with one end of an expansion element. The other end of the expansion element is fastened in a similar manner by means of screws to the slide. For the compensation of thermally induced length changes of the scale, the expansion element is provided with a coefficient of thermal expansion substantially greater than that of the slide piece. Thermal expansion of the expansion element is dimensioned in such a way that the measuring length of the scale is preserved in an unaltered length in the event of temperature fluctuations by means of increased compressive forces applied by the expansion element to the scale.

Abstract: An incremental measuring instrument having a series of reference marks extending alongside a division of a scale is provided with a selector element which is slideable along the length of the scale and can be aligned with a selected one of the reference marks in order to bring the selected reference mark into operation. The position of the selector element with respect to the selected reference mark is fixed by a plurality of filler elements which cooperate with a selector element to form a column of elements arranged end to end within a guide. Holding elements at the ends of the guides preclude undesired longitudinal movement of the column of elements.

Abstract: An arrangement for fastening a support of a scale of a linear measuring device on a mounting surface of an object to be measured. The arrangement includes a clamping jaw and a force-exerting element urging the clamping jaw against the support. The clamping jaw acts together with the support in such a way that the clamping jaw urges said support with a clamping force that includes 1) a first force component against the mounting surface by the force-exerting element and 2) a second force component that urges the support against an attachment face extending transversely to the mounting surface. The attachment face is directly constituted by an attachment body, which can be fixed positively and free of play in a receptacle on the object to be measured.

Abstract: The housing of a position measuring arrangement is fastened over length balancing elements to a first object such as a slide of a machine tool. A measurement embodiment is mounted over a highly elastic adhesive layer on an inner surface of the housing and is scanned by a scanning arrangement. In order to achieve a low-vibration fastening of the housing, it is supported in supporting zones formed between side surfaces of the housing and the exterior surface of the slide. The free length expansion between the housing and the slide is ensured by providing an elastic adhesive layer in the supporting zone.
