| Number | Title | Issue Date |
| 6622114 | Method for determining the weight of a probe of a coordinate measuring machine The invention is directed to a method for determining the weight of a probe of a coordinate measuring machine wherein the probe is connected to a probe head (1) of the machine. The machine includes a control unit and the weight of the probe (3) is prefera... | 09/16/2003 |
| 5623766 | Probe head for coordinate measuring apparatus with damping and clamping features The invention is directed to a probe head of the measuring type equipped with measuring force generators (15 to 17) for the generation of measuring forces of pregiven magnitude and direction. The probe head further includes a system for arresting or clamp... | 04/29/1997 |
| 5065525 | Length or angle measuring device At least one of the surfaces of the glass or glass-ceramic graduated-scale support (12) of a measuring device is drawn toward a corresponding surface of the guide part (11) by the capillary action of a liquid film (13). The graduated-scale support floats ... | 11/19/1991 |
| 4937948 | Probe head for a coordinate-measuring instrument A probe head for coordinate-measuring instruments has a torsionally rigid, play-free and friction-free probe-suspension system which defines a three-dimensional coordinate system, wherein a probe pin is deflectable in all three directions in space. In ord... | 07/03/1990 |
| 4882848 | Probe head for a coordinate-measuring instrument A probe head for a coordinate-measuring instrument has a torsionally rigid, play-free and friction-free probe-suspension system which defines a three-dimensional coordinate system wherein the work-contact pin of the probe is deflectable in all three direc... | 11/28/1989 |
| 4523382 | Work-contact probe head for coordinate-measuring instruments The invention contemplates a so-called switching probe head in which the movable element of the probe has a tensed at-rest position on support structure which determines its zero position and from which it is displaced upon work contact. To increase the a... | 06/18/1985 |
| 4520700 | Tailstock for rotatably mounting a workpiece in precision machinery A tailstock for rotatably supporting a workpiece on a machine bed. The tailstock includes a vertical column fixed at the machine bed which has first and second regions. The second region of the column is coaxial with the first region and pivotally mounted... | 06/04/1985 |
| 4515415 | Plain bearing The invention contemplates a plain bearing which is guided on a prismatic rail (9) and in which the bearing elements are rollers (25 to 28) having longitudinal axes oriented parallel to the guidance direction. These rollers (25 to 28) are resiliently reta... | 05/07/1985 |
| 4509871 | Play-free anti-friction bearing construction The invention contemplates an anti-friction bearing wherein the inner raceway for a complement of rolling elements is ground directly in the shaft which is to have anti-friction support. The outer raceway is provided in the bore of a relatively thin-wall ... | 04/09/1985 |
| 4497522 | Guide means for rolling elements of a ball-race device A ball-race shoe contains plural adjacent endless rows of rotating balls. Balls of adjacent rows are in mutual contact and are staggered with respect to each other to a longitudinal extent equal to the radius of a ball. The arrangement packs the balls as ... | 02/05/1985 |
| 4177568 | Measurement head The invention contemplates an improved work-contacting probe for use in a measuring machine wherein the relationship between contacted locations on a workpiece are reduced to coordinate digital data. The various described probe embodiments feature means w... | 12/11/1979 |
