Abstract: A method for measuring flatness of a factory floor upon which machinery is to be mounted using a rotating laser beam that emits a rotating laser beam in an essentially horizontally plane. A photosensitive position sensor delivers an electrical pulse, which is identified by its timing and phase angle, during illumination by the laser beam. The phase angle and timing of these pulses constitute a measure of the position of the sensor in the coordinate system. Measurements are taken with the sensor positioned at each location at which the machinery is to be fixed to a factory floor. The method determines any differences in height between the measurement points and the amount, if any, that the floor needs to be adjusted at each mounting point to insure that a machine that is affixed to the floor these points will be level.

Abstract: A position measuring device with a rotating laser beam includes a laser transmitter that is positioned in a polar coordinate system and emits at least one rotary laser beam in an essentially horizontally lying plane. A photosensitive position sensor delivers an electrical pulse, which is identified by length in time and phase angle, during illumination by the rotating laser beam. The phase angle and length in time of these pulses constitute a measure of the angular position and the radial distance of the sensor in the indicated polar coordinate system. Measurements are taken with the sensor generally positioned at predefined locations. The device determines the difference between the actual measurement point and the predefined target measurement point and adjusts the measurement data accordingly. The adjusted data is used to determine the flatness of a surface.

Abstract: A position measuring device with a laser beam which rotates with a given constant rotary speed, a laser transmitter which is centered in a polar coordinate system present and emitting at least one rotary laser beam into an essentially horizontally lying plane, and allowing delivery of a synchronous signal with respect to a reference angle. A photosensitive position sensor is provided which delivers an electrical pulse which is identified by length in time and phase angle during illumination by the rotating laser beam, and the phase angle and length in time of these pulses constitute a measure of the angular position and the radial distance of the sensor in the indicated polar coordinate system.

Abstract: A device for rotating an emitter device emitting a laser beam L about a rotation axis for the purpose of generating a plane or a conical surface has an elongated body of revolution 2 which carries the emitter device 1 and is held rotatably at the ends on a fixed holder 5 by means of a pivot bearing 3, 4 in each case, the pivot bearing 3, 4 comprising a conical seat 16 and a bearing member 17 engaging in the latter and having a rounded outer surface concentric with the rotation axis, and the conical seat 16 and the bearing member 17 being prestressed (20) against one another.

Abstract: The spatial position of rollers or other mutually adjacent articles is measured or examined by indirect transport of a reference direction. To this end, an adaptor is placed on one of the rollers. The adaptor is equipped with a light source which emits a light beam substantially parallel to the axis of rotation of a roller. The light beam is sensed by a movable sensor unit. The latter determines, at the same time, the angle of incidence of the light beam according to two axes, relative to the sensor unit, and the orientation of the sensor unit relative to a reference axis system (laboratory system). A multi-axially operating gyroscope is used for the last-mentioned measurement. A suitably programmed electronic system or computer determines, from the two measured values, the orientation of the adaptor and of the roller with respect to azimuth and elevation in the laboratory system.

Abstract: A device for connecting a coaxial cable to first and second contacts which are secured in an enclosure. The enclosure is equipped with an insert having an inner bore to snugly seat the coaxial cable and whose center axis is in true alignment with the first contact. The second contact includes a contact spring device circumferentially clamped in the enclosure in an essentially rigid manner and having tabs with sharp free ends extending toward a contact pin rigidly fastened in the enclosure. The tabs are bent outward at identical angles from a plane defined by the clamped position of the contact spring device toward the inner bore of the insert. The insert is equipped with a rigid thrust face for exertion of pressure against the tabs of the contact spring device. The contact spring device, the contact pin and the insert are matched to one another and located in the enclosure.
