Patent number: 5507099Abstract: An arrangement for measuring distortion in cylinders. A sensor projects straight out of the end of a motion-transmitting arm. The arm can be both translated and rotated. The sensor accommodates a probe that probes the geometry of the surface of the cylinder. The sensor has a distortion-measuring structure accommodated in the head of a surface-geometry probe and a check for axially secured and undeflected tensioning of the probe. The probe is an elongated geometry-probing pin. The structure is securely tensioned remote from the chuck in the vicinity of a structure-attachment section in the head. The structure includes at least one zone of attenuation between the chuck and the structure-attachment section and has a resilient section and a strain gauge.Type: GrantFiled: March 17, 1994Date of Patent: April 16, 1996Assignee: Pietzsch Automatisierungstechnik GmbHInventors: Knud Overlach, Manfred Wamser

Patent number: 5095634Abstract: A probe is an elongated tube with sensors positioned to match the cylinder bores with respect to number and distance apart and having radially projecting contact pins. When employed as intended, the probe rotates and slides back and forth in stationary bearings that are in turn accommodated in uprights in a stand. The probe extends through the bores of the work, which is precisely positioned between the uprights by the same bearings. A drive unit with a driveshaft in alignment with the probe and with motors that operate in conjunction with the latter to generate a translation and a rotation respectively is also mounted stationary in the stand independent of the aforesaid bearings. One end of the probe is coupled to the driveshaft such that it can neither rotate on nor slide axially along it by a universal joint that compensates within limits for angular error and radial shaft displacement.Type: GrantFiled: July 25, 1990Date of Patent: March 17, 1992Assignee: Pietzsch Automatisierungstechnik GmbHInventors: Knud Overlach, Manfred Wamser

A sensing section along the roadway with one end a maximum length from the sill corresponding to the smallest spacing between axles to be measured and another end a minimum length from the sill corresponding to the largest spacing between axles to be measured. A first wheel on a first axle of the vehicle being located at the sensing sill and a second wheel on a second axle on the vehicle being located on the sensing section when measuring the distance between the two axles by using the distance measured between the second wheel and the sensing sill.Type: GrantFiled: February 12, 1990Date of Patent: June 4, 1991Assignee: Pietzsch AGInventors: Harald Kauer, Knud Overlach, Rolf Edelmann, Siegfried Gassner

Patent number: 4986004Abstract: For the purposes of measuring the configuration of cylinder bores, at least one measuring probe with a plurality of measuring sensors each having respective radially projecting sensing pins is introduced into the cylinder bore, without the sensing pins touching the cylinder bore, and the sensing pins are then brought into contact with the cylinder wall by relative displacement of the workpiece and the measuring probe with respect to each other. Thereupon the measuring head is fixed with respect to the workpiece and that fixing is maintained by means of a biasing force, whereupon, with the workpiece resiliently seated and with the measuring head decoupled from members which produced the advance movement thereof, the configuration of the cylinder bores is measured by sensing by means of the sensing pins on adjacent parallel circles.Type: GrantFiled: January 3, 1990Date of Patent: January 22, 1991Assignee: PAT Messtechnik GmbHInventors: Rudolf Hartmann, Knud Overlach, Gunter Suchanek

Patent number: 4692943Abstract: In a method of opto-electronic inspection of a two-dimensional pattern on an object, especially a printed board, a micro-inspection is carried out by subjecting line-by-line scanned picture elements in pixel-by-pixel fashion to a sequence of picture operations for inspection of dimensions and spacings, and the respective result is compared with the corresponding scanned pixel. At the same time a macro-inspection is carried out by combining the scanned pixels to frames and by respective reduction thereof to a single characteristic picture information, whereupon a comparison is again performed, but this time with the corresponding picture information of a reference picture. In this way it is possible to perform a quick and fully automatic real-time inspection of two-dimensional patterns, for instance printed boards, both for minute and hardly visible defects and for macro-defects.Type: GrantFiled: December 27, 1984Date of Patent: September 8, 1987Assignee: Dr. Ludwig Pietzsch GmbHInventors: Ludwig Pietzsch, Knud Overlach, Detlef Senger, Walter Breunig

Patent number: 4616723Abstract: A wheel load indicator comprises a rectangular flat plate (1) of a light material having measuring properties. A series of recesses (4) forming webs (5) are provided along two lateral edges (6) of the plate (1). Strain gauges (12) are adhesively bonded to walls of bores (10) in the area of the webs (5) to determine the shearing stress under the load of a wheel (100) which has driven on the bending portion (3).Type: GrantFiled: June 19, 1985Date of Patent: October 14, 1986Assignee: Ing Ludwig Pietzsch GmbH & Co.Inventors: Ludwig Pietzsch, Knud Overlach, Siegfried Gassner

Patent number: 4393698Abstract: A measuring device for hollow cylindrical surfaces, such as bores and the like, comprises a housing to be fixed in the bore by clamps, a measuring arm rotatable by a first step motor, a measuring head axially movable along the measuring arm substantially parallel to the axis of the bore surface by a second step motor and a sensor incorporated in the measuring head and radially movable relative to the measuring head against the force of a leaf spring in contact with the bore surface. The leaf spring supports strain gauges, the output signals of which are representative of the radial or transverse paths of the sensor and thereby for the shape of the bore surface to be measured.Type: GrantFiled: June 22, 1981Date of Patent: July 19, 1983Assignee: Ludwig PietzschInventors: Ludwig Pietzsch, Knud Overlach, Manfred Wamser

Patent number: 4077340Abstract: A workpiece prepuncturing device for use with a sewing machine having drive means for reciprocating a needle and means for feeding a workpiece into association with the needle to sew a stitch comprises a perforating tool which is located at a spaced location from the needle which is comparable to a multiple of the stitch length. The perforating tool cooperates with a counter tool which is mounted on the opposite side of the workpiece and is movable toward and away from the workpiece in timed relationship to the speed of the feed and the reciprocation of the perforating tool. The counter tool is supported in a base portion of the sewing machine by an elastic suspension, and it is in drive connection with the main shaft of the machine which operates the needle and the feed for the workpiece.Type: GrantFiled: October 4, 1976Date of Patent: March 7, 1978Assignee: Pfaff Industriemaschinen G.m.b.H.Inventors: Oskar Braun, Reinhold Dobner, Knud Overlach, Ludwig Pietzsch
