Patent number: 7496471Abstract: Embodiments of the invention relate to a method for minimizing the influence of disturbing signals during calculation of shape elements from coordinate points. An aim of the embodiments of the invention is to exclude the coordinates which are not to be locally assigned to the desired shaped element from the calculation of the shaped element. Said aim is achieved by combining compensation methods for calculating the desired type of shaped element with recognition methods for the same type of shaped element and using the recognition methods for filtering the coordinate points that are relevant for calculating the shaped element out of all input coordinate points.Type: GrantFiled: July 16, 2007Date of Patent: February 24, 2009Assignee: Trimble Jena GmbHInventors: Christian Usbeck, Peter Brueckner, Olaf Kuehn, Gerhard Linss

Patent number: 7254262Abstract: A method for optimizing target quantities for optical precision measuring includes obtaining ancillary parameters from image data of a workpiece which is to be measured. Control data for influence quantities of the target quantities are derived from the ancillary parameters. The control data is derived as follows: by determining the courses of the ancillary parameters depending on at least one influence quantity and the courses of the ancillary parameters are determined in such a way that the courses have a like extremum of the functional dependence from the influence quantities. An overall course of the ancillary parameters is determined and an extremum of the overall course of the ancillary parameters is determined. Corresponding values of the influence quantities are determined at the site of the determined extremum as control data for the influence quantity.Type: GrantFiled: October 20, 2003Date of Patent: August 7, 2007Assignee: Carl-Zeiss-StiftungInventors: Uwe Nehse, Gerhard Linss, Olaf Kühn

Patent number: 5330342Abstract: An apparatus for manufacturing a tube-like preform having a longitudinal wall with a variable cross-section for blow molding of a hollow body from a thermoplastic material, includes a tubular die having a variable exit opening, and a collar die having a recess and movable into engagement with and away from the tubular die, the preform being produced by ejecting of the thermoplastic material from the exit opening of the tubular die into the recess of the collar die while moving tubular die, with controlling a speed of movement of the collar die and a cross-section of the exit opening of the tubular die in such a manner that larger and smaller cross-section of the exit opening correspond to speed rate of the collar die, so that a thickness of the wall of the producible preform changes from peaks to valleys in a wave-like manner to form the variable cross-section of the wall.Type: GrantFiled: November 20, 1992Date of Patent: July 19, 1994Assignee: Ossberger-Turbinenfabrik GmbH & Co.Inventors: Gerhard Linss, Karl-Friedrich Ossberger

Patent number: 4808105Abstract: An apparatus is disclosed that is intended for manufacturing a hollow body. The hollow body has a head piece formed by blow-molding a preform segment. The apparatus includes a ring-shaped nozzle, a withdrawal device, and blow-mold pieces which are laterally, reciprocally movable. Regions of the hollow body are fabricated to have outer diameters which are less than the diameter of the extruded tubular segment before the segment is blow-molded. This is achieved by a reciprocally movable mandrel with a molding extension. The molding extension extends both radially and inwardly between projecting regions of the closed blow-mold pieces. The projecting regions of the blow-mold pieces press the corresponding parts of the preform segment against the molding extension, wherewith the ring-shaped nozzle opening is radially, outwardly offset with respect to the outer contour of the molding extension.Type: GrantFiled: February 10, 1988Date of Patent: February 28, 1989Assignee: Ossberger Turbinenfabrik GmbH & Co.Inventors: Gerhard Linss, Karl-Friedrich Ossberger

Patent number: 4806091Abstract: In an apparatus for manufacturing a hollow body, the hollow body comprises an injection-molded head piece, a body part formed by blow molding a preform segment which segment is integral with the head piece. The apparatus comprises a ring-shaped nozzle wherein a ring-shaped nozzle opening is defined between a nozzle cone piece and a nozzle opening piece. The apparatus further comprises a withdrawal device operative with respect to the ring-shaped nozzle, which withdrawal device is axially, reciprocally movable and has a recess. It is desired to enable production of different and/or novel configurations of the body parts of the hollow body. This is achieved by means for an additional mold device which is provided for an additional forming operation operative on the preform segment adjoining the head piece, which operation relates to the walls of the body part. The additional mold device provides an offset in the radial sense with respect to the ring-shaped nozzle opening.Type: GrantFiled: February 10, 1988Date of Patent: February 21, 1989Assignee: Ossberger-Turbinenfabrik GmbHInventors: Gerhard Linss, Karl F.

Patent number: 4806092Abstract: In an apparatus for manufacturing a plastic hollow body which hollow body is open on one end and closed on the other, for the forming of a head piece a withdrawal device rests on a ring-shaped nozzle having a ring-shaped nozzle having a ring-shaped nozzle opening, and for the forming of a plastic tubular segment the bottom elements of blow-mold pieces rest on the ring-shaped nozzle, to provide for blow-molding of the tubular segment by blow means.It is desired to be able to produce a hollow body with a closed head piece and a perforated bottom member.Type: GrantFiled: February 10, 1988Date of Patent: February 21, 1989Assignee: Ossberger Turbinenfabrik GmbH & Co.Inventors: Gerhard Linss, Karl-Friedrich Ossberger

Patent number: 4806093Abstract: In an apparatus comprised of a ring-shaped nozzle in a nozzle piece, which ring-shaped nozzle has a reciprocally movable nozzle cone piece, wherewith the cone piece and nozzle piece together define a ring-shaped nozzle opening, it is desired to modify the ring-shaped nozzle such that, in the manufacturing of hollow bodies, the amount of scrap can be reduced and the range of practicable applications of the apparatus can be extended. This is achieved in that an additional device or arrangement is provided for closing the nozzle opening. With the improved apparatus, one can achieve improvements in the hollow body being produced, the improvements being attributable to a special technique of closing the ring-shaped nozzle, which technique is enabled by the novel closure device.Type: GrantFiled: February 10, 1988Date of Patent: February 21, 1989Assignee: Ossberger-Turbinenfabrik GmbH & Co.Inventors: Gerhard Linss, Karl F. Ossberger
