Patent number: 7236310Abstract: A device for adjusting the back foci of an objective and a camera to one another has a housing by which a graphic pattern and an optics are mounted at a predetermined distance F? from each other. The temperature compensation for the distance F? is constant to ±2 mm for a temperature change of Delta 20° Celsius. The device also includes an apparatus for matching the back foci of an objective and a camera to each other, in which a housing has a fastening mechanism for fastening an object-side end of the objective and a graphic pattern is arranged in the housing on the end of the device opposite the fastening mechanism. The invention also includes a method for equalizing the back foci of an objective and camera using specific steps.Type: GrantFiled: April 1, 2003Date of Patent: June 26, 2007Assignee: Carl Zeiss AGInventors: Uwe Weber, Gebhard Müller

Publication number: 20040051965Abstract: A device for adjusting the back foci of an objective and a camera to one another has a housing by which a graphic pattern and an optics are mounted at a predetermined distance F′ from each other. The temperature compensation for the distance F′ is constant to ±2 mm for a temperature change of Delta 20° Celsius. The device also includes an apparatus for matching the back foci of an objective and a camera to each other, in which a housing has a fastening mechanism for fastening an object-side end of the objective and a graphic pattern is arranged in the housing on the end of the device opposite the fastening mechanism. The invention also includes a method for equalizing the back foci of an objective and camera using specific steps.Type: ApplicationFiled: April 1, 2003Publication date: March 18, 2004Inventors: Uwe Weber, Gebhard Muller

Patent number: 6374712Abstract: A side milling cutter with cutting inserts, by which side milling cutter a crank pin can be cut with a single feed motion. The plate-shaped cutting inserts are arranged on the periphery of the side milling cutter alternating between the left and right side in a peripheral direction, and are oriented essentially radially with their cover surfaces in relation to the cutter axis, which cover surfaces contain the tool faces. The cutting inserts are also arranged so as to form a gap on the periphery of the cutter which is so narrow that the length of the arc of action between the point of entry and the point of exit of cutting is greater than the half of the gap of the arrangement of cutting inserts on the periphery of the cutter. The present invention also relates to the configuration of the cutting inserts as indexable inserts which can be used on the left and on the right.Type: GrantFiled: March 8, 2000Date of Patent: April 23, 2002Assignee: Kennametal PC Inc.Inventors: Gebhard Müller, Horst Jäger

Patent number: 6231276Abstract: In addition to having a stop member in the form of a hollow cylinder which is slotted and can be spread by means of an adjustment screw, an adjustable stop for a cutter adjustably arranged in a main casting or body of a tool is also provided with a sleeve member which can be inserted into a longitudinal bore of the stop member. The sleeve member has inside threads which can be brought into engagement with the adjustment screw. This results in an improvement of the load carrying capacity of the threaded connection. Since the sleeve member can move in the adjustment direction, the bending load on the adjustment screw is reduced.Type: GrantFiled: April 30, 1999Date of Patent: May 15, 2001Assignee: Kennametal Hertel AG Werkzeuge + HartstoffeInventors: Gebhard Müller, Horst Jäger, Martin Voll

Patent number: 6142485Abstract: A chuck for rotary tools with a cylindrical chucking shank encloses such shank with a basic body. A radial through-hole in basic body serves to receive a clamping screw which applies pressure to a clamping member which is seated inside a through-hole between the clamping screw and chucking shank. A clamping member is provided with a radial projection and the through-hole with a cross-sectional narrowing along its inner end. In between the radial projection and the narrowing is an elastically compressible spring element which, due to its return force, lifts the clamping element away from the chucking shank and pushes it back into the through-hole when it is not under tension from the clamping screw.Type: GrantFiled: April 30, 1999Date of Patent: November 7, 2000Assignee: Kennametal Inc.Inventors: Gebhard Muller, Michael Schuffenhauer, Martin Prey

Patent number: 5915895Abstract: A rotary tool for drilling and chamfering, which takes place in one common advance, essentially comprises a base body, a drill clamped centered therein and a chamfering tool disposed on the end of the base body toward the drill tip and having a cutter body tip disposed next to the flank of the lateral free face of the drill. The chamfering tool can be radially adjusted in relation to the drill in a direction pointing at right angles in respect to the drill axis.Type: GrantFiled: December 22, 1994Date of Patent: June 29, 1999Assignee: Kennametal Hertel AG Werkzeuge and HartstoffeInventors: Horst Jager, Michael Schuffenhauer, Gebhard Muller, Bernhard Borschert, Ulrich Krenzer

Patent number: 5848858Abstract: A milling cutter is provided with a base body that can be driven in a rotating manner around its longitudinal axis. Support bodies are distributed over the surface of the base body and are supported from centrifugal forces by a base body stopper and are positioned in tension against the base body stopper. The base body has an end face with a central area and a peripheral area around the central area, which central area is recessed with respect to the peripheral area. The central area and peripheral area together forming a step which acts as the base body stopper. The support bodies comprise a counter-step which can interlock with the base body, and a mounting plate is positioned at the end face to support the support bodies.Type: GrantFiled: September 24, 1996Date of Patent: December 15, 1998Assignee: Kennametal Hertel AGInventors: Horst Jager, Gebhard Muller

Patent number: 5810527Abstract: A rotary tool, in particular a high-speed milling or boring tool, has at least two balancing rings (17, 18) with a variable mass around their circumference mounted on the tool holder or tool body (1). Two concentric balancing rings (17, 18) whose position in relation to the axis of rotation (6) of the tool (1) may be adjusted are releasable mounted in the tool holder or in the tool body (1) and are supported in the radial direction (14) in the tool holder or tool body (1). A short rotary tool (1) is thus obtained with a simple support of the balancing rings (17, 18) in the radial direction.Type: GrantFiled: September 18, 1996Date of Patent: September 22, 1998Assignee: Kennametal Hertal AGInventors: Horst Jager, Gebhard Muller

Patent number: 5186584Abstract: A twist drill has a cutting member at the bottom, a shaft at the top, and a reduced-diameter root clearance region between the cutting member and the shaft. Cutting edges are provided at the transition between the cutting member and the root clearance region, and further cutting edges are provided at the transition between the shaft and the root clearance region. After a throughhole has been drilled using the cutting member, the drill is displaced laterally and moved along a circular path while it is still rotating. As a result, the cutting edges at the transition between the cutting member and the root clearance region countersink the bottom end of the throughhole. A similar procedure is employed to countersink the top end of the throughhole using the further cutting edges at the transition between the shaft and the root clearance region.Type: GrantFiled: June 27, 1991Date of Patent: February 16, 1993Assignee: Hertel AG Werkzeuge & HartstoffeInventors: Gebhard Muller, Simon Escher
