Patent number: 7150590Abstract: A machining tool, especially a milling tool, includes a shaft-like holder defining a longitudinal axis (13). A seat (9) is provided in the front face of the holder for a cutting plate that can be inserted into the holder. The cutting plate has a coupling part for mounting in the seat (9) of the holder. The coupling part has three ribs which project axially from the end surface of the cutting plate that is opposite the holder and which extend radially. The ribs are provided for engagement in complementary grooves (31) configured in the seat (9) of the holder. Their side walls (37 and 35) form driving surfaces and support surfaces, which interact for transmitting a machining torque, or as axial position safety-catch, with corresponding surfaces of the flanks of the ribs of the cutting plate.Type: GrantFiled: March 25, 2003Date of Patent: December 19, 2006Assignee: Hartmetall-Werkzeugfabrik Paul Horn GmbHInventors: Hans Schäfer, Matthias Oettle

Patent number: 6524434Abstract: A tube-forming apparatus in a bag-forming, filling, and sealing machine has a longitudinal seam heat-sealing device for connecting edge regions of the packing material belt that are placed against each other inside surface to inside surface. In order to achieve a sufficient sealing temperature in a short time, a heating body that is embodied in a lamella-like fashion protrudes like a tongue between the edge regions. In order to aid the heating body, similar heating bodies rest against the outside of the edge regions. The heating bodies have a U-shaped electric resistance wire with elongated legs which is embedded in a longitudinally folded casing made of a thin, temperature-proof woven cloth.Type: GrantFiled: September 25, 2000Date of Patent: February 25, 2003Assignee: Robert Bosch GmbHInventors: Klaus Domke, Herbert Stotkiewitz, Wolfgang Bloch, Frank Kurz, Alexander Lutz, Hans Schaefer, Helmut Rumes

Patent number: 4370830Abstract: A sliding window with a frame provided with a glazing adapted to be mounted in a wall of masonry, wood, or the like. The frame is composed of frame profiles joined at the corners and contains glass panes inserted therein. The glass panes are guided in grooves of the frame profiles and are horizontally displaceable. The frame profile members are constructed of an extrudable synthetic resinous material, with the profile members having a U-shaped cross sectional configuration made up of two projections fashioned as hollow chambers. An undercut mounting groove is arranged between the two projections and a web, connecting the projections, is formed of two juxtaposed hollow chambers. One of the juxtaposed hollow chambers facing a weather side of the window is provided with perforations for draining the mounting groove, with a second of the juxtaposed hollow chambers containing, if desired, an inserted reinforcing profile.Type: GrantFiled: October 7, 1980Date of Patent: February 1, 1983Assignee: Dynamit Nobel AktiengesellschaftInventors: Hans Schaefer, Wolfgang Budich
