Patent number: 6305208Abstract: An edging device or hemming device is disclosed with a machine frame (1), an edging bed (2) which is positioned inside said frame where it is raised and lowered with an edging lift and/or a displacement lift. A plurality of edging jaws are provided, which can be moved into the working area of the edging bed (2). Drive mechanisms are provided for the edging bed (2) and the edging jaws (3). The drive mechanisms for the edging lift and the displacement lift are configured as electromechanical drive mechanisms (7) which move the edging bed (2) using driven eccentric cams (12) or cranks. This simplifies the control of the drive mechanisms and reduces the masses of the structural parts being moved.Type: GrantFiled: July 13, 2000Date of Patent: October 23, 2001Assignee: Thyssen Krupp Technologies AGInventor: Erich Zimmer

Patent number: 6282751Abstract: A hinge connection at a breathing gas supply unit between a container lower part (3) and a container door (4), which is fastened, pivotably around an axis, at a rear container edge (1) of the container lower part (3). The connection is provided such that dimensional differences of the container lower part can have only a limited effect on the positioning of the container door in relation to adjacent components of the breathing gas supply unit. The axis of the hinge is designed as projections (15) located at a spaced location from hinge pins (14) of a rail section (2) in the manner of a pin.Type: GrantFiled: June 7, 1999Date of Patent: September 4, 2001Assignee: Drager Aerospace GmbHInventors: Roderich Thometschek, Carsten Mantey, Ralf Göke

Patent number: 6279261Abstract: In a process for thermal pest control, a fuel-operated heater with separate flue gas routing is used to heat up a space to be treated. Fumigants may be additionally introduced into the air of the space to be treated, especially if the combustion chamber 13 of the heater is separated from the heat exchanger chamber 8 of the heater in a gas-tight manner. The process is particularly suitable for disinfecting mills and food-processing plants.Type: GrantFiled: May 25, 1999Date of Patent: August 28, 2001Assignee: Binker Materialschutz GmbHInventors: Gerhard Binker, Joachim Binker

Patent number: 6276758Abstract: A continuously operating surface miner designed basically with a milling roller for the accurate, selective mining of sedimentary beds. The parameters cutting height, cutting width and feed speed are decisive for the performance capacity of surface miners. How the miner begins a block to be mined, how it finishes it and changes over to a new block to be mined is significant as well. The particular technology that can be used depends essentially on the mobility of the miner and the possibility of the engagement of the milling roller with the material to be mined. A three-caterpillar chassis for the miner and for arranging the milling roller (15a) in front of the said chassis in the direction of mining is provided. The milling roller (15a) is mounted on a transverse frame (15b) and is fastened by same to the superstructure (8) of the miner. High mobility of the miner is achieved due to this arrangement of the milling roller and the use of the chassis.Type: GrantFiled: August 30, 1999Date of Patent: August 21, 2001Assignee: Man Takraf Fördertechnik GmbHInventors: Dieter Hoffmann, Volkmar Schrader, Thomas Stenzel, Hans-Joachim Schombel

Patent number: 6276930Abstract: Orthodontic bracket having a retention base for a respective tooth and identifying indicia in relation to the tooth for which the orthodontic aid is suitable. The indicia includes a sign provided on the back side of the retention base. The size of the indicia is at least 3 square millimeters. The indicia has substantially null depth with respect to the retention base, thus following the outer profile of the latter.Type: GrantFiled: November 19, 1999Date of Patent: August 21, 2001Assignee: Leone S.p.A.Inventor: Alessandro Pozzi

Patent number: 6273485Abstract: A parallel pneumatic gripper is provided with body (11) and jaws (13), which are pieces of extruded elements made of aluminum or its alloys, finished by means of extrusion and designed to be joined in a complementary manner. In addition, this pneumatic gripper has a control piston (14) that accommodates and is moved in a chamber (25) defined by two heads (12) inserted and fixed to the opposite ends of the body.Type: GrantFiled: April 16, 1999Date of Patent: August 14, 2001Assignee: Gimatic S.p.A.Inventors: Giuseppe Maffeis, Giuseppe Bellandi

Patent number: 6179349Abstract: A system of elements for the formation of pipelines in units for channeling and distributing a gaseous or liquid fluid that is under pressure or under vacuum. The pipelines are created starting from an extruded section pipe with a four-sided cross section having at least one central longitudinal hole and gripping elements along the corners of its walls. A joint which can be inserted tightly into the hole of consecutive section pipes makes possible their connection with the transmission of fluid. A fixing clamp is mounted on the adjacent ends of the consecutive pipes and engages with the gripping elements to mechanically lock the pipes among one another.Type: GrantFiled: November 12, 1998Date of Patent: January 30, 2001Assignee: Teseo S.R.L.Inventor: Paolo Guzzoni

Patent number: 6155466Abstract: Apparatus for the opening or stretching apart of one end (10) of a tubular article (1), comprising a body (T) of substantially tubular shape, with an entry section (I) of the end (10) of the articles (1) to be treated and communicating with air suction means, in which downstream of the section (I) a converging-diverging conduit (2) is provided downstream of which, at a predetermined distance, there is a pin member (3) on which the end (10) of the article is to be fitted by virtue of the suction and of the expansion or opening caused by its transit along the region (20) downstream of the conduit (2). The body (T) is made up of two portions separable with respect to a central longitudinal plane (x--x) at least in correspondence of the above mentioned pin member (3) to allow the removal of the article (1) with its end (10) in streteched condition. (FIG. 1).Type: GrantFiled: October 14, 1999Date of Patent: December 5, 2000Assignee: Matec S.p.A.Inventor: Pier Lorenzo Migliorini
