Patent number: 10697574Abstract: A tapping saddle for a plastic main pipe carrying a medium includes a stub having a central axis, a saddle piece, and a drill. The drill is configured to be moved axially in the stub. A heating element geometry, which is used for welding the tapping saddle to a main tube outer circumference, is arranged on an inside diameter of the saddle piece. The heating element geometry has a winding having an outer winding region and an inner winding region. In the inner winding region, the winding extends in meandering loops along a circle concentric with the central axis of the stub.Type: GrantFiled: April 19, 2018Date of Patent: June 30, 2020Assignee: GEORG FISCHER WAVIN AGInventors: Jonas Huessy, Dirk Petry, Edwin Habluetzel

Patent number: 10648593Abstract: A pipe clamp for a main pipe conveying a medium. The pipe clamp includes a saddle member and bearing elements, wherein the bearing elements are arranged on the saddle member. The pipe clamp further includes a tension unit, wherein the tension unit comprises at least one band for encircling the main pipe, a band linkage, and a clamping lever. The band linkage and the clamping lever are each arranged at one end of the at least one band and are opposite one another. An extension is arranged on the clamping lever, and the extension is configured to be removed from the clamping lever after the tension unit is firmly clamped on the main pipe.Type: GrantFiled: January 17, 2019Date of Patent: May 12, 2020Assignee: GEORG FISCHER WAVIN AGInventors: Oliver Trefz, Jonas Huessy, Dirk Petry

Patent number: 6717541Abstract: A low resolution data acquisition system is presented. The data acquisition system has a plurality of readout modules serially connected to a controller. Each readout module has a FPGA in communication with analog to digital (A/D) converters, which are connected to sensors. The A/D converter has eight bit or lower resolution. The FPGA detects when a command is addressed to it and commands the A/D converters to convert analog sensor data into digital data. The digital data is sent on a high speed serial communication bus to the controller. A graphical display is used in one embodiment to indicate if a sensor reading is outside of a predetermined range.Type: GrantFiled: April 29, 2003Date of Patent: April 6, 2004Assignee: Iowa State University Research Foundation, Inc.Inventors: David Carter-Lewis, Frank Krennich, Stephane Le Bohec, Dirk Petry, Gary Sleege

Patent number: 5386101Abstract: For welding tubular plastic parts (1) formed as a compound tube there is used a welding element (20) which is arranged with its inner peripheral surface (23) on projections (10) of the tubular parts (1) and reciprocally centers them. The welding element (20) has an annular part (21) with a heating coil (22) on its outer contour. The heating coil (22) has coil strands laid in a zig-zag shape which are curved in a U-shape and extend transversely to the peripheral direction of the annular part (21).Type: GrantFiled: July 2, 1993Date of Patent: January 31, 1995Assignee: Georg Fischer Rohrleitungssysteme AGInventors: Hans W. Steinmetz, Dirk A. Petry
