Patent number: 9724883Abstract: The invention relates to a method for producing a tubular hollow body (1) with at least three pipe openings, partly or completely consisting of plastics material. It is provided that a lost core pipe (9), which has a connection opening (13, 14) on each of its ends and has at least one docking opening (11) along its length, is produced, that the core pipe (9) is introduced into a cavity of a mold, with two non-lost core pieces (17, 18) being arranged with one of their ends (3, 4) respectively against the connection openings (13, 14) in a sealing manner and a non-lost core part (19) being arranged with one end against the docking opening (11) in a sealing manner, in that plastics material (25) is then introduced into the mold cavity to encapsulate the core pipe (9), the core pieces (17, 18) and the core part (19) and that, once the plastics material (25) has cured, the core pieces (17, 18) and the core part (19) are withdrawn from the hollow body (1) created.Type: GrantFiled: January 7, 2014Date of Patent: August 8, 2017Assignee: Georg Fischer JRG AGInventors: Erasmo Porfido, Peter Heer, Markus Breyer

Patent number: 5964482Abstract: In a connection between a pipe and a molding, a tubular housing, fixed on the molding, engages around the pipe with an inner wall tapering conically toward the free end of the housing. Arranged between the pipe and the housing inner wall is a clamping ring, which braces the pipe with the housing in a wedge-like manner. The clamping ring is held in its wedging functional position by a spring element acting on it in the axial direction. The spring element can be locked in a prestressed state without force acting on the clamping ring. To establish the connection between the pipe and the molding, a locking clip passing through the housing is pulled out of the housing to relax the spring element.Type: GrantFiled: November 5, 1997Date of Patent: October 12, 1999Assignee: Georg Fischer Rohrleitungssysteme AGInventors: Michael Bamberger, Erasmo Porfido, Bernd Kling

Patent number: 5911895Abstract: An apparatus for simultaneously welding multiple molded plastic parts includes a power delivery module, a measuring arrangement, a parameter storage module, a user interface, and a controller, is designed for use with plastic parts that each have at least one fitting with a heating element and an identifying resistor. The power delivery module is designed to supply power to the multiple heating elements and includes a common power supply, multiple independently controllable power switching devices and multiple outputs, each designed for interconnection with one of the fittings. The measuring arrangement includes multiple interconnections for connecting to the heating element and identifying resistor of each fitting to which an output is connected. The measuring arrangement measures the resistance of the heating element and the identifying resistor of each fitting connected to the apparatus.Type: GrantFiled: March 26, 1997Date of Patent: June 15, 1999Assignee: Georg Fischer Rohrleitungssyteme AGInventors: Erasmo Porfido, Jurg Steiner

Patent number: 5674588Abstract: A welding sleeve includes a sleeve body having a recess for receiving a plug contact. The recess has sidewalls and a bottom wall. The bottom wall is provided with a projection which defines with the side walls of the recess a pair of slots. The plug contact includes an insertion part adapted to be received within the recess. The insertion part includes leg portions to be received in the slots of the recess and a slit between the legs adjacent the top surface of the projection. The slit receives a portion of the heating element which rests on the top surface of the projection. The width (b) of the slit is less than the diameter (d) of the heating element so as to insure good electrical contact.Type: GrantFiled: June 12, 1995Date of Patent: October 7, 1997Assignee: Georg Fischer Rohrleitungssysteme AGInventors: Erasmo Porfido, Dirk Alexander Petry
