Publication number: 20240065145Abstract: The present disclosure relates to a mower knife device with a knife bar and a dual blade cutting system. The dual blade cutting system includes an upper cutting knife and a lower cutting knife designed to be movable relative to one another. The upper cutting knife is connected to the knife bar by means of an upper retaining device. The lower cutting knife is connected to the knife bar by means of a lower retaining device. The upper retaining device is mounted on the knife bar by means of a guide bushing. A preloaded tension spring is arranged inside the guide bushing. The tensile force of the tension spring is designed to apply a contact pressure of the upper cutting knife to the lower cutting knife via the upper retaining device.Type: ApplicationFiled: October 28, 2021Publication date: February 29, 2024Applicant: Wepfer Technics AGInventor: Hans WEPFER

Patent number: 10378514Abstract: The present invention relates to wind turbine installations for power generation. The wind turbine installations comprise a turbine support with at least two wind turbines. Furthermore, a wind turbine installation according to the invention comprises a tower console with at least one bearing point. Said bearing point permits a rotational movement of the turbine support about the vertical axis of the turbine support and relative to a foundation. The turbine support is connected to the tower console by means of tower pillars. The installation furthermore comprises electronics which comprise an electronic controller. The electronics are furthermore designed so as to be rotatable about the vertical axis of the turbine support relative to the foundation and relative to a power transmission cable.Type: GrantFiled: November 15, 2013Date of Patent: August 13, 2019Assignee: WEPFER TECHNICS AGInventor: Hans Wepfer

Patent number: 10065245Abstract: The present invention relates to a device for deburring tubes, in particular tube ends. Said device comprises a proximal and a distal end and has a substantially basic body (1) with a plurality of contact surfaces (20, 20?, 20?). It further includes a shaft (2) and a guide chamber (4) in which a guide bushing (6) is displaceably mounted. A spring (5) is arranged in such a manner in the guide chamber (4) that a restoring force is exerted onto the guide bushing (6). A blade (11) is releasably fastenable on the guide bushing (6). A guide groove (19), by means of which the blade (11) is guided, extends along an outside surface of the conical basic body (1). The present invention further relates to the use of the device according to the invention for deburring tubes (17), in particular tube ends.Type: GrantFiled: May 9, 2014Date of Patent: September 4, 2018Inventors: Hans Wepfer, Kenneth Wohlgensinger
