Publication number: 20220274296Abstract: A device and a method for loading prefabricated parts into a molding tool of a press for the production of molded parts, in particular for the production of elastomer molded parts. For this purpose, the device comprises a plate-like carrier element with a top and a bottom intended for attachment on or to the press and a holding device for accommodating at least one interchangeable platen equipped with the parts. The holding unit is arranged on the supporting element at a clear distance from its bottom and the interchangeable platen comprises a plurality of passage openings to accommodate the parts. Furthermore, the device comprises a platen with pins which are arranged between the bottom of the supporting element and the holding unit, wherein the pins align with the passage openings.Type: ApplicationFiled: March 1, 2022Publication date: September 1, 2022Applicant: Wickert Maschinenbau GmbHInventors: Florian SCHRAMM, Stefan HERTEL

Publication number: 20060106641Abstract: A mobile monitoring and communication system integrates communication services (text, voice, video, and data) with medical information (e.g., patient medical record, patient demographics, reason for procedure, workflow information, etc.) within a radiology department, for example. A medical information system for use with portable processing devices involves a portable processing device including a communication processor for receiving messages from one or more different healthcare workers. An individual message identifies, a task for performance by a particular healthcare worker for a patient, patient and task associated context information and a priority level of the task. A user interface provides data representing at least one display image for display to a user and comprising an overview of tasks of the different healthcare workers including the task for performance by the particular healthcare worker.Type: ApplicationFiled: April 26, 2005Publication date: May 18, 2006Inventors: Ernst Bartsch, Brian DelMonego, Betty Fink, Gary Grzywacz, Stefan Hertel, Susanne Laumann, James Pressler, Ramesh Ramanujam, Donald Taylor, Arnold Teres
