Patent number: 11661324Abstract: A materials handling vehicle comprises an operator compartment, a compartment tower, a multi-field scanning tool, and mechanisms that facilitate movement along a travel plane in a warehouse. The tool establishes a scan field, and, within scan field bounds, an occupancy detection field and an obstacle detection field. Tool scanning hardware is configured to generate the scan field from a point of origin that is elevated relative to the operator compartment and to expand the scan field such that it intersects the operator compartment and extends laterally beyond lateral edges of the operator compartment such that the occupancy detection field falls within the operator compartment, the obstacle detection field falls outside of the operator compartment, and the multi-field scanning tool is configured to indicate the presence of an occupant in the occupancy detection field and obstacles in the obstacle detection field.Type: GrantFiled: May 31, 2022Date of Patent: May 30, 2023Assignee: Crown Equipment CorporationInventors: Franz Pöschl, Timothy A. Wellman, Stefan Hanneman, Martin Okroy, Stefan Sauer, Jess Donnely

Patent number: 6685117Abstract: In a mill drying plant with a roller grinding mill and preferably in a cement production plant operated in compound with a clinker burning process and having a kiln fan and a fan downstream of a filter, a mill fan is connected upstream of the roller grinding mill as a further fan. This makes it possible to overcome the resistance of the roller grinding mill blade ring and to force the pressure zero point into the roller grinding mill, so that there is a low vacuum above the blade ring in the milling and classifying chamber and in the filter.Type: GrantFiled: August 15, 2001Date of Patent: February 3, 2004Assignee: Loesche GmbHInventor: Franz Poeschl

Patent number: 6276620Abstract: In a mill drying plant with a roller grinding mill and preferably in a cement production plant operated in compound with a clinker burning process and having a kiln fan and a fan downstream of a filter, a mill fan is connected up-stream of the roller grinding mill as a further fan. This makes it possible to overcome the resistance of the roller grinding mill blade ring and to force the pressure zero point into the roller grinding mill, so that there is a low vacuum above the blade ring in the milling and classifying chamber and in the filter.Type: GrantFiled: August 4, 1999Date of Patent: August 21, 2001Assignee: Loesche GmbHInventor: Franz Poeschl

Patent number: 5115989Abstract: The invention relates to a dynamic roller mill air classifier, which is provided in integrated manner over a roller mill. As existing air classifiers suffered from certain disadvantages with respect to the specific energy requirement, the invention makes it possible to reduce the latter. The air classifier is designed as a downflow classifier, which classifies in an efficient manner with reduced flow rates.Type: GrantFiled: February 19, 1991Date of Patent: May 26, 1992Assignee: Loesche GmbHInventor: Franz Poeschl
