Patent number: 7248154Abstract: The invention relates to a system and a method for the detection of the wear state of machine parts which are subject to mechanical wear, by means of an electronic transmitting/receiving device (38) and at least one transponder device (36), which is embedded in the machine part (16) and sends back an acknowledgement signal in response to a transmitted signal which is transmitted by the transmitting/receiving device (38), in which case the reaching of a predetermined wear value can be indicated by the destruction of the transponder device (36) and by the lack of the acknowledgement signal associated with this. The invention is based on the discovery that the arrangement of a transponder device at a specific position which is a measure of a predetermined wear state means that the operational readiness of the transponder device, on the one hand, is indicated in advance by its signal return, and the reaching of the predetermined wear value is indicated by its destruction.Type: GrantFiled: April 8, 2005Date of Patent: July 24, 2007Assignee: Meri Entsorgungstechnik fur die Papierindustrie GmbHInventor: Lucas Menke

Patent number: 6773586Abstract: A flotation device for separating materials or mixtures of materials from suspensions includes a reaction and mixing space (18) with eccentric inlet (16) for the mixture of suspension particles with gas bubbles and for further transport into at least one centrally arranged vertical suspension distribution tube (26), wherein the suspension distribution tube (26) and the clarified fluid collecting tube (48) are arranged adjacently, the plates (30) surround the suspension distribution tube (26) and the clarified fluid collecting tube (48) in an annular manner; and every second annular plate space (31) between adjacent plates (30) is connected to the suspension distribution tube (26) and every other space (31) between plates is connected to the clarified fluid collecting tube (48), so that the flow takes place out of one space (31) between plates from the inside towards the outside to the separating space (32), and subsequently into an adjacent space (31) between plates from the outside towards the inside.Type: GrantFiled: September 26, 2001Date of Patent: August 10, 2004Assignee: Meri Entsorgungstechnik für die Papierindustrie GmbHInventors: Lucas Menke, George Troubounis

Patent number: 6641724Abstract: The invention relates to a device and a method for chemically and physically separating solid materials from a suspension using flotation. A rotationally symmetrical flocculation/flow reactor is provided with outlets in the lower part thereof and is arranged in a separating tank. At least one suspension inlet extends eccentrically into said reactor. The supplied suspension is guided into said reactor. The supplied suspension is guided into the upper area of the flocculation reactor via the suspension inlet. A circular flow is thus created which drains off from the flocculation reactor downwards in a tangential and radial manner over the outer circumference into circularly arranged distribution cells which reinforce the tangential component of the suspension flow when said flow is delivered into the separating tank. In prior art, the flow of the mixture consisting of the suspension and air-sacs extends radially outwards.Type: GrantFiled: July 20, 2001Date of Patent: November 4, 2003Assignee: Meri Entsorgungstechnik fur die Papierindustrie GmbHInventors: Bernhard Niemczyk, Robert Heinz, Lucas Menke, George Troubounis
