Patent number: 9464180Abstract: There is provided a method of fabricating a composite material, the method comprising providing borehole solids originating from a borehole in the earth and embedding the borehole solids in a base material thereby forming the composite material, wherein the base material comprises a polymer. According to an embodiment, the borehole solids contain oil, e.g. on a surface thereof. The oil containing borehole solids may be preprocessed before embedding or may be directly embedded in the base material without preprocessing. Such embodiments allow for a recycling of oil contaminated borehole solids while providing a resource for a filler for polymers.Type: GrantFiled: September 14, 2012Date of Patent: October 11, 2016Assignee: Montanuniversität LeobenInventors: Herbert Hofstätter, Clemens Holzer

Publication number: 20140144847Abstract: A system for at least partially removing a contaminant in a contaminated fluid includes a reaction vessel with a fluid inlet and a fluid outlet. The contaminated fluid is conductable in a fluid flow direction which has at least a component oriented antiparallel to the force of gravity. A fluid supply unit supplies a contaminated fluid through the fluid inlet inside the reaction vessel. The reaction vessel is filled with reactive particles. The fluid supply unit controls a flow velocity of the contaminated fluid between the fluid inlet and the fluid outlet so that the flow of contaminated fluid through the reactive particles generates a fluidized bed of the reactive particles, thereby removing, at least partially, the contaminant in the contaminated fluid by a reaction of the contaminant and the reactive particles. At least 80% of the reactive particles have a size of more than 2 mm.Type: ApplicationFiled: October 31, 2011Publication date: May 29, 2014Applicant: MONTANUNIVERSITAET LEOBENInventors: Peter Mueller, Robert Mischitz, Christian Weiss

Patent number: 8679383Abstract: A method of determining a residence time distribution comprises mixing a molding batch (104) and a tracer (105), wherein the tracer has a ferroelectric curie temperature above 120° C., and transmitting the mixture through a capacitor (107). Further, the method comprises measuring a capacitance of the capacitor, and determining a residence time distribution based on the measured capacitance. In particular, the ferroelectric curie temperature of the tracer may be above 150° C. and preferably the ferroelectric curie temperature of the tracer is above 200° C.Type: GrantFiled: December 28, 2007Date of Patent: March 25, 2014Assignee: Montanuniversitaet LeobenInventors: Wolfgang Reinberger, Beatrix Lederer

Patent number: 8523542Abstract: The present invention describes a pumping device (1) for pumping fluids. The pumping device (1) comprises a force transmitting element (2), a tension unit (3) coupled to the force transmitting element (2) and a seal element (10). The force transmitting element (2) is adapted for transferring an upstroke and a downstroke to a pump plunger (5) for pumping fluid (12). The tension unit (3) is adapted for applying a tension force (F) to the force transmitting element (2) for keeping the force transmitting element (2) under tension during the upstroke and the downstroke. The seal element (10) is adapted for sealingly preventing pumping fluids (12) during the downstroke and for enabling pumping fluid (12) during the upstroke. A part (16) of the seal element (10) is rigidly coupled with the force transmitting element (2).Type: GrantFiled: June 2, 2008Date of Patent: September 3, 2013Assignee: Montanuniversitaet LeobenInventor: Herbert Hofstätter
