Patent number: 11198633Abstract: A process and a plant produce hollow microspheres made of glass. According to the process an aqueous suspension is prepared from starting materials containing glass powder and water glass, feedstock particles having a diameter between 5 ?m and 300 ?m, in particular between 5 ?m and 100 ?m, being produced from the suspension. The feedstock particles are mixed with a pulverulent release agent made of aluminum hydroxide in an intensive mixer. The mixture of feedstock particles and release agent is subsequently introduced into a firing chamber of a furnace. The feedstock particles expand in the firing chamber, at a firing temperature which exceeds the softening temperature of the glass powder, to form the hollow microspheres.Type: GrantFiled: November 13, 2018Date of Patent: December 14, 2021Assignee: Dennert Poraver GmbHInventors: Karl Weinberger, Wolfram Neidhardt

Patent number: 10696522Abstract: A method for refinishing a surface structure of shaft material of an elevator, which extends along a shaft, enables the use of image data to determine an absolute position and/or speed of an elevator car. The elevator includes the elevator car, which is movable in the shaft, a camera, which is arranged at the elevator car and generates the image data from the surface structure, and an evaluating unit, which determines the absolute position and/or the speed of the elevator car from the image data. The surface structure is refinished at least locally in order to increase a distinctiveness of the surface structure in the image data. The shaft material can be, for example, a guide rail, a fastening element of the guide rail, or a shaft wall.Type: GrantFiled: December 14, 2015Date of Patent: June 30, 2020Assignee: INVENTIO AGInventors: Raphael Bitzi, Karl Weinberger

Patent number: 10435328Abstract: In a method for producing an expanded-glass granular material, starting materials containing glass powder, water glass, at least one blowing agent, and metakaolin, are mixed in order to form a homogeneous slurry. The slurry is granulated to form raw granular-material particles, which are foamed at a baking temperature between 780° C. and 950° C. in order to form expanded-glass granular-material particles. The expanded-glass granular material has a long-term water absorption of less than 25 volume percent when the expanded-glass granular material is exposed to water for a time period of 21 days.Type: GrantFiled: August 3, 2017Date of Patent: October 8, 2019Assignee: Dennert Poraver GmbHInventor: Karl Weinberger

Patent number: 9969637Abstract: A process and an associated facility for treating ammonium-containing wastewater are specified. Ammonium present in the wastewater is first oxidized to nitrite by use of aerobically oxidizing bacteria in an activation unit. Then ammonium and nitrite are reduced to elemental nitrogen anaerobically by use of ANAMMOX bacteria. Excess sludge arising in this operation is removed from the activation unit. ANAMMOX bacteria removed with the excess sludge are separated and returned to the activation unit. To facilitate the returning of the ANAMMOX bacteria, magnetic or magnetizable expanded glass particles are added, as colonization bodies for the ANAMMOX bacteria, to the wastewater in the activation unit. Expanded glass particles removed from the activation unit with the excess sludge are separated from the excess sludge magnetically and returned to the activation unit.Type: GrantFiled: July 18, 2016Date of Patent: May 15, 2018Assignee: Dennert Poraver GmbHInventor: Karl Weinberger

Publication number: 20170279397Abstract: A passenger transport system includes a three-phase drive motor, a control device and an inverter module having power semiconductor switches. The gate electrodes of the power semiconductor switches are driven directly by the control device. The inverter module is connected on the input side to a DC source and on the output side to the three-phase drive motor. Between the DC source and the inverter module there is a DC circuit, wherein drive signals that can be modulated on the DC circuit can be generated by the control device, and the inverter module has a demodulator, by which demodulator the drive signals can be converted into control voltages assigned to the individual gate electrodes of the power semiconductor switches.Type: ApplicationFiled: July 21, 2015Publication date: September 28, 2017Inventors: Esteban Marks, Michael Matheisl, Karl Weinberger

Patent number: 8016081Abstract: An elevator drive with a brake device has compression springs that act on brake levers, whereby brake linings generate a brake force on a brake drum. The more the brake linings wear due to abrasion, the smaller the distance of the plunger from the brake magnet housing becomes. Should the plunger come into contact with the brake magnet housing, the braking capacity of the brake linings is completely eliminated creating an operating condition that is dangerous for elevator users. A switch is provided that detects a minimum distance. The switch can be arranged on the plunger of the brake magnet and detect the minimum distance to the brake magnet housing or, in the case of a retrofit, the switch can be arranged on the brake magnet rod and, for example, detect the distance of the second joint from the brake magnet housing, and at the minimum distance the switch switches.Type: GrantFiled: June 16, 2008Date of Patent: September 13, 2011Assignee: Inventio AGInventors: Karl Weinberger, Rudolf Eckenstein, Rene′ Hermann, Luc Bonnard
