Patent number: 9180513Abstract: Process and casting mold for producing a cast wheel. A core, which remains in the cast wheel and has a circumferential rim, is inserted into a casting mold having at least one lower mold part and an upper mold part moved relative to one another to close casting mold. Core is positioned by at least one positioning element in a predetermined position in casting mold, so that an end region of positioning element is fixed with a force fit or frictional fit in circumferential rim of the core. A free end region of positioning element, which protrudes from circumferential rim of the core, is placed on a contact surface, which is preferably arranged substantially horizontally during operation, of lower mold part during positioning of core in casting mold. Core is positioned in the predetermined position under the action of the force of gravity.Type: GrantFiled: December 2, 2011Date of Patent: November 10, 2015Assignee: BORBET AUSTRIA GMBHInventors: Helmuth Huber, Manfred Johannes Ebetshuber, Josef Gartner

Patent number: 4966188Abstract: A pneumatically operated gas-pressure controller is provided having a setting device and a controller, wherein the controlling gas for the energy supply of the controller is drawn on the input side of the gas-pressure controller, fed to the controller by means of a throttle valve and discharged on the outlet side by means of a drain conduit. The controller supplies the setting pressure for the setting device by means of a setting pressure conduit and includes a twin diaphragm system having two diaphragms with different surface areas, the diaphragms are interconnected and arranged one above the other so as to oppose one another. A booster valve is associated with the diaphragm having the smaller surface area and is acted upon by the setting pressure.Type: GrantFiled: August 16, 1989Date of Patent: October 30, 1990Assignee: Regal + Messtechnik GmbHInventors: Rudolf Fischer, Josef Gartner
