Publication number: 20110137515Abstract: A method of operating a hydraulic or a pneumatic control device of a semi-automatic transmission. The control device has actuator devices with actuating cylinders. Pressure chambers of the actuating cylinders can each be connected, via a control valve, with a pressure line that can be selectively connected with a main pressure line, or blocked, via redundant and parallel positioned main switching valves. The control device has at least one sensor and at least one measured signal is captured by the at least one sensor, depending on the actuation of the main switching valves. The at least one measured signal or each captured measured signal is compared to a stored nominal signal for the respective actuation of the main switching valves and, if a deviation is determined between the measured signal and the respective nominal signal, a defect of at least one of the main switching valves is concluded.Type: ApplicationFiled: July 9, 2009Publication date: June 9, 2011Applicant: ZF FRIEDRICHSHAFEN AGInventors: Mario Steinborn, Alfred Bruhn, Rainer Petzold

Publication number: 20090085765Abstract: The invention relates to an arrangement and a method for providing at least one operating function of a remote control for operating a device (14 to 20), in which the device (14 to 20) has a storage area in which data containing information relating to this operating function are stored. Provision is also made of a data link between the device (14 to 20) and the remote control (22), which link can be used to transmit data containing the information relating to this operating function from the device (14 to 20) to the remote control (22), the remote control (22) having a data processing unit which processes the information transmitted from the device (14 to 20) to the remote control (22) and, on the basis of this information, provides at least one operating function using at least one operating element (24, 26) of the remote control (22) and/or assigns this operating function to an operating element (24, 26) of the remote control (22).Type: ApplicationFiled: August 29, 2008Publication date: April 2, 2009Applicant: MAQUET GmbH & Co. KGInventor: Alfred Bruhn

Patent number: 5279356Abstract: These and other objects of the present invention are achieved in a heat recovery system to recover the heat potential and including a plurality of heat exchanger assemblies from exhaust or waste gas at a temperature of from 500 to 2500.degree. F. wherein the heat exchanger assemblies include induced draft fans for controlling the flow of exhaust or waste gas therethrough as a heating medium for diverse fluids passing in indirect heat transfer relationship at descending temperature levels.Type: GrantFiled: January 25, 1991Date of Patent: January 18, 1994Assignee: American Hydrotherm CorporationInventor: Alfred Bruhn

Patent number: 5133191Abstract: A heat recovery system includes a storage tank for an intermediate heat transfer fluid and a heat exchanger for receiving an intermittent flow of heated stack gas from a reheat furnace, whereby heating values from the stack gas are transferred to the heat transfer fluid. The system includes a steam generator and the heating values acquired by the heat transfer fluid are used to generate and to superheat the steam. The heat transfer medium is controlled so that the flow of superheated steam produced is substantially steady. The heated stack gas may be used to preheat boiler feed water used for steam generation. The processes used are also described.Type: GrantFiled: January 29, 1991Date of Patent: July 28, 1992Assignee: American Hydrotherm CorporationInventors: Alfred A. Bruhn, Gregory P. Schneck
