Patent number: 8439052Abstract: An electric household appliance has a chamber that is at least partially filled with liquid during operation of the appliance. A motor drives a pump for drawing liquid from the chamber. A monitoring device detects the rotational speed and the power of the motor, compares detected values for the rotational speed and power to a predefined characteristic, and signals an exceptional state if the comparison indicates that the detected values deviate significantly from the characteristic.Type: GrantFiled: January 20, 2005Date of Patent: May 14, 2013Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventor: Hans-Wilhelm Klein

Patent number: 6949945Abstract: A method and a device are provided for measuring the temperature of windings of a drive motor, especially a three-phase motor, which is supplied by a converter with three controlled half bridges from a direct current intermediate circuit. The method, a corresponding device, and a control system offer more accurate results with less complicated circuit engineering. To this end, one current flux traversing at least one of the windings of the motor is measured by the converter while approximately knowing at least one cold resistance and other parameters of the motor. A temperature change of the windings is calculated from a change in the current flux based on a change of the temperature-dependent resistance.Type: GrantFiled: October 20, 2003Date of Patent: September 27, 2005Assignee: BSH Bosch und Siemens HausgeräteInventor: Hans-Wilhelm Klein

Publication number: 20040088334Abstract: A system and method for efficiently storing multiple versions of a data object in a database and generating a report to display a single version of a data object corresponding to any given time are provided. The data object is represented by a versioned data structure that includes a belief time field for storing a belief time corresponding to a version of the data object. A single version of the data object is retrieved by generating SQL code including a select clause for specifying the fields that are required for retrieving the data object and a where clause for specifying the version of the data object to be retrieved. A single foreign key is used to access multiple versions of the same data object.Type: ApplicationFiled: November 1, 2002Publication date: May 6, 2004Inventor: Ralph Wilhelm Klein

Patent number: 6684111Abstract: An apparatus for power failure identification in a programmable household appliance includes an electronic program control apparatus having a first device disposed upstream of the mains switch on the power supply system side and a second device disposed downstream from the mains switch on the appliance side for identifying an electrical variable of the external power supply system or of the supply system in the household appliance. The program control apparatus compares the signals produced by each of the devices from the electrical variables to decide whether the failure or the change in the electrical variable of the household appliance is due to a failure of the external power supply system, or due to the household appliance being switched off deliberately.Type: GrantFiled: March 11, 2002Date of Patent: January 27, 2004Assignee: BSH Bosch und Siemens Hausgeräte GmbHInventors: Hans-Wilhelm Klein, Lothar Übler, Horst Werkmann

Patent number: 6289962Abstract: An apparatus for pressing a pneumatic tire off a rim of a motor vehicle wheel comprises a pressing blade for removing the tire by pressing it off the rim. The pressing blade is mounted pivotably on a support structure of the machine in a substantially horizontal plane of pivotal movement. The apparatus includes a lift means for lifting the motor vehicle wheel in a standing position with its wheel axis into the horizontal plane of pivotal movement of the pressing blade.Type: GrantFiled: May 17, 2000Date of Patent: September 18, 2001Assignee: Snap-on Deutschland Holding GmbHInventor: Wilhelm Klein

Patent number: 5429333Abstract: A device for temporary attaching holding or fastening structure to a surface. The device includes a fixture traversed by vacuum passages, whose one side bears the holding or fastening structure and whose other side serves sealing purposes and is provided with a closed roll of compressible material.Type: GrantFiled: March 23, 1993Date of Patent: July 4, 1995Assignee: Wilhelm Klein GmbHInventor: Wilhelm Klein

Patent number: 4877463Abstract: To produce threaded steel tension members, steel is used with a C-content of 0.50 to 0.80%, preferably 0.75%, a Si-content of 0.20 to 0.50%, preferably 0.25%, and a Mn content of 0.30 to 0.80%, preferably 0.60%. Exiting from the rolling heat at the outlet side of the finishing stand after hot rolling, the tension member or rod is subjected to surface quenching by a cooling medium, preferably water, so that the steel in a rim zone R.sub.1 is transformed immediately and completely into martensite, while the heat content remaining in the core zone K.sub.1 does not effect a tempering of the martensite rim zone during the subsequent cooling beyond the range of the intermediate stage.Type: GrantFiled: June 7, 1988Date of Patent: October 31, 1989Assignee: Dyckerhoff & Widmann AktiengesellschaftInventors: Max Aicher, Dieter Jungwirth, Hans-Wilhelm Klein, Dieter Russwurm

Patent number: 4724346Abstract: A permanent magnet-excited rotor motor is disclosed wherein, a circuit board (6) mounted on a radial motor attachment flange (22) is arranged. The front and rear sides of the circuit board (6) are equipped with conductor strips. On the front side, Hall transducers (15) influenced by rotor magnets (81) in a speed dependent manner are mounted. A flat cable brought in from the outside is divided into a first cable portion (12), passed through from the front with supply and signal voltage lines for the Hall transducers (15), and into a second cable portion (13) passed through from the back to the front with winding feed lines for the stator coil winding ends (14), which are likewise passed through from the back to the front of the circuit board (6) and thus can be soldered to the freely accessible front side.Type: GrantFiled: September 11, 1986Date of Patent: February 9, 1988Assignee: Siemens AktiengesellschaftInventors: Hans-Wilhelm Klein, Ernst Grecksch, Helmut Schmidt

Patent number: 4511214Abstract: The invention relates to an exterior mirror for vehicles, with a mirror-housing which, in normal operation, is retained in a fixed location on the vehicle and which, in the event of a collision, can fold away, forwards or backwards, until it assumes at least an approximately flat position against the vehicle. Folding occurs about a pair of pivot-axes. A mirror-shell, carrying a reflector, is retained in the interior of the mirror-housing. An aerodynamically efficient fairing is provided on the leading side of the mirror-housing. In order to be able to design the fairing with a shape which is particularly aerodynamically efficient, namely with a shape which is particularly long in the direction in which the vehicle travels and which resembles a wedge, while nevertheless being able, on the other hand, to permit the mirror to fold away effectively and with little overhang, at least one separate pivot-axis is provided for the fairing of the mirror-housing.Type: GrantFiled: January 21, 1983Date of Patent: April 16, 1985Assignee: Daimler-Benz AktiengesellschaftInventors: Wilhelm Klein, Jorg Koske, Siegfried Herzog, Hans-Peter Jordan, Wilhelm Bauer, Max Bausch, Christian Grabner

Patent number: 4502759Abstract: The invention relates to a servo-controlled adjustable outside rear view mirror for vehicles, having a stationary mirror housing and a mirror shell which carries the reflector and is able to move therein. In the mirror housing there is provided an interchangeable drive unit for the vertical and horizontal adjustment of the reflector, said drive unit being affixed to the back of the mirror housing or of the mirror shell. The invention aims at providing a broad vibrationless bearing surface for the mirror shell. Furthermore, by means of a simple control switch the mirror shall be adjustable in the same manner about a geometrically defined horizontal and vertical axis. The invention also aims at providing a wedge-shaped convergent, aerodynamic mirror housing. For this purpose, the drive unit is coupled by means of a movable plate to the rear of the mirror shell which can turn on a vertical axis, but the swivel connection has torsional strength about the horizontal axis.Type: GrantFiled: February 10, 1983Date of Patent: March 5, 1985Assignee: Daimler-Benz AktiengesellschaftInventors: Siegfried Herzog, Hans-Peter Jordan, Henryk N/o/ lscher, Wilhelm Bauer, Christian Grabner, Wilhelm Klein, Rolf Kr/u/ gener, Max Bausch, Gerard N/u/ ssle
