Patent number: 9265399Abstract: A dishwasher method and apparatus providing an algorithm varying the speed of the recirculation pump that recirculates washing liquor present in the washing compartment so as to assure quiet pump operation is disclosed. The speed of the recirculation pump is varied by a control device that carries out the washing cycle. A true-running monitoring unit checks the operation of the recirculation pump. During a fill phase of the washing cycle, an inlet valve is opened, the recirculation pump is switched on and the algorithm provides stepped variation of the recirculation speed using a default value step, a test step in which a true running check is performed, and a modification step in which the default value is modified in response to the result of the test step, for use in the next iteration of the algorithm.Type: GrantFiled: May 20, 2011Date of Patent: February 23, 2016Assignee: BSH Hausgeraete GmbHInventors: Markus Gram, Peter Schweier

Patent number: 8440942Abstract: A circuit arrangement is provided for protecting from overheating a heating element whose resistance value is a function of its temperature. The circuit arrangement includes a power supply, a switch, and a switch control circuit, a current sensor providing a signal proportional to the current flowing through the heating element, and a first scaling device whose output provides a signal proportional to the supply voltage of the heating element. An evaluation circuit compares the difference signal determined by a first detector having an output that provides a difference signal formed from the signals of the current sensor and the first scaling device with a reference signal and the switch control circuit can be switched from a conducting state when the switch control circuit is in a first state to a non-conducting state when the switch control circuit is in a second state.Type: GrantFiled: December 10, 2004Date of Patent: May 14, 2013Assignee: Bsh Bosch und Siemens Hausgeraete GmbHInventors: Manuel Otto, Peter Schweier, Martin Stickel, Franz-Josef Wagner

Patent number: 7464529Abstract: A process and an arrangement for re-starting a previously interrupted spinning process in a spinning arrangement is provided. The arrangement includes a drafting unit which can be shut down and also an airjet unit including a vacuum chamber. For the purpose of removing an initially inhomogeneous fiber stream, a staple fiber strand, delivered by the re-operating drafting unit, is temporarily suctioned as waste via a deflecting device after it has left the drafting unit. Only then, when a homogeneous fiber stream has formed, is the staple fiber strand joined with a thread which is transported through the airjet unit. The inhomogeneous fiber stream is removed with the aid of the low pressure in the vacuum chamber.Type: GrantFiled: July 30, 2004Date of Patent: December 16, 2008Assignee: Maschinenfabrik Rieter AGInventors: Gerd Stahlecker, Gernot Schaeffler, Peter Schweier

Publication number: 20080190089Abstract: An airjet spinning arrangement includes a fiber feed channel, which runs into a vortex chamber, and a fiber withdrawal channel, which exits out of the vortex chamber. The fiber withdrawal channel is arranged in a spindle-shaped component, which can be moved away from the fiber feed channel by a moving device. In order to clean the area of the entry opening of the thread withdrawal channel, a cleaning channel is provided, which is directed against the spindle-shaped component and is connected to a pressurized air source. The cleaning channel runs into a ring channel, which surrounds the spindle-shaped component. A first exit opening of this ring channel is designed so that it forms a ring opening surrounding the spindle-shaped component and is directed against the spindle shaped component when the spindle-shaped component is moved away from the fiber feed channel.Type: ApplicationFiled: September 7, 2005Publication date: August 14, 2008Inventors: Gerd Stahlecker, Gernot Schaeffler, Peter Schweier

Publication number: 20080123556Abstract: A method and a circuit carry out initialization/registration steps for a device, in particular a household appliance, which can be connected to a network. The first initialization/registration of the device is controlled by adding an initialization signal on the actuation of a mechanical circuit device and wherein an address clearly identifying the device in the network is allocated to the device for initialization/registration. In order to carry out the initialization/registration, a control state signal which corresponds to circuit state of circuit device is stored in a flag memory which is associated with the device after the first initialization/registration of the device; after stopping and then restarting the device in the network, the adjusting state of the circuit device is compared to the memory state of the flag memory which corresponds to a determined combination function.Type: ApplicationFiled: October 27, 2005Publication date: May 29, 2008Inventors: Peter Bosen, Peter Engl, Bernhard Kobl, Peter Schweier
