Patent number: 7219592Abstract: The invention concerns a valve arrangement for controlling a hydraulic drive, the supply to and the outflow from the hydraulic drive being separately controllable. It is endeavoured to realise separate controls of the speed and the hydraulic pressure of the hydraulic drive. For this purpose, a pump pipe is connected with a first control valve, the first control valve is connected through a pipe with a first working connection and a second working connection of the hydraulic drive, and the first working connection is connected with a second control valve and the second working connection is connected with a third control valve, the second control valve and the third control valve opening into a tank (T).Type: GrantFiled: August 31, 2004Date of Patent: May 22, 2007Assignee: Sauer-Danfoss ApSInventors: Brian Nielsen, Poul Erik Hansen, Torben Ole Andersen

Patent number: 7146228Abstract: The present invention concerns an electrode for establishing electrical contact with the skin. The electrode comprises an electrically conductive gel (12) covering a part of a first side of an electrically conductive layer (4) and an electrically conductive by-pass element (19). The by-pass element extends, on the second side of the electrically conductive layer, over the circumference of the gel on the first side and is in electrical contact with the second side of the electrically conductive layer at a point opposing an area covered with electrically conductive gel at the first side of the electrically conductive layer. The by-pass element ensures that the electrode continues to be operable even if exposed to chemical or mechanical stress.Type: GrantFiled: July 11, 2001Date of Patent: December 5, 2006Assignee: Medicotest A/SInventor: Brian Nielsen

Patent number: 7134380Abstract: The invention concerns a valve arrangement for controlling a hydraulic drive, the supply and the outflow of the hydraulic drive being separately controllable. It is endeavoured to improve the valve arrangement in such a manner that it is intrinsically tight, at the same time having a relatively simple design. For this purpose, a pump pipe and a tank pipe are connected with a first control valve, the first control valve being connected by separate pipes with a second control valve and a third control valve connected in parallel with the second control valve, the second control valve being connected with a first working connection of the hydraulic drive and the third control valve being connected with a second working connection of the hydraulic drive, backflow preventers for preventing the flow from the hydraulic drive in the direction of the tank being connected in parallel with the second control valve and/or the third control valve.Type: GrantFiled: August 31, 2004Date of Patent: November 14, 2006Assignee: Sauer-Danfoss ApSInventors: Brian Nielsen, Poul Erik Hansen, Torben Ole Andersen

Patent number: 7066446Abstract: A hydraulic valve arrangement with a first and a second working connection, both working connections being connectable with a hydraulic consumer, a supply connection having a pressure connection and a tank connection, a first valve, which closes the pressure connection or connects it in a controlled manner with the first working connection or the second working connection, a second valve, which closes the tank connection or connects it in a controlled manner with the first or the second working connection, and a control device, which controls the first valve and the second valve. It is endeavored to enable a simple manner of exact controlling the consumer. For this purpose, at least one valve is provided with an opening degree sensor, which is connected with the control device, the control device controlling the valve arrangement in dependence of the signal from the opening degree sensor and a specified signal.Type: GrantFiled: September 20, 2004Date of Patent: June 27, 2006Assignee: Sauer-Danfoss ApSInventor: Brian Nielsen
