| 20080203849 | Energy Converting Apparatus, Generator and Heat Pump Provided Therewith and Method of Production Thereof - A high-efficiency thermionic energy converter comprises a multilayer vacuum diode, the layers of which are very thin and the intermediate spaces between the layers are several nanometres thick. The layers are held at a distance from each other by arranging insulator elements embedded in the layers. One of the intermediate spaces is provided with a thin, open conductive elastic foam plate which fills the spaces possibly occurring due to deformation of an upper electrode. On the cold side the distance between the layers must be so small that here the thermionically generated current is increased by tunneling of electrons from layer to layer. The partial efficiency per layer is as optimal as possible by means of the choice of the geometry and the material. For the purpose of pumping heat from for instance the thick electrode to the other thick electrode of the converter, or vice versa, in accordance with the Peltier effect, a current is conducted through the converter which is increased by tunneling of electrons. Cooling or heating takes place subject to the current direction. | 08-28-2008 |

The thermionic generator comprises a rαultilayered vacuum diode, the layers of which are very thin and the gaps between the layers are also thin and kept at a distance from one another by selectively flexible spacer elements. Piezo elements or heating elements can precisely adjust the height of the gaps. | 01-28-2010 |

| 20110114084 | HEAT RECOVERY INSTALLATION USING SOLAR ENERGY - A heat recovery installation using solar energy includes a three-channel plate, in which the first channel layer, viewed from the outside, alternately discharges used air and supplies fresh air. The third channel layer, viewed from the outside, ensures the supply of used air and the discharge of fresh air, while in the second channel layer, viewed from the outside, the heat exchange between the used and fresh air takes place according to the counterflow principle. In order to produce this flow, small apertures are provided in the second and third plates, viewed from the outside, of the three-channel plate, as a result of which the flow in the channel layer, viewed from the outside, is at right angles to the channel plate. By making the airflow quicker than the heat flow (Pe>>1), no heat can flow from the inside to the outside, except for a small loss flow through the partitions and through radiation and, conversely, mainly heat exchange of the used to fresh air according to the counterflow principle takes place with heat recovery. If the channel plate is made of transparent material and the inner plate is provided with a (sun)light absorber, then (sun)light which shines on the three-channel plate is also converted into heat and given off directly and indirectly to the fresh air. | 05-19-2011 |

| 20080221602 | Appliance for Water-Jet Surgery - An appliance for water-jet surgery is provided that includes a plurality of supply cylinder and piston arrangements in each of which is stored a working fluid that can be expelled, by means of the piston, through an outlet into a pressure conduit. At least one actuation device is provided to actuate the piston of each supply cylinder. By means of a change-over device to change the actuation from the piston of one supply cylinder to the piston of another supply cylinder, it is ensured that the working fluid can be expelled into the pressure conduit from consecutively emptying supply cylinders. As a result, an apparatus with a small structure that is achieved by simple means is disclosed. | 09-11-2008 |
| 20090023990 | PROBE MANIPULATOR - A probe manipulator which has a grip device that can be held by a user in order to facilitate manipulation of a probe when the latter has been inserted into a channel of an endoscope. Connection devices are provided for releasably connecting the grip device to the probe in such a way that the probe may be rotated or displaced by rotation or displacement of the grip device. The connection device is connectable such that the probe need not be fed through the grip device, but that the grip device may be placed at any point along the length of the probe. | 01-22-2009 |
| 20090060764 | Medical Pump - Medical pumps for water jet surgery are known. The invention relates to a pump comprising at least two pistons provided with piston rods for displacing the pistons in cylinders and for coupling to a pump actuation device, a cylinder head for closing the cylinders, and valve means for respectively connecting a pressure chamber in the cylinder to at least one fluid inlet and at least one fluid outlet. Said fluid outlet is connected to the fluid inlet in a communicating manner by means of an adjustable pressure regulating valve, in such a way that the pressure in the fluid outlet can be limited to a predetermined maximum value so that operation of the pump can be. | 03-05-2009 |
| 20090105695 | DEVICE FOR TREATMENT OF HUMAN OR ANIMAL TISSUE BY MEANS OF A MAGNETICALLY MOVABLE INSTRUMENT - A device for the treatment of human or animal tissue by means of a movable instrument is disclosed. The device comprises means for generating a magnetic stator field, in which the tissue is located. For example, the means for generating the magnetic stator field may be a magnetic resonance tomograph (MRT). At least one conductor loop is provided on or in the instrument, and a generator is provided for generating a current that flows through the conductor loop in order to generate a magnetic useful field, which, in conjunction with the stator field, generates a resulting action for applying a useful force to the instrument. | 04-23-2009 |

| 20110166568 | NEUTRAL ELECTRODE DEVICE, ELECTROSURGICAL INSTRUMENT COMPRISING A CORRESPONDING NEUTRAL ELECTRODE DEVICE, CONTACT MEDIUM, AND USE OF A LATENT HEAT ACCUMULATOR FOR COOLING AN ELECTRODE - In surgery using monopolar HF (high frequency), there is a constant risk of patients suffering burns at the neutral electrode. The problem stems from the fact that numerous methods have been devised by which relatively high HF currents are applied for extended periods of time. The present disclosure solves said problem by providing a neutral electrode device to be used for applying an HF current to a biological tissue. The improved neutral electrode device comprises at least one latent heat accumulator for absorbing heat. Thus, heat peaks can be at least temporarily accumulated until the accumulated thermal energy can be safely released. | 07-07-2011 |
