Publication number: 20020044622Abstract: An apparatus is described for catching and cooling a melt, in particular a core melt in a containment of a nuclear power plant. A porous body with which the melt comes into contact is provided. A pre-pressurized coolant is fed to the porous body so that the cavities in the porous body are filled with the coolant. After contact between the melt and the porous body, the pre-pressurized coolant penetrates into the melt and as a result leads to fragmentation, solidification and long-term cooling.Type: ApplicationFiled: May 29, 2001Publication date: April 18, 2002Inventors: Hans Alsmeyer, Dietmar Bittermann, Manfred Fischer

Publication number: 20010048880Abstract: The invention is based on a radial piston pump (1) with a pump body (2), in which pump body (2) are placed pistons (4), and cylinders (5) arrayed radial to a cam (14) and the pistons (4) upon an inward thrust suck in fluid by means of suction side intakes (17) and upon an outward thrust, the pistons (4) impel fluid through pressure openings (7) in the outer end walls (6) of the cylinder (5) into a plenum (10) whereby the check valves (22) are formed from an annular coil spring valve (9) which cover the pressure ports (7) and the thereto connected stress relieving corrugations (8), and upon the exceeding of a specified threshold transport pressure, the respective pressure opening (7) opens to the plenum (10). The proposal is made, that a stress relieving zone (27) of a piston-cylinder unit (4, 5) be connected to the pressure zone (5, 7, 26) of a neighboring piston-cylinder unit (4, 5).Type: ApplicationFiled: May 10, 2001Publication date: December 6, 2001Inventors: Michael Herrmann, Manfred Fischer

Publication number: 20010037786Abstract: A method for the manufacture of a cylinder liner for combustion engines and a cylinder liner which can be manufactured by the method according to the invention are disclosed. The method comprises a thermal spray-deposition, such as by an arc spray-deposition process, of a wearing layer on a supporting body and a spray-deposition of a protective or connecting layer on the wearing layer. The wearing layer comprises a hypereutectic aluminum-silicon alloy and the protective or connecting layer comprises a hypoeutectic aluminum-silicon alloy. A melt retarder of iron, for example, may be interposed between these two layers. The melt retarder comprises a higher melting temperature than the two aluminum-silicon alloys, thereby preventing the wearing layer from partially melting when the cylinder liner is cast into a cylinder bore.Type: ApplicationFiled: April 10, 2001Publication date: November 8, 2001Inventors: Manfred Fischer, Rudolf Mundl, Peter Godel, Wolfgang Reichle, Werner Trubenbach, Markus Muller, Reinhard Rosert

Patent number: 6224017Abstract: A brake for a flap adjusting mechanism and a method for condition monitoring are proposed. The brake has one or more temperature sensors (30). In the method for condition monitoring, the temperature signal is compared with a desired temperature (T1, T2) in the signal processing unit in a time period during or after a rotation of the driveshaft (2) in the housing (4) while expending the braking moment. An error signal is produced in case of deviations of the temperature signal from the desired temperature.Type: GrantFiled: April 28, 2000Date of Patent: May 1, 2001Assignee: Liebherr-Aerospace Lindenberg GmbHInventors: Manfred Fischer, Bernard Hunold, Karl Zimmermann

Patent number: 6192097Abstract: A retaining device has a multi-layer protective cladding for protecting the bearing and containment structure of a spreading chamber for the controlled spread and cooling of a melt from a nuclear reactor pressure vessel. The spreading chamber is configured under the spreading concept, i.e. the melt spreads and cools therein. The protective cladding has at least two layers: an outer sacrificial layer acts as a thermal shock barrier and melting substance; a protective and insulating layer, disposed inside the sacrificial layer and protecting the underlying bearing and containment structure, acts as thermal protection layer and retaining layer for the hot melt. The protective and insulating layer includes a first partial layer of fireproof concrete adjacent the bearing and containment structure, and a second partial layer of temperature-resistant ceramic blocks, in particular ZrO2 adjacent the sacrificial layer.Type: GrantFiled: May 22, 1996Date of Patent: February 20, 2001Assignee: Siemens AktiengesellschaftInventors: Gerhard Hau, Lothar Wistuba, Josef Hollmann, Manfred Fischer

Patent number: 5966997Abstract: A device for transmitting linear motion for adjustment of a wing element (4) is provided with one input part (23) and one output part (26) wherein between the input part (23) and the output part (26) an uncoupling mechanism is provided which, above a preset force (release force) makes relative motion between the input part and the output part possible. One or more prestressed springs (42), which can absorb energy during relative motion, upon unloading, restores the input and output parts to an initial position. A translation mechanism converts the relative motion between the input part (23) and the output part (26). The converted motion acts upon the spring (42) whereby a force-path characteristic line of the device, corresponding to the translation mechanism, can be obtained. The translation mechanism consists of a crankshaft (52) with cam discs (50A, 50B) driven by a connecting rod (46) which act upon a piston (48) longitudinally movable within the housing (30) and prestressed by springs (42).Type: GrantFiled: November 3, 1997Date of Patent: October 19, 1999Assignee: ZF Luftfahrttechnik GmbHInventors: Christian Halm, Manfred Fischer, Bernard Hunold

Patent number: 5907588Abstract: A device for collecting core melt from a reactor pressure vessel improves a flow of the core melt out of the reactor pressure vessel. A prechamber is disposed below the reactor pressure vessel and a spreading chamber for the core melt is disposed laterally next to the reactor pressure vessel. The spreading chamber is connected to the prechamber through a channel. A base unit forms a bottom region at least of the prechamber and is made of a material having high thermal conductivity.Type: GrantFiled: October 6, 1997Date of Patent: May 25, 1999Assignee: Siemens AktiengesellschaftInventors: Manfred Fischer, Dietmar Bittermann, Lothar Wistuba, Horst Weisshaupl

Patent number: 5839562Abstract: A linear drive for displacing a component, in particular an aircraft wing component, is provided with an input part (1) on the driving side and an output part (4) on the driven side, there being provided between input part (1) and output part (4) an uncoupling device which interrupts a force-locking or a form-locking connection between input part (1) and output part (4) when a predetermined force is exceeded. The input part (1) comprises a freewheel outer part (2) which is connected to the output part (4) via a freewheel inner part (3). Disposed between the freewheel outer part (2) and the freewheel inner part (3) is a tubular freewheel cage (5) with a plurality of pockets (6) which house clamping members (7A, 7B) prestressed by control springs (8) so that they can move in an axial direction. The pockets (6) are provided with inclined ramps (9A, 9B) extending in an axial direction. Spring assembly (10), generating an axial prestress, is disposed between the freewheel inner part (3) and the output part (4).Type: GrantFiled: July 3, 1997Date of Patent: November 24, 1998Assignee: ZF Friedrichshafen AGInventor: Manfred Fischer

Patent number: 5199538Abstract: A drive device with variable torque-limiting system. When a setting mechanism (17) forming part of a crank mechanism (23) is actuated in order to displace a carrier waggon (19) to which a hydrofoil component (2) is fastened, large forces are induced. To avoid excessive stresses on the components, the torque-limiter (15) is designed so that the drive torque is automatically variable within the limits of an adjustment range (88). The drive torque to be limited can, for example, be set at low values at the beginning and at the end of an oscillation path of the setting mechanism (17). The drive torque is varied by varying the preloading force of the spring assembly (47) of the torque-limiter (15). To this end, a comparator (74) detects the number of rotations of the output shaft (38) and varies the preloading force of the spring assembly (47).Type: GrantFiled: August 22, 1991Date of Patent: April 6, 1993Assignee: Zahnradfabrik Friedrichshafen AGInventors: Manfred Fischer, Alfred Magg
