摘要:
A core barrel for a reactor pressure vessel of a nuclear reactor plant has a carrying structure that is supported on an inner surface of the shroud of the barrel. The carrying structure receives a tension rod that extends parallel to the longitudinal axis of the barrel and braces the shroud in the axial direction.

A supporting arm of a passenger door of an aircraft, has a curved structure which forms hollow chambers and movably connects the passenger door to a frame on the fuselage. Receiving means one for the supporting arm for receiving connecting means which enable a movable connection on the one hand to the passenger door and a pivoting drive and on the other hand to the frame on the fuselage, so that the door is movable by means of the supporting arm on a linear-displacement path and a pivoting path. The structure of the supporting arm is formed from fiber composite, the structure-forming fiber composite being formed from individual structural elements. This fiber composite structure further improves the thermal insulation of the supporting arm and nevertheless achieves a further weight reduction of the supporting arm, while maintaining exacting structural safety requirements for the latter.

According to the invention, the electronically regulated brake system additionally includes at least one pressure regulating valve (B) and/or at least one pressure regulating module (C).
摘要:
A method for stabilizing a vehicle in particular to prevent overturning, in which a strategy is selected from at least two different strategies as a function of a quantity describing or corresponding to whether an overturn tendency about a vehicle axis oriented in the longitudinal direction of the vehicle exists, and which may be determined at least as a function of a quantity describing or corresponding to the wheel behavior of at least one wheel, and which may also be determined a function of a comparison which is carried out as a function of a quantity describing or corresponding to the lateral dynamics of the vehicle and of a characteristic value that is determined as a function of a quantity describing or corresponding to the instantaneous friction conditions.

An internal-to-vehicle mechanism for monitoring the air pressure of a tire of a vehicle includes a sensor, detecting the tire pressure, which rotates, together with an electrotechnical first device, synchronously with the wheel and which, as a function of the tire air pressure that is determined, modifies parameters of the first device, namely the energy uptake of the first device. A stationary electrotechnical second device radiates an electric and/or magnetic, in particular electromagnetic, field through which the first device passes at, preferably, each wheel rotation with an uptake of energy from the field. A monitoring device detects the energy uptake and/or energy release of the second device.
摘要:
A steering device for vehicles having a pair of wheels which can be steered freely as a function of the current driving state of the vehicle or whose steered position can be locked by an electronically actuable locking device, having an electronic control device and having sensors which are connected to the electronic control device and have the purpose of monitoring current driving state values, with the electronic control device actuating the locking device when a minimum velocity of the vehicle is exceeded, in such a way that the steered position of the pair of wheels is locked, characterized in that driving state values which characterize critical driving situations are additionally stored in the electronic control device, in which the steered position of the pair of wheels is locked in critical driving situations, and in which, after a critical driving situation, the locking device does not release the pair of wheels again until predefined critical driving state values are undershot at least for a predefined period of time.
摘要:
A method for recognizing a trailer or semitrailer of a motor vehicle which includes activating at least one brake light of the trailer or semitrailer, independently of the driver, measuring a current flowing in a line assigned to the brake light of the trailer or semitrailer and ascertaining the presence or the absence of a trailer or semitrailer on the basis of the measured current.

Core shrouds are conventionally welded together from cylindrical parts and annular flanges, wherein cracks have recently occurred in the region of weld seams in reactors of the boiling-water type. A core shroud, in particular for cladding a reactor core in a boiling-water nuclear reactor and a method for repairing a core shroud, include recesses disposed transversely relative to the circumferentially extending weld seams. The recesses have a middle part which passes through a region that is thermally influenced during welding as well as transverse grooves or widenings located in front of ends of the middle part and lying outside the thermally influenced region. A clamp which is fitted into the recess is disposed approximately flush with a shroud surface and is wedged in one of the transverse grooves.

An apparatus for transporting and inverting core frame parts of a nuclear reactor includes a cross beam. A horizontal shaft is supported on the cross beam. A flexion and torsion-resistant basket is disposed below the cross beam for receiving a core frame part. A bearing pivotably supports the basket on the horizontal shaft. Pulleys are attached to opposite sides of the basket at right angles relative to the shaft. Positioning drives are seated at the cross beam and deflection rollers are adjustably attached to the positioning drives. Flexible tension members each lead from a respective one of the pulleys to a respective one of the positioning drives and to a respective one of the deflection rollers. The tension members are prestressed relative to the bearing for the basket.
摘要:
A device for the preparation of a gas mixture includes a closed circuit. Mixture components of a gas mixture are fed with greatly differing partial pressures ranging from low to highest partial pressures to the closed circuit. The gas mixture is circulated in the closed circuit. At least one of the mixture components with low partial pressure is replenished at increasingly shorter intervals. The gas mixture is completely exchanged when a given minimal length of the intervals is reached. At least one branch parallel to a section of the closed circuit conducts the gas mixture substantially completely free of flow losses. The at least one branch includes a magnetic valve, a differential pressure sensor in series with the magnetic valve having a total measuring range corresponding to the low partial pressures, the differential pressure sensor controlling the replenishment of the mixture components having the low partial pressure exclusively while the magnetic valve is closed, and an absolute pressure sensor controlling at least the replenishment of the mixture component having the highest partial pressure.
