Abstract: A method is disclosed for molecular imaging with the aid of a molecular probe, the latter containing a contrast enhancing component that is detectable via X-ray fluorescence radiation emitted thereby. A device contains an X-ray source for radiating with X-radiation an object provided with the molecular probe, as well as an X-ray receiver for receiving an X-ray fluorescence radiation emitted by the contrast enhancing component.

Abstract: The longitudinal guide for an automotive vehicle seat has two elongate rails, namely one bottom rail and one seat rail, and guide means in the form of roll and/or sliding bodies that are disposed between the rails. Each rail has, when viewed in profile, a) an L-shaped region formed by two L-legs and b) two end regions, each of which joins the L-shaped region and has multiple bends and against which the guide means are resting. The end regions of a rail are mutually interlocked to respectively form an encompassing region with a respective one of the end regions of the other rail. In each encompassing region when viewed in profile, two channels are respectively provided for guide means. Each encompassing region comprises a first channel having first confronting guide surfaces that extend substantially in the y-direction when viewed in the profile of the rails. Said guide surfaces fix the position of a guide means located between them in the z-direction but not in the y-direction.

Abstract: The invention relates to a device for forming connections of a printed circuit board which is arranged within a signal receiver frame. The device comprises a plurality of connection elements (3a . . . 3k) whose end portions are bent, each end portion being provided with at least one projection (5). Between each time two connection elements (3a . . . 3k) there is provided a respective detainer (4a . . . 4j) whose end portion is also bent. The end portions of the connection elements (3a . . . 3k) define a plane which extends parallel to a plane defined by the end portions of the detainers (4a . . . 4j).

Abstract: An X-ray diagnostic apparatus has at least one beam transmitter which emits an X-ray beam acquired by at least one solid-state detector with image points arranged in the form of a matrix, and at least one correction unit that acquires the image signals, produced by the solid-state detector, of the current bright image exposure of a subject to be examined, and acquires the any afterglow signals which may be present from at least one dark image exposure. The correction unit controls the beam transmitter dependent on the presence of afterglow signals and/or the intensity of the afterglow signals, and, if necessary, corrects the image signals of the current bright image exposure.

Abstract: A medical diagnostic installation has an MR apparatus and an X-ray exposure apparatus and allows MR exposures and X-ray exposures to be simultaneously produced. A common patient support is provided, so that a patient can be simultaneously charged with magnetic fields and transirradiated by X-rays. The generation of the X-ray images ensues with a solid-state detector.

Abstract: A vacuum plant, in particular for secondary metallurgy, having at least one ejector which is in communication with a closed container within which a metallurgical vessel which is to be placed under pressure can be brought. A second ejector is connected in series with the one ejector via an intermediate condenser having a cooling water feed line and a condensate discharge line. A final condenser and a suction pump are connected to the second ejector. A controllable condensate distributor member is provided in the condensate discharge line of the intermediate condenser. One line of the distributing member is connected to a heat exchanger and the other line is connected to the cooling water supply of a final condenser.

Abstract: The invention concerns a jet compressor for gaseous media for use in metallurgical or chemical processes having a driving nozzle which is arranged centrically in a jet head and directed toward a mixing chamber with which a diffuser is connected coaxially. In order to avoid the conventional disadvantages and provide a jet compressor which is simple in design and as compact as possible and to achieve improved efficiency and pressure ratios in comparison to jet devices of the same scale while operating in a reliable manner, it is proposed that the driving nozzle (10) be a ring jet nozzle having a conical central body (12) which narrows in diameter conically toward the mixing chamber (31) of the nozzle (30).

Abstract: An X-ray detector includes a scintillation crystal and a photosensor which is easily manipulated, easily positionable, and easy to contact to the scintillation crystal. The photosensor is arranged on a thin lamina having electrical contact surfaces. The lamina presses laterally against the scintillation crystal such that the photosensor covers the scintillation crystal, and the contact surfaces of the lamina are connected to corresponding contact surfaces on the scintillation crystal, or on a scintillation carrier.

Abstract: A radiation detector has a number of detector elements disposed following each other in the direction of incoming radiation propagation. The radiation detector is integrally constructed of a semiconductor body having spaced surfaces disposed substantially parallel to the radiation propagation direction. One of the surfaces has a p-conductive region immediately therebelow, and the other surface has an n-conductive region immediately therebelow. At least one of the surfaces is sub-divided by a region extending transversely to the radiation propagation direction which has a lower conductivity than the adjacent regions. This section divides the semiconductor body into different detector elements.

Abstract: An x-ray detector system has a detector element disposed at the end of a channel formed by spaced collimator plates. The thickness of each collimator plate projected onto the detector element increases along the length of the collimator plates in the direction of radiation propagation through the channel. The projection (and thus the thickness) has a greatest value at a detector-proximate end of the plate. The edge regions of the detector element are thus shielded from x-radiation by the extended width collimator plates. The length of the absorption paths in the detector element thus are substantially the same, even given a detector element which is slightly obliquely disposed. Thus the shape of the portion of the detector surface effective for detecting radiation is substantially independent of slight changes in the focus position.

Abstract: A hydraulic proportional action valve apparatus includes a throttle valve, and a pressure balance which permits adjustment of the pressure difference between a supply pressure and a consumer pressure. The pressure balance, which may be provided with a spring, is hydraulically supported. A supporting assembly, which is provided for this purpose, is biased by a constantly controllable pressure-regulating valve. The control of the pressure-regulating valve may occur as a function of hydraulic parameter, such as, for example, the load pressure or the pilot pressure of the throttle valve.
