Abstract: A process chamber of an installation for the thermal treatment of printed circuit boards is described. The process chamber may include a fan wheel supported on a shaft parallel to the printed circuit boards, the fan wheel being disposed between two walls of the process chamber. The fan wheel is open at its two end faces and the two end faces are at such a distance from the walls of the process chamber that gas flows in unimpeded in two substreams between the end faces of the fan wheel and the walls and flows out from the cylindrical surface of the fan wheel over the length thereof and in the extent of the process chamber in the form of a ribbon-shaped gas stream, the gas stream being directed essentially in the cross section through a channel onto the printed circuit boards.

Abstract: The invention relates to a supporting device of the transport device of a soldering apparatus for the conveying of printed-circuit boards with at least two revolving, endless transport chains, said transport chains running in guide rails in the transport zone and each passing through two guide elements at the ends of the transport zone, wherein, for adaptation to the width of the respective printed-circuit boards, the guide elements are mounted on a carrier such as to be displaccable transverse to the conveying direction. The guide elements, each associated with a respective conveying chain, are interconnected by flexible tension elements, said tension elements being adjustable with regard to their tensile stress and running parallel to the respective conveying chain in the transport zone, the value of the tensile stress being so highly adjusted that the tension elements prevent the guide rails from deviating from a straight line.

Abstract: In a magnetic resonance tomograph having a continuous channel for inserting from one end a stretcher with a female patient lying thereon in a prone position during magnetic resonance mammography, the tomograph is provided with a manipulator by which instruments for the diagnosis and surgical treatment of such patients breasts can be introduced into the channel from the other end and positioned in relation to the breasts which are disposed in the isocenter of the magnetic resonance tomograph. The manipulator has a support arm with a recess for receiving the various instruments which can be installed and exchanged from the other, that is, the proximal end. The support arm with the recess can be pivoted horizontally and vertically about a fixed point located outside the recess and beyond the tip at the distal end of the manipulator adjacent to a breast of the patient.

Abstract: An apparatus for the temperature regulation processing of electronic components such as semiconductor circuits, printed circuit boards and the like comprises a temperature regulated housing through which the components are conveyed on carriers. The carriers enter through an inlet slot in the housing provided with temperature regulating members and are conveyed onto a magazine and then out through an outlet slot opposite the inlet slot once processing is complete. Inside the housing, the carriers are loaded on a progressively loaded magazine provided with adjacently arranged holders. Once all the holders are loaded, the magazine is filled and in an end position. The magazine is then displaced to its starting position in a fast reverse run. A new carrier is conveyed in through the inlet slot thereby causing the temperature regulated carrier occupying the holder to be conveyed out through the outlet slot.

Abstract: In a stair-climbing vehicle for negotiating steps, ledges and stairs comprising a vehicle body having wheel support arms mounted thereon at opposite sides and in spaced relationship so as to be pivotable about a wheel support arm shaft and wheels rotatably mounted on the free ends of the wheel support arms, climbing arms are supported on the vehicle pivotable about the pivot axes of the support arms. The climbing arms are linearly extendable for moving the wheels from one step to the next, one wheel, one wheel support arm and one climbing arm forming together a stair climbing module.

Abstract: The invention relates to a method for the temperature regulation of components, for example semiconductor circuits, printed circuit boards and the like, in which the components are conveyed on carriers through an inlet slot into a temperature-regulating housing provided with temperature-regulating members and are conveyed out through an outlet slot opposite the inlet slot. The carriers are accommodated by a magazine in the housing, which magazine is provided with adjacently arranged holders and, after the first holder has been loaded, is displaced progressively in one direction from a starting position into successive accommodating positions in which the individual holders of the magazine are loaded one after the other.

In the housing, the carriers are loaded on a magazine provided with adjacently arranged holders. After the first holder is loaded in the starting position, the magazine is displaced progressively in one direction into successive positions in which the remaining holders of the magazine are loaded one after the other. Once all the holders are loaded, the magazine is filled and in an end position. Thereupon the magazine is displaced back to its starting position in a fast reverse run in the opposite direction.

Abstract: In an apparatus for guiding a medical probe into body cavities, a handle housing is provided consisting of inner, upper and lower modules. The inner module comprises a rinsing liquid supply and suctioning hose assembly, which can be removed and discarded after use. The lower housing part includes probe support and guide structures and the upper housing part includes operating slide members engaging the hoses of the hose assembly for controlling the flow through the hoses. It also includes means extending through the inner module and engaging the probe support in the lower module for axially moving the probe support and the probe retained therein. A two-lumina shaft extends from the apparatus in alignment with the probe and receives the probe, and flow communication structures are provided for interconnecting the two hoses with the lumina in the shaft.
