Abstract: A blade wheel consisting of sheet metal for use in motor vehicle refrigerant pumps has blades that are cut out of a disk and pitched and base disk segments that lie adjacent to the blades and remain between the latter. The blade wheel is formed by at least two different blade wheel elements which are provided with cut out, pitched blades, are interconnected in a fixed manner and are arranged so that their respective base disk segments are offset in relation to one another, forming a gap therebetween, the elements thus forming a common bottom disk. A hub sleeve is provided in the center of one of these blade wheel elements (the hub disk), and the center of the other blade wheel element or elements (the bore disk or disks) is provided with a hub sleeve receiving bore, which can be pushed onto the casing of the hub sleeve.

Abstract: The invention relates to a rotary pump (1) including a rotor (3) arranged in a closed pump housing (2) which is in operative connection with a drive (5) for the pumping of a fluid (4), wherein an inlet opening (6) is provided at the pump housing (2) for the intake of the fluid (4) into the pump housing (2) and an outlet opening (7) is provided at the pump housing (2) for conveying the fluid (4) out of the pump housing into a storage container (8) which is at least partially filled with the fluid (4). In accordance with the invention the outlet opening (7) is arranged and designed at the pump housing in such a way that the fluid (4) can be conveyed out of the pump housing (2) through the outlet opening (7) to the storage container (8) directly and free of ducting. The invention further relates to a hydrodynamic mixer (100) with a rotary pump (1) in accordance with the invention and also to the use of the rotary pump (1) and of the hydrodynamic mixer (100) for the processing of a fluid (4).

Abstract: The invention relates to a blade wheel consisting of sheet metal for use in motor vehicle refrigerant pumps. The aim of the invention is to develop a novel blade wheel consisting of sheet metal for use in motor vehicle refrigerant pumps which, aside from a plurality of blades, also has a high blade height, thus ensuring a high throughput. Moreover, it also has smooth running properties without re-machining and, furthermore, also without re-machining, ensures an optimum sealing gap with respect to the housing. At the same time, it can always be produced simply and cost-effectively with an open construction (without an end plate) as well as with a closed construction (with an end plate). In addition, it is characterized by a high pumping efficiency. The inventive blade wheel (1) consisting of sheet metal for use in motor vehicle refrigerant pumps has blades (3) that are cut out of a disk and pitched and base disk segments (4) that lie adjacent to the blades (3) and remain between the latter (3).

Abstract: The invention is directed to a delivery system for delivering a medical device. The delivery system includes an inner member having a proximal end and a distal end. The inner member defines a longitudinal axis between the proximal end and the distal end. A tip is formed at the distal end of the inner member. A bumper is freely disposed on the inner member. The bumper has a proximal end and a distal end. A seat is defined between the tip and the distal end of the bumper. Additionally, a sheath is disposed about the inner member, the sheath having a proximal end and a distal end. The sheath is movable from a first sheath position substantially covering the seat, and a second sheath position axially offset to expose the seat. The invention also includes a handle in contact with the proximal end of the inner member.

Abstract: An ellipsometer measurement apparatus for determining the thickness of a film applied on a substrate, is described. The apparatus includes a light source emitting an incoming beam, a transmitting optical system conveying the polarized incoming beam to an incidence point on the substrate, and a receiving optical system that has an analyzer and conveys the reflected beam formed at the incidence point to a photodetector device, the polarization direction of the incoming beam and of the analyzer being modified in time relative to one another, and the intensity changes produced thereby being evaluated by way of an evaluation device in order to determine the film thickness.

Abstract: In the method for the determination of the pressure (p) in and/or of the through-flow (Q) of a liquid through a pump having at least one magnetic bearing for the axial journaling of the pump rotor (1), axial forces act on the rotor (1) of the pump during operation. The axial forces which act on the rotor are utilised for the determination of the pressure (p) and/or of the through-flow (Q).

Abstract: An apparatus is proposed for producing a plasma polymer protective layer on workpieces, in particular headlamp reflectors (10), which has a coating chamber (18) into which a polymerizable monomer can be introduced and in which microwaves produce, in the region of the magnetic field of permanent magnets, a plasma for depositing the polymer protective layer on the workpieces held on the workpiece carriers (11). The permanent magnets are arranged on the workpiece carriers (11). Furthermore, there is provided a transport device (12) which conveys the workpiece carriers (11) through the coating chamber (18), which transport device possesses a return line, having a cleaning station (22), for the workpiece carriers (11) outside the coating chamber (18) for returning the workpiece carriers (11) from the exit to the entrance of the coating chamber. By this means, the known ECR coating process can, with continuous cleaning of the magnets, be used in an in-line process.
