Abstract: A hybrid pump (1) with a housing (2) comprising at least one suction port (10) and at least one pressure port (11). A rotor (5) is eccentrically arranged in the housing chamber (3) which is substantially enclosed in a circular manner. The rotor (5) has a plurality of circumferentially spaced vanes (6) which are radially arranged at least in some segments and are made of a material that is resiliently deformable under centrifugal force. The eccentricity (14) of the rotor (5) in relation to the housing chamber (3) and the elasticity of the rotor vane (6) are such that in a first phase of low rotational speed, the radially distant end areas (7) of each vane (6) touch only some or no circumferential segments (4) of the housing chamber (3) in the course of one rotor (5) rotation, whereas in a second phase of higher rotational speed, the radially distant end areas (7) of all vanes (6) touch the inner wall (4) of the housing chamber (3) essentially during the entire rotor (5) rotation.

Abstract: In a connector to be connected to a cable having a core wire, a retainer is fitted into a rear portion of an insulator holding a contact. The core wire is crimped by a wire crimping barrel formed to the contact. The cable is clamped in cooperation with the retainer and the insulator and extracted through the rear portion of the insulator. In addition, the contact has a locking barrel. On the other hand, the retainer includes a locking portion which is engaged with the locking barrel to prevent the contact from being released rearward from the insulator.

Abstract: A method and apparatus for drying book and similar paper-based materials in wet or frozen state, in which the material dried is exposed to microwave irradiation with frequency from 500 MHz to 10 GHz and in which the book or similar paper-based materials is lined with ceramic slabs before the drying. In this arrangement the materials are subsequently exposed to microwaves under atmospheric or reduced pressure. An apparatus for carrying out the method includes microwave drying oven modified for a batch or continuous operation, which includes adjustable ceramic slabs capable to absorb both moisture and microwaves.

Abstract: The invention describes a method of brazing workpieces (16) with a torch (10), in particular a plasma or welding torch, having an electrode (28), in which a transmitted and/or non-transmitted working arc supplied with power from a power source or a current source (2) is produced in order to generate a plasma beam from a delivered plasma gas, whereby at least one filler material (38) is fed to the seam region of the workpieces (16) to be joined. The filler material (38) is connected to the or to another power source or current source (39). To this end, one potential (40) of the power source or current source (39) is applied to the filler material (38) and the other potential (35, 41) to the workpieces (16). The power source or current source (39) is regulated in such a way that when the filler material (38) is lifted off the workpiece (16) an arc is prevented from being generated.

Abstract: The present invention relates to a high-speed controlling device, suitable for displacing a switching element between two positions with very short switching times. Said device comprises two switchable electromagnets, between which an armature, with a driven coupling to the switching element, is arranged. According to the invention, said armature contacts the first electromagnet in the first position of the switching element and contacts the other electromagnet in the second position of the switching element. In order to obtain particularly short switching times for the switching element, the armature can be firmly secured to a shaft, which is rotatably mounted about its longitudinal axis and to which said switching element is also fixed in an axially offset manner in relation to the armature.

Abstract: A camshaft adjuster for an internal combustion engine having hydraulic medium guides. The adjuster can include a setting unit that can be controlled by a control unit using these guides in the adjuster, wherein the setting unit is for adjusting an angle of a camshaft. This setting unit has an inner body coupled to the camshaft so as to rotate with it, and an outer body that is mounted to rotate relative to the camshaft via a drive connection which runs from a crankshaft to the camshaft. The camshaft has at least one insert part permanently inserted camshaft wherein these two components together form at least one hydraulic medium guide at least in partial regions over its axial length. This design is to create a camshaft adjuster which is in interaction with a camshaft having an insert part so that there is a simple and reliable supply of hydraulic medium to the camshaft adjuster and in particular to its control device.

Abstract: The invention relates to a belt band conveyor such as a curved belt conveyor having an endless transport belt that is guided over deflection rollers. There is a guide element that projects beyond the belt plane wherein this guide element can be handled separately before it is attached to the transport belt. This guide element moves along as the transport belt moves, and on whose guide surfaces, which extend in the transport direction of the transport belt has running surfaces that are inclined relative to the belt plane roll off from rotating guide rollers as the transport belt moves. Thus, lateral forces that occur crosswise to the transport direction of the transport belt can be compensated. A plurality of separate guide shoes are attached to the transport belt, forming a guide strip for the guide rollers that extends in the transport direction, circulates, and is divided into multiple parts.

Abstract: The invention relates to a reaction vessel (1) for producing a sample, in particular a crystal, from a substance in solution or in liquid form, having several reaction chambers (6) each forming a separate gas chamber, consisting of at least one housing part, and each reaction chamber (6) has a reservoir (7) and several reaction areas (8) co-operating therewith, connected to one another and to the reservoir (7) in order to exchange gas. The reservoirs and the reaction areas co-operating with them are disposed immediately adjacent to one another in rows, distributed in a predeterminable, identical manner, these rows running parallel with one another. Each row of reservoirs (7) therefore co-operates with at least one row of reaction areas (8).
