Abstract: A device for detecting and displaying the rear and/or side traffic of a motor vehicle is to be improved upon such that the driver can safely and quickly detect the present traffic situation by way of the overall image shown, in particular when the direction of travel is changed. This is accomplished in that the device for detecting and displaying the rear and/or side view of a motor vehicle (1) comprises a first apparatus (3) for producing images of the optically detected rear view (A), one or more further apparatuses (2) for producing images of the optical side view (B,C) of the motor vehicle (1), a display apparatus (6) adapted to display images or image sections of the first and/or the further apparatuses (2, 3) in partial areas (T1, T2), and a control apparatus (5) adapted to select the images or image sections and to assign them to the partial areas (T1, T2).

Abstract: The invention relates to a motor having an inner motor compartment (18). A rotatable rotor (20) can be driven by applying a pressure medium to it, wherein the pressure medium expands in a working region (40) of the motor compartment (18). A brake element (22) for braking the rotor (20) is disposed axially adjacent thereto. The brake element (22) and the rotor (20) are axially displaceable in relation to one another and form a spring-loaded friction pair (48, 50). In order to be able to achieves a higher braking effect due to stronger springs (52), a pressure chamber (60) is provided, the extension of which in the cross-section thereof is larger than the cross-sectional extension of the motor compartment (18) in the working region (40). The pressure chamber (60) is delimited axially at least on one side by the brake element (22).

Abstract: A vane motor comprises a casing and a vane rotor being mounted in the casing. A friction brake device is arranged in the casing and it is intended for braking, stopping and releasing the vane rotor. At least one of the two end faces of the vane rotor is part of the brake device and forms a friction pair with a braking surface of a brake element of the brake device. The brake element is arranged next to the said end face of the vane rotor and is axially movable upon actuation of the friction brake device for braking, stopping and releasing the vane rotor.

Abstract: A device for turning an electric motor on and off implements an expedient instantaneous turn-on or turn-off switching operation in which contact bridges are released for closing or pushed open by means of a spring-operated over-center device. Pivoting elements are rotated by means of the switching slide via their articulated legs such that, when the dead-center position, which is located between the axes of the pivoting elements, is overcome, one pivoting element axis is shifted in a quick-action motion. As a result of the contact bridge control levers, which are provided in different angular positions on the respective pivoting elements, a sequential switching of two contact bridges can be implemented such that initially the first contact bridge and then the second contact bridge are released for closing under the action of the contact closing spring while for opening initially the second and then the first contact bridge may be pushed open in opposition to the contact closing spring.

Abstract: A device for switching an electric motor, particularly for braking an electrically operated tool, comprises change-over switches 19' and 20' for connecting and disconnecting the electric motor to and from an associated power source, for reversing the polarity of a field winding or armature winding of the electric motor, and for enabling and disabling an electric braking circuit for the electric motor, also an actuating member 21' for the change-over switches 19', 20', a movable contact 32', which is associated with each change-over switch and is movable between a fixed ON contact 30' and an OFF contact 30, which is spaced an arcproof distance from said ON contact, and a sliding guide 40', which is associated with at least one movable contact 32' and is adapted to guide said movable contact over at least part of its path of movement during the switching operation. The actuating member consists of a switching slider 21', which cooperates with a toggle lever 54.

Abstract: The spinal cannula 1 is provided with a grip part, which consists of transparent plastic and surrounds the rear end of the cannula in a substance-securing manner. A cerebrospinal fluid checking chamber, which tapers toward the rear end of the cannula and is visible from the outside, is located in it, and this cerebrospinal fluid checking chamber is joined on the rear side by a conical plug-type Luer bore for accommodating the Luer plug-type cone of a drug syringe in a positive-locking manner. On the outside, the grip part has, between two flange parts, at least two, radially recessed grip surfaces, which are arranged diametrically opposed to one another and symmetrically to a plane of symmetry located in the longitudinal axis, and between which the cerebrospinal fluid checking chamber is arranged. In addition, there is a stylet, which can be introduced into the cannula through the cerebrospinal fluid checking chamber.

Abstract: A movable, tubular-shaped contact element is displaceably guided in a partition wall subdividing the internal space of the gas-blast switch housing into an extinguishing chamber and an expansion chamber. During the cut-off stroke a current connection prevails by means of this contact element between both of the chambers or compartments. The contact element coacts with a stationary or fixed contact set having a rim of rated current contacts which, in the cut-on position, engage about the contact element. Further, there is provided a burn-off ring which is electrically connected with the contact element and has an electrically insulated, suspended intermediate electrode which, in the cut-on position, engages into the contact element or piece. The latter, during the cut-off stroke, initially comes out of engagement with the rated current contacts and first thereafter comes out of engagement with the intermediate electrode.

Abstract: A movable, substantially tubular-shaped contact element coacts with a fixed set of contacts which, in turn, possesses a rim of rated current contacts, a burn-off rim electrically connected with the rated current contacts, and an intermediate electrode arranged electrically insulated from the rated current contacts. In order to prevent, during the cut-off operation, commutation of the base point of the arc from the burn-off rim back to the contact surfaces of the rated current contacts, the burn-off rim is arranged within the rim of rated current contacts and inwardly offset with respect to their contact surfaces. In the cut-on position the burn-off rim surrounds a burn-off tip secured at the end of the movable contact element. The burn-off tip engages with the intermediate electrode. Between the contact surfaces of the rated current contacts and the burn-off rim there can be arranged an insert formed of a material which, in the presence of an arc, gives off a gas.

Abstract: The insulation nozzle of a puffer type breaker has flexible contact fingers disposed along the walls of the nozzle upstream of the gas flow path through the nozzle. The flexible contact fingers engage a hollow tubular stationary contact which extends through the nozzle orifice when the interrupter is closed. A central arcing contact is fixed to the flexible contact fingers within the nozzle and projects into the interior of the stationary tubular contact when the contacts are closed. A plurality of main finger contacts are connected to the stationary contact, and slidably engage an outer main movable contact sleeve fixed to the movable arcing contact and the insulation nozzle. The movable contact sleeve forms a bridging connection between the main terminals of the interrupter when the interrupter is closed. The main bridging contacts disengage before the interior contact fingers within the nozzle disengage the stationary contact tube so that the outer fingers do not interrupt power currents.
