An output module that digitally outputs the code word over a data channel and a conversion device that converts the first analog signal and the second analog signal into multi-digit amplitude-proportional code words, wherein the code words are also available at the output module for outputting on the data channel and is digitally transmitted by the output module over the data channel.

The invention relates to a directional antenna mechanism of a mobile radio tracking receiver, comprising four antenna elements (12), which are fastened by a pivot pin (14) to the body (10) of the radio tracking receiver. For the duration of the use, the antenna elements are turned to an operating position, in which they are pointed away from the body. After use, the antenna elements can be turned to a transport position, in which the antenna elements are placed inside the body in the direction of the longitudinal axis of the body. In the invention, at least two antenna elements are connected to each other by a mechanism in a way that moving the first antenna element to the operating position or the transport position also causes the second antenna element to move to the same position simultaneously. Preferably, all the antenna elements are connected to each other by a mechanism in a way that moving one antenna element to the operating position or the transport position causes all the antenna elements to move to a corresponding position simultaneously. The mechanism according to the invention comprises a movable transmission rod (16) arranged inside the body, with toothings (26) and toothed discs (22) fastened to the ends of the antenna elements, contacting to the toothings of the transmission rod. The transmission rod is moved either manually by a lever (28) fastened to the transmission rod or by an actuator, such as an electric motor, arranged inside the body.

By attaching the cover member (33) to the end surface of the housing (3) so as to close the opening, all the brake support shaft (60), the clutch shaft (26) and the PTO shaft (29) supported by the cover member (33) are installed in the housing (3).

A device that may be applied in particular to shutters and similar and that will allow, by means of the rotation of the sole handle (28), the opening of the shutter, the orientation of movable blades (6) and the determination of the blocking in a plurality of different positions by moving rods (18) with the possibility of different interposition of metal plates (55, 56, 63, 66, 66 min ). In variants, i.e. the case of shutters with fix blades (6), the same handle (28) may be used for the sole opening of the shutter, while in the case of fix shutters with movable blades (6) said handle (28) may be used for the sole orientation of blades.

A motor vehicle power train control device capable of furnishing set signals of torque applied to wheels of the motor vehicle. The control device includes a mechanism to generate a signal representing a limitation of variation in speed of a heat engine integrated in a power train capable of reducing variations that are disturbing with regard to acoustics of the power train, and includes a mechanism to determine an operating point of the power train in an optimal operating range according to the signal that represents limitation of speed. The mechanism for generating the signal that represents a limitation of variation in the speed of the heat engine integrated in the power train is furnished, at an input, by parameters that represent characteristics of the motor vehicle and by parameters that represent the driver's wishes.

The conveyor has a driver, a useful mass and a counter mass which can be brought into a mutually oppositely oscillating rotational vibrating movement about a central axis of rotation by the driver. The useful mass and the counter mass are mounted so that they can be moved with respect to one another over spring arrangements which are distributed about an axis of rotation. A portion of the useful mass is a pot which is located detachably and exchangeable. The moments of inertia of the useful mass and of the counter mass are in a defined ratio to one another. The pot, which can be mounted exchangeably, is designed so that the moment of inertia of the useful mass and, with that, the ratio of the moments of inertia remain essentially unchanged. The moments of inertia are identical or that the moment of inertia of the useful mass is larger than that of the counter mass.
