Abstract: The invention relates to a system for monitoring and managing a point-to-multipoint access network to connect a line terminal (10.sub.1) to a plurality of network terminations (30). Each network termination (30) comprises facilities (31) for detecting transmission errors. For each error that is so detected, facilities (31) generate a word (m) which is representative of the detected error. Processing facilities (33) are provided in order to process the words generated by the detection facilities (31). In each network termination (30), there are simulation facilities (38) for generating simulated error words (ms) and facilities (32) for replacing for the errors which are detected by the detection facilities and by the simulated error words (ms) generated by the said simulation facilities. The point is to provide known signals which can be monitored in order to test the accuracy of the equipment.

Abstract: A method of generating an X-ray microbeam of the present invention generates an X-ray microbeam having a restricted divergence angle and desirable planeness in regions other than the focus. With this method, it is possible to compensate for a change in the degree of asymmetry ascriable to a change in the wavelength of X-rays selected, and therefore to maintain the degree of asymmetry constant. In addition, the condensing conditions including the energy of X-rays and beam size each can be set independently of the others. A device for practicing the above method is also disclosed.

Abstract: A slip controlled induction motor using a variable frequency feedback transducer comprises a motor stator, a motor rotor and a variable frequency feedback transducer (VFFT). The VFFT includes an input winding transformer coupled to an output winding by a VFFT rotor. The VFFT rotor is operably connected to the motor rotor so as to rotate with the motor rotor at the same angular velocity. The input winding is excited with an input AC voltage of predetermine frequency. The transformer coupling combines the predetermined frequency AC input with the signal produced by the VFFT rotor to produce a variable frequency signal in the output winding which is fed as an input to the motor stator. Since the stator input is tied to the motor rotor angular velocity, the stator input will always have a constant absolute frequency difference with the motor rotor.

At least one metering chamber is disposed downstream of each conveying chamber and is movable between a first position open towards the conveying chamber and a second position free from the conveying chamber. A metering piston is displaceably disposed in each metering chamber and partially releases the metering chamber in the latter's first position and empties the metering chamber in the latter's second position.
