Patent DE-4130581-A1 (DE)
Inventor: HARTMANN UWE
IPC: H04N3/26
Filed: 1991-09-13
Abstract: Circuit arrangement for generating a horizontal deflection frequency modulation voltage with a parabolic time cycle for the appropriate modulation of the focussing voltage in devices with a picture tube, especially television sets. As in prior art devices, the circuit arrangement has a transformer T3 having a primary winding 3a and a secondary winding 3b coupled thereto. According to the invention, the primary winding 3a is connected to a voltage H proportional to the horizontal deflection voltage and, furthermore, only a fraction  PHI Ú of the magnetic flux  PHI  established by the primary winding 3a is linked to the secondary winding 3b, while the predominating remainder PHI scatter of this flux is closed via a by-pass 4c, 5 in the transformer core 4 circumventing the secondary winding 3b. Thus the transformer has a high inductivity with little coupling between the primary and secondary windings and the high inductivity has the result that the input voltage at the primary winding, proportional to the horizontal deflection voltage, establishes a saw-toothed primary current therein so that a saw-toothed secondary current is also generated via the corresponding magnetic flux in the secondary winding which is fed into a capacitor C3 and produces the parabolic modulation voltage therein.

Discs are fitted within the roller (1), esp. at the edge zones, across the roller axis to give separate zones of increased suction. The shaft (6) with the paddles is at least partially hollow with openings, which can be closed at least partially by a sliding hollow cylinder within the hollow shaft (6), with an open or closed end surface. The shaft (6) with fixed paddles can slide axially, and a central opening is closed in an end position by a disc rotating with the roller mantle. ADVNATAGE - The system ensures that the vacuum applied by the pump is wholly used to act on the paper web round the roller, without any pressure difference loss or dissipation of the effect.

Title: Arrangement for taking samples in bodies of water
Inventor: DUNKER ERICH
IPC: G01N1/12
Filed: 1993-05-28
Abstract: When taking samples in the boundary region of bottom water and sediment with a core tube arrangement, it is particularly important to obtain undisturbed samples. The arrangement must furthermore be designed as compactly and simply as possible, in order to be convenient to handle and cost-effective. Particular effort should be made to reduce the time factor, in view of the enormously expensive ship times. The arrangement (1) according to the invention has a support frame (2) which is divided into two, only the upper support-frame part (3) being lowered with the tube. Size and weight are thereby considerably reduced. Furthermore, only the core tube (8) penetrates into the boundary region (33, 34, 35) and no progressive rotational (swirling) effect occurs. Additional forces are not required. The release mechanism, in the form of a lever (22) for closing the core tube (8), is particularly simply designed. Sampling of deep-sea ocean bottoms or lake bottoms by relatively large or small ships for oceanographic or limnological research; used on its own or in combination with other measuring devices. <IMAGE>

Title: Method for predictive current limiting in a solid-state railway current converter
Inventor: XIE JIAN DR ING
IPC: H02H7/122
Filed: 1993-09-08
Abstract: A method for predictive current limiting is proposed in order to ensure selectivity in line protection in railway current systems when using solid-state railway current converters. In this method, the solid-state railway current converter is operated with voltage and frequency control and supplies a transformer on the railway power supply network side, and its semiconductors are controlled via a pulse pattern generator to which nominal voltage values from periodically sampled characteristics are supplied. In the case of the method according to the invention, the converter current (iestimate) which is predicted to occur at the end of the respective sampling period (T) is in each case determined in advance at the start of each sampling period (T) and is compared with a maximum permissible value of the converter current (imax), the predetermined nominal voltage value (Unom) remaining unchanged if it is less than the maximum permissible converter current (imax) and, if this value is exceeded, a changed, reduced nominal voltage value (U'nom) being passed to the pulse pattern generator (4) in order to limit the current. <IMAGE>
