Patent DE-19842624-A1 (DE)
Title: Operating method for vehicle steering system that can be used in normal or emergency operating mode
Inventor: BOHNER HUBERT
IPC: B62D5/06
Filed: 1998-09-17
Abstract: The system can be switched between a steer-by-wire level assigned to the normal mode, where the steering wheel (3) is connected to the steered wheels (6) via an electric or electronic system, and a fall-back level assigned to the emergency mode, where the steering wheel is positively coupled mechanically and/or hydraulically to the steered wheels. The fall-back level is activated in the normal mode if the steered wheels are displaced into the region of steering stop. When the fall-back level is activated it is either used in unison with the steer-by-wire level or is used instead of the steer-by-wire level, with the fall-back level being deactivated as soon as the steering handle is no longer actuated or as soon as the steering handle is actuated in a direction which takes the steered wheels away from the steering stop. The steering system may include a variable-angle transmission system, so that the movement of the steered wheels brought about by the actuation of the steering wheel depends on at least one vehicle parameter, when in the steer-by-wire level and during the activation of the fall-back level in normal mode a manual torque actuator (27), which is otherwise used to simulate the steering side forces acting on the steered vehicle wheels, is unactuated or its moment or power consumption reduced.

Title: Frequency divider circuit for frequency synthesizer
Inventor: CYRUSIAN SASAN
IPC: H03K5/00
Filed: 1998-09-30
Abstract: The circuit arrangement divides the frequency of an input signal through a factor of the form n-k/X, in which n and X are natural numbers and k is an integer. A frequency divider arrangement (12) receives an intermediate signal and generates an output signal with a frequency that is 1/n times the frequency of the intermediate signal. A multiplexer circuit (40) includes at least X inputs and an output connected to the frequency divider arrangement, in which an i-th input, with i= 0 to X-1, receives the input signal with a respective phase shift of 2*i*pi/n. A control logic (60) selects one of the inputs provided on the output and the X inputs of the multiplexer circuit, to produce the intermediate signal in such way, that the phase of the selected input at the end of n periods of the input signal comprises a shift of 2*k*pi/X with respect to the selected input at the beginning of these n periods.

Inventor: BADURA EUGEN
IPC: G01T1/29
Filed: 1999-02-19
Abstract: The invention relates to a method of operating an ion beam therapy system comprising a raster scanning device mounted in a beam steering system (6, 8) and presenting vertical deflection means (13) and horizontal deflection means (14) for the vertical and horizontal deflection of a treatment beam (11) perpendicular to the direction of said beam so that the treatment beam (11) is deflected by the raster scanning device on to an isocentre (10) of the irradiation site and scans a defined area surrounding said isocentre (10). To check the operational stability and operating safety of the therapy system the invention provides for the position of the treatment beam (11) in the area of the isocentre (10) to be monitored and evaluated. Operation of the ion beam therapy system is interrupted if the evaluation of the beam position indicates a deviation from a defined setpoint and said deviation exceeds a defined tolerance limit relating to a required half width of the beam profile. The tolerance limit is notably +/- 25 % of the required half width.

Patent DE-19919035-A1 (DE)
Inventor: WEIGOLD THOMAS
IPC: H02P6/08
Filed: 1999-04-27
Abstract: The invention relates to an electronically commutatable motor whose excitation windings of the stator can be connected to a supply direct voltage in order to generate a rotary field for the permanent magnet rotor with a commutation frequency and which can be separated from said supply direct voltage. The excitation windings can be switched via semiconductor output stages which can be controlled by control signals having the commutation frequency of a control unit and whose operating conditions change according to a predetermined or predeterminable specified value. The disadvantages of motors having pulse-width modulated control of the excitation windings can be avoided by using a simplified motor control. To this end, the supply direct voltage is fed to a direct current converter whose output voltage for the semiconductor output stages with the excitation windings changes according to the specified value, and such that, independent of the specified value, the control unit fully controls the semiconductor output stages with non-clocked control signals having the commutation frequency.

Title: Polder sludge draining process renders lagoon fit for agricultural use and water fit for release at low cost
Inventor: SCHARF EVA-MARIA
IPC: B01D21/00
Filed: 1999-07-06
Abstract: A process de-waters sludge from standing waters especially lagoons. The lagoon sludge is sub-divided into a higher rinse polder zone and a lower rinse polder zone, allowing water to drain steadily from high to low on a quasi-continuous basis, and the steady removal of sludge. Each rinse polder is preferably 10 times longer than its width and has a gradient of preferably 0.5%. Water discharged from the rinse polder is admitted to the lower basin containing especially growing reeds which act as a biological filter. Before final release, treated water is subjected to the natural self-cleaning action of a waterway. Residual water is removed from sludge by wholly or partly covering the sludge with a material having strong suction properties. The suction material may be raised at one end by a post to form a 'sail', allowing the wind and sun to remove the water vapor which rises by capillary action.
