Title: Method for controlling a process
Inventor: SINDELAR RUDOLF DR ING
IPC: G05D23/20
Filed: 1993-09-03
Abstract: The invention relates to a method for controlling a process which can assume different power levels, has a different dynamic behaviour at these power levels, and which forms the control path (1) of a control loop with a state controller (2). In order to achieve optimum adaptation of the state controller (2), it is proposed to adapt control parameters (ri), that is to say the components of the control vector (r), as a function of the respective power level and in a different manner for each parameter (ri). In addition, it is proposed to link the adapted control parameters (ri) by multiplication, not using state variables but only using their change, that is to say using delta state variables ( DELTA xi). <IMAGE>
Patent DE-4336239-A1 (DE)
Inventor: RIEDER KLAUS-HARTWIG
IPC: H03L7/14
Filed: 1993-10-23
Abstract: To ensure interference-free transmission of digital messages, very high demands are made on the accuracy and stability of the clock generators. It is known to use for this purpose microprocessor-controlled digital phase-locked loops and to use for this expensive highly stable crystal oscillators. An accurate system clock should be delivered even if the reference clock fails. Contradictory demands are made on the phase-locked loops, on the one hand a wide bandwidth to achieve a small phase timing error and on the other hand a narrow bandwidth in order to keep down the influence of jitter and wander on the clock accuracy when the reference clock fails. It is the object of the invention to specify a circuit arrangement for an inexpensive clock generator which should deliver a highly accurate clock frequency even when the reference clock fails. According to the invention, the contradictory demands on a phase-locked loop are distributed over two phase-locked loops, both of which are controlled by a microprocessor and which are allocated only one oscillator. A first phase-locked loop (1) having a narrow bandwidth is connected via a change-over switch (3) to a second phase-locked loop having a wide bandwidth. When the reference clock fails, the output clock of the first phase-locked loop (1) is switched as reference clock to the second phase-locked loop (2). <IMAGE>

Inventor: TAYLOR JAMES RONALD
IPC: G01N33/18
Filed: 1994-03-29
Abstract: The conductivity system comprises a probe assembly 2 and operating circuitry 13. During normal operation of the probe assembly 2, control circuitry 14 applies an a.c. voltage to the probe tip 12 and the conductivity of water 12 in boiler 4 is monitored. During a cleaning operation, control of the probe assembly 2 is by cleaning circuitry 18 which applies a d.c. voltage to the probe tip 12. This has the effect of overcoming the problem of a build up of scale on the probe tip 12. The d.c. voltage is applied for periods of 30 - 300 seconds at intervals of 1 - 10 hours and produces a current of 100 - 500 mA. The frequency of the a.c. voltage may be 1 KHz. <IMAGE>

Patent DE-4423422-A1 (DE)
Inventor: BAUER FRANZ
IPC: B24B5/42
Filed: 1994-07-06
Abstract: In normal superfinishing based on an adjustable tool (5) and a rotating workpiece (1), a linear high-frequency reciprocating movement (6) extending parallel to the geometric axis (4) of the workpiece or of the journal is superimposed upon the rotational movement (3) of the latter. According to the invention, a linear low-frequency reciprocating movement (7) preferably extending over the entire length of the journal or the length of the rolling element is then superimposed upon this linear high-frequency reciprocating movement (6). This means that the treatment can be more intensive, e.g. at the ends of the journal or the like, thereby reducing the normal diameter found there in superfinishing. However, it is also conceivable to produce any other contour differing from a mathematically straight line. The process may also be applied to the formation of a curved generating line. Fig. 1b (not shown). The process is suitable for rolling elements, bearing journals and bearing races. <IMAGE>
