Abstract: The invention concerns a feedback control method for controlling the starting of a steam turbine unit comprising a reheater, a turbine by-pass system consisting of a HP-by-pass system and a LP-by-pass system, at least one regulating valve for the HP-by-pass system, at least one regulating valve for the LP-by-pass system, at least one inlet valve for the HP-turbine, at least one intercept valve for the MP/LP-turbine and a governing device to regulate the turbine speed or power output, according to which method during no-load and low-load operation and up to a predetermined partial load the pressure within the reheater is regulated by a first feedback control device with the LP-by-pass regulating valve acting as positioning element in such manner that a greater quantity of steam will flow through the HP-turbine than through the MP-turbine, and a smaller quantity of steam through the HP-by-pass system than through the LP-by-pass system, whereby a maximum permissible HP-exhaust steam temperature will not be exceeded, and when the partial load is greater than said predetermined value the pressure within the reheater is regulated by a second feedback control device with the intercept valves acting as positioning elements until the intercept valves are fully open, while the LP-by-pass regulating valve is closed during this part of the operation. The invention also concerns an apparatus for the practical application of the method.

Abstract: A servo-motor control system having a load that is supported by a gear ring. The gear ring and the associated load are rotated by a driving wheel that is connected to the shaft of a servo motor. At least one transmitter rotatably contacts the gear ring at a point substantially 90 DEG  from the point of contact of the driving wheel. As the gear ring rotates, the transmitter generates a control signal that corresponds to the angle of rotation of the gear ring and includes a backlash signal component corresponding to either the magnitude or speed of the backlash and/or resilience of the servo system. A measuring means rotatably contacts the shaft of the servo motor and generates a servo operating signal corresponding to the operational angle of rotation of the servo motor. The control signal and the servo operating signal are combined by an adder to generate a difference output signal having a component corresponding to the negative backlash signal component. A position sensing gyro generates a signal corresponding to the movement of the load and the gyro signal includes a component corresponding to the backlash signal component. The gyro signal and the difference output signal are added to generate a feedback output signal from which the backlash signal component has been eliminated. The feedback signal is applied to control the operation of the servo motor.

Abstract: An automatically-adjusting photometer for measuring the absorbance of a sample in which the amount of light passing through a sample test location is sensed by a photodetector and converted to an electrical output signal. The output signal is amplified and converted to a logarithmic value. Prior to measuring the absorbance of a sample, the photometer is calibrated by a computer. With the sample test location empty, the computer records and places in memory a logarithmic value proportional to the electrical output signal which corresponds to zero absorbance. Next, this value is reduced by a predetermined factor by switching a resistor into the calibration circuitry. The resulting value is also recorded and placed in memory by the computer. When a sample is placed in the test location, the computer records a value proportional to the electrical output signal which corresponds to the absorbance of the sample. Using the three recorded values the computer calculates the correctly-adjusted absorbance of the sample.

Abstract: The invention relates to a toothbrush having a gripping part, with what is in the main a round profile, and having a front part, as brush head with bristle strands, which adjoins this gripping part. The object of the invention is to produce a toothbrush which, due to its ergometric design and shape, contributes to facilitating the brushing movements and to enabling regular manoeuvring, in order, thereby, to decrease the strength in the movements and the grip around the brush such that, using a controlled brush pressure, the brushing time can be extended. The object is achieved by means of a combination of the following features: a) the brush head, which is rounded on the rear side, extends from a bend at an angle of between approx. 25 degrees and approx. 35 degrees in relation to the longitudinal axis of the gripping part; b) the shaft-like gripping part tapers from the bend in the direction towards the end which is turned away from the bush head; c) in the bend, the gripping part tapers conically in the direction towards the brush head with the formation of an indentation on the rear side; d) the bristle strands extend from the front part of the brush head towards the free end of the gripping part over an area which is less than half of the length of the brush head. <IMAGE>

Abstract: A rotary pressure applying roll which defines with a parallel complementary roll a nip for a running web of paper, textile or other flexible sheet material in a calender or the like has a cylindrical shell surrounding a stationary carrier in the form of a rigid shaft. A bearing element is installed between the shell and the carrier and several hydraulic pressure generating devices are mounted between the carrier and the bearing element to urge the latter against the internal surface of the shell. The pressure generating devices are spaced apart from each other, as considered in the circumferential direction of the shell, and the cylinder chamber of each such device can receive pressurized hydraulic fluid at a different pressure. The axis of a main pressure generating device is normally located in the common plane of the axes of the shell and of the complementary roll. The other device or devices are installed at the one and/or the other side of such plane and can be operated to counteract forces acting substantially tangentially of the shell. The carrier and the bearing element have cooperating spherical, flat and/or cylindrical guide faces which enable the bearing element to pivot about an axis that is parallel to the axis of the shell.

Abstract: The present invention specifies a method for the verification of authenticity in a data carrier (1) by measuring permeability to an electromagnetic radiation in at least one region of the data carrier (1). Permeability is scanned over a regional area of the data carrier by means of a radiation detector (7) first in a calibration operation, in which the radiation intensity is adjusted, then in a reading operation at another position of the data carrier. The output signal of the detector (7) is coded and co-inscribed as additional information in a store of the data carrier with the information data during the initial inscribing of these data. In the reading and authenticity check scanning operation this information is compared with a corresponding additional information stored during the original data inscription.
