Title: Circuit arrangement for generating noise-free switching pulses
Inventor: EIFFERT KARL LUDWIG DIPL ING
IPC: H02P6/00
Filed: 1983-05-30
Abstract: A circuit arrangement is proposed which filters out noise signals which influence, for example, the sensor signals of a direct-current motor. This is achieved by the fact that a monostable flip flop is set by the first rising edge of the sensor signal (E) and the monostable flip flop time is set in such a manner that it only returns to the rest position after the noise signals have decayed. The next falling edge of the sensor signal (E) causes a second monostable flip flop to be set, the on-time of which is also sufficiently great for the noise signals to have decayed. The monostable flip flops are followed by an AND gate and an OR gate in such a manner that the output signal (A) satisfies the following logic relation:  A = (Q2 . E) + Q, where Q1 is the output signal of the flip flop circuit (13) and Q2 is the inverted output signal of the flip flop circuit (15). <IMAGE>

Title: Power-fed subscriber terminal of a telecommunication system
Inventor: ZSCHAECK THOMAS DIPL ING
IPC: H04M19/08
Filed: 1983-08-30
Abstract: Power-fed subscriber terminals can be fed with the power of a d.c. loop current in a telecommunication system from a central facility via a telecommunication line. In the subscriber terminal there may be provided a shunt controller, which regulates the value of the operating voltage to a value predetermined by a reference voltage. In order to bridge interruptions in the d.c. loop current, a charging capacitor may be provided in the subscriber terminal. Dialling is performed in the subscriber terminal by means of a control device and a dialling device. In order to be able to cover the increased power consumption caused by the dialling device even over a lengthy period of time, the control device changes the value of the operating voltage when in the dialling state from the value when a connection has been established. An increase in the value of the operating voltage can be achieved in this case by switching a resistor between a connection terminal of the operating voltage and a pick-off of a voltage divider circuit in the shunt controller.
Patent DE-3335421-A1 (DE)
Inventor: MAGORI VALENTIN DIPL PHYS
IPC: G01S7/52
Filed: 1983-09-29
Abstract: A method for evaluating echo signals transmitted and received by an ultrasonic transducer in a sensor of a movable mechanical element, such as an arm of an industrial robot, has the steps of receiving and storing the arriving echo signals in chronological sequence in a memory, the chronological sequence of the signal being converted into a corresponding sequence of memory positions, with successive sequences of echo signals of successive transmit pulses being stored in the same sequences of the memory positions. Integration of the echo signals of the successive sequences stored in the memory positions are undertaken such that the local shift of the ultrasonic transducer disposed on the moveable element which occurs between respective transmit pulses is compensated relative to chronologically adjacent pulses and the pulses reflected from a target are more easily identified.

Title: Method for determining particle size in a polycrystalline material
Inventor: ARNOLD WALTER K DR RER NAT
IPC: G01N29/11
Filed: 1984-04-04
Abstract: In a method for determining particle size in a thin sheet of a polycrystalline material, the frequency-dependent attenuation of the frequency components of an ultrasonic pulse insonifying the material is evaluated, the ultrasonic pulse having been generated with the aid of laser excitation. The width of the exciting laser pulse in this method is set in such a way that the wavelength assigned to the maximum of the frequency spectrum of the ultrasonic pulse in the material is about three times to thirty times the expected particle size. In order to determine the attenuation, the frequency spectrum of the ultrasonic pulse of the first and second rear wall echo is measured. Based on the frequency-dependent function of the attenuation, the particle size of the polycrystalline material is finally calculated.

Title: Method for testing coins for their weight, for limiting the maximum filling quantity of the coins inserted in the coin-guide channel and for testing and sorting out coins knurled in the edge region in self-service machines
Inventor: LUDWIG MAX
IPC: G07D5/04
Filed: 1984-06-25
Abstract: Method for testing coins for their weight, for limiting the maximum filling quantity of the coins inserted in the coin-guide channel and for testing and sorting out coins knurled in the edge region in self-service machines. The object of the present invention is to provide a method and a device for carrying out the method, in which too light coins (5, 6) are separated reliably, the particular coin inserted when the maximum filling quantity in the coin-guide channel (2) is reached is ejected, and knurled coins are not fed to the collecting device. This object is achieved by means of a rocker (9) projecting into the coin-guide channel (2) and having two extensions (12, 13) possessing run-on slopes, the extension (12) located first in the direction of insertion being pressed constantly into the same position by a spring (11). Too light coins, when they meet the slope (12), are deflected and are fed to the rejection channel. Whilst normal coins (5, 6) pass the said extension (12), at a specific filling quantity the second extension (13) of the rocker (9) is blocked by the coin last inserted. A subsequent coin is deflected via the extension (12), which no longer springs out, and is likewise fed to the rejection channel. Furthermore, a catch lever (20) projects into the coin-guide channel (3) in the region of the rocker and stops coins of identical diameter which are knurled in the edge region. <IMAGE>
