Title: Magnetic flowmeter with pulsating field - has increased scan frequency and voltage controlled resistor suppressing unwanted oscillations
Inventor: HETTICH HEINZ
IPC: G01F1/58
Filed: 1979-08-30
Abstract: A magnetic flowmeter with a pulsating magnetic field has a field coil arrangement producing a magnetic field in the measurement tube carrying the fluid. It achieves accurate measurements whilst enabling a higher scanning frequency to be used. A voltage controlled resistor (3) and a capacitor (2) connected in series form a circuit connected in parallel with the field coil (2). The voltage controlled resistor presents a high impedance path for applied voltages below a threshold level and a low impedance for higher voltages. The transition voltage is greater than the voltage amplitude of the damped oscillation of the oscillator formed by the field coil and capacitor. Unwanted oscillations are thus suppressed whilst the scanning frequency can be raised.

Patent DE-3039483-A1 (DE)
Inventor: REICHL ALFRED
IPC: G01B7/30
Filed: 1980-10-18
Abstract: A position measuring instrument of the type having a scale and a scanning unit is provided with a plurality of reference marks on the scale. An identification mark is associated with each reference mark, and each identification mark is uniquely coded. The scanning unit operates to read the identification marks and to generate identification signals which are applied to a comparator or to a computer. The comparator or computer compares the identification signal corresponding to each reference mark with a set of designation signals. Only if a correspondence is found between the identification signal and one of the designation signals is the reference mark allowed to go into operation. Thus, by merely changing the designation signals electronically, any desired subset of a total number of reference marks can be enabled. The selected reference marks can readily be changed electronically without physical manipulation of the measuring instrument.

Title: Play device
IPC: A63F9/08
Filed: 1981-02-05
Abstract: The play device is a puzzle toy with balls, which is intended to develop logical thinking and combination skill. The playing surface of the play device is formed by the circumferential walls of a plurality of discs (10, 20, 40) which are rotatable relative to one another and in the outer walls of which are provided hollowed-out grooves (12, 22, 42) offset relative to one another. In specific rotary positions of the discs (10, 20, 40), the grooves (12, 22, 42) in the individual discs are aligned with one another. A ball (30) is located in each groove of each disc. In the lowest disc (10), a ball space can be freed by pressing a ball into the interior of the disc (10). As a result of the rotation of the discs (10, 20, 40) and as a result of the movement of the balls (30) along the grooves aligned with one another, free ball space can be brought into any position. Accordingly, the individual balls on the playing surface can also be rotated and displaced into any position. When the free ball space arrives again at the location of the pressed-in ball, this ball takes up its original place in the playing surface again under the effect of a compression spring. The object of the game is, for example, to arrange balls of the same colour next to one another in the respectively mutually aligned grooves (12, 22, 42) of the discs (10, 20, 40). <IMAGE>
