Title: Measuring device for measuring a path error in the pouring region of a continuous casting plant
Inventor: WIEGARD GUSTAV ADOLF
IPC: B22D11/20
Filed: 1987-08-08
Abstract: The invention relates to a measuring device for determining the wear on open-ended moulds for continuous casting plants and for measuring the path error of the foot rollers or strand rollers adjoining the mould. A template-like basic element is positioned in the mould, an unworn reference surface of the mould serving as a bearing surface and hence as a basis for the alignment of the measuring device. A reference surface corresponding to the desired contour of the casting path serves as a basis for a measuring element, displaceable thereon, which, by longitudinal displacement, permits sensing and thus measurement of the mould and of the adjoining rollers.

Title: Measurement converter for distance and/or angle measurements on rotating parts in accordance with the carrier-frequency principle
Inventor: UTZ WOLFGANG
IPC: G01P3/481
Filed: 1988-02-15
Abstract: In this converter, an amplitude change of the carrier frequency signal dependent on the magnitude to be measured is produced. To obtain good measurement results even with a non-constant speed, the measurement converter is developed in such a manner that a phase-locked loop is provided which controls the frequency of the oscillator to a defined multiple of the frequency of rotation of the rotating part. The invention can be applied in the monitoring of rotating parts on machines. <IMAGE>

Title: Equipment for the detection of faults in a controller
Inventor: SEKIGUCHI AKIRA
IPC: G05B23/02
Filed: 1988-06-16
Abstract: The invention relates to equipment for the detection of a fault in a controller 10, which has a microcomputer 12 which is connected between an input terminal 20 and an output terminal 30 of the controller 10. The microcomputer 12 is programmed to carry out a normal control operation and a self-test operation and to determine whether the conditions for entry into the self-test operation are fulfilled, in order to select one of the two types of operation. An external circuit is connected between the input terminal 20 and the output terminal 30 of the controller 10, in order to produce a predetermined relationship between the voltage levels of the input terminal and the output terminal. In the self-test operation, the microcomputer gives out a control signal to set the output terminal 30 either to a high or to a low logical voltage level. The microcomputer 12 establishes whether an input signal, which is fed to the microcomputer 12 via the input terminal and has the predetermined voltage relationship to the output terminal 30, has a voltage level which corresponds to the voltage level of the output terminal 30, and establishes that a fault exists when the input signal is not at the corresponding level. The microcomputer 12 causes the fault to be indicated in an external indicator device when the microcomputer detects the error. <IMAGE>
