Patent DE-4121318-A1 (DE)
Title: Determn. of position of phase boundary of material in metallurgical containers - using electromagnetic sensors in container wall provided with outlet opening
Inventor: JULIUS EDMUND DR ING
IPC: B22D37/00
Filed: 1991-06-27
Abstract: Determining the phase position of the contents in a metallurgical container involves use of electromagnetic sensors in the container wall provided with an outlet opening. Within the distance between the sensors, the horizonta section of the container bottom is reduced at least once towards the outlet opening. There are at least two sensors (8,9) in the funnel shaped or stepped bottom of the container (1). The rate of fall of the phase boundary is determined as a function of the distance between successive sensors, the variation of the horizontal bottom section and the time between the sensor reactions. The variation of the horizontal bottom section can be continuous or discontinuous. The electromechanical sensors are connected in series so that the signals from them are cancelled out, when the entire container bottom is covered by the melt. USE/ADVANTAGE - Used e.g. with casting ladles to determine an impending entry of slag into the outlet stream. In contrast to prior art it does not require the presence of slag in the outlet stream, and can be used with containers provided with a plug type closing device. It is insensitive to container lining wear and is suitable for accurate determn. of the level of the melt surface.

Filed: 1992-02-14
Abstract: The invention relates to a process for determining the quality of a single superconducting film formed on a substrate with the aid of a resonant cavity and a device for implementing such a process. The object of the invention is to provide a process facilitating the quality control of individual thin films. In the process of the invention, the superconducting film is bonded to the wall of a resonant cavity as at least a part thereof. In addition, a dielectric is secured to the surface of the superconducting film.

Title: Detecting moisture on road surface from vehicle - detecting water spray noise or wheel rolling noise, bandpass filtering, forming effective value, low-pass filtering, compensating for other parameters e.g. speed or tyre pressure and relating to wetness.
Inventor: GOERICH HANS-JUERGEN DIPL ING
IPC: G01H1/00
Filed: 1992-04-22
Abstract: The method involves detecting the noise of water spray or the rolling noise of at least one wheel of a vehicle as it is driven over the surface. The noise sensor's output signal is band-pass filtered to isolate a frequency range characteristic of moisture on the road. The effective value of the filtered signal is formed and passed through a low-pass filter. The effective value is associated with a value for the moisture on the road whilst compensating for the influence of parameters other than moisture on the effective value. The moisture value is output. USE/ADVANTAGE - Enables continuous measurement of moisture on road surface for use in vehicle, e.g. by anti-lock braking system.
