Title: Headlight aiming apparatus and display
Inventor: HOPKINS EVAL L
IPC: G01M11/06
Filed: 1992-01-29
Abstract: An apparatus and method for aiming vehicle headlights   and   for   visually   displaying   the illumination  patterns  of  the  headlights.   The apparatus focuses the light beam on a screen and senses the intensity of the light in each cell of a matrix of cells overlying the reflected light beam with an image sensor.   The apparatus generates an electrical signal for each cell indicative of the intensity  of  the  light beam  in each cell.   The apparatus includes a computer for comparing at least some of the electrical signals to each other and with established  criteria  to  determine  whether  the headlight is aimed within a prescribed degree of accuracy.   The apparatus describes the illumination pattern of a headlight by visually displaying at least some  of  the  electrical  signals  i.e.  the  light intensities and their locations, on a display.  The illumination pattern can be displayed as a series of isocandela lines, or can be displayed as a simulated headlight  illumination pattern on a road surface. Exemplary objects can be included on the road surface at selected intervals to indicate relative distances. The headlight illumination pattern can be compared to a properly aimed,  simulated headlight illumination pattern to indicate the necessary aiming correction. The apparatus further includes digital and graphic indications of the relative deviations between the headlight illumination pattern and a properly aimed headlight  illumination  pattern.     The  apparatus preferably includes an aiming probe for centering the headlight relative to the lens.

Title: Process for regenerating spent bleaching earth
Inventor: MAES PIETER J A
IPC: C11B13/04
Filed: 1992-08-27
Abstract: The present invention relates to a process for the regeneration of spent bleaching earth, comprising an oxidative heat treatment in which the amount of oxygen supplied exceeds the stoichiometrical requirement of complete oxidation of all organics present in the spent bleaching earth, wherein the spent bleaching earth and the oxygen are blown through a stationary fluidized bed of inert granulate material. The stationary fluidized should be as high as to limit the temperature in the freeboard to less than 1000 DEG C. As a matter of fact, it has been found that, if the fluidized bed is not high enough, the oxygen required to burn off the organics content of the spent bleaching earth would blow out the powdered bleaching earth from the bed at the stage of incomplete oxidation of the organics present on the earth, resulting in an uncontrolled temperature rise in the freeboard and local overheating of the bleaching earth.

Inventor: STILKERIEG BERTHOLD
IPC: C21C5/46
Filed: 1992-11-13
Abstract: This invention concerns a process for the reliable avoidance of slag contamination of the converter tapping steel by flush slag. In accordance with the invention a plastic, workable stopper made of fire-proof material containing silicic and oxidic components as well as suitable binding agents is used for this purpose. The stopper is introduced so far into the tapping channel with the help of a setting device that its front surface, terminated with a funnel-shaped compression plate, almost aligns flushly with the interior side of the converter, and it fills in the diameter of the tapping channel as a result of being compressed, creating such a plane treat the flush slag occurring during tipping of the converter is reliably directed past the tapping channel. Stopper systems used up to now had the disadvantage that age-dependent enlargements of the tapping channel had a detrimental effect on the functioning of the stopper. The new plastic stopper adapts to a large range of tapping channel diameters in accordance with the process used.
