  • Patent number: 5940177
    Abstract: A method and apparatus for determining the size distribution of at least two different types of fluorescent or fluorescently stained particles in a sample by radiating light into a stream of singled particles and recording and analyzing both the scattered light and the fluorescent light. A relative particle size distribution for each individual particle type (T.sub.k) is calculated and then the relative particle size distribution for the individual particle types is normalized forming a joint relative particle size distribution of the at least two particle types with respect to one another.

  • Patent number: 5081939
    Abstract: A bar for a rotary grate is of T-section and has an enlarged head and a fin projecting inwardly therefrom. The head is formed with an end face directed outward from the fin and a pair of substantially parallel side faces extending inward obliquely from the end face. The side faces extend at an angle of between 40.degree. and 75.degree., preferably about 60.degree., to the end face. Thus air exiting from inside the roller-grate drum flows obliquely to a radius from the drum-rotation axis. This ensures that even if the material being burned does not form a continuous layer on the surface of the roller, the air will be likely to impinge this material. The fin extends generally centrally from the head and has a centerline that generally bisects the head. The bar has ends formed with blocks projecting to opposite sides of the bar so that blocks of adjacent bars can interfit.

  • Patent number: 4537139
    Abstract: A drum-shaped grate of an incinerator includes a plurality of cylindrical drums, the grate covering of which is formed of a plurality of suspended middle grate bars which are combined in segments and arrested by fixed grate bars. The adjacent grate bars in the circular direction are suspended on bar carriers and the lateral faces of each two adjacent grate bars are spaced from each other by spacers. The surfaces of the spacers positioned between each two adjacent grate bars and abutting against each other are flat and smooth. Due to a possible relative displacement of the middle grate bars in their longitudinal direction owing to the placing of the spacers between the adjacent bars a clogging of the air slots formed between the grate bars would be prevented.
