Patent CA-2070146-C (CA)
Inventor: NYMAN BROR G
IPC: B03D1/22
Filed: 1992-06-01
Granted: 1998-07-21
Abstract: The present invention relates to a method for concentrating a certain mineral fraction attached to air bubbles from a slurry to the foam layer accumulated on the surface, so that the concentration takes place in three different mixing zones.  The apparatus of the invention is formed of a colon-like flotation arrangement and of flow guides, a flow attenuator and an agitator belonging thereto.  The flotation reactions are created in the bottom zone, wherefrom air bubbles and mineral particles carried by them are directed in a controlled fashion onto the surface of the apparatus. The flotation apparatus is so designed, that a strong agitation in the bottom zone can be used without causing harmful separation of the foam in the bottom part of the apparatus.

Granted: 1996-06-18
Abstract: The present invention provides an improved method for staining slides using immunochemical reagents.  The method com-prises the following steps.  The assay region of a slide (the region containing the tissue section) is washed with an improved rin-sing solution comprising water and a detergent.  An evaporation inhibitor liquid is applied to the slide to cover the assay region. For antigens requiring unmasking the tissue section is combined with an improved, stabilized proteolytic enzyme solution.  The slide is rinsed, and the evaporation inhibitor liquid is reapplied to the slide.  A primary antibody in an improved diluent contain-ing globulins from the same species as a second antibody is combined with the tissue section for a time sufficient for substantially complete antibody binding. The slide is rinsed, and the evaporation inhibitor liquid is reapplied. A labeled second antibody in the improved diluent is combined with the tissue section for a time sufficient for substantially complete antibody binding. The slide is rinsed, and the evaporation inhibitor liquid is reapplied to the slide.  Color development reagents, including, in a preferred em-bodiment, a stabilized diaminobenzidine (DAB) solution, are combined with the tissue section for a time sufficient for color de-velopment. Following rinsing, the tissue section is ready for analysis.

Abstract: Reinforced concrete members consisting of a high-strength concrete are subject to explosive spalling. Such spalling can be prevented by the introduction of a capillary system into the concrete of such members, containing substantially linear capillaries having a diameter of at least 3 mm and a length of at least 5 mm.            This capillary system can be built during or after the hardening of the concrete without impairing the other desired properties of the concrete or mortar, or it can first be produced under the fire attack. This can be effected with fibers which form the capillaries by dissolution, softening, decomposition, shrinkage or melting and which, due to their shape, i.e. diameter and length, and the incorporated amount, correspond t< the desired capillaries.            As to the columns made of fiber concrete, if desired with addition of the finely-dispersed silicic acid, a classification under fire-resistant class F 180-A is possible.
