Patent number: 9581582Abstract: In some variations, this disclosure provides a method of verifying the presence of an admixture in association with a solid base material, by combining the admixture with a stable inorganic tracer. A sample of the solid base material may be analyzed, using suitable analytical techniques, to detect the presence of the inorganic tracer in excess of any native inorganic tracer. When the inorganic tracer is positively detected, it is confirmed that the traceable admixture has been properly dosed within the base material. The inorganic tracer may comprise a rare earth metal, such as selenium, molybdenum, bismuth, and combinations, alloys, or oxides thereof, for example. The solid base material may be a cementitious material, in some embodiments. The traceable admixture may be a water-repellent admixture, in some embodiments.

Patent number: 7552623Abstract: A leak detection dye carrier is formed using a two-stage process (53). In a first stage, the dye carrier (52) is saturated with a mixture (54) of a dye powder and an evaporable solvent, such as alcohol. The solvent is permitted to evaporate leaving dispersed dye solids (56) on the dye carrier (52). In a second stage, the dye carrier (52) and dispersed dye solids (56) are immersed in a wet bath (58). The method may be a hybrid of dry and wet systems of placing dye onto a substrate carrier in which the wet bath is a mixture of a dye and a solvent, such as a system lubricant. Alternatively, the immersion of the dye carrier in the second stage may be limited in duration to prevent the dye solids in the first stage from being dissolved.Type: GrantFiled: May 5, 2004Date of Patent: June 30, 2009Assignee: Spectronics CorporationInventors: B.
