Portable hood

A polyol ester or poly-alkylene glycol lubricant is tagged by adding to the lubricant a chemical marker which is stable over the temperature cycling range of a refrigerant. In testing for the presence of the marker, a sample of a lubricant is obtained, and the sample is diluted in a sufficient volume of an organic solvent such that subsequent admixture with an aqueous solution will not result in emulsification. The diluted sample is extracted with an aqueous solution appropriate for the marker. Simultaneous with or subsequent to extraction, a chromophoric reaction of the marker is induced, whereby a readily identifiable color is observable.

Method of tagging and subsequently indentifying refrigerant lubricants

A dye which is either 2-naphthalenol (phenylazo) phenyl azo alkyl derivatives and 1,4-dialkylamino anthraquinone is added to sufficient non-ionic surfactant to compatibilize it with ethanol and an solvent to produce a homogeneous solution. The homogeneous solution is added to ethanol in an amount to provide a desired amount of coloration to the ethanol.

Method of introducing dyes to ethanol

Petroleum fuels are tagged with markers having the formula: ##STR1## where R.sup.1 and R.sup.2 are selected from H, methyl, ethyl, methoxy, halogen, cyano and nitro and R.sup.3 is selected from methyl, methoxy methoxyethoxy and morpholino.

Acid extractable petroleum fuel markers

A tag is added to an asphalt additive, typically an anti-stripping agent. The additive dye is mixed with other components of an asphalt composition and melt processed at 300.degree. F. (149.degree. C.) or above to produce an asphalt composition. Presence of the tag to identify presence of the additive is performed by dissolving the asphalt portion of the composition in a water-immiscible solvent and then extracting the tag in an acidic aqueous solution and developing a color with a diazo compound.

Tagging and identifying asphalt additives

Liquid petroleum products are tagged with a marker which is a compound or mixture of compounds having the formula: ##STR1## wherein R.sup.1 is C.sub.1 -C.sub.6 alkyl, and R.sup.2 and R.sup.3 are nothing or --O--(C.sub.1 -C.sub.3 alkyl).

Markers for petroleum, method of tagging, and method of detection

A liquid dyestuff, useful as a major component of a ballpoint ink is prepared. A dye base, having both a sulfonic acid group and an azo group bonded to the same aromatic ring system, is provided in the aqueous phase of a two-phase system in which the organic phase is about 30 percent or more benzyl alcohol. In this two-phase system, the dye base is complexed with a diaryl quanidine, and the resulting dye concentrates in the organic solvent phase.

Method of preparing a solution of sulfonated aryl azo/diaryl

A durable, lightweight, non-metallic replacement rack, or tray assemblage, which is uniquely designed to be readily interchangeable with the metal racks normally provided by the leading manufacturers of refrigerated cases adapted for use in displaying produce, meats, deli items and the like. The novel tray assemblage of the invention is constructed of lightweight, high density, injection molded polyethylene (structural foam). The unique assemblage embodies several interlocking, interchangeable parts such as partitions, elevated trays and data display standards, which can be interconnected so as to substantially increase the versatility of the assemblage over the metal racks of the type generally furnished by the display case manufacturers.
