  • Patent number: 4223090
    Abstract: A method of determining triglycerides in biological fluids according to an enzymatic reaction. In the reaction, a biological fluid is added to an enzyme reagent comprising a lipase, glycerol dehydrogenase (GDH), pyridine nucleotide (PN), a buffer, a tetrazolium compound and diaphorase, whereby the triglycerides are enzymatically hydrolyzed, and the resulting glycerol is oxidized to form a reduced pyridine nucleotide (PN) which reacts with said tetrazolium compound in the presence of the diaphorase to produce a colored formazan which is the reduced form of the tetrazolium, which color is measured at a wavelength ranging from about 475 to about 325 nm. The lipase is an enzyme obtained from Chromobacterium viscosum. In the enzyme reagent, there is from about 5.0 to about 15.0 I.U./ml of the glycerol dehydrogenase (GDH) present.

  • Patent number: 4194678
    Abstract: A shipping container formed by joining a base member having a floor, sides, and top with a reinforcing member having front and rear panels joined by a vertical support panel. These two members combine to form a crush resistant container. Preferably, there is a pocketed insert overlying the floor and held in position as an integral part of the container by sealing together the base and reinforcing members. The container is highly crush resistant and suitable for shipping bottles of liquid, such as those containing sterile intravenous solutions or other medical liquids.

  • Patent number: 4144969
    Abstract: A method is disclosed for beneficiating an apatitic phosphate ore containing an alkaline earth metal carbonate mineral impurity, which includes conditioning the phosphate ore in an aqueous conditioning slurry containing a cationic reagent at a concentration sufficient to reagentize the ore; and subjecting the reagentized ore to a froth flotation process wherein the apatite is recovered in the froth concentrate and the alkaline earth metal carbonate mineral impurity is rejected in the underflow tailing.
