Abstract: Disclosed herein is a system for treating a magnesium or a magnesium alloy substrate comprising: a first pretreatment composition comprising a fluorometallic acid and free fluoride in an amount of 10 ppm to 500 ppm based on total weight of the first pretreatment composition and having a pH of 1.0 to 4.0; and a second pretreatment composition comprising a lanthanide series metal, the second pretreatment composition being substantially free of peroxide. Also disclosed are methods of treating a magnesium or magnesium alloy substrate. Treated magnesium and magnesium alloy substrates also are disclosed.

Abstract: Disclosed is a sealing composition for treating a metal substrate comprising: a polyolefin component; and a colloidal layered silicate. Also disclosed is a system for treating a metal substrate comprising: a cleaner composition; and/or a pretreatment composition for treating at least a portion of the substrate, the pretreatment composition comprising a Group IVB metal; and a sealing composition for treating at least a portion of the substrate treated with the cleaner composition and/or the pretreated composition, the sealing composition comprising a polyolefin component. Also disclosed is a method of treating a substrate comprising contacting at least a portion of a surface of the substrate with any of the compositions disclosed herein or any of the systems disclosed herein.

Abstract: The present invention relates to a new family of structurally and functionally related nucleic acids and proteins, designed the CATERPILLER family, which is characterized by landmark structural motifs including a nucleotide binding domain and leucine-rich repeat domains.

Abstract: A case for packaging and storing a magnetic disk cartridge is disclosed. The case includes a tray that slides into a housing, and a seal between the tray and the housing. The seal protects the cartridge from dust and contaminant infiltration and from physical damage. The tray forms a receptacle for receiving and holding the cartridge and includes a hinge for enabling a front portion of the tray to pivot downward to provide clearance to insert and remove the cartridge by sliding therein. The case includes a latching means for latching the tray and housing together, a transparent panel for viewing the cartridge while it is inside of the case, a clasp that prevents the tray from being fully removed from the housing, and unique key members that mate to corresponding key grooves in a JAZ cartridge.
