  • Patent number: 11661258
    Abstract: A packaging system that maintains the free flowing characteristic of solid materials contained therein. The packaging system includes a container, a cover, a vapor permeable bag, a vapor impermeable liner and at least two desiccant snakes. The vapor permeable bag has an opening for receiving solid materials and is formed from cloth or continuous fibers of high-density polyethylene that are randomly distributed and non-directional. The vapor impermeable liner surrounds the vapor permeable bag and provides a moisture barrier. The desiccant snakes are disposed between the vapor permeable bag and the liner. Each snake includes two or more desiccant packages formed from a vapor permeable material through which moisture can freely pass. The desiccant packages contain clay, silica, or molecular sieves.

  • Publication number: 20170282350
    Abstract: A protective guard for a circular blade having a plurality of projecting edges along the circumference is provided. The protective guard includes an anchor link with a first member, a latching link detachably connectable to the anchor link, and a plurality of connected pivoted links extending between and connected to the anchor link and the latching link. The first member is adapted to engage one of the plurality of projecting edges of the circular blade, the plurality of connected pivoted links are adapted to cover the plurality of projecting edges along the circumference of the circular blade and the latching link is connected to the anchor link to secure the protective guard to the circular blade.

  • Publication number: 20170112768
    Abstract: An improved excipient comprising substantially homogeneous particles of a compressible, high functionality granular microcrystalline cellulose based excipient is provided. The improved excipient comprises microcrystalline cellulose and a binder, and optionally a disintegrant, and is formed by spraying a homogeneous slurry of the components. The excipient provides enhanced flowability/good flow properties, excellent/high compactibility, and increased API loading and blendability as compared to the individual components, and as compared to conventional excipients formed from the same materials. The improved excipient has strong intraparticle bonding bridges between the components, resulting in a unique structural morphology including significant open structures or hollow pores. The presence of these pores provides a surface roughness that is the ideal environment for improved blending with an API.

  • Patent number: 9570343
    Abstract: The present invention is a new formulation and process for treating TiN semiconductor devices having a high aspect ratio structure formed thereon. The new composition is designed to be used in the chip making process between cleaning a wet etched memory device and its final rinse/drying process. It is intended to include the treatment in order to prevent collapse of the high aspect ratio TiN structure found on the semiconductor device.
