Abstract: A media disc storage device according to the present invention includes a first and second vertical wall with a shelf attached to the first and second vertical walls and extending therebetween in a generally horizontal configuration. The shelf defines a plurality of slots each capable of receiving a media disc therein.

Abstract: A pipeline pig suitable for use in cleaning deposits and buildup from an interior surface in a pipeline is also particularly suited for applications wherein the pipeline has a series of bends, right angles or even plug headers. The pig is suitable for bidirectional travel, having front and rear hemispherical noses. The pig is constructed in a manner that facilitates a greater degree of elongation and deformation than is possible with known pipeline pigs, while still providing the radially outward bias that is required to effectively scrape the sidewalls of the pipeline. A cover carries a plurality of metal studs arrayed about the cylindrical middle portion, and encloses an internal core. The core is formed in a mold from a mixture of resin and ISO, resulting in a pig having superior ability to elongate and deform, if needed, while still effectively scraping the sidewalls of the pipeline.

Abstract: A fluid-flow restricting apparatus for mixing fluids employs a body member housing elongate flow restrictors (typically capillary tubes) which restrict the flow of the fluid therethrough. Demountable fluid-tight seals are provided between the capillary tubes and passages in the body in which the tubes are housed. An inlet header is demountably attached to the body so as to distribute fluid to the capillary tubes. There is a common outlet passage communicating with the outlet ends of the capillary tubes. The inlet header may be fed with the fluids to be mixed from a pressure regulation system and has several inlets. Valves are operable to select which header inlets are placed in communication with the respective fluids to be mixed.
