Abstract: A die assembly for a vacuum assisted die casting apparatus includes: a cover die half supporting a cover die, the cover die having a first chill vent surface; a moveable ejector die half supporting an ejector die, the ejector die half being configured to be moved along a first axis; and a moveable slide die supported by the ejector die. The slide die is configured to be moved along a second axis perpendicular to the first axis, the slide die having a second chill vent surface.

Abstract: A system for simulating in situ drilling and treatment conditions on a core sample from a subterranean formation. The system re-creates various subterranean loads and temperatures on a test sample representative of actual in situ conditions from the particular formation while a test structure within the system performs drilling activities on the core sample using drilling and treating under evaluation for use in the particular subterranean formation. Thus, the impact on selected drilling and treating fluids can be evaluated as well as the impact those fluids had on a sample from the subterranean formation under in situ conditions.

Abstract: A bag retention system and field configurable waste and recycling receptacle and receptacle systems that employ same. The bag retention system includes a peripheral side wall element having an upper portion defining an opening for receiving at least one bag, the peripheral side wall element having a bag opening and support member (e.g. an outwardly extending flange) about which an upper portion of a bag can be wrapped, and a tensioning element located below the flange and coupled to and extending outwardly from the side wall element, the tensioning element having means for releasably securing excess material from an upper portion of a bag, whereby a bag can be inserted in the opening with an upper portion thereof folded over and tightened around flange by pulling the upper portion of the bag taut around the flange and releasably securing the excess material to the tensioning element.

Abstract: The present invention provides an apparatus, method and computer program for processing documents using color marking. The apparatus includes a color scanner, a memory and a processor. The color scanner creates an image of each document. The memory stores one or more document processing instructions associated with the presence or absence of one or more color swatches within the image. The processor is coupled to the color scanner and the memory. In addition, the processor controls the color scanner, determining whether one or more color swatches are present or absent in the image and executing the document processing instructions associated with the presence or absence of the one or more color swatches.
