Abstract: A composition for use in treating skin disorders and especially acne without the side effects of steroids, antibiotics, anti-fungal, and other treatments (e.g. UV radiation, light therapy, etc.). The orally-administered composition is a compound of sphingolipid and an ingestible sulfur (including any sulfur compound, sulfur-containing moiety, or sulfur salt). In a preferred embodiment the present composition also includes an adjuvant, preferably zinc and/or a proanthocyanidin, preferably from grape seed extract, and other excipients for taste, consistency and/or coloring. The above-described composition is orally administered in tablet form pursuant to a prescribed protocol of therapeutic doses to a subject.

Abstract: This is an apparatus and associated method for rolling large pieces of a flexible media such as completed plots produced by a plotting pen plotter. The rolling mechanism is placed adjacent an exit of the pen plotter to received ejected media pieces therein. Upon detecting the leading edge of a media piece while in an open position, the mechanism closes to form a guide slot to a cylindrical rolling chamber. The media piece is then urged along the guide slot and into the rolling chamber where it is rolled by a drive roller. Upon detecting the trailing edge of the media piece, the mechanism opens allowing the rolled media piece to fall into a receiving bin. The stationary portion and the rotating portion are formed of a plurality of slats having low contact area edges disposed for media pieces to move along whereby the media pieces move along a low friction path.

Abstract: Process and facility for upgrading heavy hydrocarbonaceous materials for making coke suitable for metallurgical purposes comprises mixing the heavy hydrocarbonaceous materials with a diluent having a closely controlled boiling range and subjecting the oil diluent mixture to distillation and careful fractionation so as to maximize liquid yields in the coking step.

Abstract: Apparatus for upgrading heavy hydrocarbonaceous materials for making coke suitable for metallurgical purposes comprises mixing the heavy hydrocarbonaceous materials with a diluent having a closely controlled boiling range so as to facilitate transport, dehydration and desalting of the crude oil. In addition, the diluent aids in controlling temperature and residence time of the crude thereby avoiding premature decomposition.
