Filed: 2002-12-09
Granted: 2010-10-19
Abstract: Apparatus for drying a gas comprises an elongate housing having an inlet port and an outlet port for the gas. The housing comprises at least two axially separable parts which can be separated to allow access to the interior of the housing. A cartridge contains an adsorbent material through which gas can flow axially from an inlet end which is in fluid communication with the inlet port to the housing towards an outlet end which is in fluid communication with the outlet port from the housing. The cartridge has a plurality of flexible vanes at the inlet end which, when the cartridge is located within the housing, are twisted so that gas flowing over the vanes has a circumferential flow imparted to it around the axis of the cartridge.

Abstract: A method of hard-facing a steel casting is described in which a hard-facing, which comprises a weld alloy matrix and a hard particulate substance, is attached to the casting by welding. In some embodiments the matrix can be of a similar composition to the casting, and in other embodiments the hard particulates can be rounded and/or substantially spherical, or of a substantially even size. A method is also described for hardening and tempering a steel casting after attaching the hard-facing to the casting by welding. After hard-facing the casting is hardened and tempered by heat treatment. In one embodiment the hard-faced casting is heat treated by heating to a temperature in excess of the austenitising temperature of the steel and then cooled by quenching in an aqueous solution, followed by tempering. In one embodiment the steel casting is tempered at a temperature in the range about 550~C to about 700~C prior to hard-facing the casting.

Granted: 2011-08-09
Abstract: The present invention relates to a method and a system for creating three-dimensional models of objects from sets of arbitrary three-dimensional entities obtained from target surfaces. It also provides an efficient method for individually refining the alignment of curves to improve the accuracy of the surface model with a linear complexity with respect to the number of curves. The principle behind the invention is that a set of three-dimensional entities, at their approximate positions, creates a field from which the surface can be extracted. The field is constructed in a manner such that the three-dimensional entities are attracted toward the extracted surface. This attraction is used to accurately register each three-dimensional entity with respect to extracted surface. Through iterations, both the field and the entity positions are refined.

Abstract: Disclosed are nutritional compositions and methods of using the compositions for treating or preventing osteoporosis. The compositions comprise (A) those dried fruit solids that inherently comprise flavonoids, hydroxycinnamic acids, and a fiber component of which at least about 20% by weight is soluble fiber, and (B) a soluble, indigestible oligosaccharide in addition to any soluble fiber inherently in the dried fruit solids. The dried fruit solids may also be characterized as those selected from dried plum, dried grape, dried date, or dried fig. The combination of dried fruit solids (e.g., dried plum solids) and soluble indigestible oligosaccharides (e.g., fructooligosaccharides) have been found to be surprisingly more effective in affecting bone mineral density than either component when used alone, thus allowing for reduced concentrations of such ingredients in a nutritional product form such as a beverage or solid nutritional bar.
