Abstract: An improved vertical shaft impactor rock crusher is provided. The improvement comprises an anvil having a front impact surface, a planar rear surface and a side surface extending between the front and rear surfaces. A shaft extends from the rear surface and can have a polygonal shaped cam lobe at the end of the shaft. When seated in the slot of a hanger bracket, the cam lobe keeps the anvil secured to the bracket while a side of the cam lobe rests on a seating block attached to the bracket to hold the anvil in an indexed position. When the impact surface becomes worn from use in the rock crusher, the anvil can be rotated within the bracket so that the cam lobe rests on an adjacent side thereby presenting an unworn surface to fracture feed rock in the rock crusher.

Abstract: The present application relates to an intraluminal thin film medical device (100) particularly well suited for occlusion of an aneurysm, vessel side branch or dissection of a body lumen or duct, such as an artery or vein. The medical device has a thin film tube (101) capable of being longitudinally stretched by the application of mechanical energy to achieve a smaller circumferential profile, and self-expand to the pre-stretched length and diameter upon release of the mechanical energy. To assist the thin film during expansion a plurality of slots (102) are incised in the tube wall. The slots open and assist the thin film tube to longitudinally stretch, and substantially close when the thin film tube self-expands to the pre-stretched length and diameter.

Abstract: According to a list of values distributed in a plurality of modules, it is possible to create a list in which the values are arranged in the ascending order without overlap. An information processing system includes a plurality of PMM which are connected by data transmission paths. Memory of the PMM has a list of values arranged in the ascending or descending order without overlap.  According to the order decided for each of the PMM and the list of values received from another PMM, a PMM judges whether it is a representative module representing at least one memory module holding the contained value for the values stored in the list (LOCAL LIST) of the values held by the PMM itself.  If the PMM is the representative module (RV-0 to RV-7), it stores information indicating that it is the representative module while correlating it with the stored value.

Inventor: MITCHELL KATHERINE P
IPC: C08K3/00
Filed: 2006-03-20
Abstract: A series of resins were synthesized using a range of bio-based materials to control the molecular architecture, and therefore the properties, of the inventive resins. The utility of these resins was demonstrated in the formulation of powder coatings, such as .beta.-hydroxy amide crosslinked and hybrid types. Generally, the bio-based resins flowed out on heating faster than conventional petrochemically-based resins, allowing the use of lower temperatures in the curing oven than is typically possible and a more active catalyst system, especially in the carboxylic acid-epoxy crosslinked hybrid coatings formulations.

Abstract: A mixed potential NOx sensor apparatus for measuring the total NOx concentration in a gas stream is disclosed. The NOx sensing apparatus (10) comprises a multilayer ceramic structure (30, 40, 50, 60, 70), and (80), with electrodes (34) and (84) for sensing both oxygen and NOx gas concentrations and includes screen-printed metallized patterns that function to heat the ceramic sensing element (32) and (82) to the proper temperature for optimum performance. This design may provide advantages over the existing technology by miniaturizing the sensing element to provide potentially faster sensor light off times and thereby reduce undesired exhaust gas emissions. By incorporating the heating source (52) and (54) within the ceramic sensing structure, the time to reach the temperature of operation is shortened, and thermal gradients and stresses are minimized. These improvements may provide increased sensor performance, reliability, and lifetime.
