Abstract: A weather-based financial index is based at least in part on weather. The index may take into account any of a variety of weather factors, such as temperature, precipitation, humidity, number of sunny or overcast days in a period of time, number of freeze days in a period of time, etc. Weather factor value(s) are combined with one or more financial components to provide the weather-based financial index. The index may be traded on an exchange, such as the New York Mercantile Exchange (NYMEX). The value of the index may be calculated based on any period or on any geography (or combination of geographies). Historical values of the index or component(s) thereof may be used to predict future values of the index. Values of the index may provide insight into the direction of a component of the index, a market or industry corresponding to the component, or the index itself.

Abstract: Embodiments of an apparatus including a rolling contact bearing are disclosed.

Abstract: A pack of tissues includes multiple interfolded tissues arranged in a stack and an external envelope enclosing the stack. The external envelope includes a dispensing orifice and the tissues are folded so as to include a leading panel, an optional central panel, a trailing panel, a leading fold and an optional trailing fold, wherein the leading fold separates the leading panel from the central panel and the optional trailing fold separates the optional central panel from the trailing panel. The stack has a first tissue and an second tissue, the second tissue being positioned next to the first tissue in the stack and further away in the stack from said dispensing orifice. The tissues are interfolded so as to have an overlapping portion of the first tissue under a portion of the second tissue. The surface area of the overlapping portions is not constant throughout the stack; preferably it increases with the distance to the dispensing orifice.

Abstract: An apparatus, method and system are provided for a modular in-frame pumped refrigerant distribution system. Specifically, a micro-channel heat exchanger is positioned in an equipment cabinet close to equipment that generates heat. More specifically, the micro-channel heat exchanger may be positioned on a) a shelf above the equipment, b) the back side of the equipment, or c) a shelf below the equipment. The micro-channel heat exchanger is operable to receive a refrigerant supplied by an external heat exchanger along a primary flow path, transfer heat from air above and/or near the equipment to a coil of the micro-channel heat exchanger, circulate the refrigerant to extract the heat, and return the refrigerant with an extracted portion of generated heat to the external heat exchanger along a secondary flow path. The external heat exchanger may remove extracted heat from a building via a building chilled water system or an outdoor condenser unit.

Abstract: A propulsion or pumping device which includes two counter-rotating shafts (3, 4) each carrying at least one impeller (7, 8), wherein each impeller (7, 8) can deflect by a predetermined amount in directions substantially perpendicular t to the longitudinal axis of the shaft (3, 4) on which the impeller (7, 8) is mounted.

Abstract: In one embodiment a closure for a supply container includes: a spout affixed to the container; a plug configured to plug the spout in a partially inserted position from which the plug may be easily removed from the spout and to plug the spout in a fully inserted position from which the plug may not be easily removed from the spout; an opening in the plug through which material in the container may flow when the plug is inserted into the spout; and a breachable seal sealing the opening.
