441 results about "Working capacity" patented technology

“Work capacity refers to the general ability of the body as a machine to produce work of different intensity and duration using the appropriate energy systems of the body” (Siff, 2003). All athletes can benefit from improved work capacity. This is particularly true for combat athletes.

Method for reducing emissions from evaporative emissions control systems

Disclosed is a method for sharply reducing diurnal breathing loss emissions from automotive evaporative emissions control systems by providing multiple layers, or stages, of adsorbents. On the fuel source-side of an emissions control system canister, high working capacity carbons are preferred in a first canister (adsorb) region. In subsequent canister region(s) on the vent-side, the preferred adsorbent should exhibit a flat or flattened adsorption isotherm on a volumetric basis and relatively lower capacity for high concentration vapors as compared with the fuel source-side adsorbent. Multiple approaches are described for attaining the preferred properties for the vent-side canister region. One approach is to use a filler and/or voidages as a volumetric diluent for flattening an adsorption isotherm. Another approach is to employ an adsorbent with the desired adsorption isotherm properties and to process it into an appropriate shape or form without necessarily requiring any special provision for dilution. The improved combination of high working capacity carbons on the fuel source-side and preferred lower working capacity adsorbent on the vent-side provides substantially lower diurnal breathing emissions without a significant loss in working capacity or increase in flow restriction compared with known adsorbents used in canister configurations for automotive emissions control systems.

Instantaneous milling force modeling method in free curve shape part peripheral milling process

The invention discloses an instantaneous milling force modeling method in the free curve shape part peripheral milling process, used for solving the technical problem of big calculation working capacity of the traditional instantaneous milling force modeling method in the free curve shape part peripheral milling process. The invention has the technical scheme that the equivalent feed direction, the equivalent normal vector and the equivalent curvature which correspond to an equivalent tool position on a theoretical tool path replace the feed direction, the normal vector and the curvature which correspond to the tool position on the actual tool path so as to avoid the phenomenon of the forecasted milling force mutation caused by using a non-second order continuous actual tool path forecasted milling force; while the eccentricity is considered, an analytic model of instantaneous undeformed cutting thickness is deduced, and the instantaneous undeformed cutting thickness does not need to be worked out by using a numerical calculation method.
