Patent CA-2264144-C (CA)
Inventor: STORMO KEITH E
IPC: B01F7/00
Filed: 1997-09-03
Granted: 2008-06-03
Abstract: Embodiments of a remediation reactor and mixer/contactor blade for the reactor are shown and described, the reactor (11) being for containing a liquid slurry, suspension or settled bed of solid particles containing mi-croorganisms. Inside the vessel is a supply conduit and at least one generally horizon-tal stirrer blade (27) in fluid connection with the supply conduit. The stirrer blade is a mixer/contactor which has a leading side hav-ing openings through which fluid may pass.  The stirrer blade rotates in the vessel, and this rotation is made easier by the hydraulic forces of fluid flowing out from the stirrer blade. The flowing fluid creates a fluidization zone in the slurry, suspension or settled bed at or near the leading edge of the stirrer blade.  The fluidization zone is less dense than the rest of the sediment bed, and the stirrer blade tends to rotate into the fluidization zone. This way, controlled rotation of the stirrer blade may be created near the bottom of the vessel, enhancing mixing of the microorganisms with the slurry, suspension or settled bed in the vessel, without unnecessarily damaging the microorganisms, especially when the flowing fluid contains contaminants which are nutrients for the microorganisms. Also, shown and described is a vessel which incorporates a mixing blade through which a gas and/or a liquid is recirculated. The mixing blade is rotated through a sand layer or other settled bed of solid particles, which acts as a medium supporting microbial growth and/or as a filter to remove particulate matter from the vessel effluent which is drawn off from below the settled bed layer. Fluid recirculation aids in the fluidization of the filter medium and allows for intermittent operation with a significant reduction in energy and operating costs. The vessel may be operated as an aerobic bioreactor by recirculating air or as an anaerobic bioreactor by recirculating an inert gas. Rotation of the mixing blade through the filter medium with recirculation of fluids through the mixing blade allows the filter medium to be efficiently backwashed in order to prevent filter plugging.

Title: Tool cases with pivotable holders
Inventor: VASUDEVA KAILASH C
IPC: B25H3/02
Filed: 1999-03-30
Granted: 2008-03-18
Abstract: The case is generally upright, and has at least one item holder rotatably mounted therein, for rotation between a storage position and an access position. In the storage position, each holder is oriented parallel or close to parallel to the main plane of the case, to minimize space requirements. In the access position, each holder is oriented at an angle to the main plane of the case, such that the items angle outwardly from the case for easier access. Where two or more rotatable holders are used in the case, they preferably are ganged together, such that they rotate in unison. With the lid of the case open, or upon opening or removal of the lid, the item holders are able to rotate or be rotated to the access position. In some embodiments, they may rotate to the access position automatically upon opening of the lid, either by gravity or by virtue of a spring. In other embodiments, gravity may keep the holders in the storage position until they are manually moved to the access position, where they may then remain by gravity. In still other embodiments, the holders may be configured to rotate to the access position by gravity or by a spring, but may be prevented from doing so by a releasable catch or by a detent or the like. Once in the access position, the holders may be rotated back to their storage positions and retained there by gravity or a catch or detent or the like, or in some embodiments may only be returned and retained in their storage positions by closing the lid.

Title: Bypass apparatus and method for series connected energy storage devices
Inventor: COMTE CHRISTOPHE
IPC: H01M50/574
Filed: 1998-07-23
Granted: 2007-12-11
Abstract: A bypass apparatus and method for series connected energy storage devices. Each of the energy storage devices coupled to a common series connection has an associated bypass unit connected thereto in parallel. A current bypass unit includes a sensor which is coupled in parallel with an associated energy storage device or cell and senses an energy parameter indicative of an energy state of the cell, such as cell voltage. A  bypass switch is coupled in parallel with the energy storage cell and operable between a non-activated state and an activated state. The bypass switch, when in the non-activated state, is substantially non-conductive with respect to current passing through the energy storage cell and, when in the activated state, provides a bypass current path for passing current to the series connection so as to bypass the associated cell. A controller controls activation of the bypass switch in response to the voltage of the cell deviating from a pre-established voltage setpoint. The controller may be included within the bypass unit or be disposed on a control platform external to the bypass unit. The bypass switch may, when activated, establish a permanent or a temporary bypass current path.

Abstract: A bottom for a paper cup is formed by advancing a punch against a paperboard web to push the web against a cutting edge which cuts out a circular cup bottom blank from the web. The punch is kept in a forward state to clamp an outer peripheral portion of the blank immovably against a surfac e of a sleeve. A reciprocable draw is advanced against a center portion of the blank to push the center portion into a circular opening of the sleeve while maintaining the clamping force, to cause the center portion of the blank to become stretched. The clamping force is then progressively released to permi t the outer peripheral portion to enter the opening and become bent to form a lip extending at a substantially right angle. The lip is compressed within a gap formed between the draw and a surface of the opening. Because of the stretching of the blank, pleats formed in the lip are only in the form of micropleats that are flattened in a non-folded over state.
