| 20100062289 | Apparatus and Method for Managing Fluids in a Fuel Cell Stack - A plurality of flow field plate assemblies forms a fuel cell stack. Each flow field plate assembly has a first flow field plate positionable on an anode side of a membrane electrode assembly (MEA) of a first fuel cell, a second flow field plate positionable on a cathode side of an MEA of a second fuel cell, adjacent the first fuel cell. At least one back-feed channel is interposed between the first and second flow field plates. At least a portion of the back-feed channel or a reactant manifold opening formed by the first and second flow field plates has a geometry that forms regions of high and low capillary forces, promoting liquid migration toward regions substantially isolated from a flow of reactants, to prevent water collection and ice formation. The migrated liquid being is purged during a purge of the fuel cell stack after operation. | 03-11-2010 |

| 20100199188 | Auto-discovery of diverse communications devices for alert broadcasting - Methods and systems for communicating messages to target communications devices in a target physical location are disclosed. Network sources are queried for logical locations accessible to the network source. A specification of a physical location associated with each logical location is received. Each logical location specification is stored in a data store in association with the associated physical location specification. A specification of the target physical location is received. Those logical location specifications associated with the target physical location are retrieved from the data store, thereby identifying target logical locations. For each target logical location, at least one of the network sources accessible to that logical location is queried for specifications of communications devices accessible to that logical location, thereby identifying the communications devices in the target physical location. The message is communicated to the target communications devices in the target physical location via at least one of the target logical locations. | 08-05-2010 |

| 20100065795 | SCISSOR JACK - A scissor jack for handling heavy duty work includes four arms hingedly arranged to provide two opposite elbows between a base and a load support, a pair of trunnions, one at each elbow connected by a threaded shaft. One end of the threaded shaft is rotatably engaged in a threaded bush anchored to one elbow on a trunnion to extend beyond the outer corner of the elbow. The jack further includes a movable brace comprising a block slidable on the threaded shaft and carried between a pair of plates which are pivotally secured to the connectors and bent to provide stops for simultaneous location of the arms with spacers on the trunnions to determine the extended position of the jack. | 03-18-2010 |

| 20100025357 | CLOSURE - A deformable composite that composite can be used as a liner in a screw cap or as an interference stopper and which contains one or more film layers to control oxygen permeation characterised in that the inverse of the oxygen permeances of in the individual sections of the deformable composite when added together fall between 300 to 1500 preferably 1250 days.atm/ml. This is calculated using the formula 1/P1+1/P2+1/P3+1/P4 . . . +1/Px=Y Where P is the oxygen permeance of each section of the composite in ml/day 1 to x depicts each individual section of the x sections of the composite Y is between 300 to 1500 preferably 1250 days.atm/ml. In a second aspect the outer closure body is perforated to give the outer body an inverse of the gas permeance less than 300 (days/atm/ml). The formula used is 1/(Pl+Ps) <1/Pob Where P is the oxygen permeance of each section in ml/day I depicts the liner s depicts the seal between the liner and the glass bottle ob depicts outer body. | 02-04-2010 |

| 20110284039 | NOZZLE JET CLEANER FOR DRAINS - A nozzle jet cleaning apparatus for unplugging drains includes an elongate hose having an outside diameter of ΒΌ inch and having sufficient resistance to bending and kinking to permit the hose to be fed into a drain passage. A hose coupler is attached to one end of the hose to permit connection thereof with a household source of pressurized water. A cylindrical metal nozzle is mounted inside an end section of the hose at the other end and has a central axial passage extending to a single front aperture located at a front end of the nozzle. The axial passage is of uniform diameter and its front aperture is located at the end of the hose. During use of this cleaning apparatus, the hose is flexible and able to bend along substantially its entire length. An exemplary version of the hose is made of polyamide with polyester yarn reinforcement. | 11-24-2011 |
