Patent number: 7727387Abstract: A pool skimmer to operate independently of a pool filter pump. A pool skimmer has a bucket assembly similar to pool skimmers that use the filter pump to create a suction to draw and hold surface floating debris inside the pool skimmer where the debris can be removed from the bucket assembly and emptied. However, instead of using the pool filter pump, a sealed electrical pump assembly uses a rotatable magnetic assembly inside the sealed pump body. A magnetic impeller fits within the pump body and rotates in response to rotation of the magnetic assembly inside the sealed pump body. This creates a water flow forcing water out of the bucket assembly in contrast to using a filter pump to suck water through the bucket assembly as in conventional technology. Because each pool skimmer operates independently of others and of the filter pump, they may be located without regard to filter pump efficiencies. Moreover, the suction created is not enough to create a health hazard for users, especially small children.Type: GrantFiled: September 19, 2006Date of Patent: June 1, 2010Inventor: Christopher M.

Patent number: 7727413Abstract: A method of processing a workpiece in the chamber of a plasma reactor includes introducing a process gas into the chamber, simultaneously (a) capacitively coupling VHF plasma source power into a process region of the chamber that overlies the wafer, and (b) inductively coupling RF plasma source power into the process region, and controlling plasma ion density by controlling the effective frequency of the VHF source power. In a preferred embodiment, the step of coupling VHF source power is performed by coupling VHF source power from different generators having different VHF frequencies, and the step of controlling the effective frequency is performed by controlling the ratio of power coupled by the different generators.Type: GrantFiled: April 24, 2006Date of Patent: June 1, 2010Assignee: Applied Materials, Inc.Inventors: Alexander Paterson, Valentin N.

Patent number: 7727414Abstract: A heat transfer fluid with carbon nanocapsules. The heat transfer fluid comprises a fluid and a plurality of carbon nanocapsules, uniformly dispersed in the fluid, in an amount of 0.05 to 10 parts by weight, based on 100 parts by weight of the heat transfer fluid. Particularly, the carbon nanocapsules are modified to bond with at least one kind of functional group, improving dispersiblity in the fluid. Thus, since the carbon nanocapsules are apt to disperse in fluid and have superior thermal conductivity, the heat conduction capability of the heat transfer fluid therewith is enhanced.Type: GrantFiled: June 23, 2006Date of Patent: June 1, 2010Assignee: Industrial Technology Research InstituteInventor: Gan-Lin Hwang

Patent number: 7727419Abstract: The invention provides methods and systems for catalytic reforming of a hydrocarbon fuel to produce hydrogen, which may be used as a power source for a fuel cell. In some embodiments, hydrogen is produced by partial oxidation or autothermal reforming of fuel in an oxygen containing gas stream that is rich the majority of the time, with periodic conversion to a lean gas stream for short periods of time to maintain catalytic activity. In one embodiment, hydrogen peroxide is used as the oxidant in an autothermal reforming process. In some embodiments, hydrogen is produced by steam reforming at a low steam to carbon ratio, with a periodic increase in the steam to carbon ratio for short periods of time to maintain catalytic activity.Type: GrantFiled: June 22, 2006Date of Patent: June 1, 2010Assignee: Eaton CorporationInventors: Ralph A.
