IPC: H01M8/04
Filed: 2003-11-25
Granted: 2013-04-02
Abstract: A fuel cell includes a power generation unit provided with a conduit for an oxidant gas containing at least oxygen, a heat radiation unit connected to the power generation unit so as to radiate heat from the power generation unit, a gas flow means for causing the oxidant gas to flow in the conduit, and a cooling means driven independently from the gas flow means so as to cool the heat radiation unit. By independently controlling the driving of the gas flow means and the cooling means, the fuel cell can be driven in such a manner that the temperature of the power generation unit and the amount of water remaining in the power generation unit are regulated into preferable conditions. Furthermore, it is possible to provide a fuel cell and an electronic apparatus with the same mounted thereon in which power generation can be performed stably and various apparatuses are contained therein in a compact form.

Title: Circuit interrupter including arc fault test and/or ground fault test failure indicator
Inventor: ELMS ROBERT T
IPC: H01H9/50
Filed: 2005-07-20
Granted: 2013-02-05
Abstract: A circuit breaker includes a test circuit having one or two indicators, an arc fault signal generator, and first and second test switches. A first indicator is electrically connected in series with the first test switch. This series combination provides a first alternating current signal to the arc fault signal generator, which provides an arc fault signal to an arc fault trip circuit, in order to trip open separable contacts in response to closure of the first test switch. The series combination of the second test switch and the second indicator provides a second alternating current signal to a ground fault trip circuit, in order to trip in response to closure of the second test switch. The indicators provide a visual indication of failure of the arc fault or ground fault trip circuits to trip in response to closure of the first or second test switches, respectively.

Patent CA-2577441-C (CA)
Inventor: NIKOLAY NIFANTIEV
IPC: A61P35/00
Filed: 2005-07-22
Granted: 2010-09-28
Abstract: A low concentration formulation for hydrophobic photosensitizers (PS) and improved method for photodynamic therapy ("PDT"). It was found that PDT  treatments using the disclosed low concentration formulations provide for more accurate, more efficient and more convenient dosing. It was found that the inventive formulation (1) reduces the time for a therapeutically effective level of photosensitizer to accumulate in diseased tissue and (2) reduces the time for achieving a sufficient ratio of photosensitizer in diseased tissue vs. healthy tissue. As a result, the formulation of the invention reduces the time interval between PS application/administration and irradiation (the drug-light interval or "DLI") and can provide for a "same day" PDT treatment option. The inventive formulation can be used for PDT treatment regimes where photosensitizers are administered in at least one preselected dose, including a low concentration therapy for PDT. In particular, when meta Tetra-Hydroxy-Phenyl Chlorin (m-THPC) is the photosensitizer then a concentration of 0.8 mg/ml to 0.04 mg/ml in a mixture of pure propylene glycol and ethanol in a 3:2 volume ratio accumulates in diseased tissue and differentiates between diseased tissue and normal tissue sufficiently quickly for 'one day' or overnight administration and activation treatment procedures to be possible.

Title: Mass spectrometer
Inventor: BATEMAN ROBERT HAROLD
IPC: H01J49/02
Filed: 2006-06-01
Granted: 2014-07-29
Abstract: A method of mass spectrometry is disclosed wherein voltage signals from an ion detector are analysed. A second differential of each voltage signal is obtained and the start and end times of observed voltage peaks are determined.  The intensity and average time of each voltage peak is then determined and the intensity and time values are stored. An intermediate composite mass spectrum is then formed by combining the intensity and time values which relate to each voltage peak observed from multiple experimental runs. The various pairs of time and intensity data are then integrated to produce a smooth continuum mass spectrum. The continuum mass spectrum may then be further processed by determining the second differential of the continuum mass spectrum. The start and end times of mass peaks observed in the continuum mass spectrum may be determined. The intensity and mass to charge ratio of each mass peak observed in the continuum mass spectrum may then determined. A final discrete mass spectrum comprising just of an intensity value and mass to charge ratio per species of ion may then be displayed or output.

Granted: 2013-04-23
Abstract: A ferric and acid complex includes the reaction product of a chelant, iron oxide, a base, and a reaction promoter. The chelant has at least one carboxylic acid functionality. The reaction promoter has an Fe3+ ion. A  process for preparing the ferric and acid complex in a vessel includes charging solvent, the chelant, the base, the iron oxide, and the reaction promoter into the vessel. The solvent, chelant, base, iron oxide, and reaction promoter are heated to a temperature of at least 170 ~F for a period of at least about 3 hours to form the ferric and acid complex. Due to the use of the reaction promoter having the Fe3+ ion, the process for preparing the ferric and acid complex results in reduced degradation of the chelant during processing and, thus, a high quality ferric and acid complex.

Les cellules transfectées peuvent également être pré-adaptées pour se développer dans un milieu sans sérum, réduisant de manière significative le temps nécessaire pour obtenir la production de protéines dans un milieu sans sérum. Dans certaines méthodes, les cellules pré-adaptées peuvent être utilisées pour la production de protéines suite à la transformation dans des conditions sans sérum. On utilise, de préférence, dans cette méthode, des cellules eucaryotes, et plus préférablement, des cellules mammifères.
