Abstract: A forage bale dryer and method of operation is described, which is particularly adapted to dry large bales of forage material, such as hay, alfalfa, etc. The dryer has a bale support platform disposed between a lower and an upper plenum chamber, and the upper plenum chamber is spaced from the support platform to define an accessible stacking area for disposing one or more layers of forage bales onto the support platform. An air circulating passage is connected to the plenum chambers to direct a drying air flow there across. A sheet of flexible film material is disposed about the stack of bales and between the plenum chambers, whereby upon the application of a drying air flow, a negative pressure causes the flexible film material to collapse against the circumferential side surface of the stack of bales, whereby the drying air flow is confined through the stack. The drying air flow is also reversible by proper synchronization of valve plates in the air circulating conduits. The bidirectional airflow allows to achieve more uniform drying throughout the bales.

Title: Pressure gage and switch
Inventor: PALMER BRIAN L
IPC: G01L7/08
Filed: 2004-05-27
Abstract: A pressure gage adapted to provide a mechanical indication of a sensed pressure and to provide an electrical signal indicative of the sensed pressure. The pressure gage includes a housing having a first fluid pressure chamber, a second fluid pressure chamber, and flexible diaphragm separating the first fluid pressure chamber from the second fluid pressure chamber. A magnet is coupled to the diaphragm such that movement of the diaphragm causes a related movement of the magnet. A helix is located adjacent to the magnet and a pointer is attached to the helix for conjoint rotation with a helix about a rotational axis. A Hall effect sensor is also located adjacent the magnet. Movement of the magnet in response to movement of the diaphragm rotates the helix and the pointer to provide a mechanical indication of the pressure sensed by the diaphragm, and the movement of the magnet causes the Hall effect sensor to generate an electrical signal indicative of the pressure sensed by the diaphragm.

Abstract: The present generally relates to apparatus and methods for instrumentation associated with a downhole deployment valve or a separate instrumentation sub. In one aspect, a DDV in a casing string is closed in order to isolate an upper section of a wellbore from a lower section. Thereafter, a pressure differential above and below the closed valve is measured by downhole instrumentation to facilitate the opening of the valve. In another aspect, the instrumentation in the DDV includes sensors placed above and below a flapper portion of the valve. The pressure differential is communicated to the surface of the well for use in determining what amount of pressurization is needed in the upper portion to safely and effectively open the valve. Additionally, instrumentation associated with the DDV can include pressure, temperature, seismic, acoustic, and proximity sensors to facilitate the use of not only the DDV but also telemetry tools.

Abstract: La présente invention concerne l'agrégation de cellules souches embryoniques et de corps embryoïdes (EBs), identifiée comme cause de la difficulté de génération de grandes quantités de tissus cellulaires dérivés de cellules souches embryoniques (ES). Pour y remédier, l'invention propose un nouveau bioprocessus dans lequel l'agrégation de cellules formant des sphéroïdes, par exemple des cellules souches embryoniques et des sphéroïdes, comme les Ebs, est contrôlée, par exemple par encapsulation dans une matrice. Des Ebs peuvent ainsi être générés de manière très efficace et mis en culture dans des systèmes de brassage à haute densité cellulaire. Les conditions de brassage facilitent la mesure et le réglage des conditions de masse, et permettent d'utiliser des systèmes à bioréacteurs échelonnables pour la production clinique de tissus. L'invention permet ainsi la génération de tissus dérivés de cellules ES à échelle clinique. L'invention concerne également tout type de cellules formant des sphéroïdes et d'autres types de cellules multipotentes.

Title: Fuel cell
Inventor: SANO SEIJI
IPC: H01M8/04
Filed: 2003-01-28
Abstract: In a fuel cell, a porous portion (32) is formed in a separator. At a surface of the porous portion opposite to a surface where a reactant gas passage is formed, a cooling gas passage (33) is formed. The cooling gas passage (33) may be fluidly connected to a reactant gas supply passage for supplying reactant gas to the fuel cell. The cooling gas passage (33) is controllable in flow amount. The porous portion (32) is formed only in a separator portion where a downstream portion of the reactant gas passage (27, 28) is located. At a separator portion where an upstream portion of the reactant gas passage (27, 28) is located, a coolant passage (26) is formed. A rib and a rib-bottom portion have a great porosity. A groove may be filled with porous material (49). The porous portion may be replaced by a water exchange portion (32').  A portion of the separator other than the region of the porous portion may be made by porous material (51). Due to these, a fuel cell can be obtained where removal of product water is improved, product water can be utilized for humidifying gas, and product water can be uniformly removed.
