摘要:
A polyvinylidene fluoride (PVDF) pyrolyzate adsorbent is described, having utility for storing gases in an adsorbed state, and from which adsorbed gas may be desorbed to supply same for use. The PVDF pyrolyzate adsorbent can be of monolithic unitary form, or in a bead, powder, film, particulate or other finely divided form. The adsorbent is particularly suited for storage and supply of fluorine-containing gases, such as fluorine gas, nitrogen trifluoride, carbo-fluoride gases, and the like. The adsorbent may be utilized in a gas storage and dispensing system, in which the adsorbent is contained in a supply vessel, from which sorbate gas can be selectively dispensed.

Methods and apparatus to receive and discharge bulk materials are disclosed. An example method for treating gaseous fluid includes filling a device with ceramic granular material, a ceramic heat storage body, a catalyst body and a particle-shaped bulk material including calcium and/or carbon. The method also includes supplying gaseous fluid to be treated into a bulk material container and acting upon the bulk material in the bulk material container with the supplied gaseous fluid while discharging the bulk material out of the bulk material receiving apparatus.

A recording apparatus comprises a printer body and an ink nozzle in the interior of the printer body. An opening and closing member is movably affixed to an upper side of the printer body. An external tank is located exterior to the printer body. A liquid supply flow path provides a liquid from the external tank to the ink nozzle. A securing member secures the height and/or the width of the liquid supply flow path. The securing member may be disposed between the opening and closing member and the printer body. The liquid supply flow path may be disposed between the securing member and the printer body.

The present invention relates to microfluidic devices that comprise a 3-D microfluidic network of microchannels of arbitrary complexity and to a method for fabricating such devices. In particular, the invention relates to a method of forming microfluidic devices having 3-D microfluidic networks that contain open or closed loop microchannels using a single-step molding process without the need for layer-by-layer fabrication, and to the resultant microfluidic devices. The networks of such microfluidic devices may comprise one or more microchannel circuits which may be discrete or interconnected.

A method of fueling with compressed gas is described. In one embodiment, the method includes providing a supply of compressed gas; providing a storage tank with a fueling line, and a nozzle in the fueling line, the nozzle movable between at least a flow reduction position and a full fuel flow position; initiating fueling from the supply of compressed gas with the nozzle in the flow reduction position for a predetermined time or until a minimum pressure is obtained; when the predetermined time or the minimum pressure is obtained, moving the nozzle to the full fuel flow position; and fueling the storage tank from the supply of compressed gas with the nozzle in the full fuel flow position until fueling is completed. A vehicle incorporating the nozzle is also disclosed.
摘要:
A method of delivering feed, for example a paraffinic solvent treated bitumen froth, to a separation vessel, for example a froth separation unit (FSU). The feed is delivered from one or more side inlets that may be substantially normal to, and flush with, the wall of the vessel. In contrast to certain conventional feed systems used in gravity separators which use a distributor plate to widely distribute the feed with a vessel, the feed is delivered such that it flows down the inside wall of the vessel. This feed delivery is characterized by a Richardson number of greater than 1.0. Such feed delivery is particularly useful where the feed has particles with a bi-modal size distribution to be separated from an overflow stream. The gentle flow serves to mitigate the upward flux of the smaller particles, for example mineral solids, by being trapped below the larger particles, for example precipitated asphaltene aggregates.

Deployable aerodynamic devices with reduced actuator loads, and related systems and methods are disclosed. An external flow system in accordance with a particular embodiment includes an external flow body, a deployable device carried by and movable relative to the external flow body, and a coupling connected between the external flow body and the deployable device. The system can further include an actuator device operatively coupled between the external flow body and the deployable device, with the actuator device positioned to move the deployable device along a motion path between a stowed position and the deployed position. The motion path can have a first portion over which the load delivered by the actuator device increases as the deployed device moves toward the deployed position, and a second portion over which the load delivered by the actuator device decreases as the deployed device moves toward the deployed position.

To improve operability of a switching operation and locking operation of an operation pattern switching valve for switching the operation pattern of controlling devices for actuator control valves. An operation pattern switching device has a rotating operation member that rotates around a shaft center of a rotating support shaft, and thereby performs a switching operation of the operation pattern switching valve; and an operation lever that is provided rotatably integrally with the rotating operation member and performs a rotating operation of the rotating operation member. The rotating support shaft is, at each pattern switching position of the operation pattern switching valve, in a circumferential direction, provided with a plurality of lock engagement parts each with which the operation lever engages. The operation lever moves in a direction orthogonal to the shaft center of the rotating support shaft, and be thereby made engageable/removable with/from each of the lock engagement parts.

A channel control mechanism for a microchip has a laminated structure formed of members including elastic members, and includes: a sample reservoir for packing a sample therein; a reaction reservoir in which mixture and reaction of the sample are performed; and a channel formed in a middle layer of the laminated structure, for bringing the sample reservoir and the reaction reservoir into communication with each other. The channel control mechanism performs the reaction and analysis in such a manner that the sample is delivered into the reaction reservoir through the channel. A shutter channel (pressurizing channel) is provided in a layer different from a layer in which the channel is formed so that the pressurizing channel partially overlaps the channel. The channel is closed through applying a pressurized medium to the shutter channel (pressurizing channel), and the channel is opened through releasing a pressure of the pressurized medium.
摘要:
The liquid flow rate control apparatus includes a first flow rate control unit which includes a first flow rate control valve for a small flow rate with a first controlled flow rate range, and a second flow rate control unit which includes a second flow rate control valve for a large flow rate with a second controlled flow rate range. In particular, an overlapped range is present between the first and second controlled flow rate ranges and a liquid flows on either any one or both of the first and second flow rate control units depending on variation of a required value of a total rate. The flow rate on any one of the first and second flow rate control units is maintained and the flow rate on the other one increases while increasing the total flow rate of the liquids.
