A method of expanding tobacco involves introducing a steam flow and a tobacco material into a duct having an inlet and an outlet and defining an arcuate flow path. The tobacco is entrained in the steam flow and conveyed along the arcuate flow path and toward the outlet. The presence of the steam results in volumetric expansion of the tobacco as the steam and entrained tobacco travel along the flow path. The steam and entrained tobacco are then collected and separated. As such, an expanded tobacco is provided.

A method and device for rapidly changing at least one of the temperature and the state of a liquid in a container is provided. The container is rapidly rotated about its longitudinal axis. A source of a thin film of a medium having a different temperature than the liquid in the container is provided to thermally affect the container while rotating the container. The container is positioned at an angle to the horizontal of less than 45°, and the position of the container with respect to the thin film source is controlled by angling the axis of the container skewed from the axis of the rotating mechanism. The device can be used to cool liquids such as beverages, warm liquids such as infant formula, and/or make ice cream.

A catheter comprises an outer shaft and an inner shaft defining a balloon inflation lumen for transport of an inflation fluid therethrough. The expandable balloon has a proximal waist portion and a distal waist portion with a body portion there between. The balloon is engaged to a distal region of the outer shaft and defines an exterior and an interior where the interior is in fluid communication with the balloon inflation lumen. The inner shaft has an inner shaft wall defining a guidewire lumen for passage of a guidewire. A distal portion of the inner shaft is expandable from an unexpanded state to an expanded state such that in the expanded state the guidewire lumen has a greater cross-sectional area than in the unexpanded state.

A fluid spraying gun of the present invention includes: a tube-shape guide, on which a brush extending forward is implanted; a nozzle, which is formed of a flexible pipe member with a front end thereof as a free end, and sprays one portion of gas, which is supplied from the flow separation portion and passes through the nozzle, toward the brush from the front end thereof, while the nozzle undergoes the gyrating motion guided by the tube-shape guide; an inner nozzle, which sprays gas which has passed through a flow rate adjustment portion from a tip portion thereof; and a liquid distribution pipe, which penetrates the tube-shape guide, links an inside of the tube-shape guide with a liquid supply source, has an intermediate portion into which the inner nozzle is inserted in a state where the inner nozzle is directed toward the tube-shape guide, and draws up liquid from the liquid supply source by a negative pressure arising from spraying of gas by the inner nozzle to cause spraying of liquid on the inside of the tube-shape guide. According to the present invention, it is possible to provide a fluid spraying gun in which a liquid with an adequate flow rate can be mixed with a gas, converted into minute drops and sprayed.

Methods for obtaining purified populations of megakaryocytes and platelets by ex vivo culture of stem cells are provided herein.

A conveyance system E for wafers W includes a host computer 1 for carrying out the management of the production of semiconductor devices, a plurality of probers 2 for inspecting the electric characteristics of the wafers W under the administration of the host computer 1, an AGV 3 for automatically transporting the wafers W in block of a carrier in order to deliver the wafers W one by one to these probers 2 according to respective demands and an AGV controller 4 for controlling the operation of the AGV 3 under the administration of the host computer 1.

An error detection and flow rate monitoring system of a liquid fertilizer distribution system of an agricultural implement that can provide feedback to identify compromised flow states in the system and corresponding locations of potential blockage or component failure. The system may include pressure sensors that may be evaluated in pairs or otherwise analyzed comparatively to determine flow rate or other characteristics through nozzle assemblies. The pressure sensors may be mounted in the wet boom between the rows. A control system compares the pressure values before and after each row to determine the pressure drop across its nozzle assembly and may further use the pressure drop values to determine flow or application rates and corresponding errors in the pressure drop, flow rate, and application rate compared to their acceptable values and may provide feedback to identify a specific location(s) of potential blockage or flow-control component failure.

A continuous, semi-continuous or fed-batch mixing apparatus and process for producing and maintaining a consistently mixed substance uses a tubular vessel equipped with a plurality of annular baffles configured to initiate and maintain uniform mixing and efficient dispersion of the substance in the tubular vessel, with a pump to impart unidirectional linear and non-oscillatory motion to the substance in the tubular vessel thereby promoting and maintaining uniform mixing and efficient dispersion of the substance.

The invention relates to a LED cooling system that effects cooling of the LED's during use, and helps the LED's have a longer operating function, and uses less electricity for the LED's to operate. The use of cooling also provides a steadier light and has greater efficiency.

A mountable type microwave oven including a blower fan assembly installed at a rear-upper portion of a cabinet to cool a machine room and ventilate a cooking chamber. The microwave oven includes a cabinet mounted on a wall of a cooking space, or under a storage cabinet, and having a cooking chamber to cook food therein and a machine room to house a plurality of electrical components, which are isolated from each other, an exhaust path to exhaust contaminated air generated from a cooking appliance installed below the wall-mounted microwave oven, a cooling-ventilation path to cool the machine room and to ventilate the cooking chamber, and a blower fan assembly including a drive motor having a pair of shafts to generate a rotating force, an exhaust fan joined to one shaft of the drive motor to generate a suction force and a propulsive force to cause the contaminated air to flow along the exhaust path, and a cooling-ventilation fan joined to the other shaft of the drive motor to generate suction and propulsive forces to cause air to flow along the cooling-ventilation path. Since the cooling-ventilation fan performs cooling of the machine room and ventilation of the cooking chamber, there is no need to provide an additional blower fan. Thus, the number of components of the microwave oven is reduced, thereby reducing production costs and improving productivity.

An aeronautical engine including a fuel pumping device including a high pressure fuel pump including an inlet connected to a low pressure fuel conduit and an outlet connected to a main circuit for feeding high pressure fuel, an electric device starting the engine, and a device cooling the electric starting device connected to the pumping device to ensure cooling by circulation of fuel. The cooling device is supplied with fuel by a pump that includes an inlet connected to the pumping device, upstream from the high pressure pump, and that is driven by an electric motor independently of the high pressure pump.
