摘要:
A vial-based system and method for handling and processing specimens of particulate matter-containing liquid directly in the vial. A processing assembly (40), which includes a stirrer (45) and a particulate matter separation chamber (46), is releasably coupled to the inside of a vial cover (30). The processing assembly (40) remains with the cover (30) when the vial is opened to insert a specimen therein. Application of an external force to the cover (30) detaches the processing assembly from the cover so that it remains in the vial, for access by automated or manual laboratory equipment, when the cover (30) is discarded. Sealing and drainage features help prevent cross-contamination during specimen processing.
摘要:
The present invention sets forth an implement which enables the user to mix paint, and optionally to perform several other painting related functions. The implement has a perforated paddle with oppositely deflected upper portions to enhance mixing of the paint. The implement may be selectively positionable to either mix paint or to support a paint roller for cleaning. A paint can remover and a paint can rim cleaning device are also incorporated into the implement. A single implement can serve the functions of opening paint cans, stirring paint in a container, cleaning the groove around the lip of a paint can, cleaning a paint roller, and as a spatula to aid in removing paint from a can.

A method and an apparatus for generating gas bubbles, which can generate a large amount of micro gas bubbles having diameters of less than 15 μm, specifically less than 10 μm, in a liquid. The apparatus comprises a tube 2 having a closed end 14 at one end and an open end 15 at the other end, and a rotating bladed wheel 3 installed in the tube 2 and rotating coaxially or substantially coaxially with the tube 2. The rotating bladed wheel 3 has one or more blades 4. The face of each blade 4 is substantially parallel to the axis of a rotating shaft 5 of the rotating bladed wheel 3. Ventilation resistance between the interior of the tube 2 on the side near the closed end 14 and the outside gas is equal to or larger than that of a ventilation port 7 having an inner diameter of 0.36 time an average width d of the blades and a length of 3 mm. At least the open end 15 of the tube 2 and the rotating bladed wheel 3 are immersed in a liquid 20 and the rotating bladed wheel 3 is rotated at a peripheral speed of 5.8 m/sec or higher.
摘要:
A reactor containing a plurality of porous rotors is disclosed. A liquid sprayed in a direction from a rotating axis to the rotors is hit by the porous rotors, creating fine liquid particles, so that a mass transfer takes place between the surfaces of the liquid particles and a gas injected into the reactor, and thus a crystallization reaction is initiated. The crystallization reaction is confined by the amounts of the reactants contained in the liquid particles, and will stop as soon as one of the reactants is consumed, so that the resulting crystals can be controlled in nanometer level. The reactor of the present invention is also suitable for use in a liquid-liquid reaction, wherein two different liquids are separately sprayed in a direction from the rotating axis and hit by the porous rotors, and the resulting fine liquid particles of the two different liquids contact and react with each other, so that ultra fine particles are formed.

The present invention sets forth an implement which enables the user to mix paint, clean the can and can lip, and to clean conventional paint rollers utilizing a hand drill. The implement is selectively adjustable to be configured to mix paint in large and small containers and to support a paint roller for cleaning, thereby being capable of providing several functions. The implement is provided with a paddle member that is perforated and of a geometric form to enhance mixing. A paint can remover and a paint can rim cleaning device are also incorporated into the implement. A single implement serves the six functions of opening paint cans, stirring paint in large or small containers, cleaning the groove around the lip of a paint can, cleaning a paint roller, and as a spatula to aid in removing paint from a can.
摘要:
The present invention relates to a high intensity blending apparatus, particularly for blending operations designed to cause additive materials to become affixed to the surface of base particles. More particularly, the proposed invention relates to an improved blending tool for producing surface modifications to electrophotographic and related toner particles. The tool comprises a shank having riser members at each end, such risers being angled to the axis of the shank between 10 and 16 degrees.

A mixing hoe including an elongated handle and a hoe blade attached to the handle is adapted for mixing material in a walled container. The blade forms a bottom edge, opposing upper edge, and first and second opposing side edges. The upper edge has adjacent edge sections extending outwardly and downwardly, from a central recess or opening in the blade upper edge, to respective first and second side edges. The upper edges are bent backward for creating flow patterns. The first and second side edges extend downwardly and inwardly from the upper edge sections outer extremes to the bottom edge. The edges are sloped and the edge corners are rounded to closely resemble container corner and wall characteristics. The blade is manipulated by a user grasping the handle to position at least one of the five scraping edges (two top, two side and bottom) against the base and walls of the container to scrape away material adhering to the base and walls of the container during mixing.

A food preparation system and method, including a base housing, a container detachably engagable with the base housing in which the container is adapted to receive food products. The system also includes a heater within the base housing and/or the container for converting a liquid into a cooking vapor, and a blade rotatably mounted in the container in which the blade supports the food products during a cooking step and processes the food products during a processing step. The system can also have positioning structure within the base housing and/or the container for positioning the blade in a cooking position during the cooking step, and for positioning the blade in a processing position during the processing step.
摘要:
A motorized mixer for mixing bone cement for use in attachment of prosthetics and method for using the mixer. The mixer comprises a mixing chamber, a liner in the mixing chamber, an impeller within the liner, a motor for driving the impeller and programmable memory mechanics for regulating the operations of the motor. The liner comprises a basket for receiving vials of bone cement catalyst and a mixing bowl for receiving the bone cement powder. Preferably the two are permanently attached to one another. The mixing bowl is also used for mixing the two components together to produce the bone cement. During mixing the mixing bowl is maintained under a vacuum to withdraw fumes from the bone cement and to prevent gases from being mixed into the bone cement. Once mixing is complete, a U-shaped trap door releases the mixed bone cement from the mixing bowl, through a discharge tube and into a bone cement cartridge. By maintaining the interior of the bone cement cartridge under a vacuum, the withdrawal of the bone cement is simplified.
