METHOD AND APPARATUS FOR CENTRIFUGAL COMPACTION

Номер: CA1053416A
Принадлежит: KENNAMETAL INC, KENNAMETAL INC.

A method and apparatus for the centrifugal compaction of particulate material in which the particulate material is admixed with a liquid to form a slurry and is then placed in a chamber and centrifuged about a main axis to cause the material to compact into a discrete body. A particular feature of the invention is to be found in the fact that the chamber in which the slurry is contained during compacting is caused to rotate about an axis inclined to the main axis so that the particulate material is agitated and thereby nests intimately together during the centrifuging operation thereby resulting in workpieces significantly more dense than can be arrived at by simple centrifuging or even by pressing.

A concentrator is used for concentrating a fluid, particularly a plasma component out of blood, for treatment of a patient. The concentrator apparatus includes a main housing defining a centrifuge chamber, that also holds the filter. The concentrator allows viewing of the fluid after centrifuging, with an outlet port positionable at a height corresponding to the level of the fraction of the fluid to be further concentrated. Once the fluid is centrifuged, a portion of the fluid is drawn through the outlet, and then pressured past the filter to further concentrate the fluid using the same vessel as used for centrifuging. The same plunger is preferably used to draw centrifuged fluid from the centrifuge chamber as to pressure the centrifuged fluid past the filter.

The specification discloses a device for centrifuging liquids and a means for analysing or processing sets of liquid samples and comprising an aforementioned device. More particularly, it relates to a device for centrifuging liquids containing particles or cells in suspension. The invention provides a liquid-centrifuging device which is free from the need for a vertical axis of rotation. The centrifuging device is characterised in that the vessel for holding the liquid to be centrifuged has a shape and is made of a material such that the liquid therein is kept inside it by the action of electrostatis forces even if the vessel is not rotating and its orifice is facing downwards. As a result, the vessel can be disposed in an invariable position relative to the axis of rotation. This invariable position is the position for centrifuging, i.e. at which the free surface of the liquid in the vessel faces the axis of rotation. The axis of rotation may be in any direction but is preferably horizontal ...

Provisions are made for electronically identifying the maximum allowable speed of an ultracentrifuge rotor for the purpose of supplying the identification information to a rotor overspeed control to prevent spinning a rotor beyond its designed top speed. The top surface of the rotor carries a number of annular bands which may be either black or white. The color of the annular band in each band position is detected by means of an electronic circuit including a light source, a photocell detector, and a transistor switch for each band. Each transistor switch conducts when the annular band from which it receives reflected light is black, but does not conduct when the annular band is white. Each conducting switch puts out a steady voltage signal of different amplitude. The voltage output signals of the transistor switches are added to generate an analog control signal identifying the rotor by the color combination of its annular bands. If there are three annular band positions on the rotor, ...

A fixed-angle rotor for centrifuges includes stiffening ribs on the lower side of its rotor body. Its rotational energy is comparatively low during operation even at high speeds, whereby safety is noticeably increased without the need for a reinforced armored vessel in the centrifuge that is equipped therewith. At the same time, the drive power required to drive the fixed-angle rotor remains low. The fixed-angle rotor also withstands extreme loads over a long period of time. In addition, the fixed-angle rotor can be manufactured cost-effectively, because no additional components are required; rather, the stiffening ribs can also be manufactured during the manufacture of the rotor body. Finally, very thin rotor shells can also be used, which improves the temperature control of the samples, because the fixed-angle rotor has very good structural stability, especially in the main load directions. 1.

Provided herein are devices and methods of processing a sample that include, in several embodiments, rotating one or more microfluidic chips that are mounted on a support plate using a motor driven rotational chuck. By spinning one or more of the microfluidic chips about a common center of rotation in a controlled manner, high flow rates (and high shear forces) are imparted to the sample in a controlled manner. Each microfluidic chip can be rotated 180° on the support plate so that the sample can be run back-and-forth through the microfluidic devices. Because the support plate can be driven at relatively high RPMs, high flow rates are generated within the microfluidic chips. This increases the shear forces on the sample and also decreases the processing time involved as the sample can quickly pass through the shear-inducing features of the microfluidic chip(s). 1173-.

Centrifuge

Номер: US20210138485A1
Принадлежит: Bluecatbio GmbH

The present invention relates to a centrifuge for cleaning a reaction vessel unit, comprising a rotor and a rotor chamber in which the rotor is positioned and supported in rotary fashion. The rotor chamber is delimited by a housing having a drainage channel beneath the rotor. Adjacent to the channel, the inner surface of the housing is embodied in the form of a funnel that feeds into the channel. This centrifuge does not require a suction pump for suctioning liquids from the rotor chamber. In addition, the centrifuge can be provided with an exchangeable module that delimits the rotor chamber and includes the rotor. The exchangeable module can be exchanged after a predetermined amount of use and replaced with another. It is also possible, however, for the module to be removed from the centrifuge, cleaned, and re-inserted.

Автор: John G. Gorman

Coordinated conveyors in an automated system. A system comprises a plurality of conveyors, which each comprise a plurality of segments, and one or more stations. An instruction is received to perform an operation that requires at least one station to process at least a first item held by a first segment of a first conveyor and a second item held by a second segment of a second conveyor. In response to the instruction, one or both of the first and second conveyors are moved, such that the first segment and the second segment are aligned at the station. After alignment, one or more instruments of the station process the first item and the second item.

Devices and methods for plasma separation and storage

Номер: US20210156842A1
Принадлежит: Sandstone Diagnostics Inc

A centrifugal cartridge or disk used for extraction of light supernatant fractions from fluid samples is described, particularly for non-homogenous fluid biological samples such as whole blood. The device may be used to collect cell-free blood plasma or a fraction of whole blood containing target cells such as leukocytes. Single or multiple channels are described, including channels with passive valves, gaskets, receiving cavities, inlet holes, capillary wicking ridges, distal cavities for cell retention, separator gel, and density medium. Centrifugal action causes whole blood in a receiving cavity to pass into one or more channels where it separates into blood cells, plasma and optionally fractions of an intermediate density. After spin, the plasma returns to the receiving cavity by way of the one or more channels for extraction through the inlet hole or other inwardly located hole. Disposable cartridges are constructed of monolithic top and bottom plates, which may be joined together by an elastomeric outer seal.
