Container and a device for indirectly cooling materials and method for producing the container

Номер: US20120264582A1
Принадлежит: Eppendorf SE

The present relates to a container and to a device for indirect material cooling and to a method for producing the container according to the invention. Through the present invention a much more efficient indirect heat transfer is facilitated from the exterior of the container into the interior of the container. The improvement of the heat conductivity and of the heat transfer of centrifuge containers yields a reduction of the necessary power of the refrigeration system for cooled centrifuges. Through the higher performance of the centrifuge a higher speed can be run for identical centrifuge temperatures and/or at the same centrifuge temperature and speed, the input power of the refrigeration unit can be reduced.

Blood Processing Apparatus with Robust Automated Process Control

Номер: US20130072367A1
Принадлежит: TERUMO BCT, INC.

A centrifuge for separating blood having a camera observing fluid flow, and a controller controlling the flow. The location of an interface is detected by image processing steps, which may comprise the steps of “spoiling” the image, “diffusing” the image, “edge detection”, “edge linking”, “region-based confirmation”, and “interface calculation”. “Spoiling” reduces the number of pixels to be examined preferentially on orthogonal axis oriented with respect to the expected location of the interface or phase boundary. “Diffusing” smoothes out small oscillations in the interface boundary, making to the location of the interface more distinct. “Edge detection” computes the rate of change in pixel intensity. “Edge linking” connects adjacent maxima. “Region-based confirmation” creates a pseudo image of the regions that qualify as distinct. “Final edge calculation” uses the points where the shade changes in the pseudo image, averages the radial displacement of these points for the interface position. 1. A centrifuge blood processing system for separating fluid components comprising:a separation chamber rotating about a central rotation axis,at least one pump regulating fluid flow in said separation chamber;a light source in optical communication with said density centrifuge blood processing system for providing an incident light beam for illuminating an observation region on said density centrifuge blood processing system, thereby generating light transmitted, scattered or both from said observation region;a light collection element in optical communication with said density centrifuge blood processing system for collecting at least a portion of said light transmitted, scattered or both from said observation region and for directing at least a portion of said light transmitted, scattered or both from said observation region onto a two-dimensional detector;the two-dimensional detector positioned to receive and detect said light transmitted, scattered or both from said ...

Принадлежит: Seven Juice Co Ltd

A centrifugal filtering device includes a centrifugal drum and a rotary filter. The centrifugal drum has a receiving space for accommodating the source fluid. The rotary filter rotatably mounted in the receiving space includes a filter body and a filtrate discharge pipe. The filter body includes a filter cartridge defining a filtrate-collecting space. The filtrate discharge pipe connecting the filter body is communicative in space with the filtrate-collecting space. By rotating at least one of the centrifugal drum and the rotary filter, the source fluid is driven to generate a vortex by a centrifugal force. The centrifugal force drives the source fluid to form a heavy-phase fluid hitting the centrifugal drum and a light-phase fluid approaching the filter cartridge. The light-phase fluid passes the filter cartridge and then reaches the filtrate-collecting space as a filtrate, and the filtrate is exhausted via the filtrate discharge pipe of the centrifugal filtering device.

A horizontal centrifuge, method and system of use, recovers weighting materials from a returned drilling fluid slurry. A clean fluid is delivered, through a clean fluid pipe arranged axially at the hub, to solids discharge ports. The clean fluid is directed radially and circumferentially outwardly at the discharge ports for mixing homogeneously with the recovered weighting materials from forming a reconstituted weighted drilling mud. The reconstituted weighted drilling mud can then be delivered to a rig mud tank for use in a drilling operation. In the system, a drilling fluid and low gravity solids, which are separated from the weighting materials in the horizontal centrifuge, being a first centrifuge, are directed to a second centrifuge which is capable of removing the low gravity solids, thereby producing a clean fluid. The clean fluid is recycled to the first centrifuge for delivery through the clean fluid pipe.

A centrifuge and a method for preventing ignition of combustible temperature-control media in centrifuges after a crash of the centrifuge rotor are presented. It is monitored whether the pressure in the evaporator lies below a specified minimum pressure and/or above a specified maximum pressure. Measures to prevent ignition of the temperature-control medium can be taken in a targeted manner. In the event that the pressure lies below a minimum pressure, it must be assumed that either a leak or a crash is present, wherein a leak leads to a slow release of combustible temperature-control medium and a crash leads to an sudden release of combustible temperature-control medium. If the pressure lies above a maximum pressure, there is a risk that there is a large amount of combustible temperature-control medium in the evaporator which could be ignited in the event of a crash. 113.-.

ROTOR FOR A LABORATORY CENTRIFUGE

Номер: US20140349829A1
Принадлежит: SIGMA LABORZENTRIFUGEN GMBH

A rotor body () for a laboratory centrifuge includes a rotor hub () which is inserted in a central opening and on the outside of which, at least one helically curve continuous groove () runs so as to form a transport facility for cooling air. The cooling air is effective in the direction of the axis () of the rotor hub () between the upper side () and the underside () of the rotor (). In this manner, a cooling airstream which runs axially through the rotor () and undergoes direct thermal exchange with the rotor () and the mixtures to be treated in the laboratory centrifuge can be realized. No additional installation volume is required for this measure and equalization of the temperature of the rotor and the housing accommodating the rotor can be achieved. 110-. (canceled)11. A rotor for a laboratory centrifuge , comprising:a rotor body having a central opening;a plurality of holders provided in a peripheral area of said rotor body, wherein said holders are configured to contain a substance mixture for treatment by centrifuging;a rotor hub inserted in the central opening of the rotor body;at least one helically winding, uninterrupted groove formed in an outer side of the rotor hub, thereby forming a feed device effective in a direction of an axis of the rotor in the manner of an axial fluid work machine between an upper side and lower side of the rotor.12. The rotor according to claim 11 , wherein the rotor hub consists of an annular flange configured to lie flush with an underside rim of the opening and a hollow claim 11 , cylindrical attachment element that is inserted into the opening claim 11 , wherein the at least one groove extends between an upper end face of the attachment element and an lower end face of the annular flange.13. The rotor according to claim 11 , wherein a pitch of the at least one groove is set depending on a direction of rotation of the rotor claim 11 , such that the feed device has an axial direction of feed from the upper side of the rotor ...
