摘要： A multi-compartment centrifuge rotor having a sealing element which automatically controls in response to the centrifugation operation the fluid communication between the separate chambers within the rotor. The sealing element is situated within the rotor above an annular and an inner chamber used for containing a fluid mixture. When the rotor is assembled and stationary, the sealing element establishes a seal between the respective chambers. During the rotation of the rotor, centrifugal forces exerted directly on the sealing member cause it to move and release the seal between the respective chambers to allow fluid communication between the chambers. As the rotor returns to a stationary position and the centrifugal forces induced on the sealing member subside, the sealing element automatically re-establishes the seal between the respective chambers.

摘要： The invention is an improved form of an ultracentrifuge used in the separation of gases, particularly those of high molecular weight. Through the introduction of an inner cylinder within the outer cylinder of a high speed centrifuge, a higher over-all flow profile efficiency is created. In addition, although a gain of lesser significance, the vacuum core present in ultra centrifuges, which does not contribute to the separative power of the centrifuge, is virtually eliminated. Moreover, for those gases in which the maximum pressure in the centrifuge is limited by a phase change, i.e. the maximum pressure in the centrifuge must be kept below the vapor pressure, the addition of the inner cylinder raises the pressure in the central core region by several orders of magnitude, which permits the subsequent reduction of pressure on the outer walls of both inner and outer cylinders without any portion of the centrifuge being in the Knudsen regime. With this reduction of pressure on the outer walls, the gas can then be centrifuged at a lower temperature, thus further increasing the productive capacity of such a device.
摘要翻译：本发明是用于分离气体，特别是高分子量气体的超离心机的改进形式。通过在高速离心机的外筒内引入内筒，产生更高的全部流量分布效率。另外，虽然增益不大，但真正消除了离心机分离功率无效的超离心机中存在的真空芯。此外，对于其中离心机中的最大压力受相变限制的那些气体，即离心机中的最大压力必须保持在蒸气压以下，则内筒的加入会使中心芯区域中的压力升高几个数量级，这允许随后减小内部和外部气缸的外壁上的压力，而没有离心机的任何部分都在Knudsen状态。随着外壁上压力的降低，气体可以在较低的温度下离心，从而进一步提高了这种装置的生产能力。

摘要： Apparatus for removing the solid particles from a liquid in which a bowl of generally inverted cup shape is rotated about a vertical axis concurrently with the supply of a liquid containing solid particles to the inner surface of the bowl so that the solid particles are centrifugally forced against the inner surface of the bowl and retained thereon. The bowl has fluid outlet openings in its top wall which extend radially outwardly from the axis of rotation of the bowl a distance greater than the spacing of the lower edge of the bowl from the axis of rotation so that fluid with the solid particles removed therefrom will flow out the outlet openings. Blades, positioned within the bowl so that they have scraping edges located adjacent the bowl inner surface, are mounted independently of the bowl for rotation about the same vertical axis on which the bowl is rotated and normally rotate with the bowl. When the blades are braked, the blades scrape the solid particles off the inner surface of the bowl so that the particles can fall out of the bowl through the lower open end.

摘要： An intermediate speed, continuous flow, high capacity liquid centrifuge assembly characterized by a low pressure drop in the process liquid is described. The elongated, vertically oriented rotor contains a central, generally cylindrical core having radially projecting vanes defining a segmented annular cavity between the core and rotor wall. Hollow shafts support the rotor while providing axial inlet and outlet passageways for continuous flow of process liquid through the rotor during operation. Improved design of flow passages from the axial inlet passageway to respective sectors in the segmented annular cavity and from those sectors to the axial outlet passageway provides a significant reduction in pressure drops through the centrifuge.

摘要： A centrifuge of the type having an internal helical screw conveyor within the centrifuge bowl, and which is subjected to a high internal gaseous pressure, is provided with a lubricating and sealing arrangement for lubricating the conveyor bearings, i.e., the bearings located between the centrifuge bowl and the conveyor. This arrangement includes a rotatable reservoir chamber located within the conveyor, which contains a reserve supply of lubricant, the lubricant being supplied via a passageway to the bearing cavity during operation of the centrifuge via the action of centrifugal force upon the lubricant supply. The chamber includes a flexible wall which is subjected to the internal gaseous pressure, thus transmitting this pressure throughout the lubricant to the bearing cavity. The bearing seals are subjected directly to the gaseous pressure on the exterior surfaces thereof, while the gaseous pressure is transmitted to the internal surfaces thereof via the flexible wall and lubricant. Thus, the pressure is substantially equalized on opposite sides of the bearing seals which results in better sealing. In addition, a collection chamber is provided to collect the total volume of lubricant within the reservoir chamber which will eventually leak past the bearing seals.
摘要翻译：在离心机碗内具有内螺旋输送机并且经受高内部气体压力的类型的离心机设置有用于润滑输送机轴承的润滑和密封装置，即位于离心机碗之间的轴承和输送机。这种布置包括位于输送机内的可旋转的储存室，其包含润滑剂的备用供应源，在通过离心力作用在润滑剂供应时离心机的操作期间，润滑剂经由通道被供给至轴承腔。该室包括受到内部气体压力的柔性壁，从而将该压力通过润滑剂传递到轴承腔。轴承密封件直接承受其外表面上的气体压力，同时气体压力经由柔性壁和润滑剂传递到其内表面。因此，压力在轴承密封件的相对侧基本相等，这导致更好的密封。此外，设置收集室以收集储存室内的润滑剂的总体积，其最终将通过轴承密封件泄漏。

摘要： An apparatus for automatically performing a series of operations on a blood sample contained in a vial. For example, in performing the Coombs antiglobulin test, the apparatus is programed to initially inject saline into the vial, to centrifuge the vial at approximately 1,300 RCF, and then to decant the saline from the vial leaving a ''''button'''' of blood cells in the vial. The above sequence is repeated three times, and then a predetermined amount of Coombs serum is injected into the vial. The vial is then agitated to mix the serum with the blood cells, and then it is centrifuged at 500 RCF. At the termination of the centrifuging operation, the sample will be ready for final analysis by a technician. In carrying out this invention, a circular turntable is provided having a plurality of receptacles positioned about its outer periphery. Each of the receptacles is adapted to receive a single vial and includes a pivotally mounted flag which is lifted to a horizontal position whenever a vial is present. An electrical motor is provided to rotate the turntable, and a dispensing mechanism overlies the periphery of the turntable and includes a nozzle for injecting the saline as well as a nozzle for injecting the Coombs serum downwardly into the vial. A photoelectric mechanism is provided for detecting a horizontal flag which then actuates the appropriate injection mechanism. The Coombs injecting mechanism includes a removable cartridge containing the serum. The cartridge comprises a tubular barrel which is closed at its forward end by a nozzle and at its rear end by a cylindrical piston positioned within the bore of the barrel. The mechanism further includes a plunger for driving the piston into the bore of the barrel to dispense the liquid from the forward nozzle.
