Abstract: A centrifuge system includes a drive shaft bearing mounted to a drive shaft for engaging a solenoid actuated plunger in low friction contact over a predetermined angular velocity range of the drive shaft. The drive shaft bearing includes a frustoconical bearing surface that contacts a plunger bearing mounted in an end of the plunger when the solenoid actuates the plunger. The frustoconical bearing surface transforms vibrations of the drive shaft transverse to its axis of rotation into linear motion of the plunger relative to the drive shaft. The plunger is mounted inside the solenoid such that the solenoid, the plunger and the drive shaft are substantially concentric. The plunger is movable in the solenoid in response to application of an appropriate electrical current to the solenoid. However, the plunger fits sufficiently close within the solenoid that the force movement of the plunger arising from contact with the vibrating drive shaft bearing is damped by friction between the solenoid and the plunger.

Abstract: The solid jacket centrifuge is a plural chamber centrifuge (1). A housing (2) is, together with the centrifuge, stationarily supported, noting that a carrier (6) for cylindrical mantle surfaces (7 and 8) is provided within the housing (2). The cylindrical mantle surfaces (7 and 8) delimit annular chambers (9 and 10) and are shiftable in the direction of the axis of the shaft (3). There is further provided a screw conveyor (12) for introducing the material to be dewatered. The material to be dewatered enters the first annular chamber (9) via radial channels (15). By shifting the cylindrical mantle surface (7) in the axial direction, the material is discharged in a radial direction into the concentric greater annular chamber (10). When subsequently the mantle surface (8) is moved in the axial direction, discharge is again effected in the radial direction.

Abstract: A batch-type centrifugal system utilizes a gimbal-like suspension at the end of a rotating shaft distal an attached bowl at the other end of the shaft. The shaft rotates within an elongated bearing which is supported proximal the bowl by a support which is selectively variable in resiliency. This variation in resiliency changes the natural radial frequency of the system whereby operation of the system at rotational speeds which correspond to the natural radial frequency may be minimized, thereby effecting smooth loading, drying, and unloading operations.

Abstract: The drive shaft assembly for a centrifuge includes a resilient damper member mounted between a flexible shaft element and a bearing shaft element for rotation therewith. Vibrations imposed on the flexible shaft element by a centrifuge rotor are damped by the resilient damper member.

Abstract: An arrangement for balancing a centrifuge rotor during operation comprises means (5, 8) forming an annular channel (11) which concentrically surrounds the rotational axis of the rotor and in which there are arranged three separately movable balancing bodies (12). The annular channel (11) is partly defined by a slide (8) movable axially by control means (9, 14-17) to and from contact with the balancing bodies (12) for arresting and releasing them in the channel during the rotor operation.

Abstract: In a suspension system for a gyrocompass or similar device, a plurality of sway rods, springs and shock snubbers are combined to isolate the gyrocompass or similar device from vibrations having low frequencies in all directions.

Abstract: Resilient high-speed rotor support, especially applicable to rotor shafts open-end spinning machines. The support is made up of a double-row rolling bearing, a rotor shaft, and a central sleeve for the bearing, as well as resilient damping elements disposed at the ends of the central sleeve and fixed within the housing of the spinning mechanism. At the stepped ends of the central sleeve there are fixed resilient damping elements by means of their radially inner annular parts, the external circumference of the damping elements, reduced by the height of the limiting gap between them and the housing, extends to the circumference of marginal orifices within the housing. The bore at the rotor end of the central sleeve is formed with a tolerance to provide a running fit with the rotor hub. The support of the invention is applicable especially in spinning machines operating with rotor speeds exceeding 60,000 RPM.

Abstract: A suspension system for a rotor includes a coupling having a rigid shaft portion flexibly linked at two connection points to the rotor and to a drive spindle therefor.

Abstract: Balancing bosses integrally forged in a centrifuge rotor. The plurality of balancing bosses in the rotor establish noncritical areas in the rotor for machining to accomplish the precise balancing necessary for high speed ultracentrifugation. The balancing bosses are located away from the high stress periphery of the rotor so that machining a portion of the bosses for balancing purposes will not degrade the integral strength of the rotor.

Abstract: A two plane self-balancing centrifuge is disclosed herein in which the centrifuge rotor is driven by a shaft attached to bearings. The bearings are supported by upper and lower flexible bearing mounts. This results in two horizontally flexible bearing mounting planes to provide a greater degree of freedom for the axis of rotation of the rotor to move into a coincident relationship with the angular momentum vector of the rotor as it changes with dynamic imbalance thereby to compensate for any imbalance which may occur in the centrifuge rotor during processing. The centrifuge particularly suited for use in processing blood.

Abstract: At a centrifugal separator (21), where separated sediment is thrown out in jets (26) from the rotor (22) of the separator through a determined number of nozzles (1, 2, 3) a sensing means (28) is arranged to be influenced by the respective jet and give off a signal (U), which is a measure of a quantity, e.g. the flow, of the medium of the jet, which signals (U) are given off to an apparatus (38), which is arranged to record the signals (U) and in its turn give off a signal (39, 39A, 39B, 39C), if said quantity of the medium in one or more jets is changed, e.g. if the flow through a nozzle ceases by the nozzle having been blocked or if the flow through a nozzle has increased by the nozzle having been eroded.
