  • Patent number: 10357788
    Abstract: A rotor is mounted in a stationary casing of a centrifugal separator. An electrical rotation sensor with a first electric coil mounted on the rotor and a second electric coil, connectable to a power source and mounted on the casing, is provided. A processor associated with the second coil detects voltage oscillation induced in the second coil when the rotor rotates to calculate and display rotor speed. The first coil is connected in a circuit including electrodes exposed to the interior of the rotor at a predetermined position. The voltage across the second coil changes when the electrodes are contacted by accumulated material in the interior of the rotor. This change is detected to provide an indication that cleaning of the rotor is required. A permanent magnet is mounted on the rotor and causes automatic charging of the battery via the stator coil when the rotor rotates.

  • Publication number: 20150005149
    Abstract: Centrifuges are useful to, among other things, remove red blood cells from whole blood and retain platelets and other factors in a reduced volume of plasma. Platelet rich plasma (PRP) and or platelet poor plasma (PPP) can be obtained rapidly and is ready for immediate injection into the host. Embodiments may include valves, operated manually or automatically, to open ports that discharge the excess red blood cells and the excess plasma into separate receivers while retaining the platelets and other factors in the centrifuge chamber. High speeds used allow simple and small embodiments to be used at the patient's side during surgical procedures. The embodiments can also be used for the separation of liquids or slurries in other fields such as, for example, the separation of pigments or lubricants.

  • Patent number: 8894559
    Abstract: The spinning disc centrifuge rotor includes a sample holder formed from a cylindrical disc body and a cover plate that are made from a transparent material, such as polycarbonate. The disc-shaped body has two concentric or coaxial recesses defined therein. The first recess forms a cylindrical well or sample chamber for receiving a generally cylindrical rock sample. The second recess has a larger diameter than the first recess, and is shallower, forming a fluid collection area above the sample well, the second recess forming an annular ring extending around the top edge or rim of the sample well. An O-ring snugly within the outer wall of the second recess and forms a seal between the cover plate and the floor of the second recess, preventing fluid leakage. A rotor shaft extends from the bottom face of the cylindrical disc.

  • Patent number: 8852069
    Abstract: A centrifuge includes a vacuum pump machine configured of an auxiliary vacuum pump and an oil diffusion pump for exhausting gas inside a rotary chamber to outside, in which a rotor rotates at high speed. In the centrifuge, a thermistor for detecting a temperature of oil and an oil surface inside a boiler of the oil diffusion pump is provided inside the boiler, and power of a heater is adjusted with the temperature detected by the thermistor, so that a degree of vacuum inside the rotary chamber is stably reduced from atmospheric pressure to a high vacuum state. Besides, when the heater does not heat, a current is carried through the thermistor for self-heating, and it is determined from variation in a resistance value whether the oil exists or not at a position at which the thermistor 8 is placed.

  • Patent number: 8840535
    Abstract: Method and apparatus for centrifugal blood component separation including temperature sensing in each of a plurality of separation cells. The temperature of unit of bloods over time is recorded. If the temperature of any of the units exceeds a pre-determined maximum, portions of the blood separation device may be cooled. A controller may determine which of the units to process first, generally proceeding from the warmest unit to the coolest. The order of unit processing may be changed during processing. The detected temperature may be used to calibrate a pressure sensor used to predict the volume of a component separated from a composite fluid by predicting the volume of the composite fluid from sensed pressure and predicting the volume of other separated components from sensed movement of the other components to collection bags.

    Abstract: A torque sensing device capable of measuring the force exerted by a torque arm on a lever is positioned between the torque arm and the lever. The torque arm is connected to the pinion of a planetary gearbox for rotating the bowl and screw conveyer of a decanter centrifuge at different speeds. The torque sensing device measures the torque between the pinion gear and the planetary gearbox. The sensor can be connected to a controller which can reduce the flow of the liquid/solid mixture to the decanter centrifuge thereby/reducing the torque and avoiding substantial damage to the planetary gearbox.
