Patent EP-0368621-A2 (EP)
Inventor: ISHIDA MASAHIKO
IPC: C12M1/26
Filed: 1989-11-07
Abstract: A centrifugal separation method for living cells is disclosed in which a cell containing solution is charged in a rotor chamber confined by a steam pressure-resistant wall. A rotor having septa is disposed in the rotor chamber. The septa are rotated in the same direction at the same angular velocity as the rotor while at least part thereof is immersed in a solution in the rotor when cells are to be centrifuged from the cell-containing solution. After the cells are separated and adhered to the inner surface of the rotor, a supernatant in the rotor is discharged from the rotor. Then a fresh cultivating medium is introduced into the rotor, and the septa and the rotor are rotated at mutually different angular velocities while at least part of the septa is immersed in the fresh medium in the rotor. As a result, the cells are again suspended in the fresh medium.

A second cylinder (142) is mounted so that it is concentric with the first cylinder and both ends are in operative communication with the liquid conduit. A piston is mounted within each cylinder by a common vertically extending piston rod (47) which connects them. The pistons and cylinders have different effective diameters. Relative movement between the pistons and cylinders is effected periodically in order to force liquid from within the cylinders into the conduit and ultimately out the screens to provide backflushing of the screens, which prevents clogging.

Abstract: An image of a subject in a scene formed by a fixed focus lens through a scanning aperture of an electronic flash camera, particularly that of a subject located closer to the lens than the near distance of its lens normal depth of field, has its clarity or sharpness substantially improved by firing the electronic flash during exposure at the smallest possible aperture for optimum subject image sharpness and overall scene exposure. The appropriate aperture to produce such an image is a function of ambient scene brightness and of the IR light from the electronic flash being reflected from a subject within the scene which are determined prior to and/or at the early stages of an exposure interval.

Abstract: In the continuous kraft pulping of comminuted cellulosic fibrous material (e.g. wood chips) to produce paper pulp, viscosity for a given Kappa Number is significantly increased (e.g. at least about 20%) by adding kraft white liquor to the wash recirculation loop (38-40) in a continuous digester (19). Optimum results are obtained when kraft white liquor is also added to a recirculation loop (28-30) at a central portion of the digester, so that the majority of the digester has countercurrent flow between white liquor and cellulosic material. About 5-20% of the total white liquor necessary to effect kraft cooking is introduced in the wash circulation, and about 10-20% is introduced into the central portion recirculation. The temperature in the wash zone is maintained at about 140-175°C.

Abstract: A tuning circuit (18) for tuning an integrated circuit filter, such as a continuous-time MOSFET-C filter (12), is disclosed. The tuning circuit includes a switched-capacitor network (20) having a capacitor (I) which matches the capacitor used in the filter (12) to be tuned. Also included is a transistor (M) which matches the transistor used in the filter. The switched-capacitor network has a effective resistance which is a function of the switching rate of the network. Feedback circuitry is included which produces a control signal used to vary the small signal resistance of the transistor to match the effective resistance of the switched-capacitor network. The filter is tuned by varying the rate of which the switched capacitor network is clocked thereby changing to effective network resistance. The control voltage (Vc) responds by forcing the transistor resistance to match the new effective resistance of the switched-capacitor network. The control voltage is used to tune the filter and changes to compensate for variations in the filter capacitor and transistor, which track variations in the filter transistor and capacitor.
