Title: Cell-washing centrifuge and method
IPC: G01N33/483
Filed: 1970-05-04
Abstract: 1,241,539. Centrifugal separators; mixing apparatus. AMERICAN HOSPITAL SUPPLY CORP. 4 May, 1970 [27 Oct., 1969]. No. 21283/70. Headings B1C and B2P. Blood cells in the bottom of an open-topped centrifuge tube are mixed with washing liquid by directing a stream of the liquid against the upper portion of the inner surface of the tube while the tube is inclined to, and is travelling about, an axis of centrifugation and simultaneously restraining movement of the tube about its own axis whereby the liquid accelerates under the influence of centrifugal force along the inner surface of the tube from the upper to the lower portion thereof and into forceful contact with the cells to dislodge them and mix thoroughly with them. A cell-washing centrifuge, Fig. 3, comprises a casing 11, a hood 12 and a tube-supporting head 13. The top of the casing is provided with a well 18 in which is disposed the tubesupporting head 13 which is slidably received on a motor-driven shaft 19 to which is fixed a friction drive member 21 in engagement with the underside of the head. The head is provided with tube-receiving recesses 25 each having a vertical outer surface 25a and an inwardly sloping inner surface 25b to permit pivotal movement of each tube 26 between an inclined washing position, Fig. 3, and an upstanding decanting position, Fig. 9. The head is splined to a shaft 30. The hood 12 consists of an arm 31 pivotally carried by a shaft 32 connected to a hood lifting and pivoting mechanism 33 actuation of which is synchronised with the operation of the head driving motor 24 through timing and synchronizing means 36 which also controls the operation of a flow-control valve 16. Fixed to the shaft 30, which is rotatably supported in bearings 37, 38 in the arm 31 is a distributor 39 which is secured to a cover 40. The distributor is formed with an annular chamber 46 to which washing liquid is supplied from a source 13 via a tube 15 and the control valve 16. The chamber 46 has an upwardly and outwardly sloping side wall up which the washing liquid 61, Fig. 7, moves under the action of centrifugal force and passes into passages 50 of circumferentially spaced nozzles 48 projecting downwardly through openings in the cover 40 into the open ends of the tubes. The cover 40 has an internal annular shoulder 54 which engages the upper ends of the tubes 26 when in an inclined position and an outwardly and downwardly inclined undersurface which is slidably engageably with the upper ends of the tubes 26 to permit gradual outward pivoting movement of the tubes under the action of centrifugal force. The cover as part of the hood is slowly raised during rotation of the head 13.

An automatic voltage-control system comprises a transformer 1 having a resistor 3 connected in its primary circuit and supplying, via secondary winding 10 and rectifier 9, a load connected across terminals 13, 14, and via secondary winding 6, and rectifier 8, a separate artificial load constituted by a valve 7 which is controllable in accordance with the voltage across terminals 13, 14. Part of the power supplied to the normal load circuit is provided by a separate transformer 19, of the saturable type, effecting partial control of the voltage, and rectifier 15. The heater 26 of a diode 25 is connected across terminals 13, 14, and variation of current through diode 25 due to voltage variation at 13, 14 is amplified by valve 32 and applied to the control grid of valve 7 thus changing the load on transformer 1 and altering the voltage drop across resistor 3 to compensate for the voltage change at 13, 14. The valves 25 and 32 may be replaced by transductors. Specification 739,301 is referred to.

Abstract: 1,029,004. Washing vehicles. E. CRUGNOLA, and A. SONZINI. May 28, 1964 [May 29, 1963], No. 22083/64. Heading B7J. [Also in Division H2] A vehicle washing and drying apparatus has an arch 10 which is reciprocated along rails 8 under automatic control, the length of travel being controlled according to vehicle length. The arch has carriages 11 including driven wheels, spray nozzles 15, a fan 12 delivering air through aperture 13 and six heat radiating lamps L which are covered by doors under the control of piston and cylinder mechanisms, Fig. 2 (not shown), when the vehicle is being washed. A manual control switch controls the supply of water from a pump to nozzles 15 during a pre-wash cycle; the supply of detergent, air and water to the nozzles via a mixer during a washing cycle; the supply of water for rinsing; and the uncovering and actuation of lamps L and fan 12 for the drying cycle; in various positions of the control switch' cooks can be operated to tap off water and the cleaning fluid through a spray or brush respectively. The pistons of the lamp doors are operated by compressed air acting on oil in a reservoir. The electric control circuit, Fig. 4 (not shown), includes electric motors for carriages 11 and for the pumps which pressurize the air and water, push buttons which enable certain valves to be operated whereby water and cleaning fluid are supplied to the spray and brush respectively, various warning lamps and a time delay apparatus which can be adjusted to reverse the motors in carriages 11 when the portal has travelled the length of a vehicle. A limit switch F1 brings the portal to rest at its initial position where the manual control switch is operated to produce the next cycle in the washing and drying sequence. A switch in the control circuit also enables the doors of the heating lamps to be opened to enable the parabolic reflectors to be cleaned. During the drying cycle, the portal returns at a faster speed than for its forward movement.

Filed: 1949-08-26
Abstract: 670,545. Control of D.G. motors. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Aug. 26, 1949. [Sept. 4, 1948] No. 22223/49. Class 38 (iii). [Also in Group XXXV] An electronic system for energizing a directcurrent motor from an alternating-current source comprises a transformer, controllable rectifier tubes connected between said motor and said transformer so as to provide full-wave rectified current, for said motor, an inductive reactor series-connected with said motor and a valve circuit having a low impedance compared with said transformer connected across said series-connected motor and reactor, said valve circuit being poled to be blocked. for said rectified current. The armature 11 of a direct-current motor is connected through rectifying valves 6, 7, to a, power transformer 2, an inductive reactor 13 being connected in series with the motor. A. shunt circuit having a low impedance compared with the transformer is connected across the armature and reactor, this circuit containing a valve 16 which permits the inductive current to flow through the motor only in the direction of the rectified current. The reactor 13 has a filtering effect, sustaining the armature current when the anode voltage of the rectifiers 6, 7, decreases towards the end of each cvcle. This sustaining action of the filter is increased by the connection of the valve 16 since the discharge current of the. reactor acts through the low impedance path of the valve rather than through the transformer winding in opposition to the transformer secondary voltage. A resistor 17 is connected across the armature to ensure a certain minimum load current in the reactor 13, especially at no-load operation of the motor. Conduction of armature current is thus maintained over the whole load and speedrange, unstable conditions of transfer from discontinuous to continuous operation of the main rectifiers being avoided. The control circuits of valves 6, 7, each comprise a portion of the secondary winding of a transformer 24 across which is developed an alternating grid voltage component which is dephased by substantially 90 degrees in relation to the anode supply. A constant direct-voltage control component for the valves 6, 7, is impressed upon resistors 34, 35, a variable direct component being derived from resistor 33 in the anode circuit of control valve 41, the conductivity of which is reduced to advance the firing-angle of the main rectifiers. The valve 41 is controlled in accordance with the difference between a reference voltage obtained from rheostat 36 and an armature voltage-measuring component derived from resistor 37 so that the motor speed may be held at a set value. The resistance-drop in the armature circuit is compensated by means of resistor 44 which is connected in the grid circuit of valve 41 and in the anode circuit of valve 47. A resistor 9 is connected in the motor armature circuit and in the grid circuit. of valve 47 to provide the corrective component proportional to the armature resistance drop.
