Abstract: 975,072. Control of two motors. TECHNICON INSTRUMENTS CORPORATION. April 4, 1962 [April 20, 1961], No. 12933/62. Heading H2J. [Also in Divisions B1 and B2] A vessel 12, Fig. 1, containing immiscible liquids to be separated from each other by centrifugation (see Division B2) is mounted in a frame 22 for rotation about a vertical axis by a D.C. shunt motor 14 through a belt and pulley drive 66, 68, the vessel, frame and motor assembly being rotated about a horizontal axis, prior to centrifugation, by an A.C. capacitormotor 16 through chain and sprocket wheels 134, 136, 138 in order to intermix the liquids in the vessel 12. The motor 14 is fed through slip rings 154 with current supplied from a rectifier 190, Fig. 8, and the motor 16 is braked by direct current supplied from a rectifier 198. The operation of the motors are controlled by timers 170, 172 which are so interlocked that the motor 16 operates first and is stopped after a predetermined intermediary period with the vessel 12 is in its vertical position whereupon the motor 14 is operated until the end of the centrifugation period. The timers incorporate clutch coils 224, 270 and motors 238, 274. The control circuit is shown in Fig. 8 in its deenergized condition. Closing of the start button 222 causes energization of the timer 170, relays 206, 208 and motor 16. Closing of contact g of relay 208 due to its energization opens contact i and thereby disconnects the resistance 218 of a thermal-relay 216 from line L2 so that contact n closes. At the conclusion of the intermixing timing period the circuit is arranged so that the motor 16 is shut off and braked only when an actuating arm 140 secured to the hub of the sprocket wheel 138, Fig. 1, engages the actuating arm 142 of a microswitch 144 in which position the vessel 12 will stop in its vertical position. If the intermixing timing period ends at a time when arm 142 is not engaged by arm 140, contact l of the microswitch, Fig. 8, is closed relays 206, 208 remain energized and motor 16 continues to rotate and rotates arm 140 to engage arm 142 causing opening of contact l and closing of contact k thereby de-energizing relay 206 after which the arms move out of contact with each other so that relay 208 is de-energized and the braking circuit to motor 16 is completed. A circuit is also completed through resistance 218 of the thermal-delay relay 216 and, upon heating of this resistance, contact 220 opens contact n which opens the circuit to the rectifier 198 and ends the braking action, the vessel 12 being in its vertical position ready for centrifugation. Opening of contact e initiates the operation of the timer 172 and at the same time completes the circuit to the rectifier 190 and energizes the motor 14. At the conclusion of the centrifuging timing period the timer 172 causes the opening of the circuit to the rectifier 190 and stops the motor 14.
