Title: Rotary centrifugal machine
IPC: B04B9/12
Filed: 1975-12-08
Abstract: 1503768 Centrifugal dryer ELLIS CORP 8 Dec 1975 [12 Dec 1974] 50202/75 Heading B1D [Also in Division F4] A rotary centrifugal machine, e.g. for drying laundry, comprises a casing 22, which includes a perforated gasket (28), mounted for rotation about an axis, a drive coupled thereto for rotating it, a conveyor 82 for loading the casing, an unloading assembly 24, means for sensing a predetermined imbalance in the load in the casing, and control means operated by the sensing means for operating the assembly 24 during rotation of the casing so that the unloaded material is centrifugally ejected, and conveyors 122..130 and 146, 148 for reloading the ejected material. The machine operates as follows:-Fig. 11 showing the control circuit with the machine at rest. Closing of switches 186, 188 energises coil 200 to close contacts 200c to pressurise an actuator (54), see Fig. 4 (not shown) and release a brake (52), and to close a switch 56 to actuate drive motor 46 which is intermittently energised under the control of a low r.p.m. switch 190. At these speeds, a high r.p.m. switch 192 remains closed, so that actuator 96, see also Fig. 3, is pressurised by fluid at 120, to lift a moveable wall (88), Fig. 4, to eject laundry onto the conveyors 122..130 for discharge at 140. At its top position, the wall 88 actuates a switch 160 to energise 202 and to cut off pressure and allow the wall 88 to descend and actuate a switch 162A and drive the motor for the loading conveyor 82. Energising 202 closes 202c and energises 204 which starts final unloading conveyor 130, and after a time delay 206, 206A, the earlier unloading conveyors 122..128. A second time delay 208 is then actuated to ensure complete discharge from the conveyors, after which all are deenergised by 208A. High speed extraction. Energisation of 204 closes 204D to energise time delay relay 210 which, after a predetermined loading time, energises 196 to close 198A and open 198B, so de-energising all circuits for the conveyors and actuator 96. Contacts 190 are bye-passed, and the motor 46 is driven continuously under time control 194, until 198A, 198B are returned to the state shown in Fig. 11, and the loading- unloading sequence is re-established on closing of 192 as the casing 22 slows down. Sensing imblance of load. Load imbalance causes lateral movement of the casing and actuates a switch 142, the circuit acting temporarily to discontinue motor 194, slow the casing 22, and actuate the unloading assembly 24. The unloaded laundry is collected in distributed condition and reloaded into the casing 22 by the conveyors 146, 148, 82, after which the high speed extraction cycle recommences. Conveyor 130 moves in the direction to deliver to conveyor 146, not to discharge at 140.

Abstract: 1,273,647. Control of D.C. motors. VYZKUMNY USTAV ZDRAVOTNICKE TECHNIKY. 26 Oct., 1970 [12 Nov., 1969], No. 50763/70. Heading H2J. [Also in Division G3] A thyristor TY1 and a transistor T1 are connected in series between A.C. source and a D.C. motor M, the thyristor passing current during a portion of a half-cycle of the A.C. supply which depends on the back EMF of the motor, thereby to stabilise the speed at a predetermined value, and the transistor being arranged to cut off the supply to the motor at a predetermined motor current, thereby to provide overload protection for the motor. A reference voltage for controlling the thyristor TY1 is provided by a zener diode ZD1, associated with capacitor C1 and resistors R1, R2. The back EMF of the motor opposes the voltage across the capacitor C1 to determine the firing-angle of the thyristor. When the armature current exceeds a predetermined value, the voltage-drop across resistor R6 is sufficient to render zener diodes ZD2-ZD4 conductive so that the transistor T1 becomes non-conductive. The motor may drive a dental drill.
