Title: Improvements in and relating to Electric Motor Control Systems.
IPC: H02P1/16
Filed: 1916-08-08
Abstract: 105,013. Igranic Electric Co., (Cutler- Hammer Manufacturing Co.). Aug. 8, 1916. Systems for alternating-current motors only.-In a control system for motors with separate high and low speed windings, the reversing-switches are common to both windings, and the actuation of the low-speed switch follows immediately upon the closure of one of the reversing- switches. The actuation of the highspeed switch follows the operation of a relay controlled by a hand-switch. The operating-coils of the reversing-switches 1, 2 are connected to contacts 9<b>, 9<c> of the hand-switch 9, and the operating-coils of the low and high speed switches 3, 4 are connected through the contacts of the relay 10 in its down or up position respectively. The switch 3 controls the primary winding P associated with a squirrel-cage secondary S for slow speed and high torque, while the switch 4 controls the primary winding P<1> associated with a slipring secondary S<1> for high speed. When the arm 9 is moved to the left on to the contact 9<b>, the reversing-switch 1 is closed, and the brake 13 is lifted. The switch 3 is also closed, its actuating- circuit being completed through the relay 10 and the auxiliary contacts on switch 1. The winding P is energized and the motor runs at slow speed. If the arm 9 is moved on to the contact 9<d>, the relay 10 is operated to break the circuit for the switch 3 and to close the circuit for the switch 4. The latter switch closes to connect the high-speed winding P<1>, and the rotor resistances R, R', R<2> are cut out by contactors under the control of the relay 8. If the switch arm 9 is moved to the right from its zero position, the switches 2, 3, 4 will be separated, and the motor will rotate in the reverse direction. If the switch 9 is returned to ' off ' while the motor is running at high speed, the relay 10 drops and the switch 4 opens, but the circuits of the reversing-switch and the switch 3 are maintained through the switch 11 closed by a centrifugal device. With the low-speed connexions made, the motor brakes itself, and when the speed drops sufficiently, the switch 11 opens and interrupts the maintaining- circuits of the closed switches.

Abstract: 966,930. Mixing fibres. K, OTA. March 26, 1962, No. 11465/62. Headings D1F and D1N. A method of producing a homogeneous mixture of different kinds of textile fibre comprises making a pile of the different kinds of fibres in a first chamber scraping the layers thus formed vertically from one side and repeating the piling and scraping process in a second chamber. Each kind of fibre is fed in turn, through a blower 1, tangentially into a dust eliminating apparatus 2 through which the fibres spiral down. Dust partly by suction and partly by centrifugal force passes through a filter net 7. Propellers 14 circulate the fibres in the chamber 9 and they slowly and evenly fall on to a feed conveyer 10. The spikes of the conveyer 11 scrape the layers of fibres and the fibres then pass via roller 17 and tube 18 to another similar apparatus where the process is repeated. Various finishing agents are supplied from the nozzles 20.
