Title: Speed controller for harvesting machine - has circuit for providing rate control and limits on command signal to hydraulic pump motor
Inventor: MYERS A H
IPC: F16H61/42
Filed: 1985-06-04
Abstract: The controller is fitted to a harvester having a motor (20) driving a variable flow hydraulic pump (16) which supplies pressurised fluid to hydraulic drive motors (12). The drive speed is controlled by control of the pump motor. The controller (26) includes a speed setting potentiometer (32), an impulse counter (38,40) serving as a speed detector on the principal hydraulic drive motor, a frequency-to-voltage converter producing an analogue voltage signal proportional to the principal motor speed a comparator which compares the measured speed signal against the reference signal, and an electronic circuit with rate control and limit circuits which combines fast responding and slow responding signals to form a command signal for the pump motor. - The command signal forces the hydraulic motor to slow quickly when the principal motor slows, and to accelerate rapidly until the limits are reached as the load is decreased on the harvester.

Abstract: ELEVATOR SYSTEM                 ABSTRACT OF THE DISCLOSURE         An elevator system including an elevator car mounted in a structure to serve the landings therein, and an opto-electronic position detector for determining when the elevator car is within a predetermined distance from a selected landing.  The position detector includes a source of electromagnetic radiation which is pulsed at a predeter-mined rate, such as a light emitting diode, and a photo-voltaic device which provides an output current having a magnitude responsive to the level of the electromagnetic radiation it is subjected to, such as a photo transistor. The source of electromagnetic radiation and photovoltaic device are mounted in a common housing with a beam splitter, such as a half-silvered mirror, and this assembly is pref-erably mounted on the elevator car.  A control device or target is mounted adjacent each landing to be served by the elevator car, with the control device including a retro-directive reflective surface or retroreflector.  The housing is oriented such that the angle of incidence of a beam of electromagnetic radiation provided by the source of electro-magnetic radiation strikes the retrodirective surface with an angle other than 90 degrees.  The photovoltaic device is electrically biased to provide an output current regardless of the level of the electromagnetic radiation applied to the photovoltaic device.  When the photovoltaic device receives electrical radiation, such as from the retrodirec-tive surface, its output current changes, and means respon-sive to changes in the output current energizes a translating device when the output current changes at a rate indicating the photovoltaic device is receiving the pulsed electro-magnetic radiation from the source thereof.
