The invention relates to a control valve for the control, independently of a load, of a hydraulic consumer with a distributing slide valve to control the direction of movement and the speed of movement of the consumer and a throttle valve associated with the distributing slide valve. The throttle valve, when there is a connection of a pump with the consumer, can be pressurized toward an open position by the pressure downstream of the throttle point of the distributing slide valve, and toward a c...

A control system current (DC) motor in which driving signals are supplied to the stator windings of the motor in accordance with a measurement of the rotational speed of the motor and the position of the rotor of the motor. The speed measurement is obtained by combining a first signal representing the rotational speed of the motor derived from a measurement of the back-EMF developed in the stator windings of the motor and a second signal representing the rotational speed of the motor derived fro...

A fuel injection control strategy and system for engines for maintaining good performance under normal running conditions and also for providing cylinder engine speed slow-down under abnormal conditions by cylinder skipping. Transitional operation between these modes is improved by changing injection timing and/or injection duration of the operating cylinders during this time. Adjustment in spark timing may also be incorporated along with this routine.

A control pod for a plug and cord assembly secures the electrical appliance to which the cord is attached and prevents insertion of the plug into a power outlet by having an upper section connected to a lower section by a hinge on one side and a lock oppositely disposed from the hinge.

A control circuit for controlling a semiconductor component (2) comprising an emitter (E), a collector (C) and a gate (G), the control circuit comprising a gate driver (GD) the output of which is connected to the gate (G) of the semiconductor component to be controlled. The control circuit further comprises a resistance coupling (1) where two series connections of a diode (V1, V2) and a resistor (R1, R2) are in an antiparallel connection and connected between the emitter (E) of the semiconductor...

A method of controlling the operation of a fuel injector of a fuel system using a control system of the type comprising an accelerometer associated with an engine and arranged to sense vibrations thereof, and monitor means arranged to monitor the output signal of the accelerometer to detect vibrations of the engine, is described. The method comprises applying a drive pulse to the injector, using the monitor means and the accelerometer to determine whether or not the application of the drive puls...

A control device for a machine has a control lever operative to rotate about two axes. The control lever is rotatably mounted on a shaft within a frame and is in communication with a first rotation sensor to detect movement of the control lever about the first axis. A first pair of adjustable abutment members are operative to center the control lever within the frame. The control lever and frame are operative to rotate about the second axis. A second rotation sensor is operative to detect moveme...

A process of culturing a microorganism in a culture medium in which process the addition of feed medium is controlled by using the production of a by-product as a measure of the culture conditions, characterized in that the by-product is an electrically charged metabolite produced by the microorganism, and in that the production of the metabolite is monitored by measuring the conductance of the culture medium. The metabolite may be acetate and the microorganism may be yeast which is genetically ...
