A column packing system comprises a control unit provided with software for calculating the breakpoint where a movable adapter comes into contact with a settled bed of bed media. The calculated breakpoint is used by the control unit to determine how much further the movable adapter has to move into the column in order to achieve a desired amount of bed compression.

摘要:
To measure a sum of electrical currents in different conductors, light is led in an optical sensing fiber around all the conductors. The sensing fiber can be wound around the conductors in a single loop or in several individual loops. Interspersed polarization maintaining fibers and retarders can be used to transfer the light between individual loops for preventing undesired signals from stray magnetic fields. The method has high accuracy is particularly suited for measuring large currents that sum up to zero.

A lubrication system for a four stroke engine including an oil pan for storing lubrication oil; a crankcase, wherein a crankshaft is disposed, which crankshaft has a balance weight and is coupled with a piston of a cylinder; a gear assembly room; a rocker-arm chamber; and a gas-oil separator for separating gas and oil from a mix of gas and oil; wherein the oil pan communicates with the crankcase by an oil suction passage, in which a first check valve is disposed; the crankcase communicates with the gear assembly room by a first oil delivery passage; the gear assembly room communicates with the rocker-arm chamber by a second oil delivery passage, and the gear assembly room communicates with the oil pan by a third oil delivery passage; the rocker-arm chamber communicates with the crankcase by a first oil return passage having a second check valve therein.
摘要:
A method for controlling an ignition system of an internal combustion engine having a primary firing pulse generator for charging a capacitor. An electronic switch is included for discharging the capacitor via an ignition coil to generate an ignition voltage. A microcomputer operates the switch to control the ignition timing of the generator. The microcomputer is in communication with a speed sensor that detects the rotational speed of the engine and a speed limitation control that limits the engine speed to a limitation speed below the clutch-in speed of an included centrifugal clutch. The speed limitation control is active or activated when one of either starting the engine or an operating problem of the power tool is detected. The speed limitation control is deactivated when a low speed state of the engine is detected.
