Abstract: A control valve assembly for a total pressure hydraulic brake is provided with an input port, and output port, a remote control input port connected to a hydraulic fluid supply, a first response which is moved together with depression of a brake pedal, a second response which is moved by the hydraulic fluid flowing through the remote control input port, and a control valve which operates in accordance with the movement of either the first or the second response. The control valve supplies the hydraulic fluid from the input port to the output port in response to the hydraulic fluid flowing through the remote control input port, as well as the depressing force exerted on the brake pedal.

Abstract: A disconnecting switch arrangement for a high voltage disconnecting switch equipped with an earthing device for use particularly in a metal clad insulated substation. The arrangement comprising a disconnecting unit, an earthing unit and an actuating unit for actuating the disconnecting unit and the earthing unit. The disconnecting unit comprises a stationary contact member, a common stationary contact member at a standard spacing from the stationary contact member and a common movable contact member for disconnecting from and connecting with the stationary contact member and the common stationary contact member and is moved in a circular motion by the actuating unit. The earthing unit is comprised by an earthing contact member, the common stationary contact member and the common movable contact member each of which is commonly used with the disconnecting unit.
