Abstract: A device (1) for testing pneumatically operated brakes of a first vehicle (22) and of a second vehicle (23) being connected and having interconnected brake systems. A device supply line (3b) and a device control line (4b) are arranged for connection to respective corresponding supply and control lines (3a, 3c, 4a, 4c) in the vehicles such that the device (1) is fluidly connected into and between the brake system of the first vehicle (22) and the brake system of the second vehicle (23). A method of activating the brakes (5) of a trailer unit (23) which is connected to a tractor unit (22), without activating the brakes of the tractor unit (22), provides braking action by employing the device (1), and includes remotely activating the first valve means (9) in order to provide braking action.

Abstract: A device (1) for testing pneumatically operated brakes of a first vehicle (22) and of a second vehicle (23) being connected and having interconnected brake systems. A device supply line (3b) and a device control line (4b) are arranged for convection to respective corresponding supply and control lines (3a, 3c, 4a, 4c) in the vehicles such that the device (1) is fluidly connected into and between the brake system of the first vehicle (22) and the brake system of the second vehicle (23). A first valve means (9) is operable for temporarily and releasably connecting the device supply line (3b) to the device control line (4b), whereby braking action may be effected on the second vehicle (23) via a second vehicle control line (4c), independently of the braking action on the first vehicle (22).

Abstract: A fluid treatment tank for use in a well fluid processing system. The tank is divided into at least three compartments, including an oil treatment compartment for receiving oil from a separator vessel of the well fluid processing system so as to allow stabilization and/or final separation and treatment of the oil, a reject treatment compartment for receiving reject fluid from one or more water treatment units of the well fluid processing system so as to allow gravitational separation of heavier and lighter components of the reject fluid, and a water treatment compartment for receiving de-oiled water from one or more water treatment units of the well fluid processing system so as to allow degassing and/or final separation of the water. Also, a well fluid processing system including such a fluid treatment tank.
