Abstract: A brake control valve arrangement includes an electro-pneumatic brake control valve block having a hold valve and a vent valve, a main regulator valve and an emergency and a tare pressure regulator. The valve block has an inlet for a brake supply pressure and an outlet for a brake cylinder, wherein an inlet and a vent pneumatic opening is provided for the hold valve and vent valve. The arrangement also includes a configuration module in pneumatic connection with the brake supply pressure and providing a pneumatic path to the inlet, and a pneumatic path to the vent valve from the brake cylinder, the arrangement also including at least one choke configured to control air flow in pneumatic paths to the inlet opening and vent opening.

Abstract: A pressure equalization valve arrangement for a rail brake system includes a hold valve and a membrane vent valve each having a control chamber. The hold valve and vent valve are piloted by a respective solenoid valve. A further solenoid valve is connected to the control chamber of the vent valve to allow the pressure across the vent valve membrane to be equalized with the brake cylinder pressure to decrease the pressure difference across the membrane. This results in an improved vent time.

Abstract: An arm support system incorporates a harness with a support plate engaged to the harness. The support plate has an engagement element. A wrist strap has a mating engagement element and the wrist strap is adapted to be engaged to a wrist of an injured arm. Engagement of the mating engagement element onto the engagement element supports the injured arm.

Abstract: A brake control valve arrangement for controlling application of a braking force includes an electro-pneumatic brake control valve block including a hold valve and a vent valve (PRESSURE CONTROLLER), a main regulator valve (RELAY VALVE) and an emergency and a variable load control pressure regulator. The valve block has an inlet for a brake supply pressure, and an outlet in pneumatic connection with a brake cylinder. A pilot pressure into the main regulator valve from the variable load control pressure regulator is controlled by a remote release solenoid valve (CONTROL CHAMBER VENT MAGNET VALVE). The remote release solenoid valve adapted to vent brake cylinder pressure to atmosphere when de-energized thereby enabling release of the wheel braking force via the main regulator valve.

Abstract: An electropneumatic rail brake system configured to provide emergency braking including an emergency magnet valve which controls air flow into an emergency regulator valve, which valve has an emergency back-up chamber. The emergency regulator provides an output pressure nominally equal to the variable load pressure and no lower than the tare back-up. The magnet valve is closed when energized and when de-energized, pressure is allowed into the emergency back-up chamber, Regulation of the brake cylinder pressure continues during an emergency application such that the brake cylinder pressure applied during an emergency stop does not drop below a predetermined level. In the event of power-loss during an emergency brake stop, the nominal emergency brake pressure is applied to the brake cylinders.

Abstract: A brake system for a railway vehicle having wheel slide protection includes a main brake pipe fluidly connected to a distributor, and an auxiliary reservoir fluidly connected to the brake distributor, the distributor being fluidly connected to one or more brake cylinders. A further reservoir is provided, compressed air flow to and from the further reservoir being controllable by a valve, operation of the valve being controlled by a control unit adapted to detect wheel slide. The control unit is adapted to switch air supply between air from the auxiliary reservoir and air from the further reservoir in the event that wheel slide is detected.

Abstract: A platform screen door system includes a fixed driving panel and at least one door leaf slidable relative to the fixed driving panel. Further included is a telescopic guide including a fixed guide mounted on the fixed driving panel, a moving guide mounted on the at least one door leaf, and a moving intermediate guide mounted on the fixed guide. Also included is a drive means for slidably moving the at least one door leaf from a closed position to an opened position wherein the at least one door leaf overlaps the fixed driving panel.
