Abstract: A module for a braking system includes a movable housing configured to transfer a braking force from an input shaft to an output shaft, a first movable member slidably received within the housing and connected to the output shaft, a second movable member slidably received within the housing, a first resilient member biased between the first movable member and the second movable member, such that a force applied to the second movable member is applied to the first movable member via the first resilient member, and a second resilient member biased between the second movable member and the housing, such that a force applied to the housing is applied to the second movable member via the second resilient member. The first resilient member yields or compresses upon application of a first braking force to the input shaft, and the second resilient member yields or compresses after the first resilient member.

Abstract: A device for assisting the opening and closing of a door in a structure. The device may comprise: a door shaft configured to rotate about a longitudinal axis thereof in both a first direction and in a second opposite direction, and configured to be mounted to the structure to form a hinge about which the door may rotate in the both the first and second directions relative to the structure; a first actuator linked to the door shaft and configured to control a speed of rotation of the door shaft in the first direction; and a second actuator linked to the door shaft and configured to drive rotation of the door shaft in the second direction. The second actuator is an electromechanical actuator.

Abstract: New methods and devices are described that are aimed at preventing the outbreak of fire in a hydraulic rotor brake. These methods and devices can be used in the rotor brake of a helicopter and comprise a first and second seal, with a drain groove positioned in between these two seals to drain leaked fluid away from the hot parts of the brake. In the brakes described, the second seal is positioned closer to the heat sink of the brake than the first seal. The drain groove is also connected via a channel or channels to a drain outlet or outlets.

Abstract: A system for monitoring engagement and wear in a brake include: a pin, a first marker positioned on the pin at a first location; a second marker spaced from the first marker long the pin; and a first fixed sensing arrangement. The pin extends in an axial direction parallel to the axis of rotation, and is in contact with and moves with the moveable brake pad in use. The first fixed sensing arrangement is adapted to provide a first signal when adjacent the first or second marker, and a second signal otherwise. The first and second markers and the first fixed sensing arrangement are positioned such that the second signal indicates that the brake is in the engaged position, and a change from the second signal to the first signal indicates that the moveable brake pad and the second brake pad have been worn down by a predetermined amount.

Abstract: A brake component indicator configured to provide a visual indication of the release state of the brake component; the indicator comprising an indicator element connected to the brake component and moveable with the component during a braking operation, whereby the indicator element is provided with means to provide a visual indication of the direction and/or the distance moved by the indicator element during the braking operation. Preferably, the indicator element is in the form of a rod connected to a brake disk or pad that engages a moving part in a braking operation to brake the moving part, the rod provided with indicator means whose position is an indication of the distance the brake disk or pad has traveled to engage the moving part.
