Abstract: A bolt restraint mechanism for restraining a bolt of a bolting mechanism. The bolt restraint mechanism includes a bolt moveable between thrown and retracted positions and a catch plate having an aperture through which the bolt extends. The catch plate is biased to pivot such that a restraint surface of the aperture pushes against the bolt to restrain movement of the bolt. A release trigger is arranged such that when depressed the release trigger pushes against the catch plate to pivot thereby releasing the restraint surface from pushing against the bolt to release the bolt. The catch plate may be biased such that when the restraint surface pushes against the bolt to restrain movement of the bolt, the catch plate is non-orthogonal to the bolt.

Abstract: A bolt module is disclosed. The bolt module comprises: a bolt moveable between a thrown position and a retracted position; an anti-thrust member moveable between a release position in which the bolt can be retracted and a plurality of blocking positions obstructing driving back of the bolt under action of an external force on the bolt and, a first rotor assembly capable of accepting a drive element, the first rotor assembly arranged to drive the bolt and to move the anti-thrust member between the plurality of blocking positions and the release position. Each of the plurality of blocking positions may respectively limit to different extents the driving back of the bolt under action of an external force on the bolt. There is also disclosed a leaf or door comprising the bolt module, wherein the bolt module is mounted on the leaf or door for securing the leaf or door.

Abstract: Headgear for use with a respiratory mask is described. The headgear comprises a continuous and substantially curved elongate member extending in use below a user's nose and at least two headgear straps capable of attachment to the ends of the elongate member. A mask attachment on the elongate member is disposed to sit below or on one of said user's nose, mouth, upper lip and an inlet to the mask. The attachment is capable of receiving the mask.

Abstract: A clutch and handle for applying rotation to a lockable mechanism is disclosed. In particular, the handle is adapted to prevent damage to the handle or a lockable mechanism when excess pressure or torque is applied to the handle. The torque limiting clutch mechanism limits the torque which can be applied by the handle such as to a lockable mechanism for securing a leaf within a frame. The torque limiting clutch mechanism comprises first and second rotors in confrontation to transmit rotational drive from the handle to the lockable mechanism. The first and second rotors are arranged to slip against each other beyond a maximum transferred torque.
