Abstract: An electric strike for a door frame, comprising: a body; a keeper moveably attached to the body for selectively retaining a latch bolt on a door; a blocking element movable between a blocking position in which the blocking element locks the keeper to prevent a latch from being moved past the keeper, and an unblocking position in which the blocking element unlocks the keeper to allow the latch to move past the keeper; an electronically controlled electric actuator for moving the blocking element between the blocking position and the unblocking position; and an override mechanism to override the electric actuator.

Abstract: A bagpipe reed system is disclosed. A reed seat body is substantially tubular and includes a bleed hole through one side. An open end is attachable to a bagpipe drone or chanter. A planar reed substantially overlies the bleed hole and is held at one end by a reed mount to the reed seat body. The reed seat body has an external reed seat surface around the bleed hole which is shaped such that the planar reed diverges from the reed seat body. The reed seat surface is preferably a curved plane. A reed pitch adjuster is preferably mounted to the reed seat surface.
