Abstract: A telescopic gun sight is clamped to a mount which is mounted on a base for limited relative sliding movement fore and aft of the barrel of a rifle, to which the base is secured. Resilient bushes of elastomeric material are disposed within bores in the mount, and fixing bolts pass through the bushes to clamp the mount to the base. The resilience of the bushes allows the mount to move slightly relative to the base, and returns the mount to its original datum position after such movement. In this way, shocks that may otherwise damage the sight and/or shift its position relative to the barrel of the rifle may be absorbed--particularly recoil shocks upon firing. In other embodiments, relative movement of a mount relative to a base is possible in more than one direction, thereby to absorb shocks in other directions, as may be caused by, for example, accidental knocks.

Abstract: A firing mechanism for an air weapon in which air is compressed in a cylinder and expelled through a discharge port in the cylinder to propel a projectile along a barrel by a piston executing a firing stroke. The mechanism comprises a piston slidably located within a cylinder with the crown of the piston facing towards the discharge port. A spring urges the piston towards the discharge port. A bobbin is located behind the piston crown, which is axially movable with the piston during at least a portion of the firing stroke and is axially movable relative to the piston at the end of the firing stroke.

Abstract: A frame (10) for releasably framing articles such as pictures, photographs, posters and menus includes a plurality of elongate members (12, 14, 16 18) having mitred ends mated together, and an elastic band (20), the elastic band being located in a continuous channel formed, on assembly of the frame, by the alignment of sub-channels (27) located along the length of each member, and the elastic band being in tension around the frame so as to pull the members together, each sub-channel having an entrance passage leading into it along the whole of its length, the entrance passage allowing the elastic band to be threaded into the channel and preventing the elastic band from being visible after assembly of the frame.

Abstract: The present invention is directed to a frame (10) for releasably framing articles, such as pictures, photographs, posters and menus. The frame comprises a plurality of elongate members (12, 14, 16, 18) having mitred ends mated together, and a tensible loop (20) wherein the loop is located in a continuous recess (28) formed, on assembly of the frame, by the alignment of sub-recesses (27) located along the length of each member, and wherein the loop is in tension around the frame so as to pull the members together.
