Abstract: An acoustic mount is described for damping vibrations between a primary structure of a building and a secondary structure of a building and which has a vibration damper interposed in use between the primary and secondary structures. The vibration damper is resiliently compressible in the axial direction and has at least one resiliently compressible damper element which is elongated in the axial direction so that the axial length of the damper element is greater than half of a transverse width thereof. The damper element reduces in cross sectional area in the axial direction; has a convex outer surface in planes containing the axial direction; and possesses non-linear axial deflection or compression characteristics under a range of static loading conditions enabling effective vibration damping or vibration isolation for a substantial range of loadings of the acoustic mount in use.

Abstract: Apparatus (50) for fitting to an end of an internal wall, said apparatus (50) including a web portion (52) and a pair of legs (61, 63) extending from the web portion (52) in the same direction; at least one of the legs (61) in said pair of legs (61, 63) having a recess (56) that extends into a space formed by the web portion (52) and each of said legs (61, 63) such that a shadow line is created by the recess (56) near to the wall end in the overall finish of said wall.

Abstract: A clip or connector is provided for assembling part of a door or window frame having first and second sheet material frame members to be retained in abutting relationship and in a particular predetermined position relative to each other. Each frame member has a concave channel formation along its length. The clip has a head and a body with a neck therebetween. The head engages with a tight interference or frictional fit within the channel formation of the first frame member and the body engages with a tight interference or frictional fit within the channel of the second frame member, such that the frame members are located and held in their particular predetermined position.

Abstract: There is disclosed an acoustic mount for dampening vibrations between two structures mounted or coupled in use to each other. The mount includes a vibration dampening member having a first portion, a neck and a second portion. The second portion has a head. The dampening member has a bore running through the first portion, neck and head to receive a component, such as a fixing member such as a screw, for engaging or coupling to a first one of the two structures. A support member is also described to which a second one of the two structures is secured or coupled in use. The support member has an aperture to receive the dampening member. The dampening member is an integral unit and the head can be passed through the aperture and positioned such that said head resists withdrawal through the aperture. The support member is interposed between the first portion and the second portion.

Abstract: The method is for facilitating the watching of films, TV programs and the like, meant for deaf people and people with hearing impairment. The method allows a transparent or translucent shadow-graph to be produced on the screen.
