Abstract: A threshold seal apparatus for a doorway, the threshold seal apparatus comprising a floor-mountable channel portion, a seal configured to be received within the channel portion, and an actuation mechanism operable to move the seal with respect to the channel portion between a retracted position and an extended position in which the seal is configured to contact the underside of a door mounted within the doorway.

Abstract: A threshold seal apparatus for a doorway, the threshold seal apparatus comprising a floor-mountable channel portion, a seal configured to be received within the channel portion, and an actuation mechanism operable to move the seal with respect to the channel portion between a retracted position and an extended position in which the seal is configured to contact the underside of a door mounted within the doorway.

Abstract: A clamp comprises: a first jaw (2) and a second jaw (3) having opposing contact surfaces (8, 9) which are relatively substantially linearly displaceable between a position of minimum separation and a position of maximum separation, wherein in use the opposing contact surfaces (8, 9) contact the lower surface and upper surface respectively of a structural element, wherein the first jaw (2) incorporates a first aperture remote from the contact surface and adapted to receive a suspension element or fastener; one or more means for guiding the first jaw (2) and the second jaw (3) during relative substantially linear displacement such as to substantially prevent relative non-linear displacement of the opposing contact surfaces (8, 9); and means for delimiting the substantially linear displacement of the opposing contact surfaces (8, 9) of the first jaw (2) and second jaw (3) to the position of maximum separation.

Abstract: A blind fastening method and device for use in clamping a component to a support plate, in which the fastener device is taken through aligned openings in the component and in the support plate, and comprises: a slotted sleeve; an apertured sleeve head at one end of the sleeve; a threaded fastener portion which can be taken through the apertured sleeve head and the sleeve; a tightening fastener head for tightening the fastener portion; and a diverging sleeve-expanding head mounted on the fastener portion and engageable with the opposite end of the sleeve to expand the latter radially outwardly to anchor the sleeve; in which the sleeve head has an off-set formation engageable to a tool which prevents rotation of the sleeve head while the fastener head is being tightened.
