Abstract: A control joint device including a reciprocating means, a surface breaking member and a ridge member having a generally flat bottom surface except for a first ridge along, at least, a portion of its length, wherein, in use, the first ridge of the ridge member is positioned behind the surface breaking member, the surface breaking member is mechanically reciprocatable in a straight line between a first position and a second position along an axis substantially perpendicular to the plane of a setting material, the first position being substantially level with the first ridge of the ridge member and the second position being spaced apart from the first position and wherein the ridge member further includes a planar surface from which the first ridge extends.

Abstract: Apparatus for releasing tablets from a blister pack (3) having a plurality of tablets (41) contained in corresponding blisters (40), the apparatus comprising abutment means (30), receiving means (10, 26) for receiving a blister pack with any selected one of a plurality of blisters of the pack in registry with the abutment means, either one of the abutment means (30) and the receiving means (10, 26) being moveable to cause a collapsing force to be exerted on a selecting blister thereby to release a tablet from the blister, wherein the apparatus includes biasing means (14, 20) for urging the receiving means into engagement with the blister pack, and that the receiving means is so arranged that said engagement releasably retains, and locates, the blister pack in position relative to the abutment means prior to the release of the tablet.

Abstract: Apparatus for releasing tablets from a blister pack containing a plurality of tablets, each held in a respective blister, the apparatus comprising receiving means for receiving a blister pack, the receiving means having a lid moveable between an open and a closed position, the apparatus further comprising an abutment member mounted on the lid, the arrangement being such that movement of the lid from the open to the closed position, in use, causes the abutment member to engage, and release a tablet from, a blister in registry with the abutment member.

Abstract: Apparatus for releasing tablets from a blister pack (34) containing a plurality of tablets, each held in a respective blister, the apparatus comprising receiving means (1) for receiving the blister pack so that the pack is moveable on the receiving means (1), and an abutment member (32) moveable into engagement with the blister in registry therewith so as to eject the tablet from that blister, wherein the apparatus includes indexing means (28, 30) for moving a blister pack (34) on the receiving means (1) to bring each of a succession of blisters in turn into registry with the abutment member (32).
