Abstract: The present invention is directed roof edge seal and barrier devices and their method of manufacture. A method of manufacturing a comb-like sealing strip for use as a roof edge seal or barrier comprises stamping or cutting an elongate strip of material along a sinuous path located between the edges of the strip and then separating the strip into two portions, each of which consists of a fixing edge corresponding to the edge of the original strip from which project a series of teeth or prongs forming a comb structure.

Abstract: Two-part tags for attachment to a sheet form material (17), for example the cloth of a garment, are described. Each tag consists of a first part (1) adapted to carry a legend and having a substantially flat surface to lie against the sheet form material when the tag is used, and a perpendicularly projecting member projecting from the flat surface, and a second part (2) having a flat surface adapted to lie against the other side of the sheet form material when the tag is used, the second part including a receiving hole adapted to receive and hold the projecting member on the first part. The projecting member is a rod with a cone (4) on its end remote from the flat surface of the first part, the broadest part of the cone being of greater diameter than the remainder of the rod. The hole in the second part has a first section of diameter less than that of the wider end of the cone and a second section of diameter at least equal to that of the wider edge of the cone.

Abstract: Walking aids are described which are of simple construction but which allow for both resilience, i.e. the part of the walking aid which is gripped by the user and the ground-engaging end (3) can be resiliency pressed together, as well as a degree of angular flexibility so that the end (3) stays aligned with the ground even if the stick, crutch or the like (1) is angled relative thereto. This is achieved in particular by the use of a bellows structure (2) between the shaft (1) of a walking aid and a ground-engaging foot (3).

Abstract: Apparatus for introducing a liquid into a sealed external container or a sealed external system, the apparatus having a bellows which is sealed a first end, which is sealed at a second end solely by a valve, and which contains the liquid; wherein the valve is one which is positioned remote from the first end of the bellows, which retains the liquid in the bellows, and which permits liquid flow only in a direction from the apparatus to the sealed external container or the sealed external system; and wherein the apparatus further has a connector which in use forms a sealed connection between the apparatus and a sealing valve on the sealed external container or the sealed external system.

Abstract: Apparatus (2) for causing fluid flow, which apparatus (2) comprises a bellows (4). The bellows (4) may be made of a metal or a plastics material. The bellows (4) may include sealing means (10) for sealing the fluid in the bellows (4) and/or preventing air entering the bellows (4). The apparatus (2) may include connector means for connecting the apparatus.

Abstract: A display device includes a generally planar upper surface. The upper surface has at least two upstanding walls, each wall having a profiled edge for receiving and supporting a generally cylindrical object. At least one of the walls is removable from the upper surface.
