Abstract: A tensioning frame (22) for tensioning a printing screen (3) comprises a plurality of elongate beams (30A-30D) which extend around the periphery of the printing screen (3) and define the tensioning frame (22), wherein at least one of the beams (30A-30D) comprises an opening (32) which is dimensioned to permit a printing screen (3) to be received therethrough, in a lateral direction (A). Mechanisms are described for engagement of the tensioning screen (22) and printing screen (3), as well as an apparatus and a method permitting the lateral loading of the printing screen (3).

Abstract: A tensioning frame for tensioning a printing screen comprises struts to reinforce the constituent beams. These may be provided either on a supplementary brace plate or integrally formed with the beam. A shaft may be used to retain engagement bodies within pockets formed in the beam.

Abstract: A vape tool comprises a coiling rod 114, and a coiling tool 94 for engaging with and rotating around the coiling rod 114, the coiling tool 94 having a housing 96 with a substantially conical inner wall, a collet 106 disposed inside the housing 96 and arranged to bear against the inner wall, an internal diameter of the collet 106 being determined by the longitudinal position of the collet within the housing and a control means 112 for controlling the longitudinal position of the collet 106 within the housing 96. The tool 94 forms part of a vape tool kit (10, FIG. 1) including a four part housing for housing a tool barrel (22, FIG. 1), a spool (44, FIG. 1) and a sealable container.

Abstract: An additive unit for a central heating or hot water system is connected in line to conduits of the system. The additive unit comprises a chamber having an inlet connected to a first conduit and provided with a valve, and an outlet connected to a second conduit and provided with a valve. The chamber is provided with a drain tap and an access port with a closure cap. A bypass conduit extends through the interior of the chamber. The inlet valve and the outlet valve switch flow from a normal route through the chamber to a bypass route through the bypass conduit. Fluid isolated in the chamber can be removed via a drain tap and an additive/top up fluid introduced via a port. Normal flow can then be restored by operating the valves.

Abstract: Camouflaged garments of the type used by hunters, outdoorsmen and the like. Particularly, a garment having a plurality of elongated connectors secured at each end so as to form connector loops extending outwardly of the garment. The camouflage element consists of a pair of simulated leaves having a common stem, such that a simulated leaf extends from each end of the stem. The stem is flexible so that it may be interlocked with the connector loop and thereby releasably support the simulated leaves on the outside of the garment. The leaves are characterized by their simplicity of construction and the ease of interchangeability depending upon the change of seasons or habitat.
