Abstract: Apparatus for applying sheet material to framework elements comprises elongate support means for sheet material and means for attachment of said support means to framework elements, in which the elongate support means comprise a base member having upstanding stud members for engagement in use with pre-formed holes formed in the sheet material and a capping member for applying over said base member to apply out-of-plane tensioning deformation to said sheet material, in which the capping member includes groove formations for receiving the edge of sheet material formed as a keder.

Abstract: A handheld inspection apparatus for inspecting an object in a non-contact manner is provided, the apparatus comprising: a telecentric lens arrangement comprising a telecentric lens arranged to collect light rays projected or reflected from an object to be inspected; a mobile image sensing device such as a CCD digital camera arranged with respect to the telecentric lens to receive the lights rays collected by the telecentric lens and convert these into an image representative of the object, wherein the telecentric lens is arranged such that movement of the apparatus in a direction away from or towards the object causes the image to remain of the same size on the image sensing device. Preferably an illumination unit is provided which is detachably mounted on the camera and is interchangeable depending on the purpose.
