Patent GB-2063178-A (GB)
Title: Registration of colour and embossment by an ink-coated release medium
IPC: B44C5/04
Filed: 1980-10-15
Abstract: There is provided a method of producing a decorative laminate of contrasting colour in response to embossment during the lamination operation wherein its decorative surface protrusions are of a colour different from the background colour of the laminate. To accomplish this result, the release sheet in an otherwise essentially conventional arrangement of superimposed laminae has an ink layer on the surface thereof adjacent to the decor sheet so that during the heat and pressure consolidation of the laminae with an embossing press plate the ink layer is transferred to the adjacent surface of the decor sheet, or of the overlay sheet if such is present. Subsequently, the surface of the resulting laminate is burnished to remove the ink from the high areas of its embossed surface.

Title: Back-lighting arrangement for copying cameras
IPC: G03B27/62
Filed: 1980-11-10
Abstract: A back-lighting box for use with reproduction cameras, in particular reproduction cameras with wide angle objectives for illuminating transparencies, features a number of fluorescent tubes 11a to 11g arranged spaced apart in a plane and extending over a diffuse reflecting surface 12 the reflectance of which reduces from the outer regions towards the inner regions. The light radiated from the fluorescent tubes 11a to 11g and reflected from the diffuse reflecting surface 12 is directed through a diffusing plate 15 onto a transparency support surface 14. As a result of the reflecting characteristics of the diffuse reflecting surface 12 it is possible to achieve a greater illumination of the transparency support surface 14 at its edges than at its centre and this is precisely what is required for wide angle objectives. <IMAGE>
