Abstract

1378953 Clamps PINTSCH BAMAG ANTRIEBS-UND VERKEHRSTECHNIK GmbH 29 Feb 1972 [27 March 1971] 9366/72 Heading E2B [Also in Division F4] A clamping arrangement for securing together a number of coaxially aligned annular lens segments 1, 2 to form the cylindrical body of a light source drum lens comprises top and bottom guide rings 3, 4 which are interconnected by tension rods 10 extending within the body when assembled to axially compress the guide rings and lens segments together. As shown, tension rods 10 having thickened end portions engage bores in respective clamp elements 5 which are adjustably fastened onto the guide rings by two screws 6. The tension rods 10 may be curved in the free state to produce initial tension in the clamping device.
