Title: Optical projection apparatus
IPC: G03B23/18
Filed: 1971-08-04
Abstract: 1337318 Optical projection apparatus HONEYWELL Inc 4 Aug 1971 [14 Aug 1970 (2)] 36724/71 Heading G2A A projection apparatus having two projection paths includes a movable reflecting device which changes the image projected on to a screen by reducing the image intensity of a first object and increasing that of a second. As shown in Fig.1 a lamp 2 provides light for identical optical systems 3L, 4L, 5L and 3R, 4R 5R. The lenses 5L, 5R both focus an image of the filament 44 on the node 43 of objective lens 38. -The movable reflecting device includes pinion 35, rotated by control 36, which engages racks 8L, 8R, 25 bearing mirrors 19L, 19R and 31L, 31R respectively. Rotation of the pinion 35 moves racks 8L, 8R, 25 along the line of their slot and pin mountings. As shown the left hand optical system provides the image on the screen 41; however as the pinion 35 rotates clockwise the rack 8L rises, 8R falls and 25 moves to the left. The projection paths of the left and right optical systems thus eventually become the reverse of that shown. During this changeover, light from both systems is partially incident on the mirrors 31L, 31R. Because the systems focus an image of the element 44 on the node 43, the images of the slides 7L, 7R are not coherent at this point and so images of reduced intensity of the slides 7L, 7R are passed to the objective 38. Hence a constant screen intensity is maintained during the changeover. A modified apparatus in Fig.5 has fixed mirrors 119L, 119R in place of movable mirrors 19L, 19R and sliding mirrors 131L, 131R, whose alternative positions are indicated by 132L, 132R, in place of mirrors 31L, 31R. The mirrors 131L, 131R have reflecting surfaces on both sides so that an image of the slide not being shown on the screen 41 is supplied to a previewing device 134, 135. Mechanisms for sliding the mirrors 131L, 131R are disclosed and in other embodiments the apparatus of Fig.5 is modified so that the mirrors 131L, 131R are placed one above the other and perpendicularly to each other and are moved in plane perpendicular to the Fig. In another modification two lamps and optical systems which are not folded except at the moving reflecting device are used. The projectors may use slides or film strip or be cine projectors.

Title: Improvements in or relating to epoxide resins
Inventor: DOBINSON BRYAN
IPC: C08G59/16
Filed: 1964-09-10
Abstract: The hydroxyl group content of an OH group containing epoxy resin is reduced by reaction with a cyclic or acyclic vinyl ether of formula <FORM:1105747/C3/1> in which R and R1 each represent either H halogen or alkyl radicals; R may have the same meaning as R and R11 when R111 represents a monovalent alkyl, aralkyl or aryl radical or alternatively R and R111 taken together may represent a divalent aliphatic group, e.g. a C2-C3 polymethylene chain.  A preferred vinyl ether is 3,4-dihydro-2H-pyran.  Reaction is effected in the presence of a small quantity of an acid catalyst, e.g. HC1, so that the hydroxyl groups but not any substantial proportion of the epoxy groups react with the vinyl ether. The vinyl ether is preferably more volatile than the epoxy resin and any excess may be distilled off after reaction.  The product may be cured with conventional epoxy resin hardeners.
