Abstract: 100,695. Johns-Manville Co., H. W., (Assignees of Rewell, F. F.). June 16, 1915, [Convention date]. Portable pressure reservoirs. - A hand fire - extinguisher of the kind in which liquid is ejected by compressed air is so arranged that, in all positions, liquid may be ejected from the nozzle and air is prevented from passing thereto so long as any liquid remains in the apparatus. The apparatus comprises a casing 5, the upper part 10 of which forms a compressed - air reservoir supplied by means of the pump 14 and communicating with the liquid reservoir through the non- return valve 27. The liquid passes to the regulable exit nozzle 31 through a valve casing 54 and passage 39, so arranged that, in whatever position the apparatus is held, the liquid is delivered from the part which at that time is lowest. For this purpose, the valve casing 54 and pipe 39 are mounted on the swivel coupling 40 and ring 56, so that they rotate about the axis of the apparatus. The casing 54 carries a weighted rod 51 having a mushroom valve 49 at each end arranged to close whichever opening 50 is uppermost and simultaneously open the lower one, liquid thus being discharged through the passage 45 or 46, whichever is lower. The regulable nozzle 31 mounted on the concave head 29 is formed with square threads 35, which engage the square-threaded nut 34, and is formed with a valve seat 36 at its rear. On being rotated by the handle 37, the nozzle may be screwed forwards in order to open the passages more or less. When not in use, the nozzle is held closed bv means of a seal attached to the lugs 59, and the pump handle is held in the inoperative position by means of the lug 26 engaging the lug 25.

Abstract: 1,038,786. Colour projection printer. AGFA A.G. March 5, 1963 [March 6, 1962], No. 8765/63. Headings G2A, G2C and G2J. A light conducting device for use in a colour projection printer has a light passage therethrough, and a transverse light collecting surface surrounding said passage, such that light incident on said surface is canalised in said transverse direction. In the form shown, light from three lamps 14, 15, 16 passes through red, green and blue lens-filter arrangements respectively, and then passes, via semi-reflecting mirrors 17, 18, 20 and lenses 19, 21, 22, 23 through a transparency 24. An image of this transparency is projected by a lens 32 on to a light-sensitive strip 3. Just below the carrier 33 of lens 32 is a photometric device in a housing 34, comprising a light-conducting plate 38. This has an aperture 45 coaxial with lens 32, and further apertures 46, 47 are provided in the lower and upper plates 48,49. Aperture 46 is larger than aperture 45, so that a region 50 of the plate surrounding aperture 45 is not covered by the base plate, and serves as a light-collecting surface for "secondary" light, that is, light passing through the transparency which does not pass through lens 32 to be utilized for the production of an image. This "secondary" light is transmitted by internal reflection along the plate 38 to three photocells 39, 40, 41, respectively red, green, and blue sensitive. These cells control by electromagnetic means louvre shutters 28, 29, 30 in front of the respective lamps 14, 15, 16, and close the shutters when a predetermined amount of light has fallen on the particular photocell. A forked plate 51 can slide adjustably along the underside of base plate 48, and so vary the marginal area 50 exposed as a light-collecting surface. The aperture 45 in plate 38 may be dispensed with, as long as the other apertures 46, 47 are retained. The plate 38 may be constituted, in the area round the projection beam, so as itself to form the projection lens 32. The photometric device may be used also in black and white printing apparatus, to control image brightness in projectors.
