IPC: G03C7/14
Abstract: 482,690. Copying lenticular films by projection. LASSUS ST. GENIES, A. H. J. DE. June 1, 1937, No. 15149. Convention date, June 10, 1936. Addition to 470,801. [Class 98 (ii)] Apparatus for copying lenticular films by projection in which screens or screen systems having slots are displaced homothetically in front of the two films so as to illuminate thereon narrow and parallel homologous sections is characterized in that an additional movable screen having a window which is adapted to coincide with the illuminated section of the film and which has a glass segment or plurality of plates with parallel faces arranged at different inclinations therein is displaced adjacent at least one of the films. As shown in Fig. 2, 0 is the copying objective, F<1> the copy film, R<1> a movable screen having a slot S<1> which illuminates a zone H<1> of the film, and R<11> another movable screen, the aperture of which coincides at any moment with the zone H<1>. In the window of the screen R<11> are mounted a cylindrical glass W<1> and an optical system U<1>. The moving glass W<1> effects relative movement of the lenticulations of the original and copy films to eliminate moirÚ. The optical system U<1> increases the aperture of the elementary beams recorded on the copy film. The glass W<1> may be calculated to compensate for image movement introduced by movement of the optical system U<1>. The optical system U<1> may, in a modification, comprise two prisms and a parallel-faced glass, and the glass W<1> three parallel-faced glasses, the outer two of which are inclined to the middle one. The moire may be eliminated by allowing an error in the compensation produced by the glass W<1> equal to the pitch of the lenticulations. As shown in Fig. 4, D is a screen delimiting the active surface of a light source of width d, and the objective O has a diaphragm D<1>, the aperture of which coincides with an image of the active surface d. R, R<1> are movable screens provided with slots S, S<1>. Auxiliary lenses A, B are provided on opposite sides of the original film F. U is an auxiliary optical system comprising prisms or lenses inserted into a screen R, movable transversely to the lenticulations of the film F. The system U is provided to ensure correct illumination of the lateral partial components of the film F. A correcting system Ul is displaced simultaneously with U, but on the opposite side of the film F. The glass W<1> and the optical system U<1> are employed as in Fig. 2. The use of the optical systems U, U<1> and Ul may be rendered unnecessary by bending the films on the zones H and H<1> illuminated at any moment orthogonal to their lenticulations. As shown in Fig. 6, F and F<1> are the films lenticulated transversely, in transverse section, and a plane or Mangin mirror M is placed behind the objective O. The slots Sand S<1> may be fixed and the films F and F<1> may be moved continuously, as by two sprockets on a common shaft.

A portable contact printing apparatus comprises a heater unit 10 and an exposure unit 11, the latter having an open side defining a generally rectangular exposure area and containing an internally reflective surface 49 supporting a lamp 54 and a reflector 55. No light from the lamp falls directly on the exposure area, but is reflected on to the area by the surface 49, or by the reflector 55 and the surface 49. A relationship between the length of the longest side of the area, the maximum height of the reflective surface above the area and the height of the lamp above the area such that no light reaches the area directly from the lamp is given. The exposure unit is stored on top of the heater unit 10 which latter unit carries a heating platen (14), Fig. 3 (not shown) and means (22) (23) for heating the platen by radiation and convection. To make a copy, the two units are separated and a resilient pad (35) and pressure plate (36) removed from the base 13 of the unit 10. The units are connected to a suitable electrical supply and the unit 11 adjusted for the correct exposure time. The unit 11 is placed over a sandwich consisting of, from bottom to top, the pad (35), the printed page to be copied, a sheet of sensitized film, and the plate (36), and the exposure is made, the unit and plate being removed as soon as the lamp 54 is extinguished. The exposed film and a sheet of reactive paper are then held against a screen (17) which is lowered into contact with the platen (14) for a suitable length of time. As the exposure unit is removed from the sandwich, air will flow through holes in the unit to cool the lamp.

Abstract: 1,165,905. Gas cooling installations. STONE & WEBSTER ENG. CORP. 11 Nov., 1966 [13 June, 1966], No. 50698/66. Heading F4S. In a fluid cooling process, intended for the cooling of hot gases from the hydrocarbon cracking process described in Specification 1,165,906, the fluid is cooled in an annular chamber which at the inlet end thereof increases in cross-sectional area per unit length such that the outlet pressure of said fluid is substantially the same as the inlet pressure to said chamber. Preferably the area increase is equal to the increase in cross-sectional area of a conical pipe having an angle of divergence of from 4 to 7 degrees. In the gas cooling process described, the hot gases at from 1350‹ to 1650‹ F. are introduced into the annular chamber at about 700 to 800 feet/sec. and are cooled therein in about 1 to 30 milliseconds to about 1200‹ to 1400‹ F. The gas cooler shown comprises concentric tubes defining an annular coolant passage 33 arranged within an annular passage 35 for the gas to be cooled. This latter passage includes conical members 38, 39 at the gas inlet end 40 of the passage, together providing the required change in cross-sectional area at the passage inlet. The cooled gas is discharged through an outlet 44. Coolant (e.g. water) enters at 73 and is discharged (e.g. as steam) at 75. Other coolant means may as shown comprise spaced-apart tubes 67 arranged around the gas passage 35 and in close contact with the outer wallsurface thereof. The tubes extend between coolant inlet and outlet annular headers 49, 50 and the spaces between adjacent tubes (see Fig. 2) are filled with a heat conducting material (unspecified).
