IPC: G02B23/12
Abstract: 1,052,325 Modulating light by light. GRETAG A.G. June 24, 1965 [June 25, 1964], No. 26840/65. Heading H3R. In an infra-red to visible image transducer, incident infra-red rays 1 pass through a grating 2 and a sensitive layer 3 to a transparent base 4, Figs. 2 and 3, where they are entirely absorbed. Base 4 has a low heat conductivity and high absorption properties for rays in the far infra-red, i.e. 3Á-100Á, and may comprise a polyester, a metacrylate or an epoxy resin. The incident radiation is stored in the base 4 as local heating and causes a change in the surface tension of the sensitive layer which results in troughs in the sensitive layer at the irradiated places, grating 2 creating temperature gradients. Sensitive layer 3 comprises a thin film of a low viscosity liquid such as one of the hydrocarbons decane, hexane or octane, and has a thickness of 0À2Á to 10Á, the ratio of the grating interval to the thickness of the sensitive layer being between 100 and 300 (the grating interval being the width of a gap and bar in a bar and slot grating or the diameter of individual lens in a lens grating, Fig. 4 (not shown). With a lens grating the sensitivity is doubled. The resulting deformations in the sensitive layer 3 are made visible by means of a light source 8, Fig. 3, a prism 7, a lens 9 and a Schlieren optical system 10, the deviation of the reflected light from layer 3 being dependent on the deformations produced in layer 3. A phasecontrast optical system may be used for making visible the deformation in the sensitive layer instead of the above optical system. With this arrangement the interval at which two subsequent images can be observed may be <SP>1</SP>/ 20  sec.

Abstract: 1,226,359. Inking apparatus. COLUMBIAN CARBON CO. 25 July, 1968 [31 July, 1967], No. 35669/68. Heading B6C. The shaft 4 of each rotatably-mounted forme-inking roller 1 is carried by brackets 3 pivoted at 5 and connected to a link 8 rotatably mounted on an eccentric 7 keyed to a shaft 6 journalled in the main frame 24, mechanical means being provided to rotate the shaft 6 so as to move the roller 1 into contact with or away from the forme-cylinder 2. As shown, the pivbt 5 is the axis of a vibrator roller 15. To rotate the shaft 6, a push rod 13, movable between predetermined positions and operated by an air cylinder 14, is connected by a link 10 and lever 11 to a block 9 fixed to the shaft 6. To adjust the operative and inoperative positions of the roller 1 and therefore the pressure of the roller 1 against the cylinder 2, the shaft 6 may be rotatably adjusted in the block 9 by means of a worm-and-worm wheel device 21, 20, Fig. 3, thus adjusting the eccentric Y. In an alternative arrangement, Fig. 6 (not shown) an arm keyed to the shaft 6 is engaged by bolts threaded into the block 9, the arm and shaft being adjusted relatively to the block 9 by means of the bolts. Misalignment of the roller 1 i.e. non-parallelism with the cylinder 2, may be corrected by the arrangement shown in Fig. 3, wherein the shaft 6 comprises two parts 6a, 6b. The part 6b is connected to the block 9 and has keyed thereto an eccentric 7b engaged by the link 8 at one end of the roller 1. The other part 6a has keyed thereto an eccentric 7c engaged by the link 8a at the opposite end of the roller 1, and also has keyed thereto an eccentric part 7a which is adjustably connected to eccentric 7b by a bolt 17. By adjustment of the bolt 17, the eccentric 7c may be moved relatively to the eccentric 7b to correct misalignment. In order to allow of the required skewing movement of the roller 1, its shaft 4 is, at one or both ends, mounted in the brackets 3, 3a by spherical bearings 30. The shaft 4 of the roller 1 may have eccentric parts 18 whereby, by loosening bolts 19 on the brackets 3, 3a, the shaft 4 may be rotated to adjust the pressure between the rollers 1, 5.
