Title: Device for one by one optically transferring and taking up of images
IPC: B41B21/16
Filed: 1975-12-17
Abstract: 1512830 Photocomposing apparatus E B PLOOIJ 17 Dec 1975 [20 Dec 1974] 51621/75 Heading B6W To arrest the moving image of a related character in a rotating-drum-matrix photocomposing apparatus a rotatable mirror 6 is situated in the optical path from drum to stationary film 22. When a character is selected from matrix ring 1 or 11 by energizing light source 2 or 2<SP>1</SP> the moving image of the character is directed upwardly through prisms 14 and 15 or 16 and 17 to lens 3<SP>1</SP> or 3 and onto mirror 6. The mirror is then coupled to move with the drum over a predetermined arc by raising of a pin 20 (corresponding to the selected character) into the path of an arm 19 coupled to the mirror. Thus the moving images held stationary relative to film 22 and the characters imaged at exposure opening 24 through shutter 25. A spring returns the mirror to the starting position. Three matrix rings 1, 1<SP>1</SP> and 1<SP>11</SP>, Fig 4, may be employed and movable prisms 32 and 33 used to select which ring is imaged.

In a gas laser the active medium is positioned in the hollow space of a cylindrical plasma. In one embodiment, Fig. 2, a laser tube 6 containing a gaseous mixture of neon and helium is positioned inside a TE 011  mode cylindrical resonator 1 supplied by microwaves from oscillator 2 and surrounded by coils 9a, 9b for producing a magnetic field. Due to the cyclotron effect a cylindrical plasma 10 is set up, the gaseous active medium in the space 11 thereof being excited by the microwave discharge and the resultant stimulated emission being resonated by mirrors 12a, 12b. Instead of using a cyclotron the plasma may be formed by a magnetron, Fig. 3, in which microwaves are supplied to two sets of electrodes 14a, 14c, 14e, 14g and 14b, 14d, 14f, 14h in order to cause local microwave discharges to occur between adjacent electrodes and a cylindrical plasma to be formed. Stimulated emission again occurs in the electrically neutral hollow space of the plasma.
