[Class 100 (ii)] [See Group XX] In dye-imbibition printing the perforation gauge of the underlying film is made slightly longer than that of the overlying film in its untensioned state and the films are so fed together through a, comparatively long printing zone that the portion of the overlying film which at a given moment is within the printing zone is given a greater tension than the corresponding portion of the underlying film. As shown applied to photographic contact-printing, the films 9, 11 pass from spools 10, 12 over the wheel 4 to the take-up spools 23, 13. The film 11 has the longer perforation gauge, and both films pass over a braked sprocket A and an electrically driven sprocket B. The film 9 engages sprockets A, B over a larger portion of their circumference than the film 11, and also engages a driven sprocket 17. The wheel 4 is driven by frictional engagement with the films and has a transversely concave surface. The temperature of the wheel is regulated by a device 24. The films may be moved intermittently, and more than two films may be employed. Specification 447,983 is referred to.

Title: Information storage and retrieval n1314905monsanto co olefin oxidation catalyst
IPC: G03G15/22
Filed: 1970-05-20
Abstract: 1314904 Line printers ENERGY CONVERSION DEVICES Inc 20May 1970 [29 May 1969] 24406/70 Heading G4H [Also in Division H4] A data printer comprises a drum 16, the surface of which is provided with a layer of memory material capable, when supplied with energy, of having discrete portions reversibly altered between conditions of high and low resistance. The memory material is a semiconductor which has a high resistance amorphous state and a low resistance state in which it is more ordered towards a crystalline structure. Data from a punched tape, magnetic tape or punched card is fed to a computer 18 which supplies instruction data to a memory 21 and print out data to a memory 23. The memory 23 is connected via a data translator 25 and a shift register 27 to a control 30 for a laser diode 32. A synchronous motor 38 rotates a mirror 40 so that the laser beam, which is pushed by short duration pulses from the shift register, scans across the drum 16, thereby changing discrete areas of the memory layer which recieve the beam from low to high resistance. At the end of each scan line, as detected by a photo-electric device 50, 52 which sends a signal to a motor control 22, a motor 14 steps the drum by a distance corresponding to one line. To ensure that the signal from the control 22 has in fact caused the motor to step the drum, a sensor 26a and a comparator 28 are provided and prevent data from the shift register from being supplied to the laser until the drum is in position to receive the next line of data. Characters in the form of a number of dots comprising areas of high resistance are therefore produced on the drum and are charged by an electric charge generator 76, thereby attracting triboelectric particles 80 from a container 78. The particles are transferred to a paper surface 84 and are permanently fixed by a heater 86. All the characters on the drum may be erased by a builk erase device 70 or portions of the drum memory may be erased by directing long duration pulses from the laser on to the drum. Instead of using a laser beam, a spark discharge between a movable electrode and the drum may be used (Fig. 6, not shown).
