  • Patent number: 7912172
    Abstract: A programmable divider apparatus comprises a first divider, a second divider, a feedback control unit, and a plurality of control signals. The first divider provides a frequency division operation of division by at least three integers, the second divider is cascaded to the first divider to provide a frequency division operation of division by two integers. The feedback control unit is coupled to between the first divider and the second divider to provide a feedback control signal to selectively supply an output of the second divider to an input of the first divider. The apparatus control signals and the feedback control signal are used to execute the first divider or the second divider.

  • Patent number: 4786950
    Abstract: A device for inserting copier web materials and exposure web materials into an apparatus for the continuous exposure of this material. The web materials are moved by means of a belt conveyor (9) through an entry slit, formed by a pair of drive rolls (15, 16), through an exposure chamber (B) with a transparent plate (4), and finally are conducted to another pair of drive rolls (10, 13) disposed behind the exposure chamber (B). From there, they are brought into the region of a separation device (30), which separates the webs of the web material from one another. The web materials have positioning holes that can be aligned with one another. The register pins (26) can be inserted into or brought out from these holes. The register pins (26) are disposed on lifting devices (MZ) between the entry slit and the exposure chamber (B). The drive roll (16), which is one of the drive rolls forming the entry slit, is designed so that can be lifted away from the web material; the other drive roll (15) is mounted permanently.

  • Patent number: 4189231
    Abstract: Apparatus for continuously processing sheet or strip copy material fed from a horizontal plane having an endless belt conveyor for moving the copy material, a translucent rigid plate disposed in a plane inclined to the horizontal plane, a backing element gapped from and pressing the copy material against the translucent rigid plate during movement through an exposure compartment, two pairs of driving rollers disposed forwardly and rearwardly of the translucent rigid plate, the drive rollers of each of the two pairs of drive rollers having a drive gap disposed in the plane of the gap between the translucent rigid plate and the backing element, and an inclined guide strip for the copy material extending from the horizontal plane into the drive gap between the pair of drive rollers disposed forwardly of the translucent rigid plate. A continuous developing apparatus may operate on the copy material rearwardly of the exposure compartment.
