  • Patent number: 5136323
    Abstract: Apparatus for treating a web with a fluid comprises means defining an elongated channel for receiving the web. The fluid is injected into the channel on opposite sides of the web at one or more injection sites. Fluid is evacuated from the channel on opposite sides of the web at one or more evacuation sites. Each injection site is located between two evacuation sites and spaced therefrom such that fluid will flow in opposite directions from the injection site to the adjacent evacuation sites with laminar flow and be evacuated from the channel when the boundary layer of the fluid reaches a predetermined thickness.

  • Patent number: 5093678
    Abstract: A processor for photosensitive material provides a processing solution to a processing chamber while the photosensitive material is advanced through the chamber.

  • Patent number: 5089078
    Abstract: A polygon of a laser optical system is supported by a housing and requires precise alignment with respect to a base for proper operation of the optical system. A fixture has a base that is mounted for rotation about an axis. A plurality of adjustable pad assemblies are located between the base and the housing. Each pad assembly includes a mounting plate that is positioned on the base and a bushing that is secured to the housing. A compressible ring surrounds a surface on the plate that receives an adhesive. Pushers carried by the base engage the housing and urge the housing toward the base. The pushers are individually adjustable to control the position of the housing relative to the base about a plurality of axes. An optical instrument measures the angular position of the optical device on the housing and, when it is properly positioned, it is held until the adhesive cures to bond the mounting plate and bushing together.

  • Patent number: 5080345
    Abstract: A registration mechanism registers sheets of different sizes so the sheets are properly positioned as they enter an imaging station adjacent the mechanism. A fixed urging guide at one side of a platen urges sheets of the largest size toward a registration guide at another side of the platen for aligning the sheet relative to the guide. Other urging guides move through slots in the platen between a raised position relative to the platen, wherein they are effective to urge smaller sheets toward the registration guide, and a lowered position at or below the platen surface.

  • Patent number: 5073916
    Abstract: Method and apparatus for use in X-ray cassette unloading and loading apparatus, including novel detection of presence or absence of film in the cassette and the position thereof in the upper or lower cassette part, utilizing radiation, such as infra-red, to which the film is not sensitive. Radiation is directed into each cassette part after opening and the radiation reflected from the respective parts is compared. The radiation means, as well as means for holding the cassette parts in open position and air jet means for releasing film from the upper cassette portion, are all mounted on parallelly moving guide members which engage the lateral edges of the cassette to position it.

  • Patent number: 5065173
    Abstract: An automatic film processor sets new reference developer chemical temperatures and film transport speeds in accordance with user input at a keypad and establishes a new delay time to provide constant fixed spacing along the transport path between trailing edge of one film sheet and leadfing edge of a next film sheet regardless of transport speed. "Wait" and "ready" lights are controlled to signal when a next sheet is to be fed. A microcomputer calculates the delay time and loads a counter. A buzzer signals countdown to zero.

  • Patent number: 5059997
    Abstract: Apparatus for processing photosensitive material includes upper and lower tanks for a processing solution. The tanks are connected together so that the solution can flow freely from the lower tank to the upper tank. The photosensitive material is advanced through a processing chamber between the tanks while the solution in the upper and lower tanks is provided to the chamber. A sump holds a supply of the processing solution, and a pump is coupled to the sump to draw the solution from the sump. The pump also is connected to the lower tank so that the processing solution is delivered to the lower tank, and from the lower tank some of the solution is furnished to the upper tank.

  • Patent number: 5048686
    Abstract: A package has a light tight pouch that encloses a stack of rectangular sheets of film. The package can be loaded in either of two different kinds of equipment which have means for removing the pouch from the film stack so that the sheets can be fed seriatim from the stack. One kind of equipment requires the package to be oriented so that the pouch can be removed from a narrow side of the package while the second kind of equipment requires the package to be loaded therein so that the pouch can be removed from a long side of the stack of film. The pouch has flaps extending from one long side and one narrow side of the package, and the flaps are engageable by the pouch removing mechanism in the different kinds of equipment.
