Abstract: A launcher is disclosed having means for directing and concentrically spreading, as well as dispersing, exhaust gases created by an internal combustion of an object, such as a missile, that is operatively launchable therefrom. The concentric duct provides the directing, spreading and dispersing means and cooperates with a cup having means to arrange a port in operative relationship with an exhaust outlet of the object being launched. The cup which mates with the concentric duct has one of its ends open to the ambient so that the exhaust gases are lead into and out of the concentric duct so as to be concentrically dispersed into the atmosphere.

Abstract: A conveyor conveys first and second plates to an exposure station. First and second laser imagers mounted at the exposure station above the support generate first and second laser beams adapted to sweep over the first and second plates, respectively. A mechanism effects simultaneous relative movement between the first laser imager and the first plate and between the second laser imager and the second plate. A computer system receives source image data corresponding to first and second source images, which correspond to first and second print images to be formed on the first and second plates, respectively. The computer system generates a first set of electrical signals corresponding to the first source image which are provided to the first laser imager, and generates a second set of electrical signals corresponding to the second source image which are provided to the second laser imager.

Abstract: Apparatus for exposing photosensitized plates to light through films. The apparatus has an infeed end, an outfeed end forward of the infeed end, opposite sides, an exposure station forward of the infeed end at which a plate is exposed to light through a film, and a carriage for carrying plates and films in a forward direction from a loading station at the infeed end of the machine to the exposure station. The apparatus includes a support for supporting a stack of plates at one side of the apparatus generally adjacent the infeed end of the apparatus. A conveyor system conveys a plate in side-to-side direction with respect to the apparatus from the one side of the apparatus to the loading station. A transfer mechanism removes a top plate from the stack of plates and transfers it to the conveyor system for conveyance to the loading station.

Abstract: Lithographic plates have an identifying folio and an image thereon. The image corresponds to a print image to be printed on sheet material such as newspaper stock. An image camera optically examines the identifying folios of each of the lithographic plates to ascertain folio information, and optically examines the images of each of the lithographic plates to ascertain image information including registration information and exposure information. A CPU records in an the electronic memory the ascertained folio information of the identifying folio of each lithographic plate and records in the electronic memory the corresponding ascertained image information of the image of each lithographic plate. An operator using a keyboard can access the image information of a particular plate recorded in the electronic memory by reference to the corresponding recorded folio information for the particular plate whereby the folio information and the image information are cross-referenced.

Abstract: Apparatus for bending a lithographic plate having an image thereon, comprising an inspection system for (a) inspecting a plate held on a table at an inspection station, (b) determining the extent to which the plate needs to be adjusted relative to a predetermined reference position, and (c) generating a signal indicative of any such adjustment. A first positioning mechanism responsive to the signal automatically moves the table to position a plate on the table for a bending operation.

Abstract: Method of and apparatus for punching and bending a lithographic plate to match a particular press so that when the plate is subsequently mounted on that particular press, it is oriented to print a properly positioned image on a print surface.

Abstract: Automated apparatus and method for exposing lithographic plates to light through films and masks. The method involves placing a plate, film and mask at an exposure station in superposed relation to one another with the film overlying the plate and the mask overlying the film, exposing the plate to light through the mask and film at the exposure station, raising the mask off the film to a raised position, gripping the film and moving it relative to the plate to expose a portion of the plate therebelow, gripping the exposed portion of the plate, gripping the mask in its raised position, moving the film, plate and mask forwardly while so gripped to a discharge station, and releasing the film, plate and mask at the discharge station.

Abstract: Apparatus for exposing photosensitized plates to light through films, having a window movable up and down at an exposure station adapted to grip a film after an exposure of a plate and to lift the film away from the plate, plates and films being fed in under its raised window from a loading station, films being discharged from the bottom of the raised window to a tray located above the loading system in a position wherein it does not interfere with manual loading of plates and films in the apparatus.

Abstract: A method of automatically inspecting an exposed and bent lithographic plate having an image thereon to determine whether the image is in proper registration relative to the plate. The plate has front, rear, and opposite side edges.

Abstract: Laminated composites made with layers of fiber reinforced thermosetting resin prepregs and with thermoplastic film interleaf layers are improved by using thermoplastic film coated with thermosetting adhesive as the interleaf layer. In composites having a honeycomb core with thermosetting prepreg skins, the thermoplastic film is a moisture barrier to exclude water vapor from the honeycomb cavities.

Abstract: A method for construction of an in-ground swimming pool includes the steps of excavating a hole with a wall, providing a shelf associated with the wall and installing a footing form structure with a form member in association with the shelf. The footing form member is leveled and a concrete footing is poured in a footing form volume defined by the wall, the shelf and the form member. Wall form panels are placed on the footing and a concrete wall is poured therebetween.

Abstract: An apparatus for exposing boards which are photosensitive on both sides, for production of printed circuits on both sides, to light through films on both sides in which a lower film, a board, and an upper film in registered position on a light-transmitting platen are pressed down by a window and exposed to light on both sides through the platen and window. A pair of registration pins are adjustably positioned in spaced relation along an edge of the platen and corresponding holes in the boards are used to align the boards and films for exposure. The pins are spaced as widely apart as possible to provide maximum registration between boards of varying sizes and films.
