Abstract:
A paper mask produces even width borders on bordered photographic prints even if the unexposed photographic print paper is misaligned, angularly mistracking, or wandering in alignment through roll feeding, or if the width of the paper varies. The paper mask apparatus includes a base which is mounted on the paper deck of the printer and front and rear guides which are movably mounted to the base and have masking lips which overhang the longitudinal edges of the print paper. The front and rear guides are generally parallel to one another and are urged toward one another by bias springs. A separate masking frame of the desired print size is mounted to one of the two guides and moves with that guide to define transverse masking edges.
Abstract:
A photographic printer includes a splice detector for detecting the presence of a splice in a photographic paper web. The splice detector is positioned upstream of the printing aperture of the printer, and provides a signal indicative of the presence of a paper splice prior to the time that the splice reaches the printing aperture. Following detection of the splice, the paper feed control of the printer advances the web a number of additional feeds sufficient to advance the splice past the printing aperture. As a result, recording of a photographic image on the portion of the print paper web containing the splice is avoided.
Abstract:
A photographic printer has a punch marking system for placing cut and end-of-order marks on the photographic paper. The punch marking mechanism is adjustable to accommodate different widths of print paper. The punch marking mechanism includes guide rods which are positioned transverse to the path of the print paper. First and second carriage assemblies are movable along the guide path defined by the guide rods on opposite sides of the center line of the paper path. A lead screw moves both the first and second carriage assemblies along the guide path in an essentially symmetrical manner about the center line of the paper path. Interchangeable inserts of different widths may be inserted between the carriages to define a spacing between the first and second carriages for a desired paper width. The punches or other marking devices are carried on the first and second carriage assemblies.
Abstract:
A pumping system comprises an internal combustion engine, a generator, a pumping unit and a heat recovery system. The generator is driven by the internal combustion engine. The pumping unit is powered by the generator. The heat recovery system thermally couples the internal combustion engine with the pumping unit.

Abstract:
A method for controlling the damping force of a damper containing a movable object in a magneto-rheological fluid, in which a positive magnetic field is applied to the fluid to achieve an increase in viscosity (and an increase in damping force) and the polarity of the magnetic field is reversed by negative electrical energy to remove residual magnetism before reestablishing the magnetic field at a lower level to achieve a predictable decrease in viscosity (and a decrease in damping force).

Disclosed are nucleic acid sequences encoding components of the dystrophin-glycoprotein complex. The components include dystroglycan, the 50 kDa protein component and the 59 kDa protein component. Also disclosed are compositions and methods which relate to the disclosed sequences.
Abstract:
An apparatus in combination with a photographic printer indicates the position of a selected film frame at a print gate aperture relative to other film frames in a disc-like film unit having a plurality of film frames. The apparatus includes a disc-like film unit holder for rotationally indexing selected film frames to the print gate aperture having a first gear. A second gear provides motive force through a suitable actuating mechanism for rotationally indexing the disc-like film unit on the holder assembly. A third gear having indicia for indicating relative positions of the film frames in the disc film unit is rotatably positioned between the first and the second gear and cooperates with the first and the second gear to rotationally index the disc-like film unit on the holder assembly. Only the indicia that indicates the selected film frame positioned at the print gate aperture is viewable.
Abstract:
A photographic printer has a punch marking module for placing cut and end-of-order marks on the photographic paper. A quick connect/disconnect mounting assembly automatically centers the punch marking module properly with respect to a paper mask. The quick mounting assembly includes a pair of detent bars and registration pins on a mounting base attached to the paper mask. A rigid member and a pair of plate holders form the bottom of the punch marking module. A plurality of ball plungers engage a plurality of recesses in the detent bars and the end plate holders engage side edges of the mounting base. The ball plungers apply a force to the rigid member holding it against the registration pins in an engaging relationship.
