Abstract: An apparatus and method for enlarging digital photographs in a dark room environment by interchanging the film carrier with a digital projection module, wirelessly receiving the digital photograph data within the digital projection module and then automatically and wirelessly configuring the enlarger to generate the enlarged photograph on photosensitive printing paper. The apparatus and method include a software application for use on a computing device containing the digital photographs that permits the user to wirelessly communicate with the enlarger to configure and control the enlarger for printing. The digital projection module permits the enlarger to be easily reconfigured for enlarging photographs produced from film. An alternative is also disclosed that uses a laser projector instead of the interchangeable digital projection module for generating enlarged prints from digital photographs. The software application also permits burn and dodge effects in the print.

Abstract: A shrink-wrap packaging system comprising a supply of shrink-wrap film, a sealer system and an oven. The sealer system includes a hot-knife assembly, which encapsulates items being packaged by cutting, joining and sealing layers of shrink-wrap film that an operator fits around the items. The hot knife includes a double-edged blade having an electrical surface heater element fixed thereto. The heater element comprises a first layer of electrical insulation fixed directly to the blade, a serpentine resistive film deposited on the first layer and a second layer of insulation covering the resistive film. The oven includes a tunnel in which the encapsulated items are heated to form a shrink-wrap package. The oven includes heat exchangers that mount adjacent the tunnel. The heat exchangers generate heat via an array of electrical surface heater elements similar to those mounted on the hot knife.

Abstract: A negative carrier for use with photographic enlargers consists of two main sections, an upper mounting plate and a lower mounting plate interlocked together to secure and flatten the perimeter of a negative film strip during enlarging when the strip is in registration with aligned central rectangular apertures formed in each plate. Fixed pins located symmetrically about the central aperture on the upper surface of the lower plate have shaft and head portions to establish and maintain alignment of the inserted negative film strip with respect to the central aperture of the lower plate so that frames of the negative film strip may be slid into registration with the central aperture. The upper surface of the upper mounting plate is provided with protruding tabs for holding mounted slides and flexible filter sheets in alignment with the central aperture.

Abstract: Disclosed is a soft camera case of the "ever-ready" type, in which the case is suspended by a carrying strap, in such a position as to provide swift and easy access to a camera, as for example when one observes a photographic subject and must take a photograph with minimum delay, lest the opportunity be lost. The case is so shaped as to be universally adapted to receive cameras of different makes and sizes, while yet protectively, snugly enclosing the same. A carrying strap has its ends connected directly to the camera, and has end portions loosely slidable in apertures provided in the cover of the case. Upon removal of the camera, the case is free to slide along the end portions of the strap until its cover engages shoulders provided upon the strap to limit further slidable movement. The end portions are adjustable in length, so that the case and camera will separate only to the extent desired by the particular user.

Abstract: A contrast control device fogs a photographic recording medium with diffuse light simultaneously with the imaging of that medium. The diffuse light is colinear with the imaging light. The contrast control includes a semi-transparent mirror arranged diagonally across the light path. A fiber optic cable collects diffuse light and delivers it at a right angle to the cone of imaging light. This diffuse light also passes through the partial mirror and is received by a reflector. The reflector converts the diffuse light into a diffuse cone of light which approximates the imaging cone of light. This second or diffuse cone of light is reflected onto the partial mirror which in turn, reflects it onto the photographic medium substantially colinear with the imaging cone of light.

Abstract: A digital color printer system measures and provides a digital display for the primary color values of incident light from a colorhead for the system. The color mixture of light from the colorhead can be programmed in accordance with selected color values for the accurate reproduction of a print from a negative. The color printer system includes a microprocessor for carrying out various program functions for calculating, utilizing, and storing color value and exposure data, and a combined accessory unit including a keyboard, a input/output device, and a color analyzer probe interfaced with the microprocessor.

Abstract: A photographic processing drum includes a trough coaxially arranged within and spaced apart from the interior surface of the drum. A cap sealingly fitted to one end of the drum includes separate channels, isolated from each other, for conducting fluids into and out of the drum. Fluids introduced into the inlet channel are emptied directly into the trough without first contacting the interior surface of the drum. A method for employing the photographic drum in the processing of light-sensitive emulsions is also discussed.
