A photographic element is disclosed comprised of a support and, coated on the support, at least one radiation-sensitive silver halide emulsion comprised of tabular silver halide grains and a dispersing medium. The emulsion includes as a vehicle methacrylate polymer latex capable of reducing pressure sensitivity h...
The image transfer properties and other pro­ perties of an electrostatographic toner composition are improved by blending the binder resin of the toner with a multiphase polyorganosiloxane block or graft condensation copolymer which provides polyorganosiloxane domains at the toner particle surfaces.....
Apparatus and methods are provided for separating photographic film strips (12,14), adhered to a splice (18), by restricting movement of the splice (10) and then pulling the film strips longitudinally in opposite directions. According to one feature, the splice adhesive (28) is heated until it softens, preferably with ...
Process is disclosed for the selective mono-­epoxidation of styrene, styrene analogs, and styrene derivatives. Such compounds are contacted with an oxygen-containing gas in the presence of a promoted, optionally supported silver catalyst under defined reaction conditions, thereby selectively producing epoxides in good...
A thermal print element comprising a support having thereon a layer containing a thermally-­transferred dye image, the element having at least one layer of adhesive thereon comprising a linear, random copolyester of one or more aromatic dibasic acids and one or more aliphatic diols, modified with up to 30 mole % of on...
Photographic elements are disclosed having a first coupler represented by the formula: COUP₁-T-INH wherein COUP₁ is a coupler moiety, T is a timing group bonded to INH through a substituted or unsubstituted methylene group contained in T and bonded to COUP₁ through an O, S, or N atom contained in T, ...
A photographic camera (201) is intended for use with a film cassette (1) having a film-exposure status indicator (77) movable from an unexposed position for providing a visible indication that a filmstrip (F) within the cassette is generally unexposed, to a partly exposed position for providing a visible indication tha...
A web spooling system has a chuck (22) that is coupled to a spool for rotating the spool (14) to wind a length of web material (12) onto the spool. Torque is transmitted from a drive shaft (32) to the chuck through a spring (34) coupled to the shaft and the chuck. A transducer (36) measures the angular relationship bet...
A multispot autofocus system, usable with a camera, includes a radiation emitter (32) for emitting visible or infrared radiation. The radiation is divided into at least three discreet beams (36a,b,c) of radiation by one or more holographic and/or diffractive optical elements (42). The beams of radiation are directed to...
Photographic elements having art oxidized developer scavenger that is a solid particle dispersion of a hydroquinone derivative. The solid particle dispersion of the oxidized developer scavenger offers improved stability to oxidation compared to conventional dispersions of hydroquinone derivatives....
A spool (30) for photographic film has a generally cylindrical core (40) with flanges (44) at the end portions of the core. A slot (50) through the core receives an end portion (34) of the film that is to be wound onto the spool. Hooks (60, 62) in the slot are engaged with the film through apertures (36) in the film fo...
Photographic elements containing a silver halide emulsion layer and an associated dye-forming coupler and stabilised with certain organic aryl disulfides incorporated therein or applied during processing. The compounds are preferably employed in the magenta layer to protect the magenta dye from fading by light....
A dye-donor element for thermal dye transfer comprising a support having on one side thereof a dye layer and on the other side a slipping layer comprising an organic lubricating material in a binder, the lubricating material comprising a nonhomogenous layer of a particulate ester wax comprising an ester of a fatty acid...
The present invention performs an interpolation operation between a pair of stereo images to produce plural intermediate images. The interpiolation operation involves estimating the velocity vector field of the intermediate images. The estimation for a particular intermediate image includes constraining the search for ...
A recording element having at least one layer comprising a crosslinked polymer having polymeric backbone moieties and crosslinking moieties, the polymeric backbone moieties containing tertiary nitrogen atoms, the crosslinking moieties connecting polymeric backbone moieties at the teritary nitrogen atoms by conversion o...
The present invention minimizes the effects of capillary and inertial forces on the film profile for a slide hopper, thereby making the film profile smooth and predictable even when the transition section is short. The invention enables improved coating uniformity over the main width of the coating and particularly at ...
A camera including a combined shutter and adjustable aperture is characterized by resilient means for uniformly dampening oscillations during operation. The combined shutter and aperture includes a stepper motor that drives a plurality of blades between a closed aperture blocking position and a plurality of open apertu...
A slide changing apparatus (10) is disclosed for use in a projection apparatus wherein photographic slides (12) can be projected onto a screen or viewed on a video monitor. The slide changing mechanism (10) includes a lever (16) having a displaceable part (26) which engages a slide (12) and transfers the photographic s...
