Abstract: An aqueous coating composition comprises (a) a hydrophilic binder; (b) an ester of cellulose having at least 8 acyl groups per C24 cellulose unit wherein at least a majority of the acyl groups are derived from an aliphatic polycarboxylic acid having from 3 to 6 carbon atoms; or a salt of the ester; and optionally (c) a hardening agent in an amount sufficient to render the composition water-insoluble after coating and drying of the composition. The cellulose used in preparing the ester is preferably a deacetylated cellulose acetate prepared by reacting cellulose acetate with an alkali metal alkoxide dissolved in the corresponding alcohol, e.g. sodium methoxide in methanol. The coating composition is useful for forming water-insoluble, conductive and highly-adherent layers in composite bases or elements, and particularly in photographic elements having hydrophobic supports. The conductive layers can be used, for example, as conductive subbing layers or conductive pelloid layers. Salts of cellulose esters that are derived from cellulose prepared as described above, have a lower solution viscosity, and therefore have improved coatability. They are also more conductive than similar salts prepared from cellulose made by deacetylating cellulose acetate with aqueous ammonia.

Abstract: The present invention is directed to a lens with an optical element (20) formed of a radiant energy transmitting material with a graded index of refraction having a predetermined profile which extends radially from a longitudinal axis (23) of the lens (20). A first surface (24) and an opposing second surface (26) of the optical element (20) extend radially outwards from the longitudinal axis (23) of the lens (20), and one of the first and second surfaces (24, 26) is aspherical. This optical element (20) can be combined coaxially with a second optical element to form a doublet lens. The second optical element is formed of a radiant energy transmitting material with or without a graded index, and when the graded index is included the second element has a gradient profile which is an inverse of the gradient profile of the first optical element (20). The second element has a first predetermined shaped surface arranged for rays of radiant energy from a remote source to be incident thereon, and an opposing second predetermined shaped surface. Each of the first and second surfaces extend radially outwards from a longitudinal axis of the lens.

Abstract: Apparatus (10) for measuring lateral charge distribution on a moving web (16) includes a cylindrical roller (12) having at least a pair of charge measuring segments (14a, 14b) on the cylinder surface which are electrically isolated from each other and aligned end-to-end in the direction of the axis of rotation (13a) of the cylinder. Each of the measurement segments (14a, 14b) is adapted to be connected to a separate electrometer (50, 51). The cylinder is mounted on means (30) to move the cylinder in a direction perpendicular to the longitudinal direction of conveyance of the web over the surface of the cylinder. Means (40) for measuring lateral displacement of the cylinder is used for calculation of the proportion of web area in contact with one segment relative to the total web area in contact with both segments. The proportionate measured charge represents the integral charge on a fraction of the web and by taking periodic measurements as the cylinder is moved laterally across the web, a profile of lateral integral charge distribution is determined. The corresponding profile of lateral charge density distribution is then readily determined by differentiation of the charge distribution profile curve.

Abstract: A solid state motion analysis system (10) stores images of an event (14) at a fast frame rate and plays back the images at a slower frame rate to facilitate analysis of the event. The motion analysis system includes a solid state imager (12) which is selectively operable at different frame rates and further includes a solid state memory (32) for storing a plurality of image frames. A video enhancement/trigger circuit (46) includes a comparison circuit (48) to compare selected images produced by the imager (12) to determine a change in the value of an image characteristic between the images. When a change is determined, the video enhancement circuit (46) enhances the region of the image which changes and may also produce a trigger signal to alter the mode of operation of the motion analysis system (10). Thus, storage of image frames may be started or stopped when a difference in luminance or color occurs between successive image frames, such difference indicating a change in the event. Video enhancement includes enhanced grey scale and pseudo color enhancement.

Abstract: When using unstable processing solutions, high recirculation and/or replenishment rates may be required. However, when replenisher is added to a processing tank, a noticeable drop in the temperature of the processing solution may occur. Such a drop in temperature may lead to variable photographic sensitometry of the material being processed. Described herein is apparatus in which temperature control means (28) are provided to ensure that the temperature of the solution being added to the processing tank does not produce such a temperature drop.

Abstract: A digital imagery capture and storage mechanism controls the operation of a high resolution digital film scanner (12) such that the scanner scans the image twice, the first scan being used to gather data to calibrate the scanner (12), and the second scan being used to capture and store a high resolution image. The scanner carries out a low resolution mode, prescan of the color photographic image frame, thereby obtaining a low spatial resolution digitized image. This low resolution digitized image is then analyzed by a scene balance mechanism (14) to determine how the response characteristic of the scanner's imaging pixel array sees the image and encodes its spatial content. The output of this analysis, which represents the color balance content of the digitized image, is used to adjust the sensitivity range of the scanner, so that, during a subsequent high resolution scan of the image, the essential subject matter of the image will fall within the linear portion of the response range of the scanner's imaging pixel array. The high resolution digitized image is then processed by the scene balance mechanism (14) to map the image data into adigitized image having a reduced encoding resolution corresponding to that of an attendant framestore.
