Abstract: The state of a photosensitive material processing solution is easily determined from values of multidimensional analysis by utilizing Mahalanobis distance. The Mahalanobis distance is calculated, and a determination is made as to whether or not the Mahalanobis distance is greater than or equal to a threshold value. If the Mahalanobis distance is less than the threshold value, the processing solution is determined to be normal, the Mahalanobis distance is displayed on a display unit, and a determination is made as to whether or not the number of sets m of normal values has become greater than or equal to a predetermined value m0. If m >/= m0, data of the characteristic values in the oldest set in a time series is deleted, and a set of data of newly detected characteristic values is added to calculate the Mahalanobis distance and update a database. If the Mahalanobis distance is greater than or equal to the predetermined value, a developing solution is determined to have become abnormal, the degree of abnormality is displayed, factors which caused the abnormality are determined, a corrective measure is determined on the basis of a combination pattern of factors, and the measure is displayed. <IMAGE>

Abstract: A method for reducing the abrasion of a silica-containing calcined kaolin pigment by the controlled leaching of silica from the pigment, preferably by the use of a caustic solution to dissolve the silica out of the calcined kaolin. In another aspect of the invention, the brightness, opacity, or both of a calcined kaolin is increased by increasing the fineness of the kaolin feed supplied to the calciner. The combination of these methods results in the production of a calcined kaolin with low abrasion and high brightness and opacity. Another aspect of the invention concerns an improved method of filtration of dilatent materials such as the leached calcined clay.

Abstract: An apparatus for ensuring proper engagement between connectors in external pneumatic compression devices. Two or more compression bladders are connected via tubing to a controller by a mated connector unit. Each mated connector includes an upstream portion and a downstream portion. The upstream portion includes a shut-off valve per individually addressed bladder. The downstream portion includes structure which defeats or opens the shut-off valve in the upstream connector and allows for fluid flow. Internally and externally, the mated connectors are configured for reciprocal engagement. Even if visual orientation of the connectors fails, the reciprocal structure of the connectors prevents incorrect engagement therebetween.

Abstract: This invention relates to a fluid dispersion of at least one dibenzylidene sorbitol acetal derivative. The sorbitol acetal derivative is useful as a clarifying agent for polyolefins and the inventive fluid dispersion permits improvements in the handling and processing of and mixing within the polyolefin composition. The inventive dispersion must be shelf stable, retain its nucleating effects, be compatible with polypropylene (and other polyolefins), and possess both short-term and long-term viscosities which permit acceptable transport through a standard polyolefin-manufacturing peristaltic pump. The preferred inventive dispersion thus comprises 3,4-DMDBS and at least one ethoxylated nonionic surfactant having an HLB of greater than about 8.5. Preferred surfactants include those selected from the group consisting essentially of ethoxylated sorbitan (C8-C22) monoesters and ethoxylated nonyl-phenol ethers. The inventive dispersion may be introduced within any polyolefin composition, preferably polypropylene, which may then be molded into any shape or form. A method of producing a polyolefin plastic utilizing the inventive dispersion is also provided.

Abstract: The device comprises two successive belt conveyors (26, 28) for transporting products (14) in a slat formation (S) along the first conveyor path (10). A release device (22) is mounted on the downstream end of the first belt conveyor (26), consisting of a deflection roller (36) for the conveyor belt (34) of the belt conveyor (26), a guide element (32) embodied as a roller (38) and a drive element (46). The upstream end (66) of a transfer conveyor (52) is coupled to the drive element (46). When the free end (64) is in return position and the guide element (32) is in idle position (30), the slat formation (S) is transported in a straight line along the first conveyor path (10). If a product (14) from the slat formation (S) is to be transferred to the second conveyor path (18), the guide element (32) is then placed in release position (30') and the end (64) is placed in the working position (66') by means of the drive element (46). As a result of the curvature thus produced in the active trunk (34'), the front edge (24) and the following edge area (24') of the product (14) to be fed to the second conveyor path (18) is raised and is introduced into the conveyor gap (54) of the second conveyor path (18).
