Abstract: The output end of a very high speed continuous motion cylindrical can decorator is provided with unloading apparatus in the form of a continuously moving closed loop suction belt supplied by first and second continuously rotating, parallel axis, suction applying conveyor wheels. Cans held on the second wheel are on two concentric circular tracks and are transferred by suction to the belt. The first wheel carries cans along a single row circular path. In a region where the first and second wheels overlap partially, alternate cans on the path are delivered to one track of the second wheel and the remaining alternate cans on the path are delivered to the other track of the second wheel. Alternate cans supported on the first wheel may be moved radially so that the cans on the first wheel are in two rows which intersect the two tracks on the second wheel at respective common tangents of each row and the respective track.

Abstract: To minimize the presence of roll-to-roll nips in an inking system for a printing plate cylinder, an ink transfer belt transfers ink from an ink transfer roller, which receives ink from a supply, to the ink receiving elements on a printing plate cylinder. A plurality of guide rolls inside the loop of the ink transfer belt contact the drivable surface of that belt. A drive is connected with one of the guide rollers for driving it to rotate at a first velocity, which is the velocity of the ink transfer roll and of the printing plate cylinder. An ink distribution roller is disposed outside the loop of the belt in contact with the opposite, ink transfer surface of the belt and between the ink transfer roller and the printing plate cylinder. The ink distribution roller is driven to rotate at a different speed than the ink transfer belt and is also driven to vibrate or to oscillate axially for ink distribution on the ink transfer surface of the belt.

Abstract: An image of a symbol or other indicium of origin or authenticity is encrypted, and printed on the item or a label in superposition with a color mask. In a preferred embodiment, an intermediate parallax record is formed of a series of images of a symbol or other indicium, each differing from the preceding one by a predetermined amount of parallax (i.e. change of viewing angle.) A multiple exposure of the series of intermediate parallax record images is made through a lenticular screen to create the encrypted image of the indicium. The lenticular screen and the medium on which the multiple exposure is made are moved relative to each other between exposures. The encrypted image and the superimposed color mask are then printed as a composite image to produce an unintelligible criss-cross of colored lines. When viewed through a lenticular screen which matches that used to create the encrypted image, the original indicium is revealed in clear form.

Abstract: An improved process for separating high purity alkyl glyoxylate from complex mixtures containing alkyl glyoxylate, alkyl glycolate, water, alcohol and miscellaneous impurities by an azeotropic distillation operation using an azeotroping agent selected from the group consisting of methylene dichloride, 1,1,1--trichloroethane, and benzene.

Abstract: Compositions and processes for activating metal surfaces prior to coating with a phosphate compound are disclosed. Colloidal alkyl benzene sulfonate salts are disclosed as a novel class of activating materials to replace titanium containing Jernstedt salt baths for treatment of metal surfaces prior to coating with a protective phosphate material.

Abstract: A composition of matter in particulate, crystalline form. The composition comprises a hydrate-forming phosphate selected from the group consisting of sodium tripolyphosphate, sodium pyrophosphate and trisodium phosphate, between about 0.1% by weight and about 23% by weight added water in the form of water of hydration said water containing in solution sufficient surfactant to provide the composition from about 0.20 ppm and about 125 ppm of a surfactant. Methods for preparing such compositions are also disclosed.

Abstract: Granular or powder compositions containing diethylenetriaminepenta(methylenephosphonic acid) and/or its salts in admixture with sodium sulphate and/or bisulphate in an amount, expressed as the equivalent amount of anhydrous sodium sulphate, of at least 60% of the dry weight of the diethylenetriaminepenta(methylenephosphonic acid) and/or its salts can be stored for extended periods while remaining in the form of free-flowing solids.

Abstract: The invention is directed to a seal assembly for sealing an electrode movable vertically through an opening in the roof of an electrode furnace. The seal assembly comprises a lower assembly including an annular base adapted for sealing engagement with the roof around the roof opening, an annular wall extending up from the base, and an annular scraper extending generally radially inwardly relative to the wall and having an inner edge adapted for scraping material from the outer surface of the electrode as the electrode moves vertically. The seal assembly also includes an upper assembly comprising a pair of annular seals of refractory material disposed in vertically spaced relation, each seal comprising a plurality of discrete arcuate seal segments, a mechanism for applying an inward radial pressure to each seal to hold it in sealing engagement with the electrode, and a mechanism for holding each seal against upward movement relative to the roof as the electrode moves up through the roof opening.

Abstract: There are disclosed novel, highly stable sulfone peroxycarboxylic acids useful in detergent compositions alone or as bleaching agents which are represented by the formula ##STR1## wherein A and B are organic moieties bonded to the sulfur atom by a carbon atom and at least one of A and B containing at least one ##STR2## group bonded to a carbon atom.

Abstract: A continuous process for preparing nitrilotriacetonitrile in which the reactants, formaldehyde, hydrogen cyanide, and either ammonia or hexamethylenetetramine are reacted first in a mixing reactor, preferably a circulating loop reactor at from about 90.degree. C. to about 120.degree. C., then reacted in a plug flow tubular reactor at from about 95.degree. C. to about 120.degree. C., then after cooling the reaction mixture crystalline nitrilotriacetonitrile is recovered.

Abstract: The disclosed process is employed to recover phenol from aqueous solutions produced by distillation of the product of a process for producing a phenyl ester by the reaction of a carboxylic acid and phenol. Purified phenyl ester is employed to extract phenol from the aqueous solution. The extract is combined with raw product for recovery of the phenol and phenyl ester. In a preferred embodiment the process for producing the phenyl ester is continuous and the extract containing phenol and phenyl ester are fed to the dewatered ester stream for product recovery.

Abstract: An electrolytic filter capacitor of wound elongate electrode foils and an electrolyte in a separator between the foils has very low effective series resistance and inductance by virtue of particular terminal connections to the foils. A pair of wires extend across and are joined to the foils, respectively, at corresponding locations along the wound elongated foils; the ends of the wires extend oppositely to provide four terminals for the two foils, an oppositely poled pair of terminals at each end of the capacitor.

Abstract: In a distribution circuit for connecting a load to an a-c source, it is known that a ground-to-neutral short tends to reduce the sensitivity of ground fault detectors that use a differential current transformer to sense line-to-ground leakage. A resonated coil on a core links the neutral conductor forming part of a protective device for interrupting the load circuit in the event of reduced Q of the resonated coil caused by a neutral-to-ground fault. The core must also link the line conductor, for otherwise a loop including the line, the load and the neutral would wrongly have a like effect.The same core and coil are used with a common amplifier for the neutral-to-ground fault detector and for the line-to-ground leakage detector, so that the apparatus can be economical and compact. Furthermore, so long as there is no neutral-to-ground fault, the amplifier delivers a signal of normal strength that monitors the integrity of both detectors.
