Abstract: ABSTRACT OF THE DISCLOSURE        Photopolymerizable compositions are described containing a polymerizable ethylenically unsaturated monomer, a photoinitiator or initiator system, and selected acidic polymeric binders.  The organic binder mixture contains a compound chosen from each of two selected classes.  These photopolymerizable compositions yield superior processability, i.e., on developing and stripping, in solely aqueous alkaline media devoid of organic solvents, decreased softness and/or tackiness, and improved adhesion when compared to the prior art.  The compositions are particularly useful for preparing photo-resists.

Abstract: Abstract of the Disclosure This invention relates to a process for effectively and completely reforming into a useful hydrocarbon oil(such as naphtha, kerosene and gas oil with high cracking rate) tar-sand bitumen and vacuum residues from various petroleum origins, which are difficult to treat in comparison with ordinary crude oil and which contain large amounts of asphaltenes and resins.          The process of this invention is a combined process of thermal cracking and hydrocracking.  The present invention is useful for the manufacture of pollution-free product oil from tar-sand bitumen and vacuum residues from various petroleum origins with a high desulfurization percentage of more than 90%.  The product oil can be used as a superior fuel oil having low sulfur and metal contents, and also as the starting material for secondary processing.

Abstract: AIR-DRYING COATING COMPOSITIONS   ABSTRACT OF THE DISCLOSURE      Air-drying unsaturated coating compositions are obtained by reacting at least 60% of the epoxide groups of a poly-epoxide with more than one epoxide group per molecule a) with 0.01 to 0.5 NH-equivalents, based on one epoxide group of ammonia, an aliphatic or cycloaliphatic primary or secondary amine and subsequently b) with 0.99 to 0,5 carboxyl equivalents, based on one epoxide group of acrylic or methacrylic acid, The reaction products may be mixed with solvents and/or copolymerizable monomers and are preferably hardened in the presence of known photoinitiators with the aid of energy radiation, and are thus useful as coating compositions for various substrates.    Their particular advantages are their stability in the dark and that they also harden very quickly in the presence of atmospheric oxygen.     Preferred substrates are paper and cardboards.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to a method and apparatus of recovering by-product fines, such as coal fines, by-product fines created in the manufacture and processing of metals or any very finely divided substance which may be of value when recovered to a usable form and which may be naturally found in the form of a silt or as the result of the manufacturing process, from a slurry or sludge thereof.  The slurry mass is firs-t treated to dissociate it into discreet units, if required, for further treatment to recover the fines contained within the discreet units of the slurry in the form of a usable end product.  The discreet units of the dissociated slurry are conveyed through a rotary-driven impeller feed conveyor and simultaneously a hot gas such as air or superheated steam if flowed through the conveyor in contact with the slurry segments ox discreet units.  This combined action of the rotary impeller feed and the flow of hot air uniformly breaks up and dries the discreet slurry units into particles of desired moisture content.  These particles may be beneficially utilized in this form or they may be further subjected to treatment to obtain a usable end product in a larger agglomerate form of desired moisture content for ease of handling the end product, depending upon the required application.  If further treatment is to be carried out, these particles are extruded en masse into larger agglomerates.  The extruded agglomerates are then broken off or cut in desired lengths which may or may not require additional drying depending upon the application of the product.  If additional drying is required, the present invention teaches the use of a second rotary-driven impeller 1.   feed conveyor in which the extruded agglomerates are conveyed while again simultaneously flowing a hot gas through this second conveyor in contact with the agglomerate to break up or size and further dry the agglomerates to a desired degree.  The final moisture content of the product exiting either the first or second conveyor may be accurately controlled by regulating at least one of the controls consisting of the rotary drive speed of the conveyor, the hot gas temperature, and the flow rate of the hot gas through the conveyor.  The rotary impeller of the conveyors is in the form of a ribbon screw throughout its length.

Abstract: ABSTRACT OF THE DISCLOSURE         An arrangement to eliminate the initial current overshoot which normally occurs when a tungsten incandescent lamp is connected to a power source.  The arrangement uses a negative temperature coefficient thermistor having a certain predetermined mass.  It has been determined that a practical limiter to eliminate current overshoot can be made only when the mass of the limiter is within a relatively narrow range.          The hot and cold resistance of the limiter must also be within prescribed ranges to give a limiter which is not only effective in eliminating the current overshoot, but also efficient in steady state operation such that the limiter dissipates less than 1% of the total power.
