A photopolymerizable composition which contains one or more olefinically unsaturated compounds and from 0.2 to 20% by weight (based on the unsaturated compound(s)) of a photoinitiator, with or without conventional additives, the photoinitiator being a mixture of one or more aromatic carbonyl compounds of the general formula (A) ##STR1## where Ar is an ortho-arylene radical which may or may not be substituted by one or more radicals R.sup.1 to R.sup.4, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are id...

A catalyst comprising 10 to 30 wt.% of nickel as nickel oxide, 20 to 60 wt.% of calcium as calcium oxide, 10 to 70 wt.% of aluminum as aluminum oxide and containing less than 1 wt.% of silicon dioxide. The catalyst is prepared by using: as the starting material for the nickel component, fine particles of nickel oxide obtained by heating a nickel compound which is decomposed to nickel oxide by heating at a temperature in the range of 400.degree. to 800.degree. C in the presence of oxygen; as the ...

A folding paperboard carton including an interior divider is formed from a single-piece blank. The divider is attached to a flap or wall panel of the carton blank, and after the carton is glued in a folded mode, unfolding the carton to its set up mode releases the divider from its attachment to the flap or wall panel to form a divided carton.

A sling for moving loads is comprised of a coil having a multitude of substantially uniform, closed and juxtaposed loops. The loops are elongated to form a middle portion of two substantially parallel adjacent coil sections, and a pair of bight-shaped portions at opposite ends of the middle portion. Each coil section is comprised of a plurality of filamentary material strands which are spaced from each other. A plurality of windings are wound about strands in each of the coil sections so as to r...

Asphaltic compositions are provided comprising a major proportion of straight-run asphalt, and minor proportions of a refractory aromatic residual fraction (syntower bottoms), ethylene-vinyl acetate copolymer and terpenic resin.

Asphaltic compositions are provided comprising a major proportion of road asphalt, and minor proportions of thermal asphalt, ethylene-vinyl acetate copolymer and terpenic resin. A method for manufacturing such compositions is described involving dissolution of ethylene-vinyl acetate copolymer and terpenic resin in thermal asphalt and addition of the resulting solution to road asphalt.

This invention relates to transversely-excited gas lasers, in which the gas may be at atmospheric or greater pressure and in which the gas is excited by means of a distributed electric discharge between two electrodes. The electrodes, which are preferably elongate, are such that an initial trigger discharge occurs between minor trigger portions of the electrodes which conditions the discharge gap between the electrodes resulting in a distributed, preferably glow-type discharge, between the major...

5-Deazariboflavin, its phosphate ester and nontoxic salts thereof and its novel bis(loweralkoxymethylene) derivatives have antiprotozoal and antiparasitic activity. They are particularly useful for controlling cecal and/or intestinal coccidiosis when administered in minor quantities to animals, in particular to poultry, usually in admixture with animal sustenance. The compounds are included in compositions useful for the prevention and treatment of coccidiosis in poultry.

A method of operating a cycloconverter which is adapted for use with a load in the form of a parallel resonant circuit and for use with an intermediate d-c link supplied by an a-c voltage source and including a smoothing choke and a controlled rectifier, the cycloconverter including an inverter circuit comprising a bridge circuit having output terminals adapted to be connected to the load and input terminals adapted to be connected to the d-c link, in which starting of the cycloconverter is real...

A simulated granite and its preparation are provided. The granite comprises (A) about 35 to 95% by volume of a matrix consisting essentially of (1) at least 34% by volume of polymer, preferably predominantly an acrylic polymer, having a refractive index (n.sub.D) between 1.4 and 1.65 and (2) about 1 to 50% by volume of at least one microscopic filler having an amorphous or mean crystalline axial refractive index between 1.4 and 1.65, (B) about 0.1 to 50% by volume of macroscopic opaque particles...
