Abstract: AROMATIZED POLYACETYLENES     Abstract of the Disclosure Polyacetylenes, either homopolymers or copolymers, are rendered more soluble and/or more thermally stable with-out destroying their film-forming properties and with minimal decrease in their high carbon content by reacting them:with one or more 2,3,4,5-tetrasubstituted cyclopenta-diones commonly called tetracyclones.  These latter compounds, together with the acetylenic groups of the polymer, undergo a cyclization reaction to produce a 3,4,5,6-tetrasubstituted 1,2-phenylene moiety in the polymer backbone.  Because of their high thermal stability these polymers are especially useful as binders for graphite fibers in making grap hite composites or to produce films or coatings for high temperature applications.

Abstract: Abstract of Disclosure Monomeric esters of polyalkylene glycols and .alpha.,.beta.-un-saturated carboxylic acids are prepared, using a polyalkylene glycol or mono-ether derivative of an alkylene glycol or poly-alkylene glycol which has a tendency to form peroxides, by heating a mixture of the glycol or derivative, a hydrocarbon solvent, and a small amount of a dilute caustic or sodium borohydride for a time and to a temperature sufficient to decompose the peroxide, and then reacting the glycol or derivative with an unsaturated acid such as acrylic acid or methacrylic acid in an inert atmosphere and in the presence of a suitable esterification catalyst and polymerization inhibitor. The crude reaction product is purified by extraction with an aqueous base, such as sodium carbonate, to remove acidic impurities and is thereafter treated with fuller's earth and decolorizing charcoal to remove any color bodies still present. The decolorizing agents are then removed by filtration.

Abstract: ABSTRACT OF THE DISCLOSURE      Pneumatic tires with colored sidewalls are produced by applying one or more elastomeric coatings thereto.           A colored polyurethane elastomeric coating may be applied directly to the sidewall, but it may be applied to a primer elastomeric coating which is first applied and the colored coating is applied to it either before or after it is cure.  Usually, the elastomeric coatings are applied over a barrier strip that is in the rubber sidewall to prevent stabilizer or other discoloring agent from bleeding from the sidewall and discoloring the primer coating or the colored coating or both.           Barrier strips are well known in the art.  They are cured into the rubber during the cure of the tire.           The color of the colored coating may be produced by dyeing or pigmenting.           The one or more coatings which are applied in pro-ducing the colored sidewall are sufficiently flexible to with-stand the flexing of the sidewall of the tire during prolonged use without cracking and must be firmly bonded to the sidewall and to one another so as not to separate during such prolonged flexing.  Furthermore, the colored coating must resist deteriora-tion by environmental conditions such as ozone, oxygen, sunlight, etc.

Abstract: ABSTRACT OF THE DISCLOSURE             A specific type of protein, which has been designated B-protein (Bucovaz-protein), is present in most serum of indivi-duals with cancer. The B-protein interacts with a low molecular weight protein component, which is released by the coenzyme A-synthesizing protein complex (Coa-SPC) of Bakers' yeast during the course of CoA synthesis. This low molecular weight protein, for purposes of identification, is referred to as binding protein. The binding protein has a molecular weight of 10,000 to 15,000. Interaction of radioactively labeled binding protein of CoA-SPC with the B-protein of serum provides a marker for the detection of cancer. Of 3005 serums assayed, which included 908 patients diagnosed as having cancer, the B-protein assay agreed with the clinical diagnosis in more than 89% of the cases.

Abstract: ABSTRACT OF THE DISCLOSURE           A method for the initiation of a number of electric detonators by means of a blasting machine of the type in which a capacitor is charged, in which level-sensing units measure the level of the charge, and where the detonators are initiated by the electric energy stored in the capacitor being supplied to the detonators, either by means of automatic firing at the in-tended charge level or through manual firing after indication that the intended charge level has been attained.  According to the method, the charge level of the capacitor in connection with firing is in a limited range which follows the variations of the load between different initiation occasions in such a way, that the current impulse provided to each detonator assumes a value between a minimum and a maximum limit, and where the limits for each individual case of load within the operating range of the apparatus are adapted to suit the electrical and other physical characteristics of the detonators, so that safe initiation and a disturbance-free firing process are obtained.

Abstract: Abstract of the Disclosure Negative resist compositions are based on carbonaceous polymers with substituent branches containing epoxy groupings.  Inclusion of halogenated aryl groundings in the polymers results in stabilization with respect to ionizing radiation used for dry processing following lithographic development--e.g., ion milling.  Halogenation is responsible for retention of sensitivity to deli?eating radiation--e.g., e-beam, e-flood, X-ray.  Lithographic qualities are such that exemplary members are promising for large-scale integration direct processing.
