Abstract: A method of nitrating resorcinol which is selective for the production of the 4,6-dinitro resorcinal isomer. A resorcinol-based starting material is admixed with a nitrating solution from which substantially all nitrogen dioxide and nitrous has been removed. The nitrating solution contains white fuming nitric acid, a nitrosonium ion control agent such as urea, and, optionally, concentrated sulfuric acid. The 4,6-dinitroresorcinal isomer is provided in yields of about 65-85% with minimal production of undesirable side products.

Abstract: An improved easy open can end having a retained tear strip (18) extending diametrically partly across the can end defined by a score line, and a graspable pull tab (10) adjacent and outside the open end of the score line. The pull tab is attached to the can end by means of a rivet (9), the can end around the base of the rivet being deformed so as to slightly tilt the rivet (9) toward the finger end of the pull tab (10). Accordingly, initial lifting of the pull tab is fully directed to the initial fracture of the score in line (16) immediate in front of the rivet, thereby ensuring desirable venting action of internal pressure and allowing opening of the can end with less effort.

Date Aug. 24, 1989.A variable length encoding method for encoding a finite or infinite series of values corresponding to a random variable whose distribution monotonically decreases on either side of the mean value in which the encoding tree has a regular structure which is defined by an arithmetic and logic device. In order to encode each value E, a first binary word, including only bits having a same value and whose number of bits B is an increasing function of the value to the encoded E, is determined. The number of bits B is computed according to a predetermined arithmetic and logic function B(E). The method also involves determining a second binary word having a value to be encoded, in the set of values to be encoded arranged in order of decreasing probability, and whose number of bits B' is derived from the function B(E) and from the number of bits B in the first binary word. A code word is formed by combining the first and second binary words thus determined.
