Abstract: A fibril aggregate that includes a multiplicity of carbon fibrils whose longitudinal axes have substantially the same relative orientation, each of the fibrils characterized as having graphitic layers that are substantially parallel to its longitudinal axis and being free of a continuous thermal carbon overcoat, and a method of preparing such aggregates.

Abstract: Compounds of the formula I or salts thereof ##STR1## where R.sup.1 is H or an aliphatic radical; R.sup.2 and R.sup.3 are H, alkyl or phenyl; W is O, S, NR.sup.4 or NOR.sup.4 ; X is CHR.sup.2, O or NR.sup.4 ; L is a (substituted) phenyl, naphthyl or monocyclic heteroaryl radical, A is a (substituted) pyrimidyl, triazinyl, triazolyl or bicyclic heteroaryl radical, and m and n are 0 or 1, have advantageously herbicidal or plant growth-regulating properties.

Abstract: Compounds of the formula ##STR1## exhibit, in the pre-emergence process and in the post-emergence process, a good herbicidal action against a number of dicotyledonous weeds, they are well tolerated in monocotyledonous crops, such as wheat, barley, rice, sorghum and maize, and are also selectively active in some dicotyledonous crops such as soy beans, groundnuts and the like.

Abstract: An improved shoring frame adapted by a unique design to utilize relatively thin-walled aluminum tubing with a reasonable load-rating, be easily manufactured, and be compatible with existing steel accessories; where the extruded aluminum legs are each generally circular with a longitudinally-extending flattened portion for attaching struts and studs, and preferably having at least two internal ribs, circumferentially symmetrically-spaced relative to said flattened portion axially to contain accessories such as existing jack screws, extension legs, U-head fixtures, and the like.

Abstract: Aromatic amines are obtained in high yield and purity by treating the corresponding cyclohex-2-en-1-on-oxime hydrochlorides with the at least threefold molar amount of acetic anhydride.

Abstract: Compositions containing a polymer or copolymer of acrylonitrile stabilized against thermal discoloration by the presence, in the composition, of a nitroalkane, a nitrocycloalkane, an alkyl-, cycloalkyl-, or aryl-isocyanate, or of a pyrocarbonic acid dialkyl ester are disclosed together with methods for making such compositions.

Abstract: A method for dimerizing heptadiene acid esters in the presence of a catalyst which is a metal of Group IA of the Periodic System or an alcoholate, hydride, amide, or tritylate thereof, or is an alcoholate, hydride, or amide of a metal of Group IIA of the Periodic System.
