Title: Method of selectively controlling plant growth
Inventor: OTTO SCHERER
IPC: C07D213/80
Filed: 1958-12-26
Abstract: The invention comprises esters of the general formula <FORM:0909372/IV (b)/1> wherein R represents an alkyl or alkenyl group containing 1 to 3 carbon atoms. These esters have herbicidal activity (see Group VI). The esters are produced by reacting the appropriate carboxylic halide or anhydride with 4,6-dinitro-2-sec. butylphenol, or with a metal salt of this phenol. In Example 1, the propionate of dinitro-sec. butylphenol is prepared by heating together dinitro-sec.-butylphenol and propionic anhydride, in the presence of a small proportion of pyridine, for 5 hours at 140 DEG -150 DEG C. The n-butyric and acrylic esters may be prepared in an analogous manner.ALSO:Herbicidal compositions comprise an ester of 4,6-dinitro-2-sec.-butylphenol having the general formula <FORM:0909372/VI/1> in which R represents an alkyl or alkenyl group containing 1 to 3 carbon atoms, in admixture with a solid or liquid diluent. In Example 3, a powder comprising 30 parts of acetyl-4,6-dinitro-sec.-butylphenol, 30 parts of sulphite waste liquor, 39.5 parts of kaolin and 0.5 part of sodium dodecyl-phenyl sulphonate was suspended in water, and the liquor was sprayed on an oatfield infested with charlock. The charlock was killed, but the oats were unaffected. Example 6 relates to tests with the acetic, propionic, n-butyric and acrylic esters of 2,4-dinitro-2-sec.-butylphenol in the form of emulsion concentrates in methanol.

Title: Improvements relating to the production of charge pellets containing metal oxides
IPC: C22B1/242
Filed: 1961-09-02
Abstract: Charge pellets containing metallic oxide and carbonaceous reducing agent, for use in smelting metals, are produced by mixing the oxide with an hydraulic binder, e.g. Portland or alumina p cement such as made from basic furnace slag, and a bituminous binder, such as crude baking coal preferably ground to powder so that at least 50% of the grains pass a 200 Tyler mesh and containing 1-3% pitch, forming the mixture into pellets with water, and allowing to harden without heating. The cement may comprise 3-10% of the mixture. The pellets may be subsequently preheated and prereduced at 500-1000 DEG C., e.g. in one or more shaft furnaces or a rotary kiln, to coke the bituminous binder.

Title: Composite electrode structure for magnetohydrodynamic device
IPC: H02K44/10
Filed: 1965-03-22
Abstract: The electrode for an MHD generator comprises an assembly of refractory oxide (zirconia or thoria) segments joined together by a joint formed of a noble metal or alloy (Pt, In, Pt-Rh or Ir-Rh alloys) or inert refractory metal (Nb, Ta, Mo, W). The segments are first coated on their adjacent faces with a dispersion of the selected joint material in a solvent and baked at 850 C. to ensure adhesion of the metal particles to the faces of the segments. After assembling together the assembly is again baked, in a reducing atmosphere for the noble metals or an inert atmosphere for the inert refractory metals, to provide the required bond. In an alternative method a thin metal foil may be placed between the uncoated segments and a bond obtained after a single baking process.
