Abstract: A process for the production of a black iron oxide pigment from Fe2O3 hematite iron oxide which may be an impure oxide produced by the “Ruthner” process or by other means, or which may be a mineral hematite. The process may be used to upgrade poor quality synthetic or natural hematite, or to improve their performance as red pigments, by conversion to black pigment with subsequent oxidation of the magnetite so produced back to hematite. The process uses a low temperature aqueous slurry reaction in which the hematite is contacted with a soluble source of Fe(II) ions in the presence of a soluble source of Fe(III) ions in an aqueous alkaline medium to convert the same to Fe3O4.

Abstract: The throwing arm for a clay target launching machine is designed with an adjustable leading edge or target-engaging edge of the throwing arm. This edge is separately, pivotally mounted on a main body member, which in turn is pivoted to launch the targets. By adjusting the angle of the leading edge of the throwing arm, causing it to be offset from a center line through the central pivot of the main body member of the throwing arm, the angle between two simultaneously released targets can be varied from an angle which is less than that of conventional devices to an angle which is greater than that of conventional devices. A further enhancement includes constructing the leading edge of the throwing arm with materials of different coefficients of friction to provide additional variations in the angle at which targets are released by the machine in which the throwing arm is used.

Abstract: Disclosed is a manually-operated garlic grater which is very easy to use and very efficient to grate cloves of garlic. This garlic grater has a casing defining a tubular cavity having a lateral opening. A handle is removably mounted in a rotatable manner onto the casing on top of one end of the tubular cavity. A hollow grating drum is rigidly connected to the handle so as to be rotated therewith. This drum extends within the tubular cavity when the handle is mounted onto the casing and has a cylindrical wall which extends at a short distance away from the inner wall of the tubular cavity. The handle and hollow grating drum altogether form one piece. A base is removably mounted onto the casing on top of the other ends of the tubular cavity. A wiper is rigidly connected to the base. This wiper extending radially within the drum when the base is mounted on the casing and bearing against the cylindrical wall of the drum to wipe the cylindrical wall when the drum is rotated.

Abstract: A composition comprising a terpene, an emulsifier, and a copper complex is provided, along with methods for its use as an algaecide. The composition is effective when used as an algaecide to treat algae growth in aquatic environments, even though it contains much less terpene than other commonly-used algaecides and can be used without a conventional surfactant. The composition is also less toxic and less flammable than other commonly-used algaecides.

Abstract: A process for preparing a vinyl isothiocyanate comprises contacting a halogen-substituted allyl thiocyanate, in solution and at an elevated temperature, with an acidic material which is either an acid or a halide or oxyhalide of an inorganic acid. The halogen-substituted allyl thiocyanate may be prepared from a dihalogenated alkene. The vinyl isothiocyanate may subsequently be converted to a thiazole.

Abstract: A target or rabbit launcher apparatus for firearm shooting exercise comprises a motor (2), a reducer (3) which actuates by a pendular movement of about 180.degree. an arming rod (4, 5) integral with one or a plurality of arming plates (6, 7). Each arming plate (6, 7) acts, through an arming trigger (8, 9), on an ejection arm (18, 19) by winding up an ejection spring; a locking stud controlled by an electromagnetic unit releases or locks each ejection arm (18, 19) in order to control the shooting; each ejection arm (18, 19) has its shooting rotation axis coaxial with the rotation axis of the arming rod (4, 5) integral with the reducer; the invention applies particularly to the launching of targets of the "rabbit" type.

Abstract: A process for the treatment of aqueous acidic liquors containing dissolved aluminum and/or iron compounds to produce an aluminum and/or iron sulfate water-treatment product is characterized by the combination of steps comprising contacting the liquor with a basic material capable of reacting with the dissolved aluminum and/or iron compound to precipitate aluminum and/or iron values, separating the precipitate in the form of a cake or slurry from the remaining liquor, treating the cake or slurry with sulfuric acid to re-dissolve aluminum and/or iron values and to produce a solution of aluminum and/or iron sulfate and separating suspended solid matter from the solution. The liquor may be a waste product from industrial processes or may be a mine effluent and the process avoids the need to dispose of these to waste.

Abstract: The composition comprises a water dispersible colloidal siliceous material, such as a swelling clay, in intimate association with a low molecular weight water soluble high charge density organic polymer, such as a polyacrylic acid or a polyamine, the ionicity of the siliceous material being significantly modified by the charge on the polymer. The composition may be produced by reacting the siliceous material and the organic polymer in an aqueous phase system at a concentration, for example, of from 5 to 25% by weight of the polymer on swelling clay solids. The composition is suitable for use as a retention/drainage agent in paper or paperboard production, preferably after the addition of a conventional high molecular weight flocculating agent.

Abstract: A composition comprising a water-dispersible ionene polymer and a water-dispersible di-lower-alkyl ammonium halide polymer (for example, a polymer of dimethyl diallyl ammonium chloride) is disclosed. These polymers are present in the composition in a ratio effective to function synergistically as an algistatic or algicidal agent when an effective amount of the composition is dispersed in a body of water. Examples of suitable bodies of water are swimming pools, spas, lakes, rivers, or water in an industrial water system, such as a cooling water system. Also, a method of treating water which is susceptible to the growth of algae is disclosed. The method is carried out by incorporating in the water an at least algistatic amount of the composition.
