Abstract: 1346911 Benzofuran derivatives ROCHE PRODUCTS Ltd 20 April 1972 [20 April 1971] 10043/71 Heading C2C The invention comprises compounds of formula and their acid addition salts, wherein R is Me 2 CH, Me; CHCH 2 , MeEtCH or Me 3 C and Z is R<SP>1</SP>CONH- or R<SP>2</SP>SO 2 NH; R<SP>1</SP>, R<SP>2</SP> being alkyl, alkenyl or aryl, or R<SP>1</SP> being also alkadienyl, alkynyl, cycloalkyl, cycloalkyl-alkyl, aryl-alkyl, aryl-alkenyl or aryl-alkynyl, the (generic) aliphatic and cycloalkyl groups containing up to 7 carbon atoms each. These compounds are prepared by reducing a nitro-2-haloacetylbenzofuran (obtained from the nitro-2-acetylbenzofuran) to the nitro - 2 - (2 - halo - 1 - hydroxyethyl)benzofuran which may be dehydrohalogenated to the corresponding oxiran, and either the halohydrin or the oxiran is reacted with (a) RNH 2 to give the nitro-2-(2-RNH1-hydroxyethyl)benzofuran (II), or (b) RNHCH 2 Ph to give its N-benzyl-II derivative, and in either case reducing the nitro group to give the corresponding diamine which is then acylated to give a compound of the above formula in case (a), or its N-benzyl derivative in case (b), the latter being finally hydrogenolysed. Where the latter derivative is isolated in the form of its O-aceylate, the latter is hydrolysed prior to hydrogenolysis. Compound II is obtained alternatively by reacting nitro-2-(1,2- dioxoethyl)-benzofuran with RNH 2 and an alkali metal borohydride. Therapeutic compositions for oral, parenteral or rectal administration comprise compounds of the above formula, which posses a selective beta-adrenergic blocking activity on the betareceptor sites of the heart, but not of the lung.

Abstract: Apparatus for admitting a cleaning agent into the vacuum line of an animal milking installation has a reservoir the lower portion of which communicates with an intake portion of the vacuum line, a metering device having a vessel which is installed in the upper portion of the reservoir, valved conduits which connect the vacuum line with a source of water and with the upper part of the vessel, a source of cleaning agent which is connected to and admits into the vessel cleaning agent when the vessel is connected to the vacuum line, a buoyant valve element which floats on the supply of cleaning agent in the vessel and seals the vessel from the vacuum line when the supply of cleaning agent in the vessel rises to a predetermined level, and a valve which allows the supply of cleaning agent to flow into the reservoir when the pressure differential between the interior of the vessel and the reservoir decreases to a predetermined value subsequent to sealing of the vacuum line from the interior of the vessel. The pressure differential decreases owing to the provision of a flow restricting orifice which connects the interior of the vessel with the surrounding atmosphere or with the interior of the reservoir.

Title: Distribution on a receiving surface of fibres carried by a¹gas current
IPC: D04H1/00
Filed: 1982-08-05
Abstract: The invention relates to the distribution on a receiving device of fibers carried by a gas current. To improve the distribution, the gas current carrying the fibers is subjected to the action of a gas layer which envelopes the current and of which the direction of flow in a plane tangent to the gas current differs from that of the gas current. The action of the gas layer results in an expansion of the current carrying the fibers. The invention is particularly useful where the fibers are received on a collecting device such as a foraminous conveyor belt, of large width.

Title: Treatment of residues from ferriferous zinc ores.
IPC: C22B19/30
Filed: 1978-12-29
Abstract: The present invention relates to a process for treating residues from a primary leaching of ferriferous zinc ores by sulphuric acid, with a view to recover a leadbearing by-product, such process comprising a secondary leaching of said residues, by sulphuric acid, within several countercurrent stages, at a temperature comprised between 85 DEG and 100 DEG C., the solid residues of the successive stages being circulated from the first to the last stage, the residue of this last stage being the said lead bearing by-product, whereas the various solutions separated from the second to the last stage are each recycled within the leaching operation of the respectively foregoing stage, and the dual zinc and iron sulphates solution, as separated from the first stage, being the principal product of the treatment. The primary leaching consists essentially of the chemical attack of the zinc oxide of the ore (naturally oxidized ore or roasted sulphur-based ore) by sulphuric acid and yields, as product, the zinc sulphate solution, which after purification, is used for the electrowinning of the zinc contained, whereas the solid residue from this primary leaching, when ferriferous ores are involved, is subject to the above said secondary leaching, in order to recover separately its zinc as sulphate solution, its iron as a precipitate and its lead as final residue of lead sulphate.
