Title: Novel antibiotics of agricultural fungicides, polyoxins j, k and l: and process for preparing the same
IPC: C07H19/06
Filed: 1968-06-28
Abstract: The invention comprises antifungal antibiotics polyoxins J, K and L which have the formul[mu] respectively. The polyoxins are produced by the aerobic cultivation in an aqueous nutrient medium of streptomyces cacaoi var. asoensis ATCC 19093 or 19094 or a polyoxin-producing mutant thereof (see also Specification 1,097,189). The polyoxin complex is isolated from the broth by adjusting to pH 2-0, heating to 70 C. and filtering. The filtrate is treated with activated C and is eluted therefrom with 60% aqueous acetone. A crude is obtained by adding acetone to the cone. eluate. Purification is by treatment with (a) "Dowex" 50 WX8 and elution with aqueous NaCl, (b) carbon, (c) "Dowex" 50 WX8 and elution with 0À1 M phosphate pH 2.0, (d) chromatography on sulphoethyl "Sephadex" and elution with 0À01M phosphate buffer increasing to 0À1M. The complex is dissolved in water and passed through "Amberlite" IR-4B (Cl type) to remove polyoxins D, E and F (see Specification 1,156,390). Distribution chromatography on a cellulose column using (a) butanol/acetic acid/ water (4 :1: 2) and then (b) 75% aqueous phenol results in a separation of polyoxins J, K and L and also polyoxins A and B (Specification 1,097,189). The antibiotics may be recrystallized from aqueous alcohol, e.g. aqueous ethanol. The polyoxins are amphoteric and can be adsorbed on either cation or anion exchange resins and may be eluted by acid, alkali or salt solutions. Polyoxins J, K and L may be used as agricultural fungicides.

Patent ES-406977-A1 (ES)
Title: Plural motor tension controlled tape drive
IPC: G11B15/43
Filed: 1972-09-23
Abstract: Arrangement intended in particular for driving a tape-shaped record carrier accommodated in a cassette, which arrangement is provided with two direct-current motors which each drive one reel. In the "fast forward" and "fast rewind" functions one end of each of the two motor windings is connected via a common impedance to one terminal of the supply source, the other end of the winding of the take-up motor being directly connected to the other terminal, whilst the other end of the winding of the take-off motor is connected to this other terminal of the supply source via a Zener diode. As a result the brake torque exerted by the take-off motor always is automatically regulated to a value such that the sum of the speeds of the two motors is constant. Consequently the tape tension produced is substantially independent of the friction produced. Also the time required for the "wind" functions is substantially constant.
Patent ES-408125-A1 (ES)
Title: Method for simultaneous combined production of electrical energy and crude iron
IPC: C21B11/00
Filed: 1972-10-30
Abstract: The invention relates to a method of combined production of electrical energy and crude iron, comprising reducing iron oxides while keeping the temperature below the melting point of the crude iron during a pre-reduction and above said melting point during a final reduction. The pre-reduction is made by introducing carbonaceous material and the material containing iron oxides into a fluid bed containing solid carbonaceous material, producing reducing gases in the fluid bed by partial combustion of the carbonaceous material with air/or oxygen gas, pre-reducing the iron oxides by said reducing gases until the material has achieved a metallization degree of 30-80 %, most of the heat requirement of the pre-reduction being covered by said combustion. The pre-reduced material is finally reduced and molten by being brought into contact with carbon, and the heat requirement of this final reduction and melting process is covered by electric heating. A substantial part of the exhaust gases from the reduction operations is passed to a thermal power station to generate electrical power therein.

Patent ES-448612-A1 (ES)
Title: Method and apparatus for recovering by-product silt fines from a slurry thereof
IPC: F26B17/20
Filed: 1976-06-05
Abstract: The present invention relates to a method and apparatus of recovering by-product fines, such as coal fines, by-product fines created in the manufacture and processing of metals or any very finely divided substance which may be of value when recovered to a usable form and which may be naturally found in the form of a silt or as the result of the manufacturing process, from a slurry or sludge thereof. The slurry mass is first treated to dissociate it into discreet units, if required, for further treatment to recover the fines contained within the discreet units of the slurry in the form of a usable end product. The discreet units of the dissociated slurry are conveyed through a rotary-driven impeller feed conveyor and simultaneously a hot gas such as air or superheated steam is flowed through the conveyor in contact with the slurry segments or discreet units. This combined action of the rotary impeller feed and the flow of hot air uniformly breaks up and dries the discreet slurry units into particles of desired moisture content. If additional drying is required, the present invention teaches the use of a second rotary-driven impeller feed conveyor in which the extruded agglomerates are conveyed while again simultaneously flowing a hot gas through this second conveyor in contact with the agglomerate to break up or size and further dry the agglomerates to a desired degree.
