Patent ES-270291-A1 (ES)
Title: Stabilized herbicidal composition and method of employing the same
IPC: C07C329/00
Filed: 1961-09-07
Abstract: Thioncarbomethoxy disulphide (CH3O-CS-SS-CS-OCH3) is stabilized by the addition thereto of at least one acid of formula RCOOH, where R represents an alkyl group having 1 to 4 carbon atoms, in a quantity based on the disulphide not exceeding 5% by weight, 0.1-2% generally being sufficient. The preferred stabilizers are acetic acid and propionic acid. In tests carried out in a solvent (mainly xylenes), containing a mixture of alkyl aryl sulphonate and an ester of a polyethylene glycol ether as emulsifier, the stabilizing effect of acetic acid on the disulphide was compared with the effects of dichloroacetic acid, formic acid and pyridine. The stability of the disulphide in the absence of a stabilizer was also examined comparative tests were made on thioncarboethoxy and thioncarboisopropoxy disulphides. In another series of tests, the stabilizing effect of acetic acid was compared with that of propionic, hexoic and octoic acids. Thioncarbomethoxy disulphide was prepared by reacting methanol, carbon disulphide and sodium hydroxide to form a solution of sodium methyl xanthate which on treating with chlorine gave the desired product. The stabilized disulphide is useful as a herbicide (see Division A5).ALSO:A stable herbicidal composition comprises thioncarbomethoxy disulphide (CH3O-CS-SS-CS-OCH3) as the active ingredient and at least one acid of formula R COOH, Where R represents an alkyl group having 1 to 4 carbon atoms, as a stabilizer in an amount not exceeding 5% by weight based on the disulphide. The composition may contain a suitable carrier such as a hydrocarbon, e.g. a xylene, and an emulsifier, e.g. a mixture of an alkyl aryl sulphonate and an ester of a polyethylene glycol ether. The preferred stabilizers are acetic acid and propionic acid. The composition is suitable for use as a contact-herbicide, and may be employed in combination with other herbicides, e.g. isopropyl N-(3-chlorophenyl)-carbamate. The action of thioncarbomethoxy disulphide on garden-cress is compared with that of thioncarboethoxy and thioncarboisopropoxy disulphides.
Patent ES-271586-A1 (ES)
Title: Improvements in or relating to continuously treating powders with gases
IPC: G11B5/706
Filed: 1961-10-28
Abstract: A non-ferromagnetic powder is wholly or partly converted to a ferromagnetic state by treatment with a gas by effecting the treatment in a zone along the outside of which an endless conveyer bearing a plurality of magnets moves. The ferromagnetic content is thus selectively conveyed. As shown in the Figure, finely divided Fe2O3nH2O (0 \sEn\sE 1.2) is supplied to glass tube 4 surrounded by heating elements 5 <PICT:0958070/C1/1> which raise the temperature to 300-400 DEG C. A conveyer belt 6 carries a row of permanent magnets 8 which are moved adjacent the tube 4. A reducing gas e.g. N2H2 is supplied through nozzle 11 in the upper part of tube 4, thus producing ferromagnetic Fe3O4 which is passed along the tube under the influence of said magnets and passes into a zone of inert gas e.g. nitrogen supplied radially at nozzle 13, said zone preventing admixture of the reducing gas with an oxidizing gas e.g. N2 + air supplied to the lower part of tube 4 by nozzle 15 where oxidation takes place, the temperature being maintained at 230-280 DEG C., to produce g -ferric oxide which is continuously discharged into collecting chamber 18.

Patent ES-321758-A1 (ES)
Title: Fuse for a non gyrating projectile
IPC: F42C9/04
Filed: 1966-01-05
Abstract: A direct action fuze for non-rotating projectiles provided with safety means and a spring-actuated rocker 37 to control arming comprises a locking device 17 which prevents movement of the rocker 37 before launching of the projectile and also prevents movement of a striker bolt, the device 17 being arranged to slide longitudinally in the body of the fuze. On the fuze body 1 is a cover 2, which can be rotated to set the fuze for instantaneous or delayed action on impact. On assembly of the cover and body, a screw 8 is tightened to force apart the ends of an elastic ring 5 so that the ring engages a seating 7 in the cover and prevents separation. A seal 4 is provided between the body and the cover and a cap 3 having a crushable part 49 is secured on cover 2. In the safety position, instantaneous and delay primers 30, 31 housed in a rotatable carrier 11 are out of alignment with the striker 9 and a pyrotechnic train leading to a detonator 54. When cover 2 is rotated to set the fuze, a depending finger 28 rotates the carrier 11 until the selected primer is in line with striker 9. This rotation brings a recess in the cover into register with balls 14, 15. On launching the projectile, the balls 14, 15 move outwards and release the member 17, which sets back due to inertia against its support spring 21. A leaf spring prevents return movement of the member 17. Movement of the bolt 10 is prevented by a ball 24 supported by a rod 27 bearing against a spring-stressed rack 12 housing a primer (41), Fig. 9 (not shown). Rearward movement of the member 17 brings a recess into line with rocker 37, which is connected through a clockwork gear train to the rack 12. With the rocker 37 freed, spring 39 drives the rack 12 transversely of the fuze until primer (41) is aligned with a flash passage 38. As the rack moves from under rod 27, the bolt 10 is freed and a torsion spring (not shown) rotates the bolt and so frees the striker. The fuze can then operate on impact either by the striker 9 being driven inwards, or if the blow is a glancing one by momentum of the carrier 11. To test the fuze, the carrier 11 may be replaced by one containing inert material. After testing the rack 12 may be returned to its initial position by inserting a rod through an opening 51 normally closed by a plug. The movement of the gear train is reversible.
