Title: Improvements relating to the wet screening of solid material
IPC: B07B1/00
Filed: 1956-10-19
Abstract: 815,266. Filters. STAMICARBON, N. V. Oct. 19, 1956 [Oct. 21, 1955], No. 31951/56. Addition to 791,520. Class 46. Where the particle mixture is such that blockage of the screening deck may occur in the method of screening according to the parent Specification or any of Specifications 791,857, 791,858 and 791,859, additional particles, substantially coarser than the size at which separation is to be effected, are fed to the screen together with the liquid/solid mixture to be separated. Liquid/solid mixture is fed at 7 to a funnel 3 to which is also fed a quantity of coarse particles, e.g. small rubber spheres 1 mm. in diameter, at 12. The funnel effluent is pumped at 5 to a feed-point 14 for a screening deck 1. The additional coarse particles, together with the particles of the material to be separated which are above the size of separation, discharge off the end of screening deck 1 and are entrained in liquid 13 so as to flow with the required velocity (see the referred Specifications) along a second screening deck 2 whence the additional coarse particles (plus, optionally, some liquid) flow off to form the feed 12. The feed end of deck 2 may be provided with means for directing overflow from deck 1 along deck 2. In Fig. 3 (not shown) screens 1 and 2 are formed by successive parts of one screening deck, liquid feed 13 being omitted. Instead of separating the additional coarse particles from the "oversize" of deck 1 by the method of the "referred" Specifications, as in the Figure, this separating may be effected by a hydrocyclone or in a settling tank. Where the screening treatment is effected in a plant incorporating a grinding mill for grinding raw material to a fine condition preparatory to screening, an intermediate product from the grinder may be used as the additional coarse particles. In that case the overflow from deck 2 in the Figure is conducted back to the grinder instead of to funnel 3, and funnel 3 may be located adjacent deck 1 so that the pump 5 may be dispensed with.

Title: Method of and means for operating mechanically driven rectifiers in connection with electric transformers
IPC: H02M1/20
Filed: 1925-02-25
Abstract: 247,131. Lodge-Cottrell, Ltd., (Lurgi Apparatebau Ges.). Feb. 25, 1925. Commutator switching-arrangements.- Mechanically driven rectifiers are employed in conjunction with a tapped transformer for obtaining two or more direct currents of different voltages from a single source of alternating current. In the arrangement shown in Fig. 1, the transformer secondary winding is tapped at its centre to obtain a second series of rectified impulses of half the voltage of the transformer secondary. Lower voltage impulses of unequal magnitude may be obtained by arranging the tapping at a point other than the centre of the secondary winding. By tapping the transformer secondary winding at two points as shown in Fig. 5, lower voltage impulses of equal magnitude may be obtained. By adding to the arrangement shown in Fig. 5 a central tapping from the secondary winding of the transformer, rectified impulses of three different voltages may be obtained. Fig. 9 shows a further arrangement whereby rectified impulses of four different voltages are obtained between the leads I, II, III, IV and earth. In order that, when several rectifier discs are employed in conjunction with a single transformer, all the discs may be earthed simultaneously and at the same pole, a single rectifier disc from which no direct current is taken may be employed to effect the earthing of all the discs. The several discs may be mechanically coupled and driven by a singles synchronous motor or they may be independently driven by separate synchronous motors. In the latter case. means are provided to ensure that the discs are correctly positioned in relation to each other. The invention is also applicable to three-phase transformers, Fig. 13 showing an arrangement whereby rectified impulses of four different voltages may be obtained at the points a - - d. Specification 185,891 is referred to. Reference has been directed by the Comptroller to Specification 246,624.
