Abstract: FIELD: chemistry. 
     SUBSTANCE: invention relates to a method for producing zeolites of the ZSM-12 type with the MTW structure. According to the method, two solutions are mixed. The first solution is an aqueous solution where a pH varies from 8.5 to 9.5. The aqueous solution contains an aluminum compound and a template. A compound of the general formula (I) functions as a template. One should add a dry alkali or an aqueous solution of an alkali to the first  aqueous solution to increase a pH so that it can vary from 11.5 to 13.5. The second aqueous solution contains a silicon compound. The resulting solutions are mixed to obtain a gel-like mass. The mixture of solutions is prepared based on the following molar ratios of the components used: template/SiО 2  = 0.06-0.15, SiО 2 /Al 2 О 3  = 50-300, H 2 O/SiО 2  = 4-16, Ме 2 O/SiO 2  = 0.05-0.15, where Me 2 O may be K 2 O (in terms of KOH) or Na 2 O (in terms of NaOH). The two solutions are being mixed until a homogeneous gel-like mass is obtained. The homogeneous gel-like mass should be left for 60-90 minutes at room temperature so that the primary structure of the gel can be formed. Crystallization of the resulting gel-like mass is carried out for 96-120 hours at a temperature of 145-155C followed by the isolation of the crystalline product, which should be washed with distilled water so that a pH can vary from 7.8 to 8.3 and which should be dried to constant weight and annealed at 500 ± 10C for 8-12 hours. After that one should carry out the ion exchange reaction with an aqueous solution of ammonium salt followed by the isolation of the product. The product should be washed with distilled water until a pH reaches 7.8-8.3, dried to constant weight and calcined at 450 ± 10 ° C for 4-7 hours. Solutions of colloidal silicon dioxide or tetraethylorthosilicate are used as the silicon compound. Octadecahydrate of aluminum sulfate or nanohydrate of aluminum nitrate, or isopropoxide of aluminum, or hexahydrate of aluminum chloride is used as the aluminum compound.  
     EFFECT: invention increases the proportion of mesopores in the finished product up to 12-25% of the total number of pores when obtaining aluminosilicate zeolite.

Abstract: FIELD: iron and steel industry.SUBSTANCE: invention relates to the field of ferrous metallurgy, namely to the production of iron ore pellets. The formation of a skull on the bottom of the pelletizer is carried out and the wet charge is loaded into the pelletizer in two streams. Coal fines in the amount of 2-6% of its flow rate are fed into the first charge stream to form a coal-charge mixture and slurries of spent engine oil preheated to 30-90°C are introduced in the amount of 1-8% of the charge flow rate of the first stream. The specified mixture is introduced into the compressed air stream with the formation of a gas-coal-charge jet. A zone occupied by the charge and a zone free from the charge are formed on the bottom of the pelletizer, and nucleation is carried out by spraying the charge with a gas-coal-charge jet oriented to the skull in the zone free from the charge, to obtain a dense layer of wet charge. The mentioned dense layer of wet charge is divided into embryos, the skull is cleaned from the embryos, the shell of the pellets is formed by pre-crumpling the embryos with the charge of the second stream to the pellets and heat treatment is carried out.EFFECT: invention provides increased strength and yield of suitable pellets.1 cl, 1 dwg, 1 tbl, 1 ex

Abstract: A brake effective between a rotating part and a non-rotating part has a substantially nondeformable brake disk secured to one of the parts, centered on an axis, and having a pair of axially oppositely directed brake-disk faces. A housing is secured to the other of the parts, at least partially surrounds the brake disk, and has a pair of end walls having wall faces axially confronting the respective disk faces. Respective brake elements are limitedly axially displaceable between the wall faces and the respective disk faces and engageable with the respective disk faces. Formations on the elements and housing prevent the elements from rotating relative to the housing. Spring packs between the brake elements and the respective wall face urge the elements with a substantially constant force axially together into braking engagement with the disk. Seals between the brake elements and housing define a pressurizable chamber between the brake elements. The chamber can be pressurized to move the elements axially apart and out of braking engagement with the disk.
