20150295324 | ULTRA-WIDEBAND ANTENNA - The present invention relates to ultra-wideband (UWB) directional circular-field-polarization antennae. The technical result consists in development of a UWB antenna in which a unidirectional radiation is naturally generated within a wide or ultra-wide frequency band and generally does not require the use of an absorber on a back side of a radiating element. The UWB antenna comprises: a dielectric substrate; at least one feed line formed on the dielectric substrate; a spiral radiating element formed on the substrate and coupled to said at least one feed line; at least one additional dielectric substrate arranged in parallel with and above said dielectric substrate, wherein a flat printed cavity of an axially-symmetric shape is formed on said at least one additional dielectric substrate, said cavity being arranged coaxially with the spiral radiating element. | 10-15-2015 |

20150136009 | EQUIPMENT AND METHODS FOR OPERATING GEOPHYSICAL BOTTOM STATIONS - An equipment complex for deploying and recovering marine geophysical seismic or electric-survey bottom stations is mounted on a ship. The complex includes—a powered capstan, —rotatable turntables and rolls, —load-bearing units connected to the bottom stations by various fasten means and capable of winding onto the capstan and turntables, a work platform supporting a bottom station placed thereon, —an indicator for registration of the bottom stations' coordinates, mounted on the platform, —a limit switch mounted on the platform, switching ON when the bottom station is placed on the work platform, and OFF when it's removed therefrom providing for operation of the indicator. The complex may include floating buoys, damping loads, and halyards for deploying the stations. Methods for deploying and recovering the bottom stations using the equipment complex are described. Some recovering methods contemplate winding the load-bearing units onto the capstan, while switching the turntables for each subsequent load-bearing unit. | 05-21-2015 |

20080214872 | METHOD FOR THE PRODUCTION OF PHENOL AND ACETONE - A method for the production of phenol and acetone from a cumene hydroperoxide mixture comprises: decomposing the cumene hydroperoxide mixture in the presence of a catalyst mixture to form a mixture comprising phenol and acetone, wherein the method further comprises: a) forming the catalyst mixture in a catalyst formation reactor by combining sulfuric acid and phenol in a weight ratio of from 2:1 to 1:1000; b) holding the catalyst mixture in the catalyst formation reactor at a temperature of about 20 to 80° C. for about 1 to 600 minutes; and c) adding the catalyst mixture to the cumene hydroperoxide mixture to form the phenol and acetone mixture. Running the process in this manner reduces the yield of hydroxyacetone and, consequently, improves the quality of the commercial phenol. Moreover, this method reduces consumption of sulfuric acid in comparison with the process in which sulfuric acid is used as catalyst. | 09-04-2008 |
20080214873 | METHOD FOR THE PRODUCTION OF PHENOL AND ACETONE - A method for the production of phenol and acetone from a cumene hydroperoxide mixture comprises a first stage and a second stage and at least two serially connected reactors, wherein the first stage comprises decomposition of a cumene hydroperoxide mixture in the presence of a catalyst mixture to form a dicumyl peroxide mixture, and the second stage comprises formation of a phenol and acetone mixture from decomposition of the dicumyl peroxide mixture formed in the first stage, wherein, the first stage further comprises: a) forming a catalyst mixture by combining sulfuric acid and phenol in a weight ratio of from 2:1 to 1:1000 in a catalyst formation reactor, b) holding the catalyst mixture in the catalyst formation reactor at a temperature of about 20 to 80° C. for about 1 to 600 minutes; and, c) adding the catalyst mixture to the cumene hydroperoxide mixture to form the phenol and acetone mixture. The proposed method permits a significant reduction in the yield of hydroxyacetone that causes deterioration in the quality of commercial phenol. | 09-04-2008 |
