20080220732 | Method for Stabilising Time Position of an Ultrabandwidth Signal and a Live Object Monitoring Locator for Carrying Out Said Method - The invention relates to search and rescue service and can be used for debris active sounding. Said invention makes it possible to improve interference protection related to a temperature, the operator hands motion and trembling effecting the locator operation. The inventive method consists in forming an ultrabandwidth signal (UBW) according to a reference signal, in emitting the thus formed UBW signal to space, in receiving the UBW signal, in processing the UBW signal by correlating it with a reference UBW signal, wherein while processing the received UBW signal, the reference UBW signal is delayed for a time during which the initial position of a check point on a middle section between the maximum and minimum voltage of the correlated signal is set, in periodically monitoring the position of said check point and in modifying the space emission delay of the formed UBW signal when the check point position shifts from the initial position thereof, thereby resetting the check point position. | 09-11-2008 |

20150275381 | METHOD AND APPARATUS FOR LINING THE CATHODE OF THE ELECTROLYTIC CELL - The invention relates to method and apparatus for lining the cathode of the electrolytic cell. The method comprises filling the cell's shell with powder material, leveling it with a rack, covering the fill material with a dust-proof film, and compaction. Compaction is performed in two stages: preliminary static and final dynamic treatment by consequent movement of static and dynamic work tools of compaction along the longitudinal axis of the cathode of the electrolytic cell through a cushion, which is made of at least 2 layers: a lower layer, which prevents pushing powder material forward in the direction of travel, and an upper layer, which provides for a coupling between the cushion and the static work tool. Static treatment unit of the apparatus is designed in the form of a roller with a drive, is connected to a dynamic treatment unit with a vibratory exciter by means of elastic elements, providing for a simultaneous movement relative to both the horizontal and vertical axes of the roller. The invention helps slow down the rate of penetration of molten fluoride salts into the cathode thermal insulation and increase the operating life of the cell. | 10-01-2015 |
