Title: Спосіб автономного визначення кута крену під час польоту аеродинамічно стійкого літального апарата по балістичній ділянці траєкторії
Filed: 2021-01-25
Abstract: Винахід належить до способу автономного визначення кута крену під час польоту аеродинамічно стійкого літального апарата (ЛА) на балістичній ділянці траєкторії. В довільний момент під час польоту по балістичній ділянці траєкторії починається інтегрування диференціальних рівнянь орієнтації з нульовими початковими умовами з використанням вимірювань датчиків кутової швидкості, вимірювальні осі яких орієнтовані по осях зв'язаної системи координат ЛА. В результаті відомі три кути Ейлера-Крилова, які однозначно характеризують положення ЛА відносно цього початкового положення. Кут крену ЛА в початковий момент ∆∆1 є довільним і невідомим. Далі, при виконанні певних умов (повороті поздовжньої осі на певний граничний кут гравітаційного розвороту відносно початкового положення), відбувається розрахунок кута крену ∆∆1, на який був повернутий ЛА в початковий момент, за формулами, в праві частини яких входять отримані на виході алгоритму орієнтації кути Ейлера-Крилова. Таким чином, стають відомі обидві складові кута крену: початкове значення ∆∆1, яке спочатку було невідоме, і приріст кута крену, що виник за час інтегрування диференціальних рівнянь орієнтації. Їх сума дорівнює шуканому куту крену виробу. Застосування даного способу дозволяє визначити кут крену з точністю близько 5°…15° при сумарній похибці вимірювань ДКШ ∆ωω0,3 /c, кутовій швидкості гравітаційного розвороту ωzgz4 /c, кроку інтегрування ∆tt0,0025 с, за умови вибору оптимальних ,п кр, n.

IPC: B23K9/12
Filed: 2004-07-21
Abstract: The invention concerns welding, in particular feed of welding wire, and it can be used at fuse welding with mechanized wire supply. A method for wire feed by means of driving roller consists in that the wire is plastically bent, directed to the working groove of the driving roller, at exterior angle, which at least is equal to 0.5 DEGREE to the tangent to circle, which passes through the point of engagement of the wire with driving roller. The wire is pressed into the working groove of driving roller, by the effort of pressing the wire is bent and engaged with working groove, the contact of the wire with working groove is maintained on the section with the length, which as minimum is equal to one diameter of wire and as maximum is equal to the length of working groove, the wire is removed from the connection with the driving roller, then it is straightened by reverse bending and direction at exterior angle, which at least is equal to 0.5 DEGREE to the tangent to circle, which passes through the exit point of disengagement of the wire from the driving roller and the wire is fed in required direction. A device contains a driving roller 1 with working groove 2, wire feed unit, mechanism of pressing 4 of wire into the working groove, wire straightening mechanism 3. The driving roller with groove is made in the form of intermediate rotary support, and the mechanism of wire pressing into the working groove is made in the form two pressing elements 4 that are the final supports for the wire, located on both sides from the area of contact of the wire with driving roller and located with possibility of displacement. Both pressing elements are made in the form of rollers or in the form of bushings with possibility of displacement in the plane of bending and along the wire. The mechanism of wire straightening is made in the form of support element installed on the housing of the device. The invention allows to increase the pushing efforts required for supplying the wire for great distances, and to ensure the high-quality straightening of wire.

Abstract: Flue gases or other contaminated humid exhaust gases which contain SO3 are cooled by an indirect heat exchange in a heat exchanger to a temperature below the dew point temperature of sulfuric acid and are cooled further to a predetermined temperature in an SO3 condenser by means of dilute sulfuric acid, which is sprayed to flow in a countercurrent to the gas, whereby dilute sulfuric acid having a predetermined concentration is condensed. The gas leaving the SO3 condenser is scrubbed and cooled to a temperature from 40 DEG  to 55 DEG  C. in a fine scrubber by a treatment with a sprayed aqueous liquor. The exit gas is reheated to a predetermined temperature in a reheater by a treatment with sprayed dilute sulfuric acid from the SO3 and after the condensation of SO3 is passed through a filter. Dilute sulfuric acid from the reheater is sprayed into the SO3 condenser. The temperature of the gas in the reheater is so selected that the water which has been absorbed is not condensed but remains in the gaseous effluent. The exit temperature of the gas leaving the heat exchanger is approximately so selected that the temperature at which dilute sulfuric acid becomes available is approximately the same as the temperature of the gas in the reheater. The rate at which dilute sulfuric acid is sprayed is so adjusted that the dilute sulfuric acid withdrawn from the fine scrubber is at a temperature which is approximately the same as the required exit temperature of the gas leaving the SO3 condenser.

Abstract: A process to eliminate lead in gasoline, at the same time maintaining a high octane number in the gasoline, by irradiating leaded gasoline, at room temperature and pressure, with U.V. rays, which generate free organo-metallic radicals which facilitate a photochemical reaction with the gasoline, eliminating "moloxides" responsible for the reduction in the gasoline's octane number. In this manner an up-graded gasoline is obtained, which is completely lead-free, and prevents atmospheric pollution.
