Abstract: Устройство для подавления шума содержит микрофон, усилитель электрических сигналов, один или несколько вибраторов и излучающую поверхность (диффузор). Микрофон улавливает звуки шума, преобразует их в электрические сигналы, усиливаемые усилителем и, затем подаваемые на вибраторы, которые заставляют колебаться излучающую поверхность в противофазе приходящим волнам шума и, в результате интерференции, излучаемых волн с волнами шума, гасить последние. Излучающая поверхность (диффузор) имеет форму волновой поверхности приходящих волн шума, вибраторы расположены с наружной стороны этой поверхности, а микрофон с внутренней. Вибраторы меняют фазу колебания на противоположную при перемене полярности питания. Устройство может быть использовано для подавления шума, проникающего через окна в помещение снаружи и для предотвращения перехода звуковой информации из помещения наружу через окна. Обеспечено равномерное ослабление шума во всей зоне подавления. 1 ил.

Title: Method and apparatus for selectively separating hydrogen sulfide
Inventor: EHRIK SIMONSSON
IPC: B01D53/48
Filed: 1994-09-07
Granted: 1998-09-27
Abstract: FIELD: gas treatment. SUBSTANCE: liquid absorption method is applied for selectively removing hydrogen sulfide from gas containing both hydrogen sulfide and carbon dioxide. In the first process stage, gas 3 in tank 1 is brought into contact in at least one step with carbonate-containing alkaline solution with pH controlled during absorption period by addition of alkali such as sodium hydroxide. In the second stage, gas is burned out in combustion device 32 to convert remaining hydrogen sulfide into sulfur dioxide that is then absorbed by solution containing alkali such as sodium hydroxide in scrubbing apparatus 36. Combining hydrogen sulfide absorption with carbonate-containing solution in the first stage and burning remaining hydrogen sulfide and absorption of resulting sulfur dioxide by alkali solution in the second stage gives rise to complete separation of hydrogen sulfide with high selectivity. EFFECT: enhanced process and economical efficiency. 13 cl, 2 dwg, 1 ex
