Abstract: A gas infusion tank for a beverage machine includes a tank body defining a holding space for accommodating beverages. A mixing element includes a mixing chamber, an ascending pipe, and a descending pipe. A top of the ascending pipe is fluidly connected to the mixing chamber and a bottom of the ascending pipe has a liquid inlet. The liquid inlet is fluidly connected to the holding space. A top of the descending pipe is fluidly connected to the mixing chamber and a bottom of the descending pipe includes a liquid outlet in fluid communication with the nozzle. A gas intake hole connects the holding space with the mixing chamber.

Abstract: An ultrahigh-pressure acid-fracturing isodiametric hose assembly, comprising a hose body and a metal joint. The metal joint comprises an inner tube, a first outer tube the inner tube, and a second outer tube. The first outer tube and the second outer tube each is an independent pressing part. An external groove is provided at an outer wall of the inner tube. An end of the first outer tube comprises an internal ridge which matches the external groove for snapping. The terminal of the inner tube comprises a connecting portion. An outer wall of the inner tube comprises a first protrusion, and an inner wall of the first outer tube comprises a second protrusion engaging with the first protrusion. The hose body is clamped between the first protrusion and the second protrusion that are engaged. An inner wall of the second outer tube comprises multiple micro-protrusions.

Abstract: Verification of the address connections of a memory (14) having multiplexed banks rows and columns commences by selecting a first address location having a bank/row/column value and then writing a pattern to a second location corresponding to the first location where one of the column, row, bank addresses could become stuck high or low. A second pattern gets written to the first location and a comparison occurs between the second pattern and first pattern written to the second location. If the data is the same, then that particular row/column/bank addresses is stuck.
