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: A method for measuring deformation of dummy rib, includes: controlling a plurality of laser device groups to slide along corresponding curve segments respectively, and executing the following steps when the laser device groups slide to each sampling point, to obtain a degree of deformation at a position, corresponding to the sampling point, on to-be-measured dummy rib, the following steps including: controlling a laser range finder to emit a laser beam in a normal vector direction of a tangent corresponding to a position on a slide rail; determining whether the laser range finder receives corresponding reflected laser. This embodiment can have advantages of simple operation, low cost, and high accuracy.

Abstract: A method for scaling a vehicle crash dummy model, includes: obtaining a height ratio, a girth ratio, and a mass ratio of each part of a body shape of a target population to a reference population; calculating part scaling ratios of the target population to the reference population in a height direction and each direction in a girth plane according to the height ratio, the girth ratio, and the mass ratio; scaling simulation models of each part of a dummy simulation model of the reference population according to each scaling ratio; and assembling scaled models of each part, to obtain a dummy simulation model of the target population. This embodiment improves a shape simulation degree for a real human body of a dummy.

Abstract: This disclosure discloses a radiative cooling optical filter, comprising a substrate. One side of the substrate is polished, and the rough side of the substrate is provided with a metal reflective layer. The polished side of the substrate is subsequently provided with the intermediate layers and a top layer. The intermediate layer comprises alternatingly arranged layers A and layers B. The thickness of each layer A and layer B is 50-400 nm. The material of the layer A is silicon dioxide or aluminum oxide, and the material of the layer B is titanium dioxide, silicon nitride or silicon carbide. The material of the top layer is ytterbium fluoride, yttrium fluoride or zinc sulfide. The intermediate layer and the top layer jointly constitute a multi-resonant absorption enhancer in the atmospheric transparent window.

Abstract: A noise reduction nailer and a speed adjusting assembly are described. The speed adjusting assembly may comprise a speed adjusting nut and a speed adjusting member matched with it. The speed adjusting member comprises a cover cap and a sear holder return spring fixed on the cover cap. Firing pins assembly with different heights are uniformly provided on a side wall of the sear holder return spring. The speed adjusting nut is composed of two speed adjusting rings with different diameters. A firing pin spring is provided on an inner side wall of the large-diameter speed adjusting ring and the large-diameter speed adjusting ring is adapted to the sear holder return spring. The speed adjusting assembly can adjust the shooting power of the nailer for different base bodies, and can use a steel ball to act on a small head cone of a pawl to automatically reset the pawl.
