Abstract: An apparatus for a lighting device with a rotatable support includes a lamp body, the lamp body is provided with the support capable of rotating relative to the lamp body, the support is provided with a magnetic block, and a lighting port of the lamp body is arranged on the side wall of the lamp body toward the direction of the rotation center line of the support. When the adjustable lighting device is used, the support is fixed on a metal object in a place to be illuminated through the magnetic block and the side face direction of the lighting port of the lamp body can be adjusted by adjusting the lamp body to rotate relative to the support, and therefore the side face lighting angle of the lighting port is adjusted, and due to the fact that the lamp body can rotate relative to the support at any angle, stepless adjustment of the side lighting angle of the lighting port can be achieved.

Abstract: A microbubble generation device comprises a liquid inlet (101), a gas inlet (104), a bubble flow outlet (103), and a gas-liquid mixing chamber (102). An air-permeable hole having an angle structure is provided at a gas-liquid interface of the gas-liquid mixing chamber (102), and a pointed end of the angle structure of the air-permeable hole points to a liquid flow direction. The bubbles generated by the device are extremely small in diameter, prolonging a duration the bubbles stay in the liquid phase, and enhancing gas-liquid mass transfer efficiency.

Abstract: The present invention discloses a novel demister, comprising at least one demisting unit; wherein the demisting unit comprises a glow guide cylinder, a cyclone blade group mounted at a gas inlet of the glow guide cylinder and a liquid collection cylinder arranged outside the flow guide cylinder, wherein the liquid collection cylinder is provided with at least one glow guide cylinder, a water permeable structure is arranged on a side wall of the flow guide cylinder, and a gap is defined between an outer wall face of the flow guide cylinder and an inner wall face of the liquid collection cylinder and an interlayer chamber is formed.

Abstract: The present invention provides a blade group for demisting and dedusting, comprising a plurality of blades that are annularly arranged and a support mechanism for fixing the blades; wherein the blade comprises a section of curved plate, a cross section of the curved plate being a gradually-varied arc curve whose curvature increases progressively along an airflow direction. When gas carrying fine mist droplets or fine dust particles are passing through the blade group for demisting and dedusting, since the gas is different from the mist droplets or dust particles in terms of mass, separation of the gas from the liquid or dust under the effect of inertia is promoted. Especially, the gradually-varied blade curve enables the droplets or dusts to be captured and removed efficiently under the effect of a constantly-varied inertia and a drag force, which remarkably improves the working efficiency in combination with a washing device.

Abstract: The present invention relates to a polyimide precursor and a lithography pattern formed by the same. The polyimide precursor has a repeating unit having a structure of formula (I): in the formula (I), Ar represents a tetravalent group derivated from a tetracarboxylic dianhydride compound; R1 represents a divalent group derivated from a diamine compound; and R2 independently represent a thermal-crosslinking group, a photosensitive-crosslinking group, or a hydrogen atom. The polyimide precursor has an excellent pattern-forming ability.

Abstract: The present invention discloses a sidewall structure of a hopper car, including: an integrally formed upper side beam (1), an integral sidewall panel (2), an integrally formed lower side beam (3) and a lower sidewall (4), wherein the upper side beam (1) is riveted with the integral sidewall panel (2) at the lower side; the sidewall panel (2) is riveted with the integrally formed lower side beam (3) at the lower side; the sidewall panel is of a panel-column structure in which the wall panel is integrated with a side column, and the side column is arranged at the inner side of the car body; the lower side beam (3) is riveted with the lower sidewall (4) at the lower side.

Abstract: A full-vagina sleeve cylindrical expansion and pneumoperitoneum integrated device, includes: an elastic embedded ring (1) and a sleeve (2). The elastic embedded ring (1) is made of elastic material and embedded inside a pelvic outlet. The elastic embedded ring (1) is capable of expanding in a natural state inside a vagina to tightly adhere to wall of the vagina, or being inflated into an annular ring which tightly adheres to the vagina wall so as to elastically expand a vagina tissue. The sleeve (2) is made of elastic material or a non-elastic material and is cylinder-shaped. A front end ring of the sleeve (2) is connected with the elastic embedded ring (1), and a rear end ring extends out of the vagina. An operation mask (3) is fixedly provided on the rear end ring.

Abstract: A search engine communicates with a broker to identify search result content associated with merchants that support purchases through an electronic commerce system provided by the broker. The results of a search can include some content associated with merchants that support purchases through the broker, some content associated with merchants that do not support purchases through the broker, and some content not associated with any merchant. The search engine visually distinguishes content in the search results associated with merchants that support purchases through the broker by displaying a badge, such as a graphical icon, with the content. The search engine can use different types of badges to indicate different characteristics of the merchants.
