Abstract: An adaptive sealing device for pipeline porous leakage. The device includes a pressure protection device and an encircling sealing rubber cover. The pressure protection device is used to pressurize and seal the pipeline by the encircling sealing rubber cover. The device further includes a control mechanism connected with the pressure protection device for adjusting the sealing pressure of the pressure protection device on the pipeline. The device further includes an anti-retraction mechanism connected with the pressure protection device and the control mechanism for limiting the pressure protection device and/or the control mechanism.

Abstract: The embodiment of the present disclosure provides a recovery device for oil spilling on water, a control method thereof, and a recovery vessel. The recovery device includes a casing, a control center, a variable pressure airbag, an oil detector, an isolation layer, a water suction pump, and a drain pipe. The casing is of a hollow structure, the hollow structure is used to accommodate an oil-water mixture and used as a temporary oil collection tank, the upper part of the casing is provided with an oil-water mixture inlet, the bottom of the casing is provided with a drain port, and the side wall of the casting is provided with an oil suction port. The variable pressure airbag is arranged outside the casing, and the variable pressure airbag is configured to adjust buoyancy of the recovery device. The water suction pump is configured to pump out water in the casing and discharge water to a water environment outside the casing through the drain pipe.

Abstract: The embodiments of the present disclosure provide a detachable anti-vibration sealing protection device for a pipe flange. The protection device includes a casing, wherein left and right end surfaces of the casing have through holes for the pipeline to pass through, and the casing has an accommodation cavity for placing the flange; a first shock absorption assembly for radial shock absorption of the flange; and a second shock absorption assembly which is installed in a one-to-one correspondence with the flange and is configured for axial shock absorption of the corresponding flange. The first shock absorption assembly and the second shock absorption assembly are installed in the accommodation cavity.

Abstract: Disclosed is a shielding process for SIP packaging, including: providing a circuit board; cutting the covering layer to form half-cut trenches separating different SIP packaging modules from each other, and to form grooves in each single SIP packaging module; forming a metal overlay, the metal overlay on an outer surface of the SIP packaging module and at positions where the half-cut trenches are located constituting a conformal shielding, the metal overlay at positions where the grooves are located constituting a compartment shielding; and cutting the half-cut trenches to obtain a plurality of SIP packaging modules that are separate from each other.

Abstract: Provided are the use of poly(N-isopropylacrylamide-co-butyl methacrylate) in preparing an embolism material for blood vessels, an embolism material for blood vessels and the use thereof in preparation of drugs. The embolism material for blood vessels comprises poly(N-isopropylacrylamide-co-butyl methacrylate) and a dispersion medium consisting of an electrolyte, a contrast agent, a pH regulator and water. The concentrations of the polymer, electrolyte and contrast agent are respectively 5-30 mg/ml, 0.1-30 mg/ml and 100-350 mg/ml based on iodine. The embolism material for blood vessels is suitable for embolization therapy of tumors in hypervascular and parenchymal visceral organs.
