Abstract: An aerial transfer carriage and a control method therefor. The aerial transfer carriage includes: a carriage frame, a spreader, a lifting device and an anti-sway device. The anti-sway device includes two correction winch mechanisms and two correction ropes. The lifting device drives an end of each of the two correction ropes to be reel and unreel. The two correction winch mechanisms respectively drive another end of each of the two correction ropes to be reel and unreel. When it is required to correct a deflection of the spreader, the two opposite ends of the correction rope are wound or unwound respectively, and with the two correction ropes disposed crosswise, the correction rope adjusts a lateral position and a longitudinal position of the spreader during reel and unreel.

Abstract: Wireless communication between a mobile device or user equipment (UE) having a plurality of antennas and a base station includes signaling a reduced capability with respect to a number of antennas used for an uplink transmission. To reduce UE power consumption, e.g., when a battery is low and/or when a throughput is low, a UE may signal a lower capability, such as one that uses fewer antennas than the UE has available for an uplink transmission. The UE may then deactivate RF circuitry coupled to one or more antennas to reduce power consumption without significantly reducing performance.

Abstract: A compressible and highly flexible plugging agent comprises the following components in parts by weight: 70-80 parts of natural rubber, 0.5-1 part of polyacrylamide (PAM), 1.5-3 parts of polyanionic cellulose (PAC), 0.5-1 part of biopolymer XC and 10-15 parts of ultrafine calcium carbonate; and the preparation method thereof comprises the following steps: adding the components in the weight parts into the natural rubber in order according to the common preparing method at normal temperature and pressure, mixing and stirring evenly, drying and then grinding into particles of 0.05-50 mm. The plugging agent is characterized by wide raw material sources, simple process, safe application, high plugging ratio and high compressibility, which is suitable for oil recovering and geological drilling applications.
