Abstract: A transmission assembly for a lifting column is provided. The lifting column includes an inner tube. The transmission assembly includes a hollow spindle, a transmission screw, a sleeve sleeved over the hollow spindle, a guide tube limited in the sleeve, and an actuating device actuating the guide tube to rotate. The guide tube and the hollow spindle are synchronously rotatable and axially expandable and retractable relative to each other. The transmission screw and the hollow spindle are synchronously rotatable and are axially expandable and retractable relative to each other. The actuating device is disposed in the inner tube and securely mounted to an upper end of the sleeve. A lower end of the sleeve is securely connected with a first transmission nut that is threadedly-fitted with the hollow spindle, the first transmission nut is securely coupled to the inner tube, and the upper end of the sleeve is movably disposed.

Abstract: Disclosed are a phthalazinone compound, and a preparation method therefor and the medical use thereof. In particular, disclosed are a compound as represented by formula (I), and a pharmacodynamically acceptable salt, and the use of the compound as an androgen receptor (AR) for degradation.

Abstract: The disclosed embodiments provide a distributed transaction system including a group of validator nodes that are known to each other in a network but are indistinguishable to other network nodes. The validator nodes form a Committee including a Leader node and one or more Associate nodes configured to receive and process transaction requests and candidate requests, for example, to add new blocks to one or more blockchains. The Committee may be dynamically changed, such that new network nodes may be added to the Committee or may replace existing validator nodes. The Associate nodes also may coordinate with each other to select a new Leader node. The system may allow multiple request-fulfillment process to run simultaneously, thereby enhance the efficiency of the system.

The Associate nodes also may coordinate with each other to select a new Leader node. The disclosed embodiments reduce the distributed system's reliance on the stability of any particular node(s) in the network, as the validator nodes in the Committee may be changed at a sufficient frequency to remove unreliable, unavailable, or otherwise untrusted nodes.

Abstract: The present invention relates to an elevator with a function of escaping upon failure. This elevator includes a lift car, a car door, and a variable frequency controller. The lift car is provided with a rescue detecting device. When the elevator malfunctions, whether there is someone being trapped can be detected through the rescue detecting device. If there is someone being trapped, the variable frequency controller can automatically start emergency rescue operation mode, control the lift car to move to the door are, and output instruction of opening the door. The car door drives the landing door to open at the same time such that the trapped person can escape safely.
