Abstract: Disclosed is an integrated washing and spinning tub and an energy-saving and healthy household washing machine with a tub replacing function. The integrated washing and spinning tub comprises a water holding tub, a spinning tub is arranged in the water holding tub, and the water holding tub and the spinning tub are connected in a sliding groove mode. The energy-saving and healthy household washing machine with a tub replacing function comprises a washing machine shell, the integrated washing and spinning tub is arranged in the washing machine shell, a spring telescopic support corresponding to the integrated washing and spinning tub is arranged on the inner wall of the upper portion of the washing machine shell, a support frame is arranged at the bottom of the integrated washing and spinning tub, and a reduction gear and a motor which are connected are arranged on the support frame.

Abstract: The present application provides a compound refrigeration system for a heat pipe of a supergravity centrifuge. The compound refrigeration system for the heat pipe of the supergravity centrifuge includes a rotor rotating around a vertical axis, an experimental cabin covering outside the rotor, and a corresponding cooling system. The rotor is provided with a shaft part which is in running fit with the experimental cabin. The shaft part is provided with a shaft top end located outside the experimental cabin. The cooling system includes a liquid cooling device and an evaporative cooling device. The liquid cooling device comprises a refrigeration source, and a first cooling medium circulating pipeline communicated with the refrigeration source and thermally coupled with a cabin wall of the experimental cabin. The evaporative cooling device includes a condensation chamber arranged outside the experimental cabin, and a heat pipe radiator thermally coupled with the rotor.

Abstract: Provided are a process and a device for preparing environmentally-friendly insulating gas perfluoroalkylnitrile. The device comprises a first tank reactor, a second tank reactor, and a fixed bed reactor. A condensing and collecting device is provided at the top of the first tank reactor, a collecting and guiding channel at the bottom of the condensing and collecting device is connected to an inlet of a storage tank, and an outlet of the storage tank is connected to an inlet of the second tank reactor. The second tank reactor is connected to a perfluoroolefin tank. An outlet of the second tank reactor is connected to a storage gasification tank. The storage gasification tank is connected to a carrier gas tank, and an outlet of the storage gasification tank is connected to an inlet of the fixed bed reactor. The present invention starts from cyanuric chloride and perfluoropropylene, and uses two tank reactors and a fixed bed reactor to realize production with high atom economy.

Abstract: Technologies are generally described for providing an intermediary API for intercepting and processing subscribing requests to a communications server. An intermediary API may intercept a subscribing request from a local or PIC client to receive presence status data from a presentity such as a bot executed on the communications server. The intermediary API may be configured to provide the presence data to a PIC client without consuming the communications server registered subscription limit. The intermediary API may employ a server-supported protocol-specific processing language or module to intercept the subscribing requests, to determine if the request is targeted for one or more bots executed on the communications server, and to determine if the request is for presence data for one or more bots. The intermediary API may determine if the request is non-terminating, and if all criteria are met, may provide presence data to the requesting client.
