45results about How to "Improve activity efficiency" patented technology

An improved mechanism for sharing information between a non-voice session and a voice session is described. Clients use communication devices to exchange voice information over voice sessions to voice node servers and exchange non-voice information over non-voice sessions to WAP gateways. Information about the activity in a session is stored as context data. When a client switches from communication over one type of session to another, context data for that client is located and retrieved. The retrieved context data is used to recreate the state of the prior session, thus eliminating the need to reenter information that was previously available.

The invention provides a drum which is simple in structure, convenient to process and improved in efficiency. The drum comprises a frame and a hollow drum body arranged on the frame. The hollow drum body comprises a barrel, and a first end cover and a second end cover which are arranged at two ends of the barrel. An inlet and an outlet are formed in the middle of the barrel. A first rotating shaft is arranged on the outer side of the first end cover. A second rotating shaft is arranged on the outer side of the second end cover. The first rotating shaft and the second rotating shaft are respectively arranged on the frame. Flexible components are respectively arranged at two ends of the opposite surfaces of the firs end cover and the second end cover. The inlet and the outlet are respectively formed between the flexible components at two ends. Each flexible component comprises a first sliding rod, a second sliding rod, a first sliding chute, a second sliding chute and a plurality of springs. Rows of stay bars are symmetrically arranged on two sides of the inner wall of the barrel respectively, and located at the outer sides of the first sliding rods, between the first sliding rods and the second sliding rods and at the outer sides of the second sliding rods. Lug bosses are arranged on the stay bars. Pressing blocks sleeve the stay bars. The moving efficiency of raw hides and the like in the hollow drum body is improved, and the novel drum is energy-saving and reliable.

The invention discloses a water-based environment-friendly fine mounting glue, which is composed of the following raw materials: a pre-emulsifier, a seed monomer, an dropping monomer, an initiator 1, an initiator 2 and a functional additive. The fine mounting glue produced by the invention is environment-friendly and healthy, does not have bad smell or contain harmful substances such as toluene, dimethylbenzene and heavy metals, and has the advantages of high solid content and high toughness. The mounting product hardly wrinkle or deform. In addition, the glue has fast drying speed at room temperature, high yield efficiency, good stain cleaning performance and coating performance, and initial adhesion and lasting adhesion reaching the process requirements for a hardcover gift box.

The invention discloses a composite non-precious metal denitrification catalyst and a preparation method thereof, which are realized through the process of coating evaporation, no toxic or polluting substances will be produced in the whole process, and the whole process is environmentally friendly and clean; at the same time, the raw materials used are high-purity The target material does not need to be filtered to remove impurities such as nitrate and chloride ions during the preparation process, which not only reduces the toxic pollution of the catalyst by the above impurities, but also reduces the preparation steps, improves the activity of the catalyst and the utilization rate of raw materials, and improves the utilization rate. Reduced raw material usage.

The invention discloses a high-efficiency leakage-resistant rotating drum which comprises a machine frame and a hollow drum body, wherein a leakage-resistant tank is arranged below the drum body; one side of the leakage-resistant tank towards the outer surface of the drum body is provided with a cambered groove; the cambered groove is arranged in the circumferential direction of the drum body, and the heights of the openings on the two sides of the cambered groove are greater than the liquid level in the inner cavity of the drum body; the lower end of the leakage-resistant tank is provided with a liquid outlet pipe communicated with the cambered groove; the liquid outlet pipe is provided with a liquid outlet valve; elastic devices are uniformly distributed on the inner surface of the drum body in the axial direction of the drum body; and the elastic devices are connected with a wide partition board which can elastically rotate around the elastic devices. The high-efficiency leakage-resistant rotating drum can collect the treatment liquid leaked by the rotating drum to prevent pollution, and has the advantages of low breaking tendency of the hide, low working resistance and higher efficiency.
