61 results about "Conversion procedure" patented technology

Helpful, trusted answers from doctors: Dr. Klein on cardiac conversion procedure: Experimental models (mice, chickens) have shown some benefit of Adenosine before and during cardiac surgery. However, clinical studies in actual patients have not shown as significant a benefit - similar to Adenosine treatment in patients with acute mi.

Steam stripping method of process condensate in CO conversion

The invention relates to a steam stripping method of process condensate in CO conversion. The invention is characterized in that the process condensate firstly enters the upper part of a carbon dioxide steam stripping tower for flashing evaporation; secondary steam from the upper part of an ammonia-evaporated steam stripper tower enters the bottom part of the carbon dioxide steam stripping tower and steam strips carbon dioxide by countercurrent contacting with the process condensate after flashing evaporation; the process condensate after flash evaporation and the steam stripped carbon dioxide carry out countercurrent contact; the process condensate after flash evaporation and steam stripping enters the upper part of the ammonia-evaporated steam stripper tower from the bottom part of the carbon dioxide steam stripping tower and is steam-stripped by low-pressure steam entering from a kettle of the ammonia-evaporated steam stripper tower; gas phase is treated by secondary condensation to obtain non-acid-coagulated gas and condensate sewage; and steam stripping water is obtained from the bottom part of the ammonia-evaporated steam stripper tower. The invention carries out steam stripping on the upper and lower towers to carbon dioxide and ammonia in the process condensate respectively, thus avoiding the possibility of coexistence of carbon dioxide and ammonia in a condensing system, effectively solving the problem that the steam stripping system of the process condensate in the conversion procedure occurs ammonium salt crystallization blockage and prolonging the period of stable operation of a conversion device.

Active control system and method for improving large-span bridge wind-resistant performance

The invention discloses an active control system and method for improving the large-span bridge wind-resistant performance. The active control system comprises a flow guide plate and a central stabilizer, both of which can rotate by corresponding angles according to changes of wind environments such as different wind attack angles. The active control system detects a wind environment signal through a wind environment detection processor, the signal is transmitted to a central control unit inside the system, the telescopic length of a hydraulic numerical control telescopic rod and the rotatingangles of the flow guide plate and the central stabilizer are obtained through conversion conducted by an angle conversion procedure embedded in the central control unit, a length signal is then transmitted to the hydraulic numerical control telescopic rod, and the telescopic rod stretches and retracts by the corresponding length to achieve the rotating angles of the flow guide plate and the central stabilizer. Compared with the prior art, the flow guide plate and the central stabilizer can be rotated to make gas be better divided and flow around a bridge structure, the wind-resistant performance of a bridge in different wind environments can be effectively improved, the wind-induced vibration amplitude of the bridge structure is reduced, the aerodynamic performance of the bridge is improved, and the traveling comfort of vehicles traveling on the bridge in windy weather is improved.

Water bucket type wave motor

The invention discloses a water bucket type wave motor. The water bucket type wave motor comprises a rotor and water buckets, wherein the rotor is cylindrical or annular, the water buckets are evenly distributed at the external circle of the rotor in the peripheral direction, each water bucket is of a water tank structure, openings of the water buckets are sequentially arranged along the periphery, the axis of a rotor shaft is slightly higher than the water surface and is parallel with the water surface, and the axis of the rotor shaft is roughly parallel with the bank. A one-way valve is installed on the lateral wall of each water bucket and corresponds to the opening of the corresponding water bucket, water can only enter through each one-way valve, and a water outlet is near the outer side of the bottom surface of each water bucket. Each water bucket is simple in structure, low in manufacturing cost and high in reliability. Due to the fact that the water bucket type wave motor directly collects and utilizes the potential energy of waves and floating force of water to drive the water buckets on the rotor to move for power generation, the wavy energy does not need a middle conversion procedure, and the utilization rate is high. If the geometric size of each water bucket is designed to be small, small broken waves can also be utilized.

General type body-in-white three-dimensional measuring and positioning device and positioning method

The present invention discloses a general type body-in-white three-dimensional measuring and positioning device and a positioning method. The device comprises a bottom plate, a main positioning mechanism and a body-in-white vehicle supporting mechanism, wherein the main positioning mechanism and the body-in-white vehicle supporting mechanism are arranged on the bottom plate. The main positioning mechanism comprises a supporting sleeve rod and a plurality of rotatable main positioning pins. The lower end of the supporting sleeve rod is provided with a supporting disc. The plurality of rotatable main positioning pins are arranged at the upper end of the supporting sleeve rod. The supporting disc is provided with a spherical cavity and a rectangular groove which is inwardly extending along the axis of the supporting sleeve rod. The two shorter side surfaces of the rectangular groove are tangent to the spherical cavity. The spherical cavity is internally provided with a connection swivel piece matched with the spherical cavity. The lower side of the bottom plate is correspondingly provided with a locking oil cylinder corresponding to the supporting sleeve rod. The piston rod of the locking oil cylinder upwardly passes through the bottom plate to be in threaded connection with the connection swivel piece. The main positioning mechanism and the bottom plate are flexibly connected, so that main positioning pins can be conveniently aligned with positioning holes in a body-in-white vehicle. The device and the method can be applied to the body-in-white three-dimensional measurement of multiple types of vehicles, and the advantages of simple conversion procedure and high positioning efficiency are realized. Meanwhile, the positioning mechanism is not easily damaged.
