Abstract: An air compression device is applied in an air compressor. A rotatable pressure regulating disk and a valve are disposed in a rotor set. When external air enters an air chamber in the rotor set, the air is exhausted after being compressed through rotation of a first rotor and a second rotor. When the two rotors compress the air, a user may control the pressure regulating disk to rotate to advance or postpone exhaust of the air from the valve, so as to change an exhaust pressure in the air chamber to adjust an exhaust volume output by the rotor set. An adjustable air intake disk may further be added, so that timing adjustment can be performed during both air intake and exhaust.

Abstract: The present invention relates to a new polymerization process which is suitable for polymerizing high molecular weight products of high viscosity such as polycarbonates and polystyrenes in reasonable time. The present invention achieves the above-identified object by means of a polymerization process, wherein at least in the final stages of the polymerization reaction, two different types of mechanical mixing means are employed as alternatives, designated first and second mixing means. The first mixing means do generate new surfaces in the material to be treated by means of mechanical mixing and by means of gravity driven mixing, while the second mixing means do generate new surfaces in the material to be treated not by means of mechanical mixing and only by means of gravity driven mixing.

Abstract: An air compression device is applied in an air compressor, and mainly includes a first rotor, a second rotor, a stop disk, a transmission element and a drive element. When external air enters an air chamber in the air compression device, the air is rotated and compressed by the first rotor and the second rotor, and then is exhausted, the transmission element generates axial displacement vertically according to actual requirements on air admission or exhaust, and drives the drive element and the first rotor to displace, so as to change a capacity of the air chamber, and adjust the air output.
