摘要： A screw centrifuge for the continuous separation of flowable substances of different densities includes a rotor drum having discharge openings for the heavy phase that are arranged in a conical portion of the rotor wall, and weir openings for the light phase that are provided on an end wall of the rotor drum. A conveyor screw is rotatable inside the rotor drum and has a screw blade mounted on a hollow shaft for transporting the heavy phase to the discharge openings. A mixture inflow tube is arranged coaxially inside the hollow shaft and leads to a feed chamber in the hollow shaft that is in flow communication with the screw blade. An air extraction member is provided before the feed chamber and generates, in the annular space enclosing the inflow tube, a suction flow co-directional with the delivery direction in the inflow tube.

摘要： Some embodiments relate to a phase shifter that includes an I/Q phase shifter and at least one LC balun. Compared to conventional phase shifters, phase shifter has primarily only LC components, thereby limiting losses relative to conventional solutions. In one embodiment, for example, a phase shifter shows a large bandwidth at 77 GHz center frequency (e.g., 1 dB amplitude error bandwidth is approximately 40 GHz; 1° phase error bandwidth is about 16.5 GHz). The inductors included in phase shifter, in contrast to the quarter wave transmission lines used in conventional phase shifters, reduces chip area compared with conventional solutions. In some embodiments, an emitter follower helps to provide a relatively constant output that is largely independent of temperature, input power, VCC, manufacturing variation, and so on.
