摘要:
Discharging device for an extrusion press, including a frame being movable in the axial direction of the press; a first part being connected to the frame and adjustable in height, the first part including a substantially flat plate and cutting means; a second part being movable relative to the frame and being adjustable in height, the second part including a horizontally disposed axle, a conveyor belt being suspended from the axle and tiltable about the axis of the press, and a coupling for the conveyor belt; a coupling rod for the cutting means being engageable with the coupling for periodically connecting the cutting means to the conveyor belt; and a continuously variable drive driving the conveyor belt.
摘要:
System for supplying current to a group of high-current resistance furnaces including a plurality of transformers switchingly connectible sequentially to the individual furnaces singly and together in parallel, the group of furnaces being subdivided into two subgroups of furnaces, each having one of said transformers associated therewith, and including a third transformer selectively switchingly connectible in parallel to the one and the other of the two subgroups of furnaces.
摘要:
To minimize the amplitude and spectrum of side bands, beats and harmonics created by changing a transmitter power level between bursts in a GSM TDMA cellular radio communications system, the present invention does not comply with the GSM recommendations by avoiding ramping down to zero power level between time slots. Rather, the transmitter power is ramped between the power value of a previous burst and that of a subsequent burst. In this way, the magnitude or slope of the ramp is minimized and the full time between bursts is available to make power adjustments. A number of embodiments are disclosed.
