A synchronous induced wind power generation system is provided, comprised of a horizontally rotatable turbine-generator section that wind vanes into the prevailing wind direction. The turbine-generator section has a horizontally disposed turbine shaft therein, and air induction shrouds at either end thereof, the anterior areas of the air induction shrouds having larger areas than the interior area of the turbine-generator section, so as to induce a larger differential air pressure across the turbine. The turbine is directly coupled to a synchronous AC generator that is synchronized with an external power line in connection therewith, and directly generates synchronous AC power. Further, turbine magnetic brakes and/or adjustable pitch directrix blades are employed to control the speed of rotation of the turbine 1) during synchronization with the electrical line, 2) to modulate turbine power, and 3) to protect against overspeed during high wind and loss of load.

A dragon-gate processing machine having a dragon-gate support structure, at least one lateral girder coupled to the support structure for mounting tool holding members and automatic tool exchange devices, a plurality of working tables mounted below the dragon-gate support structure, driving apparatus for driving the working tables, a mechanical transmission for coupling the drive apparatus to the working tables, an auxiliary rotary arm mounted to the dragon-gate support structure for holding auxiliary processing devices, and control means for controlling operation of the dragon-gate machine. The dragon-gate machine allows processing such as drilling, lathing, and planing to be performed on a workpiece mounted on the working table. The novel allows such processing to be performed at any angle and at any desired direction according to the processing requirements of the workpiece.

The novel invention allows such processing to be performed at any angle and at any desired direction according to the processing requirements of the workpiece.
摘要:
The invention relates to an adjustable speed driving device. The motor 54 drives directly the inductor 1 of an eddy current clutch 51. The double bell 7-10 is keyed to the adjustable speed output shaft 2. The skirt 10 rotates round the stationary inductor 8 of the eddy current brake. A safety brake 53 is locked by the spring 15 when the electromagnet 12 is off. Application: one-piece device for handling a load on a crane or a travelling crane.
摘要:
A propeller alignment device is described. The propeller alignment device can include a second retainer attached to a propeller and a motor. The propeller alignment device can also include a first retainer that does not rotate, but that is aligned with the second retainer. The first retainer can include two or more magnets oppositely orientated relative to each other. The second retainer can also include two or more magnets oppositely orientated relative to each other. As the second retainer rotates relative to the first retainer, the magnets alternatingly align with each other. In the absence of a current applied to the motor, the magnets may magnetically bias the second retainer into a predetermined orientation relative to the first retainer.

The predetermined orientation can be predetermined to correspond to an alignment of the propeller that is desirable (e.g., that minimizes aerodynamic drag on the propeller).
摘要:
A stepping motor having a printed circuit rotor including a first printed circuit on one side of the rotor formed in a plurality of spiral coil windings, and a second printed circuit on the other side of the rotor formed in an equal number of like coil windings, the coil windings on one side being 90.degree. out of phase with those on the opposite side. The motor also includes a slip-ring arrangement for delivering pulsed DC power alternately to the first and second printed circuits for driving the rotor in a step-wise manner.
