    Abstract: Improvements in A wind generator, that may also be called and relates to, windmill, turbine or aero generator, on a vertical axis. The vertical axis gives the windmill the ability to be turned by air, or liquid if inverted, from any direction parallel to the earth's surface. Multiple blades rotate through a horizontal axis into the wind to lessen air resistance on one side while turning vertically on the other side to gain energy from the wind. The system is counter-weighted as needed, to reduce energy loss, by different methods including but not limited to gears, levers, pneumatics, cables, hydraulics or added counter-weight. The electrical generating machinery is below the blades or at the bottom of the vertical drive shaft.

    Abstract: A new type of propeller with a transverse driving shaft can be mounted on an outboard internal combustion engine instead of a conventional screw type propeller or disposed directly on the transom of a boat. The propulsion thrust is generated by flat propeller blades mounted on planetary gearboxes and rotated simultaneously around two perpendicular intercrossed axes of rotation. Such double rotation causes the blades to move along the specific curved paths and to generate virtually permanent and effective propulsion thrust for propelling watercraft. Both sides of the propeller blades are used as working surfaces. Unlike the conventional screw type propeller, a new propeller can be disposed not only under the water but also over the water with the blades extending into the water during their rotations for propelling the boat.

During the rotation of the driving shaft, the blades extend into the water when their orientations are changed from horizontal to vertical positions. A propulsive force is developed as a result of a double rotation of the blades with the same speed around intercrossed axes of the driving shaft and radial shafts of the gear-box. During each propulsion stroke, circumferential velocities of the blades are gradually accelerated when they move downward. Both sides of the blades are used consecutively as working surfaces. Disposed with variable angles of incidence, the propelling blades work simultaneously as paddles and as blades of a screw propeller. The propulsion apparatus can also be used in typical outboard engines instead of the traditional screw propellers.

    Abstract: An improved windmill includes a conical rotor unit, a frame for supporting the conical rotor unit and a base for supporting the frame. The conical rotor unit has a conical rotor with a plurality of spaced curved blades disposed thereon and a plurality of spaced slant blades located at an outer rim of the conical rotor. The conical rotor has small wind resistance and may rotate under low speed wind to generate rotor rotation. The frame is rotationable about the base to enable the conical rotor to capture wind from different directions. The conical rotor is heavier than conventional windmill rotor and may serve as a fly wheel to store kinetic energy for the windmill to produce steady rotation under different wind speed for a long period of time.

  • Patent number: 6109875
    Abstract: A cycloidal propeller including a so-called slider-crank mechanism. The couplers of the slider-crank mechanism are attached to a control ring which is attached to a ball socket located at the lower end of a control rod. The required torsional retention relative to the rotor housing is accomplished by a dual parallel guide, which is mounted by revolute joint connections to the control ring on one side and by revolute joint connections to the rotor housing on the other side.

  • Patent number: 6015262
    Abstract: A fan apparatus includes a housing with front and rear parts and two swivel joints, a driving motor disposed in the housing, inner and outer annular members, a transmission member, and an anchoring member. The motor has a rear portion provided with a worm section extending toward the rear part. The inner annular member is sleeved on the front part and is connected to the joints so as to swivel relative to the latter. The outer annular member is sleeved retainingly on the inner annular member and is angularly adjustable relative to the same. A swing rod has a first proximate end relative to the worm section and mounted pivotally on the rear part, and a first distal end which extends toward the front part. The transmission member is disposed in the rear part to transmit an axial rotation of the worm section to swing the first distal end of the swing rod relative to the first proximate end in a plane parallel to the worm section.

  • Patent number: 5469718
    Abstract: A debris cleaning apparatus for a circular knitting machine includes a horizontal radial support arm rotatably mounted coaxially to the machine frame with a rotary paddle-type fan mounted to one outward end of the support arm for movement within a circular range of motion and a counterweight mounted to the other outward end of the support arm. A drive motor imparts circular motion to the fan either in a vertical plane or in a conical path of motion, wherein the line of force of the fan is substantially maintained out of co-planar relation with the central axis of the machine. In this manner, the moving airstream generated by the fan provides a motive force for propelling the support arm to rotate about the central axis at a cyclically varying speed of rotation, either reversingly or in a single rotational direction. Thus, the airstream is directed through its range of movement over the knitting and yarn feeding instrumentalities of the machine about its full circumferential extent to blow lint from surfaces.

  • Patent number: 5411372
    Abstract: Disclosed is a new pole mounted revolving air circulating fan for inducing air movement within an air mass by use of a rotating impeller which simultaneously revolves around a vertical axis. The pole mounted revolving air circulating fan comprises a telescoping support pole extending substantially vertically upwardly from a mounting floor surface to a mounting ceiling surface, the ends of the support pole frictionally engaging the mounting surfaces. A fan, comprising a rotary air impeller coupled to an electric motor through a drive shaft, is revolvedly mounted on the vertical support pole. A generally cylindrical motor housing encloses the motor and the motor power supply leads. A blade guard, constructed of wire rods forming a substantially annularly shaped wire cage, encloses the impeller to prevent injury from contact therewith. The guard has a central hole through the back wherethrough the front end of the motor housing extends.

  • Patent number: 4703152
    Abstract: A portable electric heater/fan which can oscillate from side to side over a distance of 45 degrees or 90 degrees or remain stationary and which can also be tilted backward or forward so as to provide a beam of hot or cold air whose lateral extent and direction can be adjusted over two mutually perpendicular axes includes a compartment containing a heater/fan assembly and being slidably mounted for back and forth tilting movement on a neck joint fixed to a main gear carried by a shaft mounted for rotation about a vertical axis on a base. The main gear is coupled by a drive gear to the shaft of a synchronous electric motor mounted on the base. A first and a second set of cooperable limit stops are provided on the base and main gear for limiting the rotation of the main gear by the motor to either 90 degrees for the first set or 45 degrees for the second set.
