  • Patent number: 5937698
    Abstract: A centrifugal force propulsion device includes an eccentric rotor rotatably mounted to a base via a shaft. The rotor has an aperture therein which is substantially larger than the shaft, such that the rotor is able to rotate at speed away from the shaft, as well as move longitudinally perpendicular to the axis of rotation. A drive motor drives the rotor through a stretchable flexible belt. As centrifugal force rotates the rotor toward a longitudinal standing position alone away from the shaft and drive motor, and as the drive belt is stretched, the increased tension therein pulls the drive motor and base ahead following the rotor, thus pulling the device in a desired direction.

  • Patent number: 5782134
    Abstract: A propulsion unit which converts electricity into unidirectional thrust by electromagnetically spinning an assembly of weights about a circuitous path, such that the radius of rotation for a given weight from the center of the spinning assembly is significantly greater along one portion of path than a second portion of the path. Two identical electromagnetically spinning weight assemblies spin in opposite directions to counteract torque stresses created by varying the respect radii of rotation for the weights. The resulting imbalances of centrifugal force produced by the actions of the two electromagnet weight spinning systems produces a unidirectional thrust whose vector would depend upon that sector of the path where the respective radius of rotation is greatest. A plurality of these systems arranged in counter-rotating coplanar pairs along the three axes of three dimensional space (i.e. X,Y, and Z axes) are utilized to produce a smooth unidirectional thrust along any vector.

  • Patent number: 5692411
    Abstract: The current invention discloses methods and apparatus for quieter sorters. The quieter sorter reduces the collision noises generated by movable pins of the sorter trays and a Geneva wheel which controls the movement of the sorter trays. The movable pins generally receive a force, and the force is necessary to advance the trays in a predetermined direction. As a particular pin approaches the Geneva wheel, a collision protector isolates this approaching movable pin from the force. When the Geneva wheel engages the isolated movable pin, since the isolated pin is free from the force, the isolated pin does not collide onto the Geneva wheel. This smooth engagement of the Geneva wheel substantially reduces the noise level associated with the travel of the movable pins.

  • Patent number: 5685196
    Abstract: Devices herein described utilize vehicles that are propelled, braked, and steered by means of a process called Inertial Propulsion Plus. This consists of a "power phase" to extend the weight(s) from the vehicle, alternated with a "null phase" to cancel out the return phase or stroke reactions. This process is made workable by selectively applying a pure external force derived from the pathway and opposing the movement of the weight(s) on the power phase. For non-travel-related applications, the inherent displacement can be harnessed by a treadmill or other ways for a power source to increase available power and reduce pollution.

    Abstract: A driven gear (3a), a gear (11a) to a rotary solenoid (15a) and an output drive gear (19a) are mounted to rotate together, preferably as one part turning on a stationary shaft (7a). The driven gear and the output drive gear have disengagement sectors (5a and 20a). Activation of the solenoid turns the driven gear into engagement with a normally turning drive gear (1a). Shortly after the sector on the output gear is cleared, and the load (27) is driven through engagement with driven gear (23a). After one cycle, the detent force of the solenoid positions the sector 5a so that engagement is terminated. Because the rotary solenoid need only move the gears 3a, 11a and 19a, the size of the load is immaterial to the physical requirements for the solenoid and its reliability of operation.

    Abstract: A gear combination is disclosed in which a spherical body has a plurality of grooves defined therein into which a pin gear enmeshes. Substantially all the pins on the pin gear engage the grooves in the spherical body at all times. The spherical body rotates about a first axis and the pin gear rotates about a second axis. The grooves are cut into the spherical body by a computer-controlled milling machine. The groove is endless or eventually returns to its beginning position. The axis of the milling tool may be oriented at any angle with respect to the axis of the lathe head, since the resulting motion of the milling tool necessarily cuts whatever lissajous shape is dictated by the relative periodic motions of the lathe head and milling table. The pins in the pin gear thus follow the grooves defined in the spherical body so that the rotation of the pin gear relative to the spherical body mimics the relative motions of the lathe head and milling table when the spherical body was cut.

  • Patent number: 5488877
    Abstract: Two phases of weight or mass of equal value are interconnected at a fixed distance which rotate and interact with a force retainer having a circular path. Both phases move equally but in opposite direction from the center of rotation on a guide. The guide is connected at its linear mid point to a shaft that is supported in rotation by sleeves or bearings that are firmly attached to a frame. The force retainer is also attached to the frame. The combination allows the shaft to be rotated at a frequency that causes a centrifugal force to act upon the phases. The phases interact with the circular path through rollers forcing the phase radius to change from a normal orbit of equal radius. This causes an imbalance of centrifugal forces acting on the phases. The difference between the two centrifugal forces is transmitted to the frame through the phase rollers interacting with the circular path of the force retainer. The magnitude of centrifugal force of the phases are dependent upon frequency.

  • Patent number: 5269233
    Abstract: A heater for burning particulate combustible fuel material, and a stoker for transferring the fuel for use in connection with such a heater. The heater includes a burner with a step upward from the stoker onto the burner, for reducing the possibility of the fire burning back into the supply of fuel. The stoker includes a first conveyor and a second conveyor, spaced vertically apart and connected together by a drop box. A drive arrangement for driving the conveyors includes a prime mover connected to the first conveyor by means of a drive shaft and to the second conveyor by an intermittent drive. The intermittent drive includes a second shaft with a plurality of paddles extending radially outwardly therefrom. In one embodiment, one or more paddles are removably affixed to the first shaft and extend radially outward therefrom. Thus rotation of the first shaft causes rotation of the second shaft only when the paddles are in contact.

  • Patent number: 5197354
    Abstract: An intermittent drive mechanism is provided for intermittently driving an output shaft with an input shaft that has an axis that intersects the axis of the output shaft at an angle. A driving element on the input shaft couples with a driven element on the output shaft through pairs of corresponding accelerating and decelerating pin and slot combinations which engage each other intermittently at the surface of an imaginary sphere which is centered at the intersection point of the shafts. Embodiments are provided both with and without intermittent driving gears on the elements to maintain the output shaft rotation at constant maximum velocity through a predetermined arc. The slots are curved, preferably in circular arcs, so as to optimize acceleration and the rate of change of acceleration (jerk), particularly as the output shaft approaches and leaves the point of maximum angular velocity.

  • Patent number: 5182958
    Abstract: A non-linear propulsion and energy conversion system, in one embodiment, includes an impulse drive having a frame with inner and outer pairs of driving members movable relative to the frame. Guides in the form of rails are provided for supporting the driving members so that they move along a path confined by the rails when kinetic energy is provided thereto. Solenoid switches are located at each end of the frame and are operable to cause the outer driving members to move linearly along the rails in opposite directions towards each other. At least one of the inner members has a pair of rotatable discs mounted thereon which rotate upon interaction with one of the outer members. The other inner member interacts with the other outer member in a manner so that it transmutes a greater portion of the translational kinetic energy and linear momentum applied thereto by the outer member into linear motion.
