  • Patent number: 7270024
    Abstract: A drive crank shaft and a load shaft with an eccentrically placed center shaft coupler form a mechanical torque transferring structure. Two convoluted rubber seals mounted on a center shaft coupler, a drive shaft support an a load shaft support enclose the working fluid to form double hermetic sealing. The rubber seals exert enough force against twisting to hold the center shaft coupler and prevent the center shaft coupler from rotating around its center. Two balance weights are mounted on both crank shafts symmetrically to eliminate vibration due to eccentric configuration. An enclosed housing prevents fluid from leaking into the environment. A sensor is used to detect the leakage and control the operation. This rotary shaft sealing device provides dynamically hermetic sealing by eliminating a leaking path for the pressurized working fluid.

  • Patent number: 7032584
    Abstract: A spiral mass launcher for moving a mass including a spindle support assembly; connected to a swing-arm pair module. The spindle support assembly rotates on a motor shaft, allowing the swing-arm pair module to swing on a parallel bearing shaft. A spiral track passes through a radial opening in the bearing shaft. Thus, the swinging motion of the swing-arm pair modules allows the spiral track to move in a gyrating motion. The spiral track has a first end and a second end, the first end adapted to receive a mass or projectile and a second end adapted to launch the mass. A mass can be fed into the spiral mass launcher by either a feed mechanism that feeds the mass into the first end of the spiral. Such feed mechanisms include a feed mechanism that linearly oscillates and picks up the mass at a first amplitude of oscillation and feeds the mass into the first end of the spiral track at a second amplitude of oscillation; or a feed mechanism that includes a continuous tube and “crank arm” feed.

  • Patent number: 6807878
    Abstract: A torque transmission device for providing steplessly variable torque conversion. The torque transmission device has a set of unidirectionally-rotatable, slotted levers radiating from a first axis, capable of engaging a torque output ring which is also rotatable on the first axis. An abaxial ring, which has studs that operate in the slots of the levers, is rotatable on a parallel second axis which can orbit the first axis. Torque input induces the second axis to orbit the first, and the force of orbital motion bears, through the abaxial ring, on at least one lever in a direction opposite its rotatable direction, holding it fixed, and also bears on at least one other lever in a direction that coincides with its rotatable direction, causing it to rotate. The fastest-rotating lever engages and drives the torque output ring. Varying the distance between the first and second axes varies the torque conversion ratio.

    Abstract: A wobble device is provided including a circular platform, a structure for pivoting the platform to achieve a wobbling movement, a shaft transverse to and positioned in a center of the platform, a moveable carriage rotatably attached through an arm to the shaft, a roller structure for moving the carriage on an upper surface of the platform, and a support frame below the platform. A forcing structure attached to a plurality of extension members downwardly directs the platform tilting an end of the platform toward the support frame. As the platform inclines towards the forcing structure, the carriage also begins to rotate. Once in motion, only a minimum amount of electrical energy is needed to maintain the wobble. As the carriage rotates, it turns a spur gear system attached to the center shaft. This rotational movement is then transferred through the gear mechanism to an armature of an electrical generator fastened to the platform upper surface.

  • Patent number: 4954832
    Abstract: Apparatus is provided for simultaneously rotating a plurality of parallel shafts connected, for example, to an array of rf switches that feed energy to or from an array of antenna feed horns. Each shaft is connected by a separate crank to a planar drive plate that is controllable moved relative to the switches in an orbiting fashion, to rotate the shafts in unison. The drive plate is controllably moved by a motor drive system that includes an orbiting motor secured to the plate and a base motor secured to a fixed substrate that houses the switches. The output shafts of the two motors are coupled together such that operation of either motor moves the orbiting motor, and thus the drive plate, in an orbiting motion about the base motor and substrate.

  • Patent number: 4929087
    Abstract: A method and apparatus are provided for applying multidirectional vibrations to a resilient support. The excentric of the unidirectional vibration generator cooperates with a spherical shaped member mounted for free rotation on the lower face of the vibrating table connected to the base through springs. The unidirectional vibration generator is carried by a plate parallel to the vibrating table and which is rotated about an axis X--X which is perpendicular thereto, under the action of a motor. This rotation of the unidirectional vibration generator ensures the application of multidirectional vibrations to said table.

  • Patent number: 4884465
    Abstract: A device for obtaining a directional force from a rotary motion has a frame rotating about a longtiudinal axis at a selected angular speed. A weight is connected to the frame and rotates about a transverse axis at the same angular speed. When the weight has transversed 180.degree., the frame itself will have rotated through 180.degree., so that the weight will return to its original position on the same side of the apparatus as it transversed in the first half cycle. The resultant centrifugal forces all act to one side of the apparatus, producing a unidirectional thrust.

  • Patent number: 4832586
    Abstract: In the embodiment of the invention described in the specification, a drive assembly for an eccentrically driven mass has a drive shaft which drives the mass by a first eccentric device and a secondary shaft, driven synchronously with the drive shaft, which drives a second eccentric device spaced from the first eccentric device so as to guide the mass in a constrained manner. The connection between the second eccentric device and the mass includes a resilient mounting. In order to avoid, or at least reduce, sinusoidally varying stresses imposed on the resilient mounting during operation as a result of deflection of the drive shaft, the eccentricity of the second eccentric device is larger than the eccentricity of the first eccentric device by at least a portion of the magnitude of the maximum deflection of the drive shaft in the region of the mass occurring during operation.

  • Patent number: 4795323
    Abstract: The diameter of an orbiting scroll plate is increased and the periphery of the plate is notched or scalloped to clear the bolt bosses or spacers located between the fixed scroll and crankcase. The bolt bosses act as guides for the notches in the orbiting scroll plate to thereby create an anti-rotation mechanism. Because the anti-rotation structure is on the periphery of the plate, a greater thrust surface is available.

  • Patent number: 4757722
    Abstract: A mechanism is disclosed for transforming reciprocating/rotating motion in which the reciprocating member is continuously rotated unidirectionally so as to perform 360 degrees of rotation over the course of each cycle of reciprocity, into any number of simultaneous arcuate motions intersecting at predetermined angles. This mechanism comprises a ball rotatably mounted by a supporting element and centered on a line which is perpendicular to the path of excursion of the reciprocating member at the midpoint of the excursion, which line coincides with the axis of rotation of the reciprocating member at the midpoint position, and a linkage(s) provided to transfer the motions of the reciprocating/rotating member(s) to the ball. Points on the surface of the ball are thereby made to exhibit an infinite number of arcs which intersect a common point at an infinite number of angles.
