  • Patent number: 4047729
    Abstract: A dirigible vehicle which is supported upon at least three ground engaging wheels located about the lower periphery of the device. Two of the three wheels are steerable while the third is fixed in position with its axis perpendicular to a line interconnecting the two steerable wheels. By manipulation of the steerable wheels, the vehicle may be adapted for movement along a linear path or may be made to spin about its own axis. Intermediate positioning of the steerable wheels will cause the vehicle to sweep in large circular arcs. The device may be self-propelled by a foot pedal assembly or by a small motor, with either a single steering wheel or dual independent steering controls. The unique steering capabilities of the vehicle make it ideally suited for recreational purposes or wherever extreme maneuverability is required.

  • Patent number: 4042252
    Abstract: An inflatable spherical device is disclosed made of two hemispherical shells or sections that are fastened together by a quick disengageable means, such as a zipper. Each hemispherical shell is made of an outer flexible skin and an inner flexible skin, concentrically spaced apart and having an annular circular flat member bonded by its outer periphery to the periphery of the outer skin and by its inner periphery to the periphery of the inner skin, forming a hemispherical air-tight compartment. Means are provided to inflate each shell. To maintain the outer and inner skins evenly spaced apart and to provide ventilation through the shells, a plurality of flexible wall tubes are disposed between the outer and inner skins. The respective ends of the tubes are bonded to suitable apertures in each of the outer and inner skins.

  • Patent number: 4039040
    Abstract: A storage assembly in which a row of storage units, such as racks, are movable between fixed limits along the length of the row in either of two opposite directions so that a gangway can be provided between the sides of any two adjacent units, and in which each storage unit is provided with a set of reversible electric motors adapted to drive individual independently rotatable drive wheels to move that storage unit, and a set of switches is provided along each side of each storage unit so as to be operated by means at the side of an adjacent storage unit, each switch in each set being associated with a respective reversible motor in the vicinity of the switch so as to control operation of that motor independently of the others and to cut-off the supply of electricity to the motor when it is operated. Thus each motor will continue to operate to move the part of the unit by which it is carried until that part reaches a datum position defined by the side of an adjacent storage unit.

  • Patent number: 4020913
    Abstract: In a draft implement having an input power driveline and a tongue adapted to be articulately connected to a tractor, an arm is pivotally mounted on the tongue and supports the driveline rearwardly of a forward telescoping assembly of the driveline which includes forward and rear universal joints. Centering tension springs extending along the tongue and interconnecting the pivotal arm and the tongue maintain the arm in a centered position in which the rear universal joint is positioned the same distance rearwardly of the tractor/implement articulate connection point as that at which the forward universal joint is positioned forwardly of the connection point. The springs will yield to allow the arm to pivot laterally to either side of the tongue to accommodate bottoming out of the telescoping assembly during sharp turns of the tractor relative to the implement. Once the tractor is re-articulated out of the sharp turn relative to the implement, the springs return the arm to its centered position.

  • Patent number: 4004648
    Abstract: An electronic governor for controlling the speed of one of two coupled prime movers wherein signals corresponding to wheel speeds of each of the two prime movers are compared to produce an error signal for controlling an actuator on one prime mover. The speed of the controlled prime mover may be abruptly reduced where the error signal exceeds a pre-determined threshold value. Monitoring means generally comprise digital circuitry, while control of the actuator is primarily analog acting through a servo loop containing a throttle position sensing device on the master prime mover, the error signal generating device and a throttle control device for the controlled prime mover.

  • Patent number: 3961810
    Abstract: Wheel for bicycle is mounted upon a wheel-mounting structure which is rigidly attached to the bicycle frame. The wheel is positioned so that, when the bicycle tilts backward to a semi-stable position on its rear wheel, the bicycle safety and conversion wheel of this invention prevents excessive further tiltback. Furthermore, the structure has a step above the wheel so that the bicycle may be ridden in an unconventional manner upon its rear wheel and its conversion wheel.

  • Patent number: 3952827
    Abstract: An improved acceleration control system is utilized to prevent overspeeding or spinning of engine driven vehicle wheels. The acceleration control system includes a first sensor for detecting variations in the rate of rotation of engine driven wheels and a second sensor for detecting variations in the rate of rotation of nondriven wheels. The two rates of rotation are compared and if the rate of rotation of the driven wheels exceeds the rate of rotation of the nondriven wheels by more than a predetermined amount, a mechanical-hydraulic throttle motion divertor assembly is activated to reduce engine operating speed. The divertor assembly includes a pair of pistons which cooperate with a body of liquid to transmit motion from an accelerator pedal to a throttle linkage. During normal operation of the vehicle, the volume of the body of liquid remains substantially constant and the body of liquid is effective to transmit hydrostatic pressure forces between the two pistons.
