Abstract: A transmission device for converting rotary motion into linear force by varying the centers about which the weights rotate comprising two impellers (off-centered weights) which rotate in opposite directions. Impellers will be mounted within a rocker element which will rock back and forth in a controlled sequence. The amplitude that the rocker element rocks will be controlled by a cam which will be directly geared to a large gear. The impellers will also be geared to the same large gear which will rotate at a controlled speed. However, the speed of the impellers will be constantly changing. As the rocker element rocks in the same direction as the large gear the speed of the impellers will decrease and increase when the rocker element rocks in the opposite direction of the large gear. A clutch device will connect the large gear to a second large gear which will be equipped with a large flywheel and provided with a source of power.

Abstract: A centripedal force concentrator having a main rotating shaft with one or more arms extending perpendicularly from the central main shaft. Rotating gears having extending weighted armlets are attached at the far end of the arms. Secondary shafts are disposed between a surrounding geared collar and the rotating gears, such that when the central shaft is rotated the rotating gears are turned by the secondary shafts. The rotating weighted armlets cause variations in the centripedal force giving a net resultant force. Pairing synchronized devices can eliminate cross torque of a single device.

Abstract: A gearing has on its driving shaft a drive means carrier member carrying drive means in the form of pins protruding towards a driven means carrier member fixed to the driven shaft and carrying divergently arranged driven means. The driven shaft is offset relative to the driving shaft so that the circular orbital path of movement of the driven means surrounds the circular orbital path of movement of the driven means. From the drive means always only one single drive means contacts a driven means and only in a portion of the orbital path thereof which portion is more remote from the axis of the driven shaft than that portion of this orbital path arranged nearer to the driven shaft. In the other portions of their orbital path, the drive means pass within the orbital path of the driven means but do not contact these. This results in an increased torque of the driven shaft.

Abstract: Disclosed is a device for producing a unidirectional force which may be used to propel a vehicle or other body in one direction or to serve in other applications requiring such a force. The device uses a centrifugal force generator which repetitively provides alternately occurring prolonged centrifugal forces of opposite direction along a line fixed relative to the generator. As these forces are produced the generator is turned relative to a supporting carriage so that each time such a force occurs it has a generally forward direction relative to the carriage. Two or more centrifugal force generators may be mounted on a single carriage and operated in synchronism and in proper phase relationship to one another to produce a forwardly directed force of relatively steady magnitude and/or to cancel force components directed perpendicular to the forward direction.

Abstract: In computerized tomographic apparatus having an intermittent rotational motion the scanning time can be reduced by increasing the rotation speed.

The invention reduces that problem by balancing the forces of rotation at least in part by appropriately placed counter masses. In one embodiment the counter masses rotate and properly balance the forces. In another embodiment they move linearly and delay the application of the forces to the mainframe and transmit the delayed forces over a longer period.
