No. 13/199,849 ?led Sep. 9, 2011 Title of Invention Angular Momentum Engine. BACKGROUND [0026] From the perspective of Man ‘A’ on the train, he is moving east at a constant speed of 3 feet per second in the opposite direction the train is moving and stationary relative to Man ‘B’ standing at rest, motionless on the train platform. [0027] From the perspective of Man ‘B’ on the train plat form, Man ‘A’ on the train is stationary relative to him, and the train is moving at a constant speed of 3 feet per second to the west. [0028] In this patent design, the ‘planetary gearbox’ and ‘point mass’ are accelerated to a constant relative rotational [0002] State of the art Motion Control System and equip ment are used in controlling the Angular Momentum and positioning of a ‘point mass’ rotating horizontally around a vertical axis to change the rotating ‘center seeking’ centrip etal force to a linear ‘center seeking’ centripetal force. FIG. 6 [0003] This invention uses this linear ‘center seeking’ cen tripetal force to accelerate a vehicle such as a commercial automobile. The design is new relative to how the forces are created and used but the technology has been solidly embraced in the laws of physics for many decades. [0004] While it is common place for an engine to create a force to push a vehicle, or an equal and opposite reaction to propel an aircraft, this linear ‘center seeking’ force pulls the vehicle. Such changes to normal are exhibited throughout the speci?cations and therefore requires a perspective relative to a changing environment. velocity counter-clockwise. The ‘point mass’ is then acceler ated to the same constant relative rotational velocity but in the opposite direction of the gearbox, clockwise. FIG. 1 FIG. 2 [0029] From the perspective of the ‘point mass, it is rotating clockwise at a constant speed but in the opposite direction the gearbox is rotating and stationary relative to an ‘Observer’ standing at rest, motionless. [0030] From the perspective of an ‘Observer’ the ‘point mass’ is stationary relative to him, and the gearbox is rotating at a constant speed counter-clockwise. [0031] The ‘point mass’ is now moving at the same speed counter-clockwise as it is clockwise and therefore to a sta tionary observer the point mass appears not to be moving relative to him. This positioning of the relative velocity and relative motion of the ‘point mass’ to a stationary reference point results in the ‘center seeking’ centripetal force being changed from rotational to linear.

[0033] A point mass is used in each system, ‘Point Mass 1’ in FIG. 1, ‘Point Mass 2’ in FIG. 2 to balance the rotational forces. FIG. 3 depicts an overlay of FIG. 1 and FIG. 2 illus trating the two point masses are 180 degrees apart at all times and also that the ‘point masses’ rotate in the same direction whether their motion is counter-clockwise, clockwise, or at rest relative to a stationary reference point during spin-up. [0034] Balancing the rotational forces allows the system to spin-up vibration free and also provide a neutral position after spin-up where the net linear ‘center seeking’ forces are bal anced. FIG. 5a [0035] This balancing of forces is needed during times when the vehicle is stopped, an accelerating force is not required, or when the vehicle is on a downhill incline. Pro viding full to partial power is as simple as moving the ‘point masses’ to the power position. [0036] ‘Point Mass 1’ and ‘Point Mass 2’ move a maximum of 90 degrees to apply full forward or reverse power. Mini mum power is 1 degree, maximum power requires a move ment of 90 degrees as illustrated in FIG. 5b, FIG. 50. DETAILED DESCRIPTION OF INVENTION [0037] The planetary gearbox is utilized in changing the relative velocity and relative motion of the ‘point mass’ to a stationary reference point. [0024] This invention changes rotating ‘center seeking’ The synchronous spin-up applies a counter-clockwise torque centripetal force to linear ‘center seeking’ centripetal force simply by changing the relative velocity and relative motion to the ‘planetary carrier shaft’ by Servo Motor 1 & 3 and to the of a ‘point mass’ to a stationary reference point. [0025] As an analogy Man ‘A’ sitting on a train while its leaving the train station is accelerated to a constant speed of 3 feet per second to the west. He stands up and walks at the same constant speed of 3 feet per second, but in the opposite (ring, planet, sun) of the planetary gearbox which results in direction to the east. ‘ring gear’ by Servo Motor 2 & 4 locking the internal gears the gearbox and ‘point mass’ moving at a constant relative rotational velocity counter-clockwise at —3000 rpm. FIG. 1 FIG. 2 [0038] Motor 1 & 3 rpm to the planetary carrier shaft remain the same at —3000 while Motor 2 & 4 rpm to the ring Aug. 21,2014 US 2014/0232224 A1 gear is increased synchronously from —3000 to —4000 rpm. The addition —1000 rpm to the ring gear using a 1:3 ratio speed increaser gearbox, moves the ‘point mass’ to the same of high centripetal forces generated from the product of a relative rotational velocity, but in the opposite direction of the ated from the product of a large mass at low revolutions per minute with a 50 foot radius. As indicated above the centrip etal force needed for a speci?c application are dependent on the Centripetal Force Calculator FIG. 7. gearbox, clockwise at +3000 rpm. FIG. 1 FIG. 2 [0039] The ‘point mass’ is now moving at the same speed counter-clockwise as it is clockwise and therefore to a sta tionary observer the ‘point mass’ appears not to be moving relative to him. This positioning of the relative velocity and relative motion of the ‘point mass’ to a stationary reference point results in the ‘center seeking’ centripetal force being changed from rotational to linear. [0040] The centripetal force generated is the result of its mass><velocity2/radius. The centripetal force calculation is small mass at high revolutions per minute with a 6 inch radius, FIG. 10 illustrates examples of high centripetal forces gener [0046] The Timing documentation FIG. 5a, illustrates the starting and ending timing marks for ‘Point Mass 1’ and ‘Point Mass 2’ before and after spin-up. FIG. 5b illustrates the timing marks for neutral thru full power for ‘Point Mass 1’ and ‘Point Mass 2’. during forward acceleration, FIG. Sc illustrates the timing marks for neutral thru full power for ‘Point Mass 1 ’ and ‘Point Mass 2’ during reverse acceleration. illustrated in FIG. 7 [0047] [0041] used to control the point masses movement from neutral for minimum to maximum power. A movement of 1 degree for minimum power to a maximum of 90 degrees for full power. On a ‘simple planetary gearbox’ when the planet is held and the power input is to the ring gear, power output is to the sun gear, rotational speed is increased and rotational torque is reduced. The rotational direction power output is in the opposite direction of the drive member. FIG. 4 [0042] This patent design has only one change to this simple planetary gearbox outlined in FIG. 4. In a simple planetary gearbox the carrier is held stationary at 0 rpm while in this Patent Design the carrier is held stationary at —3000 rpm in this example. FIG. 5d Increasing the rpm to the ring gear above —3000 rpm to —4000 rpm, with a 1:3 ratio speed increase gearbox, results in rotational speed being increased, rotational torque being reduced, and the rotational direction power output in the opposite direction of the drive member identical to a simple planetary gearbox as shown in. FIG. 4 FIG. 8 [0043] To a stationary observer looking at a ‘simple plan etary gearbox’ the ‘point mass’ is rotating at +3000 rpm but to a stationary observer looking at this ‘patent design gearbox’ the ‘point mass’ appears to be stationary but is also rotating at +3000 rpm. FIG. 5e [0044] FIG. 5d illustrates some examples of ‘Timing Docu mentationiRPM’ that can be utilized in this Angular An ‘electronic accelerator pedal’ or ‘joy stick’ is 1. This invention ‘Angular Momentum Engine’ changes rotating ‘center seeking’ centripetal force to linear ‘center seeking’ centripetal force. This change in force as indicated in [0035] is accomplished by changing the relative velocity and relative motion of a ‘point mass’ to a stationary reference point. The linear centripetal force generated in this ‘Angular Momentum Engine’ can vary as the centripetal force [0035] is a product of the mass times the velocity squared divided by the radius. When these forces are used in pairs [0036] the ‘point masses’ can be used to provide a neutral position where the centripetal forces are balanced and also provide minimum to full power, forward or reverse, by moving each ‘point mass’ plus or minus 1 to 90 degrees from the neutral position. The linear centripetal force [0035] can be used to power land, sea, as well as space vehicles. This design allows the variables, the point mass, point mass velocity, radius of the point mass arm, pulley ratio, and Momentum engine. gearbox ratio to be increased or decreased to ?t the This design allows the variables, the point mass, point mass velocity, radius of the point mass arm, pulley ratio, and the tion from a few pounds to millions of pounds of Cen gearbox ratio to be increased or decreased to ?t the desired centripetal force needed for a speci?c application. [0045] If you double the point mass or radius the Centrip etal force doubles. If you double the speed the Centripetal force quadruples, Forces from a few to millions of pounds of centripetal force canbe generated. FIG. 9 illustrates examples desired centripetal force needed for a speci?c applica tripetal Force. Doubling the mass or radius doubles the Centripetal force, doubling the speed quadruples the Centripetal force. This patent can optionally power a generator to create current.
