Abstract: A fuel enhancement method and system for supplying the engine with a pressurized fuel mixture comprising a mixture of the liquid fuel and the gaseous component including provisions to maintain the ratio of gas to liquid in the mixture at a predetermined value and maintain the pressure of the fuel mixture applied to the engine at a predetermined value. A system using variable speed drive pumps is disclosed.

Abstract: A shock absorbing bicycle wheel hub apparatus uses an open ended, cylindrical shock absorber housing mounted concentrically within a wheel hub. The wheel hub is adapted for rotation about the shock absorber housing. A pivot tube is axially aligned with the shock absorber housing and rotationally mounted within its sidewall. Terminal ends of the pivot rod engage cover plates fixedly mounted thereon. A pressure tube is axially aligned with the shock absorber housing and extends through it so that its terminal ends may be fixed in the cover plates. A shock-absorbing medium is compressively positioned between the pressure tube and an interior surface of the shock absorber housing. The cover plates engage a bicycle fork so that weight supported by the bicycle fork is transmitted through the cover plates and the pivot tube and pressure tube, to the shock absorbing medium, and thereby, through the shock absorber housing and the wheel hub to a wheel of the bicycle.

Abstract: An outer wheel, tire and rim, is mounted onto an inner wheel or hub and is adapted for low friction rotation on the hub. An arm is pivotally attached to the inner wheel and carries a receiver for the axle upon which the wheel is mounted so that the axle is positionable over an arc of rotation about the pivot point of the arm. The arm is biased by an elastomeric body so that as the arm moves over its arc of rotation, the elastomeric body is compressed. As the wheel rotates under load, road shocks are transferred to the biasing device which acts as a shock absorber.
