Abstract: A pin spanner tool for use with a driver having a center of rotation, the pin spanner having a driven arm, a floating arm, and a bolt connecting the driven arm and the floating arm, where the bolt has a center of rotation which is co-centric with the center of rotation of the driver.

Abstract: A volatile liquid refueling apparatus, which includes a probe, and a receiver including a dual locking mechanism whereby said apparatus can be locked in either an open position or a closed position, and a safety lock which disables or enables access to the dual locking mechanism when manually.

Abstract: A method for transferring volatile liquid from a refueling tank to the fuel tank of an internal combustion device including the steps of providing a volatile liquid refueling apparatus, having a probe including an outer collar and a receiver including a receiving collar, where the outer collar and the receiving collar are configured to join to create a vapor-tight enclosure, installing the receiver in the fuel tank of an internal combustion device, installing the probe in the refueling tank, inserting the probe into the receiver, engaging the receiving collar and the probe outer collar to create a vapor-tight enclosure, transferring volatile liquid from the refueling tank to the fuel tank, and disengaging the probe from the receiver, including sealing the refueling tank and the tank.

Abstract: A volatile liquid refueling apparatus, which includes a probe including an outer collar, and a receiver including a receiving collar, where the outer collar of the probe and the receiving collar of the receiver are configured to join to create a vapor-tight enclosure, and where the receiver further includes a dual locking mechanism whereby the apparatus can be locked in either an open position or a closed position.

Abstract: A fork seal driver tool includes two half-cylindrical pieces and a rotating retaining ring which rotates to hold the half-cylindrical pieces together.

Abstract: A variable rate throttle for controlling a vehicle carburetor having control cables. The variable rate throttle includes a housing surrounding a cavity, a plurality of interchangeable throttle reels, each throttle reel having a different track radius, where a particular one of the throttle reels is positioned at a time in the cavity of the housing and which engages the control cables. A throttle handle engages the interchangeable throttle reel so that rotation of the handle causes rotation of the throttle reel and thus moves the control cables of the vehicle carburetor.
