Abstract: A stepless variable ratio gear train (201) comprising first and second stage gear trains (1), (101) with controllable variable velocity ratios between their inputs and outputs, wherein the velocity of the output of the first stage gear train (1) relative to the input of the first stage gear train (1) is decreased when a relatively high torque is applied to the gear train (201), and is increased when a relatively low torque is applied to the gear train (201). The gear train (201) further comprising means to control the velocity ratio of the first stage gear train (1) comprising a brake (301) that produces a relatively high braking force when a relatively low torque is applied to it to produce a low velocity ratio in the first stage and second stage gear trains (1), (101) and a relatively low braking force when a relatively high torque is applied to it to produce a high velocity ratio in the first stage and second stage gear trains (1), (101).

Abstract: A method and assembly of replacing a receptacle seal is provided. A seal removal kit includes a poppet depressing member, retaining collar, seal removing tool, and a seal insertion sleeve that allows the seal to be replaced without removal of the receptacle or portions thereof from a vehicle.

Abstract: A dry break disconnect and process provides a frangible connection in the fuel line to prevent damage in case of a drive away event. Frangible connecters such as rivets are intended to shear at a predetermined force to separate upstream and downstream body portions of the disconnect assembly and thereby actuate upstream and downstream poppet members to seal and prevent further spillage of fuel.

Abstract: An inwardly opening mechanical vent system is provided for use in a fluid tank having a bottom loading valve and a vent formed in an upper tank surface. The vent system includes a spring interposed between a vent valve and a body extending downwardly into the tank to bias the vent valve upwardly into a closed position. A shaft extends downwardly from the vent valve and is connected to a lever mechanism. The lever mechanism includes a scissor-hinge assembly connected to a trunnion of the body. A linkage rod extends upwardly from the bottom loading valve and is capable of actuating the lever mechanism to lower the shaft and vent valve into the tank to open the vent when the bottom loading valve is opened.
