An overfill prevention valve cooperative with a standpipe includes a plug, float, and seat that do not exceed the standpipe in diameter. The valve and standpipe can be inserted into a liquid holding tank from below. Rising liquid lifts the float and plug until the plug is sealed against the seat. The float can be above the seat and connected to the plug by a rod penetrating centrally through the seat. A check valve can enable draining of the holding tank when the liquid is withdrawn from the standpipe. The holding tank can be a fuel tank of a liquid fuel burning torch. A central reservoir system can automatically fill a plurality of holding tanks having the disclosed valves installed therein and connected in series by a plumbing system. Filling can be automatically terminated when a backpressure within the plumbing system exceeds a specified threshold.

A dispenser having a pedal actuator. The dispenser includes a valve operatively connected to a nozzle and which moves from a closed position to an open position to dispense an item, a first actuator operatively connected to the nozzle, and a second actuator located below the first actuator and operatively connected to the nozzle. The dispenser can be electro-mechanical and can include components capable of retrofitting onto existing dispensers.

In various implementations, an electronic actuator may be coupled to a valve to provide the ability to shut off anhydrous ammonia flow through the valve (e.g., in emergencies). The valve may be coupled to anhydrous ammonia tanks, such as nurse tanks and/or storage tanks. The electronic actuator may include a handle and a bracket. The handle and the bracket may include at least two attractive components that are magnetically attracted to each other upon application of an electric current and the valve may be open. When the electric current is cut, the attractive components of the handle and the bracket may not be magnetically attracted to each other and the valve may be shut off. A controller (e.g., a switch) may be coupled to the electronic actuator to allow control of the electric signal to the electronic actuator.

The specification discloses a watercraft drain plug system that includes two or more drain plugs, an actuator, and a cable assembly interconnecting the drain plugs and the actuator. The actuator may be operated to move the drain plugs between open and closed positions. The actuator includes a locking mechanism for securing the actuator in the closed position to prevent inadvertent opening of the drain plugs.

The invention relates to a wastegate actuator mechanism comprising an elongated link plate and a pin which are rotatable relative to each other. The wastegate actuator mechanism further comprises a sliding assembly including a bushing fixedly connected to the link plate and a sleeve fixedly connected to the pin. Assembly of the wastegate actuator mechanism involves pressing the bushing into the eye of the link plate and allowing material of the link plate to deform and to be received in recessed portions of the bushing in the process and/or arranging the sleeve on the pin and allowing material of the pin to deform and to be received in recessed portions of the sleeve in a process of forming an end section of enlarged diameter on the pin.

A valve operating machine includes a base having a housing thereon. A motor, and a planetary gearbox are mounted within cavities in the housing. A motor gear, a planetary input gear and an idler gear are mounted within a separate cavity. The motor gear is mounted for rotation with a motor shaft of the motor and the planetary input gear is mounted for rotation with a planetary gear spindle of the planetary input gear. The idler gear is engaged with the motor and planetary input gears. An output socket is connected to the planetary gearbox for connection to a key that is used to exercise a valve.
