Abstract: A vacuum pump for use with a siphon system to continuously purge gases that accumulate in a high point of the siphon system, or for priming the inlet to a pump, or to create vacuum for another purpose. Siphon systems require regular purging of gases when operating for long periods of time. The vacuum pump provides a mechanism that operates in a cycling manner. A first stage of the cycle involves filling a chamber using a pressurised liquid supply, and purging all gases from the chamber. A second stage involves isolating the chamber from the surrounding environment, and then allowing the liquid in the chamber to drain into the siphon system, while at the same time gases from within the siphon system are allowed to enter the chamber. Once the liquid has drained from the chamber, the chamber is isolated from the siphon system, and the liquid filling stage is repeated. Continual cycling of this process can purge the siphon system of gases, or be used to produce a vacuum for other purposes.

Abstract: A fluid level sensor assembly includes a first pipe component defining a flow path for the fluid and configured to be attached to a valve to control flow of the fluid from the first pipe component, and a fluid level sensor arranged in or on the first pipe component to detect a level of fluid in the first pipe component and to generate a command signal for operation of the valve according to the level detected. The assembly also includes an insert fitted to an end of the first pipe component and extending axially from the end to be fitted to an inlet of the valve, in use, wherein the insert is configured to secure the first pipe component against rotation relative to the valve inlet when the insert is fitted to the inlet.

Abstract: A method and apparatus are provided for controlling a fuel delivery system to limit acidic corrosion. An exemplary control system includes a controller, at least one monitor, an output, and a remediation system. The monitor of the control system may collect and analyze data indicative of a corrosive environment in the fuel delivery system. The output of the control system may automatically warn an operator of the fueling station of the corrosive environment so that the operator can take preventative or corrective action. The remediation system of the control system may take at least one corrective action to remediate the corrosive environment in the fuel delivery system. One or more sensors may be employed to signal proper operation of the remediation system.

Abstract: The present invention is directed broadly to a tank overfill protection system (10) generally comprising a flow control valve (12) operatively coupled to a tank level sensor via a pilot line (16). The flow control valve (12) generally comprises: 1. a valve body (26) defining a fluid passageway (28) between a fluid inlet (30) and a fluid outlet (32); 2. a piston (34) slidably mounted within the fluid passageway (28) and arranged for displacement for opening and closure of the fluid outlet (32); 3. a bleed fluid cavity (36) located within the valve body (26) and arranged to cooperate with the piston (34); 4. a bleed fluid conduit (38) operatively coupled to the bleed fluid cavity (36); 5. a venturi arrangement (40) operatively coupled to the bleed fluid conduit (38) to promote evacuation of bleed fluid from the bleed fluid cavity (36) thereby opening the fluid outlet (32) by displacement of the piston (34).

Abstract: A lubricant reservoir system includes a lubricant reservoir having an interior wall and an inlet for receiving lubricant from a supply. A follower device in the reservoir contacts the interior wall of the reservoir in a sliding and sealing manner, and the follower device is movable up and down in the reservoir from a first position to a second position in response to a changing lubricant level. A valve is in fluid communication with the inlet and is configured to selectively prevent a flow of the lubricant through the inlet. A connector operatively connects the follower device to the valve unit such that the flow of the lubricant through the inlet is prevented when the follower device is in the second position. The connector is configured such that the valve is positionable independently of the reservoir.

Abstract: A system includes a first jacket that contains seawater and a first tank storing a first fluid under pressure. A second jacket contains seawater and a second tank storing a second fluid under pressure. An actuator cylinder defines a space that receives the fluids from the first and second tanks. The actuator cylinder includes an actuator piston that divides the space into a first volume for the first fluid and a second volume for the second fluid. A hydraulic cylinder includes a hydraulic piston configured to move and change an amount of hydraulic fluid in the hydraulic cylinder, wherein the hydraulic piston is fixedly coupled to the actuator piston. A buoyancy plug changes a position in connection with the amount of the hydraulic fluid in the hydraulic cylinder, wherein the position of the buoyancy plug affects a buoyancy of a vehicle.

Abstract: An autofill shutoff valve includes a valve body mounted to a lubricant reservoir and secured to a fill tube extending into the reservoir. The autofill shutoff valve has a valve stem extending through the valve body and into the lubricant reservoir. The valve stem is actuated by a plate disposed within the reservoir from a first position, wherein lubricant flows from a lubricant inlet to a lubricant outlet through the valve body, to a second position, wherein the valve stem blocks the flow of lubricant through the valve body. The autofill shutoff valve provides lubricant directly to the reservoir, thereby eliminating external plumbing and the autofill shutoff valve also prevents overfill of the reservoir by cutting off the flow when the reservoir is full.

Abstract: A vent valve for an actuator disposed in a lubricant reservoir includes a bore extending through the plate, a seal disposed within the bore proximate a top surface of the plate, a retaining member extending about a lower opening of the bore, and a ball disposed within the bore between the seal and the retaining member. The vent valve is configured to allow air to pass from a lower portion of a lubricant reservoir as lubricant fills the lower portion. The vent valve also allows air to pass to the lower portion of the lubricant reservoir as lubricant is dispensed from the reservoir. The vent valve closes when the lubricant level reaches the vent valve, thereby preventing lubricant from flowing through the vent valve. The sealed vent valve allows the actuator to rise in response to a rising lubricant level.

Abstract: In accordance with the present invention a start/stop system is provided for a machine that drives an electric generator by moving buoyant modules on a duty-cycle pathway through a bi-level water tank. Included is a valve mechanism that maintains different water surface levels in the bi-level tank, and also establishes different spaces within the bi-level tank. Additionally, grips are included for selectively holding individual modules in respective spaces. To stop the machine, water is drained from the bi-level tank, and grips are activated, to hold modules in their respective spaces. To restart, water is introduced into the spaces and the grips are deactivated to release the modules for operation.
