Patent number: 9334151Abstract: Shielding liquid from electronic components may be accomplished by a variety of systems, devices, and techniques. A shielding device may include a substantially vertical channel mounted to a fuel dispenser component; an airflow inlet; a plurality of arrays of angled protrusions; and a plurality of substantially vertical protrusions. The channel is adapted to guide an airflow. The plurality of arrays of angled protrusions are, disposed within the channel and are substantially parallel in arrangement within each array. The angled protrusions within each array are angularly offset in arrangement relative to the angled protrusions within adjacent arrays. The arrays of angled protrusions are adapted to form a tortuous path for the airflow through the channel. The plurality of substantially vertical protrusions are disposed within the channel and are located between the airflow inlet and the plurality of arrays. The vertical protrusions are adapted to substantially straighten the airflow within the channel.Type: GrantFiled: January 17, 2014Date of Patent: May 10, 2016Assignee: Wayne Fueling Systems LLCInventors: Patrick Zuzek, Mark J.

Patent number: 8764984Abstract: A parallel flow filter-in-filter design for a filter system is provided. The filter-in-filter design provides two distinctly parallel or independent flow paths within a filter assembly in a single housing or shell. The filter assembly includes a first outer filter element radially spaced apart from a second inner filter element. A centertube and a funnel shaped passageway housed within the centertube are provided in a space between the first outer filter element and the second inner filter element. The centertube and funnel shaped passageway work in tandem to provide two distinct parallel or independent flow paths within the filter assembly. The funnel shaped passageway is provided generally below the second inner filter element within the centertube.Type: GrantFiled: April 18, 2012Date of Patent: July 1, 2014Assignee: Cummins Filtration IP, Inc.Inventors: Carey A.

Patent number: 8425772Abstract: A filtration device is provided that includes a filter component and an additive component. The filter component includes concentrically arranged filtering elements disposed in a filter-in-filter configuration. The additive component includes at least one additive material that is introduced into a working fluid to be filtered. The filter component and additive component provide an assembly for a filtration system that would filter a variety of working fluids. The filter component and additive component provides an assembly that can filter fluids more efficiently. As a result, fluids may enjoy, for example, extended drainage intervals and thereby reduce component wear.Type: GrantFiled: July 29, 2011Date of Patent: April 23, 2013Assignee: Cummins Filtration IP, Inc.Inventors: Harold R.

Patent number: 7876706Abstract: Techniques are provided for selecting a root node in an ad hoc network comprising a plurality of nodes including a first node. According to one implementation of these techniques, a first node can receive a message from at least one of the other nodes. Each message includes a number of primary factors associated with a particular node regarding capabilities of the particular node. The primary factors associated with each node can then be evaluated, and an attempt can be made to select the root node based on the primary factors associated with each node. If the first node is unable to select the root node based on the primary factors associated with each node, then the root node can be selected based on secondary factors associated with each node.Type: GrantFiled: February 28, 2006Date of Patent: January 25, 2011Assignee: Motorola, Inc.Inventors: Randy L.

Patent number: 7527739Abstract: An apparatus, system, and method are disclosed for multistage water separation. A first separation layer separates water droplets from a fuel flow by repelling the first water droplets. A coalescing layer may coalesce fine water droplets in the fuel flow. In one embodiment, a centrifugal separator directs the fuel flow tangentially to a filter wall and the centrifugal force of the fuel flow directed tangentially along the filter wall biases water droplets from the fuel flow. A second separation layer separates second water droplets from the fuel flow.Type: GrantFiled: August 15, 2005Date of Patent: May 5, 2009Assignee: Fleetguard IncInventors: Zemin Jiang, Ted S.

Patent number: 7506663Abstract: A magnetic check valve includes a cage mountable in a fluid flow duct and supporting a plunger movable between a closed position blocking fluid flow past the valve, and an open position permitting fluid flow past the valve. One of the cage and the plunger includes a magnet, and the other of the cage and the plunger includes ferrous material magnetically attracted to the magnet to magnetically bias the plunger to the closed position.Type: GrantFiled: July 20, 2006Date of Patent: March 24, 2009Assignee: Fleetguard, Inc.Inventors: Chad M.

Patent number: 7431575Abstract: A priming pump for fluid delivery arranged with a base defining a flow inlet, a flow outlet, and a control valve positioned therebetween. The priming pump includes a housing assembled to the base with an inlet flow valve positioned in an inlet valve compartment and an outlet flow valve positioned in an outlet valve compartment. The valve compartments are in communication with a plunger chamber including an axially movable plunger. A spring-biased control knob is assembled to the plunger and to the control valve for controlling its position between either a direct-flow orientation or a by-pass orientation. With the control valve in the by-pass orientation, upward movement of the control knob draws fluid into the inlet valve compartment and into the plunger chamber. The down stroke of the control knob pushes the fluid out of the plunger chamber.Type: GrantFiled: January 21, 2005Date of Patent: October 7, 2008Assignee: Cummins Filtration IP, Inc.Inventors: Charles W. Hawkins, Ricky England, Kevin C. South, Jeffrey B. Sharp, Ismail C. Bagci, Mark J. Johnson
