  • Patent number: 8555927
    Abstract: The invention is a divider block assembly suitable for use at high fluid pressures. Applicant has found that a sufficiently deep counterbored hole allows a mounting bolt to apply the sealing pressure well below the divider block surface, which can reduce or eliminate the compressive force on the metal around the piston bore, thereby reducing or eliminating distortion of the piston bore of the divider block and providing.

  • Publication number: 20120305127
    Abstract: A method and structure are described for preventing the accidental introduction of gasoline into the fuel system of a diesel-powered vehicle. In a first preferred embodiment, a gasoline fuel nozzle is configured with a magnet, such as magnetic strips, and the entrance to a fill tube of a diesel-powered is configured with a magnetic field sensor ring. When an incorrect fueling operation, such as the introduction of gasoline into the fuel tank of the diesel-powered vehicle, is attempted the sensor ring alerts the operator visually and/or audibly before fueling starts, thereby preventing incorrect fueling. In alternative embodiments, sensing of an attempted incorrect fueling operation may require only the sensor ring.

  • Patent number: 8069950
    Abstract: A device that relieves lubricant pressure in a divider block lubrication system into a fluid reservoir, a container, or directly back into the compressor frame to which the tubing is connected. This eliminates housekeeping, environmental, safety, and compressor component failure concerns associated with current atmospheric rupture assemblies that relieve directly to the atmosphere. The environmental compressor protection assembly contains a spring set to a pre-determined pressure. Lubricant pressure in excess of this pre-determined set pressure results in spring compression and opening of a relief path. The assembly preferably remains in a full open position and must be must be manually reset to the closed position to prevent fluid flow in the system. The relief path can lead to a fluid reservoir, a container, or directly back into the compressor frame. Flow of lubricant through the relief path results in loss of flow to the lubrication system.

  • Publication number: 20110231114
    Abstract: A fluid flow monitoring system including one or more fluid flow dispensing valves each including a piston. Fluid flow sensors are associated with the fluid flow dispensing valves for measuring fluid flow. The fluid flow sensors include a housing with a magnet positioned therein and a piston follower is coupled to the magnet. The piston follower includes a shoulder portion positioned within the housing. A spring is operative to bias the magnet and piston follower towards the piston during operation so that piston movement is transmitted to the magnet. The housing includes a retainer portion disposed on the housing that confronts the shoulder portion of the piston follower whereby the magnet, piston follower, and spring are retained within the housing. The system also includes a fluid flow monitor that includes a microprocessor programmed to convert cycle signals from the sensors to fluid flow information.

  • Patent number: 7970558
    Abstract: A method for monitoring a signal from a cycle switch mounted to a lubrication divider block system. The method comprises receiving a signal from a remotely located cycle switch that is mounted to a divider block, wherein the cycle switch is responsive to the motion of a piston in the divider block. The number of cycles of the cycle switch are counted based on the signal from the cycle switch. The number of cycles is stored in a computer readable medium and the amount of lubricant used is calculated based on the number of cycles. The amount of lubricant used is then stored in the computer readable storage medium.

  • Patent number: 7720574
    Abstract: A fluid flow monitoring, evaluation, and control system providing accurate dispensing of fluids in low volume, high pressure systems. The system includes one or more fluid flow sensors mounted on positive displacement dispensing valves and a processor that receives cycle signals from the fluid flow sensors to determine fluid flow information. If the fluid flow is not within specified limits, a signal is sent to a pump control device to adjust the pump to return the fluid flow to desired level. A dispensing valve can include a display to show cycle time or other fluid flow measurement. The system can include dispensing valves having single inputs and single outputs for measuring fluid dispensed at a point of use, which measurement can be compared to measurements taken at a divider block earlier in the hydraulic path to verify that fluid sent into the path was actually dispensed.

  • Patent number: 7461670
    Abstract: A cycle indicator is provided for monitoring movement of a fluid control piston of a divider block for a fluid distribution system. The cycle indicator connects to the divider block in a manner that allows fluid communication between the divider block and the cycle indicator. The cycle indicator includes a spring-biased piston follower that extends into the divider block through a housing so that movement of the fluid control piston is translated to the piston follower. The piston follower extends into the divider block through an opening in the housing. The opening is not sealed allowing fluid within the divider block cylinder to flow past the piston follower and into the housing. Since there is no relative movement between the seal and any moving part such as the piston follower fluid leakage is eliminated or at least substantially reduced. An internal magnet is coupled to the piston follower and activates an external magnet that provides a visual indication of the movement of the fluid control piston.

  • Patent number: 7379827
    Abstract: A fluid flow monitoring and evaluation system providing high accuracy for fluid flow systems having low volumes and high pressure includes fluid flow sensors mounted on positive displacement dispensing valves and a fluid flow monitor that received cycle signals from the fluid flow sensors and processes the cycle signals to determine fluid flow information. Information can be downloaded in from the monitor, even in an explosion rated environment, using infra-red link or data can be transmitted, for example via satellite, for posting on the Internet. The system can include dispensing valves having single inputs and single outputs for measuring fluid dispensed at a point of use, which measurement can be compared to measurements taken at a divider block earlier in the hydraulic path to verify that fluid sent into the path was actually dispensed. A novel fluid flow sensor prevents loss of internal components, yet allows internal components to be removed for repair.

  • Patent number: 7096889
    Abstract: The invention is a divider block assembly suitable for use at high fluid pressures. Applicant has found that divider blocks in common use deform sufficient at high pressures to have an adverse affect on accurate fluid delivery and component longevity. A preferred high pressure divider block uses divider block sections engineered for high pressure applications with substantially thicker material surrounding the piston bore, utilizing precise bolt placement on the divider block sections to ensure even pressure to prevent distortion of the piston bore, and engineered base plate inlet and end sections that allow mounting of divider blocks without the addition of extra intermediate sections to reduce leak paths and bolts to secure the base together more firmly, all bolts being torqued to prevent distortion while sealing fluid passages. The use of any of these aspects separately can improve performance, and not all are required in every embodiment.

  • Publication number: 20010018277
    Abstract: A reorientable electrical outlet employs rotatable female electrical receptacle(s) to allow rotation of a male plug while connected in the rotatable female electrical receptacle. The disclosed technique is adaptable to a variety of rotatable female electrical receptacles ranging from typical residential two receptacles, polarized/grounded receptacles, and non-grounded receptacles. The prongs of a male plug may be inserted into the rotatable female electrical receptacle and rotated to desired positions and remain substantially fixed. Male plug interference with other electrical receptacles is minimized. Safety features are provided by placement of electrical connections on the back of a rotatable or fixed receptacle.
