  • Patent number: 7651607
    Abstract: A chlorinator for wastewater treatment systems having a circulation pump, circulation tank, and return flow line, which includes a reservoir of disinfectant fluid and a dosage container communicating with the reservoir and the circulation tank to dispense a determined quantity of disinfectant during operation of the circulation pump. The dosage container is vented to atmosphere to prevent vacuum lock in operation and communicates with the reservoir at a flow rate substantially smaller than it communicates with the circulation tank. Operation of the circulation pump causes flow through the return line, inducing distribution of the quantity of disinfectant fluid into the circulation tank. As the dosage container outgoing flow rate far exceeds the dosage container incoming flow rate, once the disinfectant level drops below the point of communication between the dosage container and the circulation tank, no her disinfectant is drawn into the circulation tank.

  • Publication number: 20090101575
    Abstract: A rapid one-pass liquid filtration system efficiently concentrates biological particles that are suspended in liquid from a dilute feed suspension. A sample concentrate or retentate suspension is retained while eliminating the separated fluid in a separate flow stream. Suspended biological particles include such materials as proteins/toxins, viruses, DNA, and/or bacteria in the size range of approximately 0.001 micron to 20 microns diameter. Concentration of these particles is advantageous for detection of target particles in a dilute suspension, because concentrating them into a small volume makes them easier to detect. Additional concentration stages may be added in “cascade” fashion, in order to concentrate particles below the size cut of each preceding stage remaining in the separated fluid in a concentrated sample suspension. This process can also be used to create a “band-pass” concentration for concentration of a particular target size particle within a narrow range.

    Abstract: A lubrication system having an oil filter modified to replace or supplement the performance of lubricant additives that may be used within an internal combustion engine to increase the performance of a lubricant. The formulation of the lubricant is changed in accordance with the chemicals placed in the oil filter. For example, when the oil filter contains a strong base, the lubricant concentration of detergent will decrease, in some cases to zero, while the dispersant concentration in the lubricant will increase. The dispersant is the ideal weak base to neutralize combustion acid at the piston ring zone, carry the resultant weak base-combustion acid complex to the strong base in the oil filter, undergo ion exchange with the strong base, immobilize the acid in the oil filter and recycle back to the piston ring zone for reuse as an acid neutralization agent.

  • Patent number: 7491321
    Abstract: Contaminants are removed from fluid in a system where the fluid is sprayed into an air head at the top of a tank through a diffuser and withdrawn through a pick-up tube. A solenoid valve operates to allow oxygen-containing gas from a compressed gas source to flow into the tank through a shuttle valve, which is opened by the gas pressure. Simultaneously, a drain valve connected to the shuttle valve opens a drain, venting water and air from the tank. The solenoid valve also operates to close the gas supply line and connect the shuttle valve through a vent to atmosphere. Pressure within the tank closes the shuttle valve, which in turn closes the drain valve and disconnects the shuttle valve from the tank. A one-way-flow valve prevents fluid or gas from flowing from the tank backwards through the shuttle valve to the solenoid valve and out the vent.

  • Publication number: 20080217233
    Abstract: A chlorinator for wastewater treatment systems having a circulation pump, circulation tank, and return flow line, which includes a reservoir of disinfectant fluid and a dosage container communicating with the reservoir and the circulation tank to dispense a determined quantity of disinfectant during operation of the circulation pump. The dosage container is vented to atmosphere to prevent vacuum lock in operation and communicates with the reservoir at a flow rate substantially smaller than it communicates with the circulation tank. Operation of the circulation pump causes flow through the return line, inducing distribution of the quantity of disinfectant fluid into the circulation tank. As the dosage container outgoing flow rate far exceeds the dosage container incoming flow rate, once the disinfectant level drops below the point of communication between the dosage container and the circulation tank, no her disinfectant is drawn into the circulation tank.
