Abstract: An isotope separator includes a cylindrical chamber having first and second ends, and a length “L.” Inside the chamber, an E×B field is applied to produce plasma rotation. The energy in the plasma rotation is chosen to be much higher than the electron temperature which is clamped by radiation. As the plasma then transits the chamber through the length “L”, the electrons cool the thermal temperature of the isotope ions while maintaining the rotation. Under these conditions, the minority and majority isotopes become substantially separated from each other before they exit the chamber. To achieve this result, E×B is determined using mathematically derived expressions and, in compliance with these parameters, the length “L” of the chamber is determined so that the plasma residence time in the chamber, &tgr;1, will be greater than the cooling time, &tgr;2 (&tgr;1>&tgr;2) necessary to affect isotope separation.

Abstract: An oil circulation system that monitors filter life and can notify the operator of the oil filter life status. The oil filter life is calculated based upon oil pressure sensors on the inlet and outlet of the oil filter. Pressure drop, oil temperature, and engine speed from the tachometer are factored into an algorithm to calculate the percentage of oil filter life remaining. If the percentage is below the predetermined level, the system will warn the operator to change the filter. If the percentage is above the predetermined level, the system will record the extent of oil filter life remaining and repeat the process.

Abstract: The present invention is an apparatus and process for cleaning substrates using dense fluids under the influence of a continuous centrifugal force. Dense fluid centrifugal separations resolve many problems associated with conventional dense fluid cleaning technology. These include elimination of pooling and supercooling of liquid carbon dioxide trapped within pores and cavities of a substrate—leading to formation of dry ice and recontamination of substrate, ability to precision clean using one unit volume of dense fluid per cleaning operation and ability to remove small insoluble particles from deep voids or cavities. The present invention can perform solvent-aided separation processes heretofore not possible using conventional dense fluid technology. These include liquid-liquid, liquid-supercritical-fluid, froth flotation and centrifugal phase-shift separations.

Abstract: A paraffin filter system (10) includes an in-line low-profile particulate filter (20) connected to a suction tube (14) which is used as an inlet to the paraffin filter system (10). A paraffin pump (54) pumps the melted paraffin from a paraffin spa (12) through the particulate filter (20) to a transfer container (11) via a discharge tube (22). A heater (78) is controlled by control logic (146) to operate in certain modes to melt any residual paraffin in the filter (20) and pump (54) before operation of the pump (54). The control logic (146) provides various modes of operation of the filter system (10) to assure that the system is ready to operate, irrespective of the operation of a control panel switch (6) by the user. When the paraffin is transferred back to the spa (12) from the transfer container (11), the melted paraffin is carried through a bacteria filter (21) in the filter system (10).

Abstract: The invention provides methods and an apparatus for more efficiently and economically producing purified water from sea water or some other salty or brackish water source. The efficiency is derived from the co-location with a power plant or other thermal generating source that will heat the feed water. Reverse osmosis membrane filtration systems work optimally when the feed water is at certain higher temperature, where that temperature is typically higher than the feed water at ambient temperatures. By using the heated sea water as the byproduct of the power plant electricity generating process and if necessary mixing it with ambient temperature sea water, if needed to lower the water temperature, and using this feed water with a higher temperature than ambient water temperature, the efficiency of the reverse osmosis system can be increased.

Abstract: A fuel system (10) comprises a tank (12), a pump (14), heat exchangers (16 & 18) and a filter (20) in series fluid flow relationship. A fuel metering unit (24) returns a proportion of the filtered fuel to the tank (12) and is controlled by the engine electronic control (30). The system (10) operates so that fluid is not returned to the tank (12) when a pressure differential of the order of 5 psi is detected across the fluid filter (20) and the temperature of the fluid is below 0° C. The fluid is not returned to the tank (12) for a period of time to reduce the flow of fluid passing through the heat exchangers (16 & 18). The reduced flow of fluid passing through the heat exchangers (16 & 18) is heated to a temperature sufficient to melt any solidified impurities blocking the fluid filter (20).

Abstract: A system is provided for removing dissolved metals from industrial wastewater by electrocoagulation. The system includes an electrocoagulation reactor with a DC power supply having an insulation support enclosure with positive and negative electrode plates disposed thereon. The electrode plates are insulated for each other but remain in direct contact with the wastewater as it flows between the electrodes. The DC power supply induces opposite charges on alternate electrodes thereby generating an electric field between adjacent electrodes to cause the electrodes to ionize and go into solution for interaction with the contaminants in the wastewater as it flows through the reactor. The reactor is housed in a pressure vessel container so the exterior pressure on the reactor is higher than its internal pressure preventing leakage of fluids and oxygen and hydrogen gases produced in the reactor by decomposition of water.

Upon reaching a predetermined pressure, e.g. when the media of the oil filter becomes clogged, an opening 52 in the end cap opens to allow the oil to bypass the filter media. However, the thermal sensitive material precludes bypass flow through the end cap (e.g. during initial operation of the engine when a pressure surge may occur) until a predetermined oil temperature is attained.

Abstract: A fuel control device 220 includes a restriction 294 and a check valve 292 disposed between a fuel return conduit 236 and a fuel injection supply conduit 227. In operation, fuel from tank 202 flows into the control device via conduit 208 is filtered through filter 222 flowing to an injection pump 230 outlet conduit 228. Excess fuel is returned to the control device and is then directed either back to the tank 202 via conduit 234 or is mixed with incoming fuel via conduit 235 and a two-position temperature responsive diverter valve 290. The restriction and check valve provide the benefit of allowing a continuous air bleed to purge any incoming air or vapor from the fuel supply system back to the fuel tank 202, while preventing unfiltered fuel flow from the fuel return outlet port to the filtered fuel outlet port.

Abstract: A simple, reliable, inexpensive, and efficient anaerobic digester for treating organic wastes at a shortened residence time is described. The anaerobic digester is a multi-chambered digester that can handle wastewater and sludge in a large volume at a high flow rate. The digester also allows collection of methane gas for use as an energy source. The reactor is based on a sequential series of reaction chambers in a design that does not require internal moving parts. The volume of the chambers is adjusted to control the relative residence time of the waste to select an anaerobic microorganism group or groups that can efficiently digest the waste presented to that chamber. Under most conditions, no addition of bacteria is necessary. The digester works efficiently using microbes native to the waste material. After the reaction chambers and just prior to leaving as effluent, a settling chamber is located to reclaim the microbes and remove additional solids.

Abstract: Steaming filter aid cakes in-place in a pressure leaf filter is a simple, inexpensive, and reliable technique for insuring that all collected pathogens are destroyed and never released back into the environment. Filter aids including diatomaceous earth reduce giardia and cryptosporidium by at least 6 logs. D.E. filtration allows the flexibility to adjust the dosage for bodyfeed and the grade to suit changing water conditions, and the process of bodyfeeding filter aids is the only technology that seals its own leaks. After sterilization, the filter aids can be recycled. With hydrocyclones the contaminants can be separated from the filter aids and up to 90% of the filter aid can be recovered. This makes filter aid treatment a very cost effective treatment for large plants as well as the smaller plants where this technology has been used in the past.
