Abstract:
A skimmer used to remove both heavy and light oil from a body of water or for the removal of either light or heavy oil and a method of operation of the skimmer. The heavier oil is removed from a first location on a rotating member and the lighter oil is removed from a second location on the rotating member. The oil removed at both locations is collected at a single location and a pump removes the oil from the skimmer.
Abstract:
Apparatus and method for collecting fugitive combustible gases and fugitive combustible gases in dilute form and adding the gases as a supplemental fuel source to an engine. The fugitive combustible gases are added to the air inletted to the air supply and control is provided to allow adjustment of the normal fuel supplied to the engine following the addition of the fugitive combustible gases . The fugitive combustible gases provide an energy source for the engine and the combustion of the gases reduces the greenhouse effect if the gases contain methane.
Abstract:
A muffler assembly has a housing and an internal and replaceable core assembly. The core assembly may contain emission reduction elements to reduce the emissions from the engine and/or sound reducing elements. The core assembly is replaced within the housing when the emission reduction elements become ineffective or when the user desired to otherwise replace the internal core assembly without replacing the muffler housing or assembly components. The core assembly may take the form of a sealed cartridge to isolate exhaust treatment apparatuses from the ambient environment.
Abstract:
Method and apparatus for melting a material and squeezing the melted material through casing perforations into a fault within the cement or formation of an oil or gas well. A heating tool carries solid material which is melted at depth within the well and adjacent to the casing perforations. The liquefied material is forced through the perforations and into the formation or the well cement. When the material cools and solidifies, the faults become sealed.
Abstract:
A panel forming method and apparatus used compressed fibrous material such as straw, hay and the like. The fibrous material from bales is debailled by debailler rollers and passed to straw walkers. The straw walkers move the material to crop shredders which deposit the shredded fiber on a conveyor. A leveller roller smooths the mat on the conveyor which mat moves to a picker roller. The picker roller moves the crop into a chute and a compression cavity where the material is severed and compressed by a reciprocating ram. The severed and compressed material has glued paper applied to its upper and lower surfaces and thereafter moves between heated platens for curing the glue. The severed and compressed material now forming a longitudinal panel is pulled by puller rollers and subsequently severed into panels of a desired length.
Abstract:
Disclosed herein is an efficient heat generation device where fuel is burnt in a pressure gain combustion process. The heat generating system has an inner combustion chamber that is housed in heat exchangers. The combustion chamber walls, in one form, include fluid conduits. While different fluids could be utilized, water is most common and the term water herein is intended to define water and all functional equivalents. The water conduits (tubes) may be multi-pass longitudinal, parallel to the combustor axis or they may be winded around the combustion chamber in a spiral fashion. The combustion products exiting the combustion chamber enter the outer liner where water tube bundles extract the heat of the combustion. One embodiment also utilizes an air preheating stage. Heated water and steam generated in the heat exchanger stages wrapped around the combustor enters the final heating stage where it passes through the flame accelerators in the combustion chamber. The flame accelerators within the combustion chamber are in the hottest region in the combustor and therefore exchanging heat at high temperatures increases the efficiency of the steam generation cycle. It also increases the produced steam quality.
Abstract:
Disclosed herein is a use of pulsed combustion to convert chemical energy to usable heat. For example, in boilers, heat is generated by burning fuel at burners and transferring the heat to water or other fluids, including air, through heat exchangers. In one form, these heated fluids may then be utilized to assist in removing oil from oil sand reservoirs.
Abstract:
Method to provide fugitive gases to an engine. A source of fugitive gases is directed to the air intake of the engine. A fugitive gas pipe supplies the fugitive gases to the air intake and a vent allows the fugitive gases to vent to atmosphere. A check valve in the vent inhibits the flow of fugitive gases to the vent and allows the escape of the fugitive gases to the vent if the pressure of the fugitive gases exceeds a predetermined value.
Abstract:
An induction tool for heating well casing and a method for using and manufacturing the tool. The tool comprises a magnetically permeability core and an electrically conductive coil surrounding the entire circumference of the core. The tool generates magnetic flux which flux is used to heat well casing adjacent to or acted upon by the tool. The heated well casing may be used to melt material used for well sealing.
Abstract:
Bait for attracting crustaceans and non-crustaceans which are caught in trap fishery. The bait includes a pelletized carrier composed of ingredients intended for long life in sea water. The pelletized carrier is mixed with specific attractants depending on the desired catch and a fish oil is added to coat the pellets and attractant and to allow for the timed release of the attractant. In experiments to date, it has been found that the use of the pelletized carrier and attractant together with the fish oil coating has been effective as a bait in attracting catch and has an extended life within the traps.
