Abstract: A method of using hydrocarbon fugitive gases diluted with air as a primary or supplementary fuel for an engine. The composition of the fugitive gases and air in ensured to fall outside the upper and lower explosive limit for the composition. The total volume of the composition is also calculated to be maintained within a predetermined percentage of the volume of the primary fuel supplied to said engine.
Abstract: A water heater for heating potable water used in a boat or vehicle. Exhaust heated by the burner of the water heater is discharged from the burner and is conveyed through an exhaust duct which extends through a water jacket surrounding the burner and which water jacket holds the potable water to be heated. The potable water is heated by the burner and also by the hot exhaust gases in the exhaust duct. Operating components are accessible from one end of the water heater.
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: A toolbox with drawers for holding tools and the like and a display rack for holding and displaying such tools. The display rack is movable vertically relative to the toolbox and may assume a first tool accessible and tool visible position and a second position where the tools are not accessible and are not visible. A locking mechanism maintains the inaccessible tool position of the display rack. Preloaded struts operate to extend the display rack to its tool accessible and tool visible condition when the retaining force on the display rack is released. A retaining mechanism is used to hold the display rack in its elevated position.
Abstract: A cattle handling system comprises a plurality of stall dividers positioned side by side and extending generally parallel to each other. Brackets for mounting the stall dividers are connected directly to a concrete slab and allow for connection of the stall dividers to the brackets in a one man operation without the need for embedding vertical members in the slab. The position of the brackets are located on the concrete slab by use of a mounting jig. The brackets may have a vertical adjustment allowing for an increase or decrease in the working height of the stall dividers.
Abstract: A control system for a turbo charged natural gas engine. A butterfly valve used for fuel control upstream of a carburetor provides non-linear flow response during opening and closing and a flow compensator compensates for the non-linear response. A throttle valve position sensor acts in association with a controller which compares the throttle valve position signal with a predetermined set point and thereby opens or closes the waste gate of the turbo charger which affects oxygen content in the exhaust. A compensator for a throttle valve used with electronic engine controllers is also provided.
Abstract: A diesel/electric appliance for heating coolant within an auxiliary heater circuit and for heating potable water within a potable water circuit. The appliance includes a diesel powered auxiliary heater and a coolant jacket surrounding the burner of the auxiliary heater. Electrical resistance elements are immersed within the coolant jacket to maintain the temperature of the potable water circuit by transferring heat through a heat exchanger to the potable water circuit.

Abstract: A panel or door suspension system used to hang sliding panels or doors. The panel members are hung by an upper bearing assembly with bearings on each side of the longitudinal axis of the panel thereby allowing the weight of the door to bear wholly on the upper bearings and to act centrally and downwardly between the bearings thereby preventing a moment on the bearings. A wedge member attached to the upper portion of the panel allows for vertical adjustment of the panel relative to the bearings and the door frame. A sill assembly beneath the panel allows for stable sliding operation of the panel member, provides for debris drainage and facilitates servicing of the members comprising the sill assembly.

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 filter underdrain system and a method for measuring the water flow through the underdrain filter system. The apparatus includes panel members assembled to form a perforate grid on the filter base structure of an underdrain block. The panels are generally rectangular and have an upper and lower surface. Multiple apertures are provided in the panel member. The number and/or size of the apertures are dimensioned to prevent the egress of filter media and to obtain substantially uniform backwash flow in the underdrain thereby reducing or eliminating water maldistribution.
Abstract: A flame sensor circuit is used to sense the presence or absence of a flame in a burner. A first sensor generates a first intensity signal which is proportional to the light intensity of the flame in the burner. A second sensor generates a second signal produced by the flicker of the flame. The presence of both the first and second signals is sensed and if both are present, an output signal is generated to indicate the presence of the flame in the burner.
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 melting material in the annulus of an oil or gas well and thereby sealing the annulus to prevent shallow gas leakage and the like. Conveniently, the material is positioned within the annulus between the production and surface casing of the well and above the well cement. A heating tool is lowered into position and provides the necessary heat to melt the material. The heating tool may be removed following the sealing of the annulus.
Abstract: Method and apparatus for enhancing the combustion of a process gas of variable composition which gas is used for steam generation in producing heavy oil. The mass flow of the process gas containing hydrocarbons, carbon dioxide and water is measured. It is assumed that the process gas is saturated with water vapor and the water content of the process gas is then obtained. The content of carbon dioxide in the process gas is nominally obtained with an oxygen analyser measuring the flue gas from a steam generator thereby giving a close approximation of hydrocarbon content and allowing an expedited calculation of the energy content and air required. The nominal carbon dioxide value is compared with the calculated carbon dioxide value based on the actual flow of process gas and purchase gas and the oxygen content so that the quantity of carbon dioxide is approximated.
Abstract: A heating tool used for heating cement and/or a ground formation zone and melting billets in a down hole application for sealing oil and gas wells from gas migration. The heating tool has a billet loader which allows a plurality of billets to be loaded into the top of the tool and which billets then pass downward into a magazine and the lowermost heating area of the tool to rest on a billet retainer.
Abstract: A hot water heating system for use in a boat or vehicle which utilises the engine of the vehicle or boat, an AC power source or a fuel powered heater to heat a living area and to heat potable water. Each of the power sources can be utilised independently or in combination depending on the location and operation of the vehicle or boat. A valve is automatically controlled by a thermostat to allow heated fluid to circulate through the living area or to bypass the area. Aquastats are provided to automatically allow potable water to be heated. A display is provided for displaying textual and numerical information in user friendly format relating to the operation of the hot water heating system.
