Abstract: Internal combustion engine exhaust filter devices and the like are regenerated by placement in a reclamation or burn-off furnace, raising the temperature to at least about 800° F. to 900° F. and conducting relatively low volumes of low pressure air through the filter media to combust entrapped particulates and other materials residing on the filter media. The reclamation furnace includes an afterburner for combusting materials discharged from the filter devices into the furnace chamber so that complete combustion of materials is accomplished before discharge from the furnace. The flow of combustion air for the filter devices is controlled by manifolding and valving connected to a source and the oxygen content of combustion air may be enhanced by a separate source of oxygen injected into the combustion air flow stream.

Abstract: This invention relates to a leader for use in processing lengthy strips of continuous business forms assemblies. The leader includes feeding means complemental to that of the forms assemblies and one or more transverse areas of pressure-sensitive adhesive for temporary positive attachment, one edge portion being applicable to detachment and application over the leading edge of the endmost portion of the form assembly and the other to a major body portion of the assembly. The leader may also have several other embodiments such as a folded portion for attachment to the forms leader edge. The leader is especially applicable to initiating data processing operations of forms assemblies on printers of various feeding types.

Abstract: This invention relates to an improved method of controlling temperatures within a cleaning or reclamation furnace which is normally used to reclaim metal parts contaminated with combustible materials by pyrolyzing the combustible materials. A reclamation furnace usually includes a primary heat-input burner employed to heat the contaminated parts in the primary heating chamber, an afterburner chamber contained within the heating chamber having a secondary burner to burn volatile gases which are given off by the combustible materials as the parts are heated, and two separately-controlled automatic valve and spray nozzle assemblies connected to the primary heating chamber. Each nozzle assembly is connected to a pressurized water source to deliver a water-spray injection into the heating chamber.

Abstract: A method for preventing fires and explosions and thus controlling excess temperature within a burn-off or reclamation furnace including a water injection nozzle within the furnace, an automatic valve assembly connected to a source of water under pressure to turn the water on and off, an input burner to heat contaminate materials, an afterburner to burn volatile gases given off by the contaminate materials as they are heated, a temperature sensor located in the discharge from the afterburner to actuate the automatic valve assembly open and closed responsive to the temperature of the discharge, the temperature of the discharge depending on the rate of emission of volatile gases from the contaminate material so that if a high emission rate causes a predetermined temperature to be exceeded the valve assembly opens and the water injection nozzle sprays water on the contaminate materials to cool them and decrease the emission rate until the valve assembly closes.
