Abstract: A scrubbing system for removing particulate from an air stream generated during a glass-wool insulation forming process includes a first separator system for removing at least a first portion of the particulate from the air stream, a second separator system, in the form of a single cloud generating vessel, for removing another portion of the particulate, and a third separator system for removing both moisture and a further portion of the particulate. The first separator system is designed to effectively provide a high residence or pre-treatment time for the air stream that enables fine particles to grow into larger particles which are easier to trap and collect, while also allowing the air stream ample time to cool to saturation temperatures. The first and third separator systems combine with the single cloud generating vessel to synergistically enhance the overall efficacy and efficiency of the scrubbing system.

Abstract: The present invention provides an incinerator and a method of firing an incinerator. The incinerator is provided with an oxygen fuel burner. The incinerator is fed with a exhaust stream that includes various impurities such as NOx, CHO2, NH3, and C6H5OH. The exhaust gasses are heated to a temperature high enough to react the impurities to form benign compounds such as CO2, H2O and N2. The burner may be fed with a rich fuel air mixture to improve combustion and to reduce the amount of oxygen required. The flow of gaseous fuel and oxygen to the oxygen-fuel burner are controlled such that the oxygen is less than the stoichiometric ratio required to drive the combustion reaction to completion. The reaction therefore relies upon oxygen within the exhaust stream to drive the combustion reaction to completion. The invention provides an exhaust stream with fewer impurities while consuming less oxygen and fuel therefore cutting operational costs.

Abstract: A scraper for moving friable material. The scraper includes a frame adapted for attachment to a vehicle and an articulated blade. The blade has left and right portions mounted on the frame for pivoting about a substantially horizontal axis transverse to the articulated blade. Each of the left and right portions of the articulated blade is adapted for pivotal movement about the axis between a substantially horizontal lowered position and a raised position, and each portion is independently positionable in at least one position between the lowered position and the raised position. The articulated blade is positionable for engagement with the friable material as the vehicle travels over the friable material for moving a part of the friable material to shape the friable material in accordance with a predetermined design.

Abstract: A regenerative thermal oxidation system for reducing the VOC content of asphalt vapors.

Abstract: In a method for recovering vapors during the dispensing of a bituminous product into a tank, an inlet opening of the tank is closed with a fitting. The bituminous product is dispensed into the tank via the fitting. The bituminous product emits vapors inside the tank. The vapors are exhausted from the tank without direct contact of the vapors with moving parts. The vapors are transported to a condenser, and condensed to a liquid in the condenser. The condensed liquid is returned to the tank via the fitting.

Abstract: Bottles or like articles are fed singly in ungrouped bottle-to-bottle contact in a continuous path by gravity feed in sequence onto horizontally moved cases carried by a conveyor disposed below the line of movement of the bottles or like articles, the case conveyor moving the cases at a predetermined speed. The bottles are conveyed to the cases on inclined paths and/or spaced rails, the bottles being slidably movable on portions adjacent the inclined paths and/or spaced rails. In one embodiment the bottles are suspended from rails in bottle-to-bottle contact. Detectors may be provided for detecting the height of the bottles, disposition of the caps thereon, positioning of the bottles in the cases, and eliminating jamming or improper spacing of the cases.

Abstract: A control for modulating the duty cycle of diesel engine glow plugs has two heat sensitive, normally closed switches each thermally coupled to a respective positive temperature coefficient (PTC) of resistivity heater in turn thermally coupled to and mounted on a common heat sink. The heat sensitive switches are serially connected to each other, to an ignition switch and to a glow plug relay. The PTC heaters are connected to a point between the heat sensitive switches and the relay and to ground. A third PTC heater is mounted on the heat sink intermediate the first and second heaters and thermally coupled to the heat sink. The third heater is connected to an alternator and serves to cut off power to the glow plugs after a selected after glow stage. The two heat sensitive switches can be selected to open at approximately the same temperature for a random operating mode or at slightly different temperatures for a sequential operating mode.
