Publication number: 20090139215Abstract: A method is provided for operating a diesel engine with reduced emissions. The method comprises combusting a first biodiesel blend fuel in a diesel engine resulting in the production of diesel exhaust gases containing NOx. The diesel exhaust gases are admixed with a second biodiesel blend fuel, and the second biodiesel blend fuel is hydrolyzed to form reducing agents. The diesel exhaust gases containing NOx are passed through an NOx-reducing catalyst to reduce the NOx through a selective catalytic reduction reaction with the reducing agents.

Patent number: 4582423Abstract: There is disclosed a diazotype copier for deodorizing developed diazocopy material. The copier includes a light source for exposing the diazotype copy material and a developing chamber for developing the exposed copy material. After exiting the developing chamber, the developed material passes under a heating chamber which includes a heating element and means for providing a flow of air into the chamber, around the heating element, and across the developed copy material. The heating air releases the entrapped ammonia vapors from the developed copy material. Thereafter, the air, including the released ammonia vapors, flows toward and into a scavenging device which neutralizes the ammonia vapors.Type: GrantFiled: September 17, 1984Date of Patent: April 15, 1986Assignee: Blu-Ray IncorporatedInventors: Robert Putnam, Robert Harris, George Norton

Patent number: 4056225Abstract: A centrifuge rotor having a sealing element which automatically controls in response to the centrifugation operation the fluid communication between separate fluid mixture chambers within the rotor. The sealing element is situated within the rotor above an annular and an inner chamber used for containing a fluid mixture. When the rotor is assembled and stationary, the sealing element establishes a seal between the respective chambers. During the rotation of the rotor in a centrifuge, the centrifugally induced pressure exerted by the fluid mixture moves the sealing element, releasing the seal between the respective chambers and allowing fluid communication between the chambers. As the rotor returns to a stationary position and the centrifugally induced pressure of the fluid mixture subsides, the sealing element automatically re-establishes the seal between the respective chambers.Type: GrantFiled: April 29, 1976Date of Patent: November 1, 1977Inventor: George Norton Hein, Jr.

Patent number: 4046317Abstract: An air levitation jet located in the center of a rotor seat to provide a supporting and holding air flow between a rotor and the rotor seat. Integrally formed within both the rotor and the rotor seat are conical and frustoconical portions which respectively establish a conical flow path and an adjoining frustoconical flow path to aid not only in the centering of the rotor within the rotor seat, but also in the retaining of the rotor in alignment with its rotational axis. Air under pressure exiting the levitation air jet in the center of the rotor seat proceeds along the conical flow path and into the frustoconical flow path with sufficient velocity to establish a reduced pressure in the flow path between the rotor and rotor seat that is less than atmospheric pressure, causing the rotor to remain securely positioned on a cushion of air within the rotor seat.Type: GrantFiled: April 29, 1976Date of Patent: September 6, 1977Inventor: George Norton Hein, Jr.
