Patent number: 4992039Abstract: A pulse combustion energy system including a pulse combustor coupled to a processing tube for flowing material to be processed therethrough, the processing tube being coupled to a pair of cyclone collectors for receiving the material flowing therefrom. An optional recycling section is coupled to the cyclone collectors for flowing vapor from the cyclone collectors back to the upstream end of the processing tube. The pulse combustor includes a rotary valve, a combustion chamber, an inner tail pipe and an outer tail pipe. The combustion chamber and inner tail pipe are conical and tubular sections mounted in longitudinal compression, and the compressive forces are transmitted externally across the junction of the combustion chamber and tail pipe by a strongback assembly. The rotary valve includes first, second, and third closely adjacent cylinders defining an interior air chamber. The cylinders have radially oriented, substantially aligned apertures which define an air intake.Type: GrantFiled: February 13, 1989Date of Patent: February 12, 1991Assignee: NEA Technologies, Inc.Inventor: Hanford N. Lockwood, Jr.

Patent number: 4911403Abstract: A shut-off valve for use with high pressure gas cylinders is disclosed which is adapted to automatically retain a residual pressure in the cylinder. The valve includes a check plug axially moveable within the housing which has a hard sealing surface, for establishing high pressure seals and a soft sealing surface for establishing low pressure seals. The plug is spring-biased into the closed position with force selected so that it automatically closes and seals the interior of the cylinder once the gas pressure in the cylinder drops to or below a predetermined threshold pressure.Type: GrantFiled: June 22, 1989Date of Patent: March 27, 1990Assignee: NEA TechnologiesInventor: Hanford N.
