  • Patent number: 6442930
    Abstract: A turbofan engine includes a pulse detonation system to create a temperature rise and a pressure rise within the engine to generate thrust from the engine. The system includes a pulse detonation augmentor including a shock tube sub-system. The shock tube sub-system includes a plurality of shock tubes which mix air and fuel introduced to the pulse detonation augmentor and detonate the mixture. The detonation creates hot combustion gases which are directed from the engine to produce thrust for the engine. Alternatively, the system includes a pulse detonation augmentation system that replaces a core engine of a turbo-fan engine.

  • Patent number: 6323665
    Abstract: A system and method for burning-in an integrated circuit chip including at least a socket capable of receiving and supporting the chip, electrical leads in the socket for connecting to corresponding leads on the chip, and a heat sink in thermal contact with a cooling medium. The heat sink includes a thermal interface in releasable thermal contact with the integrated circuit in the socket. The heat sink removes more heat from the integrated circuit than is generated during the burn-in process and the integrated circuit is maintained within a predetermined desired temperature range by monitoring the temperature of the integrated circuit and supplying make-up heat as needed. Multiple sockets can be grouped together and cooled by a manifolded cooling system, with the temperature of each integrated circuit being individually monitored and controlled.

  • Patent number: 5430346
    Abstract: A spark plug for an internal combustion engine wherein a ring shaped ground electrode has a uniform annular hole with an internal diameter about 0.80 to 1.25 times the outer diameter of the center electrode. The ground electrode is vertically spaced below the center electrode and is concentric therewith. The ground electrode is connected to one or more mounting posts attached to a spark plug metal housing. Firing surfaces of the ground and center electrode have platinum alloy inserts laser welded in place. The spark from the center electrode to the ground electrode has multiple paths and results in a spark plug which improves fuel combustion, increases gasoline mileage and engine horsepower and torque and significantly reduces the smolder time or ignition delay time and consequently reduces environmental pollutants of nitrogen oxide, carbon monoxide and other hydrocarbons.
