Abstract: An apparatus and the method of using the apparatus to form a wall. Initially, a pair of vertical wall guides are mounted upright at selected locations. The guides are made in two parts, a front guide and a rear guide, so the guides can be moved toward and away from each other to compensate for uneven walls and thicknesses of stone. Staves or forming boards are mounted horizontally between the wall guides by threaded bolts, to form a guide for the stones.

Abstract: A transient control system for a gas turbine controller that cooperates with a droop speed governor to generate fuel commands regulating fuel flow to combustors of the gas turbine. The transient control system provides compensation for variations in the power output of a gas turbine while the turbine is in transient phase operation. A proportional plus integral controller in the transient control system establishes a power output set point at the initiation of a transfer phase and compares the set point to the current power output of the gas turbine. An output signal indicative of the current power output and its set point generated by the proportional plus integral controller is applied to the droop governor to compensate for variations in the power output of the gas turbine during the transient phase.

Abstract: Hydrogen is used as the fuel source in a gas turbine combined cycle power plant. The hydrogen may be combusted in either a mixture of compressed air and steam or a mixture of pure oxygen and steam. In either case, the work of compression associated with pressurizing the oxidant for the combustion process is considerably reduced since steam, rather than excess air, is used to moderate combustion temperature, as well as to cool the turbine components. The steam is produced by transferring heat from the turbine exhaust gas to feed water. Since no hydrocarbon fuel is used, fuel bound NOx is eliminated. Moreover, if pure oxygen is used, rather than air, for the combustion of the hydrogen, then the only emission from the power plant is water vapor, which may be condensed and returned to the cycle.

Abstract: A supersonic engine having an ejector/suppressor. The engine has a rear discharge portion with an ambient air inlet section, a mixing section, and a rear discharge section. For noise suppression, arms mounted in the air inlet section are moved to open air inlet passageways causing air to flow there through. Primary exhaust from the engine flows through primary passageways interspersed with the ambient air passageways. The primary supersonic air from the primary passageways mixes with the ambient air in the mixing section and flows out the final nozzle which is in the open position. For cruise mode, the arms are moved to close the air inlet passageways, and the final nozzle is in a position to cause the flow upstream thereof to be a subsonic, and the flow aft of the final nozzle to be supersonic. The arms can be placed in an intermediate position for thrust reversal, with the final nozzle being moved a blocking position.

Abstract: A two-stage mixer ejector concept ("TSMEC") is disclosed for suppressing the noise emanated by jet aircraft. This TSMEC was designed to help older engines meet the stringent new federal noise regulations, known as "Stage III". In an illustrated embodiment, the TSMEC comprises: a lobed engine nozzle attached to the rear of a turbofan engine; a short shroud that straddles the exit end of the engine nozzle; two rings of convergent/divergent primary and secondary lobes within the engine nozzle shroud and; and a ring of arcuate gaps that precede the shroud and the second nozzle ring. The lobes are complimentary shaped to rapidly mix the turbine's hot exhaust flow with cooler air including entrained ambient air, at supersonic speed. This drastically reduces the jet exhaust's velocity and increases jet mixing, thereby reducing the jet noise.

Abstract: A method of checking the efficiency of a catalytic converter in an internal combustion engine in which a ratio is formed from the amplitude of the output signal of a lambda probe arranged behind the catalytic converter and from the amplitude of the output signal of a lambda probe arranged in front of the catalytic converter. The ratio is compared with a threshold value, the catalytic converter being recognized as deficient if the ratio is less than the threshold value. In order to compensate for the lack of sharpness resulting from the manufacturing process and the aging of the probe, the method provides for determining the efficiency of the catalyst in which an extreme value of the corresponding probe output signal is determined for each probe after each probe reversal.
