Title: Method and mechanism for changing the wingplan geometry of aeroplanes in flight
IPC: B64C9/24
Filed: 1980-04-16
Abstract: A method and mechanism for changing the wingplan geometry of the main wing of an aeroplane in flight. A slat (1) is pivotally mounted to the main wing (4) with its leading edge matching that of the main wing. By sliding the slat forward the slat is angularly projected over the wing leading edge to form an adjustable angle (a) thereby increasing the wing chord. Sliding the slat downwards creates a wing slot forming an angle (b) thereby changing the wing camber. These sliding operations collectively improve the aeroplane flight stability at low speeds on take-off and when landing. <IMAGE>

Inventor: NEVILLE ROY
IPC: B23K9/067
Filed: 1982-10-26
Abstract: A welding tool comprises a solenoid body 1 wound with a coil of wire 2 about a hollow core 3. A central core contains a fixed iron part 4 and a movable iron part 5. The core part 5 has a threaded brass studding 6 connected thereto and which passes with clearance through the part 4 to connect with a conducting leaf 7 which is in series with the solenoid coil and serves as a mechanically flexible welding current feed to a welding electrode holder 8 via the studding 6 and the part 5.

Title: Catalytic pollution control system for gas turbine exhaust
Inventor: CARBERG WILLIAM GEORGE
IPC: F02C3/30
Filed: 1983-11-18
Abstract: In a system which employs a catalyst 50 to react injected ammonia with NOx from the combustor 14 of a gas turbine to reduce atmospheric emission of NOx from the system, rapid control of ammonia injection is achieved using a prediction of the NOx being generated in dependence upon the operating conditions of the combustor 14. The amount of NOx downstream of catalyst 50 is measured and compared to a preset NOx value (setpoint) to generate an error signal which is used to control NH3 injection to adjust the measured NOx toward the setpoint. The NOx predictor 72 generates signal 74 based on e.g. pressure, temperature, fuel-and air-flow of gas turbine 12 which signal is fed to NH3 control 52 along with actual NOx signal 62,64 and NOx setpoint 78. The system may be used in a steam and gas turbine combined plant. <IMAGE>
