Abstract: A method for preventing mechanical oscillation in a wind power plant, the method comprising the steps of determining wind speed, controlling a generator of the power plant with speed control when the wind speed is below a predefined limit (w 1 ) to maintain the rotation speed of the generator below a predefined first limit (v 1 ), detecting the increase of wind speed above the predefined limit (w 1 ), controlling the electric drive of the wind power plant generator to torque control by using a predefined crossover torque (T 1 ) in response to the wind speed increasing above a predefined limit, maintaining the crossover torque (T 1 ) as the reference torque for the electric drive until the rotation speed of the generator has increased above a predefined second limit (v 2 ), and controlling the electric drive of the wind power plant generator with torque control while the rotation speed of the generator remains above the predefined second limit (v 2 ).

A metal melting furnace is provided with one or more liquid fuel/oxygen burners such that each burner nozzle is housed within a water-cooled annular shield projecting and diverging beyond the nozzle discharge face and terminating in a convexly curved edge. Each burner 12 is basically formed of concentric tubes consisting of an inner liquid fuel supply tube 31, an oxygen supply pipe 13, and an outer tube 14, the annulus between the pipe 13 and the outer tube being sub-divided by baffle 26 to form a double water-cooled shield. A nozzle member 17, having oxygen discharge passages 18 extending therethrough and symmetrically inclined to the longitudinal axis thereof, is formed as a separate component of copper, stainless steel or ceramic and is housed within said water-shield at the discharge end 16 of the oxygen supply pipe. The tapered end portion 20 of the shield extends beyond the nozzle discharge face 19, the inner shield wall 21 being of outwardly diverging configuration, and terminates in a convexedly-curve edge 25. Liquid fuel supply passages 28 are spaced inwardly of the oxygen passages 18 to terminate short of the discharge face as in Specification 1,044,151, and are connected to the outer end 30 of the supply pipe 31 contained by tube 13, said supply incorporating a non-return valve 32 as described in the above Specification. In alternative arrangements, the liquid fuel passages may feed fuel through the side walls of the oxygen or the liquid fuel passages may extend to the discharge face 17 of the nozzle member.

Trichloroethylene and perchloroethylene are prepared by passing 1,2-dichloroethane and chlorine together with pentachloroethane over a porous catalyst at elevated temperature. The catalyst may be activated charcoal, e.g. that produced from mineral coal and having a total pore volume of 1À4 to 1À5 c.c./gram and a mean pore radius of 8À5 to 9À5Š. The proportion of perchloroethylene in the product may be increased by passing the trichloroethylene to a second reactor where it is chlorinated to pentachloroethane which is recycled to the first reactor. 1,1,2,2-Tetrachloroethane may be mixed with the reactants and the process may be conducted autothermally (i.e. the heat of chlorination of 1 2-dichloroethane substantially balances the energy required for the splitting of the pentachloroethane).

At a certain speed of rotation of the shaft 15 the centre of gravity of the system formed by weights 21, 22 is on the shaft 15 but when the shaft is driven at a higher speed the weight 21 moves radially outwards comprising spring 20 to give an additional unbalance to the shaft. The weights 21, 22 are connected by clips 23 and fixed or adjustable stops limit the radial movement of weight 21. An additional control weight 24 is fixed to the weight 21. The shaft is rotated by an engine 1 through belt drive 13, a clutch 4 and a twospeed gear-box formed by gears 7, 9 and 10. The weights 18 and the weight 21 and its movement are arranged so that the same centrifugal force is produced at both speeds.
