Abstract: ABSTRACT OF THE DISCLOSURE Apparatus for applying power to at least two heater filaments of two glow plugs in a diesel engine, or to a heater of one glow plug and a ballast load having substantially the same maximum rated voltage as the filament, is disclosed.  The power source has a supply voltage greater than the maximum rated voltage of the filament and sufficiently high to cause an overheating temperat-ure capable of burning out the filaments under continuous operation.  A switch is operable in a first position to prevent the application of the supply volt-age to the apparatus, operable in a second position to apply the supply voltage to the apparatus, and operable in a third position to maintain the condition of the second position and to apply the supply voltage to the apparatus and to a starter for the engine.  The apparatus causes the application of full supply voltage to each of the filaments by turning the switch from the first to the second position, and, after a preheat time period which varies as an inverse function of available supply voltage and equals the time required to raise a filament from ambient temperature to a higher operating temperature sufficient for diesel engine starting, causes reduction of the voltage applied to the filaments and maintains the operating temperature thereof for a prestart time period.  The apparatus also ensures that, after the switch is turned from the second to the third position,  the application of the reduced voltage to the filaments is continued for an afterglow time period predetermined by the amount of time required for smooth engine idling and to minimize engine noise and white smoke emission.

Abstract: ABSTRACT OF THE DISCLOSURE         An arrangement for limiting rotational speed in a ver-tical shaft wind turbine has a central hub and spokes extending therefrom.  Spokes lying over each other support at their ends turbine blades placed concentrically around the turbine shaft.          Each turbine blade is pivotable about a vertical axle, and a leaf spring bundle is in each spoke placed between the turbine blade and the base of the spoke in order to set, when the turbine is at a rest, the turbine blade chord angle to a predetermined posi-tion.  In an unloaded state the centre of gravity of the leaf spring is located near and, as seen in the direction of rotation of the turbine, behind a plane through the symmetry axis of the turbine shaft and the pivot axle of the turbine blade.  The pivot axle of the turbine blade has such a position that the torque of the wind forces around the pivot axle is reduced to a minimum.     The spring bundle is dimensioned to exert a great resistance to deflection when the turbine rotates at operation speed so that chord angle of the turbine blade remains essentially unchanged.          At more higher rotation speeds beyond operation speed the spring bundle deflects more and more, resulting in a readjustment of the turbine blade in a direction limiting the rotation speed.
