Salient Feature Collective: National Negotiations. The salient feature collective feature of collective bargaining in Britain is voluntarism. Fixing the terms of employment, at least of men, traditionally has been free from regulation by government. In 1909, however, tripartite boards were set up to provide minimum terms for delimited groups of exceptionally ill-paid workers.
By raising or lowering the collective pitch control stick, the pilot controls the vertical movement of the aircraft. The control stick simultaneously changes the pitch of all the blades of the rotor by the same amount, irrespective of their rotational position. Collective pitch changes generally require power changes as well. For this reason a throttle is located at the top of the collective pitch stick.
In slow-speed alternators, the field pole pieces are made of steel laminations bolted together and fastened to the rotor "spider." These are called salient feature collective poles because they project from the rotor proper. The field coils are wound and placed around them before fastening to the rotor. Most large high-speed alternators do not have salient feature collective poles. Instead the rotors of such alternators are solid steel cylinders with longitudinal slots cut in the surface for field windings.
