  • Windmill construction
    Patent number: 4218184
    Abstract: A base is provided and a rotor is journaled from the base for rotation about a first upstanding axis. The rotor includes a plurality of vanes journaled therefrom for rotation about second axis spaced about and radially outwardly from the first axis and vane displacement control structure is operatively connected between the base and the vanes for proportionally angularly displacing the vanes relative to the rotor 180.degree. in one direction during each 360.degree. of rotation of the rotor in the opposite direction. The vanes are angularly displaced in optimum positions relative to the rotor and each other to develop maximum thrust by the vanes on the rotor responsive to fluid flow against the vanes from a predetermined side of the first axis.

    Patent number: 4218470
    Abstract: Novel cardiocirculatory analeptics are prepared, which are epinine esters as obtained by reacting epinine (N-methyldopamine) with branched-chain aliphatic carboxylic acids.

  • Tobacco harvesting method and apparatus
    Patent number: 4216642
    Abstract: Tobacco plants are harvested by having an operator ride a harvesting vehicle along a plant row so that as plants are successively cut from the ground by a cutter on the vehicle, the operator may grasp the severed plant and impale the same onto an upright stake likewise carried by the vehicle. As the stake becomes loaded with plants, the operator may remove the loaded stake from its holding socket on the vehicle and lay the same on a rearwardly disposed deck. He then replaces the loaded stake with an empty stake obtained from a supply thereof carried by the vehicle, and repeats the cutting, impaling and replacement steps until a sufficiently large accumulation of loaded stakes has been obtained on the deck. Thereupon, the deck is tilted to an inclined position so as to dump the plant-loaded stakes onto the ground in a pile, whereupon the cycle is repeated.
