  • Patent number: 4630481
    Abstract: Method and apparatus to estimate the weight of the trees and logs in a stand of trees before harvesting to maximize the efficiency of aerial logging are disclosed. A hydrometer that has a chamber which accepts a small known volume core from the tree determines the density thereof. Statistical modeling permits weight estimations for the entire stand based on this density and other conventional information about the stand of trees.

  • Patent number: 4348863
    Abstract: A method and apparatus uses energy in an energy output system having a main power source, an energy transmission system and a mechanical output. A first portion of energy generated with the main power source is used to drive the mechanical output under operating conditions. The unused second portion of the energy is diverted to an energy storing means. The second portion of energy is then stored and regenerated on demand. The energy may be used directly to augment the energy requirements in the energy output system during peak periods. In a specific embodiment, a compressed air system is used for storing the energy not used in driving a mechanical output connected to the power source by an energy transmission assembly. The energy transmission in the energy output system is a hydraulic fluid transmission system. A hydraulic fluid diverting mechanism is used to maintain the flow of hydraulic fluid to the mechanical output and to the compressed air energy storage system.

  • Patent number: 4259834
    Abstract: In a machine for treatment of tree thinning residues and logging slash of the type having free-swinging flails pivotably connected to rotatable support structures at a pivot point, the improvement is made wherein each flail comprises a cutting blade containing the effective center of mass of said flail, and a plurality of side arms connected at one end of said cutting blade and having at the other end means for pivotal connection to said rotatable support structure, said means for pivotal connection being located on said rotatable support structure and the length of said arms being such that the distance R from the axis of rotation of said rotatable support structure to said pivot point, and the distance L from said pivot point to said flails effective center of mass having the following relationship:R/L=n/2where n is any integer from 1 to 5.
