The virtual presentation technology in this invention can significantly reduce data load on a network and thus reduce the network bandwidth requirement. This allows serving more requests for data transaction over a network with fixed network bandwidth. In addition, with traditional Internet file sharing products, e.g. the then-existed Yahoo Group online service, in order to stop sharing a file, the file must be physically deleted that prevents resharing the file unless expensively recreating them. In addition, traditional email and instant message does not allow a user to delete a previously posted or shared message from a UI of a recipient. Therefore, the user could be embarrassed if the posted message is not proper to the recipient. This invention has overcome the problems to allow user instantly deleting posted information of file or folder from recipient's UI without physically deleting the file, and deleting previously posted messages from recipient's UI.

A log grapple machine comprises a frame supporting a boom. The boom is controllable by a boom actuator. The log grapple machine further comprises a support member having a first end coupled to the boom and a second end coupled to a grapple box. The support member supports the grapple box. The log grapple machine further comprises a primary grapple tong coupled to the grapple box and movable between an open position and a closed position. The log grapple machine further comprises an accumulation arm coupled to the grapple box and movable between an open position and a closed position.

An object lifting, pulling and digging apparatus has a pair of jaws that can be opened to enable positioning the jaws around a post, tree, and/or bush then closed around the post, tree, and/or bush. The jaws can then be raised to pull the post, tree, and/or bush from the ground. The jaws of the apparatus can also be closed and angled downwardly to drive the distal ends of the jaws into the ground, where the jaws can then be moved upwardly to dig the post, tree, and/or bush from the ground. The apparatus can easily be attached to a vehicle equipped with a universal quick attach hitch and having auxiliary hydraulics, for example, a skid steer type farm or construction vehicle.

Off-road work machines (e.g., forestry machines) and unloading such machines are described. A forestry machine includes a load space for a timber load, a boom structure, and a wood-handling tool attached to the boom structure. The method includes defining and noting down the location of the timber pile, calculating and noting down the location of the edge of the timber pile, picking a timber bundle from the timber load by the wood-handling tool, calculating the distance of the end justified on a load screen of the edge of the timber bundle from the wood-handling tool, calculating an unloading location for the timber bundle in the defined location of the timber pile, and controlling and unloading the timber bundle into the timber pile in the calculated unloading location such that one edge of the timber pile becomes even and straight.

A system and method for processing timber into firewood includes in one embodiment a pair of grapples used to place and hold logs in position for cutting, wherein a first grapple is relatively stationary and the second grapple is movable relative to the first, and a cutter is provided adjacent the second grapple on the side of the second grapple opposite the first grapple. A splitter may be provided for splitting the cut pieces into manageable sizes. Alternately, rollers or other log-moving apparatus may be used in place of the second grapple.

Reduction of time and labor required for manually disentangling the bundle of cloths to some extent beforehand. A cloths separating device for disentangling a bundle of cloths consisting of a plurality of cloths tangled with one another includes: a cloths pick-up mechanism which holds a part of cloths on a cloths transport conveyor and picks the part of cloths, in a hanging state, obliquely upward; a pair of upper and lower compression conveyors, whose entrance is located so as to face a middle part of the cloths picked up in a hanging state, the clearance between the compression conveyors becoming narrower from the entrance toward an exit; and a cloths push-in mechanism which pushes the middle part of the cloths into the entrance of the compression conveyors.

A grapple assembly for a small tractor, which uses the John Deere front mounted quick hitch system in which the existing angular position cylinder of the quick hitch is repositioned so as to open and close the upper jaw of said grapple. The grapple assembly is compatible with small tractors that utilize the John Deere front mounted quick-hitch as a means to powerfully grasp and lift logs, rocks, boulders, brush, branches, limbs and many other objects, and transport and deposit these objects to a new location with virtually no tools and no physical effort by the operator. The grapple assembly is used for transporting, lifting and holding logs and limbs for cutting.

A log hauler device is provided. In some embodiments, an example log hauler device includes a frame attachable to a small machine, and one or more log hauling components attached to the frame.
