Abstract: The present invention is directed to a functional chewing gum comprising a gum base and active ingredients boosting in mental clarity and concentration, wherein said active ingredients are selected among Shilajit, Ashwagandha, coenzyme Q10, L-Tirosine, Rhodiola, Bacopa monnieri, L-Alpha glycerylphosphorylcholine (alpha-GPC), Guayusa, Phosphatidylserine (preferably GMO free), and piperine (i.e. blackpepper extract). The present invention is also directed to a functional chewing gum comprising a gum base and active ingredients providing alleviation of fatigue and enhancement of energy, wherein said active ingredients are selected among Shilajit, coenzyme Q10, citrulline malate, Siberian Ginseng, L-Tyrosine, Ganoderma lucidum (Reishi), Hericium erinaceus (Lion's mane), Coconut Oil powder, Shilajit, Guayusa, Resveratrol and piperine (blackpepper extract).

Abstract: An improved four roller tree harvester head preferably includes a tower frame, a saw box, a delimb box, a four roller assembly, a slewing ring and a boom bracket. The saw box is mounted to a bottom of the tower frame and the delimb box is mounted to a top of the tower frame. Hydraulic hoses and electrical lines are routed through the boom bracket, slewing ring and tower frame to a hydraulic valve block. Hydraulic hoses may be attached to a rotary union. An actuation cylinder of the four roller assembly includes a linear positioning sensor, which provides an output to an electronic controller, which calculates a diameter of a tree. The four roller assembly includes at least one rotation encoder, which provides an output to the electronic controller about the length of a tree. An independent measurement wheel measures a length of the tree through the electronic controller.

Abstract: Indicia for providing a visual clue of the position of a vehicle on a race track preferably includes at least one of a first wall indicia strip and a first shoulder indicia strip being formed around the entire race track. At least one of a second wall indicia strip and a second shoulder indicia strip are formed starting at the beginning of the second turn and ending at the start/finish line. At least one of a third wall indicia strip and a third shoulder indicia strip are formed starting at substantially the half way point of the second straight and ending at the start finish line. At least one of a fourth wall indicia strip and a fourth shoulder indicia strap are formed starting at the beginning of the fourth turn and ending at the stop/finish line.

Abstract: Steering assemblies, methods and systems for powered or engine driven tandem axles used with work vehicles. A heavy duty work vehicle for rough terrain includes a tandem axle wherein engine power is transferred equally to both the front and rear ground following wheels of the tandem axle thru knuckle spindle steerable ends. A fluid system such as a hydraulic system unilaterally can control all four wheels or ground engagement tire positions of a single dual beam tandem or bogie assembly.

Abstract: A chain saw includes a chain formed into a closed loop about a drive sprocket and a support bar. A first piston is operable to move the support bar radially away from the drive sprocket, and a second piston is operable to limit such movement.

Abstract: A forester harvester has a house frame mounted on a base assembly and rotatable relative thereto about an axis of rotation. A boom is mounted on the house frame at a location radially offset from the axis of rotation. A cab is mounted on the house frame adjacent the boom and as forward as possible without protruding beyond the tail swing circumference of the house frame. A motor is mounted on the house frame rearward of the boom and the cab.
