Abstract: An air-adjustable shock absorber is pivotally connected at its ends to first arms of a front end of a back crank arm system, which are pivotally mounted to the vehicle chassis at the front and back of the same between the upper and lower runs of the endless track of the vehicle. The second arms of the front and back crank arm systems are connected to the front and back portion of the slides which engage the upper surface of the ground-engaging run of the endless track. The air pressure within the shock absorber unit biases the two crank systems in a direction so as to move the slides downwardly from the vehicle chassis. An air circuit system enables the driver to control the air pressure depending on the load carried by the vehicle. The crank systems are such that a greater proportion of the load is carried by the back of the suspension.

Abstract: A vehicle called a snow cycle vehicle due to its structural as well as operational resemblance with a motor cycle. This snow cycle distinctively includes a body of the bicycle or motor cycle type, a compact endless track and drive unit with the latter being longitudinally and resiliently pivotable and carrying the rear portion of the body, a steering having a steering reduction ratio between the handle bar and a front ski, and adjustable connection between the body and the endless track and drive unit, and a manually-adjustable suspension between the body and the endless track unit. This snow cycle vehicle also includes spring-biased suspension arms and a manually-adjustable spring resiliently supporting the rear portion of the body and the steering reduction ratio is produced by pivoting the ski through a crank arm about an axis parallel to the pivot axis of the handle bar.

Abstract: A machine adapted to produce efficient decanting and recycling of a liquid, such as an oil and grease solvent, and characterized by the combination therein of a laterally wandering upward flow and pumping of the liquid from close to the top surface of the latter.
