Filed:

Feb 24, 1977

Appl. No.:

5/771800

Inventors:

Hubert J. Rosch - Plymouth MN

Assignee:

Kawasaki Motors Corp. U.S.A. - Santa Ana CA

International Classification:

B62M 2702

US Classification:

180 5R

Abstract:

A suspension system for a track driven vehicle such as a snowmobile, comprising a generally rectangular rigid suspension frame having longitudinal rails slidably supported on the inner surface of the track, and front and rear suspension assemblies for resiliently supporting the vehicle body. The front support assembly includes a weldment pivotally attached at its rear end to the frame, its front end being resiliently biased upwardly to support the body. The rear suspension assembly includes a transverse shaft carried by the body and a centrally disposed longitudinal compression spring for resiliently biasing the shaft upwardly relative to the suspension frame through a linkage effectively providing an increasing spring rate as the parts approach maximum excursion. The linkage includes pivotal components whose pivotal axes form a triangle which flattens as the body is displaced downwardly, and the change of altitude of the triangle is vectorially added to the component of the frame movement compressing the spring. The rate of that change increases rapidly as the parts approach maximum excursion.

Abstract:

A printed circuit processing apparatus includes a modular tank arrangement with each of the tanks receiving a printed circuit board to be processed on edge, or in other words vertically, and which guides the printed circuit board through the tank for processing without leaving marks or "tracks" on the sides of the board. The boards are driven by rollers on which the lower edges of the boards rest. The boards are held vertically through the use of a plurality of vertically spaced longitudinally extending wires. Spray nozzles are positioned on opposite sides of the boards and are simultaneously operated to generally equalize the pressure on the opposite sides of the board. The spray nozzles contain the necessary solutions for processing the boards, and the guide wires are small enough so that they don't leave any areas of the board unprocessed, nor do they leave "tracks". The modular tanks permit one or several operations in a continuous path with connecting sections between the modular tanks.
