Abstract: A dyeing and welding process may be configured to convert a substrate into a welded substrate having at least some color imparted thereto via a dye and/or coloring agent by applying a process solvent having a dye and/or coloring agent therein to the substrate, wherein the process solvent interrupts one or more intermolecular force between one or more component in the substrate. The substrate may be configured as a natural fiber, such as cellulose, hemicelluloses, and silk. The process solvent may include a binder, such as dissolved biopolymer (e.g., cellulose). After application of a process solvent comprised of a dye and/or coloring agent, the substrate may be exposed to a second application of a process solvent comprised of a binder, which second application may occur before or after a process temperature/pressure zone, process solvent recovery zone, and/or drying zone.

Abstract: A track assembly for crawler tractors and the like wherein an endless track of individual rigid pad segments connected together by chain-type links is trained about a pair of track sprockets and supports the vehicle through a plurality of frame-mounted track rollers engaging the upper surface of the lower run of the track at longitudinally spaced points between the sprockets. The front or idler sprocket is rotatably mounted in a journal box which is slidable on the vehicle frame in a direction longitudinal of the track. The journal box is biased to yieldably resist rearward sliding movement by means of a resilient elastomeric bushing adjustably coupled between the journal box and the frame such that rearward sliding of the journal box tends to compress the bushing.

Abstract: A hydraulic system for mobile industrial equipment wherein the wheels or tracks of the mobile equipment are driven by a hydraulic transmission system having an engine-driven pump assembly, and wherein the hydraulic accessories mounted on the equipment are powered by a separate engine-driven hydraulic pump which draws its fluid from the hydraulic transmission pump assembly, and particularly the charge pump component thereof.
