摘要:
A commercial riding mower with a chassis built on a relatively rigid frame and having a number of operating systems such as the power plant, motive system, cutter drive system, and fuel storage and delivery system, each of which is accessible through a swing away panel, or hatch, for easy maintenance and repair without compromising safety of the operator or anyone in close proximity to the mower in operation, or impairing the structural integrity of the mower.

A method, system, and computer program product are disclosed for managing an application's persistent data across multiple different release versions of the application. A format for a memory area is defined wherein the persistent data will be stored according to a first release version of the application. The format is organized to permit the application running at different release versions to access the memory area. The memory area is accessed using the application that is running at a second release version. The memory area is divided into individually accessible sections. The format includes a template file for each section for each release version.

A semi-trailer has a surveillance system located within a hidden compartment of the semi-trailer. At least one external switch is located on an exterior of the semi-trailer and is electrically coupled to at least one subsystem of the surveillance system for controlling the at least one subsystem without controlling the entire surveillance system at once.

An improved wick-holder for mounting a felt lubricating wick is provided with a passive inertia-activated pump mounted for submersion in the axle-cap lubricant-reservoir at a level that ensures that for all levels of the reservoir, the pump inlet is submerged in the lubricant of the reservoir. In a first embodiment, the passive inertia-activated pump takes the form of a piston-type pump, while in a second embodiment, the passive inertia-activated pump takes the form of a diaphragm pump. In either embodiment, the inlet of the passive inertia-activated pump is submersed in the lubricant-reservoir, and the output of the passive inertia-activated pump is directed to the surface-interface between the felt wick and the axle journal surface-area to increase the lubrication thereof over and above that which normally ensues owing to the conventional capillary action of the felt wick. In a modification of the first embodiment, the piston pump is mounted to a splash sleeve forming part of the wick-holder and which is telescopingly received over the free end of the felt wick, with the output of the passive inertia-activated pump delivering the lubricant to the surface-interface between the felt wick and the axle journal surface-area via the hollow interior-volume of the splash sleeve and wick holder proper. The slosh pump of the invention may replace the wick assembly entirely, whereby the lubrication is achieved solely by the slosh pump of the invention.

An improved wick-holder for mounting a felt lubricating wick of a lubricating system for lubricating the axle journal surface supported in a support bearing of a traction motor used in a locomotive is provided with a plurality of oil-reservoir louver pockets or splash-cups molded or pressed into the wick holder which store oil from the time that the oil reservoir was full or near its maximum height and which store splashed oil during normal operational use, and delay the run off of the oil to increase the oil saturation of the wick housed within the wick holder. The oil reservoir pockets are located above the minimum serviceable oil level, and are designed to improve and increase oil saturation of the wick. As a result of the increased oil saturation, the wick are, therefore, capable of delivering increased amounts of oil to the axle journal area. The increased amount of oil saturation and reduced wicking height provide increased protection against traction motor support bearing failure if a locomotive is used with axle journal oil levels near the recommended minimum oil levels. Each reservoir pocket or splash cup is preferably louver-shaped, whereby during normal locomotive operating service, the splashing of oil in the bearing housing oil reservoir is collected and delivered to the lubricating wick. In a second embodiment, the reservoir pockets or splash cups are provided on a separate splash sleeve telescopingly mounted over, and to, the lower, free end of the central lubricating wick
