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
摘要:
A contour or profile of a bore of a locomotive traction-motor support bearing structure, where such profile preserves the currently center-loading of the upper load zone but moves inboardly the lower load zone to a more general central location. The profile of the bore for the support bearing, according to the invention, takes into account not only truck-axle bending due to locomotive weight, but also that from motor tilt through bearing clearances, and couple action on the axle from heavy radial loads on PE support bearing and adjacent axle gear. The bore is configured such that the upper surface is horizontal, but the lower surface slopes downwardly in the outboard direction at an angle based on a function dependent upon the three misalignment factors. In a preferred embodiment, the bore mid-section is defined as a frustroconical section of a cone with an altitude having a slope of substantially 1×M1 to the horizontal, and an apex angle of substantially arctan 2×M1, where M1 is the value of the misalignment factor associated with the locomotive load on the axle.

The invention is a magnetized tool for holding or retrieving nails. This is shown as a hammer having a magnet which may be on a removable cover or an extendable arm, mounted within the shaft or adjacent to the shaft of a hammer on the removable cover. The magnet is removable from the shaft to temporarily magnetize the striking face of the hammer so that a nail mail be held on the striking face temporarily. The magnet may be removably held to the hammer with a magnetic metal, such as another magnet which may be similar in size and shape and may be glued in place on the hammer. In another embodiment, the tool is a paint shield which may have bens to fit under walls. The shield may also serve to hold paint absorbing sheets to prevent spills and to clean up spills. The sheets may define a curving lip which curves upward to catch paint spills.

A method, apparatus, and computer instructions for providing addresses to clients. A request is received from a client for an address. A determination is made as to whether authentication information is present in the request. A verification process is performed using the authentication information if the authentication information is presenting the request. A determination is made as to whether the authentication information is authenticated. A privileged address is provided to the client in response to the authentication information being authenticated.
摘要:
An optical device, such as an electro-absorption modulator, has a waveguide formed onto a base. Electrodes adjacent the waveguide are used to selectively apply an electric field to the device in order to control the passage of light through the device. To prevent overheating of the device in a region near the point of optical entry, the electrode, which acts as a thermal conduit to dissipate heat from the waveguide is extended over the region. To prevent undesirable electrical contact between the electrode and the region, the normally electrically conducting contact layer between the electrode and the waveguide is removed in that region and replaced by an isolation dielectric.

A tire clamp for immobilizing a vehicle including a fixed bar having a generally L-shaped configuration. The fixed bar is comprised of a horizontal segment and a vertical segment. The horizontal segment is comprised of an inner portion and an outer portion. The inner portion has a plurality of sharpened teeth extending downwardly therefrom. The vertical segment has an inwardly angled lower portion. The fixed bar is positionable with respect to a tire with the horizontal segment disposed above and extending across the tire with the plurality of teeth abutting the tire and pointed thereat. A movable bar has an inwardly angled lower portion and is coupled with the fixed bar and is slidably mounted thereon. The movable bar is positionable with respect to a tire with both inwardly angled lower portions positioned against an exterior of the rim the tire is mounted on while the sharpened teeth remain oriented toward and abutting the tire. A lock prevents removal of the movable bar and movement with respect to the fixed bar.
