Abstract:
A method for fabricating a heat pipe structure in a radiating plate is provided. A tunneling means is used to form a plurality of radiating channels in the radiating plate. Each of the plurality of radiating channels has only opening. Then, only one of the openings of the radiating channels is not sealed, while sealing the other openings of the radiating channels. Working fluid is injected into the radiating channels via the reserved opening. Radiating channels is vacuated and the reserved opening is sealed.
Abstract:
A sliding door repair apparatus to facilitate horizontal sliding movement of a preinstalled sliding door having one or more defectively sliding wheel(s) being supported on a lower track. The repair apparatus includes at least one vertically adjustable rigid bracket attached to the sliding door and at least one repair roller attached to the bracket such that the repair roller is situated in moveable contact with and atop the lower track and supports at least a portion of the weight of the sliding door thereby transferring the weight from the defective wheel(s) within the door thereby facilitating the sliding of the door along the lower track without the necessity of removing or disassembly of the sliding door and without having to remove, replace or repair the defective wheel(s).
Abstract:
A method for repairing structures uses an accurate measurement of the part to be repaired and the structure into which it fits. The method allows for a digital measurement of features of the part and the structure, and eliminates tedious and inaccurate hand-measurement methods previously used. The method is primarily applicable to one-of a-kind parts requiring exact measurements, because of the unique shape that a part may assume when it is subject to stress and strain over time and many cycles of use.
Abstract:
A method is disclosed for reconditioning blades for turbo-machinery that have a material deficiency resulting from wear and tear, damage, or dimensions that are smaller than specified, in which material is removed, at least from parts of the blade, and is replaced with new material. The actual geometry of the blade is measured at certain specific points and is stored. The desired geometry, or the desired profile in its desired position, is determined via data processing technology. The desired geometry is compared with the actual geometry, and in cases of significant deviations in position, is adjusted to coincide with the actual geometry. The adjusted desired geometry is mathematically reduced by a defined amount of coating to be removed. The calculated net geometry is actually produced via the removal of material, at least over part of the blade, and new material is applied to the finished net geometry, until the desired profile is achieved.
Abstract:
A method and apparatus for repairing an automobile wheel is provided. The apparatus includes a rotatable center shaft assembly. An anchor anchors a wheel to the center shaft assembly. The center shaft assembly being rotatable so that anchoring the wheel rotates the wheel with the anchor. A centering device is disposed about the center shaft assembly between the center shaft assembly and the wheel for centering the wheel about the center shaft assembly.
Abstract:
An improved mounting arrangement for a knife to a disc for use on a rotary disc cutter that eliminates the need for a threaded connector and the associated nut is disclosed. It also provides a positive retention method on the top side of the disc. In addition, it provides a method of removing the knife from the disc without the use of wrenches, simply requiring a tool for prying, such as a screw driver. A further feature is a low profile retainer that does not need to be protected by a wear protector.
Abstract:
A method enables replacement of a gas turbine engine combustor liner. The combustor has a combustion zone formed by inner and outer liners. A plurality of cooling features are formed by overhanging portions of the inner and outer liner liners. The method comprises cutting through at least one of the combustor inner and outer liner aft of an overhanging portion, wherein the portion of the combustor liner upstream from the cut remains coupled within the combustor, removing the portion of the combustor liner that is aft of the cut, and installing a replacement liner within the combustor such that the replacement liner extends aftward from the portion of the combustor liner that is upstream from the cut.
Abstract:
A heat dissipating apparatus (10) includes a heat pipe (20) and a heat sink (30). The heat sink is made by die-casting, and includes a chassis (32) and a plurality of fins (34) extending upwardly from the chassis. The heat pipe is U-shaped, and is embedded in the heat sink in intimate contact with the chassis and the fins. The heat pipe includes a first end (12) and a second end (14). The first end is partially embedded in the chassis of the heat sink, for transfer of heat from the chassis to the first end by way of vaporization of working medium in the heat pipe. The second end is embedded in upper portions of the fins, for transfer of heat from the heat pipe to the fins by way of condensation of the vaporized working medium.
Abstract:
A heat pipe heat spreader is provided having a substantially L-shaped enclosure with an internal surface and a plurality of post projecting from the surface. A working fluid is disposed within the enclosure, and a grooved wick is formed on at least a portion of the internal surface. The grooved wick includes a plurality of individual particles having an average diameter, and including at least two lands that are in fluid communication with one another through a particle layer disposed between the at least two lands that comprises less than about six average particle diameters. A method for making a grooved heat pipe wick on an inside surface of a heat pipe container a layer of sintered powder between adjacent grooves that comprises no more than about six average particle diameters.
Abstract:
The invention provides a method of replacing a worn wear strip located between a rail and a retaining plate, the method comprising positioning a new wear strip adjacent the worn wear strip, securing a clamping apparatus to the rail adjacent the new wear strip opposite the worn wear strip and urging the rail in a direction from the clamping apparatus to the retaining plate until the clamping apparatus abuts the retaining plate, the new wear strip pushing the worn wear strip from its position between the rail and the retaining plate. The invention also provides a clamping apparatus configured to be secured to a rail, the clamping apparatus comprising first and second flanges and a spacer, the first and second flanges and spacer all having at least one bolt hole therethrough, and at least one bolt inserted through the at least one bolt hole.
