  • Patent number: 7310877
    Abstract: The present invention relates to a method of producing the sensors for monitoring corrosion of heat exchanger tubes in a thermal power plant. The sensor is made of the tubes taken out from actual heat-exchanger. As a result, the sensor not only has the same material as the actual heat-exchanger tubes, but also has the same surface state where it contacts the working medium. Therefore, a serious technical difficulties have been solved that the sensor made by the prior art can't measure different corrosion states of actual heat-exchanger tubes, that the corrosion rate measured is different from the corrosion rate of actual heat-exchanger tubes, and that the cost of anti-corrosive treatments is high . By use of the sensor made by the present invention, the different corrosion states of actual heat-exchanger tubes can be measured, not only the rate of uniform corrosion of actual heat-exchanger tubes can be measured but also the rate of localized corrosion of the heat-exchanger tubes can be measured.

    Abstract: A method for manufacturing a driveshaft assembly takes advantage of the asymmetrical nature of the driveshaft tube and end fittings to reduce the initial imbalance of the driveshaft assembly. The method includes the initial steps of providing a driveshaft tube having a heavy side and providing an end fitting having a heavy side. The heavy side of the end fitting is aligned so as to be opposite the heavy side of the driveshaft tube. Finally, the driveshaft tube and the end fitting are secured together. The dimensional characteristics of the driveshaft tube and end fitting improve the balancing capability of the driveshaft assembly by permitting levels of imbalance of the driveshaft assembly to be lowered and better-managed.

Welding of the formed transversal frame with one of the two longitudinal wires is performed while the formed transversal wire is still restrained by the action of the press (38) at the formation location. Welding with the second longitudinal wire is performed at the next production step, simultaneously with the welding of the next transversal frame with the first longitudinal wire, at the formation location.

  • Patent number: 6134779
    Abstract: An improved high performance aluminum connecting rod and a method for manufacturing such a connecting rod are disclosed, the connecting rod being capable of carrying particularly high compressive loads with a substantially reduced deformation resulting from such high compressive loads. In the preferred embodiment, the connecting rod of the present invention is made of an extruded bar stock forging made of an aluminum alloy material which is forged and machined to make the connecting rod. The connecting rod of the present invention has a substantially increased compressive yield strength as well as a substantially increased tensile yield strength. This increase in the compressive yield strength of the connecting rod of the present invention effectively prevents bending of the connecting rod beam, elongation of the wrist pin bore, and a marked deterioration in the roundness of the bearing housing bore.

  • Patent number: 5759468
    Abstract: A cube corner article and method of manufacturing the article from a series of unitary substrates. A plurality of pins are assembled to form a mold having an array of cube corner elements on a surface. Then, a replica of the cube corner element array is produced in a substrate suitable for forming retroreflective surfaces. Portions of the replica substrate material are removed. The removal of these portions forms at least one cavity bounded by side walls in the replica at a depth at least that of the cube cube corner elements. The replica is replicated to produce an additional directly machinable substrate suitable for forming retroreflective surfaces having at least one raised section having sidewalls at a height at least that of the cube corner elements. At least one raised section is directly machined to form an array of cube corner elements.

  • Patent number: 5661889
    Abstract: A process for producing a container and closure assembly includes molding a preliminary container including a closed bottom portion, a body portion and a shoulder and neck portion. The shoulder and neck portion is separated from the body portion. An open ended second container is formed from the body portion, the second container having a rim at its open end and an encircling wall. The open end of the second container is then closed with a closure comprised of a cap and a cap liner. The cap liner has a weakened portion adapted to be broken by the cap. The cap or the cap liner are formed from the shoulder and neck portion of the preliminary container.

  • Patent number: 5577323
    Abstract: It is an object of the invention to provide a method of manufacturing an inner ring for a rolling bearing in which the directions of the metal flows of the inner ring can be made substantially parallel to the shape of the race surface of the inner ring to thereby manufacture a rolling bearing inner ring having an enhanced durability. In the manufacturing method, a cylindrical steel billet 1 (shown in FIG. 1 (a) including a large number of metal flows 2 formed in the axial direction of the section thereof is held and upset by and between first upper and lower metallic molds 4a and 4b each having a transfer surface 3 for the race surface of the inner ring and, at the same time, recesses 6 are formed in the upper and lower plane portions of the cylindrical steel billet 1 respectively (shown in FIG. 1(c), next after the upper and lower shoulder portions of the recesses are respectively held by and between second upper and lower metallic molds 9a and 9b (shown in FIG.

  • Patent number: 5566449
    Abstract: A connecting rod as a shaft clamping member includes a rod member and cap, each of which has mating faces at circumferentially opposite ends of a semi-circular recess and which are fastened to each other by bolts by matching the opposed mating faces to each other to define a crank pin hole by the two semi-circular recesses. The rod member and the cap are forgings formed from an aluminum alloy and simultaneously produced by forging powder preforms of the rod member and cap in a cavity having the desired shape of the connecting rod. After forging, the opposed mating faces have an infinite number of recesses and projections which are formed from the flow of the material during the forging and which are in a matched and fitted relation to each other. Thus, any misalignment between and in a direction parallel to the mating faces can be prevented to avoid the generation of a situation that only the rod member receives a stress. This achieves a prolongation in the life of the connecting rod of the aluminum alloy.

  • Patent number: 5231749
    Abstract: A method of making design models allowing for CAD data verification of interior and exterior styled surfaces comprising the following steps. Initially, the interior and exterior surfaces of the proposed design are mathematically modeled. A series of separable parts of said design are defined. At least one bench mark plane is provided within the interior and exterior surfaces of a first part of the design. An exterior surface is shaped on an exterior portion of the first part of the design. Likewise, an interior surface is shaped on an interior portion of the first part of the design. The interior portion and the exterior portion are separated from each other at the bench mark plane when the interior portion is formed. The interior portion and exterior portion are assembled together at the bench mark plane. Finally, the separable parts or modules are assembled together at the boundaries. The method further allows for the disassembly of particular modules and their modification in holding fixtures.

  • Patent number: 5223051
    Abstract: A process for producing multipiece complementary tooling castings is disclosed in which hollow internal surfaces are cast in a mold having a soft, low strength sand core piece to define such hollow portions and external surfaces are cast against hard, resin-bonded sand mold surfaces. The castings are removed from their respective molds while still warm and nested and pressed together to bring their working surfaces into conformance with each other. The result of this practice is a set of tool pieces that require little machining and display high accuracy in their as-cast condition.
