Temperature-responsive Patents (Class 285/187)
  • Patent number: 11906096
    Abstract: A thermal expansion compensating device has a conduit with a first opening and a second opening for connection to a first pipe and a second pipe of a hot water system, respectively, the first and second pipes being formed by removing a section from a length of pipe of the hot water system. A pre-tensioning force is applied to the device to axially displace the first opening from the second opening until after connection of the openings of the pipes. A resiliently deformable pipe segment defines a portion of the conduit between the first opening and the second opening and is resiliently deformed to a tensioned position by the application of the pre-tensioning force. Once the hot water system is activated, the pipes axially thermally expand such that the first opening moves towards the second opening and the pipe segment moves from the tensioned position towards a rest position decreasing the stress on the device.

  • Publication number: 20020167165
    Abstract: A thermal insert connection in which a joint (16) located between a receiving component (12) and an insertable component (10) is sealed by applying a seal (17) which lies on a surface area (20a, 20b) which forms a groove (18) for receiving the seal (17). The seal (17) is first inserted after the thermal insert is assembled and cooled so that the seal is not subjected to thermal stress during the thermal insertion process.

  • Patent number: 6422610
    Abstract: A deformable fluid supply line for use on a semiconductor fabrication machine is described which includes a generally S-shaped expandable joint connecting between two straight conduit sections for providing full communication thereinbetween and for providing stress absorbing characteristics such that the expandable joint can be stretched or otherwise deformed by at least 2 cm without breaking connections with the two straight conduit sections. When the generally S-shaped expandable joint is provided with a length of at least 10 cm, a deformation of at least 3.5 cm can be tolerated by the expandable joint without causing failure or otherwise damages in the connections with the two straight conduit sections. The deformable fluid supply line can survive an earthquake of the magnitude of Richter 5 scale. The invention further discloses a method for connecting a deformable fluid supply line to a fabrication machine by using an S-shaped joint connected in between two straight conduit sections.

  • Publication number: 20020024217
    Abstract: A fluid coupling (60) for connecting fluid conduits includes a thermally sensitive member (30) and a coupling nut (40) which fit together for conjoint operation. The thermally sensitive member (30) has a resiliently expanded end (36) which engages a cooperating structure (14) on a fluid-carrying member (10) to retain it in place while permitting relative rotation. The thermally sensitive member (30) has a flange portion (34) that, when assembled, is in axial shear between the coupling nut (40) and the fluid-carrying member (10). When exposed to excessive temperature, the flange portion (34) softens, allowing the fluid-carrying member (10) to move and an in-line valve to close, thus shutting off the flow of gas. In another embodiment, the thermally sensitive member (84) is a bushing that is received within the plug body (80) of a quick-disconnect type coupling.

  • Patent number: 6173996
    Abstract: A method is used for interfacing materials of dissimilar thermal expansion in an X-ray tube. Initially, a first joint is identified, which has a first component to be received into a second component. Typically, the first component has a higher coefficient of expansion than the second component, so the purpose of the invention is to reduce the physical expansion of that component in the joint. A plurality of slots is introduced along the approximate axial length of a coupling member at the joint, to achieve the aforementioned purpose. The coupling member is provided between the two components, and has a thermal expansion rate greater than one component and less than the other component.
