12 Feb 1979TL;DR: An electrical connector including a socket having an axis, a metal bellows connecting the socket to a support for adjustment of the axis in response to insertion within the socket of an axially misaligned plug or connector, the metal Bellows further being an electromagnetic radiation shield between the plug and the support as discussed by the authors.

TL;DR: In this article, the authors present a comprehensive overview of the history of vacuum tube and vessel construction. But they focus on the preparation of vacuum tubes and vessels, and do not address the design of these components.
Abstract: Contents: Cleaning of Electron Tubes and Vacuum Components. Electroplating and Stripping. Heat-Treating and Brazing. Induction Heating: Radio-Frequency Heating, Bombarding. Glass-to-metal Seals. Metal and Ceramic Bending. Tube Laboratory Procedures. Heater Design and Preparation. Nickel Bases for Oxide-coated Cathodes. Oxide-coated Cathodes General. Getters and Getter-ion Pumping. Cryopumping. Ultrahigh Vacuum. Vacuum Techniques, Design Procedures, and Construction of Vacuum Tubes and Vessels. Gas Filling of Tubes. Metal Bellows. Procedure for Assembling Tubes. Leak Detection. Vapor Pressure. Glossary.

28 May 2004TL;DR: In this paper, an implantable artificial sphincter system provides long-term adjustment via transcutaneous energy transfer (TET), minimizing invasive adjustment through adding or removing fluid via a syringe.
Abstract: An implantable artificial sphincter system provides long-term adjustment via transcutaneous energy transfer (TET), minimizing invasive adjustment through adding or removing fluid via a syringe. An infuser device provides bi-directional fluid transfer via a flexible conduit to a sphincter band, such as a gastric band, by a combination of thermodynamic actuation and a piezo-electrically disengaged drum brake assembly that thereby achieves a desirable small volume device. A propellant within a propellant cavity surrounds a metal bellows accumulator biased at body temperature to either expand or collapse the bellows accumulator with the opposite direction of movement effected by a thermal element that heats in combination with a negatively-biased propellant or cools in combination with a positively-biased propellant. A drum brake assembly locks the metal bellows accumulator in place between adjustments by thermodynamic actuation by activating piezo-electric stack actuators that disengage calipers from a brake drum attached to the bellows accumulator.

12 May 2005TL;DR: A remotely controlled gastric band system that is practically immune to external magnetic fields, such as from a Magnetic Resonance Imaging (MRI) machine, incorporates a bi-directional pump and fluid reservoir to adjust fluid volume for hydraulic control of a gastric bands as mentioned in this paper.
Abstract: A remotely controlled gastric band system that is practically immune to external magnetic fields, such as from a Magnetic Resonance Imaging (MRI) machine, incorporates a bi-directional pump and fluid reservoir to adjust fluid volume for hydraulic control of a gastric band. A piezoelectric driver (e.g., rotary actuator, linear actuator) selectively compresses and expands a metal bellows hermetically sealed within a biocompatible and nonferromagnetic enclosure or case such as titanium. Directly sensing a position of the metal bellows yields an accurate reading of volume contained therein, allowing for closed-loop control of the gastric band.
