Wake fields excited in a small gap of a vacuum chamber by ampere beams can have enough amplitude to heat the chamber. The electric component of these fields can be above the arcing limit. Usually flange connections in a vacuum chamber contain a vacuum gasket and an inner RF gasket. If a small gap occurs between the RF gasket and flange surface, wake fields can heat the flanges. The flanges are ...

This paper reports on the following: (1) Simple experimental investigations of pultruded fiber-reinforced plastic (PFRP) material behavior and tests of simple epoxied joints to verify and enhance the reported database; (2) cyclic tests of an attempted PFRP rigid beam-column connections; and (3) preliminary observations regarding the seismic-resistance worthiness of PFRP structures. These are si...

Abstract Welding of dissimilar metals is one the most substantial requirements industries and extensively used in engineering applications. Dissimilar friction crush welding between oxygen-free copper (C1020) aluminum (1145-H1) sheets with a thickness 1 mm was investigated this work using different flange edge heights (2, 2.5 3 mm) gaps (0.5 Cu-Al sheets. Tool rotational speed 1500 rpm feed rat...

A tool was developed to aid in ruminal insertion of abomasal infusion lines into dairy cows. The tool consisted of 2 pieces cut from polyvinyl chloride pipe. The first piece of pipe, the insertion tool, contained a groove that held the flexible plastic flange that is on the end of the infusion line. The insertion tool containing the flange was inserted into the ruminal cannula, through the sulc...

AIMS The Intraosseous Transcutaneous Amputation Prosthesis (ITAP) may improve quality of life for amputees by avoiding soft-tissue complications associated with socket prostheses and by improving sensory feedback and function. It relies on the formation of a seal between the soft tissues and the implant and currently has a flange with drilled holes to promote dermal attachment. Despite this, in...

Loss of continuity of the mandible leads to deviation of the residual segment towards the surgical site and alteration in muscle function. This results in facial asymmetry and malocclusion. A corrective device known as 'guide flange prosthesis' is indicated to limit this clinical manifestation. Guide flange prosthesis serves as a training device. It can successfully guide the patient to close t...

PURPOSE To delineate three-dimensionally the anterior and posterior surfaces of the lamina cribrosa, scleral flange, and peripapillary sclera, to determine the position and thickness of these structures within digital three-dimensional (3-D) reconstructions of the monkey optic nerve head (ONH). METHODS The trephinated ONH and peripapillary sclera from both eyes of three monkeys with early gla...
