Abstract

A bakeable high pressure-vacuum seal is provided in which an inductile sealing element having a butterfly shaped crosssection with protruding sharp edges at each of the four corners, is sandwiched between two ductile sealing elements, the sandwiched assembly then being compressed between the surfaces of the flange elements of a high pressure or high vacuum vessel to coin the ductile sealing element into the surface of the inductile sealing element as well as the surfaces of the flange elements.

Recycling coins from scrap

Patent Kumar, Nalin; Garcia, Jr., Manuel Gerardo; Lowe, Ronnie Kip

A material sorting system sorts materials utilizing a vision system that implements a machine learning system in order to identify or classify each of the materials, which are then sorted into separate groups based on such an identification or classification determining that the materials have a specified geometric shape. Such a system can sort monetary coins or other valuable metals from other forms of scrap.

Mechanical seal with high pressure high temperature secondary seal

Patent Hamilton, Eric; Nelson, Daniel

A secondary seal of a mechanical seal comprises an annular sealing gasket and backing plate surrounding a cylindrical sealing surface, all of which can be made of the same metallic material. The gasket is C-shaped in cross section, and is axially pressed during operation into a C-shaped groove formed in the backing plate, the groove being shallower and larger in inner diameter than the gasket, so that the gasket, when pressed into the groove, deforms radially inward and seals against both the backing plate and the sealing surface. The contact area between the gasket and sealing surface increases with pressure.more »« less

Titanium sealing glasses and seals formed therefrom

Patent Brow, Richard K [Albuquerque, NM]; McCollister, Howard L [Albuquerque, NM]; Phifer, Carol C [Albuquerque, NM]; ...

Alkaline-earth lanthanoborate sealing-glass compositions containing CaO, La.sub.2 O.sub.3, B.sub.2 O.sub.3, TiO.sub.2 and Al.sub.2 O.sub.3 in various combinations of mole-% are provided. These sealing-glass compositions are useful for forming hermetic glass-to-metal seals with titanium and titanium alloys that have a high aqueous durability for component or device applications requiring exposure to moisture, water or body fluids. Particular applications of the titanium sealing-glass compositions include forming glass-to-metal seals for lithium batteries and implanted biomedical devices (e.g. batteries, pacemakers, defibrillators, pumps).

Method of sealing a bipolar plate supported solid oxide fuel cell with a sealed anode compartment

Patent Carter, John David; Bae, Joongmyeon; Cruse, Terry Alan; ...

Methods of sealing a bipolar plate supported solid oxide fuel cell with a sealed anode compartment are provided. The solid oxide fuel cell includes a cathode, an electrolyte, and an anode, which are supported on a metallic bipolar plate assembly including gas flow fields and the gas impermeable bipolar plate. The electrolyte and anode are sealed into an anode compartment with a metal perimeter seal. An improved method of sealing is provided by extending the metal seal around the entire perimeter of the cell between an electrolyte and the bipolar plate to form the anode compartment.
