    Abstract: Flexible seal assemblies having a relatively low torsional rigidity and high longitudinal flexure to thereby allow the flexible seal assembly to flex between adjacent components and maintain a seal, even when movement between adjacent components occurs, is described. In some embodiments, the flexible seal assembly includes one or more layers of metal matrix material, the metal matrix material being comprised of a plurality of short segments of thin wire arranged randomly and sintered together to form a semi-rigid sheet. The one or more layers of metal matrix material can be sandwiched between an upper casing and a lower casing of a metal alloy casing. In various embodiments, additional features are provided for helping to make sure the seal assembly stays together, such as spot welds formed through the seal assembly, an S-shaped casing, and a recess/protrusion feature provided on adjacent layers of metal matrix material.

    Abstract: A high pressure separator/accumulator that uses dual bellows is provided. The dual bellows are not mechanically linked but rather operationally coupled through a fluid medium. The high pressure separators includes a housing defining a first internal space. The housing is in fluid communication with a first fluid system and a second fluid system. A first bellows is coupled to the interior of the separator and defines a space with a variable volume. The space is in fluid communication with the first fluid system. A second bellows is coupled to the interior of the separator, generally opposed to the first bellows, and defines a space with a variable volume. The space is in fluid communication with the second fluid system. The two fluid systems, however, are isolated from each other by the separator. The housing is charged with a fluid medium that transmits force between the first and second bellows.

    Abstract: A sealed dual coaxial rotary shaft feedthrough device is provide. The device includes an inner shaft and a hollow outer shaft that is coaxial to encompass the inner shaft. The shafts include coupled drive and driven shafts. The coupling, which may be referred to as an eccentric coupling, causes the driven shaft to rotate with the drive shaft. The rotation is transmitted without breaking the seal by an eccentric portion of either the drive or driven shaft being nutatingly coupled to either a transition cap or transition cup. Nutatingly coupled means rotation of the shaft causes the transition cap or cup to orbit, but not spin, about the longitudinal axis. The nutation is transmitted by the transition cap or cup to the other of the shafts, which rotates.

    Abstract: An annular seal comprising a metallic ring having a cross section. The cross section includes an axially extending body portion having a radial width and an axial height. A spaced apart pair of sealing arms extend axially from the body portion, wherein each sealing arm includes a radially opposed arcuate sealing surface. The arcuate sealing surface may be convex, for example. The spaced apart pair of sealing arms are spaced apart a radial distance greater than the radial width of the body portion. A sealing system comprises a plurality of interconnected metallic rings wherein the body portion engages the sealing arms of an adjacent metallic ring.

    Abstract: A resilient metal seal that includes a PTFE jacket or liner capable of improving the sealing performance of the resilient metal seal and providing a near chemically inert surface to protect the seal from coming into contact with potentially damaging media is provided. In some embodiments, the resilient metal seal is an E-, U-, C-, or V-shaped resilient metal seal. A jacket made of PTFE or similar material can be included on the interior or exterior surface of the resilient metal seal. The jacket can include a locking feature to prevent against the jacket becoming dislodged from the resilient metal seal.

    Abstract: A metal O-ring is provided. The metal O-ring has a sidewall with an outer surface and an inner surface. The outer surface of the sidewall is machined to selectively thinning the thickness of the sidewall, such that the sidewall of the of the metal O-ring has a plurality of thicknesses equal to or less than a maximum thickness and equal to or more than a minimum thickness. Selectively thinning the sidewall by machining the outer surface allows for control of the elasticity of the metal O-ring. Controlling the elasticity of the metal O-ring, and potentially increasing the spring back, may provide for increased contract pressure at a sealing interface, which would facilitate sealing. The machined outer surface of the metal O-ring are generally machined to flat surfaces.

    Abstract: A one-way valve is provided. The one-way valve may be, for example, a check valve, a relief valve, or the like, which may be in the form of a poppet valve. The valve provides a housing with a through hole. The through hole has an upstream portion and a downstream portion. The upstream portion has a reduced diameter compared to the downstream portion. The housing contains a valve seat, which typically has a taper. A poppet, or valve member, moves within the through hole from a valve closed position and a valve open position. The poppet has a high pressure facing side and a low pressure facing side opposite the high pressure facing side. The low pressure facing side of the poppet engages an elastic member of a compression member that biases the poppet in the valve closed position. The high pressure facing side of the poppet engages a resilient metal seal in the form of an annular disc. The annular disc has a generally wavy or undulating shape. The outer ends of the resilient metal seal have a curve or arc shape and provide a seat interface that releasably engages the valve seat.

    Abstract: Several embodiments of the present technology are directed to actively controlling a temperature of a substrate in a chamber during manufacturing of a material or thin film. In some embodiments, the method can include cooling or heating the substrate to have a temperature within a target range, depositing a material over a surface of the substrate, and controlling the temperature of the substrate while the material is being deposited. In some embodiments, controlling the temperature of the substrate can include removing thermal energy from the substrate by directing a fluid over the substrate to maintain the temperature of the substrate within a target range throughout the deposition process.
