Abstract:
A self-contained breathing closure for flasks and other containers that require gas exchange. An illustrative embodiment of the closure is comprised of a splashguard, an adaptor for attaching the closure to the container, a bellows element and a gas-permeable barrier element. The splashguard is intended to keep liquid contents under vigorous agitation in the container without wetting the gas-permeable barrier. The adaptor couples the closure to the container in a secure fashion. The bellows element allows for repeated changes in the internal volume of the container-closure system. The gas-permeable barrier allows desired gases to enter and leave the container while excluding small particles and/or microorganisms. The technology may be used with existing glass flask technology, or coupled to a plastic flask that may be configured for either single-use, or multiple-use.
Place And Bundle Method For The Manufacture Of Brush Seals
A long ribbon, composed of a multitude of fine wires, is placed at the requisite bristle angle onto a backing ring. A torch, welds the ribbon to the backing plate and simultaneously severs the ribbon--forming a first bundle of wires. The severed ribbon is repositioned, relative to the backing ring, adjacent to the first bundle, and the ribbon is again welded in-place and cut. The procedure of placement, welding and cutting is repeated until the backing plate (or the ribbon) has been repositioned over the desired length of the plate to achieve the requisite bristle array of the brush seal.
Bundle And Place Method For The Manufacture Of Brush Seals
A method for the production of brush seals, by first forming a linear array of contiguous, parallely aligned brush elements. The elements, each containing a multitude of bristles, are aligned in a resilient, linear support, in which the long axis of the bristles are parallel to each other. The resultant, resiliently supported array of brush elements is easily contoured to various arcuate shapes. For effecting a seal between the rotating elements of a turbine engine, the linear array is contoured in the form of a circular array, in which the free ends of the bristles in the array are joined to an annular backing ring.
A method for cutting the bristles which form the sealing ends of a brush seal, in which the tightly packed bristles are infiltrated with a liquid binder which is then hardened to form a rigid composite of bristles and binder. The resulting rigid composite can then easily be machined (cut or ground) without damage to the bristles. For metallic bristles, conventional fine line cutting methods such as single point turning or milling, are employed. Ceramic bristles, are machined by conventional bore grinding. After machining, the binder material may be immediately removed by melting or dissolution. Alternatively, the binder may be left on the bristles to provide protection during subsequent machining or handling procedures. The method provides accurate, smooth cuts while offering a combination of low cost and high production rates.
