摘要:
A method and apparatus for combining multiple components to form a coating material formulation in which one of the components is a resin, another component is a supercritical fluid employed as a fluid diluent, and, preferably,the third component is a catalyst. Two of the components are transmitted through separate flow paths to a first mixer (14) within which they are combined to form a mixture, and then the third component is added to the mixture in a second mixer (15) to form the coating material formulation for discharge by one or more coating dispensers or spray guns (12) onto a substrate.
摘要:
A flow regulator device for an analytical circuit, characterised by comprising: a fluid restriction (R) of defined characteristics related to the field of application of the analytical circuit, a direct-pressure regulator (2) positioned upstream of said restriction (R), a back pressure regulator (4) positioned downstream of said restriction (R).

The invention relates to an arrangement in connection with a gas mixer, which is arranged to form a mixed gas of oxygen and another gas to be mixed with it. To provide a simple and reliable arrangement, before the mixed gas is formed the oxygen is arranged to be supplied through both a mechanical adjusting means (4), and a mechanical and electronic flow-measuring means (5, 6). The other gas to be mixed with oxygen is arranged to flow through an electronic flow-measuring device (10). The flow of the other gas is arranged to be regulated by means of an electronically controlled regulating valve (9), whereupon the electronic flow-measuring means (6), the electronic flow-measuring device (10), and the electronically controlled regulating valve (9) are arranged to be operated by means of a control unit (13).

A valve positioner (10) for controlling a valve closure element is provided. The positioner includes a positioner housing with a plurality of fluid flow passageways in fluid communication with a fluid supply source and the valve closure element. The positioner housing is configured to receive a detachable spool manifold assembly (14). The spool manifold assembly is positioned adjacent the plurality of fluid flow passageways. The spool manifold assembly includes a reciprocally moveable spool (34) configured to selectively port fluid flow from the plurality of fluid flow passageways. The spool manifold assembly includes a diaphragm (48) connected to the spool via a flexible shaft (50). The diaphragm is in fluid communication with a transducer for receiving a fluid causing the diaphragm to expand or contract and thereby displacing the spool. The flexible shaft is radially elastic in order to minimize axial backlash between the diaphragm and the spool. The flexible shaft configuration minimizes the spool stroke.
摘要:
A continuous composite structure manufacturing apparatus which comprises a conveyor (25) or conveyors for conveying one or more fabric webs (43) along a conveying path. Each of the webs (43) is comprised of a reinforcing fabric, a non-woven fabric, or a layered fabric. The fabric web (43) is passed through the conveyor (25) so that it defines an enclosed foam injection zone (37). A foam injection system is provided for injecting foam into the foam injection zone (37) to form a foam core preform or a plurality of foam core preforms. One or more dies (35) are positioned along the conveying path, to shape each of the foam core preforms to a desired cross-sectional profile. The individual stringers or multiple, spaced-apart stringers are produced concurrently in a continuous production process.
摘要:
A method and apparatus for combining two components to form a coating material formulation in which one of the components is a "high volume" component comprising a resin including supercritical fluid as a diluent, and the other of the components is a "low volume" component such as a catalyst wherein resin and catalyst are transmitted through separate, but functionally related, flow paths to a mixer within which they are combined to form a coating material formulation which is then discharged by one or more coating dispenser or spray guns onto a substrate.
摘要:
A method of reducing drag in a fluid stream is disclosed. The method includes admixing the components of a drag reducer to form an incipient drag reducer and injecting the incipient drag reducer into the fluid stream wherein the drag reducer components are admixed at the site of the fluid stream.
