摘要： An in situ method for deriving the thermal properties of a layered structure represents physical layers by effective thermal layers. The method requires access to only one side of a structure and performs a series of tests wherein a periodic heat flux is applied to the surface of the structure. Each test employs a unique frequency, which is associated with an effective thermal layer of the structure. During the tests the temperature of the surface is monitored and a record of transient temperature is kept. A thermal model of effective layers is created based on the number of tests/frequencies available. The values of the applied heat fluxes are incorporated into this thermal model of effective layers. An optimization technique is used to find the thermal capacity and thermal resistance of the effective layers by best matching the predicted response to that of the measured transient temperature response.

摘要： A liquid chemical dispenser for an irrigation system comprises a removable supply container for the chemical which, in a first embodiment, comprises a valve for preventing spillage of the chemical during attachment of the container to the dispenser. This feature allows the container to be mounted in an inverted position on the dispenser without loss of its contents. In a second embodiment, the chemical container comprises a membrane which is pierced by a dip tube when the container is attached to the dispenser. A section of the dip tube produces an annular vent passage in the membrane around the dip tube to provide vacuum relief. The configuration of the containers substantially reduces the chance of inadvertent contact with the contents and the simple design permits the containers to be disposable.

摘要： A female hydraulic coupling member includes a bidirectional, pressure-energized probe seal for sealing between the body of the female coupling member and the cylindrical probe section of a male coupling member seated in the receiving chamber of the female member. In one embodiment, the pressure-energized seal comprises a first curved section which is oriented towards the external end of the receiving chamber in which it is installed and a second curved section oriented towards the interior end of the receiving chamber. The two curved sections are joined by a substantially straight back section. When the pressure of fluid within the coupling member is above the ambient fluid pressure, the first curved section is pressure-energized so as to increase its sealing effectiveness. When external pressure (e.g., the hydrostatic head) exceeds the pressure of fluid within the coupling member, the second curved section is pressure-energized so as to increase its sealing effectiveness. In another embodiment, the pressure-energized seal comprises a curved back section joining the first curved section and the second curved section. When the curved back section moves radially outward against a circumferential wall under the influence of fluid pressure within the seal, it effects a slight rotation of the first and second curved sections, thereby increasing their sealing effectiveness.

摘要： A probe seal for a female hydraulic coupling member has both internal and external pressure-energized seals. The outer wall or opposing ends of the seal have one or more pressure-energized seals for sealing between the body of the probe seal and the body of a coupling member in which the probe seal is installed. In certain embodiments, the generally ring-shaped probe seal has an annular fluid chamber in one or both end walls of the body of the seal. Hydraulic fluid under pressure may enter the annular fluid chamber and exert a generally radial force in response to a pressure differential. This radial force can act to increase the sealing effectiveness of the probe seal to the body of the female coupling member having such a probe seal. In “negative pressure” situations (i.e., when the ambient pressure exceeds the internal fluid pressure), seawater may enter an annular fluid chamber on the opposing end of the probe seal and similarly act to increase the sealing effectiveness of the probe seal to the body of the female coupling member. Annular, L-shaped, T-shaped or angled grooves in the inner wall of the seal form cavities and sealing projections that can be urged in an inward, radial direction by fluid pressure within an associated cavity to increase the sealing effectiveness between the body of the seal and the probe of a male hydraulic coupling member inserted in the receiving chamber of the female coupling member.

摘要： A plastic sheet product having a matte finish comprises a core layer of a thermoplastic polymer and at least one layer of a capstock composition which overlies, and is bonded to, at least one face of the core layer. The capstock composition comprises the same or different thermoplastic polymer and contains a plurality of discrete particles immiscible with and dispersed in the thermoplastic polymer of the capstock composition. The sheet product may be prepared by the co-extrusion of the thermoplastic polymer and the capstock composition, and in a particular embodiment, such co-extrusion may be conducted by means of a feedblock. In a particular embodiment, the thermoplastic polymer of the core layer and that of the capstock composition may be the same, such as in the instance of a methylmethacrylate-methylacrylate copolymer. Sheet products prepared in accordance with the invention exhibit improved post-processability and ease of surface maintenance, and may be fabricated into a variety of products including light diffusers, projection screens, and the like.

摘要： Male and/or female members of a hydraulic coupling have an internal poppet valve that is held in the closed position by a flat wire, helical compression spring. The spring is configured such that when the poppet valve is moved to its fully open position, the coils of the spring are completely compressed thereby forming a substantially smooth bore tube for the flow of hydraulic fluid. The flat wire, helical compression spring may also act as a valve stop, limiting movement of the poppet valve and providing the necessary resistance to move the valve actuator of a corresponding valve in a mating member.

摘要： A crown-type probe seal for a female hydraulic coupling member has one or more pressure-energized seals for sealing between the probe seal and the body of the coupling member which retains the probe seal. The generally ring-shaped probe seal has one or more annular fluid chambers in the wall of the seal's body. Each annular fluid chamber is open to the outer circumference of the probe seal. Hydraulic fluid under pressure may enter an annular fluid chamber through its opening an exert a generally radial force as a result of a pressure differential. This radial force can act to increase the sealing effectiveness of the probe seal both to the body of the coupling member retaining the probe seal and to the probe of a male coupling member inserted in the receiving chamber of the female member.
