摘要： A heat pipe has a pipe container and a fiber wick structure. The fiber wick structure is arranged on an inner wall of the pipe container, and the fiber wick structure has at least two kinds of fibers with different melting points. Furthermore, when the fiber wick structure is manufactured in a sintering process, the higher melting point of fiber provides a support force for the fiber wick structure coupled to the inner wall of the pipe container, and the lower melting point of fiber is melted in the sintering temperature of the pipe container to adhere to the higher melting point of fiber on the inner wall of the pipe container.

摘要： A flow regulator (1) having a regulator housing (2) in which, in a flow channel, an annular flow restrictor (5) made of elastic material is provided that is pushed onto a fastening post (4) and encircles this post. The post (4) has at least two fastening webs (6), oriented opposite a direction in which the elastic material is pushed on, whose free ends engage the flow restrictor (5) from behind in a securing manner. The flow restrictor (5) limits, between itself and at least one fixed part of the housing, a control gap whose flow cross-section can be modified by the flow restrictor (5), which deforms under the pressure difference that arises during flow. In the flow regulator according to the present invention the fastening webs (6) are fashioned as resilient webs that can be flexibly inwardly deflected. The flow regulator (1) according to the present invention can be manufactured economically and with a low cost, and is distinguished by its high degree of functional reliability.

摘要： An electrically conductive confined space ventilation conduit formed of a substantially rigid non-metallic conductive material, such as plastic, and a related process for ventilating an enclosure accessed by a manhole or other port. In one embodiment, the conduit has a pair of outer cylindrical sections and a central section having a cross-sectional shape of a crescent or a segment of a circle where it passes through a port to provide a minimum of obstruction for men and equipment passing through the port. Intermediate sections of varying cross-section connect the central section to the cylindrical outer sections so that the outer sections are offset from the axis of the manhole. The central section is preferably configured to obstruct no more than about 10 percent of a standard manhole opening, while causing either no air flow rate reduction, or a reduction of no more than about 10 percent as compared to the flow rate through a cylindrical conduit similar to said outer sections. The conduit is preferably formed of a conductive or electrically dissipative polyethylene polymer material to allow static electricity to be conducted from the conduit to ground. In a preferred embodiment, a connecting device for connecting the conduit to electrical ground is connected to the conduit. A grounding circuit kit and method of grounding the conduit is also disclosed.

摘要： Moving fluids are subjected to acceleration forces in turns, contractions, expansions and when flowing around bluff bodies. These forces can result in losses that are much larger than friction losses. For internal flow contractions, it is known that constant acceleration will eliminate pressure losses by balancing the forces that cause these accelerations with changes in static pressure. This disclosure teaches how to provide constant deceleration forces in expansions (diffusers) by maintaining a constant area to shear surface ratio, known as hydraulic diameter. Also taught, is how to design a turn vane array that has a hydraulic diameter equal to the upstream ducting diameter. Lastly, that these design techniques apply equally well to external flow regimes and a simple calculation demonstrates this method. Constant Acceleration Fluid Dynamics, results in ducting and bluff bodies that have no losses other than friction.

摘要： The invention relates to an arrangement (2; 2.2; 2.6; 2.7) to increase the thermal fatigue resistance of glass tubes (1; 1.2; 1.6; 1.7) flown through by fluid and pressure-loaded. This arrangement comprises a glass tube (1; 1.2; 1.6; 1.7), into which an interior component (3; 3.2; 3.6; 3.7) is inserted. The interior component (3; 3.2; 3.6; 3.7) can be designed as thin-walled tube (19; 19.2) or tubular component. In accordance with a first design example the cavity enclosed by the interior component (3; 3.2) is hydraulically connected with the interior (10) of the glass tube (1; 1.2). The wall thickness (s3) of the interior component (3; 3.2) is smaller than the wall thickness of the glass tube (1; 1.2) and the interior component (3; 3.2) is in the condition of being flown through by fluid at least partially free from a direct heat connection with the glass tube (1; 1.2). In accordance with a second design example the interior component (3.6; 3.7) increases the wall thickness of the glass tube (1.6; 1.7). In this case the interior component (3.6; 3.7) is touching the interior circumference of the glass tube.

摘要： A valve or ball reversal orifice provides provide a first flow restriction to a material flowing through the ball reversal orifice and a second flow restriction when the material reverses flow direction. The valve includes a housing having at least first and second walls that define a cavity therein. The cavity is configured such that a cross-sectional area of the cavity taken perpendicular to a longitudinal axis of the cavity decreases from the second wall to the first wall. A first port is provided in the first wall for allowing material to enter or exit a cavity, and a second port is provided in the second wall for allowing material to enter or exit the cavity. A flow restrictor, such as a ball, disposed in the cavity and is movable between a relatively large portion of said cavity and a relatively small portion of said cavity to provide different flow restriction depending on the direction of material flow through the cavity.
