摘要:
A contaminant removal system is disclosed for selectively removing contaminants from a fluid stream. The contaminant removal system has a catalytic reactor of the type that is susceptible to deactivating agents, and is configured to remove contaminants from a fluid stream. The contaminant removal system has a first adsorbent device positioned upstream, with respect to the fluid stream direction, of the catalytic reactor, that is configured to chemically bind with and remove the deactivating agents from the fluid stream. The contaminant removal system can have a second adsorbent device positioned downstream, with respect to the fluid stream direction, of the catalytic reactor. The second adsorbent device is configured to remove undesirable byproducts that may be generated when the catalytic reactor removes contaminants from the fluid stream.

A hybrid airfoil for a gas turbine engine is provided that includes a body and a panel. The body has a first side and a second side orientated opposite the first side. The first and second sides extend between a tip, a base, a leading edge and a trailing edge. The body includes a plurality of cavities disposed in the first side of the body, which cavities extend inwardly toward the second side. The cavities collectively form an opening. At least one rib is disposed between the cavities. A shelf is disposed around the opening. The panel is attached to the shelf first mounting surface and to the rib, and is sized to enclose the opening. The panel is a load bearing structure operable to transfer loads to the body and receive loads from the body.

A method of making a passenger conveyor handrail includes forming a drive member having a plurality of longitudinally spaced drive surfaces. The drive member has a longitudinal stiffness for maintaining a desired spacing between the drive surfaces. The drive member is inserted into a molding device. A gripping surface portion of the handrail is formed using the molding device such that the gripping surface portion and the drive member are secured together. Another method includes forming a belt drive member having a plurality of teeth that establish a plurality of longitudinally spaced drive surfaces. The belt has a longitudinal stiffness for maintaining a desired spacing between the drive surfaces. Each of the teeth extends across an entire width of the belt. The belt is secured to a gripping surface portion of the handrail.

A passenger conveyor (20) includes a handrail assembly (30) comprising a handrail (32) having a plurality of co-extruded polymer materials (34, 36). In one example, an outermost portion (34) establishes a passenger gripping surface (38). One example includes an extruded soft, low cost polymer in the middle of the handrail cross section to reduce cost and weight. A disclosed example includes a toothed driving surface (40) on an inner side made of a selected one of the polymer materials (34, 36). In one example, the driving surface (40) and the gripping surface (38) comprise the same polymer material.

A passenger conveyor handrail (30) includes a sliding layer (40) that is non-woven in some examples and non-fabric in other examples. A first polymer material is used to establish a body portion (32) of the handrail (30) to provide, for example, a gripping surface (34). The sliding layer (40) is secured to a surface (38) of the handrail (30) to cover at least a portion of that surface to meet the needs of a particular situation. Disclosed examples include a variety of configurations and a variety of techniques for applying such a sliding layer (40) to a handrail (30).

摘要:
The seat of a suction valve of a reciprocating compressor is modified to limit the area in which an annular oil film can be established between the valve and the valve seat. The seat is configured to limit the oil film from 3% to 33% of the total inlet port opening. In a modified embodiment gas at discharge pressure exerts an opening bias to the suction valve at the end of the discharge stroke.

The present invention relates to a two-component acrylic modified polyester adhesive. Said adhesive comprising a first component having an acrylic modified polyester and about 0.1% to about 0.5% by weight of a peroxide, and a second component comprising an organometallic acid salt in a polymerizable organic monomer. In addition, a method of using said adhesive is disclosed.
