Abstract: Internal valve apparatus are described. An example internal valve includes a body having a valve seat disposed in a fluid flow passageway between an inlet and an outlet. A flow control member is operatively coupled to the body and movable between a first position to engage the valve seat to restrict fluid flow through the valve and a second position to move away from the valve seat to allow fluid flow through the valve. A removable actuator is coupled to the body and operatively coupled to the flow control member to cause the flow control member to move between the first and second positions. A portion of the removable actuator is cantilevered in the fluid flow passageway between the inlet and the outlet when the removable actuator is coupled to the body.

Abstract: A tubeaxial fan (10) broadly including a cylinder (12), a propeller (14) rotatably supported in the cylinder (12), and a drive assembly (16) operable to rotate the propeller (14) is disclosed. The propeller (14) includes blades (28,30,32,34,36,38) each having an inventive blade design. The inventive blade design presents a chord length (C), a stagger angle (βe), and a camber height (δc) that vary along each of the blades as shown in TABLE 1. The inventive blade design presents an external surface of each of the blades having a shape defined by the relative positioning of a plurality of coordinates contained in at least nine cross-sections (e.g., the blade (28) includes cross-sections (44,46,48,50,52,54,56,58,60)). The cross-sections (44,46,48,50,52,54,56,58,60) of the illustrated blade (28) have the corresponding plurality of coordinates listed in TABLE 2. The drive assembly (16) incorporates an inventive design that presents, among other features, a cover dimension DC of the bearing cover (72) of less than about one-sixth the propeller diameter (δ), and tapering end sections (76a,76b) on the belt cover (76). A preferred alternative embodiment is also disclosed in the fan (210) including support plates (212a,212b) having a plate width (WP) between about one-tenth and one-seventh of the axial length of the cylinder (212).

Abstract: An example loading regulator having an internal relief valve apparatus includes a body having a loading diaphragm disposed between a first casing and a second casing. The first casing and a first side of the loading diaphragm define a first chamber and the second casing and a second side of the loading diaphragm define a second chamber. A relief valve assembly is coupled to the loading diaphragm. The relief valve assembly includes a relief valve seat having an aperture that forms a passageway to fluidly couple the first chamber and the second chamber and a relief valve plug movably coupled to the relief valve seat. The relief valve seat is to move relative to the relief valve plug to a bleed position to allow the flow of fluid between the first chamber and the second chamber in response to an outlet pressure substantially greater than a pressure at which the loading regulator enters a lock-up condition.

Abstract: A ventilation assembly (10) for venting fluid impregnated fumes and separating the fluid for collection is disclosed. The ventilation assembly (10) broadly includes a curb (12), a curb cap (14), a fan (16), and a disposable grease collection cannister (18) removably coupled to the fan (16). The fan (16) generates an airstream and separates any grease entrained in the airstream from the airstream. The separated grease is collected in the cannister (18). The entire cannister (18) can be quickly and cleanly removed, disposed of, and replaced. The cannister (18) broadly includes an open top receptacle (52) for receiving the grease, an absorbent core (54) in the receptacle (52) for absorbing and storing the grease, a funnel (56) for directing the grease into the core (54), and a lid (58) for covering the open top and removably coupling the cannister (18) to the fan (16) for removal therefrom without contacting the receptacle (52).
