Принадлежит: Intex Recreation Corp.

A combination ladder assembly and pool includes a pool having a side wall and a support member positionable along an inner surface of the side wall of the pool. The support member may include at least one aperture. Additionally, the combination ladder assembly and pool further includes a ladder positionable along an outer surface of the side wall of the pool. The ladder may be removably coupled to the support member. The ladder further includes at least one leg having a first end and a second end and a plurality of steps. The plurality of steps may be coupled to the leg of the ladder between the first end and the second end of the leg. The ladder may be moveable between a use position, permitting ingress into the pool, and a storage position. When the ladder is in the use position, the leg of the ladder is supported by the support member. When the ladder is in the storage position, the ladder extends from the aperture of the support member to cantilever from the support member. 1.

An integrated single-piece exhaust system (SPEX) with modular construction that facilitates design changes for enhanced aerodynamics, structural integrity or serviceability. The SPEX defines splined or curved exhaust path surfaces, such as a series of cylindrical and frusto-conical sections that mimic curves. The constructed sections may include: (i) a tail cone assembly fabricated from conical sections that taper downstream to a reduced diameter; or (ii) an area-ruled cross section axially aligned with one or more rows of turbine struts; or both features. Modular inner and outer diameter inlet lips enhance transitional flow between the last row blades and the SPEX, as well as enhance structural integrity. Modular strut collars have large radius profiles between the SPEX annular inner diameter and outer diameter flow surfaces, for enhanced airflow and constant thickness walls for uniform heat transfer and thermal expansion. Scalloped mounting flanges enhance structural integrity and longevity. 1. An industrial gas turbine exhaust system , comprising:an inner case;an outer case circumscribing the inner case in spaced relationship relative to a centerline defined by the exhaust system;a plurality of struts interposed between the outer and inner cases;a turbine exhaust path defined between the outer and inner cases; andthe outer case defining an outer diameter ring with a lip extending radially inwardly therefrom into the turbine exhaust path on an inlet side of the outer case.2. The system of claim 1 , the outer diameter ring having:a chamfered entrance;the lip oriented axially downstream of the chamfered entrance, having a convex profile defining a radius that is oriented toward the centerline, the lip profile transitioning to a downstream diverging cone with respect to the centerline extending axially downstream within the outer case.3. The system of claim 2 , the outer diameter ring further comprising an annular notch interposed axially between the chamfered ...

Personal audio systems and methods are disclosed. A personal audio system includes a processor to generate a personal audio stream by processing an ambient audio stream in accordance with an active processing parameter set, a circular buffer memory to store a most recent snippet of the ambient audio stream, and an event detector to detect a trigger event. In response to detection of the trigger event, a controller may transmit, to a knowledgebase remote from the personal audio system, the most recent snippet of the ambient audio stream and associated metadata.
