摘要： Pools of all peripheral shapes of either above or below ground construction with single slope or flat bottoms when not in use may be equipped with a rigid structurally safe traversible completely dry surface deck or decks for domestic functions and to simultaneously insulate the surface of the water with which it is in contact but when pool is in use such a deck or decks are to be readily set at any depth in the pool until it or they become finally a false bottom by means of control by external low pressure hydraulic cylinders operated from the pool circulating system per medium of a single readily operable but safety positioned three-way valve.

摘要： Extension ladders constructed of pultruded fibreglass reinforced plastic for use in an high voltage electrical environment are improved when they do not have any metal components within the field of the induced electrical currents and to achieve the junction between the fibreglass reinforced plastic rungs requires separate molded fibreglass reinforced plastic external sleeves so adhesively bonded to the stiles and the pultruded hollow rungs to make the junction and also such sleeves are not to have any projections outside the outer boundaries of the stiles.

摘要： An appliance (10) for facilitating replacement of a waste bag by an ostomy patient comprises a base (12), an upright post (14) removeably seated in said base, and a slideable collar (16) supported on an abuttment (18) on said post. One end of the post (14) includes an opening which covers the stoma and collects any seepage during the replacement procedure. The face plate and adhesive sealing ring are preassembled on the post (14) and collar (16), along with any reinforcing tape (32), after which the post is removed from the base (12) and positioned over the stoma so that the preassembly can be guided as a unit into engagement around the stoma.
摘要翻译：一种用于促进由造口术患者更换废物袋的器具（10）包括基座（12），可移除地安置在所述基座中的立柱（14）和支撑在座位（18）上的可滑动轴环说帖子所述柱（14）的一端包括覆盖所述造口并在更换过程中收集任何渗漏的开口。面板和粘合剂密封环与任何加强带（32）一起预先组装在柱（14）和轴环（16）上，之后将柱从基部（12）移除并定位在造口上，使得预组装可以作为一个单元被引导成围绕造口的接合。
