摘要： A seal system for a pressure vessel which includes a substantially rigid outer shell with at least one opening therein, an inner liner disposed within the outer shell against the inside surface thereof, an opening aligned with the opening of the outer shell and a boss disposed in the opening of the outer shell. The boss includes a neck portion for fitting in the opening of the outer shell, a flange portion extending outwardly from one end of the neck portion and having an upper surface and a lower surface, and a generally cylindrical hollow substantially aligned with the outer shell opening and having an inwardly projecting annular shoulder. The lip segment of the liner extends radially inwardly under the lower surface of the flange portion of the boss and then upwardly into the hollow of the boss, along the interior wall of the hollow until a portion of the lip segment rests on the shoulder.The seal system includes an attachment or coupling device having a generally cylindrical, downwardly extending lower insert section. The lower insert section includes an annular bottom wall in which is formed an annular recess opened downwardly. An upper head section is formed at the upper end of the insert section and includes a radially extending flange. The insert section is dimensioned to fit in and be received by the hollow of the boss above the shoulder. The seal system also includes a resilient O-ring for disposition in the recess of the insert section of the coupling device to protrude from the recess a sufficient distance to contact and seal against the lip section of the liner resting on the shoulder of the boss hollow, when the insert section is fitted into the hollow.

摘要： In a quick connector for piping 10 for detachably connecting a male member 12 to a female member 11, an O-ring 15 is interposed between the female member 11 and the male member 12 so as to form a seal therebetween, and the O-ring 15 is subjected to a low-friction treatment so that the O-ring can be moved in a direction of an axis of the quick connector 10 by a pressure of an employed fluid.

摘要： A filter element is made of a first filtering member, and a second filtering member that is arranged on a downstream side of the first filtering member and is impregnated with an oil. The first filtering member consists of a downstream wet layer that is impregnated with the oil, which is transferred by contact to the second filtering member, and an upstream dry layer that is not impregnated with the oil. A density of the first filtering member may be set smaller than that of the second filtering member.

摘要： An air filtering material for air cleaning is formed of a nonwoven fabric of hollow chemical fibers having longitudinal interior holes containing an oil. The hollow chemical fibers have randomly formed minute cracks and/or fissures formed through the walls of the fibers. The cracks and/or fissures have a width of the order of 1 ìm . The oil gradually exudes from within the longitudinal holes through the cracks and/or fissures to wet the outer surfaces of the hollow chemical fibers to enhance the filtering ability of the air filtering material by binding dust particles by the sticky oil.

摘要翻译： 用于空气净化的空气过滤材料由具有含有油的纵向内孔的中空化学纤维无纺布形成。 中空化学纤维随机形成通过纤维壁形成的微小裂纹和/或裂缝。 裂缝和/或裂缝的宽度约为1μm。 油通过裂缝和/或裂缝从纵向孔中逐渐渗出，以润湿中空化学纤维的外表面，以通过粘性油粘结灰尘颗粒来增强空气过滤材料的过滤能力。
