摘要： A system and method for connecting two flexible containers is provided, in particular for the environmentally sealed connecting of two open ends of tubular films. The method has at least the following method steps of: everting a first open end of a first flexible container over a first ring; everting a second open end of a second flexible container over a second ring, subsequently inserting the first ring through the second ring into the inside of the second flexible container; subsequently aligning, in a parallel and coaxial relationship, the rings in relation to one another; and abutting the rings with the ends clamped in between them.

摘要： A coupling for mine ventilation conduits comprising a first tubular conduit having a flared end portion for receiving an end portion of a second tubular conduit, at least one of the conduits having an elongate flexible strap attached thereto having a length sufficient to reach the other tubular conduit. A resilient compressible strip is placed between said first and second tubular conduits around the periphery of the end position of the second tubular conduit. The coupling also includes a device for tightening the flexible strap length and for holding the strap in a tightened position, the device being secured to one of said conduits and providing for tightening of said strap to draw said tubular conduits together to compress the resilient strip between the flared end portion of the first conduit and the end portion of the second conduit to thereby provide a substantially air tight seal between said conduits.
摘要翻译：一种用于矿井通风管道的联接器，包括第一管状管道，其具有用于接收第二管状管道的端部的扩口端部分，至少一个管道具有连接到其上的细长柔性带，其长度足以到达另一个管状管道。弹性可压缩条被放置在围绕第二管状导管的端部位置的周边的所述第一和第二管状导管之间。联接器还包括用于收紧柔性带长度并将带保持在紧固位置的装置，该装置被固定到所述管道中的一个，并且提供用于紧固所述带以将所述管状管道拉紧在一起以将弹性带压缩在第一导管的扩口端部和第二导管的端部，从而在所述导管之间提供基本上气密的密封。

摘要： A joint is made between the ends of two similar lengths of flexible ducting. One end has a single ring and the other a pair of parallel rings. The single ring fits between the pair of rings. Either the single ring or the extreme ring of the pair of rings is of a larger diameter than the diameter of the ducting. The end of the ducting length with the larger ring is fitted inside the other ducting length.

摘要： A ventilation apparatus includes a plurality of tubular conduit sections, each conduit section including a first semi-tubular section and a second semi-tubular section, each semi-tubular section having a cross-sectional profile generally in the form of an open semi-circular annular element, when viewed along a longitudinal axis. Each tubular conduit includes a first engagement formation located at an end of the tubular conduit, and a second engagement formation located at an opposing end of the tubular conduit.

摘要： A joint is made between two lengths of flexible ducting by captivating a flexible resilient ring attached to one end of a length of the ducting between a pair of spaced parallel rings attached to the end of the other length of the ducting. The joint can be made by deforming the flexible ring and passing it into the end of the second length of ducting and then releasing it, when it is in position, so that due to its resilience it assumes its natural shape and is positioned between the pair of rings.
摘要翻译：通过在连接到管道的另一长度的端部的一对间隔开的平行环之间附着一个柔性弹性环，使柔性弹性环附着在管道长度的一端，从而在两段柔性管道之间形成接头。接头可以通过使柔性环变形并将其传递到第二长度的管道的端部并且当其处于适当位置时将其释放，使得由于其弹性，其可以呈现其自然形状并位于该对之间的戒指。
