摘要： A pipe plug includes two or more pivotally connected plugging heads that work in combination to double block and bleed a pipe. At least one of the plugging heads has an expandable sealing element that is in communication with an inflation source. The sealing element may be an inflatable sealing element or a compression packer sealing element. A passageway-sections of which may pass through the pivotal connection and into the plugging head-carries the inflation medium from the source to the sealing element. A bleed port passageway is also provided that passes through the plugging head. The leading plugging head may include a cleaning element for sweeping away debris ahead of the plug. The plugging heads may also include a skid plate that slideably engages the interior surface of the pipe to properly orient the plugging heads within the pipe.

摘要： A seamless inflatable bag (13) is made with two layers, namely an outer layer (17) made of a woven material such as from p-aramid and an inner gas proof layer (19) . The outer edges of the layers are brought together around a tube (21) and secured in place by a sleeve (29) that is crimped in place such that the outer edges are interposed between the sleeve and the tube. A second sleeve (22) can be crimped on to the first sleeve for further strength. This arrangement provides an airtight seal, wherein fluids such as gas or liquid can be provided to the interior of the bag to inflate the bag upon command. The bag can be used to lift objects (31) such as in place of a vehicle jack or can be used to plug a pipe (123). To inflate the bag, an air compressor (33) provides compressed air to the interior of the bag. To deflate the bag, the compressed air is bled away from the bag.
摘要翻译：无缝充气袋（13）由两层制成，即由诸如对位芳族聚酰胺之类的编织材料制成的外层（17）和内部防气层（19）。这些层的外边缘围绕管（21）汇集在一起，并通过套筒（29）固定就位，该套筒（29）压接在适当位置，使得外边缘介于套筒和管之间。为了进一步的强度，第二套筒（22）可以压接到第一套筒上。这种布置提供了气密密封，其中可以向袋的内部提供诸如气体或液体的流体，以便在命令时使袋充气。袋子可用于提升物体（31），例如代替车辆千斤顶或可用于堵塞管道（123）。为了给袋子充气，空气压缩机（33）向袋子内部提供压缩空气。为了给袋子放气，压缩空气从袋子里冒出来。

摘要： A system for sealing a building air duct in response to a chemical or biological attack to prevent the building HVAC system from delivering the chemical or biological agent throughout the building. The system can include an inflatable bladder for disposition within an air duct, a source of gas for expanding the bladder, an initiator for initiating the gas expansion, and a detector for detecting the agent. One bladder is formed of a resilient material suitable for extending into duct corners. Another bladder is larger than the duct to be sealed and is formed of a non-resilient material capable of inflating and bunching into duct corners. One source of gas is a gas canister while another source of gas is a chemical composition capable of reacting and forming the gas. One bladder includes a foaming agent which can expand and solidify within the bladder. One initiator utilizes an electronic signal to initiate the gas expansion. Another initiator includes use of an RF signal to initiate the gas expansion. One agent detector samples duct air while another detector includes a horizon detector for detecting agents in the air outside the building.

摘要： Pipeline shut-off devices of a transport vehicle are fitted at a predetermined insertion point in a pipeline by off-shore technology and secured by means of special fastening and sealing devices. In order to remove the shut-off device, it must be possible to dismount the fastening and sealing devices. To this end, a device has a piston (5a) which moves in a cylinder (4a), the piston rod having a coupling head (3a) for coupling a transport vehicle, and the cylinder chamber on the piston rod side is connected via a pressure line (9a) to a resetting chamber (13a) of the hydraulic actuating device for the sealing device in such a way that the latter is retracted when a tractional force is applied to the coupling head (3a).

摘要： A technique is provided for isolating a pipe during maintenance or servicing of the pipe. The technique may utilize a control bar head having a coupling feature for coupling with a control bar. The control bar head also has a bleed passage extending therethrough to the coupling feature and thus to the control bar when engaged with the control bar. Additionally, the system may comprise a first sealing head slidably engaged with the control bar head. The first sealing head may comprise a first seal element and a first sealing head bleed passage extending therethrough to the control bar head. The system also may comprise a second sealing head slidably engaged with the first sealing head and having a second seal element. The first sealing head bleed passage may be arranged to extend to a region between the first sealing head and the second sealing head to facilitate bleeding of this region.

摘要： A removable seal for collecting debris in a drainage pipe section of a shower base during construction, the seal comprising a stem member having a proximal end, an opposed distal end, and an airflow passageway extending from the proximal end to the distal end, the stem member comprising a one-way valve, located at or near the proximal end, configured for allowing air to flow only into the passageway; and an inflatable member sealingly mounted to the stem at the distal end so as to be in fluid communication with the passageway, the inflatable member being configurable between a deflated state for insertion into, and subsequent removal from, the drainage pipe section, and an inflated state in which the inflatable member substantially seals against walls of the drainage pipe section for collecting fallen debris and thereby preventing debris from falling further into the pipe.
