摘要： A highly extendable and retractable dual elastic hose comprises a tubular inner fluid conduit made of an elastomeric material and an elastic tubular outer sleeve of interwoven webbing made out of braided strands of textile yarns wherein embedded a plurality of evenly distributed highly elastic rubber strings extending horizontally along its longitudinal length. The inner tube is secured to the tubular outer sleeve only at an inlet coupler and an outlet coupler. Both the inner tube member and the outer tube sleeve can automatically expand longitudinally up to five times its unexpanded or contracted length resulting from pressurized fluid within the hose. To provide a linearly extendable and retractable dual elastic hose constructed with elastic materials both in the inner tube and the outer sleeve, it shows advantages of an improvement in expandable ratio of the outer sleeve and a reduction of strain forces required for the inner elastic tube to elongate the outer sleeve. A prolonged service life of the dual elastic hose is expected due to an effective reduction of frictional contacts and frictional resistance between the internal wall of the outer sleeve and the outer wall of the inner tube from less relative movements a lubricant layer between the two walls.

摘要： The invention involves a modular elevated hose hanger system. The system includes a vertical support member suitable for insertion into a ground surface for elevating the hose hanger and preventing unwanted rotation of the hose hanger about the vertical axis of the vertical support member. The hose hanger is constructed of a cylindrical segment having features for interlocking with the vertical support member. A modular face plate cooperates with the cylindrical segment to provide structural support to the cylindrical segment while being easily removable and replaceable.

摘要： A hose which automatically expands longitudinally and automatically expands laterally upon the application of a pressurized liquid is disclosed. The hose can automatically expand longitudinally up to six times its unexpanded or contracted length. Upon release of the pressurized liquid within the hose, the hose will automatically contract to a contracted condition. The hose includes an inner tube made from an elastic material and an outer tube made from a non-elastic material. The inner tube is positioned concentrically within the outer tube in both a contracted condition and an expanded condition. The outer tube is secured to the inner tube only at a first end of the inner and outer tubes and at a second end of the inner and outer tubes. The outer tube moves laterally and longitudinally with respect to the inner tube when the tubes are transitioning between a contracted condition and an expanded condition.

摘要： A conduit for use in a pressure support system for communicating a flow of pressurized gas to the airway of a patient includes a first strip of a first material disposed helically about a central longitudinal axis such that subsequent helical convolutions of the first strip are disposed adjacent each other, and a second strip of a second material disposed helically about the central longitudinal axis along the first strip. The second strip is coupled between the subsequent helical convolutions of the first strip so as to form a hollow conduit. The first material is structured to prevent the passage of fluids therethrough. The second material is structured to allow passage of a liquid therethrough while inhibiting passage of gases therethrough.

摘要： A method and apparatus are disclosed for providing erosion protection to self-interlocking windings of a carcass layer of a flexible pipe. The method includes the steps of, via a wound sacrificial insert located over at least a portion of an inner facing surface of self-interlocking windings of a carcass layer, shielding at least a flow facing edge region of each self-interlocking winding from abrasive elements carried by a bore fluid flowing along a bore of the flexible pipe from an upstream to a downstream location.

摘要： A hose arrangement includes an outer tube of flexible material and an inner tube of an elastic material for carrying fluid. Due to an action of the elastic inner tube, the hose has a shorter length in a contracted state in the absence of fluid pressure in the interior of the inner elastic tube and a longer length in an expanded state when the fluid pressure is applied to the interior of the elastic inner tube. The tube has an undulating state in the contracted state and controls and contains expansion of the inner tube when the hose is in the expanded state. At least one sleeve portion is provided between the elastic inner tube and the outer tube along a part of the elastic inner tube where undulation of the outer tube occurs in the contracted state for protecting the elastic inner tube from abrasion undulations of the outer tube.

摘要： Pliable-wall air ducts with internal expanding structures are disclosed. An example air duct system includes an air duct including a pliable sidewall. The example air duct system further includes a shaft including a first end and a second end. The shaft extends in a longitudinal direction along a length of the air duct with the first end coupled to a first point of the air duct and the second end coupled to a second point of the air duct. The first point is downstream of the second point. The pliable sidewall is to be held in tension in the longitudinal direction between the first and second points in response to compression in the shaft between the first and second ends.

摘要： A water pipe includes a pipe body (1), a woven layer (2) sleeved around the pipe body (1), a first joint assembly (3) arranged at one end of the pipe body (1) and secured to the pipe body (1), and a second joint assembly (4) arranged at another end of the pipe body (1) and secured to the pipe body (1); the woven layer (2) includes bamboo charcoal fibers and polypropylene filaments. The woven layer (2) is sleeved around the pipe body (1) and is not connected with the pipe body (1), and the woven layer (2) includes bamboo charcoal fibers and polypropylene filaments. Bamboo charcoal fibers have the functions of resisting bacteria and removing peculiar smell and can effectively prevent the generation of bacteria on the water pipe and the emission of peculiar smell when the water pipe is used in humid outdoor environments.
