摘要： A collapsible article comprising a plurality of foldably interconnected foldable sections/modules. The foldable sections can be part of cylindrical or conical surfaces. They can also be in the form of closing sections. When the foldable sections are part of tubular surfaces, either cylindrical or conical, they consist of four polygonal surface segments. The polygonal segments are curved/round in unfolded state and have a flat or approximately flat shape in partly folded and folded states. The folding process usually involves an abrupt transition between the unfolded and folded positions which makes the unfolded article almost as stable as non-foldable equivalents. The folding process usually requires application of force on the edges that form valley creases during folding.

摘要： A containment sleeve for use with a pressurized piping system including a pliable fabric sheet having first and second opposing longitudinal edges, first and second opposing transverse edges, and first and second opposing major surfaces respectively defining an interior and exterior surfaces. At least one pleat extends between the first and second transverse edges, the pleat being in a normally closed position to define the interior surface with a first surface area. The sheet of pliable fabric to secure about a portion of a pressurized piping system with the interior major surface facing the pipe so as to form a sleeve having an initial interior volume there about. In response to a rupture of the pressurized piping system within the interior volume, the pleat to expand to an open position to expand the interior surface to a second surface area to increase the interior volume from the initial volume.

摘要： The present invention refers to loading crane comprising:

an articulated arm, comprising at least one first and one second bodies successively connected in order to form an open kinematic chain, wherein the second body is translatingly and/or rotatably movable with respect to the first body;
a hydraulic circuit adapted to convey a working fluid for actuating the articulated arm.

Said hydraulic circuit comprises a segment associated to one of the first and second bodies comprising:

at least one sliding rigid tube slidingly translatingly connected to the body to which the segment of the hydraulic circuit is associated;
at least one stationary tube integrally connected to the body to which the segment of the hydraulic circuit is associated;
a flexible tube fluidically interconnecting the sliding rigid tube and the stationary tube.

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.
