摘要:
A pool-water heater manifold in fluid communication with other components of a pool-water circulation system, the manifold comprising an inlet for receiving pool water from another component of the pool-water circulation system; an outlet for transferring pool water to another component of the pool-water circulation system; a low-restriction chamber configured to allow water to flow from the inlet to the outlet; a plurality of openings for directing water to a heating device; a barrier positioned at least partially within the chamber; and means for repositioning the barrier from a first position, in which the barrier obstructs passage through the chamber of substantially all of the water received by the inlet, to a second position, in which the barrier allows passage through the chamber of substantially all of the water received by the inlet.. The pool- water heater manifold includes a low-restriction chamber having low impedance to water flow therethrough and repositionable gates or other valves within the chambers. The valves may direct water as a function of whether an associated heating device is active. At least some gates may incorporate poppet valves or other high-flow bypasses. Disclosed is furthrmore, a method of operating a pool-water heating system by causing pool water to enter a manifold of a heating device; and positioning a barrier within the manifold so as to allow pool water to flow from an inlet of the manifold to an outlet of the manifold without significant restriction if the heating device is inactive or from the inlet of the manifold to the heating device when the heating device is active.
摘要:
The invention relates to a three-dimensional structural framework (10) comprising a plurality of inflatable rings (100), having a T-shaped cross-section along a plane passing through an axis of revolution of the inflatable ring in an inflated state, and a plurality of means (150) for stabilizing the shape of the structural framework in space, two inflatable rings (100) being connected by at least one shape-stabilizing means (150). The structural framework is advantageously intended for producing stratospheric balloons.

L'invention est relative à un dispositif de mesure (100) de mesure de l'état d'une voie de circulation d'un véhicule guidé, ladite voie de circulation comportant un rail de guidage (1), d'axe longitudinal X, destiné à accueillir un organe de guidage dudit véhicule guidé, ledit rail de guidage comportant une tête dite champignon. Le dispositif de mesure comporte un chariot de guidage (10), destiné à être disposé le long de l'axe longitudinal X du rail de guidage (1), deux organes palpeurs, solidaires du chariot de guidage (10), destinés à être positionnés de part et d'autre du rail de guidage lorsque le dispositif de mesure est en position sur la voie de circulation, un moyen de rappel d'un organe palpeur vers l'autre organe palpeur, un organe de mesure de l'écartement entre les deux organes palpeurs.
摘要:
The invention relates to an anaerobic propulsion device of hybrid type, said propulsion device comprising a combustion chamber (21) into which an oxidant is injected to come into contact with a fuel, said chamber (21) comprising an orifice (notably a nozzle) for the ejection of the combustion gases, characterized in that the fuel takes the form of solids divided into granules (typically grains, powder or beads). The propulsion device comprises a segregation device (22) arranged between a reservoir (27) for granules (23) of solid fuel, and a combustion chamber (21), the segregation device (22) being designed to prevent granules (23) of fuel in solid form from passing between the reservoir (27) and the combustion chamber (21), but comprising orifices allowing the passage of fuel, once this fuel has become pasty, liquid or vaporized.
摘要:
Automatic pool cleaners (APCs) and components thereof are detailed. The APCs may include tracks for movement, with the tracks having teethed internal surfaces. The APCs additionally may supply shift mechanisms for purposes of changing direction of their movement and incorporate bladed scrubbers and easily-opening bodies.

The invention relates to a sampling tool (1'), characterised in that same includes: a guiding body (1) provided with a through bore (10); a part-carrying punch (2) mounted slidingly adjustable in the bore (10), comprising a lower edge (20), forming a cutting edge; a part-carrying die (3) separated from the guiding body (1) by an opening (4), being provided with a through bore (30) which the lower end (20) of the punch (2) enters when cutting of the sample to be collected, and being provided with a cutting upper edge; a means for actuating the punch (2) between an initial position, in which said punch is retracted into the body (1), a stationary intermediate position, in which the punch is positioned by the edge (20) thereof in the bore (30), and a final position in which the punch passes through the die (3) from one side to the other, the lower edge thereof being outside of the bore (30). The path of the punch (2) is tangential to the surface (310) of the opening (4) and the bore (30) is tangential to a geometric plane containing said surface (310) in order to make a cut with an open contour in the plant from which the sample is collected.
