  • Publication number: 20230392861
    Abstract: The present invention corresponds to a gas cooling and condensing system using fluid energy and comprising a gas feed line, a first vortex tube connected to the gas feed line, a second vortex tube connected to the first vortex tube and a first heat exchanger connected to the second vortex tube and to the gas feed line. Said gas cooling and condensing system is a modular system, which may be replicated and connected in series or in parallel to another modular system to obtain a cooler or higher mass flow gas than that obtained with a single modular system. Moreover, the system of the present invention is optionally connected to thermal recovery, pressure recovery, recirculation or venting elements for the utilization of the waste gas streams. Furthermore, the system of the present invention does not require additional energy to that obtained from the pressure of the feed line for obtaining liquefied gas.

  • Patent number: 11613344
    Abstract: A wing, a method of controlling lift on a wing, and a system to produce lift on a wing are provided. The wing may include a fore-element, an aft-element, a pivotable linkage that operatively connects the aft-element leading edge to the fore-element trailing edge in a span-wise direction, and an actuator. The actuator may deflect the aft-element through a predetermined deflection angle about the pivotable linkage relative to the fore-element within less than or equal to two convective periods. The method may include deflecting a span-wise flap through the deflection angle in less than or equal to two convective periods to produce high lift. The system may include a sensor to detect an input and a controller to deflect the span-wise flap of the wing by the deflection angle in not more than two convective periods based on the received input signal.

  • Patent number: 11173471
    Abstract: The production of an oxygen-absorbent composition is provided, having: (a) a porous silica encapsulation matrix; and (b) a composition containing an oxygen-absorbent compound selected from fatty acids, unsaturated esters or compounds containing same, and, optionally, a catalyst based on an inorganic salt of a transition metal, wherein the composition (b) is encapsulated in the porous silica matrix (a). The composition can form part of the structure of the packaging for oxidation sensitive products or be placed in the surrounding atmosphere to reduce the concentration of oxygen. A method for encapsulating the active compound or the active compound together with a catalyst, and subsequently incorporating same into polymer matrices is also provided.
