  • Patent number: 11744573
    Abstract: A system is transluminally advanced into the heart of a subject. A first portion of the system is positioned through a native valve of the heart, the system including wires disposed at the first portion. The first portion is stabilized at the native valve by positioning a distal portion of the system within a blood vessel of the subject. While the distal portion of the system remains within the blood vessel, the wires are induced to bow laterally such that the wires press against the native valve. While the wires remain pressed against the native valve, the shape of the wires is radiographically imaged. An anchor is transluminally anchored to tissue of the native valve, facilitated by the imaging. Other embodiments are also described.

  • Publication number: 20230227935
    Abstract: THIS invention relates to a method of recovering metal values such as gold, copper, nickel, zinc and uranium from ores containing said metal values. The method includes the steps of crushing an ore (10) to provide a sand containing metal values with a P80 of less than 5 mm but greater than 1 mm; classifying the sand (12) to remove a finer fraction to provide classified sand with a P10 of greater than 0.15 mm, and a P90/P10 ratio of less than 25 and greater than 3, forming a heap (18) from the classified sand, and distributing leachant and air through the heap to leach the values from the sand in a pregnant leachate, from which the leached values may be recovered. The invention also relates to a heap formed from ore processed by this method.

  • Publication number: 20230202660
    Abstract: An ice protection system for an aircraft includes one or more heaters configured to be coupled to a surface of a wing of the aircraft. The ice protection system also includes a controller configured to, in response to a first determination indicating presence of an icing condition, determine a setpoint temperature for a first location of an outer surface of the wing configured to be heated by a heater of the one or more heaters. The controller is also configured to control power provided to the heater based on the setpoint temperature. The setpoint temperature for the first location is determined to cause a second location of the outer surface of the wing, which is heated by the heater and is located at a particular distance from the first location, to remain above a threshold temperature based on a projected temperature profile of the outer surface heated by the heater.

  • Patent number: 11679907
    Abstract: In the alcohol market or in the liquor industries, it is common to find that the packaging activity is carried out in glass bottles and on some occasions in PET (POLYETHYLENE TEREPHALATE) and PP (POLYPROPYLENE) type containers. In the case of these latter packages, there are problems of conservation of quality, aroma and flavor, since they give off particles because they are not completely resistant to alcohol. Now, glass bottles are the most used since thanks to their 10 barrier property they preserve the flavor and quality of these kinds of drinks for longer, maintaining the level of alcohol, aroma and flavor from bottling but having serious transport and packaging problems.
