  • Publication number: 20240401864
    Abstract: Described herein are methods for making clear ice. In one embodiment, a method for making clear ice includes providing a mold of any of the embodiments described herein, optionally inserting a skewer through the mold, the skewer being coupled to an item; circulating, using fluid inlet and outlet valves, a fluid in a mold cavity defined by the mold; varying overtime one or both of: a temperature of the cooling apparatus or a fluid flow rate, through the fluid inlet valve, as a percentage of max flow; and optionally retracting the skewer when the ice formation encases at least a portion of the item. The method optionally includes a period of flow reversal, such that the fluid inlet valve becomes the fluid outlet valve and the fluid outlet valve becomes the fluid inlet valve. In some embodiments, the method optionally includes releasing the ice from the mold.

  • Patent number: 12061112
    Abstract: A device, and corresponding method, for determining a presence of lead in a material composition of a pipe includes a probe, a resonant frequency measurement circuit, and a material analyzer. The probe includes an oscillator circuit and can be inserted into an interior cavity of the pipe and emit electromagnetic radiation. The frequency measurement circuit operatively communicates with the oscillator circuit and outputs resonant electromagnetic frequency measurement data indicating a resonant electromagnetic frequency of the oscillator circuit. The material analyzer receives the resonant electromagnetic frequency measurement data, and an additional measurement selected from the group consisting of (i) a measurement of power dissipation of the oscillator circuit and (ii) an interior diameter of the pipe, and outputs a positive or negative indication of whether lead is present in the material composition based on the resonant electromagnetic frequency measurement data and the additional measurement.

  • Patent number: 10883921
    Abstract: In the operation of analytical devices, and particularly laser induced breakdown spectroscopy (LIBS) devices, a number of advantages may be obtained by the use of complementary safety mechanisms, such as those that govern the operation or firing of a laser. Such complementary safety mechanisms, compared to the individual safety mechanisms acting alone, prevent operation of the laser under a greater number of unsafe circumstances (even if one or more detected conditions are safe, based on not activating the associated safety mechanism) and permits operation under a greater number of safe circumstances (even if one or more detected conditions are unsafe, based on activating the associated safety mechanism).

  • Patent number: 10689090
    Abstract: An aircraft includes a clearance between an opening and a door. The clearance communicates with a cavity and is oriented in a direction intersecting a flow direction of an air flow to the outside of the aircraft in flight. The aircraft further includes an upstream edge and an upstream outer surface situated in front of the clearance joined by a sharp edge with a bend radius of less than or equal to 1 mm, in order to limit the incidence of aerodynamic noise.
