  • Patent number: 11770878
    Abstract: The invention relates to an electric machine (fixed, mobile or portable) suitable to the physical, dynamic, continuous conditioning of materials having the ability to absorb electromagnetic radiation, which have the need to be treated through the irradiation of UV or IR, even without entering into contact with the machine and this also through the vacuum. The invention mainly uses the Lambert and Stefan-Boltzmann postulates, or rather the physical assumptions of the transmission of energy by radiation and in particular the concentration and the emission proximity of energy between transmitter and receiver (which varies with the square of the distance) and the emission intensity (which varies with the fourth power of the temperature). The extremely small distances between transmitter and receiver of electromagnetic energy and the cylindrical shape and concentric electromagnetic emission source (reflected from the outside towards the centre) are the main essence and novelty of the invention.

  • Patent number: 11643623
    Abstract: Alcoholic spirits may be artificially aged under highly pressurized carbon dioxide. The carbon dioxide may form carbonic acid, which may cause various esters to form in the presence of wood as well as to mellow the flavor when no wood is present. Wood may be pretreated with ozone, which may extract lignin which may further convert to vanillin during pressurized CO2 treatment, giving a vanilla note. After processing with pressurized CO2, a post-treatment of ozone may be given to the spirit, which may cause a mild oxidation and further mellowing of the spirit.

  • Patent number: 11639225
    Abstract: A solid-state radio frequency (SSRF) water heating apparatus is disclosed. In embodiments, the SSRF water heater includes a water tank, SSRF generator array and RF sensors enclosed within an RF-shielded cage. The SSRF array synthesizes RF signals in the microwave range and transmits the RF energy through the water tank, exciting and heating the water molecules without direct contact. The RF sensors at the opposite end of the tank sense residual RF energy not absorbed by the water. Control processors regulate the generation and transmission of the RF energy based on the sensed residual energy. The heated water and/or generated steam is piped to hot water dispensers, beverage makers, or steam ovens.

  • Patent number: 11638331
    Abstract: The present technology is directed to multi-frequency controllers for inductive heating and associated systems and methods. The systems can be configured to precisely heat a module via a coil to a target temperature using oscillating, pulsed electrical signals associated with unique frequencies and/or capacitance values. Each unique frequency can correspond to heating the module to a particular depth, relative to an outer surface of the module. A first pulsed electrical signal having a first frequency can heat the module to a first depth, and a second pulsed electrical signal having a second frequency can heat the module to a second depth different than the first depth. The system can include a thermal sensor for measuring a temperature associated with at least one of the module or a fluid associated with the module. Based on the temperature, the system can adjust signal delivery parameters of the first and/or second electrical signals.
