  • Patent number: 12544464
    Abstract: Aspects disclosed herein include a device and a method for disinfecting, sterilizing, or decontaminating daily used equipment and materials within a relevant field. The device may be compact, flexible, economical, and operator friendly. The device and method may be used in hospitals, warzones, or dentist's offices to disinfect, sterilize, or decontaminate low heat resistant materials, medium heat resistant materials, and high heat resistant materials. By using a compressed gas to deliver heat, humidity, and concentrations of H2O2, and using a plurality of pre-determined openings within a plurality of communicatively connected plenums of the device, there is no need for moving parts or circulation devices.

  • Publication number: 20260000798
    Abstract: A method for disinfection, sterilization, or decontamination of an object placed inside the inner chamber of a batch oven. A compressed gas is passed through a water column, thus humidifying the compressed gas to a dew point of up to 120° F. A pre-heating device heats the compressed gas up to a temperature of 700° F. and the gas is then circulated, in one direction, from the pre-heating device to a plurality of plenums of the batch oven. The plurality of plenums are communicatively connected to the inner chamber via a pre-determined number of a pre-determined size and the compressed gas is introduced into the inner chamber via the plurality of plenum openings. The object is then maintained in the inner chamber for a pre-determined period of time.

  • Patent number: 10583487
    Abstract: A method of producing a finished essentially 100% dense homogenous alloyed metallic product. First, a metal powder is provided comprised of particles with each particle having a predetermined alloy content. Next, the metal powder is blended with a mixture of a lubricant and a binder to form a composite powder. That composite powder is then compacted in a compacting die at room temperature to form a green part. The lubricant and binder are then removed by heating the green part to at least a first temperature profile in a confined atmosphere with a predetermined dew point profile. Next, the remaining green part is heated to a second temperature higher than the first temperature and with predetermined dew point and H2/H2O ratio in a furnace atmosphere to remove surface oxides from the part. Finally, the part is densified into a finished or near net shape homogenous alloyed product.
