  • Patent number: 10663388
    Abstract: A system and method for accurately and efficiently testing a HEPA filter in a sterile environment, such as a clean room, by creating a closed-loop system. The system includes a multi-port interface including at least a challenge port and a verification port, each port being in communication with an area upstream from the HEPA filter. Through the challenge port, test substances are introduced to a supply air duct that is in communication with a HEPA filter. Through the verification port, a concentration of the test substances can be measured for comparison with a concentration that passed through the HEPA filter, i.e. downstream from the HEPA filter. As such, test substances can be dispersed throughout the air conditioning system before interacting with the HEPA filter, and accurately measured. The closed loop between the ports provides an accurate measurement of the concentration of test substances to test the HEPA filter.

  • Patent number: 10345215
    Abstract: A filter has a rectilinear configuration with top and bottom surfaces, front and rear surfaces, and side surfaces. A ceiling has a coupling plate with a test port and a sensor port. Test equipment located below the ceiling is adapted to generate a flow of input aerosol. A coupling line is positioned between the test equipment and the test port. Sensor equipment is positioned below the ceiling and is adapted to sense a flow of output aerosol. An output line is positioned between the sensor equipment and the sensor port. First and second intermediate lines are operatively coupled between the test port and the filter and between the filter and the sensor port. An air conditioner line is operatively coupled to the top surface of the filter.

  • Patent number: 5756970
    Abstract: A method for converting standard conventional oven cook times and temperatures to convection oven cook times and temperatures to operate a thermal convection oven is provided. The method has the steps of providing a thermal convection oven having an oven cavity, a heating element, a control panel for inputting cooking parameters, a converter for converting a standard conventional oven cook time and temperature to a convection oven cook time and temperature, the converter being connected to the input control panel, and having controls connected to the converter and also connected to the heating element for operating the thermal convection oven.

  • Patent number: 5438180
    Abstract: An electronic control for a cooking oven includes an input selection panel for receiving user input selections and control logic responsive to the input, selection panel for establishing a time and temperature profile of the oven cavity and for controlling heating devices according to the time and temperature heating profile entered by the user. The input selection panel includes heating function selection devices for receiving user selection of a heating function from among a plurality of heating functions and timing function selection devices for receiving user selection of at least one timing function from among a plurality of timing functions. The timing functions are independent of the heating functions so that a user may select any combination of timing functions with any selected heating function. The input selection panel includes labeled selection devices and labeled parameter display devices that define a grammatical sentence. The sentence emulates standard instructions in a cooking recipe.
