  • Patent number: 5880438
    Abstract: A steam sterilization apparatus (10) includes an electronic control system having a main control circuit (C) including a central processing unit (68), an input device (36), and output devices (24,28) provided on a single circuit board (22) which is attached to a front bezel (16) of the sterilizer (10). The sterilizer (10) includes a flash steam generator (56). The main control circuit (C) implements an over-temperature feedback circuit (160) that disconnects the heating elements (162) in the steam generator (56) from electrical power when an over-temperature condition is detected. Isolated feedback is provided to the central processing unit (68) confirming the heating element disconnection operation. The control system includes error switches (82, 86, 88) that detect various error conditions. Upon an error condition being detected, the steam supply to the steam sterilization chamber (12) and/or to the pressurized steam seal (42) of the apparatus (10) is halted.

  • Patent number: 5805765
    Abstract: Steam generating apparatus in the form of a thin, compact generally self-contained wall-mountable fixture. The fixture includes an upright front face section of porcelain or the like for being mounted in the wall of a shower or other enclosed steam room. The fixture further includes a frame that is fixed to the rear of the face section and supports a closed steam tank or boiler. A steam line delivers live steam from the boiler into the steam room. An steam head delivers the steam safely and with minimum noise. The fixture may also include a mirror and be mounted so that the mirror is face height of a standing user. The mirror is positioned adjacent to the boiler so that heat radiated from the boiler warms the mirror and inhibits it becoming fogged over by the steam in the room. The fixture also includes an electrical control system that is operable by the user from inside the steam room.

  • Patent number: 5659656
    Abstract: A method is disclosed for mechanically and electrically bonding metallic materials and semiconductor materials. The method according to the invention may be used, for example, in forming a semiconductor electrical heater, particularly for use in electrical smoking articles. A metallic element, such as a copper alloy power supply tab, is laser welded to a semiconductor element, such as a doped silicon resistive heater element. A laser beam is directed through a hole in the copper alloy tab to melt some silicon material, which flows into the hole in the copper tab, reacts and intermixes with the copper and solidifies to form a slug containing copper silicide. A protective material such as nickel may be applied to protect the copper silicide from oxidation if desired. An ohmic, low resistance contact and high strength bond is provided between the parts.

  • Patent number: 5343747
    Abstract: A humidity measurement process and humidity measurement scale are derived from the physics of relative humidity. Absolute moisture content is determined independent of any measurement or knowledge of the source temperature. The humidity measurement is equivalent to the volumetric fraction of water vapor in the measured gas mixture, expressed as a percentage in a fixed range from 0 to 100%. The operating principles of the measurement process and measurement scale are described for use with an instrument suitable for humidity measurements in process ovens, product dryers, exhaust stacks, and similar environments operating at temperatures to 1250.degree. F. and near atmospheric pressure. The instrument is a point-source sampling system. A continuous sample of process air is induced to flow through the instrument for humidity measurement.

    Abstract: A humidifier for use with a forced air heating system. The humidifier comprises a water reservoir in the form of a sealed container having a water inlet connection and suitable control means for maintaining the level of the water at a predetermined depth within the reservoir. An electric immersion type heater is also provided within the sealed container at a level which is normally below the water level and, when energized, heats the water to produce steam. The reservoir can be mounted completely external to a duct of the forced air heating system, but an inverted U-shaped tube having preparations along the base thereof is disposed within the duct and has its parallel legs passing through the duct and reservoir so as to communicate with the portion of the reservoir above the level of the water therein. As such, the steam passes through the U-shaped tube and out its perforations to thereby add moisture to the air passing through the duct.
