  • Patent number: 5678925
    Abstract: A hot beverage mug automatically senses the temperature of its liquid contents and generates an accurate aural and/or visual indication of the temperature sensed. The temperature is sensed by a thermistor in a resistive capacitive (R/C) circuit which operates to yield a signal of variable frequency corresponding to the temperature sensed. An integrated circuit (IC) logic controller treats this electrical signal as an input which triggers a further electrical signal from the IC controller to an aural or visual display generating device such as an annunciator, a light emitting diode (LED), liquid crystal display (LCD) or a simulated voice expressing the temperature sensed. The power for the R/C circuit, the IC and the aural/visual indicator(s) is supplied from a battery and controllable by a switch activated either manually or automatically upon sensing the pressure of the liquid contents or by physical contact with the mug handle.

    Abstract: The present invention is related to a device and method for determining the flash point of a liquid or solid material to be tested by measuring the pressure obtained in the measuring chamber after an ignition. According to the invention, a liquid or solid is placed into a measuring vessel and the measuring vessel is heated. The measuring vessel is tightly closed with a cover. At a given temperature the generated vapor-air-mixture is ignited and the pressure increase occurring due to the temperature increase is taken as a measure for the size of the flame for determining the flash point. The pressure increase is preferably measured with a piezoresistive pressure transducer. The temperature of the heated cover is measured with the temperature sensor and the sample temperature with the temperature sensor.

  • Patent number: 5138891
    Abstract: A system for a gauge well in a liquid storage tank with a floating roof including a floatable container located inside the gauge well and having a flexible laterally or radially serrated flange extending outward from the float and in contact with the inside of the well pipe to prevent vapor from the liquid stock from rising in the pipe. There may be a pair of such flexible flanges vertically spaced apart with the lower seal being just above the level of the liquid stock in the well pipe. A tape is attached at its lower end to a weight in the well pipe below the float and its upper end is connected to a winch outwardly of the upper end of the well pipe. A vertical passageway through the float is provided for the tape to pass freely therethrough and the float is freely slidable on the tape. The container includes a closed opening which is selectively opened to fill with the liquid stock at any selected level in the tank.

  • Patent number: 4883365
    Abstract: The device of the invention consists of a temperature sensitive device embedded in a matrix which provides a useful heat flow pattern. Apparently the device exploits the difference in the thermal conductivities of air versus other media, such as water or slurries, to function. Plastics are the preferred matrix material for most applications. The insulating and non-wettability properties of plastics may contribute to the observed useful properties as well. The chemical resistance of certain plastics can provide additional useful variations. The invention is especially useful as an aid to fishing. The device readily and simply identifies which waters have the best chance of containing fish. Other examples are municipal drinking water tanks, liquid cargo tanks, oil and water wells, etc.

  • Patent number: 4591566
    Abstract: A system is disclosed for monitoring sterilization of biologically contaminated material from hospitals and the like. An autoclave sterilization unit heats biologically contaminated materials with steam for a time sufficient to kill the contaminants therein. A biological indicator probe provides for inserting a test vial into the central portion of the materials being treated. After sterilization, the probe is removed and the test vial is cultured to determine whether the spores of the Bacillus stearothermophilus, or the like (e.g. Bacillus sp.) present are still viable. If the test vial has been completely inactivated, it is an indication that decontamination of the other materials in the autoclave is complete. The test probe comprises a rod of heat resistant material having an end chamber closable by a rotatable sleeve. In a position aligning window openings in the chamber and in the sleeve, the test vial may be inserted. Rotation of the sleeve locks the test vial in place.
