  • Patent number: 5857775
    Abstract: A probe tip in combination with a seal assembly that prevents debris and other contaminants from entering the probe tip. In the preferred embodiment, the seal comprises a tube with a filter holder assembly attached at the distal end of the holder. The filter holder assembly includes an infrared filter seated inside a screw-on member that is attached to a holder member with a sealing member located directly behind the infrared filter. During manufacturing, a predetermined force is applied to the proximal end of the tube which drives the distal end of the tube and filter holder assembly against the probe tip opening, thereby forming a watertight seal thereto. In alternative embodiments, the seal assembly may be comprised of a collar and gasket combination instead of a filter holder assembly.

  • Patent number: 5852986
    Abstract: A CO.sub.2 cartridge is permanently attached to a cartridge status indicator so that a user need not perform a detailed inspection to determine if the cartridge has been used or not. If the cartridge has been used, the status indicator will so indicate upon casual visual inspection, and if the cartridge has not been used, the causal inspection will also reveal that fact. The gas is released by two different methods. The first requires only that the user pull a cord. Pulling the cord shifts a support member laterally within the inflator, and previously misaligned legs and bores enter into alignment with one another. When aligned, the legs enter into the bores under the influence of a spring positioned in the inflator and the support member is driven into puncturing relation to a membrane. If moisture is encountered, the cord need not be pulled because the moisture collapses a dissolvable element, and the pierce pin is driven into puncturing relation with the membrane under the force of the spring.

  • Patent number: 5853246
    Abstract: A wet bulb thermometer. A temperature sensor which can function in a moist environment is placed in such a location that it will be within the mist of water produced by a nozzle when pressurized water is supplied to the nozzle. Preferably, the temperature sensor is placed somewhat below the nozzle to account for the effect of gravity upon the mist of water. Also, preferably, the temperature sensor produces an electrical signal that is indicative of temperature and that can be read by a computer. Accuracy of the determination of the wet-bulb temperature of the air is assured by the redundancy of this device. Evaporation from droplets in the mist assure that the temperature of the air within the mist is at the wet-bulb temperature as, independently, does the evaporation from the film of water which forms on the surface of the temperature sensor.

  • Patent number: 5845597
    Abstract: An efficiency indicator for a separation system, such as a water filter, wherein a first volume of fluid is exposed, under a first pressure, to a separation medium and a second volume of fluid is recovered therefrom, under a second, lesser pressure. The indicator comprises a housing including an aperture and a biased piston rod in a tube driven between a first position and a second spaced-apart position by the differential between said first and second pressures when said second pressure represents an undesired loss of medium separating efficiency. The piston rod has a first reflective colored coating at one location on said rod and a second reflective colored coating at a second location. A sphere of optical transparent material is mounted so as to project through the aperture of the housing.

  • Patent number: 5839202
    Abstract: A manual three dimensional coordinate measuring machine has a probe manually movable along three orthogonal coordinate axes, X, Y and Z, and a Z axis member supporting the probe. The size and shape of a workpiece is determined by displacements along the three axes from a predetermined origin when the probe contacts the workpiece. The manual coordinate measuring machine further includes a slide ring positioned at the bottom side of the Z axis member and at least one elastic member. The slide ring is movable in an arbitrary direction relative to the Z axis and along the Z axis. The slide ring is held at a predetermined position in the plane and along the Z axis by the at least one elastic member. The at least one elastic member allows the slide ring to move in the plane or along the Z axis by elastic deformation of the at least one elastic member in response to a force which is larger than a predetermined value.

  • Patent number: 5836694
    Abstract: A system for aiming a remote IR temperature sensing device includes a laser aiming assembly and a scope assembly mounted to the IR temperature sensing device. The laser aiming assembly provides for adjusting the vertical and azimuthal positions of an alignment beam to facilitate the use of inexpensive, low-tolerance parts while providing high accuracy to improve sensitivity, accuracy, and resolution. The laser aiming assembly includes a laser aiming mirror for directing the alignment beam toward the target. The system includes a beam splitter which reflects incoming visible radiation toward the scope assembly and allows incoming IR radiation to pass through to an IR temperature sensor. The beamsplitter has an opening of sufficient size to allow the alignment beam to pass through unobstructed but not so large as to interfere with the operation of the beamsplitter.

  • Patent number: 5836192
    Abstract: For monitoring a predetermined level of a liquid in a container an ultrasonic transducer is fitted on the outer surface of the container wall at a measurement point situated at the height of the level to be monitored. The ultrasonic transducer contains a piezoelectric element which generates, when excited by an alternating voltage pulse having a given transmission frequency, an ultrasonic transmission pulse which is transferred via a diaphragm to the container wall and which converts ultrasonic vibrations transferred from the container wall to the ultrasonic transducer into electrical reception signals. So that the piezoelectric element for given dimensions can be operated in a large frequency range, and so that a good adaptation to the diaphragm is achieved, the piezoelectric element consists of a porous piezoelectric ceramic having a type 3--3 connectivity.

  • Patent number: 5836692
    Abstract: An infrared detector is positioned in a probe having nonthermocouple leads which connect to socket connectors of a standard hand-held voltmeter. The voltmeter has a clip to retain the probe. The detected voltage may indicate the difference between a target temperature surface and ambient temperature. For more accurate sensing of ambient temperature, a thermocouple may be connected in series with the thermopile with one junction at the thermopile cold junction temperature and another junction sensing ambient temperature. The ambient temperature may be that temperature surrounding the infrared detector or the temperature of the environment surrounding the meter. The infrared detector is calibrated to provide a direct reading of temperature degrees by a factor of ten on the voltage scale of the meter. To that end, multiple thermocouples may be connected in series, each with a junction responding to ambient temperature and a junction responding to thermopile cold junction temperature.

  • Patent number: 5833366
    Abstract: A method and apparatus for determining the freezing points of a metal by inducing solidification in a cooling liquid metal sample in a supercooled state and utilizing specific detected peak values or changes in slope in a temperature/time plot as the sample cools, begins solidification and recalesces. It was found that the maximum temperature reached after the second rise, if two rises occur, the maximum of a single rise, or the temperature at which the rate of temperature drop decreases, if no temperature rise occurs, provides a useful approximation of the liquidus temperature and hence the freezing point of the sample.
