  • Patent number: 4633803
    Abstract: An instrument gauge is described of the pointer output type, especially a tachometer, that includes a display cover limiting observation of the pointer by a first window cut into the cover in the shape of a graphical representation of a proportional relationship between engine performance and revolutions per minute or vehicle speed. The window is oriented such that the pointer position indicates RPM or speed on a cover scale. Engine performance is indicated by the relative position of the pointer with respect to the curved shape of the window established by the proportional relationship. The cover includes a second window of such size and orientation that it permits observation of the pointer only when a critical RPM or speed is reached. A flag fixed to the pointer appears in the second window only at the critical value.

  • Patent number: 4631956
    Abstract: An Air Deployed Oceanographic Mooring when assembled for deployment has a multitude of components suitable for separation by explosive bolts upon deployment of the system. A parachute system is connected to a surface buoy. The components that separate from each other upon deployment comprise a parachute system, a surface float, a subsurface buoy, an anchor shell and a bottom finder. All components except for the parachute system have interconnecting flexible lines upon deployment. A novel locking mechanism for limiting the paying out of the line between the anchor shell and subsurface buoy is triggered by the slackening of the line between the bottom finder and anchor shell when the bottom finder hits the bottom of the ocean.

  • Patent number: 4630938
    Abstract: A method and apparatus for determination the thermal conduction coefficient and the heat capacity of materials. The method comprises the measurements of heat flux across the sample and the momentary temperature difference between both surfaces of the sample perpendicular to the direction of heat flux during continuous change of the temperature of one of sample surfaces. The values of thermal conduction coefficient, heat capacity and thermal diffusivity are determined on the basis of an equation which defines their dependence on measured heat flux across the sample, temperature difference between the sample surfaces and the rate of the change of the temperature of one sample surface. The apparatus for measuring thermal conductivity and heat capacity contains a heater equipped with a temperature sensor of a thickness less than 1 mm, placed between two samples, one of them being the sample of material tested of a thickness less than 10 mm.

  • Patent number: 4629336
    Abstract: An electronic clinical thermometer capable of executing plural temperature prediction functions in which elapsed measurement time is a variable, each function prescribing a temperature change up to a final, stable temperature. One of the temperature prediction functions is set, and actual body temperature is sensed at a specific point in time. Then, based on the sensed temperature and selected function, a final temperature is obtained at least twice in accordance with a time series and the temperatures are compared to obtain a difference between them. When the difference falls outside prescribed limits, a new temperature prediction function is selected, a final temperature is obtained based thereon, and the foregoing process is repeated until a difference is found which lies within the prescribed limits. The final temperature obtained at such time is delivered as an output indicative of measured temperature.

  • Patent number: 4629333
    Abstract: A radiation source directs light at a mirror which reflects to a first photosensor. As a dew point is reached, scattered light is reflected to a second photosensor to indicate dew point. Rather than periodically interrupting operation to test reflectivity of the mirror or to perform a heating cycle, operation is monitored continuously. The common mode output of both the first and second photosensors is monitored. When below a threshold level, the output indicates the need for cleaning the mirror. It may also be used in a closed loop to increase light source intensity as mirror reflectivity decreases.

  • Patent number: 4627740
    Abstract: A self-calibrating temperature sensing probe having a temperature sensor positioned adjacent to a vial of a predetermined substance in an isothermal environment created by a housing and insulation. A heating element is positioned about the vial to effect vial heating. The substance is preselected for its melting point temperature, which is in excess of the ambient temperature of the environment surrounding the housing. During recalibration the substance is heated above its melting point and allowed to cool. During cooling the temperature of the substance is recorded and the liquid-to-solid phase change determined. Recalibration is affected using the phase change temperature of the substance as a calibration point.

  • Patent number: 4627378
    Abstract: A wedge shaped hollow float is mounted by one end to a channel bolted to the inside of the sloping roof of a grain bin approximately two feet from the top thereof. A curved rod is pivotally secured by the inner end thereof to the other end of the float and extends through the channel and through the roof and has an indicating disc on the outer end thereof. As the bin fills, the angle of repose of the grain engages the other end of the wedge shaped float and gradually lifts it as the bin continues to fill. When the indicator is fully extended, a rod and disc indicates to the operator that the flow of grain to the auger hopper should be shut off and the two foot space at the top of the bin is sufficient to hold the grain left in the auger and in the hopper thus avoiding any spillage.
