  • Patent number: 4114448
    Abstract: The disclosed apparatus is presented, for ease of comprehension, in terms of apparatus for servicing refrigeration systems, the disclosed apparatus using readily obtainable temperatures, rather than using the prior-art method of breaking into a refrigeration line for the purpose of measuring pressures.An added feature is the ability of the apparatus to provide either absolute temperature read-outs for the temperature at the desired locations, or a differential temperature read-out for the temperatures between two desired locations. Moreover, the disclosed apparatus permits vacuum read-outs and pressure read-outs, again without the necessity of breaking into the refrigeration lines.Since various refrigeration systems use different refrigerants, the disclosed apparatus also has the ability to convert the temperature read-outs to pressure read-outs that are associated with specific refrigerants.

  • Patent number: 4112761
    Abstract: This invention relates to an apparatus for measuring and recording the changes in magnitude of a variable. The apparatus includes a recording stylus or pencil and a means for carrying a recording medium such as marking paper. The stylus or the means for carrying is connected to a transducer means which follows the changes in magnitude and provides an output to drive the stylus along the width of the paper in one direction when the magnitude is increasing and in the other direction when the magnitude is decreasing. In addition, either the stylus or the means for carrying the paper are connected to rotating means which rotate in one direction only and which are also driven by the output of the transducer. As the rotating means rotates in one direction only, the stylus will produce a straight line along the width of the paper when the output of the transducer is in one direction, and a straight line at an angle to the first line, when the output of the transducer is in the opposite direction.

  • Patent number: 4111042
    Abstract: A self-contained unit integrally operable in conjunction with a gas meter registers equivalent standard gas volume by correcting actual gas volume for both pressure and temperature. A magnetic couple provides a drive input to the correction unit at a rate proportional to the operational rate of the meter. Separate temperature and pressure sensitive mechanisms exposed to the gas flow each provide a linear displacement proportional to changes in their absolute condition. Respective displacement of each is supplied independently to a dual input single output multiplying mechanism from which an integrated output serves to position a limiting cam in angular correlation therewith. Position of the cam effectively modifies the drive input from the magnetic couple through a crank arrangement that drives the corrected register at a rate correlated to the integrated function of absolute pressure and temperature of the metered gas.
