HIGH PRESSURE BAROMETER Filed July 15. 1961 I .2 Sheets-Sheet l Daniel Par/Ila 1N VE N TOR.
BY WWW E United States Patent aisles"! HIGH PliEfiSURE BAROMETER Daniel Parilla, 331 S. lst St, Brooklyn, NY. Filed duly 13, 1961, Ser. No. 123,747 2 flliaims. ill. 73-45%) This invention relates to a method and apparatus for determining the direction in which fluid pressure increases from a starting reference point.
The method and apparatus of the present invention involves the detention of the direction in which pressure increases within a fluid medium. Such information readily obtainable in a unique but simple manner by the practice of the present invention, will provide a basis for charting directional pressure increases in fluid mediums in which the pressure may vary throughout. The method may therefore be invaluable for navigational purposes both in the earths atmosphere and below the surface of the earths oceans where other navigational aids are not available.
Another object of the invention, is to provide both a method and apparatus for measuring directional pressure changes in fluid mediums which may deviate from what is generally expected or theorized according to our present understanding of the physical laws of nature.
The apparatus of the present invention therefore involves the use of a high pressure barometer of any suitable type but employing a sensitive motion amplifying mechanism so that very slight changes in pressure may be detected. The inlet of the barometer is provided with a one-Way check valve arranged to permit only pressure exceeding a reference pressure to which the barometer had been exposed, to enter the barometer chamber, said one-way check valve being constantly exposed to the external fluid medium being charted for directional pressure increases. The barometer so arranged may be mounted within any suitable vehicle or missile for the purpose of directionally probing the fluid medium to be charted. Accordingly, the vehicle upon return to the starting point will have carried the barometer therewithin so that any pressure exceeding the reference pressure at the starting point may be recorded by the reading apparatus of the barometer. As a result of this procedure, those directions from the starting point in which pressure increases, may be determined.
These together with other objects and advantages which Will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
FIGURE 1 is a front elevational view of a high pressure barometer constructed and arranged in accordance with the present invention.
FIGURE 2 is a partial enlarged sectional View of the barometer illustrated in FIGURE 1.
FIGURE 3 is a partial sectional View taken substantially through a plane indicated by section line 3-3 in FlGURE 2.
FIGURE 4 is a schematic view with parts shown in section of the installation of the barometer apparatus of the present invention for use in accordance with the method of the present invention.
Referring now to the drawings in detail, it will be observed that the high pressure barometer of the present invention is generally referred to by reference numeral 1% and includes a barometer case 12 mounting a reading scale 14, the scale being designed in the illustrated example, to record pressure exceeding the reference pressure of 14.7 lbs/sq. in. The inlet 16 of the barometer is exposed to the external fluid pressure through a pressure ice trapping valve mechanism generally referred to by reference numeral 18.
Referring now to FIGURES 2 and 3, it will be observed that the barometer ill illustrated as one example, is of the aneroid type including a displaceable pressure receiving chamber Zll that is connected to the inlet 16 through which the chamber 20 is exposed to the external fiuid. The chamber 2b is therefore fixedly anchored at one end 22 to the inlet 16 and displaceable at the end 24 in both directions depending upon an increase or decrease in the pressure to which the chamber 20 is exposed. A motion amplifying mechanism 26 is therefore provided and operatively connected between the displaceable end 24 of the pressure chamber 24 and the pressure reading indicator pointer 23.
The inlet 16 to the barometer pressure chamber 29 is connected to the valve body 35) of the pressure trapping valve mechanism 13 which in turn is exposed to the external fluid by any suitable fitting 32 and conduit 34. A one-Way check valve element 36 is mounted on the valve seat of the valve mechanism 18 within the valve bore The one-Way valve element 36 is biased to a valve closing position by means of the spring element 48. It will therefore be apparent, that one side of the one-way check valve element 36 is exposed to the pressure trapped within the barometer pressure chamber while the other side thereof is exposed to the external fluid pressure. Accordingly, only external pressure exceeding the barometer chamber pressure will open the one-way check valve element 36 so as to increase the chamber pressure within the barometer. Subsequent reduction in the external pressure will however not be reflected by the barometer pressure chamber 2%, since said chamber has trapped therewithin the maximum pressure to which the external pressure may rise in excess of the reference pressure to which the charnber 29 is initially exposed.
Referring now to FlGURE 4, it will be observed that the barometer apparatus if of the present invention is mounted within a conveyance or missile 42 with the conduit 34 exposing the one-way check valve mechanism 13 to the external fluid pressure medium 44- so that the barometer apparatus ltl may record the maximum pressure exceeding the reference pressure within the fluid medium through which the missile or conveyance 42 travels. It will therefore be apparent, that should the missile be propelled from a starting point in any probing direction through the fluid medium 44, upon return of the missile to the starting point, the maximum pressure in excess of the reference pressure of the medium will have been recorded on the barometer 10. Those directions in which pressure increases, may thereby be determined. It will therefore be appreciated, that the method and apparatus of the present invention provides a simple and accurate means for verifying or measuring deviations of pressure variations of fluid mediums from that which is expected.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
What is claimed as new is as follows:
