Title: Improvements relating to tank gauge
Inventor: MAYES FRED MARSTON
IPC: G01F23/44
Filed: 1958-01-09
Abstract: 882,078. Electric selective signalling systems. SUN OIL CO. Jan. 9, 1958, No. 919/58. Class 40 (1).  In liquid level gauging apparatus wherein a reading is initiated by lifting a float 6, Fig. 1, out of the liquid, e.g. as described in Specification 882,077, variations in the tension of the float supporting tape 8 are used electrically to record the time or point of complete emergence of the float from the liquid relative to the tape movement. As described in the above mentioned Specification the tape is normally maintained taut by a known constant tensioning device 32-38, and to initiate a reading, a switch 78, Fig. 3, is momentarily closed to energize a motor 44 over a self-locking relay 76. The motor through an interrupted pulley 42 frictionally drives the tape 8 to lift the float clear of the liquid surface and then drop it back. The tape is perforated according to a binary code and its movement is sensed by phototransistors 56, 58 and recorded on a chart 106, Fig. 4, advanced synchronously with the motor drive. The pulse forms 108, 110, 112 are produced during lifting of the float and serve to indicate the liquid level; rapid pulses 116 produced by the same circuit as the float falls energize a relay 70 to break the motor circuit. According to the present invention, variations in the tension of the tape 8 cause corresponding deflections of a cantilever arm 14 carrying the tape guide pulley 12, thereby varying in correspondence the impedance of a transducer 22 energized from an oscillator 82, Fig. 3. The increase in tape tension as the float is lifted, thus increases the normal negative potential fed by a diode 86 to a condenser 92, this change of potential being passed by the condenser 92 to the grid of a normally operating thyratron relaxation oscillator 94 to stop oscillation thereof. The thyratron oscillator output is connected via condenser 104 to the recorder 104 to produce the lower trace on the chart, Fig. 4. Thus, as the chart drive starts synchronously with the lifting of the float a few oscillations 120 are produced until the increasing tape tension inhibits oscillation when the horizontal trace 122 is produced. As the float is lifted clear of the liquid the tape tension becomes constant, the condenser 92 is discharged rapidly over resistor 96, and the thyratron resumes oscillation to produce the record trace pulses 126. The point of emergence of the float from the liquid is thus indicated by the end of the horizontal trace 122, i.e. at 124. Modifications. The invention is also applicable to cases where the float is lowered into the liquid and where the " float " has a density greater than that of the liquid and passes into the liquid. Specification 882,079 also is referred to.
