Title: Fluid analyzing systems
IPC: G01N30/20
Filed: 1962-11-07
Abstract: 1,014,876. Recording-apparatus; measuring electrically. LEEDS & NORTHRUP CO. Nov. 7, 1962 [Nov. 7, 1961], No. 42133/62. Headings G1J and G1N. A cyclically operating progamming unit for selecting peak values only of a cyclically repeating electrical signal obtained from an analysing system comprises a switch-actuating cam 66 (67, 68) for each peak 76 (77, 78) adapted to select the peak values in successive run cycles and a motor 65 for driving the cams in synchronism with the repetition cycle of the signal so that each cam operates at a preset time in the cycle, having been adjusted to do so during a setting cycle in which the values of the peaks were observed. Applied to gas chromatography, a setting cycle is selected by manipulating a switch 160 so that when a start button 145 is pressed the motor 65 will drive a shaft 57 and thence the shaft 36 will drive a valve 20 to introduce a sample of gas to a column 13. The constituents of the gas pass in turn through a measuring cell 30 where electrical conductivity is sensed and compared with a reference cell 33 using a wheatstone bridge, the balancing motor 176 of which controls the movement of a pen 82 across a second sheet 75 to produce a trace showing the peaks 76, 77, 78. The cams 68.67, 66 mounted frictionally on the shaft 57 are held stationary in zero position by arms 163, 162,161 controlled by solenoids 171, 170, 169 and are released thereby to turn with the shaft 57 when switch buttons 217, 218, 219 are pressed each immediately the respective peaks 76, 77, 78 are observed. The switch 160 is then turned to select a run cycle. This switches the chart drive motor M to slow speed, lifts the pen 82 from the chart and prepares circuits to pen-selecting solenoids 109, 110 and operating solenoid 182 of a one-way clutch 177. During each cycle of operations of the cam shaft 57 a fresh sample of gas flowing through valve 20 is delivered to the column 13 and just before each peak value occurs the appropriate cam actuates its associated switches to complete the prepared circuits so that the peaks are recorded with distinctive marks to form traces such as 77a. The cams also control the insertion in the measuring circuit 95 of suitable attenuaters to make full use of the range of the recorder for each constituent and where necessary to reverse the sign of the measured signal in order to record all in the same sense. The distinctive marks are produced by insividual pens 81, 82, 83 which are brought into marking position by rocking their carrier by the selective energization of the solenoids 109,110. An alternative programmer comprises an endless recording medium such as magnetic tape, Fig. 13 (not shown) with recording and pick-up heads.
