Patent GB-310539-A (GB)
IPC: H03F1/50
Filed: 1929-04-25
Abstract: 310,539. Asch, E. April 28, 1928, [Convention, date]. Addition to 300,511. Thermionic valve circuits.-An amplifier as claimed in the parent Specification is employed for indicating and measuring alternating current voltages, particularly of high frequency. As shown in Fig. 1, the high-frequency voltage to be measured is applied to the grid of a valve l<1> through a transformer t. In series with the anode of the valves l<1> is a very high resistance w, the anode being connected to the grid of the second valve l<2>, in the output circuit of which is a continuous current measuring instrument or relay a. By adjusting the grid bias of the valve l<1>, as by varying a resistance r<1>, the variation in the continuous current in the output circuit is rendered approximately inversely proportional to the incoming high-frequency voltage. To obtain direct proportionality, an odd number of valves, such as three or five, may be employed. For measuring low-frequency voltages, the capacity load of the first valve is increased by a condenser c. In the arrangement shown in Fig. 3, the ammeter a is adjusted to a definite value by regulating the grid bias of the first valve l<1> by varying the resistance r<1>. A reading is then taken on a voltmeter i. The alternating- current voltage to be measured is then applied and the resistance r<1> is again regulated until the ammeter a indicates the same current as before. The variation of grid bias is then proportional to the supplied alternating-current voltage, and may be read on the voltmeter i or on a scale provided with the resistance r<1>. To avoid errors due to variation in the filament current, a glow-discharge lamp u and a resistance v are inserted in series with the cathode of the valve l<1>. In the arrangement shown in Fig. 1, an automatically adjustable resistance r<2>, such as a tungsten filament in an atmosphere of nitrogen, is inserted in the heating circuit. Fig. 2 shows means for disconnecting a telephonic receiver p when spark transmission received by an aerial y stops, the output circuit of the valve l<2> containing a relay q having a permanently magnetized core surrounded by a demagnetizing winding.

Title: Apparatus for determining the gas content of drilling muds
IPC: E21B21/06
Filed: 1973-03-20
Abstract: 1399767 Determining the gas content of drilling muds WESTON INSTRUMENTS Inc. 20 March 1973 [20 March 1972] 13221/73 Heading G1S Drilling mud is circulated by a pump 22, Fig.1, through tubes 23, 24 and kelly 17 to the bottom of a borehole to cool the drill 20 and carry away the cuttings to a trough 27 and mud pit 28. It is necessary, in order to prevent blowouts from occurring, to regulate the mud density and firstly to determine the amount of entrained gas in the mud by the apparatus of Fig.2. By moving a rotary control switch 77 a solenoid 65 a valve 59 is operated to allow pressure fluid to retract the piston 52 and cause the connected piston 37 to suck mud from the borehole into a space 31 constituted by the cylinder 36, 43 and their connecting pipe 45. The piston 44 is then operated by a similar actuator and valve mechanism 48 to move to the extended position 78 to extend the chamber 31 and reduce the pressure of mixed liquid and gas therein to a predetermined minimum but precise value which is known to be higher than the saturation pressure of the sample. The percentage of gas contained in a gas bearing sample can be computed from a given equation involving piston area, volume of mud sample, initial and final pressures, and the distance the piston 44 is extended as measured by a transducer 80 and indicated on a recorder 81. Thereafter the rotary switch 77 is advanced again to return the pistons 37, 44 and discharge the mud sample back into the trough 27 and purge the gas sample through an inverted gas collection chamber 84 and gas analysis device 87. The purged gas collects in the upper portion of the chamber 84 and causes the float operated valve 85 to open and flush water through the chamber 31.
