Title: Improvements in voltage measuring arrangements
IPC: G01R19/10
Filed: 1931-01-12
Abstract: 363,165. Telephone and like transmission measurements. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. Jan. 12, 1931, No. 1054. Convention date, Jan. 14, 1930. [Class 37.] In an arrangement for comparative voltage measurements, particularly transmission level measurements in telephone lines, a valve voltmeter V is alternately connected to the voltage to be measured over the contacts of a two-way switch O and through an artificial line or potentiometer to an electron valve amplifier F controlled by the voltage to be measured. The voltage V is applied between the terminals a-a to which are connected a high resistance potentiometer P<1> and a resistance R<1> in parallel with an inductance D. A second potentiometer P<2> in series with a resistance R<2> is connected in the output circuit of the amplifier F in series with an adjustable resistance S and thermo-couple T connected to a galvanometer G<2>. The potentiometers P<1>, P<2> and the mid-point of the inductance D are grounded at j and connected to one terminal of the input of the amplifier and the potentiometer P<1> is also connected to the other input terminal of the amplifier and to the switch 0 to which the potentiometer P<2> is also connected. The potentiometer P<1> is adjusted to a voltage Vx<1> giving a suitable reading on the galvanometer G<1> of the valve voltmeter and the voltage Vo across the potentiometer P<2> is adjusted to a known value by the resistance S and the galvanometer G<2>. The potentiometer P<2> is now connected to the voltmeter V and varied until the reading is the same as that obtained with the voltage Vx<1> in which case Vo<1>=Vx<1> and the voltage Vx is obtained in terms of Vo and the readings of the potentiometers P<1>, P<2> which are graduated directly in neper. The voltage Vo may be adjusted so that Voe-k = 0À775 volts, where k is a constant, in which case the sum of the readings of the two potentiometers P<1>, P<2> gives the transmission level in neper. Corresponding halfwaves of the applied and reference voltages are thus rectified in the valve voltmeter. In a modification, for loop attenuation, amplification ratio and resistance measurements, switching means is provided whereby the amplifier F is disconnected and the input and output voltages to the loop are composed by the voltmeter V using the potentiometers P<1>, P<2> in the same manner as for transmission level measurements.

Title: Dead-time simulator for industrial process control apparatus
IPC: F15C4/00
Filed: 1963-01-09
Abstract: 993,914. Fluid-pressure servomotor systems. FOXBORO CO. Jan. 9,1963 [Jan. 25,1962], No. 1080/63. Heading G3P. Apparatus for introducing a time delay of up to 10 minutes in the response of a pneumatic controller to allow for the period or "dead time" between a change of a condition at one stage in an industrial process and the consequent change at a later stage comprises a phase-shifting device 26 the output of which is connected with an integrating device 28 which develops a delayed output signal corresponding to the time integral of the output produced by the phase-shifting device. The invention is described in connection with apparatus in which feed stock flows into a processing tank from which "top" and "bottom" products are obtained and in which any change in the rate of inflow is required to cause, after an interval, a corresponding change in the rate of outflow of the "top" product. A pneumatic signal from an inflow detector is fed to a bellows 30 which rocks a lever 32 about a pivot 34 to adjust the pressure in a nozzle 36 which, through a relay 38, varies the pressure in a bellows 40 in the opposite sense to the variation in the bellows 30. After an interval, the variation in the bellows 30 becomes effective through a resistance-capacity 44 in bellows 46; 48 which bring the pressure in the bellows 40 into phase with that in the bellows 30. The integrator, whose input to a bellows 52 is obtained from the bellows 40 through a resistance-capacity 50, has a lever 54 pivoted at 56 and controlling the pressure in a nozzle 58 which, through a relay 60, determines the pressure in a negative feedback bellows 62. The relay output is also applied, after a time delay caused by resistance-capacity elements 64, 78, to a positive feedback bellows 66 and after passing through a 1: booster 72 and further time delay elements 70 to a negative feedback bellows 68. The final output, which is fed through time delay elements 74 to a controller for a valve in the "top" product conduit, does not emerge during the period over which the output from the device 26 changes from being out of phase to being in phase with the flow signal applied to the bellows 30, as the time integral of such output is zero, nor does it emerge for some time after the phase change has been completed due to the various delay devices in the integrator 28.
