Title: Measuring apparatus
IPC: G01R19/18
Filed: 1948-10-12
Abstract: 656,074. Voltage measurements. FOXBORO CO. Oct. 12, 1948, No. 26576. Convention date, Oct. 31, 1947. [Class 37] [Also in Group XXXVIII] The invention is described as applied to the arrangement of Specification 655,359, in which a potential to be measured, e.g. that of a thermocouple T, is compared with that of a standard source S by arranging condensers Cf, Cv to be charged over contacts 11, 21 of a vibratory switch 40 by the two respective voltages Ex, Es, the charges being compared in an electronic detector A which causes a motor M mechanically to adjust the condenser Cv until balance is achieved. The value of the condenser Cv is then a measure of the thermocouple voltage which may be recorded at R by a stylus also driven by the motor M. According to the invention the vibratory switch is provided with a further contact 41 arranged to render the electronic detector inoperative during the change-over times of the vibratory switch and so prevent spurious operation of the detector by parasitic voltages arising from the switching operations. The vibratory switch 40 is preferably operated at mains frequency and the thermocouple T is connected to the fixed contacts 12, 13 through balanced filters 132-140, 143-150, which attenuate parasitics at such frequency and provide a low impedance A.C. centre tap across the thermocouple and so an effective return connection to earth from the thermocouple circuit. Variations in temperature of the cold junction of the thermocouple are compensated by a bridge B energized from the A.C. supply 71 through a rectifier V8 and voltage stabilizer tube V9. The bridge consists of resistors 151, 153 of zero temperatureresistance coefficient and temperature-sensitive resistors 155, 157. The bridge output voltage developed across the diagonal 152-154 is applied through the vibratory switch contacts 21, 31 to the measuring condenser Cv and to a further condenser Cz which is manually adjusted for zero range setting of the measuring circuit. Temperatures below the " cold " junction temperature may be measured. The electronic detector comprises an input stage V1 having negative feed-back, the coupling of V1 to the next stage V2 being periodically broken as stated above to render the detector inoperative, by the vibratory switch contact 4. The next amplifier stage V3 is coupled to the detector 114 comprising two tubes the anodes of which are fed in antiphase from the reference A.C. source through mains transformer windings 124, 126. The grids are fed in like phase from the output of V3 so that one or other of the tubes V4, V5 conducts dependent on the sense of the amplifier input and causes a corresponding variation in the outputs of power tubes V6, V7 to drive the solenoid type motor which may be as described in Specifications 646,981 and 647,025 in the corrective sense.

Title: Oxygen steel making
IPC: C21C5/56
Filed: 1962-07-11
Abstract: <PICT:1019435/C6-C7/1> Molten iron is passed continuously through a vessel in which it is blown with air under such conditions that mainly only silicon is oxidized without the addition of any substantial amount of nitrogen to the bath.  The metal is then transferred to a second non-rotary vessel containing a refining slag, and oxygen is blown in below the slag, there being relative motion between the bath and the location at which oxygen is introduced in addition to that resulting from the oxygen injection.  This relative motion may be achieved by operating this stage as a continuous process, or, when operating as a batch process, by reciprocating the lance.  Air is introduced above the bath, at least in the second stage, to burn the carbon monoxide evolved.  A suitable form of apparatus is shown in Fig. 1, wherein molten iron charged continuously at T is blown with air by reciprocating lance 8 and is eventually discharged at 11 by means of launders 30, 31, 32 to one or more second stage vessels where it is blown with oxygen by lance 8c, finally leaving at 11a.
