Title: Direct current measuring circuits
IPC: G01R19/20
Filed: 1964-08-04
Abstract: 1,068,477. D. C. current measurement. W. B. ZELINA and J. L. BUCHANAN. Aug. 4, 1964 [July 29, 1963), No. 31152/64. Heading G1U. [Also in Division H3] A circuit for measuring a large D. C. current Ig incorporates a saturable transformer having bias, feedback and control windings wound on square loop (ferrite) material in addition to a one turn primary winding carrying the D. C. current Ig. The control winding Nc is connected to an npn transistor T 1  and a resistor R o , the voltage drop across which is determined to provide a measure of Ig, and a diode D 2  is connected across the winding and resistor. The feedback winding  N F  is connected in series with a diode D 1  to the transistor base, and the bias winding N B  is connected across the circuit D. C. supply Voc in series with a potential divider R 1 , R 2 . A similar alternative circuit incorporating a pnp transistor is also described Fig. 4 (not shown). In operation, with zero current Ig, current flows as shown through the bias winding N B  to bias the flux of the transformer to negative saturation. The transistor T1 is biased into conduction by its base potential, so that a large current flows through the winding Nc to cause the flux in the core to move towards positive saturation. The reduced voltage in the feedback winding N F  drives the transistor base more positive, and the transformer core is driven firmly into positive saturation. When this occurs, a large spike of current flows because the reactive impedance of the transformer disappears, driving the transformer core far into saturation. The loss of induced voltage in the feedback winding causes the transistor to conduct less, and the  flux in the transformer starts back negatively. This induces a small voltage in the winding NF which tends to turn off the transistor. Regenerative action cause the transistor to turn off completely, and the negative ampere turns of the winding N B  drive the flux of the transformer toward negative saturation. When this occurs, the induced voltage in Ny disappears, the transistor becomes partially conductive and the cycle starts again. It is shown in the Specification that when the bias current I b  in the bias winding NB is supported by a current to be measured I g , then (approximately).  where I c  is the current in the control winding. Since I b  is fixed, I c  will be proportional to  I g , and is measured as the voltage appearing across the load resistor R o

Abstract: 1402342 Ion exchange process AVCO CORP 5 July 1972 [8 July 1971] 31504/72 Heading B1J A process for isolating the flow of a first fluid flowing at a first rate in a first zone of a column from the flow of a second fluid flowing at a second rate in a second zone of said column in which column a packed porous bed of solid material comprises the steps of permitting a controlled portion comprising at least a part of said first fluid to flow from said first zone toward said second zone at a fourth rate; permitting a controlled portion comprising at least a part of said second fluid to flow toward said first zone at a fifth rate; independently controlling said fourth and said fifth flow rates so as to permit the removal of said controlled portions of said first and second fluids simultaneously at a position intermediate said first and second zones, thereby forming an isolation zone between said first and said second zones to prevent any of said first fluid from entering said second zone and any of said second fluid from entering said first zone. The process is described with reference to an ion-exchange process in which it is necessary to keep separate the untreated liquid and the regenerant. As shown, "isolation zones" 41 and 42 separate the regeneration zone 12 from the reaction zone 11 and the. driver zone 13. In these isolation zones liquid enters from opposite directions and leaves through a port in the side of the column, pressures being adjusted by means of pumps 17 and 33 and throttle valves 21, 26 and 38 so that "isolation crowns" 39, 40 are formed in the zones and the adjacent zones are effectively isolated. In the described embodiment liquid to be treated enters at 16 and leaves via valve 21; regenerant solution enters at 27 and leaves via port 36; the resin bed moves continuously upward through the regeneration zone and the reaction zone and is recycled, via the pump 33 and the driver zone 13.

The screens and the light receiving surfaces may be of various shapes (Fig. 5, not shown). Light from the various sources produces interference patterns on the receiving surfaces as viewed from 12 and these patterns can be varied by modifying the flux from each source by means of an apparatus 10 in accordance with the variations of an external phenomenon such as the sound of music. The device can thus be used to enhance the listening to music. It can also be used in learning music; in the orchestration of music and for developing and learning language.

In welding the edges of a longitudinal gap in metal tubing, the edges are brought together at a weld point and currents are caused to flow in the edges in advance of the weld point by an induction coil, a body of magnetic material is mounted within the tubing in the portion thereof in which the currents are induced and/or a split metal shoe of higher electrical conductivity than the tubing metal is arranged about the tubing with the edges of the split connected to the edges of the tubing and the frequency of excitation of the coil at least 50 kc. per sec. is such that the ratio of the thickness of the tubing wall to the depth of penetration of currents in the wall is at least 2.5 whereby power losses interiorly of the tubing are reduced. The depth of penetration of currents decreases with increase of frequency and is dependent also on the resistivity and permeability of the tube material. A tube 10, Fig. 4, is passed between squeeze rolls 15, 16 where the edges 12, 14 heated by a single turn induction coil 17 supplied at a frequency of at least 100 kc. per sec. surrounding the tube are both welded at point w.
