Abstract: Abstract of the Disclosure There is disclosed a method and apparatus for quickly and accurately measuring selected characteristics of a fluid.  Particular applications to the printed circuit industry is described in which the concentration of a chemical in a solution is monitored and maintained at a preselected level.  Portions of the solution are continually pumped through a microwave sensor that senses the attenuation of the microwave radiation as the solution passes through a sensor. The attenuated signal detected beyond the solution is compared to the signal as detected in the sensor in advance of the solution.  If the signals differ by an amount different from the initial amount, the concentration of the chemical is adjusted accordingly.  Circuitry is also provided to accommodate differences in the microwave detectors' responses to microwave radiation as a function of temperature, and delays in dissolving the chemical in solution.  Alarm signals are generated if the concentration of the chemical in the solution differs from a preselected concentration by more than a preselected amount and chemicals are added by pumps if the concentration drops below selected levels.

Abstract: TERMINAL VOLTAGE LIMIT REGULATOR  FOR A LOAD COMMUTATED INVERTER   ABSTRACT OF THE DISCLOSURE A control system for a load commutated inverter AC synchronous motor drive provides an operational shift-in the event of an increase in  motor terminal voltage VTERM above a preselected reference level.  Under such an increase in terminal voltage, control is transferred from a condition where torque is controlled by current and the terminal voltage is uncontrolled to a condition where the load current, e.g., the DC link IL flowing between a source side thyristor converter (AC to DC) 12 and a load side thyristor inverter (DC to AC) 14 is utilized to control the motor terminal voltage while the firing angle of the thyristor inverter 14 is used to control the motor torque.  This involves increas-ing the minimum load or motor drive current for a desired torque while adjusting the inverter firing angle from a previous value, so that the desired torque is provided than before.  Such an operational shift, in effect, uses a component of the load current to demagnetize the motor field in order to maintain the motor terminal voltage at an acceptable level.

Abstract: A method of measuring the quantities of material in a first coating layer applied to cardboard or an equivalent base material as well as in a second coating layer applied to said first coating layer, comprises the steps of directing a primary X-ray radiation against the second coating layer so as to excite a characteristic fluorescence radiation in the first coating layer and measuring the intensity of said fluorescence radiation be means of a detector placed above said second coating layer, whereby the measurement of the quantity of material in the second coating layer is based on the absorption of the primary X-ray radiation and the fluorescence radiation while traveling through the second coating layer. The measurements in connection with the process of coating are carried out by measuring the quantity of material in the first coating layer before applying the second coating layer by irradiating the first coating layer with a primary X-ray radiation so as to excite a characteristic fluorescence radiation in the first coating layer itself and by measuring the intensity of this fluorescence radiation with a detector. The quantity of material in the second coating layer is measured after the application of this layer to the first coating layer by utilizing the value of the intensity of the fluorescence radiation from the first coating layer as measured before the application of said second coating layer.

Abstract: ABSTRACT OF THE DISCLOSURE           A carton sealing machine for sealing cartons in which a clutch is provided to connect a pair of oppositely disposed conveyor belts for movement thereof from a driving motor.  The clutch transmits motion from a driving motor to a pair of approachable  conveyor belts, and three sensors are successively arranged along a sealing area to sense the posi-tion of advancing cartons advancing through the sealing area; the first sensor is positioned at the inlet of the sealing area to cause a lifting of the sealing head from a lowered rest position, the second sensor is slightly advanced along the path in the sealing area with respect to the first sensor to cause the conveyor belts to move to approach each other in a direction transverse to the direction of carton movement, from a removed rest position, and a third sensor is positioned at the outlet of the sealing area to move the conveyor belts away from the sides of an engaged carton to return the coveyor belts to the removed rest position; and the clutch and the third sensor are operatively connected to cause the disconnec-tion of a driving motor from the conveyor belts for the subse-quent stopping thereof, to thereby avoid accidents as a result fo conveyor belt movement between sealing operations for sequential cartons.  A releasable friction is included in the motion transmission means interposed between the conveying belts and their driving motor.  A sensor placed at the outlet of the sealing area detects the disengagement of a carton from said area and then controls the release of the friction for the consequent stop of the belts.  This has the object to avoid accidents due to the belt movement between a sealing opeation and the successive one.

Abstract: Title of the Invention Forsterite-Carbon Refractory Abstract of the Disclosure The invention relates to forsterite-carbon refractory.    The inside wall of the molten metal container, such as molten pig iron vessel, torpedo car, a molten steel ladle, ladle refinery, tundish, etc. has been lined with refractory so as to impart it slag resistance.      With the introduction of new processes, such as dephos-phorizing, desilicifying or continuous casting, degassing refining, etc., as a result of the recent development of the pig iron and steel producing technology, the lining refrac-tory of the molten metal container, and particularly of the part thereof most susceptible to the direct attack of the slag, for example, the slag line, charging wall, charging part of the bottom, slagging wall, etc.,is now found to have a disadvantage in that its useful life is greatly reduced by the structural spalling due to slag infiltration.      After a series of tests of the lining refractory of the molten metal container having long lining life even under severe operational conditions and in an oxidizing atmosphere, the inventors concerned have accomplished the invention, i.e. forsterite-carbon refractory comprising forsterite material 5-50 weight %, carbonaceous material 5-30 weight %, silicon carbide 0.5-10 weight %, the residual part consisting of magnesia refractory materials.

Abstract: Type A, especially type 4A zeolites are well adapted as detergent builders, said zeolites comprising (i) primary particles having a mean particle diameter ranging from 0.1 to 10 mu , (ii) a cation exchange capacity in excess of about 100 mg CaCO3/g of anhydrous material, and (iii) a rate constant, relative to the surface area of the zeolite per liter of wash solution, in excess of about 0.15 s-1 lm-2. The builders are prepared by first determining the value of the rate constant for a given zeolite sample. Since a higher rate constant value corresponds to a lower degree of salt incrustation on fabrics, only those zeolites having a value above the predetermined minimum will be incorporated into detergents. Thus, zeolites otherwise appearing identical can be differentiated, with only those not causing high levels of incrustation being selected.
