Abstract: ABSTRACT      IMPROVED PIGMENTS AND THEIR PREPARATION   Titanium dioxide pigment  having a high durability when used in paints comprises a particulate core of rutile titanium dioxide having an inner coating of dense amorphous silica on which is carried an outer coating of a hydrous oxide of zirconium.  Optionally the pigment has an outer coating of a hydrous oxide of aluminium.    The amount of dense amorphous silica is up to 12% by weight expressed as SiO2 and the amount of hydrous oxide of zirconium is up to 5% expressed as ZrO2 on the weight of TiO2.  The outer coating of hydrous oxide of aluminium can be present in an amount of up to 6% by weight expressed as Al2O3 on the weight of TiO2.    A combination of these coatings has been found to be extremely advantageous in producing a paint containing the pigment having a very good durability and resistance to weathering.

Abstract: Abstract A power-factor regulator for a three phase line is described.  The regulator comprises a delta connected circuit comprising three series circuits connected between the phases.  Each series circuit comprises a series capa-citor, optional series reactor coil and a parallel combination of a diode connected in reverse parallel relation across a thyristor.  Each thyristor is controlled so that the capacitor is initially charged to about maximum line voltage when the load is open and thereafter the thyristor is switched to close the capacitor and discharge it at the time the line voltage is at or around its maximum after the load is closed.  The invention mitigates the effect of impulse waves and eliminates the need for discharge coils.  Instead of being connected in the delta circuit the reactor coils may be connected in series between the phases of the line and the delta circuit in the conventional way but to achieve the same wave reforming ability the reactor values have to be doubled when the conventional connection is used.

Abstract: METHOD OF SEALING INTERFACES OF BEARING SURFACES TO STEEL BARRELS OF PISTON PUMPS            ABSTRACT OF THE DISCLOSURE          The method of contemporaneously sealing interfaces of bearing surfaces for valve faces and cylinder linings in a steel rotary cylindrical barrel having a plurality of longitudinal bores extending through the barrel longitudinally from one end to the other, each of the bores having a restricted diameter intermediate portion connecting a valve surface area at one end of the barrel with a cylinder are extending to the other end. An insert of bearing material is placed in both ends of the bore and a cap secured over a lower end adjoining the cylinder bore.  A removeable carbon hot top is placed over the other end of the barrel.  The barrel and its assembly is heated in a metalurical furnace for 90 minutes at 1925°F, disposed vertically, with the cap at the bottom and is then removed from the furnace and cooled with the cap resting on a bronze pedestal to cause the bearing material to slowly solidify from the bottom up, and to cause gases to rise through the restricted area of the bore as the barrel cools.   When the temperature is below 1000°F, the hot top is removed to permit solidification of the bearing material in the upper valve area.

Abstract: ABSTRACT       Suction tube packages comprising suction tubes arranged in succession, which are placed between two weblike plastic strips sealed to one another, are used for the application of suction tubes to packing containers for e.g. juice or milk.  The weblike suction tube packages are provided with transverse cuts between each individual suction tube envelope which facilitate the sep-eration of individual envelopes on application of the suction tube envelopes to the packing container, but increase the risk of unintentional detachment of envelopes from the suction tube package.  This risk can be appreciably reduced if the suction tube package is provided between, or on the outside of, the two long strips sealed to one another with two substantially parallel tapes      situated at some distance from one another.  The tapes         absorb the stresses the suction tube strip is sub-jected to in longitudinal direction and thus prevent them from causing a lengthening of the cuts present in the suction tube package as a result of which individual suction tube envelopes could be separated unintentionally or the cuts could extend into and damage the tight suction tube envelopes.

Abstract: METHOD AND APPARATUS FOR MEASURING FLOW               ABSTRACT OF THE DISCLOSURE Flow, and in particular nonuniform flow, as in a vascular system, is measured by applying a stochas-tic excitation signal to a system inlet which results in a measurable output signal at a downstream system outlet.   Flow rate may be extracted by cross-correlating the excitation signal and the output signal.  Calibration may be effected by conservation of mass principles whereby quantity type parameters are related to concen-tration type parameters.  The stochastic signal has the characteristics of white noise, such that simplified spread spectral detection and signal extraction tech-niques may be employed to recover the desired intelli-gence.
