Abstract: ABSTRACT OF THE DISCLOSURE The invention is a process for rendering at least part of a surface phosphorescent.  The process involves applying to the surface a composition comprising a solution of a phosphorescence activator and a soluble precon-densate.  The precondensate is obtained by a reaction between formaldehyde and an amino compound, is capable of further reaction in the absence of the phosphorescence activator to form an insoluble condensation product that does not substantially absorb ultraviolet radiation at any wavelength at which the phosphorescence activator substantially absorbs ultraviolet radia-tion and is capable of such further reaction in the presence of the phos-phorescence activator in the amount present in the solution to form a phos-phorescent insoluble condensation product.  By such further reaction there are formed in situ on the surface phosphorescent insoluble condensation products.

Abstract: Abstract of the Disclosure This invention relates to a novel process for producing pigment grade Fe203 from waste ferrous sulfate by a roasting process.  Waste ferrous sulfate is partially converted to the oxide by roasting and after elimination of soluble constituents by washing, the oxide is subjected to pigmentary calcination and then crushed and if desired, micronized.  The process produces red pigments of excellent quality which are characterized by pure tints ranging from orange-red to purplish-red with low oil absorption levels.  The pigments find a variety of uses and in view of their low toxicity, may effectively be used in foodstuffs.          The process provides a useful means to convert previously waste by-products into commercially viable products more effectively than any other prior art process.  The products thus produced exhibit excellent qualities for use as pigments.

Abstract: ULTRASONIC SHEET MATERIAL    TESTING APPARATUS              Abstract A device for testing sheet material, such as wood veneer, includes a rolling transducer for introducing ultra-sonic signals into the veneer so as to cause travel of the signals generally in the plane of the veneer.  Coupling oil filling this transducer facilitates the transmission of the signals into the veneer.  Another similar rolling transducer is provided to detect the travelling ultrasonic signals.          Each rolling transducer includes a special rim with an annular focusing ring for directing the ultrasonic signals to and from the veneer.  A timer circuit produces a signal representing the travel time taken for an ultrasonic signal to pass between the transducers.  An averaging circuit ob-tains an average of such travel times for each sheet and a grading circuit causes the sheet to be marked with a grade corresponding to the average travel time.  A signal thresh-old detector prevents travel times for detected signals of a magnitude less than a preselected minimum level from being included in the average.  Travel times for detected signals of a magnitude exceeding a noise level are blocked by a noise discriminator from being averaged.  A variable noise level circuit adjusts the magnitude of the noise level at certain times following the transmission of an ultrasonic signal into the veneer.  Detected signals having a travel time which is not between a preselected minimum and maximum time established by a time window circuit are disregarded.  A calibration signal generator provides a signal of a known and adjustable time length for use in adjusting the grade corresponding to travel times.

Abstract: ABSTRACT OF THE DISCLOSURE      To detect tampering of a kilowatt-hour meter by the connection of a bypass link across the live connection through the meter, a voltage transformer within the meter unit is coupled to this live connection so that a small voltage is induced in the live connection in opposition to the supply voltage.   The induced voltage produces a circulating current in the loop formed by the live connection and the bypass link and the transformer coupling is such that, with a bypass link of negligible resistance, the total current in the live connection is in opposite phase to the applied voltage.   By means of a current transformer,a logic unit and a microprocessor, the phase of the current in the live connection within the meter is determined and is indicated by a latched flag indicator and/or transmitted to a distant data processor by a data link.   Using a second current transformer in the return supply lead, the supply and return currents in the leads within the meter unit can be compared in the logic unit and processor to determine if the live connection is broken within the bypassed length.          By means of contacts on the housing, indication is given if the housing of the unit has been opened.
