Abstract: ABSTRACT OF THE DISCLOSURE              Aqueous emulsions of binders for cathodically depositable aqueous coating compositions comprising emulsions of (A) 98 to 50 percent by weight of at least one water-soluble self-crosslinking cationic resin which is water-dilutable upon partial or total neutralization with an inor-ganic or organic acid and having at least 0. 5 basic nitrogen atoms in 1000 molecular weight units and a double bond number of at least 0. 5; and (B) 2 to 50 percent by weight of a water-insoluble self-crosslinking poly-condensation resin or polymerization resin having a double bond number of at least 0.8. Optionally, the water-insoluble self-crosslinking resin can include basic character but insufficient to provide water solubility.          The emulsions have excellent stability without use of other emulsifiers even in substantially diluted form usual for electrodeposition baths. The emulsions when used in coating compositions provide films which have good adhesion characteristics, cure at relatively low temperatures and relatively short curing times to provide films having excellent resistance to water, chemicals, and corrosion.

Abstract: ABSTRACT OF THE DISCLOSURE   The present invention relates to a novel process for the treatment of thermosensitive substances and in particular for the drying of said sub-stances.  The invention, which involves a flash treatment, relates to a pro-cess for the treatment of thermosensitive substances by contacting the sub-stances in the form of at least two phases, according to which in at least one phase a spinning shaft flow with axial symmetry is formed and at least one second phase is introduced in accordance with the axis of said spinning shaft flow.  The volume elements of the first flow relative to the volume elements of the axial phase, are given a momentum such that the phase issuing from the vortex sump-type flow brings about the pulverisation of the axial phase.  This is followed by the separation of the phases obtained.  The medium resulting from this contact undergoes at least one second heat treatment. The invention is applied in particular to the treatment of food-stuffs.  The in-vention obviates the need to use a treatment temperature close to that of the substance to be treated and makes it possible to subject the treated product without deterioration to sudden heating above the thermosensitivity limit.

Abstract: RCA 71,989 GAIN CONTROL FOR A CHANGE COUPLED DEVICE                  Abstract of the Disclosure The present circuit is applicable to buried channel charge coupled devices (CCD's) of the type having an input circuit which employs a "skimming" technique for producing a charge representing an input signal.  A given amount of charge initially is present in an input potential well of the CCD and an amount of charge representing an input signal is skimmed therefrom for propagation down the CCD, leaving behind a residual charge which continuously remains in the input potential well.  The gain of the input circuit of the CCD is controlled by controlling the amount of this residual charge either in open loop fashion or by means of feedback.  A comb filter suitable for separating the luminance and chrominance components of a television signal which includes this circuit is also described.

Abstract: ABSTRACT         A method for forming strip material adapted to be cut into lengths to provide parts of fasteners is described.  The method comprises the following steps:  moving two non-fibrous polymeric strips from generally opposite directions around parallel arcuate spaced guides and away from the guides in the same direction along parallel paths; heating the polymeric strips on the spaced guides to soften them; feeding flexible, resilient polymeric monofilaments between the spaced guides from the sides thereof opposite said parallel paths and in a direction generally parallel to said parallel paths; alternately deforming the mono-filaments into a first line of U-shaped portions while pressing the first line of U-shaped portions into engagement with one of the strips and then deforming the monofilaments into another line of U-shaped portions while pressing the other line of U-shaped por-tions into engagement with the other strip to embed and bond the U-shaped portions of the monofilaments in the strips in the positions that they are pressed into engagement therewith so that lengths of the monofilaments between the U-shaped portions extend generally normally between the strips as the strips move along the parallel paths; severing the monofilaments midway between the strips to form two brush-like halves; and heating the newly severed terminal ends of the monofilaments projecting from the strips to form heads having generally hemispherical surfaces opposite the strips.

Abstract: Abstract of the Disclosure An optical scanning and encoding device for providing a print signal pulse train to an ink jet printer in which a master image, including a reference image area, is scanned along a scan line.  An optical scanner scans the master image and provides a signal which is inversely related to the print density of the image along the scan line.  An integrator inte-grates the density signal during receipt of a gating signal pulse.          A level detector detects when the integrator output has reached a predetermined level and provides a pulse to the printer and to an integrator reset circuit.  A reference level means, responsive to scanning the reference image area, provides a signal output indicative of the maximum print density in the master image.  A tachometer provides tachometer pulses at a frequency proportional to the rate at which the master image is scanned along the scan line.  Means are responsive to the output of the reference level means and to the tachometer means for providing gating signal pulses to the integrator means, which pulses are of a frequency proportional to the tachometer pulses.  Each of the gating signal pulses is inversely proportional in duration to the output o  the reference level.  The pulse signal to the printer is therefore compensated for fluctuation in the rate at which the master image is scanned and also for fluctuations in the optical path of the scanning means.

Abstract: ABSTRACT OF THE DISCLOSURE    A radio transmitter power amplifier is connected to a driver circuit whose drive power determines the output power of the power amplifier.  Direct current is supplied to the driver circuit under the control of a temperature control circuit which compares a temperature indicative voltage with a voltage indicative of the direct current drawn by the power amplifier.  If the power amplifier direct current is above a desired level for a given temperature, the control circuit reduces the direct current supplied to the driver circuit, and hence the output power of the power amplifier.  If the power amplifier direct current is below a desired level for a given temperature, the control circuit increases the direct current supplied to the driver circuit, and hence increases the output power of the power amplifier.
