Abstract: METHOD AND APPARATUS FOR ADJUSTING THE                VELOCITY OF INK DROPS IN AN                        INK JET PRINTER                 ABSTRACT OF THE DISCLOSURE    A servo system for adjusting the velocity of ink drops in a magnetic ink jet printer has a coarse control loop for making coarse increment adjustments to the pump which supplies ink under pressure to a nozzle and a fine control loop for making fine increment adjustments to the pressure of said pump.  The velocity of the drops is determined by a pair of drop sensors located one drop wavelength apart at a fixed distance from the drop generation point.  The direc-tion of any phase error between pairs of drops is used to generate direction control signals applied to the coarse control loop until a reversal in phase error occurs.  A toggle control allows the coarse control loop to make coarse adjustments in pump pressure around a null point velocity before switching direction control signals to the fine control loop.

Abstract: ABSTRACT           Asphalt roofing material is made fire-retardant by inclusion of a layer of intumescable hydrated soluble silicate particles.  Preferred soluble silicate particles carry a protective moisture-resistant coating which increases the life of the roofing material, and also makes possible convenient manufacture of the particles.  The protective coating includes a metal cation capable of reacting with the silicate ion of the core particle to form a reaction product that is less soluble than the core particle.  The reaction is believed to seal any openings in the protective coating, thereby lengthening the effective life of the coating.  Besides utility in roofing materials, the coated particles are useful as fire-retardant additives in many other products, including polymeric articles, sheet materials, coating compositions, etc.

Abstract: COLOR TELEVISION RECEIVING SYSTEM UTILIZING INFERRED HIGH FREQUENCY SIGNAL COMPONENTS TO REDUCE COLOR INFIDELITIES IN REGIONS OF HIGH COLOR SATURATION                     ABSTRACT OF THE DISCLOSURE         A color television receiving system for NTSC-type signals is provided with signal processing circuitry and methods for reducing the visibility of color infidelities, such as over-modulation, rectification, desaturation, and inadequate highs, which are visible in regions of high color saturation. Such infidelities are substantially reduced by effectively supple-menting either the chrominance or the primary color signals with inferred high frequency chrominance components derived from signal information discovered to be inherently available in NTSC-type signals and their implicit constraints.  Specifically, it has been found that in regions of high color saturation, high frequency chrominance components can be scaled from the high frequency portion of the received monochrome signal in accordance with the respective ratios of the value of the received reduced bandwidth chrominance signal to the value of a comparable low frequency component of the received monochrome signal,  Alternatively, inferred high frequency primary color components can be analogously derived.  A variety of specific circuit embodiments and methods can be used to derive suitable inferred high frequency components.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates generally to improvements in fluid flow control system for parenteral administration of medical liquids. Positive pressure infusion pumps of the syringe type are known.  How-ever, since a portion of each operating cycle with such syringe type pumps is concerned with filling the syringe through an intake line, rather than delivering fluid to the patient in a pumping mode, the accuracy of such devices tends to fall off, particularly at very high flow rates, where the fill stroke period is of significantly large duration relative to the pump stroke period.  The present invention overcomes this deficiency by providing a system for fluid flow con-trol utilizing a syringe pump operated by a stepping motor to repetitively fill and empty a syringe cartridge over a plurality of operational cycles of successive fill stroke and pump stroke periods. The stepping motor is driven by electrical drive pulses from a digital pulse generation and control system.  Means are provided for maintaining a proportional relationship between the preselected pumping rate and the actual fluid flow pumping rate over each complete cycle of successive fill and pump strokes, the motor drive pulse frequency during each pump stroke is automatically increased to compensate for the time lost during each fill stroke.  A detection device is provided which responds to the lack of a prescribed number of accumulated drops detected in the intake line at the end of a fill stroke.

Granted: 1982-04-20
Abstract: ABSTRACT A sub-audible in-band tone system is disclosed for identifying an FM stereophonic radio broadcast which is specially encoded, as with dynamic range improvement encoding or quadraphonic encoding, for example. A constant frequency pilot tone is added at a low level (e.g. at -70dB) to the transmitted signal at or near the upper frequency limit of the audio frequency spectrum (15 kHz).  the audio spectrum is not notched or other-wise altered to accommodate the tone.  FM stereophonic receivers detect the pilot tone by heterodyning the received tone with a stable mixing signal at 15.2 kHz derived from the 19 kHz FM stereo pilot tone.  The shifted frequency tone is passed to a low frequency narrow band detector which can control a visual display and switch in appropriate signal decoding circuitry when the tone is detected.

Abstract: Abstract of the Disclosure A memory system adapted to receive a radio frequency signal and produce a signal having a frequency related to the frequency of the received signal for an extended, predetermined period of time.  The received signal is heterodyned to an intermediate frequency signal.  The intermediate frequency signal is sampled and digitized by an analog-to-digital converter.  One bit of each digitized sample has a logic state related to the polarity of the intermediate frequency signal.  The bits associated with the samples are stored for a time interval beginning at a time the intermediate frequency signal changes polarity with a predetermined sense, i.e. the start of a complete cycle of the signal.  A control signal is produced providing an indication of the portion of the bits stored in the shift register at the end of the time interval which is associated with complete cycles of the stored signal and the portion of the stored bits which is associated with an incomplete cycle of the stored signal.  In response to the control signal only the portion of the stored data associated with complete cycles of the signal is recycled in the shift register. With such arrangement the recycled data, which is used to generate the signal having extended time duration, is produced with minimum phase discontinuity.

Abstract: Abstract of the Disclosure A liquid melt becomes converted to crystalline from at a particular temperature either spontaneously or when artificially nucleated.  The liquid releases heat at crystallization.  If the liquid is in a supercooled state when it begins to crystallize, its temperature will rise from the particular temperature at which it is nucleated.        Another liquid material is mixed with the liquid to be crystallized.  The liquid additive has properties of forming a metastable solid together with the crystallizing material.  When the liquid additive exsolves, the crystalline aggregate is weakened and is easily decomposed into fragments of small size.  The liquid additive materials may include monohydric alcohols, diols and triols.  The liquid additive material may be included in the liquid to be crystallized, in small amounts, amounts to two percent (2%) to five percent (5%) being typical.  The amount and relative metastability of the liquid additive material in the solution contributes to control of the size of the crystals which are ultimately produced when the supercooled fluid crystallizes.  A small amount of surface active material may also be included to modify the character-istics of the metastable solid solution, the exsolution process, and the texture of the exsolved crystal aggregate.     * * * * * * * * * * *
