  • Patent number: 5604292
    Abstract: Novel conjugated amino substituted phenylene polymers are disclosed having on-linear optical properties, and which can be converted to electrically conductive polymers. Such polymers are produced by reacting a novel bis-cycloalkylene sulfonium salt of 2,5,N,N-tetramethylaniline hydrochloride, such as 2,5-(N,N-dimethyl)aniline hydrochloride dimethylene bis-(tetramethylene sulfonium chloride) with alkali metal hydroxide to form a cycloalkylene sulfonium salt precursor polymer, and then heating the precursor polymer under conditions to produce the amino substituted phenylene vinylene polymer, such as poly(2-(N,N-dimethylamino) phenylene vinylene). The polymers can also be made directly by treatment of the bis chlormethyl dimethyl aniline hydrochloride derivative with alkali metal alkoxide.

  • Patent number: 5604438
    Abstract: A high voltage differential is applied across two separated electrodes by a oltage supply. Between these electrodes is located a sample of the solid propellant or other energetic material. The voltage differential across the electrodes generates a spark of measurable voltage, current and time duration in the sample in order to foretell at what energy level sustained ignition of the sample occurs. This spark is measured by a voltage monitor which, upon reaching a predetermined level, sends a signal to a short-circuiting network. The short-circuiting network, after a predetermined time delay, shorts the electrical path across the electrodes thereby removing the voltage differential across the sample and ending the ignition test. An operator is then able to determine visually whether or not the spark of known voltage, current and time duration has created sustained ignition of the sample material.

  • Patent number: 5600089
    Abstract: Elastomers having a polyurethane binder are formed from a mixture including tetrastar polyethylene oxide polyol with a molecular weight of at least 16000 daltons and a plasticizer present in a ratio of at least five parts by weight to one part of the polyol and provide high tensile strength, extreme elongation, great flexibility, and absence of voids. Energetic elastomers use a nitrate ester plasticizer with a curative having a functionality of at least three and an NCO/OH equivalent ratio of about 2.5 and may include an energetic particulate filler. Inert elastomers use a non-volatile ester plasticizer, as dimethyl phthalate, with a curative having a functionality of two and an NCO/OH equivalent ratio not over 2.0.

  • Patent number: 5596327
    Abstract: A radar encoder comprising a delta modulation circuit which receives analog adar video data from a radar and then converts the data to digitized NRZL video data. The radar encoder also has an encoder circuit which receives the digitized NRZL video data as well as a trigger pulse signal and analog synchro signals from the radar. The synchro signals are provided to a Synchro-to-Digital Converter which converts the synchro signals to sixteen digital synchro data bits which are then latched into the converter. The synchro data bits are next parallel transferred to a pair of shift registers and then clocked in a serial format to a multiplexer. The multiplexer also receives the digitized NRZL video data supplied to the encoder circuit. A state machine, in response to the trigger pulse signal, generates control signals to latch the synchro data bits into the converter and then effect the parallel transfer of the synchro data bits from the converter to the shift registers.

  • Patent number: 5596405
    Abstract: A portable apparatus for continuous real-time measurement of airborne met, comprising an isokinetic sampler, a sample line, a sampling interface device, a pump, and an inductively coupled plasma atomic emission spectrometry (ICP-AES). A method for measurement of airborne metals by use of such an apparatus is also described, in which the sampling interface device accommodates the high, continuous sample collection flow-rates necessary for isokinetic sampling while at the same time permits sample air to be introduced into the plasma at preferred moderate flow-rates. A method for field standardization of the ICP-AES is also described whereby a relationship between aqueous solutions of metals and their aerosol counterparts is established, thus later allowing the field use of the aqueous metal solutions to simulate a particular range of airborne metal concentrations.

  • Patent number: 5587972
    Abstract: A control signal generator for generating a plurality of control and timing ignals which are supplied to a scan converter. The control and timing signals are utilized by the logic elements of the scan converter to process the incoming pixel data from a missile's seeker allowing the data to be supplied to a video monitor for viewing. The control signal generator includes a state machine which generates four state variable signals and a cycle counter which generates a binary count thirty one signal which allows the state machine to cycle through six predetermined states until the scan converter completes processing of incoming pixel data from each detector of the missile's seeker. The count thirty one signal and the four state variable signals are decoded by five decoders which generate the timing and control signals for the logic elements of the scan converter.
