  • Process for producing substances optically transparent to infrared rays
    Patent number: 4557914
    Abstract: In order to obtain substances that are optically transparent in the infrared range, usable in the manufacture of optical fibers or radiation emitters, a metal or metalloid chalcogenide other than an oxide is produced by a double-substitution reaction between a starting chalcogen compound--particularly a hydride such as H.sub.2 S, H.sub.2 Se or H.sub.2 Te--and a salt of the desired metal or metalloid, e.g. a chloride. The starting compound and the reactant salt preferably are vaporized at a temperature below the melting point of the resulting metal chalcogenide which thereupon precipitates in the reaction chamber.

  • Digital echo-cancellation method and circuit arrangement
    Patent number: 4558187
    Abstract: A four-wire trunk line of a telephone network, operating with frequency-division multiplexing, is coupled by a hybrid coil to a local two-wire line and is provided, at a location separated from that hybrid coil by frequency modulators and demodulators, with an echo canceler connected across its receiving and transmitting branches. In order to eliminate frequency offset resulting from the incoherent modulation and demodulation, the echo canceler coacts with the phase-roll compensator comprising a phase-locking loop driven, during an acquisition phase, from a digital pilot-tone generator temporarily connected via a digital/analog converter to the receiving branch. The loop includes an analog/digital converter in the transmitting branch receiving the echo of the pilot tone due to hybrid-coil unbalance, a 90.degree.

  • Cellulosic organic solvent soluble products
    Patent number: 4557951
    Abstract: The invention provides an improved cellulosic ester or ether product with a degree of ester or ether substitution of between 2.0 and about 2.9 which is derivatized or further reacted by reaction with an acrylamide reactant to provide pendant acrylamide functionality or substituents at a degree of substitution (D.S.) of at least about 0.05 (preferably from about 0.05 to about 0.5) and to thereby provide a polymerizable organic solvent-soluble product which is insoluble in water and copolymerizable with vinyl monomers. The product is conveniently prepared by reacting said cellulose ether or ester derivative with a catalyst and the acrylamide reactant at a pH of from between about 4.2 and about 4.5. The reaction is carried out at a temperature between 80.degree. C. and 120.degree. C. for from one-half to three hours, while removing the water of reaction.

  • Portable container with interlocking funnel
    Patent number: 4557395
    Abstract: A portable, vented container for dirty oil, of the type having a small fill spout and having increased utility when used in conjunction with a funnel. A vent closure member and a funnel securing latch are integral with the funnel so that when the funnel is inverted and positioned in surmounting relation to the container, the vent closure member closes the vent and the securing latch is engaged by a fill spout cap which engagement secures the funnel against movement and hence maintains the vent closure as well. Removal of the fill spout cap releases the funnel, and positioning the funnel into its operative position relative to an automotive oil drain plug separates the vent closure portion of the funnel from the vent. An elongate extension member having a flexible medial portion is further provided.

  • Perfluorodioxole and its polymers
    Patent number: 4558141
    Abstract: Perfluoro-1,3-dioxole is a useful monomer, which polymerizes to either amorphous or liquid homopolymers and copolymerizes with tetrafluoroethylene as well as with other monomers to both crystalline and amorphous copolymers having one or more such comonomers incorporated therein. Amorphous homopolymers and copolymers of perfluoro-1,3-dioxole are useful in such applications as glazing for reactors for hydrogen fluoride reactions. Amorphous homopolymers and amorphous or crystalline copolymers form self-supporting films and can be used for coatings and linings which are inert to most chemicals and are stain and weather resistant and as dielectrics for electrical and electronic equipment. Liquid homopolymers can be used as hydraulic fluids and heat exchange media.
