Abstract: The present invention describes a method to produce high purity hydrocarbon materials from renewable sources. The produced materials are chemically indistinguishable from highly refined mineral oils and/or synthetic hydrocarbons. These renewable hydrocarbon materials can be used as a drop-in replacement for mineral and synthetic hydrocarbon base oils, process fluids, white oils in products such as lubricants, rubber, personal care, pharma.

Abstract: A solid rocket propellant includes a hydroxy-terminated caprolactone ether binder and an oxidizer. The propellant may be disposed of by contacting it with an aqueous solution of 12 N NaOH or 6 N HCl at a temperature of about 140° F. for about 24 hours to decompose the binder. Solids remaining in the solution after the binder decomposes are removed.

Abstract: A solid rocket propellant includes a binder that is a linear block co-polymer of caprolatone and tetramethylene ether and an oxidizer. The propellant may be disposed of by contacting it with an aqueous solution of 12 N NaOH or 6 N HCl at a temperature of about 140° F. for about 24 hours to decompose the binder. Solids remaining in the solution after the binder decomposes are removed.

Abstract: A converter, for converting a dual-tone multi-frequency (DTMF) signal produced by a TOUCH-TONE telephone to a 2-out-of-7 coded representation of the "dialed" number, includes an oscillator having a frequency much higher than the frequencies of the tones, a high band circuit for high band tone frequencies, and a low band circuit for low band tone frequencies. Each circuit includes a filter for passing the respective band of tone frequencies from an input terminal, a limiter for translating a received tone sine wave passed by the filter to a corresponding square wave, a counter, a switch enabled by the square wave output of the limiter for coupling the output of the oscillator to the input of the counter during a cycle of the square wave from the limiter, and a decoder for translating the resulting count in the counter to a signal on an output line representing one of the tone frequencies.

Abstract: A time division multiplex private automatic branch exchange includes a common interchange bus, and as many sampling circuits and associated recirculating shift registers as there are telephones. Two telephones are connected to each other through the bus when time-slot-determining outputs of the respective two shift registers actuate transmission gates in the respective sampling circuits. Other pairs of telephones may be connected to each other during other time slots. Additional sampling circuits and shift registers are provided to connect dial tones, ring tones, etc., over the bus to appropriate telephones in the same time division sampling fashion. All sampling connections are made under control of a computer by loading information into time slot stages of the shift registers.
