Abstract: ABSTRACT OF THE DISCLOSURE   A feed forward system coupled with a feed back system is used to control  the efficiency of combustion of fuel in a furnace.  The feed forward system has sensors to measure the fuel flow rate and the type and quality of the fuel.  The measurement of the sensors is used to calculate the theoretical oxygen flow rate needed to combust the fuel.  The theoretical oxygen flow rate and an excess oxygen level are used to determine the actual air flow rate, which is used to control the air input to the furnace.  The feedback system has a sensor to detect combustibles near the exhaust of the furnace.  The measurement of the combustible sensor is used to control the excess oxygen level.  In a preferred embodiment, another sensor, an oxygen sensor, is placed near the exhaust of the furnace.  The oxygen sensor provides a dynamic check on the actual amount of excess oxygen level within the furnace.       Finally, the oxygen sensor is also used as a safety device in providing redundancy to the combustible sensor.

Abstract: TELEPHONE MULTILINE AUTOMATIC VOICE ANSWER SYSTEM     Abstract of the Disclosure A telephone multiline inquiry voice answer system is realized by employing a minicomputer system. Predetermined voice signals are digitally encoded and stored in a disk memory.  In response to requests from one or more of the telephone lines the computer central processor determines which digital words are required from the disk to form a desired response message.  The digital words are read from the disk to word buffers in dedicated storage stages in one or more storage units in a random access memory.  Each storage units is assigned to a "fixed" number of output lines while each storage stage is assigned to a particular output line.  A direct memory access output multiplexer is employed to read the digital words from loaded word buffers in the storage stages to corresponding output lines without substantial processor control.  To this end, the multiplexer includes output modules in conjunction with a common control module to effect the desired transfer.  Each output module monitors address signals transmitted in the computer system when digital words are transferred from the disk memory to the word buffers in a particular storage units to detect which ones of the storage stage include buffers that have been loaded with digital words.  Then control signals are generated by the multiplexer which  are employed - i -to effect reading the digital words from the buffers in a prescribed sequence of read intervals to corresponding requesting lines without programmed intervention of the processor.  Efficiency of the multiplexer is enhanced by employing multiple words transfers during each read interval which may vary in numbers from interval to interval in reading the digital words from loaded ones of the buffers in the random access memory storage stages read intervals.

Abstract: AMYLASE DETERMINATION        Abstract A method for the determination of amylase, based on the cleavage of colorimetric, ultraviolet absorbing or fluorometric substances, commonly referred to as chromogenic substances as p-nitrophenol derivatives of oligo-saccharides of chain length 4-10 glucose units.  Oligosaccharides of this chain length are resistant to cleavage by .alpha. and/or .beta.-glycosidase and contain endo-.alpha.-1,4 linkages which are required for amylase activity.  Cleavage of the .alpha.-1,4 bonds by amylase produces smaller fragments which are acted uponby .alpha.-glucosidage and/or .beta.-glucosidase to liberate a chromophore.  The rate of appearance of the chromophore is proportional to amylase activity and lends itself to either rate or endpoint determinations.  The qualitative or quantitative measurement of amylase concentrations in a sample is useful in medical diagnosis.
