Abstract: TITLE             METHOD AND APPARATUS FOR MEASURING THE  AMOUNT OF COMBUSTIBLES PRESENT IN THE       GASEOUS BY-PRODUCTS OF A    COMBUSTION PROCESS                   ABSTRACT OF THE DISCLOSURE           A detector bridge circuit and a reference bridge circuit receive input signals from a regulated power source and generate output signals through feedback control circuits to a suitable readout device, such as a galvanometer.  Each of the bridge circuits includes a filament exposed to the gas being measured.  A detector filament coated with a catalyst is posi-tioned in the detector bridge, and a reference filament without a catalyst is positioned in the reference bridge.  Initially, the bridge circuits are calibrated for operation of the exposed filaments at a preselected resistance and temperature.  In the presence of a gas containing combustibles, the catalyst on the detector filament promotes combustion of the gas thereby incres-ing the temperature and resistance of the detector filament to unbalance the detector bridge and vary the magnitude of the out-put signal to the feedback control circuit.  An operational amplifier of the control circuit is thus actuated at a reduced operating level to switch a transistor, connected to the power source and the input to the detector bridge, from a conductive state to a nonconductive state to thereby adjust the voltage level applied to the detector bridge. The bridge is returned to a balanced condition, and the detector filament is returned to its initial temperature.  The variation in the voltage supplied to the detector bridge is proportional to the concen-tration of combustibles present in the gas.  The readout of the galvanometer provides a quantitative measurement of the com-bustibles in the gas.  Adjusting the voltage applied to the detector bridge maintains the detector filament at a constant temperature to increase the operating life of the detector filament and reduce evaporation of the catalyst on the filament.

Abstract: ABSTRACT OF THE DISCLOSURE         This method of making 5,6-dihydro-2-methyl-N-phenyl-1,4-oxathiin-3-carboxamide is based on the use of an oxathiolane, namely, 2-methyl-N-phenyl-1,3-oxathiolane-2-acetamide, which may be formed by condensing 2-mercap-toethanol wlth acetoacetanilide under acidic conditions in a solvent medium (aromatic hydrocarbon, chlorinated hydrocarbon or alkyl ester of an aliphatic acid).  The said oxathiolane, with or without purification, is reacted with hydrogen peroxide in water or in a water-organic solvent mixture under basic conditions in the presence of a catalytic amount of a metal compound such as sodium tungstate to form 2-methyl-N-phenyl-1,3-oxathiolane-2-acetamide 3-oxide.  The said loxathiolane oxide, while dissolved in a chlorinated hydrocarbon or an alkyl ester of an aliphatic carboxylic acid, or while suspended in an aromatic hydrocarbon, is subjected to a ring expansion reaction by heating under acidic conditions in the presence of a catalytic quantity of a quaternary ammonium salt to form 5,6-dihydro-2-methyl-N-phenyl-1,4-oxathiin-3-carboxa-mide with evolutlon of water.  The product is a known bactericide and fungicide.
