Abstract: Disclosed is an aqueous developing solution containing a quaternary ammonium hydroxide developing agent, and as an additive an effective amount of a select compound which is either 1,3,5-trihydroxy benzene, 4-methylesculetin or a novolak-type resin. The aqueous developing solution is particularly useful in developing an imagewise-exposed layer of a positive-working photoresist composition containing a novolak-type resin and a photosensitive agent. In such application, it has been found that the developing solution more effectively removes the exposed portions of the photoresist composition without leaving a residue of exposed photoresist composition at the interface of the edges of the unexposed portions of the photoresist composition and the oxidized silicon substrate.

Abstract: A process for producing cyanuric acid which comprises feeding a urea hydrohalide compound to a pyrolysis zone.The urea hydrohalide compound is pyrolyzed to produce a solid reaction mixture of cyanuric acid and an ammonium halide. The solid reaction mixture is vaporized to remove the ammonium halide to form a gaseous mixture containing ammonia and hydrogen halide which is simultaneously removed from the pyrolysis zone. The cyanuric acid recovered is substantially free of ammonium halide.The novel process produces high purity cyanuric acid in the absence of liquid effluents while readily recovering the ammonia and hydrogen halide values.

Abstract: A boiler blowdown monitoring system wherein the conductivity of the water in the boiler blowdown line is monitored to determine if it exceeds either a preset maximum or minimum level. The system includes a blowdown sensor, a blowdown valve, a blowdown controller and an interrogation means. The water conductivity is sensed by the sensor located on the blowdown line and transmitted to the interrogation means (e.g. microprocessor) through the boiler blowdown controller. If the sensor senses a water conductivity level above a preselected maximum conductivity level or below a preselected minimum conductivity level after a predetermined time period has passed since the boiler blowdown valve was opened, then an alarm signal is sent to the boiler operator.
