sacrificing the resolution, parallel integrators are provided so that a second integrator can in- tegrate electrical signals from a second scintilla- tion event during the time that a first integrator is processing the signals from a first scintillation e- vent. Common storage buffers are connected to the integrators to hold the integrated signals for further processing.

A bottle cap of the pushbutton type having a jacket threaded to fit to the bottle top, and a round pushboard intertitted and pivotally mounted in the jacket with protrusions on the pushboard to control openings of an effluent pipe and an air intake pipe mounted in a check board portion of the jacket, with an effluent port and an air intake path in the pushboard for fluid connection to those respective pipes. The ports on the bottom of the jacket leading to the pipes therein are spaced from each other by use of a shield over the bottom port of the air intake pipe allowing pouring of a liquid from the bottle, using a pushbutton type cap, through the ef- fluent pipe, without interference with the air in- take system.

METHOD AND APPARATUS FOR MONITORING ROTARY DRUMS

DURING THERMAL PROCESSING

Gernot Jager, Hubert Spitz, Herbert Specht, Cologne, Federal Republic Of Germany as- signed to Klockner-Humboldt-Deutz AG

A method and apparatus for monitoring the operation of a rotary drum such as a rotary kiln while engaged in thermal processing of fine grained materials such as cement which involves measuring the temperature distribution existing instantaneously during such processing by means of one or more sensors which are not in contact with the drum and comparing the dist- ribution with other parameters related to the thermal processing. Such other parameters may

A plant for the treatment of waste water, such as municipal sewage and industrial wastes con- taining organic matter which must be decom- posed, comprises a mechanical clarifier for the removal of non-degradable and coarse con- taminants, an activation vessel for a first diges- tion stage operating with an oxygen content close to 0 mg/1 with facultative anaerobic opera- tion, an intermediate clarifier, an aeration stage formed by a trickling filter for oxidative decom- position, an afterclarifier and an arrangement for removal and preferably the treatment of sur- plus sludge. An unaerated mixture (facultative anaerobic) basin is provided upstream of the af- terclarifier in which water from the trickling fil- ter is contacted with surplus sludge from the activation basin.

4487784

A flue gas desulfurization process capable of producing a high purity gypsum and also making equipment employed as minimum as possible is provided, which process comprises the steps of cooling and dedusting flue gas con- taining SOx; contacting the cooled gas with a slurry containing limestone to remove SOx by absorption and also form CaSO3; controlling the pH of the resulting slurry and then blowing air therein to form gypsum; and separating gypsum from the resulting slurry. As a modifica- tion of the above process, the slurry of the above second absorption step is further fed to the above first cooling step where unreacted limestone and SOx are reacted to form CaSO3.
