between its sides. A detector is connected to the output side of the valve for measuring the peak pressure thereof over several operating cycles of the user and a controller is connected to the detector for operating when the peak pressure detected over several operating cycles exceeds a predetermined threshold.
PROCESS FOR TREATMENT OF CLARIFICATION SLUDGE 4967664 Carl H Gregor, Gr Federal Republic Of Germana assigned to Peroxid-Chemie GmbH The present invention is in a process for the treatment of clarification sludge, wherein a sludge is treated with a per acid containing up to 3 carbon atoms and subsequently allowed to digest in a septic plant.
4967238 CLEANING PERFORMANCE MONITOR Jan Bares, Richard H Tuhro assigned to Xerox Corporation An arrangement for detecting toner or debris deposits on an imaging surface is arranged downstream from the cleaning station. The imaging surface is illuminated with a light source, a light intensity detecting sensor arrangement is provided to view the illuminated surface and produce a signal representative of detected light intensity, and a response signal is produced indicative of the condition of the surface.
METHOD AND APPARATUS FOR AUTOMATICALLY CLEANING LIQUID SUPPLY ROLLERS OF OFFSET PRESS Takashi Iijima, Yokosuka, Japan assigned to Kabushiki Kaisha Tokyo Kikai Seisakusho Method and apparatus capable of automatically cleaning a dampening water supply passage to a plate cylinder in an offset press, as well as an ink supply passage to the late cylinder. The apparatus comprises an operation instruction means producing operation signals in a sequence to driving portions of various means which include ink supply-stopping means, means for supplying a cleaning solvent, cleaning waste recovering means, means for bringing ink supply rollers out of contact with the plate cylinder, means for bringing dampening water supply rollers out of contact with the plate cylinder, and main control means, a start instruction means that starts the operation instruction means, and a manual instruction means. This manual instruction means permits the operator to select either cleaning of only the ink supply passage or cleaning of all the ink supply passage and the dampening water supply passage.
4967553 SYSTEM FOR MONITORING A HYDRAULIC ACCUMULATOR Jean-Claude S Barthomeuf, Anse, France assigned to Eimco-Secoma Societe Anonyme A high-pressure source of hydraulic fluid and a sump are connected to a cyclically operating user of hydraulic fluid having a hydraulic accumulator by a high-pressure feed line having one end connected to the source and an opposite end connected to the accumulator and user. A pressure-limiting valve has an input side connected to the high-pressure line between the ends thereof and an opposite output side connected to the sump. This valve opens only when pressure in the line exceeds a preset maximum to allow flow
4968407 SLUDGE DEWATERING AND DESTRUCTION WITHIN A DELAYED COKING PROCESS Michael McGrath, Rino Godino assigned to Foster Wheeler USA Corporation Wet refinery sludges are disposed of by feeding them into a delayed coking process. The sludge is fed to the blowdown drum of the delayed coking process and mixed with oil condensed from the coke drum overhead, and the resulting sludge-oil mixture is fed to the coke drum where it is converted into coke. In order to remove the water from the sludge, a portion of the sludge-oil mix-
