    摘要: A liquid waste processing apparatus having a liquid waste processing vessel for separating and recovering floating sludges. The liquid waste processing vessel includes an inlet disposed on its one side wall for receiving liquid wastes from above and turning them toward an exit disposed on the other side wall of the vessel, slanted downwardly toward the one side wall, and an inclined plate disposed above the exit for forming a shallow portion below the liquid surface and extended along the inclination of the opposite side wall toward the one side wall to define a narrow flow channel between the plate and the opposite side wall which is in communication from the bottom to the exit. The cross-sectional area of the narrow flow channel is made smaller than that of the channel opening. Floating sludges and precipitating sludges contained in liquid wastes from a coating booth, etc. can be separated and recovered completely and easily.

    摘要: A method of operating an air-supplied type coating booth in which conditioned air supplied from an air supply blower is enforced downwardly to the inside of a tunnel-shaped coating booth and the air in the coating booth is drawn together with paint mists and the likes down to the beneath of a booth floor by way of an air exhaust blower comprises the steps of detecting the flow velocity of air streams flowing into or out of inlet and the exit of the coating booth, applying primary and secondary averaging processings for signals for averaging variations caused by external disturbances fluctuating at relatively shorter and longer periods of time, judging the thus averaged direction and the flow velocity of the air streams at the inlet and the exit, variably controlling the flow rate of exhaust from the exhaust blower in accordance with the direction and the flow velocity. The exhaust blower means are divided into a plurality of blowers and the minute variations in the direction and the flow velocity are controlled excessively by the blowers situated at the inlet and the exit of the coating booth, while remaining exhaust blowers are operated at predetermined flow rate.

    摘要: A method of operating an air-supplied type coating booth adapted to enforce conditioned air by an air supply blower through a filter downwardly to the inside of a tunnel-shaped coating booth at a predetermined flow velocity and then drawn to discharge together with coating mists, etc. to the beneath of the floor comprises the step of detecting the flow velocity of conditioned air flowing through the filter to the inside of continuously, applying primary and secondary averaging processings for the detected signals containing variations fluctuating at relatively shorter and longer periods respectively, comparing the value obtained from the signals applied with the secondary averaging processing with a predetermined flow velocity value and variably controlling the flow rate of the air supplied from the air supply blower depending on the deviation and thereby maintaining the flow velocity of the conditioned air flowing to the inside of the coating booth always constant. Reduction of the flow velocity supplied to the inside of the air-supplied type coating booth due to the filter clogging can be compensated exactly with no effects of external disturbances.

    摘要: A cyclic ester (e.g., a lactone such as ε-caprolactone) is ring-opening addition polymerized with a dihydroxycarboxylic acid in the presence of a basic compound (e.g., an amine). In a polyester polyol obtained by such a process, at least part of a carboxyl group of the polyester polyol forms a carboxylate with the basic compound, and the content of the dihydroxycarboxylic acid in a free form can be remarkably reduced (for example, reduced to not more than 5% by weight relative to the total polyester polyol). According to the present invention, a polyester polyol having a reduced content of a free or unreacted dihydroxycarboxylic acid is provided even in the case of using a dihydroxycarboxylic acid (e.g., a dimethylolalkanoic acid such as dimethylolpropionic acid) as an initiator.

    摘要: The present invention relates to a polyglycerol significantly reduced in content of a polyglycerol having a cyclic structure formed by removal of a water molecule from a polyglycerol molecule, and to a fatty acid ester of a polyglycerol having excellent surface activity. 2 mole or more of glycidol and a catalyst are successively added to 1 mole of glycerol for a reaction to obtain a polyglycerol, in which a ratio of [total polyglycerol (1)] to [total polyglycerol (2) having a cyclic structure] is [70% or more]/[30% or less] (the total of both is 100% by weight) in terms of an intensity ratio determined by liquid chromatography/mass spectrometry; and an average polymerization degree “n” is 2 or more. A reaction of a polyglycerol with a fatty acid provides the corresponding a fatty acid ester of the polyglycerol.

    摘要: An ejector is configured to generate a high negative pressure capable of sucking and conveying fine metal pieces or chips, such as machinings or cuttings, for example, when using the ejector as a driving source for a fluid conveyor. The ejector includes a convergent-divergent nozzle having a throat formed between a suction port and a discharge port. Jet blowing holes are formed in the convergent-divergent nozzle to direct a jet stream from upstream of the throat to downstream of the throat, thereby forming a negative pressure. Pressure control holes open to the downstream of the jet blowing holes and are configured to communicate with a pressure space at a pressure level higher than a negative pressure formed by the jet stream and lower than a static pressure of the jet stream and the inside of the convergent-divergent nozzle.
