摘要:
A lubricating oil composition for refrigerating machines contains a base oil and an additive in a form of a naphthalimide compound. A refrigerant used in a refrigerating machine in which the composition is used is unsaturated hydrofluorocarbon (unsaturated HFC) having a GWP of 1000 or less. When the present lubricating oil composition for refrigerating machines is used in refrigerating equipment such as an open-type automobile air-conditioner, an electric automobile air-conditioner, a gas heat pump, other air-conditioning equipment, a refrigerating machine, a vending machine, a showcase, a water-heating system and a refrigerating/heating system, it is possible to detect the leakage of a refrigerant with a long-lasting stability. Therefore, when an unsaturated fron refrigerant with a poor stability is used in the above-listed equipment, the present lubricating oil composition for refrigerating machines is significantly advantageous.
摘要:
A process for detecting oil or lubricant contamination in a manufactured product, the process comprising adding a fluorescent taggant to oils or lubricants contained in processing machinery for said product, conveying said product past an infrared detection apparatus, irradiating said product with infrared radiation from said detection apparatus as it passes the detection apparatus, and detecting infrared radiation emitted from said irradiated product.

摘要:
A copolymer is prepared by the polymerization of monomers that include an ultraviolet absorbing monomer, and a base-solubility-enhancing monomer. The copolymer is useful for forming a topcoat layer for electron beam and extreme ultraviolet lithographies. Also described are a layered article including the topcoat layer, and an associated method of forming an electronic device.
摘要:
A process for detecting oil or lubricant contamination in a manufactured product (C), preferably a cigarette (C), the process comprising adding a fluorescent taggant to oils or lubricants contained in processing machinery for said product (C), conveying (131) said product (C) past an infrared detection apparatus (140), irradiating said product (C) with infrared radiation from said detection apparatus (140) as it passes the detection apparatus (140), and detecting infrared radiation emitted from said irradiated product (C). The taggant can be in the form of a composition containing a Stokes-shifting taggant, which absorbs radiation at a first wavelength and emits radiation at a second wavelength, different from said first wavelength, dissolved or dispersed in an oil or lubricant.

摘要:
A system for detecting oil contaminated product and foreign matter within a product stream is provided. The system includes a first conveying means for delivering a product stream; a first detection apparatus for detecting oil contaminated product, the first detection apparatus positioned proximate the product stream, the first detection apparatus including a high intensity infrared light source directed at the product stream; and a high speed NIR spectrometer sensor tuned to detect a reflected signal from a taggant disposed in the oil of the oil contaminated product; a second detection apparatus for detecting foreign matter within a product stream, the second detection apparatus positioned proximate the product stream, the second detection apparatus including a light source for illuminating the product stream and a detector for detecting light reflected from the product stream; and a controller for determining whether the product stream contains oil contaminated product or foreign matter by monitoring signals obtained from the first detection apparatus and the second detection apparatus.
摘要:
A process for detecting oil or lubricant contamination in the production of an article by adding a Stokes-shifting taggant to an oil or lubricant of a machine utilized to produce the article or a component thereof, irradiating the articles produced with a first wavelength of radiation, and monitoring the articles for emission of radiation at a second wavelength. The taggant can be in the form of a composition containing a Stokes-shifting taggant, which absorbs radiation at a first wavelength and emits radiation at a second wavelength, different from said first wavelength, dissolved or dispersed in an oil or lubricant.
