Abstract: Disclosed are nitrogen-containing heterocyclic compounds of relatively low aquatic toxicity and methods of using the heterocyclic compounds as corrosion inhibitors. The present method is used to inhibit corrosion of a metal surface in contact with an aqueous system using pyrazole derivatives, and provides enhanced protection against corrosion of metals in aqueous systems. The method comprises the use of corrosion inhibitors that are generally resistant to halogen attack and provide good corrosion resistance in the presence of oxidizing halogen-based biocides. Formulations comprising pyrazole derivatives are also disclosed.
Abstract: A system for releasing flavor is disclosed. The system comprises: a plurality of compartments adapted to receive a respective plurality of capsules, each capsule containing therein a flavor material; a dispenser system configured for dispensing into an environment a fluid obtained from at least one flavor material; and a controller configured for receiving data pertaining to a selection of at least two of the compartments and for signaling the dispenser system to dispense fluids obtained from flavor materials contained in capsules of the selected compartments.
Abstract: A sterilization system includes a sterilization chamber, a processor, and a sterilization module. The sterilization module includes a frame assembly, an extraction assembly, and a carriage assembly. The extraction assembly is configured to extract a sterilant fluid from a cartridge and transfer the sterilant fluid to the sterilization chamber. The carriage assembly includes a motor, a carriage body, and a translating flag. The carriage body is configured to receive the cartridge. The translating flag is configured to move from a first position to a second position relative to the carriage body in response to the carriage body receiving the cartridge. The sensor is configured to detect movement of the translating flag from the first position to the second position.
Abstract: The present invention provides a porous sustained-release body in which transparency of a porous carrier changes. The porous sustained-release body includes an inorganic monolithic porous body 1 including a skeleton body 2 of an inorganic compound and air gaps 3,4 having a three-dimensional continuous network structure formed in the skeleton body 2, and a sustained-release liquid absorbed into air gaps 2, 3, wherein the inorganic monolithic porous body 1 is opaque at an initial state, which is a state before absorption of the sustained-release liquid in which air exists in the air gaps, and refractive index of the sustained-release liquid and refractive index of the skeleton body are the same within an error range within which a portion in which the sustained-release liquid is absorbed into the air gaps changes to transparent or semitransparent.
Abstract: A curtain sanitizer device and method, such as for use in the healthcare industry, is disclosed that can sanitize at least a portion of the surface of a hung curtain, e.g. a privacy curtain, by directing UV-C light thereat to kill or inactivate harmful microorganisms thereon that can cause infectious disease, thereby reducing the risk of spreading infectious disease. In one example, at least a portion of opposite surfaces or sides of the hung curtain can be simultaneously sanitized. The curtain sanitizer device and method can allow the curtain to be cleaned in place, and can be easier to use and less costly and time consuming than other currently available methods and devices.
