Abstract: The present invention is directed to a door handle sanitizing cassette that is installed within an internal cavity formed within a door. Prior to the installation, the cassette is fitted with all required door hardware and the equipment necessary to spray the door handles with a sanitizing liquid each time the door is opened or at preset intervals. The invention is designed to provide an inexpensive and easily installed system in public buildings to substantially reduce the spread of infectious disease by eliminating contaminated surfaces on the door handles.

Abstract: A method of sterilizing containers by using a peracetic acid-type sterilizing composition solution, wherein the sterilizing composition solution containing peracetic acid, hydrogen peroxide, acetic acid and catalase as prepared in a circulating tank (1) is heated through a heating unit (3), fed to a sterilizing unit (4), and is recovered in the circulating tank (1) after it is used for the sterilization, wherein the catalase is added to the sterilizing composition solution in a circulating passage of after it was used for the sterilization but before it is fed to the heating unit. This makes it possible to suppress the catalase from losing its activity, to maintain the sterilizing power of the sterilizing composition solution, and to use the sterilizing composition solution in a circulating manner without cooling it saving, therefore, the heat energy providing advantage in economy.

Abstract: A lean MEG stream having a first pH level is contacted with a CO2-rich gas stream to yield a lean MEG product having a second different and lower pH level preferably in a range of 6.5 to 7.0. The system and method can be readily incorporated into a slipstream MEG recovery package, with a source of the lean MEG stream being a MEG regeneration section of the package. The CO2-rich gas could be a vented CO2 stream from the MEG reclamation section of the package. Unlike hydrochloric and acetic acid overdosing, CO2 overdosing of the lean MEG stream does not lead to rapid acidification of the lean MEG product to be stored or injected.

Abstract: In one example, we describe a method and system for toothbrush sterilization and/or storage with better quality in terms of hygiene and convenience, where the brush head and the shaft that enter the user's mouth are never contacted by the chamber. Also, below the brush head and shaft, there is no chamber. If any drops of water were to fall off the brush head, they would fall all the way through the chamber and reside on the counter on which the chamber rests, which can be removed or cleaned easily later. In one example, we use a UV-C lamp as our sterilization technique. This selection has many advantages over the other sterilizations techniques. In one example, we use a single lamp, but that lamp is in a ring configuration (otherwise known as annular, torus, or donut), with good coverage of the toothbrush, from all angles.

Abstract: An applicator assembly may include a body having a proximal end portion and a distal end portion, an actuator operatively coupled to the body, a container disposed within the body, an application member attached to the distal end portion, and a valve disposed between the container and the application member. Actuation of the actuator opens the valve and places the interior of the container in fluid communication with the application member by way of a compressive force applied to the body. A method of applying a solution to a surface may include actuating the actuator, wherein actuation of the actuator applies a compressive force to the body that opens the valve and places the interior of the container in fluid communication with the application member, and contacting the application member to the surface, thereby applying the solution to the surface.
