Methods and systems for on-site, continuous generation of peracid chemistry, namely peroxycarboxylic acids and peroxycarboxylic acid forming compositions, are disclosed. In particular, an adjustable biocide formulator or generator system is designed for on-site generation of peroxycarboxylic acids and peroxycarboxylic acid forming compositions from sugar esters. Methods of using the in situ generated peroxycarboxylic acids and peroxycarboxylic acid forming compositions are also disclosed.

A method for treating open cut edges of a packaging sleeve, blank or web material of a packaging material rolled up into a roll, in particular a composite cardboard/plastics material, by applying or introducing a disinfectant-containing treatment agent to or into the outer region of the cut edges. To provide a particularly resource-efficient composite packaging and a production method required for this purpose, it is proposed that at least some of the treatment agent is not applied directly to the cut edges, but that a load carrier is loaded, which load carrier absorbs the treatment agent so that an actively sterilising atmosphere which is created then acts on the open cut edges of the packaging sleeve, blank or web material and performs the desired sterilisation. The invention also relates to a packaging material, to a combipack produced therefrom and to a container for receiving the packaging material.

Methods and systems for temperature-controlled, on-site generation of peracids, namely peroxycarboxylic acids and peroxycarboxylic acid forming compositions are disclosed. In particular, methods for using an adjustable biocide formulator or generator system overcome the limitations of temperature on the kinetics of the peracid generation and/or peracid decomposition inside an adjustable biocide formulator or generator system. The methods include the controlling of the temperature of at least one raw starting material, namely water, to improve upon methods of on-site generation of peracids. The methods allow for the generation of user-selected chemistry without regard to the ambient temperatures of the raw starting materials and/or the biocide formulator or generator system.

An apparatus for removing excess of a sterilization agent from a web of carton-based packaging material is presented. The web comprises a number of consecutively arranged sections arranged to be formed into packages, wherein each section of the web comprises an opening device attached thereto, wherein at least a subset of the sections comprises a positioning element. The apparatus comprises a positioning element reader arranged to determine a position of the positioning element comprised in or on the web, a control unit configured to estimate a position of the opening device based on the position of the positioning element, and an air pulse device arranged to provide an air pulse, wherein the control unit is further configured to adjust the air pulse device based on the position of the opening device, and the air pulse is provided onto an opening device area of the web such that sterilization agent is removed from the opening device.

A method and system for managing water in a food preparation sink is provided. The system includes a sanitizer comprising a chemistry optimized for a food preparation sink water load, a delivery system configured to transport and deliver the sanitizer to the food preparation sink; and a verification element that is configured to be added to the water load in the food preparation sink and indicate when the water in the food preparation sink is not promoting growth or spread of bacteria.

A gravity flow liquid disinfectant dispensing reservoir comprised of a tapered base and a neck portion that extends centrally from the reservoir. An aperture located on the bottom of the reservoir facilitates the dispensing of liquid (i.e., disinfectant) from the reservoir into a holding tank. In another embodiment, a closed system for dispensing a liquid disinfectant into a tank containing liquid (effluent) and controlled via vacuum. The gravity flow device introduces disinfectant to the tank as the water level rises, giving the ultimate amount of contact time for treatment of effluent. Utilizing gravity and vacuum controlled dispensing of disinfectant dispenses disinfectant continuously and automatically in real time and provides for maximum contact time for minimal pathogen survival.

The present invention is a method for removing a biofilm containing a metal and formed in a water system, wherein the biofilm is brought into contact with (a) a compound having a hydroxyl radical generation ability and (b) a reducing agent.

A portable, sterilizable light source unit for being coupled to an instrument is provided. The unit includes a sealed housing having an anodized coating and a port for receiving an end tip of a light guide of a separate instrument, a light source mounted within the sealed housing for directing light through the port, a battery mounted within the housing for powering the light source, a switch assembly mounted on the housing for controlling light output of the light source, and an O-ring in a compressed condition between the switch assembly and the housing providing a fluid-tight seal therebetween that prevents liquid intrusion into the housing during an immersion sterilization process.

A system is (10) for determining a flight rest scenario for an aircraft crew (12) comprising at least two pilots able to fly the aircraft (12) during a flight. The system (10) comprises a display device (16) comprising a screen (20), a module (32) for acquiring flight context and constraints inputs, and a module (34) for determining at least one crew rest scenario for the flight from the acquired inputs. The determination module (34) is able to determine the rest scenario from at least one simulation by a biomathematical fatigue model having at least one of the acquired inputs as variables. The system also includes a display management module (36) configured to display the determined rest scenario on the screen (20) of the display device (16).

A cleaning-disinfecting system may be utilized for one or both of cleaning and/or disinfecting medical devices. The cleaning-disinfecting system may be a portable battery-powered medical device washer-disinfector. The systems, devices, or methods may be specifically designed for use at home or other contexts and can wash and disinfect single or multiple medical devices simultaneously. The cleaning-disinfecting system may automatically reprocess medical devices placed within the cleaning-disinfecting system. The cleaning-disinfecting system may store medical devices after reprocessing without exposing the medical devices to potential contamination from the environment.
