  • Patent number: 9676011
    Abstract: Equipment and method for a system implementing a multistep washing process, with a chemical container (110A-110D) for each chemical (111A-111D) and means for conveying one chemical at a time from the container through a feed channel (120) to a washing object (100) and from the washing object through a return channel (130) back to the container. First and second sensors (122, 132) monitor a first parameter set in the feed channel (120) and a second parameter set in the return channel (130), respectively. Both parameter sets include parameter(s) indicating the purity of the chemical. A control center (150) includes calculation means (153) arranged to determine the mutual uniformity of the first and second monitored parameter sets. Action time of the chemical is determined on the basis of the mutual uniformity of the first and the second monitored parameter sets.

  • Patent number: 9637607
    Abstract: A method of making a foam from a polymerizable resin includes the following steps. A thermally-activated initiator having a temperature below the initiation temperature is combined with an elevated-temperature solution having the polymerizable resin and carbon dioxide at a temperature above a promoted temperature to create a resulting mixture having a temperature above the promoted temperature. The resulting mixture is expanded by decreasing the pressure of the mixture to create a froth having a plurality of cells formed by carbon dioxide that expanded out of solution. The polymerizable resin within the froth is cured to create a foam.

  • Patent number: 9406212
    Abstract: An automated process for monitoring and controlling contamination activity in a production area comprises capturing image from the production area over a period of time, processing the image data with a computer to determine whether a contamination event has occurred in the production area, and activating a contamination control device in accordance with the processing of the image data. The contamination event can be a germ-releasing event from an individual in the production area, a pipe leaking fluid into the production area, etc. The automated monitoring and control may also determine whether an article of contamination control equipment (e.g., face mask, glove, etc) is properly positioned on the individual to prevent the contamination from entering the production area in a form that could contaminate product, equipment, or the production area itself.

  • Patent number: 9233524
    Abstract: An integrated process for making an inflatable laminated article comprises extruding a first film and a second film, followed by cooling the first film and the second film so that the films will not fuse to one another upon contact with each other. The films are then brought into contact with one another, and selected portions of one or both films are heated so that the films are heat sealed to one another in a selected area having a desired pattern. The unsealed area between the film provides inflatable chambers between the first film and the second film. An alternative process utilizes a film tubing in lay-flat configuration to produce a laminated inflatable article.

  • Patent number: 9189949
    Abstract: In an automated process for monitoring and controlling contamination in a production area, captured image data is processed to determine whether an individual is to wearing an article of contamination control equipment (e.g., gloves, face mask, etc) and whether the equipment is properly positioned on the individual. A determination that the contamination control equipment is not present or not properly positioned automatically activates a contamination control device such as contamination control means (e.g., shutting off power to machine) or an alarm or generates and sends a report of the contamination control protocol violation. An automated system for monitoring and controlling contamination includes a computer, an imaging sensor in communication with the computer, and a computer-readable program code disposed on the computer.

  • Patent number: 9143843
    Abstract: A machine vision process monitors and controls safe working practice in a production area by capturing and processing image data relative to personal protective equipment (PPE) worn by individuals, movement of various articles, and movement-related conformations of individuals and other objects in the production area. The data is analyzed to determine whether there is a violation of a predetermined minimum threshold image, movement, or conformation value for a predetermined threshold period of time. The determination of a safety violation triggers computer activation of a safety control device. The process is carried out using a system including an image data capturing device, a computer and computer-readable program code, and a safety control device.
