Publication number: 20180023217Abstract: Fibers for generating antimicrobial activity are described. The fibers comprise an enzyme that is able to convert a substrate to release hydrogen peroxide, and an unrefined natural substance that includes a substrate for the enzyme, wherein the enzyme is additional to any enzyme activity able to convert the substrate to release hydrogen peroxide that may be present in the unrefined natural substance. In the presence of sufficient free water, the enzyme converts the substrate to release hydrogen peroxide, which is effective against a wide range of microbes. Wound dressings and compositions comprising the fibers are also described, as is use of the fibers, wound dressings and compositions, particularly for wound healing.Type: ApplicationFiled: February 3, 2016Publication date: January 25, 2018Applicant: MATOKE HOLDINGS LIMITEDInventors: Thomas PATTON, James BRENNAN, Ian STAPLES, Iain ELDER, Annette CALLAGHAN, Matthew DRYDEN, John Reginald BARRETT, David KERSHAW, Rami SALIB

Publication number: 20170266240Abstract: Compositions for prevention and treatment of microbial infectious, such as microbial infections that comprise a biofilm, or a microbe that is capable of forming a biofilm are described. The compositions comprise an enzyme that is able to convert a substrate to release hydrogen peroxide and a substance that includes a substrate for the enzyme. The enzyme is additional to any enzyme activity able to convert the substrate to release hydrogen peroxide that may be present in the substance.

Patent number: 9352503Abstract: According to embodiments, there is provided a method (300) of controlling a first melt accumulator (121). The first melt accumulator (121) is part of an injection unit (100), the injection unit (100) including an extruder (102) for preparing molding material and a second melt accumulator (123). The first melt accumulator (121) and the second melt accumulator (123) are configured to sequentially receive molding material from the extruder (102). The extruder (102) is being operable to produce molding material in at least near continuous manner, both the first melt accumulator (121) and the second melt accumulator (123) being associated with a respective shot size set-point. The method comprises detecting (310) an indication of an out-of-boundary condition associated with operation the first melt accumulator (121); responsive to said detecting (310), controlling (320) the first melt accumulator (121) to continue accepting molding material beyond its respective shot size set-point.Type: GrantFiled: January 19, 2011Date of Patent: May 31, 2016Assignee: HUSKY INJECTION MOLDING SYSTEMS LTD.Inventors: Michael David Kershaw, Kevin Wing Hang Leung, Mark Aaron McDonald

Publication number: 20120179288Abstract: A method (300) is provided for controlling an injection unit (100) having a first sub-assembly and a second sub-assembly, first and second sub-assemblies being functionally identical units. The method (300) includes the steps of appreciating an operational parameter for each of the first and second sub-assemblies, appreciating a target set point (146) associated with operating each of the first and second sub-assemblies, and when the operational parameter for at least one of the first and second sub-assemblies differs from the target set point (146), adjusting the operation of the at least one sub-assembly towards the target set point (146) by a control action. The adaptive control regulator (148) is operable to modify the control law of one of the first and second sub-assemblies so that the first and second sub-assemblies have substantially equal performance.Type: ApplicationFiled: June 21, 2010Publication date: July 12, 2012Applicant: Husky Injection Molding Systems Ltd.Inventors: Kevin Wing Hang Leung, Michael David Kershaw

Publication number: 20090043621Abstract: The invention is an application for teams of information workers, their managers, and human resources professionals to evaluate and raise performance based on communication metrics and norms of behavior within a team. A model and management Web pages enable users to collectively set norms of behavior, communicate, make decisions, set roles and goals, receive evaluations according to their norms, and in other ways conduct interpersonal relations in a business context. Modules acquiring data from email and document management systems, groupware, directories, and other information sources are included. Said information is joined with the invention's internally generated data. An expert system generates observations and advice permitting the team to more appropriately deploy information, adhere more closely to its norms, and lessen stress caused by interpersonal friction. Management is provided a means of assessing teams, setting policies, and defining parametric ranges for norms.Type: ApplicationFiled: August 9, 2007Publication date: February 12, 2009Inventor: David Kershaw
