  • Patent number: 9820445
    Abstract: The present invention relates to cutting tools, in particular, to control systems for cutters such as vegetation cutters, especially hedge cutters or trimmers (10). Hedge cutters (10) frequently suffer in use from a problem of blocked cutting blades when they encounter a twig or branch whose size or density exceeds the capacity of the blades. We describe a vegetation cutting apparatus (10) having a plurality of cutting blades (11,12), at least one of which blades (11,12) is drivable by an electric motor. At least one driven blade (11,12) is movable between two predefined points of maximum travel. The apparatus (10) includes a control mechanism which causes a change of direction in the movement of the at least one movable blade at a point intermediate the points of maximum travel in response to an event sensed by the control mechanism.

  • Patent number: 9765408
    Abstract: A process for stable fermentation of CO-containing substrates and improved ethanol productivity includes providing medium components in amounts needed by microorganisms in the fermentation. The process includes determining a potassium concentration in the fermentation medium and providing a first medium and a second medium to the fermentation, the first medium provided at a rate effective for maintaining the potassium in the fermentation medium in a range of about 20 to about 200 mg/L until reaching a target cell density.

  • Publication number: 20160366920
    Abstract: A system and method for producing a packaged food article or beverage may include processing a first food source including a spoilage microorganism along a first processing path, which may limit temperature of the first food source to be below a temperature level that causes the spoilage microorganism to be inactivated. A second food source may be processed along a second processing path, which may heat the second food source to be in a predetermined temperature range that causes spoilage microorganisms in the second food source to be substantially inactivated when in the predetermined temperature range for a predetermined period of time. A package may be filled with the first and the second food sources. The second food source, when mixed with the first food source, may be in the predetermined temperature range for the predetermined period of time in the package to inactivate the spoilage microorganism.

  • Publication number: 20150258476
    Abstract: A method of repeatedly indicating to a user of an appliance that a water filter unit operably connected to the appliance has passed its useful life and a filter unit configure for use in connection with the method where the filter unit includes a fluid flow impeding system within a housing of the filter unit; engaging the filter unit with the appliance; measuring the volume of water treated by the filter unit; activating a fluid flow impeding system contained within the housing of the filter unit; and repeatedly indicating to a user that the maximum volume of water the filter unit has been designed to treat has been surpassed and the filter unit should be replaced by repeatedly delivering a normal flow rate of water from the dispenser of the appliance and thereafter slowing the flow of water from the dispenser of the appliance.
