20080302125 | TEMPERATURE-CONTROLLED COMPARTMENT - The invention concerns a storage unit that is adapted to be located in a refrigeration appliance. The storage unit includes a holding compartment for holding articles the temperature of which is to be controlled. The holding compartment is adapted to be placed in air flow communication with a source of cold air whereby the cold air may be delivered to the holding compartment. An air-flow passageway for recirculating air discharged from the holding compartment back to the holding compartment is provided along with a mixing area where the cold air and the recirculated air may be mixed in selected quantities. A user interface providing for the selection of a temperature-control procedure from a group of available temperature-control procedures for application to the interior of the holding compartment is included. The storage unit can include a controller for controlling the implementation of the temperature-control procedure selected by the user. | 12-11-2008 |
20080302441 | STORAGE COMPARTMENT - A storage compartment comprises an external enclosure having an opening and a holding compartment that is capable of being inserted into and withdrawn from the interior of the external enclosure through the opening in the external enclosure. Stored articles are contained within the holding compartment. The external enclosure and the holding compartment have coacting surfaces, and a seal is interposed between those coacting surfaces for sealing off the interior of the holding compartment to the entry of gases when the holding compartment is inserted into the external enclosure and the coacting surfaces of the external enclosure and the holding compartment are brought together in a sealing relationship with the seal. Complementary surfaces at the holding compartment and at the exterior of the external enclosure are in engagement with one another and provide surfaces along which the holding compartment travels when it is inserted into and withdrawn from the interior of the external enclosure. | 12-11-2008 |
20090037019 | Vending machine dispensing system - A dispensing system for a vending machine includes a vend motor, a cradle, a load bar and a push arm. Upon selection of a particular product, the vend motor rotates the cradle, causing the product to emerge from the vending machine. The cradle is designed to accommodate a wide array of container sizes. The dispensing system incorporates a rotation sensor, a position sensor, and a lift arm. The sensors enable accurate rotation of the cradle through a plurality of vend angles depending upon the particular product being vended, while the lift arm cooperates with the push arm and load bar to refill the cradle after a series of product containers have been dispensed. In addition, the vend motor includes a soft start control that prevents instantaneous rotation of the output shaft so as to prolong an overall operational life of the motor. | 02-05-2009 |

20090123505 | Particulate Wood Preservative and Method for Producing Same - A wood preservative includes injectable particles comprising one or more sparingly soluble copper salts. The copper-based particles are sufficiently insoluble so as to not be easily removed by leaching but are sufficiently soluble to exhibit toxicity to primary organisms primarily responsible for the decay of the wood. Exemplary particles contain for example copper hydroxide, basic copper carbonate, copper carbonate, basic copper sulfates including particularly tribasic copper sulfate, basic copper nitrates, copper oxychlorides, copper borates, basic copper borates, and mixtures thereof. The particles typically have a size distribution in which at least 50% of particles have a diameter smaller than 0.25 μm, 0.2 μm, or 0.15 μm. At least about 20% and even more than 75% of the weight of the particles may be composed of the substantially crystalline copper salt. Wood or a wood product may be impregnated with copper-based particles of the invention. | 05-14-2009 |
20090143478 | Milled Submicron Organic Biocides With Narrow Particle Size Distribution, and Uses Thereof - A method of milling substantially insoluble solid organic biocides to form a micron or sub-micron product having a narrow particle size distribution is presented. The milling involves wet milling of the organic biocide with high density milling media having a diameter between 0.1 mm and 0.8 mm, preferably between 0.2 mm and 0.7 mm, and a density equal to or greater than 3.8 g/cc, preferably greater than 5.5 g/cc, in a ball mill using between about 40% and 80% loading of the mill volume with milling media, and having the organic biocide suspended in an aqueous milling liquid which comprises one or more surface active agents. The milling speed is preferably high, for example from about 1000 rpm to about 4000 rpm. The milled product can be used in foliar applications at a lower effective dosage than prior art formulations, can be used in improved antifouling paint formulations, and can be used in new applications such as the direct injection of solid organic biocide particulates in wood to act as a long lasting wood preservative. | 06-04-2009 |
