Publication number: 20070282704Abstract: A route service system and process for industrial applications includes, according to one example embodiment, a computer system having remote hand-held units, and begins with a preview route function which is, according to one example embodiment, completed one to three (3) days prior to service. The route service function summarizes items for a route service representative (RSR) that they may need to be aware of for servicing the route. A service route/supplied entity function leads the RSR through the steps needed to service each supplied entity on their route from start to finish. A check-in/approve route function gives visibility to management at the supply entity following a route's completion to assure proper business controls. According to one example embodiment, following the RSRs completion of a route, visibility of changes on the route are available to management and must be approved.Type: ApplicationFiled: June 6, 2007Publication date: December 6, 2007Applicant: G&K SERVICES, INCInventors: Rachel Elizabeth DeMaster, Michael John Pickett, Jeffrey Dean Donnelly

Publication number: 20050147635Abstract: cis-Jasmone has been discovered to be useful as a semiochemical that changes the behaviour of insects and/or the physiology of plants. It has direct signalling roles with plant-feeding aphids, in attraction of aphid predators and parasitoids, and may act as an airborne signal inducing production of volatile plant semiochemicals, including the monoterpene (E)-?-ocimene, that stimulate foraging by parasitoids. It is an extremely benign compound having, to human beings, a pleasant aroma and gives a long-lasting effect after removal of the stimulus.Type: ApplicationFiled: November 24, 2004Publication date: July 7, 2005Inventors: Alastair Hick, John Pickett, Lester Wadhams, Johnathan Napier
