  • High force and high stress destructuring of cellulosic biomass
    Patent number: 10227623
    Abstract: A process for mechanical destructuring of cellulosic biomass was developed that makes use of a short application of high compression, impact, and shearing forces. The biomass may be destructured using a specific energy input that is less than 40% of the total combustible energy of the biomass. The destructured biomass, with or without saccharification and/or in-feed glycosyl hydrolase enzymes, may be used in feed applications.

  • Telephone network having dual gateway interconnection architecture for handling emergency services
    Patent number: 6252943
    Abstract: A telephone network includes one or more end office switches not directly connected by a trunk line to a 911-type emergency tandem switch to handle emergency telephone calls. For those end office switches not so connected, a received emergency “9-1-1”-type telephone call is routed to a gateway switch having a trunk line connected to the emergency tandem. In the network, a first gateway switch connected to the emergency tandem switch provides the primary link, while a second gateway switch connected to the emergency tandem switch provides the secondary link. Routing information resident in end office switches is sent to the switch network to facilitate proper handling of an emergency call. The disclosed telephone network allows for less than full connectivity between gateway switches and an emergency tandem switch, while still providing a measure of redundancy to help ensure that an emergency call is completed.
