Abstract: A method of applying a two-part dental sealant is described comprising providing a syringe device (1) comprising a cartridge (10) including first and second chamber. The first chamber contains a first part of a dental sealant comprising a (meth)acrylate resin and an oxidizing curing agent. The second chamber contains a second part of a dental sealant comprising a (meth)acrylate resin and a reducing curing agent that reacts with the oxidizing curing agent of the first chamber. The first and/or second part of the dental sealant further comprise a single component or multiple components that neutralize acid and promote remineralization. The syringe device comprises a dispensing nozzle (17) comprising a static mixer and an outlet at one end of the cartridge and a plunger (20) at the opposing end of the cartridge. Also described is a kit for storing and applying the dental sealant is described.

Abstract: A method of operating a network is beneficially conducted on a municipality or neighborhood level. The method in disclosed embodiments comprises installing a digital communications network within a limited selected geographical region. The network is formed from a high speed backbone and a plurality of nodes branching outward from the high speed backbone. A plurality of communicating stations are connected to the network and users at each communicating station subscribe to communicate over the network. Due to the unique scope of the network, the users are related primarily by virtue of their residence in a common geographical region. The network may be installed within a public utility right of way and may be used to monitor utility usage and to bill utility users. The network is thus independent of public telephone infrastructure. The network is preferably partitioned and communications are direct from station to station without broadcasting.

Abstract: Apparatus for maneuvering a physically impaired individual including a base member, a platform rotatably mounted relative to the base member for supporting the individual, a stabilizer projecting upwardly from the platform to be manually grasped by the individual, and a lock arrangement for selectively locking the platform and the base member against relative rotatable movement.
