  • Premises gateway and premises network interfaces for accessing subscriber premises equipment and communication networks using ring suppression
    Publication number: 20010010716
    Abstract: A premises gateway is provided with respect to a subscriber's premises and a plurality of different transmission media for connecting to network devices and host systems on a network. The premises gateway has interchangeable network interface cards and cards for communicating with different nodes on a subscriber's premises using different transmission media and protocols. The nodes are provided with premises network interfaces which operate in conjunction with the premises gateway to allow, for example, devices connected to the same telephone line, but to different telephone wall jacks, to be addressed separately. The premises gateway can communicate analog signals and broadband signals on a twisted pair to the same node. The premises gateway can also be provided at a central office to operate as an Internet protocol gateway.

  • Ratcheting wrench
    Patent number: 5996445
    Abstract: A ratcheting open-ended wrench has a movable jaw pivotally attached to a fixed jaw. The jaws define an opening capable of receiving the hexagonal head of a fastener such as a nut, bolt, hose fitting or pipe fitting. The fastener may be turned by moving the handle of the wrench back and forth without disengaging the fastener from the opening. A stop prevents the movable jaw from moving in a way which would place excessive stresses on the movable jaw. An arc shaped bearing surface on the movable jaw is received in a mating bearing surface on the fixed jaw. The combination of the stop and the mating bearing surfaces greatly reduces shear forces on the pivot. The point about which the movable jaw pivots is located forwardly relative to the opening. A wrench according to the invention can be both strong and compact. The wrench is reliable simple to manufacture and may be made with only three or four parts.
