    摘要: A fuel delivery system for automotive engine and like applications comprises a canister for positioning within a fuel tank so as to be surrounded by fuel in the tank. An electric-motor fuel pump has an inlet and an outlet for feeding fuel under pressure from the tank to the engine. Excess fuel is returned from the engine to the canister. A fuel level sensor includes a pressure sensor positioned at a lower portion of the canister and responsive to head pressure within the canister and within the surrounding tank for providing an electrical signal as a function of a difference between such pressures. An indicator is responsive to such electrical signal for displaying tank fuel level to an operator.

    摘要: Pliers for forming and removing bumps for the dental appliance without heating are disclosed. The eraser pliers for erasing a bump on an appliance include a first elongated member having a first jaw portion at one end and a handle portion at the other end, the jaw portion having flat surface mounted at a distal end of the first jaw portion; and a second elongated member joined to the first elongated member, the second elongated member having a second jaw portion at one end and a second handle portion at the other end, the second jaw portion having a second flat surface mounted at a distal end of the second jaw portion, the first and second flat surfaces adapted to engage and flatten the bump. The pliers for making the bumps include a first elongated member having a first jaw portion at one end and a handle portion at the other end, the jaw portion having a projection mounted at a distal end of the first jaw portion; and a second elongated member joined to the first elongated member, the second elongated member having a second jaw portion at one end and a second handle portion at the other end, the second jaw portion adapted to receive the projection to create the bump in the dental appliance without heating.
