Patent number: 8256645Abstract: A fluid dispenser is disclosed where a backoff distance is determined and implemented to prevent leakage while dispensing sequentially an accurate, precise amount of fluid substantially independent of the fluid remaining in a syringe-type dispenser. The fluid characteristics of the fluid, e.g. viscosity, surface tension, etc. affect the backoff distance that may be determined heuristically for fluid type, amount of fluid remaining in the syringe and amount to be dispensed. Once the fluid characteristics are known, the dispensing may be accomplished automatically with a processor loading new drive and backoff steps to a motor controller.Type: GrantFiled: September 28, 2009Date of Patent: September 4, 2012Assignee: Fishman CorporationInventor: W.

Patent number: 7607459Abstract: A nozzle attachment for a conventional pump nozzle for preventing dripping or leaking of liquid after a pre-determined amount of liquid has been dispensed. The attachment is configured for telescopically mounting on a dispensing end of a standard pump nozzle. The nozzle attachment has a hollow body and a spring-mounted valve moving in the hollow body between a normally closed position and an open position, allowing a flow of liquid, such as gasoline fuel, to be dispensed through a central opening of the nozzle attachment.Type: GrantFiled: August 8, 2006Date of Patent: October 27, 2009Inventor: John S. Treen, Jr.

Patent number: 7591393Abstract: A disposable drink-through dome lid for disposable drinking cups used in the sale of hot or cold beverages. In order to extend the volume within the cup, the top surface of the lid is elevated above the top surface of the beverage cup when in place, and is encompassed by an annular ridge that includes a generally oval-shaped opening for drinking. In its preferred form the ridge is not continuous around its perimeter but is partially recessed on both sides of opening. In its preferred embodiment the generally oval-shaped opening includes a barrier that projects downward from the opening's perimeter thereby providing shielding against accidental spillage due to sloshing of the beverage while transporting or consuming in a moving vehicle.Type: GrantFiled: January 31, 2005Date of Patent: September 22, 2009Inventor: Cleveland Benedict Crudgington, Jr.

Patent number: 7581572Abstract: A valve assembly disposed in a nozzle of a fuel-dispensing pump that, when in an open, operative position, freely allows fuel to flow therethrough. In a closed position, fuel is prevented from dripping from the end of the fuel-dispensing nozzle. A first embodiment provides a spherical or flat, spring-loaded one-way sealing element or check valve that is forced away from the dispensing end of the nozzle to allow fuel to flow therefrom. When fuel dispensing is complete, the check valve seals the nozzle. In a second embodiment, apertures in a cap are rotated between an open and a closed orientation to allow or block fuel passage depending upon their angular position. The valve assembly is press fitted into a conventional fuel-dispensing nozzle.Type: GrantFiled: July 26, 2005Date of Patent: September 1, 2009Inventors: Janet M. Sutera, Kenneth A. Lyman, Steven Palmatier
