摘要： An endodontic instrument and method for making same is provided. A rod of superelastic material is set into a shaped configuration to form an instrument, such that the instrument may be inserted into a root canal in a configuration different than the shaped configuration and revert towards its shaped configuration during the endodontic procedure.

摘要： An in-dispenser leak pan provided inside the housing of a fuel dispenser. The leak collection chamber collects any fuel that leaks from fuel-handling components located inside the fuel dispenser above the pan. The pan is secondarily contained by an outer pan or container such that an interstitial space is formed therebetween. If a breach exists in the top part of the pan, the captured leaked fuel will be contained in by the outer pan in the interstitial space. The interstitial space of the pan is drawn under a vacuum level using a vacuum-generating source to monitor for leaks. If a leak is detected, a control system may generate an alarm and/or cause the submersible turbine pump to stop supplying fuel, or cause the dispenser product line shear valves to close, thereby only stopping fuel flow to the individual fuel dispenser containing the leak.

摘要： A fluteless endodontic file is provided, formed from a tapered shaft of material having a prismatic shape generally defined by three or more side surfaces and three or more interposed corners. A plurality of notches are cut into one or more corners defining cutting surfaces, points and/or edges. The notched cutting surfaces are formed such that the file, when rotated and/or reciprocated within a root canal, effectively cuts/debrides hard tissue (known in the art as dentin) as well as soft tissue, thus, forming an optimal canal shape. The cutting surfaces are also preferably formed at an angle to the centerline of the instrument to provide optimal cutting efficiency and material removal. The fluteless file design exhibits increased efficacy, with less tendency to bind and break within the root canal and also significantly reduces manufacturing and capital equipment costs.

摘要： The present invention provides enhanced security to internal components in a main access compartment of a fuel dispenser. Both a primary lock on a main panel, that secures the main access compartment, and a hidden second lock, hidden inside a lower compartment of the fuel dispenser, must be bypassed to gain access to the internal components, thus providing enhanced security. The lower compartment is also protected by a lock, which must be bypassed in order to gain access to the hidden second lock in an attempt to bypass the hidden second lock. This locking arrangement provides greater security than prior art methods since three locks, including a hidden lock, must be bypassed to breach security and gain access to the internal components in the main access compartment of the fuel dispenser.

摘要： A leak collection chamber is provided inside the housing of a fuel dispenser. The leak collection chamber collects any leaked fuel from fuel handling components inside the fuel dispenser so that the fuel does not leak to the environment. The leak collection chamber can be removed form the fuel dispenser for evacuation. The control system inside the fuel dispenser can determine the liquid level inside the leak containment chamber and generate signals and alarms if the liquid level exceeds a threshold liquid level value and/or the rate of increase in liquid level exceeds a threshold liquid level increase value. The control system can alert service personnel and/or other systems of the leak collection chamber liquid level. Further, the control system and/or other systems shut down the submersible turbine pump that services the fuel dispenser with fuel in response to catastrophic leak condition.

摘要： A flow switch used in conjunction with a fuel meter in a fuel dispenser to determine when fuel is flowing. A flow switch can only be activated if fuel is flowing through the flow path of the flow switch. If fuel is flowing as indicated by the fuel flow switch, but the meter is not registering fuel flow, there is a meter error, which may be an error internally with components of the meter and/or a pulser that generates pulse signals indicative of fuel flow. If the meter pulser is registering fuel flow, but the flow switch is not registering fuel flow, then an error exists with the flow switch. If fuel is flowing and there are no errors, both the meter and the flow switch should indicate fuel flow.
