Abstract: A method and apparatus for dynamically monitoring in real-time the operation of a press machine and tooling during actual production operations, in order to evaluate the true interaction between actual vibration activity occurring at multiple locations within the press machine geometry. A configuration of accelerometers is used to acquire measurement data indicating the acceleration of the press machine and for tooling at a plurality of press machine locations. An integrator converts the acceleration data into displacement data representing the displacement activity of the press machine at the indicated machine locations. Filtering the displacement data provides deflection measurements representing the vibrational activity occurring at the relevant machine and tooling location. Measurements of the relative press motion activity between selected machine locations provide an indication of the influence that deflection activity occurring at respective press machine locations has on one another.

Abstract: A method and apparatus is disclosed for sensing hydrocarbon in the vapor path of fuel dispensers using a fiber-optic sensor. The sensor includes an absorber-expander sensing structure mechanically coupled to the fiber body and responsive to the presence of effluent fuel components for absorbing the hydrocarbon therein and expanding in response thereto. The expansion activity has the effect of generating a microbend deformation in the fiber, producing detectable changes in the optical throughput representing the concentration of hydrocarbon that is sensed by the absorber-expander element. The fiber-optic sensor is particularly useful in a vapor recovery system by providing an optical signal that is representative of the ambient hydrocarbon concentration.

Abstract: A crescentless internal gear pump includes a housing with an intake connection and a pressure connection. An internally toothed internal gear has an outside surface and is disposed for rotation within the housing. Each tooth includes a head and a base, the internal gear having radial openings that form a conducting connection between a tooth base and the outside surface. A pinion, which is rotatably disposed within the housing and meshing with the internal gear, has teeth with each tooth including a head. The teeth of one of the internal gear and pinion, includes a profile groove with a base provided in the heads into which a sealing element is disposed and which slides on an opposing tooth head. The sealing element has a sealing surface and includes a channel that produces a conducting connection between the profile groove base and the sealing surface. The sealing element is slightly movable in the profile groove in the radial direction to form a controlled gap.

Abstract: A mechanical press having a wet or oil shear clutch/brake drive unit is provided including elimination of undamped clearances. Lubrication oil utilized in the press flywheel bearing is ported and communicated into the clutch brake unit for use therein, eliminating the use of two separate lubrication or oil transport systems. A hydrostatic oil bearing on the brake/clutch actuator member (actuation plate) eliminates the use or need of an anti-friction bearing between the actuator member and the brake and clutch members.

Abstract: A method and system for detecting leaks in a fuel dispenser is operative to pneumatically pressurize a selectable one of a vapor recovery portion and a fuel dispensing portion using a compressed air flow. A flowmeter measures the flow rate of the compressed air communicated to the fuel dispenser for pressurization thereof. A processor provides an indication of the leakage condition of the fuel dispenser based upon the pneumatic flow rate measured by the flowmeter which satisfies a pressurization condition for the fuel dispenser, such as maintaining the pressurization level above a threshold value. The flow rate of compressed air needed to maintain this pressurization level is indicative of the leak rate.
