  • Patent number: 5524662
    Abstract: A diaphragm-activated control valve and system for both refuel and running loss venting of a fuel tank to a vapor trap. The control valve is connected to fill control and rollover valves in the fuel tank, and defines a separate venting flow path for each valve to the vapor trap. The control valve is responsive to pressure conditions at the filler pipe inlet to alternately open and close the flow paths. During refueling the control valve vents the tank through the fuel-level responsive fill control valve. When the filler pipe inlet is closed, the control valve switches to vent the tank through the rollover valve. In a preferred form, the control valve includes a liquid fuel drain to prevent its being disabled by fuel entering from the filler pipe inlet via the signal pressure line during refueling. The drain includes a reverse flow check valve to prevent vapor venting out the drain path to the atmosphere during refueling.

  • Patent number: 5511272
    Abstract: A sacrificial link is disclosed for the shaft of a vehicle-cleaning brush unit, which link is pre-engineered to fail prior to the remainder of the shaft in response to bending forces exerted on the brush by a vehicle, for example. The shaft itself is therefore protected from permanent deformation or breakage, while the sacrificial link is easily removed and replaced with relatively little downtime and expense. In a preferred form the sacrificial link comprises a sacrificial shaft section having socket ends for removable connection to the upper portion of a brush shaft depending from a motor drive unit and the lower portion of the brush shaft connected to the brush, and a center region pre-engineered to fail before the upper and lower brush shaft sections. Novel clamping and release structure associated with the socket ends of the sacrificial shaft section is also disclosed.

  • Patent number: 5509538
    Abstract: A system and method for paperless, self-contained partial case picking of goods in a distribution center for cartons or containers subsequently shipped to a customer store. A set of cartons or containers is moved along a pick face in a series of move cycles. Operator display units provided at the pick face prompt workers to distribute goods from batches on the pick face to the cartons. The operator display units define contiguous put zones for each worker and assign each worker to particular batches of goods for each move cycle. The operator display units can include key entry means for the workers to signal the end of pick cycles, and in one embodiment to adjust pick quantities and distributions in real time according to changing circumstances. The put and pick zone assignments are reconfigured for each move cycle depending on factors such as worker ability and the picking difficulty of the batches assigned.

  • Patent number: 5503432
    Abstract: An improved fiber/resin composite tapered ski pole shaft and a method for making it. The shaft is hollow and is formed from a fiber/resin composite in which the resin is a thermoplastic material capable of being reheated and reformed. A straight, non-tapered, preformed shaft is heated at the lower end until the thermoplastic resin becomes workable, and then pressure is applied to taper the lower end of the shaft toward the tip. The shaft is held at a constant length during the tapering step such that the displaced thermoplastic material increases the wall thickness of the lower end of the shaft uniformly toward the tip. The rate of taper can be such that the tip becomes solid.

  • Patent number: 5492022
    Abstract: An apparatus for testing an industrial machine safety system that allows the machine to begin operation only when a plurality of safety push buttons have all been depressed, and that stops the machine's operation when any safety push button is released. The apparatus includes an artificial hand that can depress and, upon command, release one of the safety push buttons, and has a release detector for detecting the release of the artificial hand. The release detector operates optically. A lamp directs a light beam along a path that is blocked by a plunger when releasing the safety push button and not blocked when depressing the safety push button. A photodetector detects interruption of this light beam. Thus release of the safety push button is detected upon detection of interruption of the light beam. The machine begins to stop upon release of the safety push button. A motion detector detects the stoppage of the machine.

  • Patent number: 5481922
    Abstract: The design of transducers utilizing finite length sensor paths is discussed. Within the framework of linear elastostatics of an isotropic homogeneous material the normal, transverse, and shear components of strain along a path can be integrated over a finite length to separate and yield external loading components. These displacement measurements over a long distance accommodate the use of fiber optic displacement sensors. The use of optical interferometric sensors in contrast with electrical strain gauges, has the potential to allow the precision and range of the component measurement to scale with the geometry of the device rather than the maximum strain in the instrument. It becomes possible by virtue of these scaling properties to construct a better transducer. The design of transducers that measure all six resultant-load components using both electrical strain gauges and fiber-optic interferometric sensors are described. An advanced torsion sensor and a linear acceleration transducer are also discussed.
