Abstract: A frictional clutch for a motor vehicle includes a cover, a pressure plate, a biasing member, an adjustment mechanism and a dust shield assembly. The cover has an axis of rotation. The pressure plate is coupled to the cover for rotation therewith about the axis. The pressure plate has a frictional engagement surface substantially normal to the axis. The biasing member is interposed between the cover the pressure plate, and biases the pressure plate toward an engaged pressure plate position. The adjustment mechanism is centered about the axis and is located at a first radial distance from the axis. The adjustment mechanism is operably disposed between the biasing member and one of the pressure plate and the cover. The dust shield assembly includes an annular wall disposed radially within the adjustment mechanism. The annular dust shield assembly is in axial alignment with the adjustment mechanism.

Abstract: A frictional clutch for a motor vehicle includes a cover, a pressure plate, a biasing member, air adjustment mechanism and an annular shield. The cover has an axis of rotation. The pressure plate is coupled to the cover for rotation therewith about the axis. The pressure plate has a frictional engagement surface substantially normal to the axis. The biasing member is interposed between the cover the pressure plate, and biases the pressure plate toward an engaged pressure plate position. The adjustment mechanism is centered about the axis and is located at a first radial distance from the axis. The adjustment mechanism is operably disposed between the biasing member and one of the pressure plate and the cover. The annular dust shield is disposed radially within the adjustment mechanism. The annular dust shield is axially alignment with the adjustment mechanism. The shield is sized and oriented to protect the adjustment mechanism from debris radiating outward from a central area of the clutch.

Abstract: Fuel dispensers are converted to provide vaccum assisted recovery of vapors. Where previously provided with, or "plumbed" for, a pressure balance type of recovery system, the prior hose means is disconnected to permit mounting of a fuel driven, vacuum pump in communication with preexisting fuel and vapor conduit means. Where there has been no prior provision for vapor recovery, conduit means are installed to provide communication between the dispenser pedestal and a remote receiver for fuel vapors. One end of a coaxial hose, preferably of the inverted type, is mounted on the pump and the opposite end of the coaxial hose is connected to a vacuum assist nozzle.

Abstract: A vehicle identification system for use in a refueling station for identifying vehicle requirements, in which a control unit is located in a fuel dispenser for controlling functions of the dispenser such as fuel selection and activation of the dispenser's vapor recovery systems, and a driver circuit is located on the nozzle spout. The control unit communicates with the driver circuit through an intrinsically safe connection in a fuel hose and is programmed to periodically transmit a low power pulse signal to the driver circuit through this connection. The driver circuit includes a power generating means and an antenna for generating an RF interrogation signal in response to each pulse. The RF interrogation signal is detected by a transponder disposed on a vehicle adjacent the vehicle's fill pipe, when the nozzle is positioned adjacent to or in the fill pipe for refueling.

Abstract: A fuel dispensing nozzle is provided with a view glass/fuel flow indicator that are disposed between the main fuel valve and a downstream check valve. The view glass/flow indicator means comprise a pair of horizontally aligned view glasses. A plurality of embodiments illustrate the use of different sub-assemblies in providing the view glass/flow indicator functions, as well as different provisions for obtaining a seal that prevents leakage of fuel at the view glass units.
