Abstract: An elongated strip of flexible sheet material including at least one surface having a coefficient of friction relative to the surface of a golf ball and/or the striking surface of an associated golf club which is less than the coefficient of friction of the ball surface relative to the striking surface. The shank of a golf tee which supports the golf ball in a "teed-up" position passes through apertures in opposite ends of the strip to maintain the strip in encircling relation to the "teed-up" ball. The strip reduces the magnitude of lateral components of force frictionally transferred to the ball surface by the club striking surface when the ball is driven from the tee by an improperly executed drive thereby reducing the magnitude of a resulting slice or hook.

Abstract: An electronic hub odometer employs a permanent magnet and a magnetic reed switch for recording the number of revolutions of a vehicle wheel to which the odometer is mounted. A programmable integrated circuit electrically communicates with a clock crystal and the magnetic reed switch to automatically produce data relative to the time, distance and rate of travel of the associated vehicle. The data is stored in a random access memory integrated circuit. An infrared light emitting diode is employed for transmitting the data from the odometer to a remote unit. Information is also transmitted to the odometer from a remote unit via a photo-optical detector.

Abstract: A passive flow control valve assembly for controlling the flow of fuel through the fill pipe of an underground fuel storage system is disclosed comprising a valve housing mounted to the discharge end of the fill pipe, a valve assembly for controlling flow through the housing which is mounted for movement between a first open position permitting substantially unrestricted flow through the housing and at least a second position substantially restricting the flow through the housing, an actuator arm assembly for moving the valve between the first and second positions with the actuator arm being interconnected to the valve so as to progressively correspondingly move the valve from the first open position to the second closed position as the actuator arm moves from a first position to a second position, and a float assembly connected to the actuator arm for moving the arm responsive to the liquid level in the storage tank.

Abstract: A liquid level measuring device has an outer capacitance tube, an imperforate glass tube coaxially within the outer tube defining a capacitor annulus between them, and an inner capacitor sleeve coaxially within the glass tube and having separate longitudinally extending sleeve sections. The separate sleeve sections cooperate with the outer capacitance tube to form a plurality of capacitor sections each having a separately measurable value which varies between dry minimum and submerged maximum.

Abstract: A liquid level measuring system for the underground fuel storage tanks of a fuel dispensing station having a multiple segment capacitance probe in each storage tank and a microcomputer for periodically measuring the capacitance of each segment of each probe and calculating the level and volume of fuel in each tank using capacitance and volume calibration constants automatically updated by the microcomputer from the measured capacitance data and from fuel delivery data automatically fed to the microcomputer.

Abstract: Gasoline dispensing apparatus with cost and volume registers composed of banks of rotary electromagnetic indicators, each having an electromagnetic stator with a drive coil for indexing a respective rotary indicator wheel and a sensing coil for sensing wheel rotation and direction, and an indicator operating circuit for accumulating, and for indexing the indicator wheels for registering, the cost and volume of fuel delivered. The sensing coil is employed for monitoring and verifying wheel rotation and each indicator wheel is indexed by energizing the respective drive coil in the appropriate direction and for an optimum interval controlled by the respective sensing coil.
