  • Patent number: 4666058
    Abstract: A cap for closing the filler neck of a vehicle is provided. The cap includes a valve body and a vent adapted to allow a maximum amount of fuel vapor to vent to the atmosphere. The cap also includes a ball disposed within the valve body to seal the vent when the vehicle is rolled over to a substantially inverted position to prevent fuel from leaking from the cap. The cap further includes a baffle to prevent fuel from splashing through the vent when the vehicle is operated on a rough and uneven surface.

  • Patent number: 4629560
    Abstract: A regenerative fuel heating device is disclosed for heating fuel prior to the fuel being introduced into a fuel filter, fuel-water separator or both. The device includes a housing and a heater in the housing for heating the fuel. A space defining heat conductive barrier is provided for defining an upstream space in the housing into which fuel can flow to be heated prior to the fuel being introduced into the separator or filter and a downstream space in the housing through which the fuel can flow after the fuel has left the separator or filter. The heater and downstream space are placed in a heat transfer relation with the upstream space to enable the fuel in the upstream space to be heated by the heater and to extract heat from the fuel in the downstream space.

  • Patent number: 4498493
    Abstract: A pressure/vacuum valve assembly for a fuel tank filler neck comprises a pressure-release valve member, a vacuum-relief valve, and a pressure-release control member in a vent passageway. The vent passageway has an axially outwardly facing surface and a radially inwardly facing surface. A yieldable control spring urges the pressure-release valve member normally to close and seal the vent passageway. The pressure-release control member has an axially inwardly facing surface which forms a first restricted opening for the flow of fuel vapors. The control member has a radially outwardly facing surface which forms a second restricted opening with the radially inwardly facing surface of the vent passageway. The pressure-release valve member is urged in opposition to the control spring to open the vent passageway in response to a predetermined superatmospheric pressure and allow fuel vapor to flow in the first and second restricted openings.

  • Patent number: 4497290
    Abstract: A fuel system tester and primer includes a pump for pressurizing a fuel system, a fuel tank adapter, and a conduit for coupling the pump to the adapter. The fuel system tester and primer also includes a pressure release valve for venting excess pressure when a predetermined pressure is reached within the system, and a pressure monitor gauge for detecting pressure changes in a pressurized fuel system.

  • Patent number: 4497714
    Abstract: A fuel-water separator comprises a container having entry and exit ports and a progression of spaces through which the fuel moves. The spaces become progressively smaller and are arranged to direct the fuel through a series of downwardly and upwardly directed paths. The lower density fuel moves upwardly while the higher density water tends to move downwardly to drain through drainage openings provided in the lower portions of the spaces. Valves are provided for closing the drainage openings. The valves include float-valve balls which will release the water but hold the fuel. One of the spaces in the container includes a media having a downwardly directed surface upon which the water coalesces to move downwardly and through which the fuel moves to progress to the next space. Another one of the spaces includes a media providing a surface tension-discriminating surface through which the fuel will move and down which the separated water will move.

  • Patent number: 4475389
    Abstract: A radiator cap having an outer shell and a pressure vacuum valve assembly for closing the filler neck of a radiator includes a probe for detecting the coolant level in the radiator. The probe projects from the cap into the radiator interior and is electrically isolated from the radiator. An electrical connection is provided through the shell to connect the probe to a power source and indicator.

  • Patent number: 4476028
    Abstract: A fuel-water separator having a housing, and a heating element within the housing is provided with a sensor for sensing the presence of accumulated water within the housing above a specified depth. The sensor includes an electrically conductive probe which is hollowed to encase the heating element and mounted to project downward within the housing. A voltage source is provided for applying a voltage between the conductive probe and the housing. The housing and the voltage source are commonly grounded. An indicator is electrically interposed between the voltage source and the conductive probe.

  • Patent number: 4420392
    Abstract: In a fuel-water separator including entry and exit ports for fuel connectable in a fuel line supplying an engine and fuel flow paths between the ports for separating water from the fuel, the improvement comprises first and second passages leading to the exit port and a float valve ball for closing the first passage in response to the accumulation of a predetermined level of separated water. The second passage has a cross-sectional dimension which is substantially smaller than the first so that only restricted operation of the engine is permitted by virtue of a reduced fuel flow rate through the second passage when the first passage is closed.

  • Patent number: 4392507
    Abstract: A two-stage valve adapted for use in downward flow in the fuel line of a vehicle to provide roll-over protection, comprising a housing having two ball check valves axially disposed to normally check upward flow, the lower ball being expansion-biased spring-loaded, the upper ball being loaded with an expansion-biased spring resting upon the lower ball, the lower ball being larger than the upper ball, and the upper spring having a lower spring force than the lower spring.

  • Patent number: 4092038
    Abstract: A jacket for use in supporting an offshore platform. The jacket is of the type having a plurality of legs interconnected by a plurality of bracing members, a number of the bracing members having means for connection with the cables of apparatus for lifting the jacket during transportation and positioning thereof. The jacket has improved connection means comprising a plurality of self-aligning, reusable padeyes and a corresponding plurality of padeye mounting sites. Each mounting site comprises a cylindrical padeye receiving portion comprising a section of a bracing member, and is bounded axially by stop means. Each padeye comprises a pair of hinged, generally hemispherical clamp members which, when closed, form a cylindrical hollow sized to fit the receiving portion. An eyelet is rigidly mounted on each clamp member and defines a hole for receiving a pin and a stop surface.

  • Patent number: 4022887
    Abstract: The use of edible cyclotriphosphates and cyclotetraphosphates as phosphorous supplements in diets effectively inhibit the development of caries. The compounds may be incorporated in candies, for example, caramels, they may also be imbedded in fat particles, which in turn are distributed throughout a food composition such as a cereal.
