摘要： A one-piece molded plastic lamp fixture for mounting a light bulb at the exterior of the clamping shell portion of an electric cigar lighter for vehicles, to provide illumination of the socket thereof. The clamping shell has a light-admitting aperture over which the bulb is positioned when carried in a body part of the plastic fixutre. An integral plastic hood is connected to the body part adjacent the bulb, and can be swung from a first position overlying and generally concealing the bulb, to a second position wherein the bulb is exposed for replacement. The body and hood portions are joined by a living hinge, and the body portion is held on the clamping shell by resilient, opposed integral retainer fingers that are receivable in openings in the shell. The hood portion has integral ears which underlie and back up the retainer fingers when the hood is swung to its first position whereby inward movement of the fingers is limited to prevent the fixture from becoming inadvertently loosened from the clamping shell. The hood and body portions, and hinge can all be molded as a single integral plastic or nylon piece.

摘要： An electric heater assemblage for attachment to the air intake opening of a fuel vapor recovery canister of the type containing material adapted to alternately adsorb and store, or release fuel vapor. The assemblage includes a wafer of electric resistance heating material, and electrical connections for effecting energization of the wafer. The wafer has opposite expansive surfaces, and there is a first wall located at one side of the wafer and having an expansive surface coextensive with one wafer surface, and a second wall located at the opposite side of the wafer and having an expansive surface coextensive with the other wafer surface. The first wall and wafer thus define a first chamber, and the second wall and wafer define a second chamber in communication with the first chamber at the periphery of the wafer. A housing that carries the wafers and walls directs air from the exterior of the canister into the first chamber, past one side of the wafer and its periphery and into the second chamber, past the opposite side of the wafer and thereafter to the interior of the canister, for imparting heat to the adsorbent material contained therein. The arrangement is characterized by both high efficiency and low cost.

摘要： A device for the recovery of fuel vapors originating in the fuel system of a vehicle, particularly at the gas tank thereof or in the carburetor float bowl. In one arrangement, a fuel vapor line connects the fuel tank to an input port of a fuel vapor storage and recovery canister containing activated carbon or charcoal, with another port thereof, referred to as a "purge" port, being connected with either the engine intake manifold or else a vacuum port of the carburetor. Carried by the canister is a self-regulating electric heater assemblage adapted to heat air flowing into the canister through a large air port, thereby to also heat the charcoal. When the vehicle is idle, fumes from the gasoline tank can enter the input port of the canister to be adsorbed and stored by the charcoal. When the vehicle is operated, vacuum from the intake manifold draws air into the canister, causing the heated charcoal to release its stored fuel which is then burned in the engine. The heating action hastens the release of the stored fuel from the charcoal. Otherwise at low temperatures this release would occur very slowly. The end result is less pollution emitted into the atmosphere from the vehicle's fuel system.

摘要： A fuel vapor recovery canister having a housing including an outer wall with spaced-apart vapor ports. Adsorbent material in the housing adsorbs and stores fuel vapors entering one vapor port, or under other circumstances releases such vapors for exit through one of the ports. In one embodiment the housing has interleaved baffle plates between the ports, which force vapors entering one port to flow along a serpentine path, giving maximum exposure of the vapor to the adsorbent material. In a second embodiment, a helical partition is provided, similarly forcing vapor flow to occur along a serpentine path.

摘要： A float switch construction for monitoring liquid levels, comprising a float housing having a float member which is movable therein between raised and lowered positions. In the housing there is a fixed contact member and an asymmetric, elongate movable contact member, the latter having a laterally offset portion constituting a gravity-responsive mass. The housing has an electrically conductive bearing which mounts the movable contact member for both turning and pivotal movement and for conducting current to or from it. The float member and movable contact member are freely turnable with respect to one another, and have cooperable engaging portions for causing the movable contact member to pivot in response to movement of the float member. The fixed contact member has contact portions disposed annularly for engagement by the movable contact member in response to its pivotal movement irrespective of the angular orientation of the float housing. Engagement of the contact members controls a circuit from the fixed contact member to the bearing.

摘要： A liquid level gauging system and sensor device for installation in the aperture of a wall of a liquid-containing vessel, including a metal fitting having a through bore and a substantially cylindrical body portion with external threads by which it can be secured in the aperture in the vessel wall, a cup-like enclosure disposed in the bore, the enclosure having a bottom wall containing a prism disposed adjacent the inner end of the bore, and a light source and a light-responsive device mounted in the enclosure. The prism has a substantially conical forward end portion for immersion in the liquid to be monitored. The conical forward end portion of the prism is characterized by an axis, and the prism has a light-admitting and light-transmitting conical recess coaxial with the conical end portion of the prism. Light rays from the source that pass into the surface of the conical recess are bent, by refraction, toward the conical end portion. Reflected rays from the conical end portion passing outwardly through the surface of the conical recess are similarly bent, by refraction, toward the light-responsive means. Especially high resolution and accuracy are possible, while maintaining good reliability and repeatability.

摘要： An electric switch construction having a body member with a a stationary electrical contact, a movable plunger in the body member and carrying a second electrical contact, and a compression spring, one end of which is carried by the plunger. The other end of the spring preferably carries an abutment or button, intended for engagement by an actuator, such as the hood of a motor vehicle. The spring constitutes a yieldable drive or link between the actuator and plunger, to compensate for dimensional variations that normally occur in the environment in which the switch is used, as well as minimizing deleterious effects of high impulse forces that would otherwise be applied by the actuator to the switch plunger, and also the effects of overtravel of the actuator. Improved reliability and longer switch life expectancy are thus realizeable.

摘要： An exhaust gas purification device for installation in the exhaust line of an internal combustion engine of a vehicle, for igniting and vaporizing particulate matter in the exhaust stream. The device includes a canister having a tubular casing with an open end, and an end fitting having a wide mouth which fits against the open end, and thereby closing off the same. The fitting has an inlet port for connection to the exhaust pipe of the engine. Disposed within the casing is a porous filter element which traps small amounts of solid matter such as soot, and keeps it from entering the atmosphere through the vehicle's tailpipe. Igniting devices in the canister adjacent the inlet side of the filter, are located along the exhaust stream flowpath. Upon contact with the igniting devices, at least some of the particulate matter in the stream is vaporized, and passed, as a gas, through the filter. The arrangement prevents clogging of the minute openings of the filter with relatively large particles, which would otherwise block the exhaust flow and cause malfunction of the engine. The device is especially well suited for use in diesel engines, to vaporize carbon (soot) in the exhaust stream.
