Abstract: A cast aluminum burner base has a tubular inlet communicating with a cavity formed in an enlarged diameter flange remote from the inlet. The cavity is closed by a cast aluminum cap registered against the base. The base and cap are each castellated along the parting line such that the castellations are interdigitated. Grooves having semi-circular cross sections and formed radially across the castellations and the spaces between and close on the parting line to form circular cross section primary flame-generating ports. The castellations on the cap are truncated and tapered to provide flame stabilizing passages adjacent alternate flame-generating ports.

Abstract: A connector receptacle for simultaneously converting a plurality of individual wire leads in bayonet plug-in connection with a mating multiple pin wire harness connector. A conductive insert stamped from flat sheet stock has individual crimp-type wire lead terminals formed integrally therewith and extending outwardly from the margins of the insert. A plurality of barbed pin-receiving apertures are formed in the insert. Slots formed in the sheet stock form frangible webs interconnecting the material surrounding each of the barbed apertures. The insert is encapsulated with dielectric material preferably by molding and access openings in the dielectric material permit subsequent removal of the frangible webs to form individual electrically isolated connectors about each of barbed apertures.

Abstract: A two-stage venting on-board refueling vapor recovery (ORVR) valve for controlling fuel tank venting to a storage canister during tank filling. A float actuated poppet has a small second stage venting hole therethrough. The poppet is mounted for relative movement with respect to a second stage vent valve member disposed on the float. During tank filling, venting is through a first stage relatively large flow area passage until rising fuel level causes the poppet to close the first stage vent flow area. Venting during continued filling is through the second stage venting hole in the poppet. After first stage valve closure relative movement or lost motion occurs between the first and second stage valve members.

Abstract: A lever switch, in particular a steering column switch for a motor vehicle, comprises a housing (1) with connector contacts (5), a switch lever (10) supported in the housing (1), a switch element (30 and 32, respectively) actuated by the switch lever (10) and acting on switch contact paths (24), and comprises a switch gate (14), which resets the switch lever (10) or locks it in position. In order to provide a lever switch offering variable switching functions while permitting an economical and cost-effective manufacture at the same time, a predetermined layout of switch contact paths (14) is used for the implementation of different lever switching functions in that the division of the switch contact paths (24) is different, that the association and/or values of the resistors (25) relative to the switch contact paths (24) is different, and that different, interchangeable switch gates (14) are used.

Abstract: An improved thermally responsive expansion valve for use in controlling flow of refrigerant in a circulating system has a cartridge sub-assembly with a fluid charged diaphragm capsule, an operating rod mechanism, a valve seat and captured valve obturator. A tubular extension with the valve seat is adjustably threaded onto the capsule. The cartridge subassembly may be thermally pre-calibrated before installation in a blind bore in a valve body. During calibration, the tubular extension is rotated to adjust the diaphragm and operating rod mechanism to provide the desired obturator movement from the valve seat at the calibration temperature.

Abstract: A power window switch (1) for a motor vehicle comprises an actuation element (2) which is pivotally supported in a housing (6) and actuates switch contacts (57) by means of a corresponding sliding contact element (35), whereby said switch contacts are associated with connector contacts (53). In the pushing direction for the downward motion of the window, as well as in the pulling direction for the upward motion of the window, the actuation element (2) is respectively associated with a two-step pivoting motion (19), whereby the actuation element (2) acts on deflecting means (38, 78) to effect a linear back and forth motion of the sliding contact element (35), which successively actuates two switch contacts (57) of a switch matrix (49).

Abstract: A rotary solenoid operated valve assembly having the rotary journalled in a ball race in one end of a tubular pole piece extending through a coil. The tubular pole piece has the end distal the ball race received in the bottom of a cup-shaped stator which has salient poles on the open rim and which define radial air gaps with poles formed on the rotor. A cam formed on the rotor moves a ball valve member in a direction transverse to the rotor axis for controlling flow over a valve seat provided in an inlet or outlet port. The rotor is balanced about its axis of rotation to prevent cam movement when the valve is subjected to vibration in a direction transverse to the rotor axis.

Abstract: A latchbolt assembly having a carrier with a solenoid operator mounted on the carrier is slidably received in a base or mounting cap with an annular groove formed in the carrier with a projection formed in the groove at a vertically downward location. A split ring is received in the groove with the projection orienting the gaps in the split ring and the split ring is compressed radially for sealing between the carrier and a base. A latchbolt is slidably received in the carrier and is connected to the solenoid armature for movement to the unlocking position upon energization of the solenoid. A cable extends through the housing and armature and is connected to the latchbolt for manual retraction by the user pulling on the cable. The latchbolt assembly is particularly suitable for motor vehicle fuel filler door latching applications.

Abstract: An electrically controlled vacuum operated fuel vapor canister purge valve having a regulator valve subassembly with a vacuum signal chamber on one side of a pressure responsive power diaphragm which moves a regulator valve obturator for controlling flow from a vapor inlet passage to a vapor outlet passage for connection to an engine inlet. The vacuum signal chamber has a vacuum signal connection port and a recess or well with an atmospheric vent port and resiliently deflectable locking tab. A solenoid operated atmospheric bleed valve has a boss with a restrictor outlet which is quick-connected and seated in the well for electrically controlling vent flow into the vacuum signal chamber. The restrictor limits atmospheric bleed flow to attenuate the effects of sudden changes in the vacuum signal.

Abstract: A motion transducer having a user moveable plunger which compresses a spring for generating a force proportional to plunger displacement and applying the generated force to an actuator telescoped onto the plunger. The actuator has an elastomeric pad on the surface which contacts and reacts the generated force onto a force/pressure sensitive resistive strip which varies its resistance with the changing force applied by the elastomeric pad. The changes in resistance may be electrically detected to give an indication of plunger travel.

Abstract: An apparatus (10) allows atmospheric pressure into an environmentally sealed enclosure for creating an equilibrium that allows a sensor (28) make a proper measurement. A slot or opening (26) in the cover (14) exposes outside atmospheric air to a restricted portion of a gas permeable membrane (18). The membrane (18) allows a selected gas to pass through the membrane (18) creating the equilibrium in the housing (12). A gasket (16) positioned between the cover (14) and housing (12) seals the housing in an air tight manner except for the gases allowed in through the membrane (18). Pressure sensor (28) can then make a more accurate measurement. Apparatus (10) finds particular utility in a low pressure tire management system.

An interchangeable vent float valve subassembly is attached to the end of the neck before attachment of the extension to the header and assembly on the tank. Tanks of different depth can be accommodated simply by using extension members having a correspondingly different length necks, while the float valve subassembly and header are interchangeable.

The axial pole segment extensions provide increased total flux for a given motor volume without an increase in ampere turns of electrical energization. The motor of the present invention is particularly suitable as an engine air throttle actuator.
