Abstract: A combination refrigerant expansion valve adapted for operation by a thermally responsive element, and a solenoid actuated, preferably pilot operated inlet shutoff valve. The solenoid has a resilient elastomeric stop-ring for cushioning deceleration and limiting travel of the armature to prevent closing of the working air gap between the armature and a pole piece. The armature also has a cross port therethrough to alleviate flow-induced pressure decrease on the distal end of the armature from causing the armature to stick in the actuated position when the coil is de-energized.

Abstract: A corrosion and ultraviolet ray resistant composite coated article (46) for use in or to contain electrical equipment is made by first cleaning an uncoated article (10) at a cleaning station (14), and then successively passing the cleaned article through wash workstation (16) phosphate bond coating workstation (18), wash workstation (22), non-chrome sealant coating workstation (24), drying workstation (26), heating workstation (30), epoxy resin coating workstation (34), and exterior painting workstation (40) by any type of transport system (12, 36), where the epoxy coated article can be passed again through previous workstations (14, 16, 18, 22, 24, 26, 30, 34) before final painting at workstation (40).

Abstract: A fuel tank has a recess formed on the inner surface of the upper wall. A vent valve has a mounting portion extending therefrom with a resiliently deflectable disc formed thereon and a guide disc spaced from the deflectable disc. Upon insertion into the recess the deflectable disc is deflected and the periphery thereof frictionally engages the inner surface of the tank wall recess. The guide member slidably fits into the recess to prevent lateral movement of the mounting portion and removal from the recess.

Abstract: The float has an elastomeric valve disk with an annular bead rim caged for limited lost motion movement on the top of the float. A rigid backing plate for the valve disk is pivoted on a curved surface on the top of the float to ensure self-alignment of the valve disk on the vent port seat when the float is moved upward by the rising liquid level for closing the vent during refueling. As fuel is used from the tank, the float drops and the angled top of the cage contacts the bead rim on the valve disk and effects a peel-away re-opening of the valve.

Abstract: A conductive heat sink is electrically interposed between a fuse and a switching apparatus within a watertight case of a network protector. The heat sink is advantageously configured to conduct current between the switching apparatus and the fuse. During operation, the skin effect causes the electricity conducted by the heat sink to flow primarily through the outer regions of the heat sink, thereby resulting in the generation of heat at the outer regions of the heat sink due to electrical resistance. The heat sink includes a core from which a plurality of fins extend. The fins conduct and convect heat away from the outer regions of the heat sink, which reduces the temperature thereof and correspondingly increases the conductivity of the outer regions of the heat sink.

Abstract: A rocker arm assembly for a valve train includes a hydraulic lash adjuster for accommodating slack in the valve train. There is also a lost-motion connection preferably between the axle of a roller which is operated upon by a cam and the rocker arm itself. Excessive expansion of the lash adjuster will not prevent closing of the valve because the closing movement is accommodated by the lost-motion connection. A spring is provided to maintain the lost-motion connection despite the tendency of the hydraulic lash adjuster to expand. Greater tolerance in the cam base circle radius is allowed, permitting the use of net-shaped cams.

Abstract: A load bearing solenoid operated valve having a one piece body with threads on opposite ends thereof for connection to a system placing the valve in tension or compression. An inlet port is formed in one end of the body and a plurality of cross ports are formed to communicate with the inlet. A sleeve valve/armature member which is magnetizable is slidably received over the body and has radial ports which are moved axially for valving the body cross ports. An annular flux collector ring and a pole piece are disposed on the body on opposite axial sides of the sleeve valve. A bobbin with coil thereon is received over the body and sleeve and a magnetically permeable cover over the coil completes the flux loop about the coil.

In the preferred embodiment the diffuser comprises a plurality of radially extending flow channels formed adjacent the inlet shutoff valve seat integrally in a one-piece valve seat member.

Abstract: A circuit breaker has a set of remotely controllable secondary contacts electrically connected in series with the main contacts which provide overcurrent or fault current protection. An operating mechanism opens and closes the set of main contacts. The secondary contacts are opened and closed by a latching solenoid. The latching solenoid includes a plunger latchable to a first position, which opens the set of secondary contacts, and to a second position which closes the set of secondary contacts. The latching solenoid also includes an open/close coil which when energized with a first polarity signal operates the plunger to the first position and which when energized with an opposite second polarity signal operates the plunger to the second position. A circuit is structured for cooperation with a remote control circuit for energizing the coil with the first polarity signal or, alternatively, the second polarity signal.

Abstract: A rotary transformer includes a resonant circuit and a coil drive circuit. The resonant circuit includes a resonating capacitor connected to a power MOS transistor, coupled across the primary coil of the transformer. The coil drive circuit includes a diode connected to a power MOS transistor coupled across the primary coil of the transformer. A microprocessor detects changes in the voltage across the primary coil. The resonant circuit is connected and disconnected from the transformer during a power transfer mode and a data transfer mode, respectively. During the power transfer mode, stored energy in the leakage inductance of the primary coil is used for power coupling, via the resonant circuit, instead of being dissipated as heat. The resonant circuit is disconnected from the rotary transformer during the data transfer mode to maximize bandwidth for two-way data transfer between the primary and secondary sides of the transformer.

Abstract: An detection system emits a light beam and has a photodetector that senses when light is reflected by objects to be detected. Because reflectivity of the objects varies greatly, the intensity of the reflected light varies over a large range. To prevent false object detection, an automatic sensitivity control mechanism is provided which controls the intensity of the emitted light beam and attenuation of the signal from the photodetector. That control is in response to the level of the photodetector signal.
