Abstract:
A mechanically assisted electrical connector including a lever and a slider. The slider is coupled to the lever such that movement of the lever moves the slider. The slider defines a slot that is configured to cooperate with a post of a mating connector in a manner effective to urge the electrical connector and the mating connector together when the lever is moved from a first position to a second position. A ramp angle of the slot is varied to reduce a peak value of an applied force to advance the lever from the first position to the second position when connecting the electrical connector to the mating connector.
Abstract:
A fin characterized by a corrugated shape and configured to be interposed between adjacent instances of tubes of a heat exchanger assembly includes a plurality of planar portions, a radiused portion, and a retention feature. The plurality of planar portions is configured to extend between the adjacent instances of the tubes. The radiused portion is located between adjacent planar portions and is configured to be in thermal contact with a tube proximate thereto. The retention feature is located substantially mid-way between a leading edge and a trailing edge of the fin. The retention feature is configured to contact the tube in a manner effective to prevent fall-out of the fin prior to brazing of the heat exchanger assembly.
Abstract:
A two-pass evaporator suitable for use in an automobile includes various pressure drop devices to aliquot refrigerant into tubes that make up the two-pass evaporator. The two-pass evaporator includes a first pressure-drop device configured to receive and expand a liquid phase refrigerant into a first mixture of two-phase refrigerant; and a second pressure-drop device configured to receive and expand the first mixture of two-phase refrigerant into a second mixture of two-phase refrigerant and aliquot the second mixture of two-phase refrigerant to the first end of the first plurality of tubes. The two-pass evaporator includes a transition manifold that may house a flow-modulation plate disposed therein and configured to segregate the transition manifold into an upstream portion and a downstream portion. The flow-modulation device works in conjunction with the upstream pressure drop devices to aliquot refrigerant from the first plurality of tubes to the second plurality of tubes.
Abstract:
A heating, ventilation, and air-conditioning (HVAC) module adaptable to balance air delivered by the module to distinct zones includes a valve. The valve is configured to rotate about an axis to variably restrict air delivered to a first zone and a second zone. The valve defines a curved portion characterized as curved about and offset from the axis by an offset amount. An increase to the offset amount decreases a first portion of air delivered to the first zone relative to a second portion of air delivered to the second zone.
Abstract:
An arrangement for mounting of a mobile apparatus in equipment provided with a first movable support displaceable along a main axis, the first movable support being able to receive the mobile apparatus for it to be arranged in a location in which it is held in position by a holding device. The holding device is itself displaceable along a longitudinal axis between a retracted position in which the mobile apparatus can be placed in or removed from the location and an extended position in which the mobile apparatus is held in position in the housing. The equipment is in addition provided with a mechanical transmission means arranged between the movable support and the holding device so that the displacements of the mobile apparatus drives those of the holding device.
Abstract:
A communication plate extends along and is sandwiched between cylindrical communication manifolds of a first heat exchanger assembly and a second heat exchanger assembly. The communication plate includes a saddling surface arcuate in one direction and a saddling surface arcuate in the opposite direction for engaging in saddle-like fashion the cylindrical shape of the manifolds. The communication plate defines a plurality of communication plate orifices disposed along the communication plate and aligned co-axial with a plurality of communication orifices disposed along the manifolds to seal the communication orifices of the manifolds and establish distributed and sealed fluid communication between the heat exchanger assemblies.
Abstract:
An internal combustion engine includes a crankshaft rotatable about a crankshaft axis; a camshaft rotatable by the crankshaft about a camshaft axis; an engine cover defining an engine cover volume within the internal combustion engine; a drive member disposed within the engine cover volume which transfers rotational motion from the crankshaft to the camshaft; a camshaft phaser disposed within the engine cover volume which controllably varies the phase relationship between the crankshaft and the camshaft; an actuator which operates the camshaft phaser; and an actuator mount within the engine cover volume which mounts the actuator structurally independent of the engine cover, thereby allowing removal of the engine cover independently of the actuator.
Abstract:
A lead-lanthanum-zirconium-titanate (PLZT) capacitor on a substrate formed of glass. The first metallization layer is deposited on a top side of the substrate to form a first electrode. The dielectric layer of PLZT is deposited over the first metallization layer. The second metallization layer deposited over the dielectric layer to form a second electrode. The glass substrate is advantageous as glass is compatible with an annealing process used to form the capacitor.
Abstract:
A method to construct a tape wrapped unshielded twisted pair (UTP) cable is provided. The method includes the step of twisting a first wire and a second wire together to form a twisted pair. The method further includes the step of wrapping tape around the twisted pair with an effective amount of tension on the tape such that a separation distance between the first wire and second wire does not substantially vary along the length of the twisted pair.
Abstract:
A camshaft phaser includes an input member; an output member defining an advance chamber and a retard chamber with the input member; a valve spool moveable between an advance position and a retard position and having a valve spool bore with a phasing volume and a venting volume defined therein such that the phasing volume is fluidly segregated from the venting volume; and a phasing check valve within the valve spool. The advance position allows oil to flow through the phasing check valve and through the phasing volume from the advance chamber to the retard chamber while preventing oil from flowing from the retard chamber to the advance chamber and the retard position allows oil to flow through the check valve and through the phasing volume from the retard chamber to the advance chamber while preventing oil from flowing from the advance chamber to the retard chamber.
