A velocity control device for controlling the velocity of a load on a flexible tension member. The device can include a chassis having a chassis peripheral surface, with a portion of the chassis peripheral surface defining an exit aperture. The device can also include a capstan, the capstan having a proximal face joined to the chassis and a distal face separated at a distance from the proximal face. A peripheral capstan surface can be tapered from a greatest diameter near the distal face to a smallest diameter near the proximal face. The device can include a throttle, the throttle being attached to the chassis. The throttle can an interior surface defining an opening through which the tension member can pass with the interior surface being in at least partial contact with the tension member. Heat produced by kinetic energy in the flexible tension member is transferred to the throttle, and the change in system internal energy produces work in the form of a drag force on the flexible tension member.

A mechanical coupling between a straight pipe end and a socket fitting comprises a seal ring and a locking ring disposed within the interior of the socket. The locking ring has a generally frustoconical shape with a plurality of corrugations extending circumferentially thereabout, the corrugations presenting inner edge portions engaging the outer annular surface of the pipe end and outer edge portions engaging the interior annular surface of the socket for opposing withdrawal of the pipe end axially outwardly from the socket. In an advantageous embodiment, the locking ring is assembled with a support disk to optimally orient the locking ring with respect to the fitting and the pipe end.

A micro motion poppet valve for a writing instrument provides delivery of ink with large pigment particles to a porous writing nib with minimal nib movement and relatively light actuation forces. The micro motion poppet valve includes a nib connected to a valve stem, the valve stem being connected to a valve plug. A valve body is integrally formed with a biasing element, which biases the valve stem towards a closed position. When a user presses the nib against a writing surface the valve plug moves away from a raised valve seat located on the biasing element to allow ink to flow from an ink reservoir to the nib.

A mechanical coupling between a straight pipe end and a socket fitting comprises a seal ring and a locking ring disposed within the interior of the socket. The locking ring has a generally frusto-conical shape with a plurality of corrugations extending circumferentially thereabout, the corrugations presenting inner edge portions engaging the outer annular surface of the pipe end and outer edge portions engaging the interior annular surface of the socket for opposing withdrawal of the pipe end axially outwardly from the socket. In an advantageous embodiment, the locking ring is assembled with a support disk to optimally orient the locking ring with respect to the fitting and the pipe end.

An electrically-conductive mesh spacer incorporated into the hydrogen and air gas flow spaces between each anode and cathode and its adjacent interconnect in a fuel cell stack. The mesh is formed of metal strands and is formed into a predetermined three-dimensional pattern to make contact at a plurality of points on the surfaces of the electrode and the interconnect element. The formed mesh spacer is secured as by brazing to the interconnect element at a plurality of locations to form an interconnect, which preserves the pattern during assembly of a fuel cell stack. The height of the formed pattern is greater than the height of a gas flow space after fuel cell assembly, such that the mesh spacer is slightly compressed during assembly of a fuel cell stack. Because the metal mesh is both compliant and resilient, the compressed spacer is continuously urged into mechanical and electrical contact with its electrode over all temperatures and pressures to which the fuel cell assembly may be subjected during use.

A NOX abatement system includes a first NOX adsorber capable of being disposed in-line and downstream of and in fluid communication with an engine. The NOX abatement system further includes a selective catalytic reduction catalyst disposed in-line and downstream of, and in direct fluid communication with, the first NOX adsorber. The selective catalytic reduction catalyst is capable of storing ammonia. An off-line reformer is disposed in selective communication with and upstream of the first NOX adsorber and the selective catalytic reduction catalyst. The reformer is capable of producing a reformate that includes primarily hydrogen and carbon monoxide.

In one embodiment, a flow switch can comprise: a deflector having a diverging upstream portion; an aperture located in a downstream portion of the deflector; and a divider disposed downstream of the deflector. The deflector can be capable of diverting a fluid stream that contacts the upstream portion, around the deflector. The aperture can be capable of allowing a flow of a displacing fluid such that the displacing fluid can inhibit the diverted fluid stream from converging to pass through the divider. The divider can be capable of allowing a flow of the displacing fluid therethrough.

In one embodiment, the method of producing a ceramic assembly includes: disposing an electrode precursor on an electrolyte precursor having an electrolyte sintering shrinkage, disposing a stabilizer precursor having a stabilizer sintering shrinkage on the electrode precursor on a side opposite the electrolyte precursor to form a precursor assembly, and sintering the precursor assembly to form the ceramic assembly comprising a stabilizer layer, electrode, and electrolyte. The difference between the electrolyte sintering shrinkage and the stabilizer sintering shrinkage is less than or equal to &#xb1;1% and a surface of the ceramic assembly has less than or equal to about 5.0 degrees camber, as measured from the horizontal plane.

A method for severing a solid-oxide fuel cell bi-layer element including a structural anode and an electrolyte layer, comprising the steps of orienting the bi-layer element such that the surface thereof is accessible to laser treatment; impinging a laser beam on the electrolyte surface; moving the impinged laser beam past the surface along a path in a plane corresponding to the desired severed edge to form a groove in the element extending partially through the element to a predetermined depth; and applying a bending moment across the groove to cause the element to break into first and second portions. The groove depth is preferably about 15% of the total thickness of the element.

A fuel cell module having four sheet metal parts stamped from flat stock. The parts do not require any forming operations such as folding or dishing. Each part may have a different thickness to suit its function. The first part is a cell mounting frame for receiving and supporting a PEN fuel cell element. The second part is a cathode spacer, the thickness of the spacer determining the height of the cathode air flow field. The third part is an anode spacer, the thickness of spacer determining the height of the anode fuel flow field. The fourth part is a separator plate for separating the anode gas flow in one cell from the cathode air flow in an adjacent cell in a fuel cell stack. The four plates are joined by welding or brazing and may be assembled in any order or combination which suits the assembly process. Any desired number of modules may be stacked together to form a fuel cell stack.
