Patent CA-2086302-A1 (CA)
Inventor: PETERSEN HORST U
IPC: B21D17/02
Filed: 1992-12-24
Abstract: The system increases the diameter to which pipe flanges can be flared. The tendency of the radial wall of the flange to crumple inwards is obviated by coining the transition corner of the wall. First, the pipe end is belled out to provide access for the coining punch. The belled-out end is then swaged back in, after the punch is removed. with the corner transition thus pre-conditioned, further axial pressure on the pipe with a suitable female punch causes the flange to expand diametrally in a controllable manner.

Title: Method of and apparatus for introducing an impregnating fluid into a porous substrate region
Inventor: MCGUIRE JAMES L
IPC: H01M8/02
Filed: 1991-08-28
Abstract: A method for making an impregnated fuel cell edge seal utilizing specialized tooling and modifying the exemplary carbon/graphite impregnant dispersion, which might include, for example, 66 %  carbon or graphite by weight, by adding to it a minor amount (e.g., 7 %) of a concentrated solution of ammonium hydroxide (e.g., about 58 % by weight of the NH4OH in water, equivalent to about 28-30 % by weight of NH3 gas added to water to make the solution) to the dispersion, increasing the pH of the impregnant up to a level of about of 10.5 to 11.5, improving the flow characteristics of the dispersion and decreasing the tendency of such a dispersion to solidify during the impregnation process. The modified impregnant is forced into the edge area of the electrode substrate (E.S.) of the fuel cell, producing an integral edge seal, using a specialized tool (10 or 10') having a rigid die (12) or a resiliently yieldable die (12') with a cooperating substantially rigid plunger (11 or 11'), which define between them an elongated chamber or channel (13 or 13') for the impregnant (30; see figs. 1-3 or 5). Such a tool (10 or 10') overcomes the effects of thixotropy, as the volume of the impregnant (30) is constrained by the volume of the chamber (13 or 13'), producing a seal which is uniform in density and dimensionally controlled by the shape of the channel (13), eliminating the varying shear forces of the prior art. The specialized tooling (10 or 10') can also be used to impregnate wetproofing material, particularly a fluorocarbon, into an electrode substrate to form corrosion resistant seals.

Title: Apparatus for cooling end regions of a stator core
Inventor: SARGEANT JOHN B
IPC: H02K1/20
Filed: 1993-04-15
Abstract: 56,889 ABSTRACT OF THE DISCLOSURE Disclosed  herein  is  a  generator  stator core including an apparatus for cooling the end regions thereof by employing radial and axial intersecting  passageways in the  stator  core  for  receiving  a  cooling medium.  The stator core comprises a plurality of spaced-apart adjacent packs formed  from a  plurality of  laminated sheets, well known in the art.  The invention adds to the  existing art an apparatus  that seals and isolates the intersections of the axial and radial passageways in a stator core.  In one example,  this  is  accomplished  by pre-forming the outer lamination of a  pack  so  that  it  is  bent  to  form an opening that conforms with the axial passageway and firmly engages the adjacent  pack,  thereby  isolating  the axial passageways from  the radial  passageways at the intersec-tion thereof.  In other examples, such isolation is caused by  placing  conduits  along the axial passageways between adjacent laminations.

Title: Electrode holder and electric sensor
Inventor: SCHLATTL WERNER
IPC: B23K11/25
Filed: 1993-10-18
Abstract: Abstract It is known to provide a welding electrode holder with a sensor for measurement of the force with which the electrode is pressed against a workpiece.  The sensor is connected to an electrical circuit controlling welding.  In this invention, the sensor comprises a light guide connected to the electrode holder so that elastic deformation of the holder corresponding to the electrode force changes the optical characteristics such as transmission of the light guide.  The circuit is responsive to these changes in the optical characteristics of the light guide.  This allows measurement of the electrode force close to the point at which the force is applied and allows changes in the electrode force to be measured during the course of welding. The sensor is robust and avoids problems of interference by electromagnetic fields.

Abstract: A heated catheter for monitoring cardiac output. Displaced from a distal end of a heated catheter (30) is a resistive heater (32) that heats blood flowing within a heart muscle (10). The resistive heater is mounted on the catheter so that when the catheter is inserted into the heart, the resistive heater is disposed in the right ventricle. A temperature sensor (34) is disposed downstream of the resistive heater, in or proximate the pulmonary artery during use. A  differential amplifier (40, 70) provides an electrical current to the resistive heater that varies as a function of the difference between the temperature of the resistive heater, measured by a temperature sensor (35), and a predetermined temperature. In another embodiment of the invention, a resistive heater (90) has a resistance that varies with temperature. The resistive heater comprises one arm of a bridge circuit (85). A differential ampli-fier (110) provides an electrical current to the bridge circuit in response to the voltage developed across the bridge circuit.
