Patent CA-2129192-A1 (CA)
Inventor: SHINJO KATSUMI
IPC: B21G3/12
Filed: 1994-07-29
Abstract: A metal rod (20) having a conical or pyramidal cut extremity (20a) is used to make a mandrel for blind rivets.    The rod is held in place between a pair of die segments (11) such that its end (26) of a preset length including the extremity is swageable and protrudes from an upper surface (14) of the segments.    Subsequently, the swageable end (26) is axially compressed to form a mandrel head (27) by a punch (12) which has a lower face (17) in parallel with the upper surface (14) of the segments and a conical or pyramidal recess (18) fittable on the extremity.    Thus, a free intermediate portion of the swageable end (26) compressed by the punch (12) swells radially to form the head (27) having a flat flange (31) from which the extremity protrudes as a lug (32) upwardly and centrally.    The mandrel, which has the head formed uniform without any eccentricity about the axis of a mandrel body, can now be produced inexpensively using the nail manufacturing apparatus, as in the prior art method.

Title: Load detection method
Inventor: NOBLE GARDINER A
IPC: F02P5/152
Filed: 1994-11-01
Abstract: A method for determining engine load of a spark ignition internal combustion engine. The method includes the steps of charging an ignition transformer to a maximum ignition charge and initiating an ignition discharge between electrodes of the spark plug. The ignition transformer is then charged to a predetermined diagnostic charge which is less than said maximum ignition charge. The diagnostic charge is discharged at a time of the combustion cycle where pressure in the combustion cylinder is dependent on engine load. The duration diagnostic discharge is then monitored and subsequently correlated to engine load. In this manner, the spark plug is used as a feedback element in determining engine load.

Filed: 1995-09-27
Abstract: An improved method of brazing of two unclad aluminum shapes, particularly for automotive heat exchangers, which brazing joint does not leave a physically apparent layer of brazing material and which effects a stronger, sounder autogenous joint.  A thin film of aluminum eutectic forming material (Si, Al-Si or Al-Zn) is deposited onto a zone of at least one of the shapes to be brazed or joined.  The shapes are placed in joining relationship to form an assembly with a joint at the zone. The assembly is heated to a temperature to diffuse the eutectic forming material into the aluminum members to form a sacrificial bond between the shapes at the joining zone. It is desirable that at least one of the unclad aluminum shapes to be joined is extruded tubing having a precise diametrical configuration and said film is deposited as a physically vapor deposited layer in a thickness range of 1-50 microns.
