Patent CA-2135953-A1 (CA)
Inventor: PETERSON JOHN P
IPC: G01R31/12
Filed: 1994-11-16
Abstract: To determine the stabilized surface insulation resistance (SIR) of a printed circuit board substrate and test printed circuit board is provided which has desirable clean surface conditions.  This surface which bears a predetermined circuit board test pattern has a known SIR characteristic resulting in a known stabilized SIR. The test board is then subjected to a soldering step which, in practice, is performed in the in-line production with commercial boards.  After the soldering step, the SIR characteristic of the soldered test board is determined for a time period sufficient for a comparison with the SIR characteristic of the clean test board to enable the stabilized SIR of the soldered test board to be determined.

Title: Method for producing steel
Inventor: AIZATULOV RAFIK
IPC: C21C5/35
Filed: 1993-05-26
Abstract: A steel making process is disclosed that utilizes solid ferrous metallic material as a substantial part of the metallic charge and uses heat released by combustion of two different types of carbonaceous materials and steel scrap (4) that have been strategically charged inside of at least a partially refractory lined steel making vessel (1). One of the carbonaceous materials contains a high content of volatile hydrocarbons and is primarily responsible for early preheating and partial melting of the solid ferrous material. The second carbonaceous material contains a low content of volatile hydrocarbons and is primarily responsible for providing a reducing capability to the slag, for carburizing the melt and for providing additional heat generated by combustion which is used to enhance heating and melting of solid ferrous materials.

Title: Apparatus for hitching a trailer coupler to a hitch ball
Inventor: RINES HUBERT M
IPC: B60D1/36
Filed: 1995-06-26
Abstract: An apparatus facilitating coupling of a trailer to a tow vehicle includes a barrier against which a hitch ball may be positioned in the first stage of a hitching effort.  The barrier includes clamps for barrier attachment to the trailer coupling.  Support rods and a support plate on the barrier serve to position the barrier rearwardly adjacent the coupler socket.  The barrier support plate may be inclined to abut a trailer frame having an inclined frontal surface.  To position the trailer coupler laterally into place above a hitch ball, a lever is provided which utilizes the hitch ball as a fulcrum.  An arm on the lever is engageable with the coupler to permit the application of force to move the trailer tongue and coupler into place above the hitch ball.  Lowering of a trailer mounted jack results in downward engagment with the coupler onto the hitch ball.  The barrier and lever are installed and removed without tools.

Filed: 1995-09-26
Abstract: The present invention provides an apparatus for limiting deflection of the armature shaft 38, 38', 103 of an electrically powered tool, such as a hand held saw 10 or drill 91.  In saw 10, the armature shaft 38, 38' extends as a cantilever from the motor 14 and has a geared connection 58, 60 to an arbor 44 for driving the saw blade 18.   An arrangement for limiting the deflection of the armature shaft 38, 38' comprises a pilot member 72, 84 and a socket 68, 82 associated, respectively, with one and the other of the armature shaft and a motor housing supported wall.  The socket 68,  82 is larger in cross-section than that of the pilot member 72, 84 and limits transverse deflection of the armature shaft 38,  38'  away from its axis of rotation A.  If the saw 10 stalls in the material being cut, force is transmitted from the geared connection 58, 60 to the armature shaft 38, 38'.  The socket 68, 82 and pilot member 72, 84 permit the armature shaft 38, 38' to deflect a predetermined amount to counteract torques resulting from the geared connection 58, 60. In one  embodiment,  the pilot  72  extends  from the armature shaft 38 to be received in an aperture 68 formed in the housing wall 66.  In another embodiment, the pilot 84 extends from the housing wall 66' to be received in a bore 82 formed in the armature shaft 38'. According to a third embodiment, in drill 91, the shaft deflection limiter is constituted by an armature shaft pilot 111 disposed in a roller bearing aperture 117.

Title: Self-release choker hook
Inventor: EWART JAMES M
IPC: F16G11/14
Filed: 1996-01-17
Abstract: A choker hook has a main body and a latch member rotatable relative to said main body. The latch member is biased by a spring thereby to form a pocket to hold the ferrule of a choker cable used in logging operations. The latch member has a toe piece which will contact the surface of a log when the choker hook is rotated by the choker cable relative to the log. The force between the toe piece and its attached latch member will tend to rotate the latch member relative to the main body when the effect of the force on the choker hook is such that the toe piece is brought into contact with the outside of the log. The ferrule pocket will open and the ferrule and attached cable will be released thereby releasing the log being transported without manual intervention at the point of log release.
