Patent CA-2076423-C (CA)
Title: Nut with deformed internal thread, and method of using same in bolt assembly
Inventor: RASTALL DONALD E
IPC: F16B13/14
Filed: 1992-08-19
Granted: 1995-07-25
Abstract: A nut for use in a bolt assembly having an adhesive anchoring capsule for attaching roof or wall supports to the rock structure of a mine. The nut has deformities in its continuous internal thread that cause the continuous internal thread to bulge inwardly toward the axis of the bore. The deformities limit the advance of the nut upon a bolt and are formed by stamping dimples into one face of the nut. When an overcoming torque is applied, the deformities in the continuous internal thread are pushed radially outwardly and the nut is allowed to further advance upon the bolt. Because the deformities do not form a break in the thread, which remains continuous, no fragments are formed to damage the bolting tool, and the bolt thread remains undamaged so that a second nut can be threaded on it to hold a screen or the like.

A submerged vertical burner tube extends downwardly from the vent plenum and has an open lower end extending into a submerged turn bowl disposed at the bottom end of the tank interior.  Extending upwardly from the turn bowl within the tank interior are a plurality of vertical flue tubes that communicate the interiors of the turn bowl and the vent plenum.  A vertically elongated perforated conical burner is disposed within the burner tube and is supplied with a throughflow of a pressurized fuel/air mixture that is ignited by an igniter mounted on the top end of the burner.   During operation of the water heater, hot combustion products discharged from the conical burner are sequentially flowed downwardly through the burner tube into the submerged turn bowl, upwardly through the flue pipes into the vent plenum, and then outwardly through the vent plenum outlet passage.

Title: Method and apparatus for registering multiple images in a color xerographic system
Inventor: ANDREWS JOHN R
IPC: G03G21/00
Filed: 1994-06-13
Granted: 1997-04-29
Abstract: A method and apparatus is provided for registration of color images on a photoreceptor belt.  Registration is accomplished by forming, in one embodiment, a chevron-shaped registration marks in non-image areas of the belt.  A Raster Output Scanner (ROS) sweeps an output beam across the belt's surface.  The beam is modulated in accordance with input video data to form successive color images.  An unmodulated beam is also swept across the registration marks, each mark being successively swept by a plurality of beams.  With each crossing of the legs of the chevron, two signals are generated by an associated sensor and stored in an averaging and extrapolation circuit.  The multiple signals are compared and detection of the intersection is calculated by an extrapolation method.  The averaging circuitry generates a registration signal which is used to enable an accurate start of page signal, to correct for skew and to adjust for errors and line-to-line spacing between lines in a color image frame.
