Title: Intake Device in Engine for Outboard Engine System
Inventor: TSUNODA MASAKI
IPC: F02M35/12
Filed: 1996-05-17
Abstract: A V-shaped multi-cylinder engine is mounted in such a manner that a crankshaft  is mounted  in a vertical attitude and cylinders are opened into a V-shape in a rearward direction.  An intake silencer is mounted above a throttle body which is disposed in front of a crankcase portion of the engine.  The intake silencer includes an intake silencing chamber defined by a belt cover which covers a belt of a valve operating mechanism and by a lower wall member.  Two left and right air intake pipes extend downwardly from the intake silencing chamber and open into an engine compartment.   A single intake-air introducing pipe extends downwardly from the intake silencing chamber and is connected to an upper end of the throttle body.

Title: Heat controlling system for cold weather engine operation
Inventor: WIREMAN ALONZO
IPC: F02N19/10
Filed: 1996-05-31
Abstract: The present invention discloses a heat controlling system for use with the cooling system of heavy machinery.  A network of adjustable louvers selectively blocks the flow of heated air from the exhaust of a cooling system and directs the heated air through a control ducting system that recirculates the air back to the intake of the cooling system.  A dampener controls the amount of air allowed to flow through the control ducting system.  The heated air provides additional heat to cooling systems which are not generating enough internal operating temperature to successfully operate in cold weather conditions.

Abstract: In a microscopic screening apparatus a calibration slide (28) is mounted on a stage (18) of a microscope (36), and a microscope positioning system is calibrated by reading and storing (1008) in memory the location of at least one fiducial marking that is on the calibration slide (28) using a microscope-dependent coordinate system. Next, a sample containing slide is mounted against the stage (18) of the microscope (36). The location of at least one feature on the sample containing slide is then transformed (2006) into a microscope-independent coordinate system, and is stored (2008) in a memory. Using a second microscope (36), a second calibration slide (28) is mounted against the stage (18) of the second microscope (36), and the second (36) microscope is calibrated using (36) a second microscope-dependent coordinate system, based on the second microscope (36). Next, the sample containing slide is mounted against the second stage (18). The stored feature location is read (3004) from the memory, and transformed (3006) from the microscope-independent coordinate system to the second microscope-dependent coordinate system. The transformed feature location in the second microscope-dependent coordinate system is utilized to relocate (3008) the feature on the sample containing slide.

Title: Two trip window cutting system
Inventor: BAILEY THOMAS F
IPC: E21B7/08
Filed: 1996-10-16
Abstract: A two trip sidetrack casing milling apparatus for elongating and enlarging a previously formed window in a cased borehole in preparation for a subsequent sidetracking drilling operation is disclosed. The apparatus consists of three mills on a shaft, a first window mill is secured to an end of a shaft. The first window mill forms a diameter larger than a diameter of a subsequent sidetracking drill bit that is passed through the window. A second pilot mill is secured to the shaft and strategically positioned above the first window mill. The second pilot mill forms a diameter that is less than the diameter of the first window mill. A third watermelon mill is secured to the shaft and strategically positioned above the second pilot mill. The third watermelon mill forms a diameter that is at least the same diameter as the first window mill.  The second, smaller in diameter pilot mill serves to move toward the window thereby straightening the shaft while further cutting a portion of the casing surrounding the window thus assuring a more stable and accurate sidetrack direction. The third watermelon mill serves to dress the window in the casing after the first window mill and the second pilot mill pass through the casing.
