Title: Enhanced combustion of hydrocarbonaceous burner fuels
Inventor: ARADI ALLEN A
IPC: C10L1/24
Filed: 1997-05-12
Abstract: A burner is operated by continuously feeding into its combustion zone while combustion is occurring therein, (a) a middle distillate burner fuel with which has been blended in any sequence or combination a minor combustion improving amount of fuel-soluble manganese polycarbonyl compound(s), and (b) a total amount of air above 100% of the stoichiometric amount required for complete combustion of all fuel being introduced into said zone but which is below 105% of such stoichiometric amount. Preferably at least alkali or alkaline earth metal-containing detergent and fuel-soluble dispersant have also been blended into the fuel being used. The efficiency of operation of blue and yellow burners is thereby improved, and emissions such as carbon monoxide and nitrogen oxide can be reduced as compared to operation of the same burner on the same unadditized base fuel.

Title: Method and apparatus for impregnating  a porous substrate with a solids-bearing saturant
Inventor: LONG ELIOT R
IPC: B29B15/10
Filed: 1997-06-24
Abstract: A method and apparatus for impregnating a porous substrate with a solids-bearing saturant first introduces the saturant into the substrate from a first side, and then introduces a displacement material into the substrate from the first side. This displacement material forces at least some of the saturant in the substrate farther into the substrate, away from the firstside. A wide variety of devices can be used for introducing the saturant and the displacement material into the substrate, including pressure saturators, converging chamber pressure saturators, roller coaters, blade coaters, and the like. By pushing the saturant away from the first side with the displacement material, the first side can be made more suitable for further processing such as adhesive bonding.

The liquid line carries lubricant or other liquid from the pump (e.g., air tool lubricator) to an air tool or other article. A priming pump is mounted on the body and is capable of delivering a predetermined amount of liquid from the reservoir to the liquid chamber.      The priming pump is used to fill the liquid line with liquid.

Title: Dual functioning seal for rock bits
Inventor: FANG ZHIGANG
IPC: F16J15/32
Filed: 1997-10-07
Abstract: Dual functioning seals for use in forming a lubricant seal in a rotary rock bit comprise an annular elastomeric seal body having a dynamic seal surface for sealing against a dynamic surface and a static seal surface for sealing against a static surface.  The seal body has an asymmetric axial cross-sectional geometry the dynamic seal surface having a greater radius of curvature than that of the static seal surface.   The dynamic and static seal surfaces are formed from different elastomeric materials, and the dynamic seal surface is formed from an elastomeric material that is harder and more wear resistant than the elastomeric material used to form the static seal surface.  A rotary rock bit seal constructed in this manner is well adapted to accommodate the different operating conditions and sealing requirements that exist both at the dynamic and static surfaces of the seal to ensure optimal seal performance and, thereby enhance the service life of the rock bit.

Patent CA-2223379-A1 (CA)
Inventor: FELDMAN ROBERT M
IPC: F16K35/06
Filed: 1997-12-03
Abstract: A valve assembly for inflatable bladders, including beds, balls, toys, and other inflatable objects includes a locking mechanism within the valve for releasably holding the valve opened.  The valve acts in three distinct ways.  In a first way the valve is closed maintaining the bladder internal pressure.  In a second way the valve may be incrementally opened by a user to release the internal pressure to suit the user. In a third way the valve may be opened and locked or latched to remain open allowing the deflation of the bladder.  A spring provides a return force to close the valve when the lock is not engaged.  Air pressure from outside the bladder supplied by a pump or the like will force the valve diaphragm open against the spring and allow air to enter.  The diaphragm is made of a resilient seal material.  The locking mechanism is engaged by pressing the diaphragm open and twisting to engage a lock.  When the lock is further twisted or twisted in the reverse direction the lock is disengaged allowing the spring and internal air pressure to close the valve.  The valve can be pressed from the exterior to open the valve, without engaging the lock, for a selectable time such that the pressure within the bladder can be adjusted.  Adapters may be used with the valve assembly so that different air blowers can be used to inflate the bladder.
Patent CA-2223812-A1 (CA)
Title: Method of creping tissue webs containing a softener using a closed creping pocket
Inventor: SCHROEDER WEN ZYO
IPC: D21H19/10
Filed: 1996-07-16
Abstract: The invention consists of soft, bulky tissue products that result from the presence of a debonder/softening agent in the outer layers of the tissue and creping under "closed" pocket conditions. The debonder/softening agents belong to a group of organic chemicals that include several imidazolinium quaternary compounds. These chemicals do not adversely interfere with adhesion, unlike most debonders, to the drying surface of the tissue machine. They can, therefore, be placed in the outer layers of the tissue that contact the dryer surface and improve creping. The tissue can then be creped off of the drying surface using a closed pocket, that is a pocket angle of less than 80 degrees. The closed pocket creping normally produces a thicker, less dense tissue but with coarse crepe. Closed pocket creping and the presence of most debonders in the dryer side layers would be expected to also produce coarse crepe structures. However, the interaction of debonder adhesive properties and the closed pocket creping conditions produces a bulky tissue with sufficiently fine crepe structure that results in high overall softness.

Title: Antenna having double-sided printed circuit board with colinear, alternating and opposing radiating elements and microstrip transmission lines
Inventor: BRENNAN MICHAEL L
IPC: H01Q21/10
Filed: 1998-01-21
Abstract: The present invention provides a microstrip collinear antenna having cable connector assembly means and a collinear microstrip printed circuit board means.  The cable connector assembly means responds to a radio signal, for providing a cable connector assembly radio signal.  The collinear microstrip printed circuit board means responds to the cable connector assembly radio signal, for providing a collinear microstrip printed circuit board radio signal.  The microstrip line collinear antenna is constructed with a number of one half .lambda. printed circuit board elements on both sides of a double-sided board.  These one half .lambda. sections are the radiators.  On the other side of the board opposite each radiator is a respective section of corresponding microstrip transmission lines to provide radio frequency power to each radiating element.  The microstrip line collinear antenna has the following advantages over the prior art antennas: it achieves shorter length due to close physical spacing of radiators, it maintains consistent pattern and impedance performance across the operating frequency range, it allows for accurate and consistent manufacturing through the use of advanced printed circuit board materials, allows for center feed design to achieve high-gain broadband operation, and it allows cost reduction with printed circuit board materials.
