Abstract: APPLICATION OF GUS DEMITRIOS KERITSIS FOR UNITED STATES PATENT ON     TOBACCO TREATMENT       (PM 808) Abstract A process for maximizing reduction of gas phase components during combustion of tobacco products is disclosed. The process comprises contacting tobacco material with an aqueous solution to form a tobacco extract. After separating the extract from the fibrous tobacco portion, the extract is treated to remove potassium nitrate by ion exchange, electro-dialysis, crystallization techniques or the like. Thereafter, potassium ions in the form of a potassium salt other than potassium nitrate are restored to the potassium depleted tobacco and/or extract to a level approximating that originally present in the tobacco prior to extraction.

Abstract: BAND AND HAMMER DOT MATRIX PRINTER           Abstract Described, is a printing mechanism allowing full exploitation of the potential of dot matrix printing. Dot forming elements are mounted on a carrier for transport past an array of hammers located in front of media to be marked upon.  The dots or carrier are im-pacted by the hammers to form dots on the medium.  By appropriate control of motion of the printing medium and timing of the hammer impacts, a dot may be formed anywhere on the surface of the medium.  This allows un-limited character font set generation as well as special character printing for enlarged font, miniaturized font, fast rough draft copy printing, the printing of ascenders and decenders for characters and for condensed or compacted printing.  In addition, the mechanism permits an all points available graphics generation system and full control for variable vertical spacing of printed elements and of variable horizontal spacing of the printed elements.  Variable print element shapes, grey tone graphics printing and multi-color additive or subtractive color processes are also facilitated.

Abstract: Abstract of the Disclosure Electronic engine synchronization and timing appar-atus for use in controlling fuel injection and/or spark ignition for an internal combustion engine is disclosed.          An engine crankshaft rotates a rotary body having a plurality of radial projections, and a single crankshaft reluctance sensor is utilized to provide pulses in response-to the passage of these projections and thereby provide a signal related to crankshaft position.  An engine camshaft rotates a rotary body with radial pro-jections at half of the crankshaft speed, and a pair of camshaft sensors provide signals in response to the passage of the camshaft projections which are indicative of the rotational position of the camshaft.  The signals provided by the crankshaft and camshaft sensors are received by circuitry which provides a crankshaft refer-ence signal having transitions of alternate predetermined polarities at specific rotational positions of the crank-shaft and also provides cylinder identification signals which are indicative of the angular rotational position of the camshaft rotary body.  These signals are then utilized by conventional electronic fuel injection and/or spark ignition control apparatus to control engine cylinder operations in the proper sequence and at the proper time.

Abstract: ABSTRACT           The invention is concerned with a device and method for converting at least a part of a stream of a flowable medium flowing down a tube into a flat stream having a substantially uniform flow rate across its width.  The device comprises a substantially vertical tube down and through which the medium can flow; a stationary and planar first plate, the first plate being substantially flat and substantially horizontal to induce smooth and non-turbulent flow of the medium across the first plate and being disposed below the tube; and at least one second plate inclined at an angle substantially less than 90° relative to the first plate and adapted to receive medium flowing over the edge of at least a portion of the first plate and extending at least partially beneath the first plate and terminating in a straight lower edge. Means are also provided to meter the amount of medium flowing onto any one increment of the width of the second plate so that it will be, after flowing down the second plate a predetermined distance, substantially equal to the amount of medium flowing down any other increment of equal width.  The invention is particularly useful in handling slurries or dispersions of solid or liquid particles in a liquid.

Abstract: ABSTRACT     Cutting elements, for example of polycrystalline sintered diamond, the cutting faces of which are set differently to the cutting direction, are disposed on a rotary drill bit.  One group of cutting elements has its cutting faces substantially perpendicular to the cutting direction (straight set cutting elements) while other groups of cutting elements are at an acute angle to the cutting direction (obliquely set cutting elements).          Because of their greater pressure per unit area, the obliquely set cutting elements penetrate more easily into plastic formations and can tear these up.  The straight set cutting elements, which do not develop a great pressure per unit area, but work over a wider range, can better pare off the formation prepared by the obliquely set cutting elements.

The beam may be spatially scanned across the material to create a matrix of holes representing stored information.  Using a storage material which is responsive to an electric field for frequency shifting the holes in the material, holes at different frequencies are created or detected in a material by a beam of frequency f by scanning the magnitude of the electric field thereby shifting the holes created away from the frequency f or shifting the holes to be detected through the frequency f.  This electric field may be applied by a controlled voltage source connected to transparent conductive electrodes on the surfaces of the storage material.

Abstract: VENTURI BURNER NOZZLE FOR PULVERIZED COAL                     Abstract of the Disclosure A new and improved nozzle for pulverized coal comprises a tubular nozzle having an inlet for receiving a primary, flowing stream of coal/air mix-ture and an outlet for discharging the stream into a furnace. A venturi-like, flow constrictor is coaxially disposed in the nozzle adjacent the outlet end with a divergent flow section terminating at a maximum diameter adjacent the outlet end of the nozzle in the furnace.  A convergent venturi section is mounted upstream for concentrating the pulverized coal toward the central portion of the flowing stream and a flow spreader is mounted in coaxial alignment in the diver-gent flow section of the venturi and includes a maximum diameter, open end adjacent the outlet end of the nozzle . Wall surf aces of the spreader cooperate with those of the divergent flow section to form an annular pattern of discharge from the outlet end of the nozzle.       A stream of secondary air is introduced to flow in a rapidly swirling annular pattern around the discharge from the nozzle, and by properly matching the secondary air velocity to that of the primary air/coal discharge velocity, the flame is increased in length and an outer, torroidal recirculation zone is formed around the outside of the coal/air discharge pattern. An inner, recirculation zone is created adjacent the large open end of the flow spreader inside the primary air/coal discharge pattern. A plurality of swirl vanes are provided between the outer surface of the spreader and the adjacent facing surface of the diver-gent flow section for imparting a swirling action for stabilizing the annular discharge pattern of the pri-mary coal/air stream from the conduit into the furnace.       This stabilized discharge pattern forms a wall or shield from the secondary air to provide a high tem-perature, reducing stagnant area adjacent the open end of the flow spreader. The inner and outer recir-culation zones draw a portion of the hot combustion products back toward the open end of the flow spreader and volatiles in the coal are driven off rapidly in this high temperature, reducing atmosphere, minimizing the formation of NOX.
