Title: Gasifier apparatus
Inventor: MAYER EDWARD F
IPC: C10J3/20
Filed: 1988-08-04
Granted: 1991-03-19
Abstract: GASIFIER APPARATUS                   ABSTRACT OF THE DISCLOSURE       A  gasifier   for  converting   solid  organic  fuels  to combustible gas includes a cylindrical body having insulated side walls and a gas outlet port near its base.  Affixed to the top of the cylindrical  tank is  a conical-shaped  fuel feed  hopper and beneath it  and within  the interior  of the  tank is an inverted truncated cone.  Positioned  beneath the  throat of  the inverted cone is  a pyramidal-shaped  grate for  supporting the combusting solid fuel during the inversion process.  Positioned  beneath the grate are  a series of baffles.   Combustion  air  is  drawn  in through  the  upper  portion  of the  tank near  the base  of the frusto-conical feed  hopper by  the action  of a motor-driven fan coupled to the gasifier's outlet port.  The  down draft  gas flow reduces noxious  fumes  and  pollutants  while  the  baffles,  by increasing the fluid  velocity of  the gases,  tends to  make the unit self-cleaning.  The design of the hearth cone and grate also eliminates bridging of the fuel during the gasification process.

Title: Bidirectional control signalling bus interface apparatus for transmitting signals between two bus systems
Inventor: BARLOW GEORGE J
IPC: G06F13/40
Filed: 1988-10-27
Granted: 1993-09-07
Abstract: ABSTRACT OF THE DISCLOSURE     A synchronizing apparatus couples two independently operated bus  systems,  each bus  system capable of generating asynchronous control signals for controlling the states  of  all  of the units within the entire system.  The apparatus includes a pair of synchronizer storage elements, each connected to receive, store, and transmit an asynchronous control signal from one of the bus systems to the other bus system.  The synchronizer elements  are  connected  to  receive  a  set  of complementary clocking signals from a timing source. Both synchronizer elements are interconnected so that by decoding the internal states of such elements only a one of the control signals will be transmitted when both  synchronizer  elements  simultaneously  receive control  signals  from  both  buses  thereby ensuring reliable operation throughout the entire system.

Title: Color correction for video graphics system
Inventor: GRUTERS MICHAEL S
IPC: H04N9/74
Filed: 1988-11-24
Granted: 1994-10-11
Abstract: Abstract of the Disclosure A color correction method for a video graphics system defines a region of color space within which target objects to be corrected lie.   The region is defined automatically by positioning a target box within a representative portion of a target object within a video picture and computing from the pixels within the target box a range of color parameters which include the target object.  A desired color for the target object is selected, and all pixels which are both within the video picture or a selected portion thereof and also within the defined region of color space are changed accordingly.  Anti-aliasing is provided by scanning an area surrounding each pixel to determine the number pixels within the area which are within the defined region, and changing the color of each pixel according to the ratio of the number of pixels which lie within the defined region and the total number of pixels within the area.

Abstract: ABSTRACT OF THE DISCLOSURE          An outlet valve assembly is provided for a railway tank car.  The valve is mounted at the bottom of the tank car for discharging downwardly between the tracks.  The valve is operable between the closed position to occlude flow through the valve and an opened position to permit flow through the valve.  A shaft is operably connected to, and extends from, the valve on a horizontal axis normal to the length of the tank car for being rotated on the axis to operate the valve between the closed and opened positions.  A handle is connected to the shaft at a predetermined distance from the valve, and the handle extends generally radially outwardly from the shaft. The valve is operated between the closed and opened positions when the handle is swung through an arc from an initial orientation to a final orientation.    The length of the handle and the predetermined distance between the valve and handle connection is selected such that the handle can be swung between the initial and final orientations by a person standing upright beside the tank car outside of the tracks.

Abstract: A percussive-action mole (10) is energised by compressed air supplied through hollow rods (36) in a string (12) connected to the mole.  A hydraulic motor (18) rotates the string and mole. The mole head  (30)  has a slant face (32)  and a transverse permanent magnet (34).   After each new rod is added to the string, the air supply to the mole is stopped to halt the mole which continues to be rotated.  The field fluctuations from the magnet are detected by a magnetometer (24) using its probe at three positions (50), (52), (54) determined by a triangular frame (22) placed flat on the ground.  Calculations using the three readings each representing the distance of the magnet from the respective position on the frame enable the position and depth of the magnet to be determined.  After completion, the passage (38) can be reamed to larger diameter to receive a gas pipe or other service.

Abstract: PLASMA GENERATING APPARATUS AND METHOD         ABSTRACT OF THE DISCLOSURE The plasma generating apparatus and method of this invention is particularly, although not exclusively, suitable for plasma spraying. The plasma spray apparatus and method of this invention generates a free-standing electromagnetically coalesced stable plasma through which feedstock may be fed, eliminating problems with conventional radial feed plasma guns. The plasma spray apparatus of this invention includes a plurality of pilot plasma guns preferably angularly displaced symmetrically about a common axis and a main transfer electrode located downstream of the pilot plasma guns having a nozzle bore coaxially aligned with the common axis. The plasmas generated by the pilot plasma guns are directed into the throat of the main transfer electrode bore and a second plasma gas is supplied to the throat of the main transfer electrode bore which is ionized and coalesced with the plasmas generated by the pilot plasma guns, generating a free-standing electromagnetically coalesced plasma. The second plasma gas may be a conventional inert or unreactive plasma gas or more preferably a reactive plasma gas increasing the energy of the free-standing plasma and providing additional advantages. The feedstock may then be fed through the bore of the transfer electrode and the free-standing electromagnetically coalesced plasma, uniformly heating the feedstock and permitting the use of a wide range of feedstock material forms and types, including particulate feedstock having dissimilar particle sizes and densities, slurries, sol-gel fluids and solutions.

Abstract: In radio communications receivers for use on frequency hopping radio communications networks, the received signal in each hop period is analyzed and assigned a quality value. If more than one signal is present during the hop period it is determined that more than one network has changed to the same frequency. Similarly if the received signal is out of synchronism it is determined that more than one network has changed to the same frequency. When more than one network has changed to the same frequency, the received signal is not output by the receiver but is replaced by an earlier (or later) received signal.

The temperature is recorded simultaneously by two temperature responsive means, one of which is placed in the center of the sample and the other in the immediate vicinity of the vessel wall. The dispersion degree of the graphite phase is assessed in relation to known reference values by aid of recorded values of supercooling at the vessel wall, the recalescence at the vessel wall, the difference between the temperature at the vessel wall and at the centrum of the vessel and the derivative of the temperature decrease at the vessel wall during the time of constant eutectic growth temperature at the center. When necessary a graphite nucleating agent is added to the molten bath or the dispersion is lowered by implementing a holding time prior to casting. The morphology of the graphite precipitation is also determined by aid of recorded values and possibly corrected by changing the amount of structure-modifying agents present.
