Patent BE-796755-A (BE)
Title: Blast furnace control - by recording fluctuations of blast pressure and/or charge descent rate
Inventor: YOSHIKI M
IPC: C21B5/00
Filed: 1973-03-14
Abstract: The operation of a blast furance can be optimised by a system which assesses and controls the state of the furnace. The criterion for this assessment is either the fluctuation of the blast pressure within a predetermined interval or the fluctuation of the rate of descent of the charge within a predetermined interval both expressed in digital terms. Formulae are given to express both parameters as a pressure index or a descent rate index.

Title: Quadrilateral shaped wooden flooring blocks - are cut in planes of between 45 and 90 degrees w.r.t.
IPC: E04F15/04
Filed: 1982-10-01
Abstract: Wooden flooring blocks are cut in parallel planes making an angle of 45 to 90 degrees w.r.t. the axis of the tree trunk. The resulting blocks retain traditional hardwearing properties but have improved response to changes in humidity. The plane in which the wood grain lies causes the blocks to swell towards the free surface and not towards one another which would otherwise affect the stability of the flooring configuration.

Abstract: SULFONATION PARAMETERS USEFUL IN DESIGNING MICELLAR     DISPERSIONS USEFUL IN OIL RECOVERY PROCESSES                 ABSTRACT OF THE DISCLOSURE   A method of designing a micellar dispersion useful for oil recovery purposes is obtained by first establishing a lineal relationship between the aliphatic to aromatic proton (A/AP) ratio of the hydrocarbon portion of particular average equivalent weight petroleum sulfonates vs. the concentration of particular cosurfactants useful to stabilize the micellar dispersion, then using this relationship to design micellar dispersions.  Petroleum sulfonates useful in the dispersions are those having average equivalent weights of 350-525 and which have A/AP ratios within the range of 4-20 moles per mole.  Knowing the particular equivalent weight and A/AP ratio of the petroleum sulfonate, a cosurractant can be chosen or vice versa.  Preferably, the linear relationship is a semi-logarithmic plot.

Abstract: ABSTRACT OF THE DISCLOSURE        Apparatus for combining positional data from OMEGA and VOR/DME radio navigation systems to provide computed positional date corresponding thereto includes a circuit for generating an OMEGA compensation in accordance with the difference between the computed value of the positional data and the VOR/DME value thereof.  The computed value is provided by algebraically adding the OMEGA compensation to the positional data from the OMEGA system.  The gain of the OMEGA compensation circuit is adjusted in an inverse relation with respect to the range of the aircraft from the VOR/DME station thus providing high accuracy positional data throughout the enroute flight of the aircraft without the attendant complexities and inaccuracies normally associated with the separate OMEGA and VOR/DME radio navigation aids.

Abstract: COMPACT CRANE          ABSTRACT OF THE DISCLOSURE   A compact truck-mounted towing crane is constructed with a boom pivoted near the center thereof.  A tow bar secured at the rear end of the boom is positioned below the boom pivot, and a power cylinder is connected to the forward end of the boom for raising a vehicle which is to be towed.          The boom pivot is at the rear of a base secured to the frame of the towing vehicle and the power cylinder is secured to the front of the base.  The relative positions of the boom and power cylinder are such that the power cylinder arm is retracted during the power stroke to lower the front end of the boom, thereby raising the tow bar and the load thereon.         The tow bar together with the portion of the boom to the rear of the main pivot are removable as a unit by simply withdrawing a pivot pin which connects front and rear sections of the boom together in the vicinity of the main pivot.  The rear section is movable about this pivot pin between an extended or working position and a storage position wherein the tow bar is positioned above and to the rear of the main pivot.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a settling tank adapted for low-turbulence settling of solids such as fine silt and clay from water.  By the use of a continuous process involving con-tinuous removal of settled solids, it is possible to dispose of the solids through a system of re-inserting the solids into the extracted tar sands, from whence the tar sands loaded with the silt can be returned to the excavation site.  This permits the continuous settling of clay water, removal of settled clay slurry, and re-insertion of the clay slurry into the extracted tar sands.          Continuous operation also makes possible recycling the water from extraction discharge back into the extraction step; avoids discharge of the effluent containing oil emulsions, finely divided clay and other pollutant into our water courses, and avoids the necessity for large storage ponds for the treatment of such water to enable it to be returned to a water course.  The specification discloses a system comprising a circular tank for retention of water during settling, a radial boom provided at the level of the surface of the water for rotation around a central hub, means for rotating the boom, said boom having a leading edge and a trailing edge, said leading edge having a horizontal forwardly projecting shelf below the level of the water, said trailing edge having a horizontal rearwardly project-ing shelf also below the level of the water, said leading edge shelf, trailing edge shelf and boom bottom presenting a smooth continuous surface for non-turbulent passage through the water, said trailing edge having a means for uniform and non-turbulent supply of solids-containing water to the length of the shelf at a volume rate equal to the rate of horizontal displacement of the forwardly moving boom, said leading edge having a means for - a -ABSTRACT OF THE DISCLOSURE - Cont'd.   uniform and non-turbulent removal of cleared water from the length of the shelf at a rate equal to the displacement of the forwardly moving boom.                             - b -

Abstract: DUAL PICK-UP IGNITION SYSTEM WITH AUTOMATIC TRANSFER BETWEEN PICK-UPS           ABSTRACT OF THE DISCLOSURE         An ignition system for an internal combustion engine comprises a distributor containing a pair of magnetic pick-up devices each of which generates signals at a frequency representa-tive of engine speed. One pick-up is used normally during start-ing of the engine to fire the engine spark plugs and the other pick-up during running.  An automatic transfer circuit is pro-vided to transfer control from the first, or start, pick-up to the second, or run, pick-up when the engine begins to run under its own power and accelerate from cranking speed.   Should a condition occur indicative of a lack of signals from the run pick-up above a predetermined minimum frequency, the transfer circuit transfers control of ignition firing back to the start pick-up.

Abstract: ABSTRACT OF THE DISCLOSURE       A night visual aircraft system receives flight data from an aircraft simulator, and terrain data from the gaming area data base.  A computer within the night visual system organizes this image data by frame in a buffer memory according to a particular format of addresses, sequences, and bit places.  The following types of image data are uniquely positioned in the format:           A position vector (Vp), defining the changing posi-tion of the aircraft with respect to the terrain data origin.       Rotational matrix data defining the changing attitude of the aircraft with respect to the axes of the terrain coordin-ate system.           Initialization vectors (Vi), defining the position of certain landmark terrain lights with respect to the origin of the terrain data.           Delta data, defining the position of other lights with respect to the landmark lights.           String data, defining the spacing, color, intensity, and number of lights in a string of lights having equal spacing and intensity.           CIF data, defining the color, intensity, and defocus of individual lights.           Transfer data which is coded to identify the type of the subsequent data.     An image processor receives the formatted image data and translates delta data into a light source vector (Vls) defining the position relationship between each light source and the air-craft; rotates the Vls into channel vectors (Vc) according to the window orientation and the attitude (pitch, yaw and roll) of the aircraft; and projects each three-dimensional Vc into a two-dimension display vector (Vd).  An image generator receives the Vd and other image data to provide analog inputs to a CRT device which provides a window display in the simulated aircraft.
