Title: Character presence processor

Granted: 1981-12-15
Abstract: CHARACTER PRESENCE PROCESSOR                 ABSTRACT OF THE DISCLOSURE          A method and system for automatic optical character recognition wherein a continuous flow of image data is processed at a high scan rate. A two dimensional array of self scanning photo sensors is disposed to read characters located on a writing medium. Analog outputs of the cells of the photo sensor array are converted to a continuous flow of binary signals representing character segments or the absence thereof. Feature codes are generated in a ROM to produce a multi-bit feature code characterizing unique relationships between character segments. For each row and column scanned, a representative feature code is produced with a sequence of such codes representing a complete scan of the array. The features codes are received by a decision network as they are generated by the ROM. The decision network is provided with a multiplicity of nodes, each node being accessible to every other node by a one state change to produce a representative output character code. The multiple character codes which are produced during the movement of a single character across the sensor array are processed by a decision circuit which generates a final character recognition signal. A character presence processor searches for a vertical path between character segments to indicate the presence of a character by locating the beginnings and endings of characters. For certain unique characters having vertical gaps between portions of the character a means is provided within the character presence unit to indicate that the vertical gap is to be ignored and that a character code is not to be transferred to the decision circuit.

Abstract: METHOD OF DRYING GYPSUM WALLBOARD AND APPARATUS THEREFOR ABSTRACT OF THE DISCLOSURE The air flow in one zone of a gypsum wallboard dryer involves removal of the air from the wallboard drying section at one end of the elongate wallboard drying section, followed by directing a major portion of this air through fans to accelerate the air flow, next heating the air in an elongate plenum, through which the air passes, by directing high intensity flame angularly into the air flow from the periphery of the elongate section, thus creating agitation within the air flow to create uniformity of temperature therethroughout prior to directing the heated, thoroughly mixed air back into the wallboard drying section, at an end of the section opposite to the end from which it was originally removed.

Abstract: ABSTRACT OF DISCLOSURE     A method and apparatus for measuring the viscoelastic characteristics of a sample of a viscous liquid or gel contained within a closed can or other cylindrical vessel.  The can and sample are subjected to torsional oscillation about a vertical axis by an oscillation source through an elastic coupling member, the oscillation source operating either (i) at a fixed, predetermined frequency or (ii) at the resonant frequency of the can and sample.  Measurements are made of the amplitude of oscillation of the can and sample and of either (i) the angular phase difference between the oscillation of the can and sample and those of the source or (ii) the resonant frequency of the can and sample.          The measured data may be used either to compare the sample with a standard material or to calculate viscoe-lastic moduli of the sample.

Abstract: ABSTRACT OF THE DISCLOSURE           A process is provided for minimizing the deposition of materials like naphthalene and tar in the ammonia liquor coolers of the primary cooler in a by-product recovery process for coking carbonaceous materials.  The am-monia liquor coming from the primary cooler, wherein it is used to cool the coke oven gas, has added to it light oil before it reaches the ammonia liquor coolers, where it is cooled indirectly with water.  The addition of the light oil keeps the naphthalene and tar in solution at the lower temperatures of the ammonia liquor coolers, thereby reducing or preventing the deposition of the naphthalene and tar in the ammonia liquor coolers.

Title: Devices adapted to detect variations in  magnetic flux notably circuit breakers

IPC: G01R15/18
Filed: 1979-07-17
Granted: 1982-09-14
Abstract: ABSTRACT OF THE DISCLOSURE The device detects variations in magnetic flux so that the passage through a given threshold by the amplitude of such a variation per unit time is manifested by the movement of an element adapted to trigger an action. It comprises a practically closed electrical circuit, such as a winding, ar-ranged and mounted so that the variation in a magnetic flux to be detected generates by induction at the terminals of this winding an electrical volt-age V, two electrodes forming a capacitor, one of which is movable with re-spect to the other, an electret interposed between these two electrodes and whose charge produces a field exerting on these electrodes an electrostatic force H tending to bring them mutually together, means for forming a recti-fied voltage U from said voltage V and for applying this voltage U between the two electrodes in a direction such that the field which results there-from is opposite that generated by the electret and hence tends to reduce the force H, and means urging the movable electrode scarcely reversibly in the opposite direction to the force H.  The force G of these urging means and the charge of the electret are selected so that the overshoots by the voltage U of a predetermined threshold Uo corresponding to the level to be detected of the magnetic flux-generating phenomenon cause swings of the mov-able electrode from its vigilance position to its active position, the triggering of said action being servocoupled to said swings.

Granted: 1982-05-18
Abstract: ABSTRACT OF THE DISCLOSURE The use of polyisocyanates as binders in the preparation of particle boards is subject to the drawback that the boards exhibit a tendency to adhere to the face of the platens used in their formation. This problem is minimized by incorporating minor amounts of a mixture of certain mono- and di- (saturated or unsaturated aliphatic or aromatic) acid phosphates or the corresponding pyrophosphates, into the polyisocyanate to be used as binder.  The polyisocyanates and the acid phosphates and or pyrophosphates, are applied to the particles separately, or after preblending one with the other.  Whether the components are applied separately or in combination one with the other, they can each be applied either neat or in the form of an emulsion or emulsions.
