Abstract: ABSTRACT An optimal parametric signal processor, which receives auto-correlation and cross-correlation coefficients of a system under study, provides predictor and filter coefficients of the system in an optimal manner, and allows the use of any number of available parallel pro-cessing units. The signal processor may be implemented in a fully parallel or fully sequential manner, or in a "parallel-partitioned" im-plementation which provides the benefits of parallel processing, manage-able hardware complexity, and optimal signal processing for a given number of available processors.

Abstract: RD-15,727 LIGHT BLOCKING AND CELL SPACING STRUCTURE FOR        LIQUID CRYSTAL MATRIX DISPLAYS                 Abstract of the Disclosure Light blocking spacer material is disposed so as to at least partially cover the data and/or gate lines in a variety of liquid crystal display (LCD) devices. The material prevents spurious visual information from being displayed as a result of high RMS supply voltages applied to the data lines, such voltages acting to switch liquid crystal material at inopportune times and to thus degrade the displayed image.  The light block-ing material also enhances the displayed image by acting as a spacer between the front and back LCD device panels to insure uniform cell spacing.  Light blocking material is also employed at the same time to prevent light from reaching light sensitive thin film field effect transistors (FETs) which operate to switch each cell or to establish gray levels therein.  The light otherwise has a tendency to discharge the LCD cell, also hampering device function.

Abstract: Endomycorrhizal inoculants for leafy plants are formed from sclerotia-producing fungi such as Cenococcum geophilium.  Living mycelia are developed in darkness for about 3 months at about room temperature under substantially anaerobic conditions by contact with a particulate inert support such as perlite in a liquid growth medium for the fungus.  When seeds of woody plants such as pine and of herbaceous plants such as corn, wheat, onion and asparagus are inoculated and grown on the inoculants, endomycorrhizal infection in leafy plant roots is induced.

Abstract: Disclosed is apparatus for carrying a propane tank and the carrier has a pivotal handle which pivots up over the top of the tank once the tank has been fitted into the apparatus.  When the top pivotal handle of the apparatus is used, the handle will naturally come close against the user's side and the propane tank (and the base of the tank) will travel in a relatively vertical position due to gravity, thus leaving the user's arm in a more natural position and at the same time keeping the tank and carrier from rubbing against the user's leg with undue friction.          The apparatus has two side mounted handles which permit the user to lift the tank (and carrier) more easily in and out of a vehicle or in and out from under the barbecue cart where tanks are normally positioned.  The apparatus also has a base which is larger than the largest diameter of the propane tank and accordingly the tank becomes more stable when positioned in the apparatus.

Screens surround the augers except at the ends of the augers to allow grain to enter and leave at the ends of the augers. A box like frame encloses the rearward ends of the augers with an open top to allow grain to be be cleaned to be dumped into the open rear ends of the augers. A motor is provided with drive means to rotate the augers simultaneously whereby the augers will auger the grain from the box along the augers within the screens to the forward end of the frame, a chute is provided at the forward end for the grain to leave the frame after traveling along the augers. The mesh of the screens is smaller than the grain so as to retain the grain within the screens as it travels along. The mesh allows foreign particles and chaff smaller than the size of the openings to pass through the openings and drop downward from the screens. A bin is provided beneath the screened augers to collect the smaller particles and another auger is provided in the bin to auger the particles out of the bin.

Abstract: ABSTRACT OF THE DISCLOSURE:         The solutions are concentrated by multiple-effect evaporation in indirectly heated evaporators.  The highest concentration of the solution is reached in a final evaporator stage, which is heated with live steam.  The final evaporator stage consists of two to four falling-film evaporators, all of which are heated with live steam.  The falling-film evaporators are consecutively flown through by the solution.  Vapor is withdrawn from that falling-film evaporator which is the first to be supplied with the solution and at least part of said vapor is directly contacted with the solution as it flows down through the heating zone of at least one other evaporator of the final stage.  From that falling-film evaporator of the final stage which is the first to be supplied with the solution the vapor may be fed to all other evaporators of the final stage.

Abstract: Method of utilizing process gas containing sulphur dioxide obtained from discontinuous processes, in the manufacture of sulphuric acid in a contact plant. When practicing the method according to the invention, all of the process gas, or a predetermined amount thereof, is withdrawn from the process during process operational periods, in which gas containing sulphur dioxide is generated, and the sulphur dioxide contained by the withdrawn gas is at least partially separated therefrom to form a liquid phase containing the amount of sulphur dioxide separated. The gas partially freed from sulphur dioxide, together with any non-withdrawn process gas, is passed to the contact plant for manufacturing sulphuric acid. Stored absorption liquid is utilized during those periods in which no process gases are produced or passed to the contact plant or in which the process gases contain insufficient sulphur dioxide. Sulphur dioxide is stripped from the liquid phase with the aid of a carrier gas, and the carrier gas, together with the stripped sulphur dioxide, is passed to the contact plant. This enables a required amount of gas and sulphur dioxide to be constantly supplied to the contact plant, even during those periods when the discontinuous process does not produce a sulphur-dioxide-containing gas or produce a gas having an insufficiently high sulphur-dioxide amount.
