Abstract: POLLUTANT ADSORPTION METHOD AND APPARATUS                    ABSTRACT OF THE DISCLOSURE           A method and apparatus for the removal of pollu-tants from flue gas includes a first adsorber spaced apart from a second adsorber and a flue gas cooling unit located intermediate the two adsorbers.  Flue gas is passed through the first adsorber at a preferred temperature range for the efficient adsorption of sulfur trioxide, is cooled by the cooling unit, and is passed through the second adsorber unit at a preferred temperature range for the efficient adsorption of sulfur dioxide and the oxides of nitrogen.  By efficiently removing sulfur trioxide in a first adsorber the acid dew point of the flue gas is lowered to a tempera-ture below the preferred temperature range for the efficient adsorption of the sulfur dioxide and the oxides of nitrogen. The threat of a corrosive acid attack is minimized while permitting the efficient adsorption of the sulfur dioxide and the oxides of nitrogen.

Title: Roof for covered electric smelting  furnaces
Inventor: KROGSRUD HARALD
IPC: F27D1/02
Filed: 1979-03-16
Granted: 1982-04-27
Abstract: ABSTRACT OF THE DISCLOSURE           An improvement in a roof for covered electric smelting furnaces is disclosed.  Cooling pipes are disposed on the outside surface of the roof sections and are of sufficient capacity and spacing to maintain a temperature on the inside of the roof of 150°C-400°C.  The cooling system of the invention maintains   the roof at an acceptable temperature during operation of the furnace and is designed so that there is a very small temperature gradient between the inlet and the outlet for the cooling fluid.  Thus the roof temperature will also be maintained in a relatively narrow temperature range during operation.

Abstract: ABSTRACT OF THE DISCLOSURE A tank for use with toilets which includes both an inlet duct and an overflow duct integrally formed in a wall of the tank and in which the mouth to the overflow duct is situated at a level below that of the upper end of the inlet duct.  The inlet duct terminates at its upper end in an inlet valve which includes a conical protuberance with a center bore.  A cap and seal centered on a stem which is received in the bore, act under the influence of a float to shut off water flow through the inlet duct.  The overflow duct intersects a passage through which flushing water is discharged from the tank into the toilet. The predetermined location of the mouth of the overflow duct below the level of the upper end of the inlet duct prevents siphon  back through the inlet duct, while at the same time allowing a proper level to be set for water in the tank.

Abstract: ULTRAHIGH RESOLUTION PHOTOCOMPOSITION SYSTEM    EMPLOYING ELECTRONIC CHARACTER GENERATION     FROM MAGNETICALLY STORED DATA                    ABSTRACT OF THE INVENTION A photocomposition system for composing type-face characters on a CRT display using a magnetic font disc formed of plural variable length character sectors wherein each sector includes successive storage cells containing all of the coded signals necessary to des-cribe a single character image which signals may be retrieved and decoded for use by the CRT to create an optical image of the character.  An optical scanner system is disclosed for optically determining the coordi-nate points on the boundary of an original character design for subsequent encoding into successive 3 bit binary codes representing successive end to end transla-tional movements along the boundaries of the character design being encoded.  The translational movements are selected from a subset of a total of 24 possible translational paths wherein the paths making up the subset is continually varying dependent on the general direction of the previous translational path.  An elec-tronic printer system is disclosed for retrieving a single groups of character identifying translational command codes in response to text composing signals produced on a text editor.  Each group of translational command codes is temporarily stored for decoding into coordi-nate signals used to access a high speed output memory having storage cells corresponding to the coordinates of the elemental areas (dots) on the CRT screen con-ceptually divided into an elemental area (dot) matrix. Following one complete decoding cycle, the data stored in the high speed output memory is used to cause the CRT to create an image of the character.

Abstract: APPARATUS AND METHOD FOR MEASURING   SCATTERING OF LIGHT IN PARTICLE          DETECTION SYSTEMS            ABSTRACT OF THE DISCLOSURE In an apparatus in which particles are passed through an optical sensing zone to measure their light scattering characteristics for the purpose of identifying the particles, means and a method are provided for deviating the collected light in accordance with predetermined different paths to a plurality of different photodetecting devices.  The deviation is effected simultaneously with collection by optical radiant energy reflecting means.  The different photodetecting devices enable the measurement of energy scattered along the particular path which is identified with that device.  The paths are established by the combined collecting and deviating means rather than permitted to evolve by the scattering phenomena themselves whereby the photodetecting devices can be located in convenient arrangements and may be conventional in construction.

Title: Physical modification of the viscosity characteristics of starchy flours
Inventor: TUSCHHOFF JOHN V
IPC: C08B30/12
Filed: 1980-04-23
Granted: 1982-11-16
Abstract: ABSTRACT A method of modifying the viscosity characteristic of a starchy flour by physical treatment, including beating in alcohol in a confined zone.  The resulting starchy flour exhibits thin-thick viscosity characteristics when beated,  and provides added viscosity in acid systems without breaking down.  It has particular application to baby food recipes to impart desired texture and mouthfeel.  Oat flour is the presently preferred starchy flour to be treated for use in baby foods.        In one embodiment, a starchy flour is slurried in aqueous organic liquid, preferably ethanol, and is then subjected to heat and pressure for a predetermined time to modify the physical properties of the flour.  The specific combination of pressure, temperature, and heating time determine the properties of the treated flour.  The alcohol treatment of the starchy flour may be performed continuously by forcing the starchy flour slurried in alcohol through a tubular confined zone under the required conditions of heat, pressure and residence time in the reactor to accomplish the desired physical changes.  The continuous process greatly improves production rates.
