Abstract: ABSTRACT OF THE DISCLOSURE     The apparatus includes a plurality of extruders which feed parallel streams or ribbons of raw material or charge along rollers through successive chambers in a kiln and through an annealing lehr to zones where the material is cut.  The surfaces of the raw material are coated on three sides with a parting or releasing agent and, on the side to be exposed, with a glaze or engobe, or left uncoated.  The firing chamber of the kiln has opposed rows of fuel burners on the sides directed toward ports on the other side and refractory rollers which protrude through the side walls and are supported on circumferentially spaced wheels.  Wheels between adjacent ends synchronize rotation of the rollers.  Manifolds feed the stack gases from the firing chamber into the preheating chamber.  The process includes using charges which are either a mixture of a small amount of soluble carbonaceous material and water to adjust the carbon and moisture content of the clay or silica with carbonaceous material and water.  If the charge is clay, it is then extruded as ribbons, coated with releasing agent and glaze or engobe, then dried, preheated, sintered, fired at above about 2000°F and annealed.  Cellulated vitreous clay product results which is cut into rectangular blocks.  If the charge is silica, no annealing is required and normally a glaze formed by silica sand may be applied to a surface thereof.  The silica charge is produced by pressing simultaneously the silica charge and a material to form a plate rather than being extruded, successive plates being passed through the kiln to cellulate and vetrify.      Consumable, sectional trays are also disclosed.

Abstract: ENVIRONMENTALLY SAFE PROCESS FOR DISPOSING OF              TOXIC INORGANIC CN-CONTAINING SLUDGE                           (D# 76,075-F) ABSTRACT OF THE DISCLOSURE        Toxic inorganic CN-containing sludge as produced by treating at least a portion of the water used to quench cool and/or scrub the hot raw effluent gas stream from a partial oxidation gasifier with a ferrous salt and a base may be disposed of by separating the inorganic CN-containing sludge from the water and introducing the sludge into the partial oxidation gas generator in admixture with the hydrocarbonaceous fuel feed.  Most of the cyanides are effectively destroyed in the reaction zone, and the ash components in the waste solids are recovered as slag from the generator.  The separated water is upgraded by further treatment and recycled to the quench tank and/or gas scrubber.  The subject process provides an environmentally safe solution for the otherwise costly problem of disposing of toxic sludge.  When coal is included in the feed to the gas generator, any calcium in the sludge will act as a fluxing agent for the coal ash.  A more fluid slag having a lower ash-fusion temperature is obtained. Because the partial oxidation gasifier may be run at a lower temperature while still producing molten slag, oxygen requirements may be reduced.     ptn627                  -I-

Abstract: Relative Humidity or Water Activity Apparatus Anthony Nelson Sharpe, 230 Christian St.                  Almonte,  Ontario K0A lA0, Canada ABSTRACT An apparatus for measuring relative humidity or the water activity level in a food sample, within defined limits, gives a reading within seconds.  The apparatus comprises a rough or porous display surface to which is applied a pattern of graded indicator substances, each of which deliquesces at a known relative humidity.  Said indicator substances are applied in such quantity that they are invisible or nearly so when dry, but become severally or wholly visible again on exposure to a moist atmosphere, according to the relative humidity of the atmosphere in relation to the range of relative humidities covered by said deliquescent indicators.  If said indicators are applied in the form of the decimal fractions corresponding to their relative humidity values the apparatus provides a digital readout of relative humidity, directly and without electronics.  In a modification the display surface is of glass treated with dichlorodimethylsilane after the indicators have been applied.  In another the display surface is a thin porous polymer film.  In further modifications the display is enclosed in a shallow dish which may be applied to the surface of a food, or in a spearlike container which may be plunged inside a food.          In a final modification the deliquescent indicators are mixed with a dye which diffuses into a removable porous layer to provide a permanent record of the humidity or water activity.
