Abstract: Title:         "Material Dispensing Machine"     ABSTRACT A machine for dispensing dry and moist materials including those which are self-adhering and/or compactible or which tend to agglomerate comprising a material dispensing chute formed at its sides by horizontally reciprocating, expanded metal grid plates which engage and separate material from adjacent material pressing thereagainst for passage through the grids of the plates and metered depositation onto articles or products passing therebeneath. The grid plates have horizontally spaced, downwardly converging upper portions forming a V where the majority of material is separated and horizontally spaced, parallel lower portions forming a narrow transverse width channel which prevents material from loading up between the grid plates in the V', such giving the chute a generally Y-shape in transverse cross-section. Depending on the material being dispensed, the grid plates may be formed from either flat or raised expanded metal grid material preferably having a diamond grid pattern that enhances material separation through a funneling or wedging effect. The grid plates are desirably reciprocated in respective top and bottom tracks by eccentrics in a direction opposite each other for more uniform discharge of material. Either grid plate may be fixed and/or replaced by a solid or part solid/part grid plate, the latter providing a narrower width discharge pattern. Also provided is a power drive motor mount which permits quick and easy removal of the motor to allow cleaning of the machine without subjecting the motor to the cleaning environment.

Abstract: LOSS MINIMIZATION COMBUSTION CONTROL SYSTEM                     ABSTRACT OF THE DISCLOSURE            A system for minimizing combustion operation losses includes measuring a load index for the combustion operation which is proportional to the fuel demand or the output thereof, measuring an amount proportional to the air heating losses of the combustion operation and measuring an amount which is propor-tional to the fuel loss of the operation.  The air heating loss is measured by multiplying a flue temperature by an amount of unburned oxygen in the flue gas.  This quantity is multiplied by a cost factor for such air heating and the load index. The fuel loss is obtained by measuring an amount of by-product in the flue gas as well as the opacity of the flue gas. These are multiplied by appropriate cost factors which in the case of opacity is pro-portional to a fine that would be due for violating certain limits for the opacity.  Minimum values are found for the fuel loss and air heating loss quantities, as air demand to the com-bustion operation is changed.  A minimum for the sum of the fuel and air heating losses is also obtained with the air demand of the combustion operation being set so that all of the losses are as low as possible.  In this way the costs of undesired air heat-ing, unburned by-products as well as potential violation of flue gas characteristic limits are utilized in determining the most economical air demand for the combustion operation.
