Abstract: System and apparatus for treating organic waste material, suited, for example, for the aerobic-thermophilic treatment of cattle manure. The waste material initially is commingled with an expanded, size limited dry cellulosic material in a mixing stage, preferably, a pug mill device, to achieve a bulk density and moisture content optimized for thermophilic digestion. A digestion arrangement is provided assuming a reliability for complete aerobic treatment of all material removed therefrom.

Abstract: The apparatus of this invention is designed for making foamed liquid solutions. In a specific application the foamed liquid is used for removing scale deposits from the interior surfaces of vessels, such as heat exchangers. The apparatus includes a foam chamber with a gas disperser section positioned inside the chamber. Ahead of the foam chamber is a final mixing section with a static mixer installed therein. A liquid concentrate, such as an acid solution, and a diluent liquid, such as water, are passed into the foam chamber. The liquids are mixed in the foam chamber and gas is bubbled into the liquid phase through the disperser section. The flow of gas and liquid into the foam chamber is controlled by flow regulators to achieve a continuous and uniform blending of the gas and liquid phases. From the foam chamber the foamed solution is carried into the final mixing section and passed through the static mixer to obtain a homogeneous cleaning solution, which is discharged into the vessel to be cleaned.

Abstract: Disclosed is a method and apparatus for cleansing roller-type applicators comprising a container, means for supporting and rotating applicators placed inside the container and means for spraying solvent on the rollers. One of the supporting means has a trough which enables the applicator to be cleaned whether or not it is mounted on a handle assembly. To obtain the desired cleaning action, applicators placed inside the container are sprayed with solvent while being held stationary or while being rotated slowly. Thereafter, the applicators are rotated at a high rate of speed to force the solvent with dissolved contaminants out of the applicators.

Abstract: A fertilizer product is disclosed which comprises the use of a fish emulsion encased in a water soluble capsule. The fertilizer product is prepared by concentrating the fish emulsion to evaporate most of the water found therein such that the emulsion will not cause the water soluble capsule to dissolve. To this concentrate, is added a liquifying agent and a surfactant which are blended and placed within the capsule.

Abstract: An elongated, hollow, cylindrical body is provided with an end wall at one end through which a liquid inlet opens and the other end of the body is open. The inside diameter of the body is of a size to snugly and slidably receive a paint roller therein and the length of the interior of the body is greater than the length of a paint roller. The open end of the body includes a hook for engagement with the support frame of a paint roller handle structure from which the paint roller to be cleaned is journaled. The paint roller to be cleaned is telescoped into the open end of the body to an extent greater than the length of the paint roller and the frame of the handle assembly is engaged with the hook carried by the body in order to prevent withdrawal of the roller from the body.

Abstract: Large amounts of industrial wastes are drawn by high vacuum into a scrubber and separator unit at the entrance of which the bulk wastes are flooded with water and reduced to slurry form. In the separator, the slurry is centrifugally spun and separated from the entraining air and delivered by gravity into a slurry tank from which the slurry is pumped to a remote disposal site. The air passes from the separator to a surge chamber where the air is spun and expanded and ridded of entrained moisture. The dry air in a clean state after passing serially through the vacuum producer and a silencer is expelled to the atmosphere. The equipment can be mounted on a vehicular base. The apparatus can operate to continuously and simultaneously remove and dispose of industrial wastes.

Abstract: A recirculating exhaust hood for a dishwasher may be comprised of an exhaust duct, a positive pressure plenum, a negative pressure plenum, and a fan for circulating air from the communicating dishwashing cavity through the positive and negative pressure plenums, and the exhaust duct. Air drawn through the intake of the fan is circulated through the positive pressure plenum to a supply slot. High velocity air exiting from the supply slot to a contiguous intake port of the negative pressure plenum creates a high velocity stream of air which by entrainment or by Venturi effect draws warm moisture laden air from the dishwashing cavity into the negative pressure plenum. The entrained moist warm air is then recirculated to the positive pressure plenum by means of the fan. A portion of the output of the fan is directed to an exhaust duct and removed from the dishwashing system.
