Abstract: The present invention provides a composition and method of administering same for inhibiting the growth of microorganisms. The composition of the present invention includes sufficient amounts of a peracetic acid or peracetic acid/peracid blend and a non-oxidizing biocide. The method of the present invention includes the step of adding sufficient amounts of the peracetic acid or peracetic acid/peracid blend and the non-oxidizing biocide to industrial process waters.

Abstract: To regulate the immune response to an antigen, a subject with the antigen is injected with polyanionic polysaccharide derivative: (1) having a molecular weight of between 1,000 and 600,000; (2) selected to correspond to the antigen; (3) not being cytotoxic at an effective dosage; and (4) stimulating a cell-mediated immune response. For virus, as an example, mycodextran sulfate or pustulan sulfate may be used in sufficient quantities to stimulate cell-mediated immune responses without stimulating synthesis of gamma-E globulin and gamma-G globulins. The polyanionic polysaccharide derivative may be injected alone to stimulate cell-mediated immune responses to antigens in a diseased subject.

Abstract: A drum lid for a ventable drum has a depression formed in the surface of the lid. A vent valve is placed in the depression and extends through the lid. The valve has a valve outlet which opens into the reservoir in the lid. During venting the reservoir is filled with water and the valve stem is slowly opened. The gas escapes into the water in the reservoir in the form of bubbles. When the bubbles stop the tank is vented and the lid can be removed.

Abstract: Glutaraldehyde is effective in controlling Zebra mussels found in industrial process waters.

Abstract: A system for emitting, in sequence, a plurality of different scents includes a plurality of holders for scent-bearing chips; a mechanism for propelling these scents from a system; a mechanism for conveying, selectively, any desired scent holder into operative relation with the propelling mechanism; and a mechanism for actuating the propelling mechanism to propel scent from any desired scent holder in response to a programmed, predetermined sequence of scents of predetermined duration.

Abstract: To regulate the immune response to an antigen, a subject is injected with the antigen and a polyanionic polysaccharide derivative having a molecular weight of between 10,000 and 600,000 selected to correspond to the antigen. For virus, as an example, mycodextran sulfate or pustulan sulfate may be used in sufficient quantities to stimulate cell-mediated immune responses without stimulating synthesis of gamma E globulin and gamma G globulin. The polyanionic polysaccharide may be injected along to stimulate cell-mediated immune responses to antigens in a diseased subject.

Abstract: An improved card cage assembly used in data processing equipment to hold printed wire boards containing electrical circuitry. The improved assembly has a rear bar and a front bar with extruded channels formed therein. The channels receive thread-forming screws and a nut strip for ease in construction and for the elimination of back panel stresses.
