Abstract: An improved push broom assembly is disclosed which includes a shroud portion retaining a plurality of bristles thereon and a neck portion angularly protruding from a face of the shroud portion opposite to that which retains the bristles thereon. The neck portion is comprised of two pieces, a first piece integrally formed with the shroud portion and including a recess, and a second piece designed to removably fit into the above noted recess and to combine with the first piece to comprise a completed neck portion. The completed neck portion comprised of the first and second pieces has internal threads which mesh with external threads on a broom handle and further includes exterior threads which mesh with a cap device having interior threads thereon and threaded over the neck portion so as to retain the first and second pieces thereof together.

Abstract: The amount of gaseous flammable propellants such as dimethylether, difluoroethane, propane, butane, and the like can be increased to as high as from 30 to 50% by weight of a propellant composition by dissolving the normally gaseous propellant in the dispersed oil phase of an oil-in-water microemulsion. The aerosol propellant compositions can be simply prepared by metering the ingredients other than the gaseous propellants into an aerosol dispenser, then adding the gaseous propellant, under suitable pressure, into the aerosol dispenser whereby simply shaking of the dispenser will result in the spontaneous formation of an oil-in-water microemulsion which is clear and stable and which can contain as much as about 50% by weight of the gaseous propellant without causing flaming when the composition is sprayed directly into a candle flame.

Abstract: A passive dispenser for containing a quality of solution isolated from a body of liquid and for causing a predetermined volume of said solution to issue from the dispenser solely under conditions of gravity flow in response to the level of said body of liquid being lowered from a first elevation to a second elevation, said dispenser adapted for placement at the bottom of said body of liquid, comprising an upper section which is a cuplike member having an open bottom, the lower peripheral edge being an annular channel; a lower section which is a cuplike member having an open top, said cuplike members providing an internal reservoir for storage of cleaning solution formed upon dissolution of a water-soluble cake contained with said reservoir, the top peripheral edge of the lower section being disposed within said annular channel to define a discharge/refill conduit connecting said reservoir with the body of liquid and comprising two chambers in fluid communication with each other, one chamber being adjacent to

Abstract: Aqueous enzyme preparation stabilized with a salt of a lower molecular weight acid in the presence of alcohol.

Abstract: The present invention provides a passive dispenser having dual sections for use in a toilet tank in which a disinfectant solution to be dispensed is stored in one section and substantially isolated from the water in the toilet tank, the section comprising a product chamber having a venting means and a refill/discharge pathway. The refill/discharge pathway is vented to the atmosphere and has an inclined conduit extending downwardly from the top portion of the pathway to the product chamber. Hydrostatic head obtained by use of refill/discharge pathway venting conduit in conjunction with the inclined conduit retards the outflow of solution from said product chamber during quiescent periods. Constriction means in the refill/discharge pathway venting conduit is preferred to provide turbulence during the refill cycle. In the other section of the dispenser, a soluble composition comprising a detergent, deodorant or other additive materials is stored.
