Abstract: An interference fit assembly comprises a wick constructed of a porous polymer and a wall constructed of a polymer for interference engagement with the wick. The wick has a weight of 3.3 grams.

Abstract: A method and apparatus for surface treating metal pipes includes introducing a treatment liquid into a first distribution chamber having a flat bottom surface, and dropping the treatment liquid onto at least a portion of the outer peripheral surface of the metal pipe through a plurality of holes formed in the bottom surface of the first distribution chamber. Preferably, a distance between the bottom surface of the first distribution chamber and the metal pipe is maintained constant as the outer diameter of the pipe varies. The treatment liquid may be introduced into a second distribution chamber having a flat bottom surface, and the treatment liquid may then be introduced into the first distribution chamber through a plurality of holes formed in the bottom surface of the second distribution chamber. It is possible for the first distribution chamber to simultaneously drop the treatment liquid onto at least two metal pipes.

Abstract: A static air freshener has a frame formed of or with plastic beads impregnated with a scent or aroma. The rate of release of the scent is controlled by the area of the frame to define the useful life of the air freshener. An insert may be place in a void defined by the frame. The insert has a thematic image that may be correlated to a thematic image on the header card of a bag or sack sized to contain the air freshener for positioning at or on the point of sale device.

Abstract: An upright-type fire protection water spray mist nozzle has a base defining an orifice through which fire-retardant fluid can flow, an inlet section having an upstream end and defining a conduit for flow of fire-retardant fluid along a orifice axis and leading to an upstream end of the orifice, with a diffuser element defining an impingement surface that is at least substantially imperforate in an axial direction and positioned for impingement by a stream of fire-retardant fluid flowing from the orifice in a stream direction along the orifice axis, the diffuser element being positioned generally above a horizontal plane through a downstream end of the orifice.

Abstract: Aromatic liquids substances such as deodorizers, room freshener compositions, perfumes, fragrances and the like are dispensed in vapor phase from a container holding the substance in liquid phase. In the best mode, the container is in conical form, having a controlled opening or openings through which the liquid volatile substance is dripped downwardly onto a conical substrate, from which it is dispensed in vapor phase into the atmosphere. The dispenser is configured such that it may stand, as on a counter or any flat surface, or may be hung, as in a closet, in an automobile, or the like.

Abstract: The present invention is directed to air freshener devices with child resistant features. The air freshener devices comprise (a) a housing having a socket portion; (b) a container for holding a liquid to be evaporated by heat, the container having a body for storing the liquid and a neck connected to the body, the neck engaging the socket portion of the housing thereby supporting the container on the housing, the neck having a passage therethrough; (c) a retaining ring fixed in the passage of the neck of the container; (d) a wick having an upper portion extending through the retaining ring and a lower portion extending into the body of the container, the lower portion of the wick absorbing the liquid from the container and moving the liquid from the lower portion into the upper portion of the wick by capillary action; and (e) heating means in the housing for heating the upper portion of the wick above the neck of the body to evaporate the liquid from the wick.
