    Abstract: A multi-chamber loudspeaker enclosure comprises a primary chamber having a principle interior volume and a secondary chamber having a minor interior volume substantially smaller than the principal interior volume. The secondary chamber comprises an elongated housing mounted to a front wall of the primary chamber. The secondary chamber has a speaker mounting opening from the enclosure and an interior opening that opens simply and directly from the secondary chamber into the primary chamber. The two openings are substantially coaxially aligned. The speaker mounting opening is the only opening from the inside of the enclosure to its exterior. The secondary chamber projects from one of the faces of the front wall of the primary chamber. The length of the secondary chamber between the two openings is substantially greater than the length of a loudspeaker mountable in the speaker mounting opening. This multichamber loudspeaker enclosure has enhanced freedom from resonance. A loudspeaker enclosure especially suitable for enhancing bass response is provided by a secondary chamber housing of large mass in which the walls are formed from a dense, solid material that inhibits physical motion or vibration being transmitted to the walls of the enclosure from vibrations induced in the loudspeaker during its operation.

    Abstract: An adjustable shower head is defined so that in one operating state thereof, the discharge from the shower head, upon contact with the body of a user, produces a massage-like effect. The shower head includes a body which defines therein a cavity and which has a front face defining an opening therein. Means are coupled to a rear portion of the body to adapt the body to be connected to a source of water for flow of water from the source to the cavity. A nozzle is disposed in the cavity with a discharge end thereof mounted in alignment with the opening fo discharge of water from the cavity only through the nozzle. The nozzle has no moving parts and is arranged to produce a randomly directionally unstable discharge characteristic in water discharged therefrom during use of the shower head. Modulatng means are mounted to the body and are operable by a user of the shower head for modulating the effective force for water discharged by the nozzle.

    Abstract: An ornamental fountain nozzle for generating a plurality of nonaerated water streams includes a body defining a chamber therein. A plug is disposed across an upper water outlet opening of the body and has a portion of its length outside the body. A plurality of grooves are formed at intervals in the circumference of the plug and have their lengths substantially aligned with the length of the plug. The grooves have a substantial portion of their length disposed within the body. The grooves have lower ends which communicate with the chamber and upper ends which communicate with the exterior of the nozzle only through the peripheral walls of the plug above the upper end of the body. Each groove has a base element therealong located farthest inwardly of the groove from the plug peripheral walls. The base element of each groove is sloped outwardly relative to the length of the body proceeding upwardly along the groove. The grooves also have side wall surfaces between the groove base element and the adjacent peripheral walls of the plug, and these side walls converge toward each other proceeding upwardly along the length of the groove. Between the grooves, the plug peripheral walls are engaged in surface-to-surface contact with the interior of the body adjacent the top of the body so that the only outlet of water from the chamber between the plug and the body is via the grooves.

    Abstract: A liquid discharge nozzle for producing a randomly directionally unstable liquid discharge characteristic includes a body having a chamber therein. An inlet is provided to the chamber. An outlet duct is defined from an end of the chamber to the exterior of the body. The outlet duct has a straight constant diameter first portion communicating from the chamber to a flared second portion of the outlet duct. The duct first portion has a ratio of length to diameter in the range from about 4 to about 18. The diameter of the duct second portion increases proceeding away from the chamber from an initial diameter essentially equal to that of the duct first portion. While the ultimate flare angle of the duct second portion relative to the axis of the duct first portion may exceed 6.degree., if the ultimate flare angle is greater than 6.degree. then the duct first and second portions are coupled directly by a transition flare in which the ultimate flare angle is developed transitionally in at least one transition section having a flare angle in the range of about from 2.degree. to no more than 6.degree.. The chamber is defined in cooperation with the positions of the inlet and outlet duct relative to each other for substantially linear flow of liquid through the duct first portion during operation of the nozzle.

    Abstract: A family of aerating liquid discharge nozzles, each having an elongate body defining a duct therethrough between lower and upper liquid inlet openings defined at opposite ends of the body, is described. A plug is disposed across the duct and has liquid flow passage means defined therethrough by a plurality of grooves formed in the plug sidewalls. The grooves are spaced uniformly around the circumference of the plug and have an aggregate crosssectional area substantially less than the cross-sectional area of the duct at the location of the plug in the duct. A conical projection extends from the plug toward the liquid inlet opening coaxially of the duct, the radius of the projection, at its base, being at least equal to the minimum radius of the plug.
