  • Patent number: 4305117
    Abstract: An ornamental water fountain is artificially illuminated by separate sets of differently colored lamps illuminated by a color blending system that responds to variations in musical tones. In one embodiment, there are three sets of lamps in separate principal colors, namely, red, blue and green, and the intensity of light from each set of lamps is independently controlled during the playing of a musical number, producing a multitude of different colors reflected by the fountain in response to variations in the amplitude and frequency of the musical tones. The color blending system operates in response to an input voltage representative of musical tones produced over a wide range of audio frequencies from a phonograph, tape player, radio receiver, or the like. The input voltage is separately coupled to low pass, band pass and high pass filters for producing separate frequency band signals representative of the content, i.e.

  • Patent number: 4204631
    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.

  • Patent number: 4055302
    Abstract: A liqud 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 chamber, the inlet and the outlet duct are cooperatively related so that the direction of liquid flow into the chamber is substantially opposite to the direction of liquid flow from the chamber and so that the liquid flow characteristic through the outlet duct is linear. 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 one-third 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.

  • Patent number: 4055306
    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.

  • Patent number: 4055301
    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.
