  • Patent number: 5000566
    Abstract: This optical velocimeter may be installed in an aircraft to measure the true airspeed and the angles of attack and of sideslip of the aircraft. Alternatively, the velocimeter may be mounted in a wind tunnel to measure the velocity of the airstream passing through the wind tunnel. In either case, the points of reference for measurement are the large number of aerosol particles that are entrained in the air and are assumed to have the same velocity as the oxygen and nitrogen molecules of the air itself.The velocimeter comprises a plurality of optical transmitters and optical receivers. Each transmitter includes a laser operated in the continuous-wave mode and a laser operated in the pulsed mode. The laser operated in the continuous-wave mode generates a "precursor light sheet" at some distance from the aircraft whose velocity is to be measured or in the wind-tunnel airstream whose velocity is to be measured.

  • Patent number: 4969043
    Abstract: This is an apparatus for sharpening and otherwise enhancing images such as those produced on a screen or on the face plate of a cathode-ray tube. Regarding an image as being composed of a very large number of elements called "pixels," the apparatus of this invention enhances those of the pixels which appear at points of rapid transition between light and shade in the image. The apparatus comprises a plurality of substrates superimposed upon one another, optically in series. A first such substrate includes an array of filters and lenses which together form a "mask" that operates upon selected portions of the light input thereto to multiply certain portions of the light input with respect to certain other portions of the light input. The light upon which this operation has taken place proceeds to a second substrate where it is detected to generate electrical signals expressive of the intensities of the respective portions of the light input.

  • Patent number: 4819909
    Abstract: A self-closing valve, having means to discharge a predetermined volume of water for each cycle of operation, is disclosed. The valve includes the arrangement of timing means which determines the elapsed time for its operational cycle, a one-way valve means to expel air from the metering chamber during the actuating cycle of the valve, and air metering means which replaces air entering the mixing chamber at a constant uniform rate, all of which cooperate with the valving means to discharge a predetermined volume of water.

  • Patent number: 4796666
    Abstract: The invention relates to a sanitary single-handle mixing valve having control elements composed of at least two discs, one of which serves as a fixed valve seat disc with two inlet openings for cold and hot water. For purposes of operating the mixing valve in combination with thermally or hydraulically controlled flow heaters, the centroids of the port areas of the inlet openings, or at least the centroid of the port area of the cold water inlet opening, is shifted a few degrees of angle towards the cold water setting in order to achieve hydraulic asymmetry when the operating handle is in its central position.

  • Patent number: 4794952
    Abstract: The invention relates to a combination single-handle mixing valve and appliance valve assembly, mounted in a common housing and having common hot and cold water connections. The appliance valve, axially positioned between the mixing valve cartridge and the manifold, is in fluid communication with the mixing valve and includes a handle to supply water to the appliance.

  • Patent number: 4784368
    Abstract: A self-closing valve assembly for sanitary installations is disclosed. The valve assembly includes upper and lower valve housings which define a metering chamber that is normally filled with a metering fluid. A metering means, shiftably mounted in the lower valve housing, includes a first one-way valve means which displaces a predetermined volume of the metering fluid when said valve assembly is shifted to its opened position. A closure means, which includes a second one-way valve means, is operably coupled to the metering means to automatically shift said metering means from its opened to its normally closed position, by transferring the displaced volume of said metering fluid in the metering chamber through a second one-way valve means after a predetermined period of time has elapsed, to thereby close said valve assembly.

  • Patent number: 4765002
    Abstract: An illustrative embodiment of the invention provides a peripheral flange generally perpendicular to the plane of the lavatory basin. The flange has a generally downwardly, inwardly sloping surface to enable the splash water to flow into the basin within the lavatory. As the flange sweeps around the periphery of the lavatory it develops into a massive spout support. The spout support enables the spout to direct water into the basin without causing the spout to extend across the basin surface. The support also has a protruding portion that establishes a reentrant basin surface in which the overflow drain is concealed from view when the lavatory is installed.
