Abstract: TITLE            IMPROVED SUCTION NOZZLE DREDGE HEAD                        ABSTRACT         This invention provides means to mechanically assist suction action of a nozzle dredge head in dislodging particles embedded, e.g., on the ocean floor.  The mechanical assist means comprises a plurality of fingers extending downwardly from along the upper edge of an obliquely downwardly and forwardly facing nozzle opening.  The fingers are resiliently connected to the nozzle and capable of being bent under so as to be juxtaposed across, and thus temporarily block, the nozzle opening, whereby the intake of oversized particles is prevented.

Abstract: METHOD AND APPARATUS FOR REGULATING THE SIZE AND FREQUENCY OF BUBBLES EMPLOYED           FOR MIXING LIQUIDS            ABSTRACT OF THE DISCLOSURE       A few large, fast rising gas bubbles are generated near the bottom of a sample container and the upward movement of the bubbles causes a mixing action of the sample.  The bubbles result from the periodic injection of discrete quantums of gas into the bottom of the container.  The volume of a discrete gas quantum determines the size of a resulting bubble.  Both the volume and frequency of generation of the quantums of gas are controlled by a timing circuit which operates a solenoid valve that permits each discrete quantum of gas to pass into the sample container.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus are provided for converting digi-tal form the analog ultrasonic echo signals received as a result of cyclically transmitted ultrasonic search signals intercepting an acoustic discontinuity in a workpiece.  The ultrasonic echo signals are divided into a discrete number of raster-like scan lines which are scanned electronically by a microprocessor.  Digital signals are generated for each line of the raster-like scan and such signals assume either a first or second state along the scan line in accor-dance with the signals amplitude along that line.  As successive scans are made at progressively higher amplitudes of the echo sig-nal, the amplitude requires for varying the digital signal between the states for a particular scan line is incrementally increased with each scan line.  A comparator receives at a first input the echo signals and at a second input a signal from a digital-to-analog converter whose output is incrementally increased on successive scan lines by the microprocessor.  The outputs of the comparator are placed into storage in the microprocessor.

Abstract: Abstract A self-priming passive dosing dispenser for issuing, beginning with the first flush, a quantity of a toilet tank additive solution into a toilet tank as the water is draining therefrom while the toilet is flushing.  A preferred dispenser comprises a reservoir for containing a quantity of a toilet tank additive type product and in which reservoir a solid type product can be dissolved to form a product solution.  Means are provided for flooding the reservoir through the discharge standpipe upon initial immersion of the dispenser into the toilet tank water to ensure first flush dispensing of product solution.  In steady state operation, while the water in the toilet tank is receding from about the dispenser, a predetermined dose-volume of toilet tank water is vacuum-transferred from a measuring cavity located within said dispenser into said reservoir through an inlet conduit, and a substantially equal dose-volume of the product solution is dispensed through a discharge standpipe.  The dispenser may further comprise an internal baffle to precipitate mixing and agitation inside the dispenser which promote dissolution.  Upon reaching steady state operation, the dispenser provides an air-lock when immersed in a full toilet tank which air-lock isolates the product and product solution from toilet tank water which surrounds the dispenser during quiescent periods.           Plural product co-dispenser which embody the present invention are also disclosed.

Abstract: RECORDING METHOD AND APPARATUS THEREFOR            ABSTRACT OF THE DISCLOSURE             A recording method and apparatus therefor make the recording of images in the following process:  A powder-like toner having a high electric resistivity and a charge retention property is held on a donor and is brought into contact with a multi-stylus electrode.   A pattern signal is applied to the multi-stylus electrode and the toner is elec-trically charged or quenched by the charge injection of the multi-stylus electrode and a charge distribution is formed in the toner on the donor, corresponding to the pattern signal.      The charge distribution is used for the formation of a visible image.  For example, by transferring the toner selectively to a recording sheet in accordance with the charge distribu-tion, a visible pattern corresponding to the pattern signal is obtained on the recording sheet.  The visible pattern can be recorded on an electrically conductive recording member or a recording member having uneven surface by utilizing an image transfer medium.  By transferring toner to a latent image bearing member on which a latent electrostatic image is formed, a visible pattern modified by the pattern signal can be obtained.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to an apparatus for maintain-ing the desired temperature of a fluid, or more specifically, to reducing the temperature of the fluid to a desired level. The apparatus generally relates to one including a heat ex-change coil through which the fluid to be cooled passes and over which an air stream is moved to absorb heat from the coil.  In such an arrangement, it is common to increase the heat transfer efficiency of the coil by maintaining the same in a wet condition by means of a water spray or cascade, for example.  In this manner, evaporation of the water causes an accelerated transfer of heat from the fluid in the coil for a given amount of air flow thereover than would be the case if the coil surface was not drenched.  The present invention is directed to the disposition of a propeller air moving means sufficiently downstream of the cooling coil so as to be sub-stantially free of air flow obstructions.  In addition, the usefulness and efficiency of the apparatus is improved by the inclusion of a novel air recirculation damper having an air foil configuration which is pivoted about its trailing edge.
