Title: Apparatus and method for inserting an additive liquid into a flowing fluid and discharging the resultant mixture

Abstract: APPARATUS AND METHOD FOR INSERTING AN ADDITIVE LIQUID INTO A FLOWING FLUID  AND DISCHARGING THE RESULTANT MIXTURE                       ABSTRACT OF THE DISCLOSURE           A dispensing assembly for discharging a flowing fluid into which a desired amount of an additive liquid has been inserted includes a container for the additive liquid which may be removed from a dispenser body.  The container is normally positively biased to a closed condition to prevent escape of the additive liquid.  Opening of the container is achieved through an interconnection with the dispenser body, opening of the container being effected upon establishment of a predetermined minimum pressure by the flowing fluid in the dispenser body.  Additive liquid is forced from the container into the flowing fluid by a metered amount of flowing fluid inserted into the container to cause a flexible pressure member to force the additive liquid from the container.          Opening of the container is not achieved until after the pressure member is exerting a force on the additive liquid in order to prevent dilution of the additive liquid by the flowing fluid.  Resistance to flow of the additive liquid from the container is minimized, so that the amount of additive liquid inserted into the flowing fluid is determined by metering of the flowing fluid, which is dependent upon the flow rate of the flowing fluid.  Thus, a constant proportion of additive liquid is inserted into the flowing fluid and the metering is essentially independent of the characteristics of the additive liquid.  All metering passages are easily accessible for cleaning.  An alternative rinse path is provided to insure rinsing of the dispenser body before and after opening of the container.  An appropriate flow regulating arrangement is utilized to selectively direct the flowing fluid through the alternative rinse path or to a pressure chamber to activate a mechanism for opening of the container.  Various modifications, such as a manual control for providing a selection of spray patterns for the mixture of additive liquid and flowing fluid, as well as for selecting clear water in a rinsing mode, and a bypass route to provide greatly diluted mixtures, may be employed.

Abstract: HID SODIUM LAMP WHICH INCORPORATES A HIGH PRESSURE OF XENON AND A TRIGGER           STARTING ELECTRODE     ABSTRACT OF THE DISCLOSURE         High-intensity-discharge sodium lamp incorporates as a starting gas xenon at a pressure between 50 and 300 torrs, in order to improve the lamp efficiency and the spectral power distribution of the discharge.  To facilitate lamp starting on a conventional pulse-type starting circuit, a trigger electrode is wrapped about the exterior of the arc tube proximate one of the lamp electrodes, with the poten-tial applied to the trigger electrode during lamp starting being the same as that which is applied to the other or more remote lamp electrode.  The starting pulse applied between the trigger electrode and the proximate lamp electrode initiates the lamp discharge.  The trigger electrode also extends along the outer surface of the arc tube contiguous therewith toward the other electrode and the discharge, once initiated, progresses toward the other electrode.  If the arc tube is pervious to the migration of sodium ions there-through under the influence of an electric field during the normal lamp operation, the trigger electrode is effectively removed from the circuit by a switch or a high impedance to prevent such sodium ion migration.

Abstract: ABSTRACT       A method and apparatus are disclosed for transferring heat to or from metal hydrides contained in storage containers as hydrogen gas is being charged to or withdrawn from the storage containers, wherein the hydrogen gas being charged to or withdrawn from the storage containers functions as a convective energy carrier. A plurality of the containers are connected together in flow communication in series, so that when a pressure differential is established across the series of containers, hydrogen gas associated with the metal hydride will flow from one container to the next container in the direction of the lower pressure. A pressure differen-tial is created across the series of containers by charging hydrogen to either the first or last container in the series, or by withdrawing hydrogen from either the first or last container in a series of containers that has been previously charged with hydrogen. Hydrogen gas flowing through the donduits connecting adjacent containers is heated or cooled in heat exchanger means associated with the conduits. The pressure differential across the series of containers can be periodically reversed by periodically alternating charging hydrogen to the first and last containers of the series during the charging of said containers, and by periodically alternating the discharge of hydrogen from the first and last containers of the series when hydrogen is being withdrawn from the series of containers.

Abstract: A B S T R A C T      A surgical collection bag for post operative use having two opposed walls, secured together by a perimeter weld.   One of the walls has an inlet opening through which the contents of the intestine of a patient can flow into the interior of the bag.   The same wall also has a vent which is impervious to solid material and liquid from the intestine of the patient but which is pervious to gases.   Welds inside the bag together with the perimeter weld define a pathway through which gases can flow from the interior of the bag to the vent.          This pathway includes one or more vents through which gases must pass before they reach the vent.   These gateways are sufficiently narrow at least substantially to prevent the passage of solid materials and liquids.          If desired, the welds can be discontinuous to provide a multiplicity of gateways.

Abstract: Abstract of the Disclosure Apparatus is disclosed for transmitting video signals which produce images that can be viewed comfortably as two-dimensional images but when viewed through special glasses appear to be three dimensional.  An illusion of depth is created for scenes including a moving object by combining one chrominance component of a past field with the complementary chrominance component of the current field.          By "registering" the moving objects of the past and current fields, the background (stationary) objects of the past and current fields are displaced slightly relative to each other.  These displaced images appear in complementary colors and can be viewed normally if the displacement is slight, with an unobjectionable color fringe.  When viewed through appropriately filtered glasses, the displaced images create a three dimensional illusion.

Abstract: ABSTRACT     An arrangement for hydraulic transport of precipitator dust accumulated in a precipitator plant having a plurality of hoppers consecutively arranged in the flow direction of a gas to be cleaned.  There is a sluice chamber for each hopper from which it is separated by a respective discharge valve and each sluice chamber has an inlet for rinse water and an outlet for a mixture of rinse water and precipitator dust received through the discharge valve. A sluiceway connects the outlet of each sluice chamber to the inlet of the preceeding chamber as defined by the gas flow with fresh rinse water being supplied to the inlet of the last sluice chamber as defined by the gas flow direction.  An outlet gutter for the first sluice chamber is closed by a weight loaded flap so that this opens to discharge rinse water dust mixture only when the hydrostatic pressure exceeds a predetermined chosen level.  This prevents atmosphere from entering the system through the discharge.  Additional rinse water can be added to the inlets of all of the preceeding sluice chambers (as defined by the gas flow direction) each having a respective shutoff valve.
