Abstract: ABSTRACT OF THE DISCLOSURE        Movable means are provided interiorly of a confined line on a substantially horizontal plane through which fluids, such as, for example, liquids and gases, flow to inhibit the adherence of particulate matter within the line.  The movable means comprise relatively solid objects which bounce and tumble within the line to contact the interior of the line.  The relatively solid objects, which may be in the form of chains, wires, cables or any other solid media whether consisting of separate or joined components, also function to prevent the liquid passing through the line from assuming a dry or precipitate state as it is splashed or otherwise distributed about the entire interior periphery of the line.  The action of the tumbling media also provides com-plete contact between the gas and liquid flowing through the line to achieve the appropriate chemical reaction therebetween for cleansing of the gases.  The tumbling media causes the gases to flow in a tortuous path through the confined line.

Abstract: APPARATUS FOR GENERATING AN ELECTRICAL    SIGNAL INDICATIVE OF LIQUID LEVEL               ABSTRACT OF THE DISCLOSURE        Apparatus for generating an electrical signal indicative of the level of a liquid stored in a reservoir.          The apparatus includes first and second probes spaced from one another and extending into the reservoir.  Each of the probes includes a metal electrode surrounded by a pre-ferably dielectric material.  The liquid to be measured contacts the dielectric material, but does not directly contact the electrodes.  A preferably alternating voltage is applied across the electrodes and the impedance there-between is sensed.  The impedance between the electrodes varies as a function of the level of the liquid in the reservoir and this impedance is substantially greater than the impedance between the probe areas of contact with the liquid.  In effect, the liquid is treated as a conductor because its impedance is negligible as compared to the impedance between the probe electrodes, this impedance varying as a function of liquid level.

Abstract: HIGH STRETCH YARN TEXTURING AND PACKAGE PRODUCTION                ABSTRACT OF THE DISCLOSURE          A method and apparatus for one step texturing and package preparation of high stretch continuous fila-ment yarn for ultimate package dyeing.  Continuous fila-ment yarn is fed from a supply across a false twisting assembly, and a false twist is imparted thereto.  The yarn is then passed over a roller and directed generally downwardly toward a take-up assembly including a dye spring.  The yarn is overfed to the dye spring so that the yarn may relax completely and will have maximum skein shrinkage after dyeing.  This is accomplished by passing the yarn through an air jet, resulting in an overfeed of up to 70-100%, which overfeed is not possible with con-ventional methods.  The yarn package formed is soft, and may be package dyed according to conventional procedures.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a rotary pipe coupling which is particularly useful for connecting a spout to a body of a faucet.  A known design utilizes a split metal ring which is engaged by a coupling nut, sealing being effected by an O-ring.  Pressure surges caused, for example, by solenoid actuated water shut-off valves in dishwashers, can sometimes cause a spout of prior art design to blow out of the body of the faucet.  The coupling of this invention eliminates this problem by providing a coupling ring of relatively hard but resilient material such as plastic which has an internal rib which engages with a groove in the spout.  The ring has a first face which bears against an internal surface on the end of the pipe portion to which the spout is connected and a further face which bears against an internal surface on the coupling nut.
