Abstract: ABSTRACT OF THE DISCLOSURE           A fluid energy mill of the confined vortex type is designed to permit the simultaneous drying and grind-ing of slurries of pulverulent solids, e.g., pigment slurries.  The slurry is directed into a passageway leading to the grinding chamber in such a way as to be enveloped and atomized by a flow of gaseous drying fluid, e.g., high pressure steam, of at least sonic velocity. The solids become at least partially dried before enter-ing the grinding chamber but with little or no tendency to adhere to the walls of the passageway leading thereto.

Abstract: ABSTRACT OF THE DISCLOSURE         A vaporizer for directing water vapor into the air after relatively large water particles have been removed from the water vapor within the vaporizer itself.  The interior of the vaporizer has structure defining a serpentine path along which the water vapor moves, such structure including a first chamber having electrode means therein for generating steam forming the water vapor and a second chamber separated from the first chamber by a vertical partition.  The steam after being generated flows along the serpentine path by rising in the first chamber, passing over the top of the partition and downwardly into the second chamber, then moving upwardly toward and through an exit orifice and into the air.  During the downward portion of its path of travel, the relatively large water particles separate from the water vapor by gravity and return to the second chamber, the latter being in fluid communication at its bottom with the first chamber.

Abstract: ABSTRACT     The invention relates to stripping part of the covering from an article comprising a substrate and a covering.  In one aspect the invention provides apparatus comprising force-exerting means and cooperating stripping means which are adapted to exert a compressive force on a section of said article, said stripping means having a shape and hardness such that, when a sufficient compressive force is exerted, the stripping means causes substantial deformation of the covering but, if it contacts the substrate, itself undergoes plastic or elastic deformation without causing substantial deformation of the substrate; preferably the force-exerting means is a second stripping means.  In another aspect the invention provides a process in which such apparatus is used to strip part of the covering from an article comprising a substrate and a covering; the covering is deformed (but the substrate is not) by exerting a compressive force on the article, and the covering is then severed and stripped by moving the article and the apparatus relative to each other, while maintaining the compressive force.

Abstract: FLUORESCENCE QUENCHING WITH IMMUNOLOGICAL PAIRS IN IMMUNOASSAYS                  ABSTRACT OF THE DISCLOSURE         Immunoassays arc provided employing antibodies and fluorescer-quencher (F-Q) chromophoric pair, wherein one or both of the chromophoric pair are bonded to antibodies.           Depending on the particular ligand of interest, various reagent combinations can be employed, where the amount of quenching is directly related to the amount of ligand present in the assay medium.         In carrying out the assay, the unknown and antibody specific for the ligand of interest to which is bound one of the F-Q pair, are combined in an aqueous buffered medium.          Depending on the protocol, different assay reagents are employed in the aqueous buffered medium:  (1) ligand analog bonded to the other of the F-Q pair;  (2) antibodies specific for the ligand to which is bound the other of the F-Q pair or; finally,  (3) a combination of a plurality of ligands bonded together through linking groups to a hub molecule, usually a polymer, in combination with antibody bound to the other of the F-Q pair.  The composition is irradiated with light at a wavelength, absorbed by the fluorescing molecule and the amount of fluorescence determined. By employing appropriate standards, the presence and amount of the ligand can be determined.

Abstract: A STATION PROTECTOR WITH A THREE-ELECTRODE GAS TUBE ARRESTER                   Abstract of the Disclosure A station protector is used in protecting pairs of telephone lines at a station from high voltages or surge currents occurring on the telephone lines and includes a base assembly having an upstanding wall at one end, an arrester mounting section adjacent the opposite end, and a pair of line terminals and a ground terminal disposed between the wall and the arrester mounting section.  A removable ground clip assembly is disposed in the arrester mounting section so that a three-electrode gas tube arrester having a line electrode at each end of the tube and a ground electrode therebetween can be mounted on the base assembly to provide protection for the telephone lines.  The ground clip assembly contains movable contact assemblies insert-able into each of a pair of cavities located in the arrester mounting section and resiliently biased so that a contact rod portion in the contact assembly is normally coupled to the ground terminal.  When a case having the three-electrode gas tube retained therein is mounted on the ground clip assembly such that the ground electrode is coupled to the ground terminal, contact shafts fusibly linked to each of the line electrodes cause the contact rod portion of each of the contact assemblies to be disconnected from the ground terminal and to connect the contact shafts to the line terminals.  In the preferred embodiment, a cover is slidable over the base assembly so as to protect the base assembly from the weather, insects and tampering.

Abstract: ENGINE AIR-INLET SILENCER     ABSTRACT OF THE DISCLOSURE     The invention contemplates provision of a relatively large cavity chamber as the means of supplying a substantially unimpeded flow of inlet air to the carburetor system of an internal-combustion engine.  Air is admitted to the chamber via a plurality of tubular passages.  Each of the passages is related in sectional area and length, to the effective volume of the chamber, for reduction of external transmission of carburetor-intake noise.  And the number of passages is selected to assure that the cumulative sectional area of all tubular inlet passages so satisfies the most extreme inlet-airflow demand by the engine that the supply to the engine is substantially unimpeded.  Illustrative embodiments are described.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for the generation of power and for increasing the temperature when a working fluid is circulated through a fluid path within two concentric members which may both be rotors.          The working fluid is compressed by centrifugal force in an outwardly extending portion of the fluid path and expanded against centrifugal force in an inwardly extending portion of the fluid path.  Heat is ex-changed between two streams of the working fluid within the path in a regenerative type heat exchanger, and heat is exchanged with the working fluid in a high temperature heat exchanger located downstream for the working fluid of the heat addition in said regenerative heat exchanger.          An additional heat exchanger, at a lower temperature than the high temperature heat exchanger, may be provided to exchange heat with the working fluid downstream for the working fluid of the heat removal in the regenerative heat exchanger.  Working fluid may be any suitable gas such as air.  The high temperature heat exchanger is usually provided with a heat transfer fluid flowing through the rotor shaft.  Work is produced by the device when operated as a turbine, and work is usually required by the device when operated as a heat pump.
