Abstract: S P E C I F I C A T I O N             IMPROVED BELT BACK-UP APPARATUS AND  COOLANT APPLICATION MEANS FOR        BELT CASTING MACHINES            Inventor:  JOHN M. A. DOMPAS                 ABSTRACT OF THE DISCLOSURE           In twin-belt casting machines for continuously casting molten metal improved belt back-up apparatus and coolant application means are provided.  The front faces of the casting belts are held firmly against the moving edge dams by wide belt-supporting elements in the form of cylindrical collars on the back-up rollers or longitudinally extending fixed guide members engaging the reverse surfaces of the belts and positioned in alignment with the respective side dams and laterally spaced apart a distance no greater than the lateral spacing of the moving side dams.  Nozzles are absent from the coolant supply means in the positions where the belt-support-ing elements are engaging the reverse surfaces of the casting belts.  The cylindrical collars may extend inwardly somewhat beyond the inner faces of the side dams and may have peripheral grooves therein for permitting liquid coolant to travel along the reverse surface of the casting belt through said grooves, with narrow fins on the back-up rollers for engaging and sup-porting the reverse surface of the casting belt between said cylindrical collars.  The fixed guide members extend between the casting belt and the back-up rollers and are secured by lateral braces extending between the back-up rollers and have saddles therein for receiving journal portions of the rollers fitting in said saddles.

Abstract: ABSTRACT OF THE INVENTION       An improved aeration apparatus for use in sewage treatment plants to dissolve oxygen into the sewage.  The aeration apparatus is specifically designed for use in combination with a single home sewage treatment unit.          The aeration apparatus includes a motor assembly for rotation of a propeller through a downwardly extending drive shaft.  The propeller extends downwardly into a draft tube so as to pump the liquid to be aerated upward therethrough.  A deflector plate directs the rising liquid radially outward in all directions.  A slinger is positioned about the drive shaft immediately below the deflector plate.  The motor is designed to pull only fresh air into the aerator housing.  To avoid clogging the propeller is free to move in one direction or another when a large object comes through the draft tube.

Abstract: MULTIPLE PURPOSE NOZZLE     Abstract of the Disclosure A multiple purpose nozzle includes a tubular member having a bore and communicating passage network therethrough and through which material to be dispensed is adapted to pass.  An adjustable cap is coupled with the tubular member having an orifice in the end wall thereof of predetermined configuration.  The cap is coupled to the tubular member so that it may be shifted between shut-off and open positions.  In addition the cap is provided with a passage which form part of the passage network when the cap is shifted to the open position.  In the closed position the cap passage is not aligned with the passage network of the tubular member and thus prevents the material from being dispensed.  The cap is adapted to assume at least one other and open position at which the cap passage is aligned with the passage network and the material to be dispensed is adapted to pass in a selected predetermined discharge pattern through the bore passage network and orifice.  The passage network of the tubular member is offset from the orifice of the cap when the cap is adjusted to shut-off position whereby only the orifice in the cap and edge of the tubular member are exposed to atmosphere thereby preventing drying out of the material to be dispensed when the nozzle is not in use.

Abstract: Encapsulation by Entrapment Abstract of the Disclosure Water-soluble and water-insoluble solid and liquid core materials are encapsulated by the same method.  Core materials are simply entrapped in a matrix of water-insoluble polyhydroxy polymers which are insolubilized from their corresponding water-soluble xanthates in the presence of the core materials.  Encapsulation of biologically active compositions provides a shield against hostile environments, improves safety in handling, and slows the release of such compounds to the surrounding medium.  Highly volatile liquids are protected against losses by evaporation.  Encapsulation also provides protection against decomposition from exposure to ultraviolet light.
