Abstract: IMPROVED HEAT RESISTANT HIGH IMPACT POLYMER COMPOSITIONS          AND METHOD OF MAKING SAME     ABSTRACT OF THE DISCLOSURE  A styrenic copolymer composition having increased resistance to heat, markedly improved impact resistance and excellent processability for injection molding, extrusion, thermal formability and the like is made by the polymeriza-tion of a vinyl aromatic monomer and an ethylenically un-saturated dicarboxylic acid moiety in the presence of at least two different rubbery additives.  At least one, but not all of the rubbery additives consists of a copolymer of from 40 to 95% by weight of a vinyl aromatic monomer and 5 to 60% by weight of a conjugated diene monomer.  This admixture permits addition of up to about 40% or more by weight of the total product of the rubbery additives.  The properties achieved offer an attractive balance found only in higher priced engineering polymer materials. The poly-merization process is preferably continuous and of the free radical type.  It is significant that the process affords energy conservation, even though it is adapted to handling higher concentrations of rubbery additives than hitherto found possible.

Abstract: TITLE Coextruded Multilayer Cation Exchange Membranes ABSTRACT OF THE DISCLOSURE A process for the preparation of a multilayer cationic ion exchange membrane is disclosed.  At least two substantially incompatible melt-fabricable fluorinated polymers containing sulfonyl or carboxyl functional groups are heated to a temperature above the melting point of the polymers, brought into contact and coextruded into a composite film. The resulting composite film is cooled to a temperature below the melting point of each of the films and the functional groups of the polymers are converted to ionizable functional groups.  The resulting membrane is useful as an ion exchange membrane, especially in the production of chlorine and caustic.

Abstract: PROCESSING CIRCUIT FOR OPERATING ON      ELEMENTS OVER A GALOIS FIELD               ABSTRACT OF THE DISCLOSURE     An operating circuit operates on digital data words to form products or quotients of the quantities represented by the digital data words.  The data words are considered as elements  .alpha.i of a Galois field GF(2m) where each element is a power  .alpha.i of an irreducible root The data words are input into a conversion ROM which in response provides the corresponding exponents  i  as an output.  These exponents i, j are additively combined to form a sum (i + j) or difference (i - j), and this is applied to a reverse conversion ROM.  The latter then provides, as an output data word, an element  .alpha.i+j or ?-j which is the product or quotient, respectively, of the input data words.  A provision can be incorporated to compensate for division by a zero element.  This circuit finds favorable application in error correction of a transmitted or recorded digital signal.                             -i-

Abstract: TITLE                  A GAS-LIQUID CONTACTING APPARATUS     INVENTORS      Karl T. Chuang Allan E. Everatt ABSTRACT OF THE DISCLOSURE A gas-liquid contacting apparatus is provided having downcomers which are closed at their lower ends by perforated, inclined, liquid distributing, gas entry retarding, plates.  The downcomers each depend from a drainage opening bounded by a weir on a perforated, liquid frothing tray.  Alternate trays have central drainage openings and are interposed with trays having drainage openings adjacent opposite tray sides.  The trays have liquid frothing perforations across the whole of each tray including the area beneath each drainage opening.  The perforations beneath a drainage opening occupy an area per unit area of the drainage opening in the range 0 to 25% less than the perforations per unit area in the remainder of that tray.  The apparatus produces a frothing layer on the trays in which the perforated, inclined, liquid distributing, gas entry plates are immersed and which gives a good liquid flow distribution across the tray so that a high efficiency of contact between the gas and the liquid is achieved.  When the plates of the downcomers are at positions above the froth on the perforated plate immediately below then each plate extends substantially horizontally.  The perforated, inclined, liquid distributing, gas entry retarding, plates extend upwardly along an inclined path towards the direction of flow of frothed liquid across the tray immediately therebelow.

Abstract: PATENT APPLICATION of LOUIS R. FALCE      for METHOD OF FABRICATING   A DISPENSER CATHODE                           Abstract A dispenser cathode is fabricated by covering a reservoir of electron emitting material with a perforated metal foil having an appropriate pattern of pore-sized apertures thereon for providing uniform electron emission from the cathode surface. The electron emitting material is in the form of a pellet of barium oxide impregnated with a wax or resinous material to minimize chemical reduction of the barium oxide in air. The impregnated barium oxide pellet is sandwiched between the apertured foil and a support structure to which the foil is welded. During tube bake-out or subsequently during cathode activation, the wax or resinous material evaporates and barium oxide migrates through the apertures to cover the surface of the foil in a uniform manner.  The barium oxide pellet is obtained from the carbonate and is wax impregnated prior to assembly into the cathode.  Thus no carbonate is present at the tube bake out or cathode activa-tion stages, thereby avoiding the carburization of electron emitting metal surfaces.

Abstract: A FOLDING TABLE, WORKBENCH OR THE LIKE            ABSTRACT The structure of a folding table, workbench or the like is simplified and the product made sturdy by providing the folding of legs of the table such that the legs are pivoted in pairs about two distinct, parallel pivot axes, so that the table folds generally in a parallelogram fashion.  A brace member is disposed at each end of two beam sections, one for each pair of transversely adjacent legs. Each brace member is pivotable about an axis transverse to the first mentioned axes, from a position flush with the underside of the table or bench top to a protruding position engaging the respective transversely adjacent legs.  Due to the mutually transverse arrangement of the pivoting axes, the overall arrangement is sturdy, simple and relatively inexpensive.  Also disclosed is a modified design having a folding seat secured to the table or the like.
