A process for poly(ester-carbonates) from dihydric phenols, especially bisphenol A; aromatic or cycloaliphatic dicarboxylic acids, especially terephthalic acid; and phosgene as carbonate precursor wherein a reaction of the acid and phosgene is carried out in a first stage forming dicarboxylic acid c ...

Mandayam C Narasimhan: Continuous casting method for metallic strips. Allied Chemical Corporation, Gerhard H Fuchs, March 6, 1979: US04142571 (139 worldwide citation)

Continuous metal strips are formed by forcing molten metal onto the surface of a moving chill body under pressure through a slotted nozzle located in close proximity to the surface of the chill body. Critical selection of nozzle dimensions, velocity of movement of the chill body surface, and gap bet ...

Leon Segal: Stampable thermoplastic sheet reinforced with multilength fiber. Allied Chemical Corporation, Roger H Criss, P Henry, August 23, 1977: US04044188 (101 worldwide citation)

Reinforced thermoplastic polymer composite sheets are formable into smooth, shaped objects in a rapid stamping process in a cool mold when pre-heated outside of the mold. The characterizing constituents of the composite sheet are: (1) thermoplastic resin, (2) relatively short reinforcing fibers, (3) ...

Ranjan Ray: Amorphous alloys which include iron group elements and boron. Allied Chemical Corporation, David W Collins, January 10, 1978: US04067732 (100 worldwide citation)

Iron group-boron base amorphous alloys have improved ultimate tensile strength and hardness and do not embrittle when heat treated at temperatures employed in subsequent processing steps, as compared with prior art amorphous alloys. The alloys have the formula

Frederick P Chlanda, Lester T C Lee, Kang Jen Liu: Bipolar membranes and method of making same. Allied Chemical Corporation, Arthur J Plantamura, Ernest A Polin, Thomas D Hoffman, September 26, 1978: US04116889 (90 worldwide citation)

Stable bipolar membranes of high permselectivity and low potential drop are prepared using either an anion or cation preformed first layer upon which a second layer or coating of an ion exchange resin of the opposite charge carried in a matrix polymer is applied. The second layer may be suitably app ...

Lester T C Lee, Win Sow Ho, Kang Jen Liu: Membrane solvent extraction. Allied Chemical Corporation, Arthur J Plantamura, May 11, 1976: US03956112 (84 worldwide citation)

A membrane solvent extraction system is utilized to separate two substantially immiscible liquids and extract a solute through a solvent swollen membrane from one solvent liquid phase to the extracting solvent liquid without direct contact between the liquid phases. The membrane extraction method ha ...
