    Fireproofing of polymers with derivatives of phosphines and with halogen-phosphorus compounds (1964)
    Stamford, Conn. [u.a.] : Wiley-Blackwell
    Polymer Engineering and Science 4 (1964), S. 45-55 
    Details
    ISSN: 0032-3888
    Keywords: Chemistry ; Chemical Engineering
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Physics
    Notes: Chemical structures limited to phosphines and their derivatives, including phosphine oxides, phosphonium salts and halogen-phosphorus compounds useful for fireproofing are discussed. In addition to these P-C bond containing compounds, structures containing P-O-C bonds are mentioned only if they are directly formed from halophosphorus substances. The general approaches to fireproofing are described. They include physical changes, unreactive additives, reactive comonomers, substitution of other functional groups and addition to a preformed polymer. Much of the literature is reviewed and the commercial importance of certain methods for both cloth and plastics are indicated.

    Polymer Engineering and Science 2 (1962), S. 294-297 
    Details
    ISSN: 0032-3888
    Keywords: Chemistry ; Chemical Engineering

    Notes: Polymerization of the monomer was investigated in organic solvents such as nitro-compounds, amines, amides, nitriles, ethers, esters, ketones, aldehydes, acids, anhydrides, and some heterocyclic compounds. Crystalline polyvinylchloride was produced in aliphatic aldehyde media at temperatures ranging from 0° to 60°C and highly crystalline polyvinylchloride was synthesized in the presence of preliminarily oxidized butyric aldehyde. The electron diffraction picture of the non-oriented specimen of the polymer exhibited 19 distinct reflexes.

    Moldability of plastics based on melt rheology. Part II - practical applications (1963)
    Stamford, Conn. [u.a.] : Wiley-Blackwell
    Polymer Engineering and Science 3 (1963), S. 37-41 
    Details
    ISSN: 0032-3888
    Keywords: Chemistry ; Chemical Engineering
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Physics
    Notes: An expression for the “average” viscosity of a polymeric material realized during an injection molding shot is developed. From this expression certain rheological quantities are taken which should better express ease of molding than do conventional testing methods. Comparison is made between actual molding experience and quality as predicted by the new method.

    Tensile impact properties of thermoplastics (1964)
    Stamford, Conn. [u.a.] : Wiley-Blackwell
    Polymer Engineering and Science 4 (1964), S. 25-28 
    Details
    ISSN: 0032-3888
    Keywords: Chemistry ; Chemical Engineering

    Notes: The impact strength of a thermoplastic is shown to be a strong function of several variables. Among these are type of molding, molding conditions, molecular orientation, test temperature, and notches. Particularly significant is a maximum in the response of impact strength to molding temperature. The tensile impact test was used as a tool for these determinations.

    An experimental study of liquid-phase turbulent diffusion: Part I. Fluid mechanical data (1962)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 8 (1962), S. 103-108

    Notes: Results from an investigation of the fully developed turbulent wake of a circular cylinder are presented. The study was conducted in the liquid phase, in the controlled flow field of a water tunnel. A technique was developed for measuring the intensity of turbulence in water. The decay of turbulence intensity downstream from a series of fine-mesh wire screens was measured and compared with aerodynamic decay laws. Profiles of the turbulence intensity in the cylinder wake were also obtained. This paper is Part I of a study of liquid phase turbulent mass transfer in the wake of a cylinder. The mass transfer results are reported in Part II.

    Calculation procedures for binary batch rectification (1960)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 6 (1960), S. 335-342 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: A rigorous mathematical description, consisting of differential-difference equations, is presented for binary batch rectification in the plate type of column. Two approaches are taken to solving these equations for the condition of constant reflux ratio: an integration by numerical means employing an IBM 650 computer, and a hand calculation procedure that involves trial-and-error computation of batch-rectification curves, which is of interest primarily where high-speed computing equipment is not available.Enthalpy balances are used to avoid assumption of equal rate of overflow in the tower; weight units are used instead of mole units; means for accounting for holdup in the condenser-accumulator system are described. Criteria of convergence and stability of the numerical solution are presented. The validity of the results of the proposed calculation procedures is substantiated by the close agreement of experimental and calculated batch-rectification curves.

    An experimental study of liquid-phase turbulent diffusion: Part II. Calculation of local turbulent mass transfer coefficients in the turbulent wake of a cylinder (1962)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 8 (1962), S. 108-112 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering
    Source: Wiley InterScience Backfile Collection 1832-2000

    Notes: Turbulent mass-transfer coefficients were calculated from concentration profiles obtained in the wake of a hollow cylinder having a porous wall through which a solution of electrolyte was flowing. These coefficients are presented as functions of the turbulence intensity and the width of the transport region. This paper is a continuation of the previous report on this subject and utilizes the results presented earlier.

    On the steady state activity levels in a reactor-regenerator system (1960)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 6 (1960), S. 488-493 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: A method is proposed for computing the steady state activity levels at various points within a reactor-regenerator system in which the residence time distribution functions in the reactor and regenerator, the permanent deactivation function, and the temporary deactivation and activation functions are arbitrarily specified. A particularly simple solution to these equations is obtained when the temporary activation and deactivation functions are of exponential form. The latter equations are used to calculate values of the mean activity in the reactor for the limiting cases of piston type of flow and complete mixing under a variety of conditions.
