Separate Refining Versus Mixed Refining Of An “Easy” And “Hard” Refining Pulp, Richard M. Dennany

Paper Engineering Senior Theses

A study of the strength development (mullen and tear) of mixtures of "easy" and "hard" refining pulp, in which the pulps were refined as a mixture with that in which they were separately refined, and then mixed, reveals that separate refining develops mullen to the same extent as does mixed refining, but that a higher tearing resistance at the same freeness and mullen can be obtained with separate refining.

Utilization Of Deinking Waste, Richard H. Jones

Paper Engineering Senior Theses

Introduction

In research aimed at utilization of sludge obtained from primary sedimentation of deinking mill wastes a literature study was made to determine what has been done toward meeting these ends and what new lines of thought needed investigation.

Our first thought in a literature survey was to find out the nature of the deinking sludge. It was found that the composition of deinking solid varies greatly from mill to mill and is determined by the waste paper used. A commercial laboratory analysis showed that the sludge is principally clay and fiberous materials (Table I) (1).

A early as 1931 …

Study Of Some Factors Which Influence Froth Flotation Of Deinked Stock, Peter C. Longjohn

Paper Engineering Senior Theses

Mineral and fiber were concurrently reclaimed from coated waste stock with the froth flotation process. Percentages of ash and fiber reclaimed are included along with the brightness of the deinked stock.

A suitable cooking formula and two flotation systems were discovered which respond favorably to froth flotation and yield a relatively high brightness before bleaching.

Printing Quality As Determined By The I.G.T. Tester, William A. Pritchett Jr.

Paper Engineering Senior Theses

Investigation of this method for the determination of printability indicates that it can be used to predict the printability of paper. However, since it lacks numerical rating, the visual evaluation depends finally upon the personal judgment of the investigator.

An Analysis Of The Articulation Errors In Spontaneous Speech Of One Hundred Children With Lisps, Paula C. Downs

Masters Theses

The Problem

This study is an attempt to determine the nature and relative frequency of the articulation errors shown by one hundred school children with lisps.

The Importance of Investigating the Phenomenon of Defective Articulation

The incidence of speech defects in the child population has been found to range from five percent (5%) to ten percent (10%) of the total child population. A child's speech is considered defective when the listener gives as much or more attention to the manner in which the child speaks as he does to the idea being communicated.

A Study Of The Effects Of Delayed Side-Tone Upon Voiced And Whispered Reading Time, Bruce Presten Ryan

Masters Theses

Definition of Delayed Side-Tone

The term delayed side-tone feedback refers to the delaying of one's hearing of himself by a fraction of a second, so that instead of hearing himself as he normally does, he hears himself or his own speech a fraction of a second later.

...in order to produce delayed speech feedback it is necessary to return the speaker's speech to his own ears approximately one-means of a magnetic tape recording and reproducing machine which has used to experience the effect prominently since they deliver delayed speech and exclude the normal air-borne undelayed speech sound which provides the …

Brush Finishing Of Coated Paperboard, Arlon F. King

Paper Engineering Senior Theses

Introduction

It would seem apparent that a brief explanation of the term "brush finishing of paper" is in order before dealing extensively with our literature survey. Although brush finishing is not a new term, it has never been dealt with in its true sense as a means of finishing paper in the paper industry.

Brush-enamel papers were developed and used extensively in the second half of the 19th century and early part of the 20th century. The new development came from Germany and as the art of paper coating had been developed there to a high degree, the brush-polishing process …

The Effect Of Recorded Stuttering On Listener Compression, Harold Walter William Homann

Masters Theses

Chapter I.

The Problem

Justification of this research. This experiment was designed to test the prevalent opinion that poor speaking reduces comprehension. Typical of such opinions is the conclusion of Knower, Phillips, and Koeppel¹, who state:

"The comparative effectiveness of speaking and oral reading as methods of presenting material depends upon the quality of performance. Poor speaking seems to be the least effective method of presenting informative materials. There is a direct relationship between the quality of speaking performance and the amount of material recalled. Poor speakers produced least recall."

Of the many factors which contribute to effective …

The Effects Of Manifest Anxiety On Stuttering Adaptation, Joseph Agnello

Masters Theses

I. Introduction

When stuttering behavior is viewed as a problem in learning, the phenomenon of adaptation frequently receives attention. A standard adaptation experiment consists of having the person who stutters re-read the same passage, or a passage of equal difficulty, a specified number of times. Under these conditions a relative reduction¹ in stuttering frequency usually occurs. Experimentalists and clinicians alike have long been puzzled as to why this decrement takes place, since stuttering is generally considered by many writers^2,3 as a self-reinforcing disorder; that is, stuttering produces more stuttering.

The present experiment was designed to investigate the effects, …

A Comparison Of Coated Paper Surfaces By Photomicrography, Everett L. Potts Jr.

Paper Engineering Senior Theses

Five different types of coated papers were photomicrographed, namely cast coated, roll coated, trailing blade coated, air brush coated, and brush coated grades.

All cast coated papers were found to be extremely smooth and essentially free of pattern.

Roll coated papers displayed a microscopic pattern which resembled the magnified surface of an orange peel.

Trailing blade coated papers displayed sharp-edged pits and, in some cases, scuffed surfaces.

Air brush coated papers had a microscopic pattern which resembled the non-magnified surface of a pie crust.

Brush coated papers closely resembled air brush coated papers microscopically, however, they also carried a macroscopic …

A Survey Of Management Opinions Of Noise In The Pulp And Paper Industry, Carola Trittin

Masters Theses

Introduction

The pulp and paper industry is the fifth largest in the United States, dollar-wise, and is also the third fastest growing industry in the United States (1). There are between 375,000 and 400,000 people employed directly in the pulp and paper mills in the United States and Canada. A nation-wide survey on the importance of noise in this industry is needed to help clarify the effects, if any, that noise has upon its employees.

By definition, noise is non-harmonious sound. When the subject of noise is mentioned, many suggestions are given on places where such a study should be …

The Analysis And Evaluation Of Supervisory And Managerial Personnel, Robert A. Huston

Masters Theses

Introduction

The rapid growth of American industry during the first half of the Twentieth Century has brought managements face to face with the necessity to delegate responsibility and commensurate authority to the various echelons of the supervisory and managerial personnel. The owner-manager era is a thing of the past. Gone with it is the intimate relationship that once existed between the owner of the business and those who worked for him. In its place has arisen the corporation, a statutory entity that cloaked ownership with impersonality.

Coincidental with the change of character of ownership and, indeed, one of the major …

A Study Of Cholesterol And Lecithin Blood Levels In Rh Sensitized Women Treated With Rh Hapten, Franklyn Lewis

Masters Theses

The Problem And Its Background

Introduction

Perhaps one of the most popular subjects, and a subject which has been discussed a great deal by the layman is that of Rh and Rh incompatibilities.

Landsteiner¹ discovered the Rh property of human blood by means of immune sera prepared with the blood of rhesus monkeys. He was assisted in this work by Wiener², who states that the Rh property was found to be present in about 85% of white individuals, and independent of the blood groups and M-N type. It is these individuals who are referred to as Rh …

The Influence Of Clay Flocculation And Dispersion On The Covering Power Of Clay Coating Colors, Donald G. Pryor

Paper Engineering Senior Theses

Introduction

A survey of the literature showed that considerable information has been published on the effects of dispersing agents on the viscosity of coating colors and clay slurries. There seemed to be little work done on the effect of the dispersing agent on any other of the properties of the coating.

The Evaluation Of The Printability Of Papers By The I.G.T. Method, Robert W. Shaw

Paper Engineering Senior Theses

Introduction

The purpose of this investigation was to determine to what extent the I.G.T. Tester could be used to determine the printability of paper. The investigation was carried out along two related paths. First to determine if the I.G.T. Tester could be used to give indications of actual press printability and secondly to determine if the results of the I.G.T. Tester were reproducible.

Some Effects In Chlorine Dioxide Purification Of Kraft Softwood Cellulose, Maynard C. Nieboer

Paper Engineering Senior Theses

Introduction

Up until the middle thirties, chlorine dioxide had been considered an expensive bleaching agent and also had been too explosive to ship as a gas, so it had remained a laboratory curiosity since its discovery in the 19th century. In the middle thirties, Mathieson Chemical Corporation found that solid sodium chlorite was a cheap and effective carrier of chlorine dioxide. This discovery opened the door for extensive use of chlorine dioxide and since then it has come into its own as a bleaching agent. This investigation is concerned with the three methods of generation of chlorine dioxide from sodium …
