Worldview Integration: • God wants us to read, circulate, and explain his Word to others. (Acts 8:26-40; letters of Paul) • God is the maker of the heavens and the Earth. (Genesis 1:1). • God gave us the stars and constellations to help us navigate here on Earth. (Matthew 2:1-12).

One was the application of an ancient tool called the astrolabe—a compact instrument used to observe sun, moon, stars, and other celestial bodies. The other was the invention of the printing press by Johannes (John) Gutenberg. He figured out the use of movable type. Because of the printing press and the travel journals of the explorers, people across Europe were able to read about a new world and its potential for trade and wealth to Europeans.

Preface Tms SECOND EDITION of the Maintenance Check List is compiled to provide a quick ready reference of common ills and cures of linecasting machinery. It also includes care and adjustments of the machines as recommended by the Mergenthaler Linotype Company. There has been no attempt to make this book difficult by introducing subjects beyond the scope common to all machines. On the contrary, the end in mind is that the work be a useful tool to any man with casual ma­ chine knowledge who desires to solve his own problems. It is interesting to speculate on how much money is paid out each year by shop owners to have high priced machinists come in to correct problems that they could well solve themselves, given something to work with. It is hoped that to these men the book will provide a convenient, practical source of help and information. As in all such works as this, much has been left un­ said. Time and money are, of course, prohibitive factors and a neces~ity for selection was inevitable. Any sug­ gestions for future inclusions, comments, or criticisms will be appreciated by the author.

  • Properties of Lead-Bismuth, Lead-Tin, Type Metal, and Fusible Alloys
    RP248 PROPERTIES OF LEAD-BISMUTH, LEAD-TIN, TYPE METAL, AND FUSIBLE ALLOYS By J. G. Thompson ABSTRACT The tensile strength, hardness, and elongation of a number of lead alloys have been determined and are presented herewith. Data on the solidification charac- teristics and on the resistance to compression of some of the alloys also are presented. The alloys studied are divided into four classes: (1) Binary alloys of lead and bismuth, (2) binary alloys of lead and tin, (3) type metals, with and without the addition of small amounts of bismuth, and (4) fusible alloys of bismuth, lead, tin, and cadmium. The data are presented both in tabular form and in graphs. CONTENTS Page I. Introduction 1085 II. Lead-bismuth alloys 1086 1. Methods of test 1087 2. Discussion of results 1087 3. Summary 1090 III.

INTRODUCTION In the course of an investigation seeking to develop and extend uses for metallic bismuth and its alloys, conducted at the bureau under the research associate plan in cooperation with the Cerro de Pasco Copper Corporation, the mechanical properties of a number of lead- base alloys were determined. These alloys included lead-bismuth alloys, solders, and type metals with and without additions of bis- muth, low-melting alloys, and some miscellaneous alloys.

The general supervision and control of the investigation was placed by the Joint Council in the hands of Dr. Frederick L. Hoffman. The Bureau of Labor Statistics was, from the start, called into these conferences and subsequently agreed to do a definitely outlined part of the work involved in the general survey. Under the agree­ ment the Bureau of Labor Statistics was to conduct a branch of the work involving the employment of at least one field investigator. Mr. Swen Kj aer was assigned to this field work. The schedules and questionnaires had of course been jointly agreed upon by Doctor Hoffman and the Bureau of Labor Statistics. Special Agent Kjaer began his field work in October, 1922, completing it early in 1924. The present bulletin is the beginning of the publication, of the re­ sults of the joint survey of the hygiene of the printing trades made by the International Joint Conference Council of the Printing In­ dustry and the Bureau of Labor Statistics in cooperation.

Owing to shortness of time, some passages had to he omitted in the reading. THE visitor to the composing department of a printing office finds a number of operatives engaged upon a process that is, apparently, extremely monotonous and fatiguing. Standing before a pair of shallow wooden trays, known as cases, inclined desk-like, the compositor holds in his left hand what is called a composing-stick a little iron or brass frame, one side of which is movable, so that it may be adjusted to the required width of the page or column which the workman has to set up. The "copy" from which he works rests on the least-used part of the upper case. The practised compositor takes in several words at a glance provided the author writes an intelligible hand, which virtue is by no means universal. One by one, then, the compositor puts the letters of each word and sentence into his stick, securing each letter with the thumb of his left hand, which is, therefore continually travelling from the beginning to the end of the line.

" THE First. Second and Third Editions of The Letter-Press " Printer having being disposed of, and a new edition inquired for, I have much pleasure in introducing to the trade a Fourth Edition. Of the First, Second and Third Editions over 9,000 copies were printed and sold, a quantity that has far exceeded my most sanguine expectations. This great success I attribute to the flattering notices of the trade journals, and to their warm recommendations of the work. I have done my utmost to improve the present edition in all the departments on which it proposes to afford instruction, and I hope my endeavours have been sufficiently successful to merit the continued approval of the trade. The Colour Printing section has been carefully read, cor- rected, and added to by a gentleman of great experience, who is at present managing one of the principal colour printing establishments in London. He pointed out some errors in that section of my First Edition, and kindly volunteered his gratuitor.s " " services to make Colour Printing more useful, reliable, and valuable in this edition.
