"HOW TO KEEP INVENTION RECORDS." BV HARRY A. TOUL- 

 min. Jr., I. D., I.itt. D.. with introduction by James T. NewKn. a 

 former^ United States Commisioner of Patents. D. Appleton & Co., 

 New York City. Cloth, 85 pages, 5 by 8 inches. 



This little volume on the keeping of invention records is of 

 great value to inventors. The first part discusses the general 

 nature of industrial property and monopolies granted to protect 

 it. The second part presents a practical method of insuring the 

 recording of dates, and a linal chapter deals with methods of patent 

 investigation. Failure to keep adequate records of inventions and 

 their development and reduction to practice has often deprived 

 inventors of the fruits of their ideas and labor, and has cost 

 thousands of dollars in litigation that might have been avoided 

 had the inventor used some such recording system as outlined in 

 this volume.

 partment of Agriculture, to serve the convenience of anyone who

 book shows that the author has attained this object very suc- 

 cessfully. His work merits appreciation of chemists and students 

 alike for the concise and accurate definitions presented in the 

 book. 



NEW TRADE PUBLICATIONS 



THE Yarnall-Waring Co., Chestnut street, Philadelphia, 

 Pennsylvania, manufacturer of "Yarway" power plant devices, 

 has issued a leaflet describing the Yarway Junior seatless valve, 

 which has recently been developed to meet the need for a valve 

 that would stay tight under high pressure steam on turbine drips, 

 superheater drains, water columns, blow offs, etc. Copies of the 

 descriptive sheet will be sent free upon request to the maker. 



The Boonton Rubber Manufacturing Co., Boonton, New 

 Jersey, maker of molded material for electrical insulations and 

 for mechanical, chemical and other purposes, has issued a 48-page 

 booket, attractively bound in leather-colored pebbled cardboard 

 covers, embossed with the company's trade-mark and stamped and 

 bordered with brown. The subject matter treats of the company's 

 products, giving a brief but comprehensive classification of molded 

 material, useful data on molded insulation, etc. Especially beauti- 

 ful and in a class by themselves as illustrations of mechanical 

 processes, arc the eleven full-page half-tones of workmen at vari- 

 ous machines, enlarged from photographs to give the soft-focus 

 effect so familiar on the screen. The printing and presswurk of 

 the booklet are also to be commended. 



The Birmingham Iron Foundry, Derby, Connecticut, has 

 issued a large two-color illustrated catalog of its rubber mill 

 machinery, printed on heavy plate paper which clearly shows 

 every detail of the various machines. Besides several full-page 

 views of the plant and its interior, there are forty-seven full-page 

 illustrations of machines, reproduced from photographs, including 

 crackers, washers and sheeters, light and heavy duty tnills, re- 

 finers, two to four-roll calenders, embossing calenders, experi- 



mental machinery, presses, bias shears, tread-making machinery 

 and many others. 



The Birmingham Iron Foundry is one of the best-known in- 

 stitutions of its kind in this country, and its long experience 

 makes it an authority on rubber machinery. It is always willing 

 to make suggestions and is able to supply machinery for the 

 manufacture of tires and accessories, boots and shoes, soles and 

 heels, mechanical and molded goods, hard rubber goods, carriage 

 cloth and clothing, asbestos sheeting, etc. Besides the many 

 machines illustrated, the Birmingham company also produces hose- 

 making and cross-wrapping machines, duck slitters, fabric dryers, 

 gutta percha calenders and washers, mixing aprons, doubling 

 drums, etc. 



The catalog is substantially bound in heavy paper covers, and 

 is intended to serve as a bulletin to make it easier for clients to 

 prepare their inquiries. Full descriptions and prices of each spe- 

 cific machine will he sent upon request. 



Under the name, 'Tire Trade Journal and I'ulcaniscr & Tire 

 Driller," the first issue of these two combined periodicals appeared

 go publication, first issued in September, 1919, and merged it with

An address, "Making The 1921 Grade," delivered by George 

 M. Gr.\ham, vice-president of the Picrce-Arrow Motor Car Co., 

 Buffalo, New York, at the annual meeting of the Motor and 

 .\ccessory Manufacturers' Association, Hotel Biltmore, New 

 York, January 12, 1921, was an able survey of the national auto- 

 motive field, a careful analysis of conditions helpful and deterrent 

 to the progress of the motor vehicle industry, and a well-reasoned, 

 stimulating plea for greater optimism. Of especial interest to 

 the tire industry is the testimony he submits to prove that auto- 

 mobile production is still far from reaching the point of satura- 

 tion, and he prophesies that the country will shortly enter upon 

 an era of motor mileage that will soon equal the total now pro- 

 vided 'by all-rail and river transportation. 



CALENDARS 



Tyson Brothers, Inc., Woodbridge, New Jersey, maker of 

 rubber substitute and chemicals for the rubber industry, has 

 presented a very beautiful calendar bearing no advertisement 

 other than the company's name and trade mark inconspicuously 

 stamped beneath the silk cord hanger. The calendar bears a 

 hand-colored print after the original water color "Our Daily 

 Bread," by Edwin Lamasure, which shows a golden wheat-field 

 stretching back to a group of farm buildings set beneath fine old 

 green trees. It is a typical representation of the peace and plenty 

 that characterizes our great land, in spite of the business Hurries 

 and an.xieties that prevail at times in crowded centers. 



.A daily date calendar with tear-off leaves bearing extra large 

 size figures has been presented to the trade by the Stamford 

 Rubber Supply Co., Stamford, Connecticut, maker of rubber 

 factice. 



The Buffalo Foundry & Machine Co., Buffalo, New York, 

 maker of the "Bufiovak" line of special machinery, has sent out 

 a 1921 calendar pad, fitted with an adhesive strip at the back 

 to enable it to be fastened to the calendar presented by the 

 company last year. 



David Bridge & Co., Limited, Castleton, Manchester, England, 

 the well-known British engineers and rubber machinists, have 

 sent out an attractive calendar bearing a reproduction of a draw- 

 ing by W. Alister MacDonald of the Old Shambles, Market 

 Place, Manchester. Its quaint half-timbered houses with many- 

 gabled roofs and small-paned bow windows are reproduced in 

 soft colors.
