RECENT PATENTS IN URUGUAY. 



.•According to a consular report, under date of March 21, 1919, 

 the Ministry of Industries, Uruguay, granted patents on the 

 following: improvements in suspenders; a substance known as 

 "Tamponina" for the prevention and repair of punctures in tires ; 

 and a tire for vehicles. 



JAPANESE TO PROTECT TRADE- MARKS. 



It is reported that an association has been established at Osaka, 

 Japan, for the purpose of protecting Japanese trade-marks against 

 infringement, particularly in China where the subject matter of 

 trade-marks is not regulated. Japanese business houses have 

 suffered much by reason of the infringement of their trade- 

 marks in China. 



TRADE-MARKS IN URUGUAY. 



A consular report from Asuncion, Uruguay, advises manufac- 

 turers who have not registered their trade-marks in that country 

 to omit them on goods sent there, as it sometimes happens that 

 mdividuals in Uruguay register such marks to prevent competitors 

 from handling the line or for the purpose of exacting a premium 

 for the right to sell goods bearing such marks. 



PROTECTION OF TRADE-MARKS IN CHINA AND JAPAN. 



A consular report calls attention to the importance of ade- 

 quate protection of trade-marks in China. This may be accom- 

 plished by registering them with the customs officials in Shanghai 

 and Tientsin, after which the superintendents of customs issue 

 proclamations for their protection. Trade-marks should also be 

 registered in Japan to secure adequate protection there. 



HONDURAS HAS NEW TRADE-MARK LAW. 



A new trade-mark law enacted in Honduras, effective August 

 ', 1919, provides for a registration fee of $50 gold for each trade- 

 mark registered. This fee will not be required, however, on 

 applications filed prior to that date. 



METHOD OF DETERMINING TON-MILEAGE OF TRUCKS. 



Asi.Mi'i.E .^.N'u ACCUR.\TK METHOD for figuring the ton-mileage of 

 motor trucks is described by The B. F. Goodrich Rubber Co. 

 Before arriving at the cost of truck operation it is essential to 

 have the ton-mile figure for comparison with the average daily 

 cost of operation. Such a system will allow the owner to com- 

 pare the operating cost of one make of truck with another, and 

 as well, truck haulage with horse and wagon delivery. 



There are two classes of units used for measuring truck 

 haulage. One is the absolute ton-mile, while the other is the 

 commercial ton-mile. They should not be confused. 



The absolute ton-mile is similar to that used in figuring rail- 

 road freight mileage. Because of the various systems of deliv- 

 ery, contingent on jtops and loads to be dropped en route, what 

 is called the commercial ton-mile is adopted as a standard of 

 measurement. The absolute or railroad ton-mile is one ton 

 carried one mile ; thus, one ton carried five miles equals five 

 ton-miles, and five tons carried one mile also equals five ton- 

 miles. Similarly, five tons carried three miles makes fifteen ton- 

 miles. 



.Absolute ton-miles should be figured in connection with motor 

 truck haulage only when uniform hauls are made, that is, when 

 one truck carries the same load over the same distance. By 

 multiplying the number of miles covered by the number of tons 

 carried the owner can easily determine the cost per ton-mile 

 by the additional operation of dividing the average daily ton- 

 mileage into the average daily cost of operation. The result 

 will be the cost per ton-mile. These figures are indispensable in 

 keeping an accurate account of delivery expense and profit. 



The commercial ton-mile is figured for trucks employed in 

 continually making deliveries of portions of their loads. The 

 big majority of trucks are operated under this condition. It 

 can readily be seen that absolute ton-mileage would necessitate 

 separate figuring for each stop and would be decidedly im- 

 practicable. Hence, the commercial ton-mile used. 



The information from which to figure the commercial ton- 

 mile comes from the driver's card. All that is needed is the 

 number of deliveries made, the weight of each load and the 

 total mileage for the day. First, determine the average tons per 

 trip. This is found by reducing the total number of pounds 

 hauled to terms of tons, i. e., 12,000 pounds would be termed as 

 6 tons. The average tons per trip, or the average load, is 

 found by dividing the number of tons hauled by the number of 

 deliveries made, i. e., 6 (tons) divided by 5 (deliveries) equals 

 one and one-fifth tons, or the average load. This result multi- 

 pHed by the total mileage for the day gives the ton-miles. For 

 example, if the mileage covered by the truck is 60, the ton- 

 miles for the day amount to 72, or 60 times one and one-fifth. 

 When the truck makes but one trip a day, multiply the mileage 

 by the number of miles carried, thereby using the absolute ton- 

 mile basis. 



Ton-miles are nothing more than the units for measuring truck 

 performance. The principle of ton-mileage may be applied to 

 any class of motor-truck haulage whether the units are baskets, 

 bundles, kegs, cases, or thousands of feet of lumber. For the 

 concern which does not do its hauling in tons the same measure 

 of haulage may be had by substituting for the ton the unit best 

 served to measure the delivery system. Thus, instead of the ton- 

 mile we have the package-mile, multiplying the number of 

 packages delivered by the number of miles covered in delivering 

 them, or the keg-mile, or the case mile. 



INTERCONTINENTAL CLOSES TORREON FACTORY. 



The directors of the Intercontinental Rubber Co. have decided 

 to close the factory at Torreon, Mexico, for an indefinite period, 

 owing to the low price of crude rubber and present conditions in 

 Mexico.
