long overhead drum. The roll to be ground or buffed is mount- 

 ed in heavy bearing brackets above the center line of the bed, 

 and revolves in its own journals. Grinding wheels are arranged 

 on both sides of the roll in the carriage, and are traversed in 

 both directions along the face of the roll, while the latter is 

 revolved at a suitable speed. The overhead drum extend 

 full length of the machine, an.! is longer than the longest roll 

 liable to require grinding. The roll is revolved from the driv- 

 ing shaft through two universal joints, and provision is made to 

 compensate For the deflection of the roll so that a perfectly true 

 ■,ui face may be obtained. [Bertrams Limited, Sciennes, Edin-

A QUICK-ACTING VULCANIZING PRESS. 



THE accompanying drawing shows a somewhat unusual form 

 of vulcanizing press, designed '•■■■ Paul Beer, of Berlin, Ger- 

 many. Instead of the usual four steel columns, this press has two 

 columns .•/. at the rear, and a single column B, at the front. It 

 has two cylinders C and D, each of which is provided with gil 

 ranged to slide vertically on a guide attached to the column B. 

 The cylinders may be swung around this column as a pivot, and 

 may be raised or lowered by means of a piston E operating in 

 a hydraulic cylinder F. 



The articles to be vulcanized are placed in molds stacked upon 

 a plate (7 on a truck II. The truck is then run under the cyl- 

 inder D, which is open at the bottom and raised as shown. This 

 cylinder is lowered over the molds by means of the piston E, 

 and the plate G is clamped to it. The cylinder C in the press 

 is relieved from steam and hydraulic pressure, and both cyl- 

 inders are then swung around the column B until cylinder D is 

 brought into position in the press, and cylinder C is directly 

 over the truck. The molds containing the vulcanized goods 



press tlie molds against the head, only a short movement is 

 .ti v. For this, a circular, hydraulic ram / is employed. It 

 has two concentric movable rings which have wedge-shaped pro- 

 tections arranged so that the piston may be locked in its raised 

 position. This circular, hydraulic press operates independently 

 i,t the main ram K . 



The advai tage i laimi d for this type of press is that it can be 

 charged and emptied simultaneously, thus reducing labor and 

 economizing time. Also the ram and cylinder of the main 

 press can be made shorter than usual, since the press operates 

 •■ill, to compress the molds

are then released by unclamping the plate G, and the empty 

 cylinder is then raised by means of the piston II. While this 

 is being done the press is operated to compress the molds, and to 

 press the cylinder against the head / of the press. In order to 



CONTRABAND OF WAS. 



rding to National Chamber of Commerce Bulletins issued 

 in August Germany had agreed to follow the decision of the 

 London Conference of 1909 as to the articles absolutely and 

 conditionally contraband. Those articles conditionally contraband 

 are liable to capture only if shown to be destined for armed 

 forces or for government departments. The English regular 

 are practically the same as those of Germany, except that the 

 German list includes aeroplanes, etc., in the conditionally con- 

 traband list while England places them in the absolutely con 

 traband seeti.ni. 



I {tract from la-i "i London Conference 1909. 



Absolutely Contraband— Distinctively military clothing and 

 equipment Articles of camp equipment and their distinctive 

 component parts. Aeroplanes, airships, balloons and air craft of 

 all kinds and their distinctive component parts, together with 

 accessories and articles recognizable as intended for use in con- 

 nection with balloons and air craft. 



Conditionally ( 'ontrohaitd.— Clothing, fabrics for clothing and 

 boots and shoes, suitable for use in war; vehicles of all kinds, 

 available for use in war and their component parts; materials 

 for telegraphs, wireless telegraphs and telephones. 



FRENCH MOTOR CARS AND THE WAR. 



According to advices from France, the subsidy scheme which 

 has been carefully developed during the last six years is now 

 proving of benefit to the nation. Uniformity of speed, size, 

 carrying capacity, weight, tire and wheel dimensions have been 

 the principal points kept in view. 



There are said to be 70,000 motors with the French troops, 

 15.000 of which represent subsidized motor trucks, which went 

 automatically into the service on the declaration of war and 

 were immediately moved forward to the German frontier. 



Besides calling for the subsidized vehicles, the army authori- 

 ties have made large purchases of trucks of all kinds. There 

 is in fact a shortage of this class of vehicle in France. The 

 French Government assumed, on August 1, the control of the 

 De Dion-Bouton plant, the workmen all donning soldiers' uni 

 forms. 



HOW TO GET GERMAN GOODS TO AMERICA. 



It is pointed out in the German press that there arc perhaps 

 two possibilities of sending goods to America, via Holland 

 (Rotterdam) and via Denmark (Copenhagen). As soon as 

 normal conditions are to some extent restored, and negotia- 

 tions with the Dutch steam lines are formally concluded, 

 goods will be sent to the Dutch frontier (Bentheim), where 

 they will be taken care of by Dutch shipping agents for 

 shipment via Rotterdam to America. German insurance com- 

 panies decline the war risk, but it is suggested that Dutch un- 

 derwriters might undertake it.
