and is closed by a fluid-pressure cylinder, the piston of which 

 is connected to the door by a flexible mcmljer B. 



The ingredients to be mixed with the rubber are contained 

 in a drum, mounted on rcvoluble members indicated by C in the 

 recess of the door. In use, a filled drum is placed in position and 

 the door closed. When the pigments are to be introduced into the 

 mixing chamber, tjie ends of the drum are removed and the 

 contents allowed to pass into the cliamber. The eccentric mount- 

 ing of the drum assists in shaking out the material. — British 

 patent No. 150,269.— .A. P. Lohmann, .\kron, Ohio. 



APPARATUS FOR RECOVERING VOLATILE SOLVENTS 



This machine is shown in Fig. 3, in greatly reduced proportions. 

 The rubber material under treatment is covered with a closely 

 fitting hood, through which air is drawn. The air within the 

 hood is agitated by a fan in order to improve its evaporating 

 efiiciency, and then passes to a condenser. The hood .4, in which 

 the fan is mounted, has a counterpoise, so that it can be easily 

 raised. The air is withdrawn through a flexible tube B pro- 

 vided with a cut-oflf valve connected to the starting lever of the 

 machine. The air passing through the hood A to the condenser 

 C may be compressed. The condenser tubes may be of circular 

 cross section provided w'ith hexagonal baffles, on a central rod, 

 to collect the liquid.— British patent No. 141,210.— D. V. 

 Plumbridge, Holmewood, South Kilworth, Warwickshire, Eng- 

 land.

LUBRICATING TIRE MOLDS 

 A very convenient and satisfactory means of lubricating tire 

 repair or other rubber molds is by means of a pad of cheese-cloth 

 which has been well-saturated with melted cocoa butter and 

 replaced with a fresh pad at frequent intervals.
