Using an Electric Heater to Dry 

 the Glue on Envelopes 



ENVELOPE making today is an excep- 

 tionally rapid process in which a single 

 machine neatly cuts the paper stock, folds 

 and glues the envelopes, and then carries 

 these on a conveyor to the boxes waiting for 

 them. In dry weather this process goes on 

 uninterruptedly; the glue dries in the time 

 it takes the machine to fold the envelope 

 flaps back. In rainy weather, however, the 

 process does not go on so smoothly. The 

 glue does not dry quickly enough a nd hun- 

 dreds of new envelopes are com 

 pletely sealed and therefore 

 wasted. - 



A manufacturer in 

 Chicago, 111., places 

 a simple electric 

 heater under the 

 conveyors of his 

 machines. On very 

 damp days a heavy 

 current is sent 

 through the resis- 

 tances of the heater, and 

 the hot air currents set up 

 quickly dry the glue. The 

 strength of the current de- 

 pends upon the dampness.

How to Store Flour to Prevent 

 It from Molding 



SPECIALISTS in the United States 

 Department of Agriculture have 

 studied the best means of storing flour 

 in the home so that it will not be con- 

 taminated by odors or become musty. 

 Flour should never be stored in the 

 cellar even though a bin has been 

 built in the cellar for that purpose. A 

 cellar is usually damp and odors are 

 generally found there which the flour 

 will absorb. The attic is as bad a 

 place to store flour as the cellar. In 

 the summer the temperature of the 

 attic is too high and as the venti- 

 lation is usually poor the flour is 

 likely to acquire a musty odor. Ex- 

 cept in very small 

 quantitiesflourshould 

 not be stored in the 

 pantry or kitchen be- 

 cause the tempera- 

 ture is too uneven 

 and there are too 

 many odors which the 

 flour is likely to ac- 

 quire. Every house should possess a 

 small, well ventilated store room where non- 

 odorous food should be kept. The temper- 

 ature in this room should be so regulated 

 that it will not fluctuate more than a very 

 few degrees. Always clean the flour con- 

 tainer before putting in new stock. If 

 flour is kept in the barrel in which it was 

 purchased, boards should be placed under 

 it to keep it off the floor.

YES, they get wrinkled in a drawer,

 But here's a solution. 

 A Florida inven-

 men's ties that is 

 proving satisfactory. 

 The device consists simply 

 of several leaves, between 

 which the ties are placed.
