Mobile Crushing Machines in Quarry

A process for pre-emergence weed control in agricultural crops which comprises applying to a locus to be protected an herbicidally effective amount of ethyl N,N-dipropylthiolcarbamate mixed together with an herbicidally eltective amount of at least one s-triaziue selected from the formula:where:where X is selected from the group consisting of chlorine,methoxy, and methylthio,mobile crusher for sale,R and R are selected from the group consisting of alkyl radicals containing less then four carbon atoms, and the radical -(CH OCH and n is an integer selected from the group consisting of 2 and 3.An herbicidal composition comprising a mixture of an herbicidally efiective amount of ethyl N,N-dipropylthiolcarbamate with an herbicidally effective amount of at least one s-triazine selected from the formula:

Field of the Invention .This invention relates to abrasion resistant gas generating compositions and a method for their manufacture. More particularly, this invention relates to abrasion resistant gas generating compositions in granular form for inflating passenger vehicle crash bags. While the present compositions are particularly useful in the inflation of passenger protective crash bags in passenger vehicles, it can readily be seen that the compositions may be used in the inflation of other inflatable devices as for example, inflatable boats, rafts, escape ladders etc.

Description of the Prior Art .The concept of utilizing an inflatable bag or envelope to protect passengers traveling in vehicles such as automobiles, boats, and aircraft during a collision or crash is generally known in the art. Such crash bags which are known in the art and which may be utilized in the practice of this invention are disclosed in U.S. Pat. Nos. 2,834,609, 3,117,424, 3,336,045, 3,450,414, and 3,573,885.
