Abstract: LIQUID HERBICIDAL COMPOSITION HAVING EXTENDED PENETRATING AND SYSTEMIC ACTIVITY            Abstract of the Disclosure A liquid herbicidal composition is dis-closed which retains its penetrating and systemic activity after application to susceptible flora under normal ambient conditions for a period of at least six hours by combining at least two different salts of at least one herbicidally active compound and a polyhydric alcohol.  The salts are preferably amine, ammonium or alkali metal salts of herbicidally active acidic compounds which are halogenated carboxylic acids, aromatic carboxylic acids and the halogenated aromatic carboxylic acids and particularly deriva-tives of phenoxy acids or benzoic acids, organic arsenic acids as well as halogenated aliphatic car-boxylic acids.  The polyhydric alcohol is preferably a polyhydric diol having 2 to 6 carbon atoms or glycerol.   Chelating and dispersing agents may also be  included in the formulation.   The herbicidal composition upon application to noxious vegetation has the unexpected property of retaining its phyto-toxic activity throughout the maximum residence time necessary for effective weed and brush control by virtue of the fact that the composition not only resists crystallization but also displays no tendency throughout such maximum exposure time to either burn or otherwise damage the external cellular layers of the plant being treated which would impede active agent penetration into the plant, or reversion to acid form that could produce outer cellular layer burn or scaling with the same detrimental effect on penetration of the herbicide and systemic activity.

Abstract: DOCKET   E4289.04 FLOTATION BAG ASSEMBLY     ABSTRACT     An apparatus for the stable support of a structure, such as an antenna, in a fluid medium, such as the ocean.   A flotation bag supporting an antenna is stabilized by the following features, which can be used individually or in combination.  A partially submerged ribbon fence supported by a submerged damper skirt dissipates the kinetic energy of the flotation bag caused by the movement of the ocean and water that encroaches upon the bag.  A flexible connection between the bag and the payload enables the bag and the payload to undergo limited motion without affecting each other. Thus, the bag's motion is decoupled and totally independent of the payload.  The housing which supports the payload has a flooded chamber, lowering the center of mass of the apparatus.  The bottom of the flotation bag is inwardly arched, moving the bouyancy away from the center of the bottom of the bag, enhancing stability and allowing the bag to float lower in the ocean, keeping the damper skirt submerged.  The payload includes an r.f. signal source.  The apparatus is designed to constrain the motion of the antenna to within very narrow operational limits.
