Abstract: A Bayard-Alpert gas pressure measuring gauge with x-ray effect neutralization comprising collector and shield electrodes that comprise the same substantially inert electrically conductive substances. Said inert substance may be gold or another substance from the group consisting of platinum and rhodium, and mixtures thereof, and alloys comprising gold, platinum or rhodium; or said substance may be selected from the group consisting of the oxides of indium, chromium, vanadium and tin, mixtures thereof, and alloys comprising one of these. An electrical potential is applied to the shield that is more negative than the potential applied to the collector, said potential on the shield being in the range from about zero volts to about −50 volts when the collector is operated at a positive potential. Said negative potential with respect to the collector enhances the reverse x-ray effect for cancellation of the forward x-ray effect in the gauge.

Abstract: What is described is an aqueous, flowable suspension concentrate of an agriculturally active chemical having excellent dilution and storage stability, and sprayable aqueous use formulation thereof, containing partially neutralized alkyl vinyl ether-maleic acid half-ester copolymers as dispersing agents therein.

Abstract: This invention relates to a composition containing an active chemical and a particulate polysaccharide matrix having improved water dispersibility and dispersion stability in aqueous solutions by the incorporation of a copolymer of a N-vinyl lactam monomer and a hydrophobic comonomer. The improved properties of the matrix promotes its use as a dispersing agent in a wide variety of formulations where soil and skin substantivity or sustained release of the active chemical is required, as in pharmaceutical, pre- and post-emergent agrochemical and cosmetic formulations. The invention also pertains to the preparation and use of formulations based on the use of polysaccharide/copolymer matrix of this invention.

Abstract: An effective emulsifiable concentrate for a low dosage fluorinated agricultural chemical, e.g. diflufenican, a herbicide, in optional admixture with a diluent active agricultural chemical, e.g. bromoxynil octanoate or isooctylmetachlorophenyl acetate herbicides is described herein.

Abstract: Stable, water-based formulations containing high levels of water insoluble UV protectants/insecticides are provided herein as sprayable microemulsions containing a film-forming polymer, e.g. Agrimer.RTM. VEMA ES 425 [poly(methyl vinyl ether-maleic acid monobutyl ester)]. The polymers are solubilized either by partial neutralization with a base, or by emulsification with appropriate emulsifiers. These formulations produce single phase, micro- or mini-emulsions (particle size<1 micron) on dilution with water. The formulations are useful as UV protectants in veterinary use, for protection of UV-labile insecticides, and for "pour on" applications.

Abstract: Gating apparatus for a static crossed field photomultiplier utilizes a gating electrode which is mounted in a position between the cathode and the rail electrode. The gating electrode is pulsed thus causing the cathode current to be either multiplied or diverted so as to modulate the current by shifting the cathode beam into and out of the dynode area where secondary amplification occurs.
