    • 851,223. Recording the How of oil from oilbearing strata. BELL, T. G., and BRUNINGA, J. H. July 15, 1957, No. 22370/57. Class 41 Apparatus for promoting the flow of petroleum oil or gas from an oilbearing strata 1, Fig. 1, to a well boring 2, comprises a positive electrode 5 in contact through an anode 4 with the oilbearing strata at a distance from the well, and a negative electrode 6, 7 in the strata adjacent the well, the electrodes being connected to a source of unidirectional electrical energy, which may be pulsated. Voltages up to 1000V may be used. It is stated that the electric current flowing through the strata breaks down the capillary force between the oil and sand &c., and promotes the flow of oil towards the cathode by electro-osmosis. The pulsed voltage is generated by a shaped cam and contact breaker 14, 15 by which pulses are of unequal duration. The cathode 7 may be surrounded by a perforated screw. In modifications, not shown, (1) An inner tube inserted in the main well bore may be the electrode and insulated from it, (2) A number of such well bores with negative electrodes associated therewith may be operated in turn from a single positive electrode at a distance of 1000 feet or more, using a rotary contact switch in the D.C. generator circuit, (3) the pulsating current may be generated by charging and discharging a capacitor, (4) the positive electrode may also be associated with a well bore, and the current periodically reversed between the two electrodes one at each well bore. Either well then serves as a delivery well.

    • An aqueous agrochemical composition and in particular an agrochemical concentrate comprises (a) a non-encapsulated aqueous solution or dispersion of an agrochemical and (b) a suspension in said aqueous solution or dispension of a microencapsulated liquid, water-insoluble, bioperformance-enhancing adjuvant for said agrochemical. The adjuvant suitably has little or no surfactant properties. The invention permits oil adjuvants such as “Turbocharge” and “Brij 92” to be built into agrochemical compositions with which they would normally be incompatible. With certain adjuvants reduced phytotoxicity may be observed.
    • 水性农药组合物,特别是农用化学浓缩物包括(a)非包封的农药的水溶液或分散体,和(b)所述水溶液中的悬浮液或微胶囊化液体,水不溶性生物质量增强佐剂 用于所述农药。 佐剂适宜地具有很少或没有表面活性剂性质。 本发明允许将油佐剂如“Turbocharge”和“Brij 92”制成农药组合物,它们通常与它们不相容。 使用某些佐剂可以观察到降低的植物毒性。
