  • Patent number: 9980485
    Abstract: A method for systemically mitigating environmental stress from heat or radiation on a fruit plant and the pre-harvested fruit thereof that comprises the steps of: preparing an agricultural composition wherein the composition comprises an ethylene oxide-propylene oxide block copolymer, a C1-C4 alkyl ether of ethylene oxide-propylene oxide block copolymer, and an alkyl polyglycoside; and intimately contacting root zone soil of soil containing a fruit plant with a bioefficaciously effective amount of the agricultural composition to systemically mitigate environmental stress on the plant and the pre-harvested fruit thereof from heat or radiation impacting the surface of the plant or fruit above the surface of the soil, whereby the agricultural composition is not substantially absorbed into the plant.

  • Patent number: 9480254
    Abstract: Systemic mitigation of the heat stress damage to plants and pre-harvest fruit caused by environmental stress on the plant and fruit is realized by applying to the root zone of the plant a bioefficaciously effective amount of a composition selected from the group consisting of ethylene oxide-propylene oxide block copolymer, alkyl ethers of ethylene oxide-propylene oxide block copolymer, alkyl polyglycoside, and combinations thereof.

  • Patent number: 7541386
    Abstract: Water repellent soil is treated with low concentrations of EO/PO block copolymer having an HLB value of less than or equal to 2; an average molecular weight of greater than 3,000; and a percent hydrophile of 10 in order to rapidly increase the wetting rate of the water repellent soil.

  • Patent number: 7399730
    Abstract: Improved plant growth is realized especially with turf grasses by using an enhanced plant growth medium prepared by adding a bioefficacious amount of C1-C4 alkyl ether of methyl oxirane-oxirane copolymer that, serendipitously reduces the water repellency of the medium.

  • Patent number: 5738623
    Abstract: This invention relates to the use of activated charcoal granule compositions which, when dry spread and "watered-in" to a site, reduces undesirable biological activity of deleterious organic compounds. When wet, these granules disperse very rapidly with a large dispersion area to original granule diameter ratio. The granules have high loadings of charcoal, i.e., from about 60 to about 95 weight percent and contain from about 5 to about 40 weight percent of a surfactant system which exhibits excellent dispersing; rewetting; and binding properties.

  • Patent number: 4893332
    Abstract: A low-powered remote sensor is achieved by capacitively isolating a long duration perpetual timer which is powered by removing inductively coupled AC power from telephone lines or other long lines. Three embodiments are described using this concept. The first embodiment is a remote utility sensor designed to periodically dial and transmit data to a central site via telephone lines and report its functionality on a periodic basis. The second embodiment of the remote utility sensor is used for reporting utility usage for common utilities such as gas meters, water meters, electric meters and water softeners on a periodic basis over telephone lines. The third embodiment is a remote utility sensor which continually records utility usage and can be read by a portable recording device through a remote cabled interface.

  • Patent number: 4691344
    Abstract: A data transmitter unit (22) for transmitting data over conventional telephone lines (26) from a remote location (24) to a central location (28). The data transmitter unit (22) derives its operational power supply from the telephone lines (26) to which it is interconnected, thereby doing away with the requirement for a separate power supply. The transmitter unit (22) includes ring detect circuitry (46) for detecting a ring signal on the telephone line (26). The ring detect circuitry (46) cooperates with the stand by power supply (38) charged by a charging circuit (36) to energize a logic module (44) and analog converter circuitry (40, 42) which is interconnected to sensors (30, 32). The logic module (44) controls operation of a tone generator (48) which transmits frequency signals representative of the input received from the sensors (30, 32) over the telephone lines (20, 26) to a central location (28).
