  • System and method for electronically signalling along a fence line
    Patent number: 6911900
    Abstract: A system for electronically signalling along a fence line, comprising one or more transmitter device(s) for connection to the fence line from which control signals or information may be sent along the fence line and one or more receiver device(s) for connection to the fence line to receive control signals. Each transmitter device includes transmission means arranged to form the control signal(s) or information as one or more data blocks, generate a carrier frequency, and phase modulate the carrier with the signal and apply the phase modulated carrier to the fence line. Each receiver device includes means arranged to demodulate the transmitted signal to recover the data block(s) and process the data block(s) to recover the control signals(s) or information. The system is adapted to work with both electric and non-electric fence lines.

  • Method of estimating timber stiffness profiles
    Patent number: 6889551
    Abstract: The invention relates to methods and apparatus for estimating stiffness or elasticity profiles across timber. This involves measuring a velocity of a plane compression wave propagating in the timber, determining density information relating to the timber and estimating an initial elasticity profile.

  • Electrochemical process for effecting redox-enhanced oil recovery
    Patent number: 6877556
    Abstract: A method is provided for recovering oil from a subterranean oil-bearing formation. One or more pairs of electrodes are inserted into the ground in proximity to a body of oil in said formation. A voltage difference is then established between the electrodes to create an electric field in the oil-bearing formation. As voltage is applied, the current is manipulated to induce oxidation and reduction reactions in components of the oil. The oxidation and reduction reactions lower the viscosity in the oil and thereby reduce capillary resistance to oil flow so that the oil can be removed at an extraction well.

  • Method for making reduced calorie cultured cheese products
    Patent number: 6861081
    Abstract: A method is disclosed for making reduced calorie cultured cheeses whereby the natural lipid content of milk is replaced with colloidal forms of synthetic or chemically structured lipids displaying low to no human digestibility. The colloidal dispersion of modified lipids contained within the milk base is initially stabilized by preferred combinations of polymeric and particulate hydrocolloidal materials such as structurally expanded cellulose. Such stabilization is important during formation of the curd to ensure homogeneous distribution and maintenance of the lipid dispersion throughout the coagulum yet allow effective concentration of the coagulum solids by means of ordinary water removal methods commonly used in the manufacture of conventional cultured cheeses. The coagulum is then processed by means similar to that employed for naturally fermented cheeses.
