  • Patent number: 6770635
    Abstract: Adverse inflammatory reactions can be treated by administrating to an organism a composition having diglucosylamine as the active ingredient. The preferred compound is di-Beta-D-glucopyranosylamine. A simple method for making diglucosylamine in high purity is obtained by reacting glucose, a nitrogen containing base, and either methanol or ethanol to form the diglucosylamine and then recovering the diglucosylamine preferably with the use of charcoal. The preferred diglucosylamine, di-Beta-D-glucopyranosylamine, has extraordinary anti-inflammatory activity. It can be formulated with a pharmaceutically acceptable carrier to make pharmaceutical compositions which are effective in treating inflammations. This pharmaceutical composition can also be used to treat adverse inflammatory reactions that are the result of the disruptions of a dynamic network of cellular mechanisms in organisms.

  • Patent number: 6311006
    Abstract: ADSS cable is laid out a length of cable along an aerial route defined by a series of poles, and loops of surplus cable are formed at occasional poles. The cable is raised to a predetermined installation height at each pole, where two dead-ends secure the ends of the loop so that the loop is substantially free of tension. The center of the loop is raised and secured to the pole, thus forming two bights in the loop. A bend radius protector is installed in each of the bights to protect the cable from bending damage. Each bend radius protector is suspended from a cable protecting device placed over the taut cable, so that the cable is not damaged.

  • Patent number: 6289141
    Abstract: This invention provides a system that utilizes the magnetic properties of specific materials to provide an authentication and/or authorization function. The system consists of two parts. The first is a marker that contains a magnetic material with spectral magnetic properties and is attached to the item that is to be authenticated or is to be part of a subsequent information transfer process requiring authorization. The second is a reader. The reader contains a transmitter that generates the electromagnetic search field and energizes the magnetic material and a receiver that analyzes the signal produced by the resulting interaction with the magnetic material and gives a go/no go decision based upon a match with stored information. The reader employs a feedback control system to stabilize the measurement environment, thereby producing accurate, high quality results.
