20110206204 | METHODS AND DEVICES OF QUANTUM ENCODING ON DWDM (ROADM) NETWORK AND FIBER OPTIC LINKS . - The invention solves the following complicated problems. Elaboration of the procedure for secret key extraction from the lower layer optic signal even in a presence of noise in fiber-optic cable. The realization of the quantum protection amplification scheme to clean states of the entangling polarized photons against noise in optical channels, especially in case of use Einstein-Podolsky-Rozen method with single photon source for transmitting and measuring secret keys photon polarization in ROADM network. The development of a system for code key transmission that satisfies requirements of fortuitousness and privacy along with speed enlargement of the key generation in ROADM network. The achievement of the acceptable optical fiber amplification without losing its behavior and the protocol determination, which will allow to detect and correct bit errors in fiber optic cable and ROADM network, caused by linear and nonlinear effects. The development of quantum encoding systems for telecommunication topologies. | 08-25-2011 |

20120205101 | METHOD FOR MAKING RESIN-COATED PROPPANTS AND A PROPPANT - A method for making resin-coated proppants comprising applying epoxy and phenol resins with a curing agent onto the surface of proppants. The epoxy and phenol resins with the curing agent are applied onto the surface of the mix of proppants. The mix of proppants is obtained by blending heavy proppants with bulk density of 1.4 g/cm3 and more, with lightweight proppants with bulk density of less than 1.4 g/cm3. The application of the epoxy and phenol resins is performed at temperatures from 5 to 35. degrees Celsius. | 08-16-2012 |
