Title: Adaptive receive and omnidirectional transmit antenna array
Inventor: PROCTOR JAMES A JR
IPC: H04M1/00
Filed: 2003-03-10
Abstract: An adaptive antenna (120) used in a receive only mode with a separate transmit antenna such as in a handheld wireless device (100). The transmit antenna may be integrated with the receive array by utilizing a horizontally polarized transmit and vertically polarized receiver array. In other embodiments, the transmit antenna may be physically separate and not integrated with the receiver array. In either case there is separate receive and transmit signal port as an interface to radio transceiver equipment. The use of an adaptive antenna on the receiver only direction has potential to increase the forward capacity to levels equal to or greater than reverse link capacity. This allow for a significant increase in the overall number of voice users that may be active at the same time in a conventional wireless system without directly effecting the reverse capacity.

Title: Method and production line for producing high-silica inorganic fibers from rocks and continuous and staple fibers and scaly particles produced by said method
Inventor: KIBOL VIKTOR FEDOROVICH
IPC: C03B5/04
Filed: 2003-04-21
Abstract: The inventions relate to means for producing high silicate inorganic fibres from natural acidic rocks and to articles made from said fibres, i.e.  continuous and staple fibres and scaly particles. In each variant C., dacite or riodacide or granite or riolite or sandy rock whose content in silicium oxide is equal to or higher than 73 % is used as a rock. The aim of the inventions is to develop means for producing inorganic fibres from natural acidic rocks and articles made from said fibres, i.e. continuous, staple and coarse fibres and finely dispersed scaly particles exhibiting high strength, and corrosion and thermal resistance. The aim is achieved by removing foreign inclusions, which have high fusion and boiling temperatures, from the melt by using rocks with high silicon oxide (SiO 2) content and, therefore a high fusion temperature, thereby evacuating the major part of foreign inclusions from a melt into the atmosphere.
