Inventor: HUNDEBOL SOREN
IPC: C04B7/43
Filed: 1997-01-22
Abstract: The invention relates to a method for reducing the NOx emission from a kiln plant for heat treatment of raw materials, in which kiln plant fuel can be fired in at least three different zones. In one of these at least three zones an amount c of fuel is burned, in a second of these zones an amount b of fuel is burned and to this second zone the NO containing exhaust gases from the other at least two zones are also fed. In the rest of these at least three zones an amount a of fuel is burned and at least a part of the raw materials are fed to these zones together with an oxygen containing gas. The total amount of fuel, b + a, burned in the second and in the last zones is determined by the need for treatment of the raw materials. When the kiln plant is used for manufacturing cement clinker, the heat treatment consists of preheating, calcining, sintering and cooling of the mineral raw materials. The invention seeks to provide a method by means of which a reduced NOx emission from a kiln plant is obtained, allowing, at the same time,utilization of fuels of low reactivity, such as petroleum coke, anthracite and other coals with a low gas content, in zones at a relatively low temperature. In accordance with the invention, this objective is accomplished in that the amounts of fuel, b and a, are adjusted in upward and downward direction until a minimum NO content is achieved in the exhaust gases from the zone to which the NO containing exhaust gases from all other firing zones are fed.

Title: System and method of co-ordinating communications for telecommuters
Inventor: SHAFFER SHMUEL
IPC: H04M3/523
Filed: 1997-03-19
Abstract: A system and method of providing site-to-site compatibility of telecommunications stations allow users to transparently relocate among a number of different stations, while the apparent locations of the users remain fixed. Co-ordinator modules of a private branch exchange (PBX) establish peerto-peer communications with station-based co-ordinator modules to provide automated routing to the station at which the particular individual is located, while leaving the apparent location of the user fixed at a designated station of the PBX. In one embodiment, the compatibility of stations allows the user to operate from a home-based station, while the apparent location of the user to any calling and called parties is an office-based station that is dedicated to the user. In a second embodiment, the compatibility allows the user to operate from any one of a variety of office stations, while the apparent location remains fixed at one of the office stations. These stations preferably include computers or other equipment that support multimedia transmissions. The user logs on at one of the telecommunications stations in order to designate the station as the "primary station" for purposes of routing incoming calls. The co-ordinator module that is dedicated to a particular user acts as a virtual office that has no geographical location with respect to conventional office equipment. In the preferred embodiment, coordinator modules may be located on line cards of the PBX.

Title: Waste treatment of metal plating solutions
Inventor: ALEXANDER CELIA L
IPC: C02F9/00
Filed: 1998-10-26
Abstract: An efficient and economical process for the waste treatment of spent metal plating solutions, primarily spent electroless nickel solutions, to significantly reduce the metal content therein, so as to permit direct discharge to municipal water systems without violation of the law. The waste treatment process is a sequential two-step chemical precipitation process, whereby the dissolved metal content is precipitated first by sodium borohydride reduction, followed by sodium dimethyldithiocarbamate precipitation, with an intermediate filtration step and pH adjustment step interposed there between. The amount of metal-bearing sludge produced is minimal. Furthermore, the bulk of the metals in the sludge may be recovered and reused, resulting in significant reduction in hazardous waste disposal costs.

Title: Method and apparatus for measurement directed hard handoff in a cdma system
Inventor: BAKER KENNETH R
IPC: H04W36/14
Filed: 1997-05-22
Abstract: In a communications network, a network user communicates using a remote unit (125) with another user (30) via at least one base station (B1A). The network is comprised of first (MSC-I) and second (MSC-II) mobile switching control stations respectively controlling communications through a first set of base stations (B1A-B1E) including a first base station (B1A) and through a second set of base stations (B2A-B2E) including a second base station (B2A). To direct communications between the remote unit (125) and the first (B1A) and second base stations (B2A) the first base station (B1A) measures a round trip delay of an active communication signal between the first base station (B1A) and the remote unit (125). The remote unit (125) measures a first phase offset of a pilot signal received from a first candidate base station (B1A) and reports it to the first mobile switching center (MSC-I) via the first base station (B1A). The first mobile switching center (MSC-I) calculates a candidate round trip delay between the remote unit (125) and the first candidate base station (B1A) based on the first phase offset and the round trip delay of the active communication signal. An active communication control unit accesses a measurement directed hard handoff table to determine a location of the remote unit based on the round trip delay corresponding to the first active communication signal and the candidate round trip delay.

Title: Scalable high performance switch element for a shared memory packet or atm cell switch fabric
Inventor: VENKATARAMAN KRISHNAN
IPC: H04L12/56
Filed: 1997-03-05
Abstract: A scalable high performance ATM cell/packet switch (HiPAS) element for a shared memory switch fabric application. The switch clement includes a PAC Bus (Packet/ATM Cell Bus) and the Switch Fabric Controller Bus (SC Bus). The HiPAS switch element receives and transmits the ATM cells/packets through the PAC      Bus. The PAC Bus provides independent parallel datapaths for the receive port and transmit port. The PAC Bus provides a unique structural feature to the HiPAS switch element and allows expansion to the switch capacity in a manner similar to a bit-slice processor. Multiple number of HiPAS switch elements can be concatenated to expand the capacity. In the concatenated configuration, the datapaths of the receive port and transmit port are interleaved so that the interconnection remains point-to-point. As the result, all of the switch ports in the switch execute the cell transactions concurrently on the PAC Bus. In addition, each switch fabric port has a dedicated serial port to exchange status information between the switch fabric and the switch port adapter.

IPC: E05B11/06
Filed: 1997-07-18
Abstract: A cylinder lock (10) comprises a shell (14), a core (12), and a plurality of pin tumbler stacks (22, 24). The core includes an outer surface, a keyway and a cut-out offset from, but alignable with, at least one of the tumbler stacks. A plate (34) disposed on the cut-out is movable between a first position, wherein the plate acts as an extension of the core surface to prevent a tumbler stack from entering the cut-out, and a second position, wherein the plate does not prevent a tumbler stack from entering the cut-out. Upon insertion of an authorized key (46) having a projection (58) extending from a side thereof, the projection urges the plate from the second position to the first position to permit the core to rotate to an unlocked position. Upon the insertion of a properly bitted key, but without the projection, only partial rotation is permitted whereupon the tumbler stack enters the cut-out to thereby render the lock inoperable and trap the unauthorized key within the keyway.
