Patent CA-2181457-A1 (CA)
Title: Terrain elevation path manager
Inventor: GJULLIN ROBERT M
IPC: G01C7/02
Filed: 1995-01-17
Abstract: A terrain profile for executing terrain following flight is generated using a minimal volume of digital terrain elevation data (DTED) information. By limiting the amount of information considered in generating the terrain profile, the computational time and resource requirements for terrain profile generation are reduced, but without comprising the integrity of the terrain profile generated. The sample region is limited by limiting the width of sample regions according to expected use including most likely terrain following flight command data, potential unexpected flight path deviation, and long range terrain following flight data.

Title: Secondary disconnect assembly for high ampere-circuit breaker
Inventor: DRUMBOR REBECCA CHRISTINE
IPC: H01H9/02
Filed: 1996-01-26
Abstract: A secondary disconnect arrangement, in the form of a plug connector (51) attached to the sides of a high ampere-rated circuit breaker assembly (10), interacts with a receptacle connector (28) attached to the inner side walls (34, 35) of a circuit breaker enclosure (33). Movement of the circuit breaker (10) into and out of the enclosure (33) automatically connects and disconnects the plug connector (51) from the receptacle connector (28). Terminals (30) arranged on the plug connector (28) on one side of the circuit breaker (10) connect with the internal circuit breaker components for communication and control functions via components (29, 31), while terminals (41-44) arranged on the plug connector (28) on the opposite side provide connection via terminal array (70-73) between the internal circuit breaker components and remote auxiliary devices.
Patent CA-2185289-A1 (CA)
Inventor: TAN HAN HIONG
IPC: H04B10/291
Filed: 1996-09-11
Abstract: Optical network for signal transfer from a central station to subscriber stations. The signal to be distributed is split in at least two stages, with thesignal being amplified by optical amplifiers. The Erbium Doped Fiber Amplifiers (EDFAs) to be used for this purpose are fed by an optical supply signal. By building up the supply signal from various signals with wavelengths lying closely together, Stimulated Brillouin Scattering (SBS) is avoided. As a result, by utilising centrally supplied EDPAs more splitting stages may be applied, as a result of which many more subscribers may be reached from one signal source than before. The subscribers may utilise inexpensive, low-sensitivity receivers. The optical network is particularly suited to form, in conjunction with a conventional non-optical (twisted-pair) network, a hybrid bi-directional transmission system. In this connection, the optical network is intended for the distribution of wide-band signals (CATV) and the non-optical network for bi-directional transfer of narrow-band signals.

Inventor: ROSSITER V PAUL
IPC: E04B2/82
Filed: 1996-10-25
Abstract: A light weight, upholstered panel for use in modular and free standing office landscaping systems. The panels form free standing partitions which can be rearranged and assembled into an office system. Panels can be interconnected and positioned over a range of angles relative to adjacent panels. The panel core is composed of a light weight composite structural material with perimeter frame members along each edge. Each frame member has the same cross-section along its length. The horizontal perimeter horizontal frame members are inter-connected with the vertical frame members by corner connectors. The corner connectors have protrusions which engage hollow cavities in the ends of the frame members. The perimeter frame acts to transfer loads imposed on the panel to the structural core. The perimeter frame members incorporate formations to secure the panel fabric, trim and the inter-panel connection system in place and provide recesses for fasteners and support hardware.

Title: Method and arrangement for establishing call connections in a telecommunications network using a virtual transport server
Inventor: BORCHERING JAMES WILLIAM
IPC: H04M7/06
Filed: 1996-12-17
Abstract: A telecommunications network comprises a virtual transport server (VTS) for making network routing decisions and establishing call connections. Each VTS is interconnected to each signal transfer point in a common channel signaling (CCS)system associated with the network. Each VTS is also interconnected to at least one switch in a transmission network, such as an asynchronous transfer mode (ATM) switch. The VTS maintains routing tables identifying trunk groups associated with each central office switch in the network. During operation, an initial address message received from a signal transfer point in the VTS is processed and subsequently extended to an ATM switch so that a call connection can be established. Upon completion of the established call, the VTS releases resources associated with the ATM switch.

Abstract: In a process for the production of molten pig iron or molten steel pre-products and sponge iron from charging materials consisting of iron ore and, if desired, fluxes, direct reduction of the charging materials to sponge iron is carried out in a fixed-bed reduction zone (12), the sponge iron is melted in a meltdown gasifying zone (8) under supply of carbon carriers as well as an oxygen-containing gas and a CO- and H2-containing reducing gas is produced which is fed to the reduction zone (12), is reacted there and is drawn off as an export gas, and the drawn-off export gas is subjected to CO2 elimination and for the production of sponge iron is along with part of the reducing gas formed in the meltdown gasifying zone (8) as an at least largely CO2 free reducing gas conveyed to a further reduction zone (21) for the direct reduction of iron ore. In order to save investment costs incurring with regard to a plant for carrying out the process and to increase productivity, part of the reducing gas produced in the meltdown gasifying zone (8) is branched off and fed to the further reduction zone (21) while avoiding CO2 elimination (Fig. 1).

Title: Method of cooling multilayer preforms
Inventor: KRISHNAKUMAR SUPPAYAN M
IPC: B29B13/04
Filed: 1995-12-27
Abstract: Method of making multilayer preforms which resist delamination and in a reduced cycle time. A first array of preforms are molded onto a first array of cores in an associated array of mold cavities, the cores and preforms are removed from the mold cavities as soon as possible without significant physical preform deformation, and the preforms are then cooled on the cores while a second array of cores is positioned in the mold cavities.      Cooling on the cores prevents delamination of the preform layers and reduces the in-mold cooling time. Providing multiple sets of cores on a rotating turret further reduces the cycle time compared to the prior art use of robotic cooling tubes.
