Title: Method and system for communication over multiple channels in a spread spectrum communication system
Inventor: SEXTON THOMAS A
IPC: H04W72/04
Filed: 1996-11-26
Abstract: A method for transmitting a communication signal (20) having a data rate over a plurality of spread spectrum traffic channels includes determining a first number of traffic channels required to transmit the communic ation signal at the data rate, and determining a second number of traffic channels (502) available for transmitting the communication si gnal (20). In response to a comparison of the first number of traffic to the second number of traffic channels, a first traffic channel (54 ) for transmitting a first portion of the communication signal (50, 51) and a second traffic channel (56) for transmitting a second portion of the communication signal (52, 53) are selected from the second number of traffic channels (502). The selection of the first traffic chan nel (54) is non deterministic of the selection of the second traffic channel (56).

Title: Treatment of waste products that contain organic substances
Inventor: LEHNER THEO
IPC: C22B5/16
Filed: 1996-10-11
Abstract: The invention relates to a method for treatment of waste products that contain organic materials, such as plastic and like organic materials, and frequently also containing metal values, including precious metals, by thermal processing, without risk of generating dioxins or similar toxic compounds and in a manner which also enables any metal values to be recovered. The method is characterized by charging the waste products to an agitated smelt in a manner which will prevent the products being heated to any significant degree prior to being surrounded by the agitated smelt. The waste products are mixed vigorously in the smelt in the presence of reducible constituents or components at a temperature of at least about 1250 °C, wherein plastic and other organic material is decomposed thermally to reduction agents for the reduction of said reducible constituents or components, and therewith converted essentially fully to complete combustion products, such as CO2 and H2. Any metal values present are taken out as metal-rich dustand/or metal-rich molten phase, and the metal values can be recovered from the metal-rich products in a suitable known manner. The invention also relates to a method of destroying, or rendering harmless, waste products that contain organic substances, such as plastic or like organic compounds, without the risk of forming dioxins or like toxic compounds.

Inventor: NOLDE KEITH ERIC
IPC: H04M9/02
Filed: 1996-10-16
Abstract: A switching system for inclusion in domestic premises (2) includes a master socket (11) for connection to network termination equipment (e.g. wall socket) (6) and for connection to a plurality of slave sockets (12) each of which may be connected to normal communications apparatus such as telephone (7), fax or answering machines not shown. On receipt of an incoming telephone call from the network the master socket uses signals which identify the source of the call (calling line identity (CLI)) signals to determine which of the slaves is to be called. Using only four wires (i.e. the normal extension wiring pattern) the master socket can signal individual slave sockets (12) to switch in or out of circuit so that a normal domestic telephony arrangement may be simply and economically converted to include switching. Various protective options and alternative calling patterns in event of non-answer can also be provided by the master socket including options for allowing communication between two individual extensions without utilising the main exchange line system.

Title: Space launch vehicles configured as gliders and towed to launch altitude by conventional aircraft
Inventor: KELLY MICHAEL S
IPC: B64D5/00
Filed: 1995-11-13
Abstract: Orbital launch vehicles (1) with aerodynamic lifting surfaces (2) enabling them to be towed as gliders behind conventional aircraft (19), and the method of towing these launch vehicles using a flexible cable (18) to connect them with a conventional aircraft (19), for placing spacercraft (15) into low earth orbit at greatly reduced cost compared to current orbital launch systems. The lift from the aerodynamic surfaces (2) enables the launch vehicles (1) to be towed by means of a flexible cable (18) from a conventional runway using existing aircraft (19). As with "conventional air-lauch", this permits spacercraft launch into orbit to originate from any conventional runway consistent with constraints of public safety, thus eliminating the need to build dedicated launch pads at geographic locations from which a full range of orbital inclinations can be reached.

Title: Data comparison agc system for vsb receiver
Inventor: KIRSHNAMURTHY GOPALAN
IPC: H04L27/06
Filed: 1997-10-03
Abstract: A technique and apparatus for developing AGC voltage in a receiver (fig. 1) capable of receiving VSB signals (RF IN) that do not have the data symbol levels and the sync symbol levels related so as to produce the same average magnitude level. Successive portions of the signal are accumulated, stored (38-44) and compared (46) with the smaller of the samples to be used to develop the AGC voltage. By comparing the first and third of three successive samples, the effect of the larger than desired sync levels in the over-the-air VSB signals is completely eliminated.

Title: Remote procedure calls in distributed systems
Inventor: HAMA MELVIN SEIJI
IPC: G06F9/46
Filed: 1998-06-29
Abstract: A multi-threaded, multi process distributed system including remote call procedure (RPC) messages. The threads in the distributed system are each associated with a queue. The RPC messages each include an indentifier to identify the queue which is associated with the thread which has originated the RPC message, as well as an identifier indicating the connection over which the RPC message is communicated from one process to another. The connection over which RPC  requests are forwarded in the distributed system is made between one process and another process. The RPC messages sent between processes utilise the same connection, independent of which thread in each process is sending or receiving the messages. RPC messages are forwarded through the distributed system and the connection and queue identifiers in the RPC messages are updated as the message is forwarded from process to process in the distributed system.
