Abstract: A package of a strip of material is formed by slitting or perforating a web to separate the web into side by side strips and fan folding the web to form a plurality of side by side stacks of the strips. The strip material is formed of fibrous non-woven material containing a proportion of thermally bondable material. An end of the first strip portion is connected to an end of the second strip portion to form a continuous length of the strip material to be supplied to an end use machine in which the strip material is used to manufacture a composite product including the strip material. The splice is formed by ultrasonically heat sealing the strip material ends.

Title: Method and apparatus for steam reforming of chain hydrocarbon
Inventor: SEKINE YASUSHI
IPC: B01J19/08
Filed: 2001-03-19
Granted: 2010-02-09
Abstract: Disclosed is a novel method for steam reforming, by which selectivity to carbon monoxide is high, which is free from various side reactions, which may be carried out at a lower temperature and at a lower pressure than the conventional methods, and which may be carried out even if a catalyst is not used. In the method of the present invention, direct current pulse discharge is performed in a mixed gas containing a gaseous chain hydrocarbon and water vapor so as to react the chain hydrocarbon and the water vapor, thereby generating hydrogen and carbon monoxide.

Title: Usage-based billing for voice over packet communications
Inventor: JONES BRYCE A
IPC: H04L12/66
Filed: 2002-05-22
Granted: 2008-04-29
Abstract: A communication system (100) is disclosed that provides usage-based billing for voice communications transmitted over a packet system (106). The communication system is comprised of a packet billing system (104) that sniffs signaling transmitted between a signaling processor (102) and a communication device (112), such as a switch or a router. If the packet billing system detects a call setup message in the signaling, then the packet billing system generates a start record. If the packet billing system detects a call complete message in the signaling, then the packet billing system generates an end record. The packet billing system transfers the start record and the end record to a conventional public switched telephone network (PSTN) billing system (194). The PSTN billing system generates a bill for the call based on the start record and the end record. The communication system advantageously provides usage-based billing for packet-based calls using the conventional PSTN billing system.

Title: Design improvements to vacuum glazing
Inventor: TANG JIAN-ZHENG
IPC: E06B3/66
Filed: 1995-09-28
Granted: 2008-07-29
Abstract: Vacuum glazings and methods of manufacture thereof are described; the glazings provide improved shear stress resistance in that the vacuum glazing comprises two sheets of glass (2, 3), hermetically sealed around the edge (4), with a thermally insulating internal vacuum, and an array of support pillars (5) placed between the glass sheets (2, 3), wherein the pillars (5) consist of a core (13), made of a material of higher compressive strength, with at least one end covered by a layer of softer material (14). Alternatively, the vacuum glazing comprises two sheets of glass (2, 3), hermetically sealed around the edge (4), with a thermally insulating vacuum, and an array of support pillars (5) placed between the glass sheets (2, 3), wherein the array includes a small number of fused solder glass pillars located over the surface of the glazing, between pillars of higher compressive strength. Advantageously the support pillars (5) comprise two flat parallel ends (15, 16) shaped to provide stable equilibrium, and sides (17) shaped to provide unstable equilibrium, to ensure that the pillars when placed on a glass sheet will fall onto one of the flat faces (15, 16) and thereafter lie on that face.

Title: Sawing direction positioning system for a jigsaw
Inventor: ZHANG ROSS
IPC: B23Q17/24
Filed: 2004-06-10
Granted: 2007-08-07
Abstract: The present invention relates to a sawing direction positioning system far a jigsaw comprising a light-emitting unit for emitting a planar light beam, said light-emitting unit being connected with a power supply via a lead and positioned above said jigsaw so that said planar light beam emitted from the Light-emitting unit coincides exactly with the plane of a saw blade mounted on said jigsaw. During sawing, the projection line of the planar light beam always projects on the wood to be sawed and is not obstructed by the sawdust. The operator may have a good visual field and push the wood to be sawed along the curve line to ensure that the projection line always keeps tangential to the curve fine drawn on the wood and the saw blade always saws the wood along the projection line, thereby preventing the kerf from offsetting and reducing the rejected products.

Abstract: A system and method for evaluating at least one communication link between a transmitting node and a receiving node in a communications network, such as a wireless ad-hoc communications network in accordance with the 802.11 standard. The system and method perform the operation of assigning respective link quality values to the respective communication links based on a transmit power level (TPL) value at which the respective data packets were transmitted by the transmitting node over the respective links, a received sensitivity (RS) value of the receiving node receiving the data packets, and a receive signal strength indication (RSSI) value provided by the network for each respective link. The system and method can examine a content of a data packet being sent between the two nodes to determine the TPL, and can receive the RSSI value from a physical layer of the communications network. Accordingly, the system and method can determine which link that additional data packets are to be sent by the transmitting node to the receiving node via the communication link based on the link quality values. Specifically, the link having the highest link quality value is selected.
