Title: A conveyor cable and a method for manufacturing such a conveyor cable
Inventor: ECHBERG INGOLF
IPC: B65G19/14
Filed: 1997-10-03
Abstract: A conveyor wire (2) is described which is intended to be used in a scraping conveyor (1).      The scraping conveyor is primarily usable for bringing fodder from a silo (5) via a conveyor duct (4) to feeding stations (6). The conveyor wire (2) is provided with scraping elements (3) which are equidistantly distributed along the length of the wire in order to convey the material through the conveyor duct (4). The wire (2) is manufactured from synthetic fibre strands on which scraping elements (3) are moulded or welded. The scraping elements (3) are manufactured from a material having a melting temperature which is lower than the temperature at which the synthetic fibres of the wire (2) carbonise. Hereby a very safe moulding is achieved so that the scraping elements are positioned firmly on the wire and cannot be displaced in the longitudinal direction. As the synthetic fibres are non-extendible, the scraping elements will not be wrongly positioned in relation to driving wheels and turning wheels (8, 9).      Hereby a safe operation is obtained.

Title: Method and apparatus for implementing in video a secondary game responsive to player interaction with a primary game
Inventor: ACRES JOHN F
IPC: G06F19/00
Filed: 1999-04-27
Abstract: A method for operating a group of gaming machines interconnected by a network to play both primary and secondary games from the machines. Each of the gaming machines has a primary game associated with it. Play is allowed to occur on the gaming machines while a triggering event is detected. In a preferred embodiment, the triggering event is detected by monitoring an operating parameter of the gaming machines over the network, such as total coins played. A predetermined criterion or threshold is set for the operating parameter and, if the operating parameter meets the predetermined criterion, a triggering event signal is sent through the network. Upon the occurrence of the triggering event, a secondary game is initiated from a selected one of the gaming machines whereby the secondary game is common to the group of gaming machines. The secondary game is most preferably a wheel-of fortune-type game and is displayed in common to all of the machines and local spectators on a plasma-based display monitor of the type marketed by Fujitsu under their Plasmatron TM brand.  Driving the plasma-based monitor is an animation computer that contains software coded animation programs for displaying the wheel-of fortune and related audio/video events responsive to a stand-alone bonus server (SBS).

Title: Backup procedure for signalling links
Inventor: NAIDOO NILANTHREN V
IPC: H04Q11/04
Filed: 1999-07-23
Abstract: A method of improving the signalling performance reliability of an interface between a signalling agent and a network element such as an ATM switch in a DSS2 asynchronous transfer mode network.       In the case of a non-redundant signalling agent, a primary link is established between a first Layer 2 port of the signalling agent and a first Layer 2 port of the network element; and, a primary backup link is established between a second Layer 2 port of the signalling agent and a second Layer 2 port of the network element. The Layer 2 ports are coupled to Layer 3 segments of the signalling agent and the network element respectively, in accordance with established ATM protocols. During normal operation of the primary link, the primary link is maintained in an active state in which all signalling messages directed to the interface are transferred between the Layer 3 segments over the primary link. The primary backup link is maintained in a standby state in which the primary backup link is active between the second set of Layer 2 ports, but inactive between the Layer 3 segments. Upon abnormal operation of the primary link, the primary link is switched into an inactive state to prevent further transfer over the primary link of signalling messages directed to the interface; and, the primary backup link is switched into an active state in which all signalling messages directed to the interface are transferred between the Layer 3 segments over the primary backup link.

Title: Valve cartridge for lift valve having the closing pressure on the sealing limited
Inventor: FRIDLENDER CHARLES
IPC: F16K31/50
Filed: 1998-01-07
Abstract: Valve cartridge (10) includes a housing (32) having inlet member (54), outlet member (52) and screw thread (34). Cavity (36) extends axially through housing (32) within which is a piston (38) which moves axially against piston seal (44) to open and close tap (10). A flow chamber (40) is provided at the end of housing (32) and includes a first seal (42) for sealing against a valve seat (18) in the tap (10). Piston (38) can be moved axially by either a rotatable spindle (46) or, a solenoid (48) and push rod (50). Piston (38) is moved axially without any rotation. Coupling member (84) couples spindle (46) to piston (38) and rotates relative to the piston (38) and the spindle. When spindle (46) is turned a predetermined number of revolutions the coupling (84) causes piston (38) to abut piston seal (44), any further rotation of spindle (46) causes rotation of the coupling member (84) without effecting the axial position of piston (38). Ratchet members (92, 94), slip past housing splines (102) when the predetermined number of revolution or force is reached. This limits the sealing pressure of the piston (38) against the piston seal (44) irrespective of the number of turns made of spindle (46). Stops (64) limits maximum opening and prevents check valve (70) from being forced into sealing contact with inlet member (54).

Title: Wireless access to packet-based networks
Inventor: VARADHAN KANNAN
IPC: H04L12/56
Filed: 1999-10-29
Abstract: Domains are defined to incorporate a subnet including a plurality of base stations and routers. Base stations are used by mobile devices to attach to the wired portion of a packet-based network, such as the Internet, and exchange packets thereover with a correspondent node. Local mobility between domain base stations is provided by including and updating routing table entries at domain routers and base stations for forwarding packets having a mobile device's address as a destination address to the mobile device. Packets are delivered to the mobile device regardless of the domain base station to which the mobile device is attached. When a mobile device is attached to a base station included within a foreign domain, a care~of address is assigned, and packets are tunneled for delivery of packets to the mobile device. Only one care-of address is required per mobile device per foreign domain. Routing table entries used for packet delivery are updated on a purely local subnet basis within domains, whether home domain or foreign domain, making handoffs between base stations substantially transparent to the home agent and the correspondent node.
