Abstract: A pin (20) is provided for securing a replacement ligament (24) inside a tunnel (10) of a receptor bone (36). A threaded section (30) of the pin (20) engages and anchors the pin (20) in the receptor bone (36). A first taper (26) opposite the threaded section (30) is configured to enter a drilled hole (14) which is transverse to the tunnel (10), capture a looped replacement ligament (24), and extend into the medial side (25) of the receptor bone (36). A second taper (28) urges the replacement ligament (24) against the wall (15) of the tunnel (10) and provides resistance when the second taper (28) contacts the medial side (25) of the bone (36), thus signaling that the pin (20) has been inserted to the proper depth. The body (21) of the pin (20) secures the looped replacement ligament (24) in the tunnel (10) and holds the replacement ligament (24) in contact with the wall (15) of the tunnel (10) to insure ingrowth.

Abstract: A network arrangement for delivering IP services to subscribers includes a core network, a plurality of label switched media gateways coupled to the network and each providing an interface for one or more subscriber terminals. Call servers associated with the network are used to establish connections between pairs of gateways, these connections being routed across the core network via tunnels established therein. The tunnels are exclusively reserved for traffic between the label switched media gateways so as to provide security of that traffic from third party access and to provide a guaranteed quality of service. Because traffic is accepted into a tunnel only if bandwidth is available in that tunnel, firm and meaningful quality of service guarantees can be given to users.

Abstract: A glass composition for a seal consists essentially of 70-75 wt % of PbO, 3-7 wt % of PbF2, 5-8 wt % of Bi2O3, 5-7 wt % of B203, 2-5 wt % of ZnO, 1-3 wt % of Fe2O3, 0-2 wt % of CuO, 0-2% of TeO2, and a trace <0.2% of MnO2, the composition having a flow temperature of <350° C. Such seals can be flowed at low temperatures, using different and less environmentally damaging constituents to those used before. Damage to temperature sensitive materials near the seals, can be reduced. Low flow temperatures can be achieved without excessive degradation of properties such as low viscosity, low expansion coefficient, good adhesion to glass and metals, low permeability of air, good long term hydrolytic stability. A filler such as a ceramic powder, is added to match the temperature expansion coefficient to the materials being sealed. It can be used to fix silica fiber into electro-optic devices to achieve hermetic joints with high mechanical stability.

Abstract: The present invention relates to data tunnelling and in one embodiment to the tunnelling of IP (Internet Protocol) data across an OSI (Open Systems Interconnect) network. In the preferred embodiment, network elements include both an OSI stack and an IP stack, and a respective directory of OSI addresses and corresponding IP subnets. Each network element generates a routing data packet, conveniently a Link State Packet (LSP), which includes the OSI address and IP subnet(s) associated with that network element. The LSPs are distributed across the network in normal manner. Upon receipt of an LSP from another network element, each network element updates its respective directory in respect of said other network element. Thus, each directory is automatically updated to reflect changes in the network, particularly in respect of IP subnets. This arrangement significantly reduces the need for manual tunnel configuration in the network.

Abstract: In a cellular mobile telecommunications system the position of a mobile station can be estimated in terms of its bearing and range from a cell site. A multi-element direction finding antenna at the cell site receives signals from the mobile station and a receiver circuit estimates the bearing using the relative phase of signals received at different antenna elements and estimates the range by measuring round trip delay of signals to and from the mobile station. Motion of the mobile station can introduce errors into the bearing estimate due to frequency offset and frequency spread when element sampling is non-simultaneous. Compensation for these errors is introduced by using signal samples successively received at the same antenna element to estimate Doppler frequency offset and spread. It is necessary to ensure accurate calibration of the direction finding antenna and the receiver circuit.

Abstract: A musical instrument and a method of operating it. An instrument and method which retunes and adjusts volumes in response to the chord being sustained and the way that chord is voiced. The instrument is capable of producing tones, the intervals between which are equal tempered intervals of a twelve note octave, and tones, the intervals between at least some of which are determined by identifying at least selected ones of the notes the instrument is being commanded to produce. The method includes identifying the at least selected ones of the notes the instrument is being commanded to produce, providing a map for mapping the identified notes to a chord type, identifying a note in that chord type, and substituting a frequency closer to a harmonic of the identified note for the frequency of at least one harmonic of at least one other note the instrument is being commanded to produce.

Abstract: A twin roll caster (11) produces thin steel strip (12) which passes through a first enclosure (37) to a pinch roll stand (14) including pinch rolls (50) through which the strip passes into a second enclosure (61). The strip passes horizontally through enclosure (61) to an in-line hot rolling mill (16) which closes the exit end of enclosure (61) and hot rolls the strip as it exits that enclosure. Enclosures (37) and (61) are sealed against ingress of atmospheric air and both maintain oxygen levels less than the surrounding atmosphere to reduce formation of scale on the strip. The second chamber (61) is fitted with water spray nozzles (67, 68) operable to spray fine mist of water droplets onto the upper face of the strip as it passes through that enclosure thereby to generate steam producing a superatmospheric pressure within the enclosure preventing ingress of atmospheric air.
