Title: Transmitter-based path protection switching in a ring network
Inventor: DUPONT JEAN-LOU
IPC: H04L12/437
Filed: 2000-05-23
Abstract: A system and method for path protection switching in ring networks is provided in which the path protection switch occurs at the transmitter node that initiated a particular virtual channel of data packets onto the ring network. A failure in one of the data communication-paths of the ring network is detected by the network nodes on either side of the failure. These network nodes then initiate a wrap mechanism that embeds a special feedback wrap indicator flag into packets received at the two nodes, and then wraps (or transmits back) these packets (with the feedback indicator) in the opposite direction towards the transmitter node that initiated the packets onto the ring. Each transmitter node detects whether received packets are associated with virtual channels that it initiated onto the ring and if so detected, then determine whether the feedback indicator flag is set. If so, then a protection switch occurs at the transmitter node so that additional packets associated with the particular virtual channel are switched in a direction opposite to the failure. A ring continuity mechanism is used to determine when to revert the transmitter nodes back to their prior operating state, and a garbage collection function is also included.

Title: Method for arc welding with melting electrode
Inventor: SOTING TOR
IPC: B23K9/073
Filed: 1998-03-03
Abstract: The present invention relates to a method of controlling a welding power source and the associated wire feed arrangement intended for arc welding operations that employ a consumable electrode, to ensure crater filling at the end of the welding operation by means of fading of the arc voltage and of the wire feed rate, respectively.

Title: Total synthesis of northebaine, normorphine, noroxymorphone enantiomers and derivatives via n-nor intermediates
Inventor: RICE KENNER CRALLE
IPC: C07D489/02
Filed: 1990-10-16
Abstract: Families of antagonist-agonists and opiate narcotics are produced from norhydrocodeinone. In a preferred embodiment, norhydrocodeinone is refluxed with sulfosalicyclic dimethylketal and delta-6-enol ether derivatives and is then converted entirely to the ether by the addition of dry tetrahydrofuran simultaneously with the removal of the thus produced ether. The ether is then reacted with methanesulfonic acid and N-bromoacetamide to form the hydrobromide salt of the 7-bromodimethylketal derivative. From this derivative, a variety of products can be derived, including the novel further intermediate 14 hydroxynorcodeinone. The present invention enables derivation using a starting material which, unlike the starting materials of prior art processes, is available in the natural (-) or synthetic (+) form. Thus, the method of the present invention provides the only known route for the synthesis of (+) forms of various derivatives and intermediates, such as (+)-7-bromo-dimethylketal nordihydrocodeinone.

Title: Compressor
Inventor: MCGRATH MICHAEL ALAN
IPC: F04B39/00
Filed: 1994-06-02
Abstract: An electromagnetic linear compressor has a linearly reciprocating piston (10) biassed in one direction by a helical coil spring. A rotational bearing (40) supports one end of the spring (20a,20b). To avoid uneven wear due to forces applied by the spring, the spring is replaced by a spring system comprising two helical coil springs (20a,20b) acting in series to bias the piston (10), and the rotational bearing (40) transmits thrust between the two springs while permitting relative rotation of the two springs about their axis. The compressor also has turbine means (30) for exerting a unidirectional rotational force to rotate the piston (10) about its axis gradually during operation of the compressor. <IMAGE>

Patent AU-7445091-A (AU)
Title: A method of forming a paper web
Inventor: HERGERT RICHARD E
IPC: D21F9/00
Filed: 1991-02-19
Abstract: A method is disclosed for forming a paper web having a low tensile ratio. The method includes the steps of ejecting stock substantially horizontally from a headbox, and receiving the rejected stock onto a substantially horizontally disposed looped first wire, moving at substantially the same speed and the same direction as the ejected stock. The arrangement is such that a first portion of water is removed from the ejected stock downwardly through the first wire during passage of the ejected stock through an initial dewatering zone. The partially dewatered stock is sandwiched between the first wire and a looped second wire, the wires defining therebetween a secondary dewatering zone for further dewatering the ejected stock. A second and third portion of water are removed downwardly and upwardly, respectively, through the first and second wires during movement of the ejected stock past a curved shoe. The curvature of the secondary dewatering zone is reversed such that the wires extend around a curved inverted box connected to a source of partial vacuum, so that a fourth portion of water is removed upwardly through the second wire into the curved box. The arrangement is such that a gradual dewatering of the ejected stock is accomplished during passage of the stock through the initial and secondary dewatering zones, thereby inhibiting removal of fines from the ejected stock and minimizing the tensile ratio of the resultant web.

Filed: 1986-12-17
Abstract: A process for making additive multilayer circuit boards wherein an insulating film (16 preferred a photo-processible film) is bonded to a pre-existing multilayer structure and selected areas of the insulating film are removed down to underlying metal sites (14) for electroless plating. All of the apertures in the insulating film are then electrolessly plated full of metal flush to the upper surface. Additional patterned composites are applied and plated up as desired to create blind vias and new conductor patterns layer by layer. In a preferred embodiment the insulating film (28) supports a patterned conductive metal foil (30) and is bonded foil pattern side down to the substrate. In an alternate process a foil clad composite is bonded to an existing substrate foil side up. The insulating layer is selectively etched through windows photoetched in the foil layer. The voids in the insulator layer expose copper sites on the underlying composite. The voids are plated full of metal to form vias and the foil layer is photoetched to make a conductor pattern.
