Abstract: A wavelength is selected for use in transmitting optical data along a path in an optical network. Wavelengths that are available for use end-to-end along the path are found, the wavelengths that are available on each link attached to each node on the path are found and a wavelength that is available end-to-end and that is more available on the links attached to the nodes is selected.

Abstract: A path is established through an optical communications network. One or more partial paths are evaluated according to a first criterion, and candidate end-to-end paths are then evaluated according to a second criterion. The end-to-end path evaluation disregards candidate end-to-end paths that include partial paths not meeting the first criterion. A path is established by selecting one of the candidate end-to-end paths on the basis of the second criterion.

Abstract: An address resolver system that assists a node in an IPv6 network to select an address for connectivity with a node in an IPv4 network when both DSTM and NAT-PT transition mechanisms are available. Native connectivity can be achieved by preferring an encapsulation or tunnelling mechanism such as DSTM where possible over a translation mechanism such as NAT-PT. A range of encapsulation and translation mechanisms are envisaged. The resolver determines capabilities of the node and of the application that requires the address in order to make the selection.

Abstract: A tunnel is established across an IPv4 domain for the transport of packets from a source host on one IPv6 domain to a destination host on another IPv6 domain, there being respective interfaces between the IPv4 domain and the IPv6 domains.

Abstract: Embodiments of the present invention relate to coordinating address allocation events at a routing device and at a host machine, where the routing device is arranged to route data between the host machine and at least one other host machine. The routing device may be a router and the host machine may be a computer located in a first network, the first network operating in accordance with a first transmission protocol. The other host machine may be a computer, located in a second network, the second network operating in accordance with a second transmission protocol. The method is particularly suited to situations where the host machine is running one or more applications in accordance with the second transmission protocol. Embodiments of the invention are concerned with coordinating address allocation events that are required to enable data of the second transmission protocol to be transmitted through the first network and on to the other host machine.

Abstract: A greeting card has on its front surface a picture frame formed of a single, integral piece of magnetic sheeting. The magnetic sheeting picture frame is held to the front of the card by adhesive which will release the frame when the frame is pulled away with a small amount of force. The one-piece integral frame has a central opening for cropping and displaying a photograph or other picture on the front of the greeting card, inserted between the front of the greeting card and the back of the magnetic frame. The releasable adhesive can be in contact with the back surface of the frame along three legs but not along the fourth, so that a purchaser of the greeting card can slide a picture down between the card and the frame. Alternatively, the adhesive can contact all four legs of the back surface of the frame, with the frame to be pulled off and replaced by the purchaser to retain a picture behind the frame.

Abstract: A pallet rack system has a safety lock on end connectors of horizontal beam members to prevent accidental removal of the horizontal beams from the vertical frame supports. The safety lock includes a cross-shaped member rigidly secured to the beam connectors and a U-shaped member associated with the cross-shaped member to operatively couple the U-shaped member with the end connector. The U-shaped member includes a hook which cooperates with an aperture in the frame supports to lock the safety lock device to the frame support which, in turn, locks the horizontal beams with the vertical frame supports.

Abstract: A hollow, tubular, elongated beam is made by roll-forming an elongated strip of sheet metal into a generally rectangular cross-section shape with its opposite edge portions overlapped to form a double ply beam wall along one side of the beam. The plies are adhesively secured together by an adhesive material inserted between them. The sheet metal is initially rolled into a U-shaped channel having a base and opposite walls. An integral, interior ledge is formed in, and extends along the length of, one of the channel walls. Then, the edge portion of the opposite channel wall is bent to form an inner ply that overlaps and closes the open channel, to form the tubular shape, with its free edge abutted against the ledge. Next, the free edge of said one channel wall is bent to form an outer ply around and overlapping the inner ply, with the abutted inner ply free edge and ledge serving as a support for the bending of the outer ply. The adhesive is inserted between the plies when the outer ply is bent.

Abstract: A frame type, heavy duty storage rack corner post is formed of sheet metal which is bent into a rear wall, integral side walls and front wall sections that are spaced apart to form a central slot extending the height of the post. The free edges of the front wall sections are bent outwardly to form a pair of parallel base walls which terminate in oppositely extending flanges, so that the front wall sections, base walls and flanges form oppositely opening, aligned vertically extending channels along the height of the post. The channel base walls are provided with a series of holes, with the holes in one aligned horizontally with the holes in the other. The channels are of a width to snugly receive a nut so that a screw may be inserted through a pair of aligned holes and threadedly engaged with the nut for turning the screw while the nut is held stationary by the channel walls.

Abstract: In a frame type rack having horizontal beams whose ends are adjustably fastened to vertical posts by headed pins that extend into holes formed in the posts, a latch is provided that prevents inadvertent release of the beam pins from the holes in the post. The post holes are widened at their tops for insertion of the pins and narrowed at their bottoms to engage and prevent removal of the pins therefrom. The latch includes a plate, which is fastened to the end of the beam, and upon which three vertically aligned pins are secured for extending into corresponding holes in the post. A cover strip overlaps the plate and the upper pin which, also, rigidly secures the cover strip to the plate. A slidable spring member is held between the inner portion of the cover strip and the plate and extends beneath it. Vertical openings in the spring member receive outer end portions of the middle and lower pins.

Abstract: A hollow, tubular beam is formed of an outer and an inner, U-shaped, elongated, roll-formed, sheet metal channel which are telescopically interfitted. The overlapping adjacent leg portions of each channel are provided with an inwardly bent rib and groove mechanical connection, but the curvature of the adjacent rib and groove surfaces are slightly different to provide a number of longitudinally extending, separated spaces therebetween. The free edge of one of the legs of the outer channel is bent normally to cover a corresponding corner-like shoulder bent in the adjacent inner channel leg. The radii of the flange and shoulder bends are slightly different to provide a slight, longitudinally extending space between them. Also, overlapping leg portions are spaced apart by integral embossments formed on the legs. The adjacent channel legs are adhesively bonded together by an adhesive material applied within the spaces.

Abstract: A stabilizing device for infant pacifiers is constructed of an elongated generally tubular bean bag, closed or closable at two locations to form a central and two outer bean bag sections. On the center section is a fabric tab for inserting through the ring of a pacifier and then securing to the bean bag with hook and loop fasteners. The bean bag sections lie on the infant's chest or shoulders or on a surface to retain the pacifier within reach even when it is not in the baby's mouth. With adjustment of the positions of the two outer bean bag chambers, a variety of configurations can be formed to stabilize the pacifier in different positions of the infant.
