Abstract: Methods of operating an SIP load balancer, one or more SIP server nodes and/or one or more SIP server instances are provided that efficiently manage a processing load. Configurations for an SIP load balancer, one or more SIP server nodes and/or one or more SIP server instances to enable efficient management of a processing load are also described. In certain ones of these, state data for a set of SIP processes may be sent from a SIP server instance and used by a SIP load balancer to remove inactive SIP processes from a data structure. The management of a processing load comprising a number of SIP processes following the failure of a SIP server node and/or a SIP server instance is also provided.

Abstract: A method and apparatus for applying nail tabs to roofing and building cover materials involving the steps of depositing tab material onto the surface of the roofing or building cover material, during or after its manufacture, resulting in a plurality of nail tabs from a lamination roll, and bonding the tabs to the surface of the material by pressure between the lamination roll and said surface. The method also encompasses depositing the tab material or pre-formed tabs by a pressure roll in contact with said surface. The tabs preferably are made substantially of a polymer material and may be hardened or cured by ultra-violet or visible light. The tabs may also be pre-formed and have adhesive backing.

Abstract: A method of making a composite roofing material and the resulting material by depositing nail tabs made of a thermoplastic, thermosetting, adhesive or elastomer material, in a liquid state, onto the base substrate of the composite roofing material or onto the saturated or coated roofing material, or onto a transfer surface to be pressed or laminated onto the roofing material. A preferred embodiment transfers the nail tabs onto an engraved transfer impression roll and uses a pressurized applicator to inject the viscous tab material into engraved patterns depressed in raised areas of the impression roll., then deposits the material onto the roofing material. A preferred embodiment also includes the thermoplastic or thermosetting material in a liquid or viscous state hardened or cured by either its exposure to the air or by the use of ultra-violet or visible light.
