  • Patent number: 9928118
    Abstract: Monitoring resource allocation requests to computer resources shared between a plurality of computers includes detecting an allocation request by an application for a first set of the plurality of computer resources and assigning the application to a group, wherein each member of the group comprises a respective application having an associated allocation request for an associated set of the plurality of computer resources. Determining that the first set of the plurality of computer resources cannot be allocated by the application, and determining that the first application generates a function call instructing other members of the group, if any, to request allocation of their associated set of the plurality of computer resources results in incrementing a counter value corresponding to the group. A message is sent when the counter value exceeds a predetermined threshold.

  • Patent number: 9306894
    Abstract: Managing computer resource allocation includes detecting, by one computer amongst a plurality of computers, generation of an allocation request, wherein the allocation request requests exclusive access, by the one computer, to a computer resource shared between the plurality of computers; determining a period of time that has elapsed since detection of the generation of the allocation request; determining that a delay has occurred when the period of time has exceeded a predetermined threshold; and then, transmitting, by the one computer, a delay message based on the delay to each of the plurality of computers.

  • Patent number: 9212021
    Abstract: Winding cores for elastically stretched or shrinkable materials are designed to significantly reduce the amount of roll strain energy developed during winding. This is accomplished by building into the core an energy-absorbing zone that can be collapsed by a substantial amount and in a relatively controlled fashion over a substantial period of time under the influence of a continued radially inward pressure exerted by the roll of wound material. The energy-absorbing zone is formed by one or more collapsible layers having repeated atomic regions projecting out of a plane of the sheet and each defining a plurality of normal vectors in different sub-regions of the atomic region, wherein the normal vectors, when projected onto the two-dimensional plane of the sheet, are in a plurality of different directions in the plane.

  • Patent number: 8329268
    Abstract: A paper-based plant pot comprises a container formed from a sheet of paper-based material wrapped about an axis, opposite edge portions of the sheet being secured to each other, the container having a side wall that encircles the axis and a bottom wall formed by a plurality of bottom panels of the sheet folded inwardly from a lower edge of the side wall and engaging one another. The sheet comprises a paperboard substrate formed of natural cellulose fibers, an internal sizing composition incorporated into the paperboard substrate so as to render the paperboard substrate substantially resistant to saturation by liquid water, and a thermoplastic polymer layer on one of the major surfaces of the paperboard substrate. The thermoplastic polymer layer faces an interior of the container and forms an inner surface thereof for contact with soil or other growing medium placed in the container.

  • Patent number: 8084108
    Abstract: A core having enhanced ID stiffness is provided. The core includes inner, intermediate, and outer wall zones. The intermediate zone is spring-like in that it minimizes deformation of the inner zone from a radial deflection of the outer zone by absorbing at least some of the deformation. Similarly, the intermediate zone minimizes deformation of the outer zone from a radial deflection of the inner zone by absorbing at least some of the deformation. The intermediate zone includes at least first and second intermediate layers and one or more intermediate support layers. The first and second layers include a number of plies and gaps that are offset from each other, i.e. the plies of the first layer are radially aligned with the gaps of the second layer. The intermediate support layers are between the first and second layers and extend radially across the gaps of the first and second layers.

  • Patent number: 7842362
    Abstract: A wound paperboard tube having enhanced burst strength in high-moisture conditions up to and including complete and prolonged submersion in liquid water comprises a plurality of paperboard plies formed from a pulp comprising papermaking furnish and an effective amount of a size such that the paperboard plies have reduced moisture add-on when submerged in water, relative to paperboard plies formed from a pulp comprising the identical furnish but without the size. The plies are wound one upon another about an axis of the tube and adhered together with a water-resistant adhesive comprising a polyvinyl composition containing a cross-linking agent for inducing cross-linking of the adhesive.

  • Publication number: 20040244909
    Abstract: The present invention relates to activatable webs having fibrous substrates coated with activatable adhesive and methods of forming the webs into articles by indirectly activating the adhesive using microwave energy. The activatable web may further include a protective coating of a material that is compatible with the adhesive. One or more activatable webs can be formed into the shape of an article such as by wrapping the activatable webs around a mandrel. The activatable webs can be subjected to microwave energy shortly before being formed into the shape of the article or while they are held in the appropriate shape. The microwave energy is absorbed by moisture retained within the fibrous substrate, which becomes heated. The heated moisture activates the adhesive, causing it to bond to any webs in which the activatable web has been brought into contact and to stiffen.

  • Patent number: 5106356
    Abstract: The invention provides a method and apparatus for the manufacture of helically wound paperboard tubes having a highly uniform outside diameter. The method of the invention involves the application of controlled compressive force to at least one of the paperboard plies fed to a helical winding operation in order to control the thickness of the ply or plies and thereby control the outside diameter of the helically wound tube. In one preferred apparatus embodiment of the invention, the compressive force applied to the paperboard ply is applied via a pair of cooperating compression rolls. The nip between the two cooperating rolls is controllably varied by mounting one of the rolls for rotation about a shaft which is rotatable about an eccentric axis which is parallel to and offset from the axis of rotation of the roll. The rotation of the shaft thus causes the roll to move toward or away from the other cooperating roll and thereby varies the nip spacing between the rolls.
