Abstract: A hybrid reinforcing fabric includes glass fibers and carbon fibers. The hybrid reinforcing fabric can be readily infused at an acceptable infusion speed, without requiring that the carbon fiber tows used to form the hybrid reinforcement fabric be spread or pre-impregnated with resin. Thus, the fabric provides for an effective one-step (i.e., in the mold) infusion process during composite part formation.

Abstract: In some examples, a system determines, based on information relating to access of objects in storage segments by requester devices, an affinity between access devices and the storage segments that are managed by respective controllers of a plurality of controllers, the access devices comprising the requester devices or the controllers. The system selects, based on the affinity between the access devices and the storage segments, a controller of the plurality of controllers for serving requests of a first requester device of the requester devices to access objects.

Abstract: A polymer foam is provided. The polymer foam is formed from a composition that includes a polymer, 2% to 10% by weight nano-crystalline cellulose based on the total weight of the polymer foam, and at least one blowing agent. The polymer foam exhibits a reduced thermal conductivity (k-value) and a higher water vapor permeability as compared to an otherwise identical polymer foam without nano-crystalline cellulose.

Abstract: Examples described herein include receiving a request for a clone of a directory tree in a distributed file system for the directory tree at a first point in time. Examples described herein also include generating a copy of an inode data and determining a relevancy of the clone based on a birth epoch and a death epoch of a first entry in the inode data. The inode data may describe a root of the directory tree at a second point in time.

Abstract: A plurality of segment sets of one or more storage segments of a distributed file system may be created and/or updated. The storage segments may be independently controlled. A placement policy may be assigned to each of the plurality of segment sets. The placement policy may control an initial placement and/or relocation of an object to the one or more storage segments for the assigned storage set.

Abstract: A vacuum insulated panel includes a fiberglass insulation blanket and a barrier layer. The barrier layer is sealed around the fiberglass insulation blanket. Gas inside the barrier layer is evacuated such that the fiberglass insulation blanket is compressed.

Abstract: Roof systems and related method having a roof deck, a plurality of shingles, and a plurality of fasteners, having a material that partially changes state and displaces into the roof deck material to secure the fasteners and shingles to the roof deck. The shingles can be positioned in an overlapping pattern, and the fasteners can have first portions configured to penetrate into the roof deck and can have at least one material that melts at a threshold temperature. The first portions of the fasteners extend through one or more shingles and penetrate into the roof deck, where the material of the first portion of the fasteners increases in temperature above the threshold temperature, partially changing into a more flowable state, and displaces into voids in the material of the roof deck. Second portions of the fasteners engage the upper surfaces of the shingles to secure the shingles to the roof deck.

Abstract: A duct insulation laminate an insulation layer and a facing. The insulation layer includes an insulation layer having a first edge surface, a second edge surface that is spaced apart from the first edge surface, a first face surface that extends from the first edge surface to the second edge surface, and a second face surface that is opposed to and spaced apart from the first face surface. The second face surface extends from the first edge surface to the second edge surface. The facing is attached to the first face surface, and includes a polyester blended non-woven veil defining an outermost exterior surface of the duct insulation laminate.

Abstract: A roofing shingle includes a buttlap portion with a butt edge and a headlap portion with a head edge. The roofing shingle includes a coated mat which is a roofing mat coated with an organic-based coating material. The roofing shingle also includes a water impermeable sheet adjacent to the coated mat. In one embodiment, the headlap portion of the coated mat is mostly replaced by the sheet. In another embodiment, the roofing shingle has a limited width. In a further embodiment, the roofing shingle is reduced in weight compared to a conventional shingle.

Abstract: A roofing shingle comprising a mat having regions of various thicknesses. A layer of asphalt-based material coats the mat and a layer of granules is deposited on the asphalt-coated mat. The variations in the thickness of the regions of the mat give the shingle differences in thickness corresponding to the thickness variations in the regions of the mat, thereby giving the shingle an appearance of depth.

Abstract: An electrical terminal block assembly including a housing having one or more terminals, each of the terminals including a terminal assembly having a resilient member and a contact surface configured to releasably secure a conductor within the terminal and an operating lever removably hinged to the housing, the operating lever being configured to interface with the resilient member for increasing a distance between the resilient member and contact surface to allow passage of a conductor between the resilient member and contact surface.

Abstract: Provided are alternative fabrication methods and compositions for an electrochemical cell. The methods and compositions of the present invention are particularly, though not exclusively, applicable to the manufacture of polymer-cased lithium-ion secondary battery cells. Briefly, the present invention provides an electrochemical cell fabrication process wherein a PVDF-based binder specifically selected for its physical and chemical properties, in particular, it's high crystallinity, is coated on a porous separator material to form a porous separator. The high crystallinity PVDF of the binder results in improved cell structure and performance.
