Abstract: A locking push pin and methods of using the locking push pin to assemble a heatsink assembly, are described. The locking push pin includes a body lumen extending through a pin body, and several prongs radially outward from the body lumen. Peripheral surfaces of the prongs are separated by a body slot radially outward from the body lumen. The locking push pin includes a pin lock having a branch that extends through the body lumen and into the body slot between the peripheral surfaces. The pin lock advances from an unlocked configuration in which the branch is in the body slot proximal to a distal end of the prongs, allowing the prongs to deflect radially inward, to a locked configuration in which the branch is in the body slot at the distal end of the prongs, blocking deflection of the prongs. Other embodiments are also described and claimed.

Abstract: A heatsink retainer assembly, and components of the heatsink retainer assembly, are described. The heatsink retainer assembly includes one or more heatsink anchors mounted on a heatsink retention wire between several stops. The anchors include channels to receive the retention wire such that the anchors can slide over the retention wire between the stops. The stops retain the anchors on the retention wire. The anchors can be inserted into respective mounting holes of a carrier substrate by pressing the anchors into the mounting holes on a side of the carrier substrate carrying a heat source. A heatsink can be mounted on the heat source and the retention wire can extend over the heatsink to retain the heatsink against the heat source when the anchors are secured to the carrier substrate. Other embodiments are described and claimed.

(260° C.) or greater, and hot hydrochloric acid having a temperature of about 300° F. (150° C.) or greater. The ability to protect a wearer from heat from hot high heat capacity materials and/or hot corrosive materials is quite different from simply shedding liquids, even flammable liquids, such as gasoline is unexpected.

Abstract: A composite fire-resistant and heat blocking article. The article includes at least two layers of a fire-retardant and heat-resistant fabric with a heat-barrier and/or heat-absorbing core material disposed between the fabric layers. The composite fire-resistant and heat blocking article provides durability, fire resistance, and the ability to withstand high heat exposure on one face for an extended period of time without transferring significant heat to the opposite face. Combining fire-retardant fabrics with a heat-barrier and/or heat-absorbing core material achieves a true synergy by offering greater fire and heat protection to persons and structures than either component can offer alone.

Abstract: Fire retardant and heat resistant yarns and fabrics include an inner core comprised of oxidized polyacrylonitrile encapsulated by an outer shell comprised of a liquid-resistant and strengthening polymer material. The liquid-resistant and strengthening polymer material includes one or more types of cured silicone polymer resin. A fluorchemical may be at least partially impregnated into the inner core prior to applying the liquid-resistant and strengthening polymer material in order to further enhance the liquid shedding properties of the yarns or fabric. Because the silicone polymer resin only encapsulates the yarn, but does not form a continuous coating over the whole fabric, the treated fabric is still able to breath through pores and spaces between individual yarn strands that make up the fabric. The liquid-resistant and strengthening polymer material increases the strength, abrasion resistance, durability and liquid and gel shedding capability of the fire retardant heat resistant yarn or fabric.

Abstract: Fire retardant and heat resistant yarns, fabrics, and other fibrous blends incorporate one or more fire retardant and heat resistant strands comprising oxidized polyacrylonitrile and one or more strengthening filaments such as metallic filaments (e.g., stainless steel), high strength ceramic filaments, or high strength polymer filaments. Such yarns, fabrics, and other fibrous blends have a superior tensile strength, cut resistance, abrasion resistance, LOI, TPP and continuous operating temperature compared to conventional fire retardant fabrics. The yarns, fabrics, and other fibrous blends are also more soft, supple, breathable and moisture absorbent and are therefore more comfortable to wear, compared to conventional fire retardant fabrics. The inventive yarns may be woven, knitted or otherwise assembled into a desired fabric or other article of manufacture.

Other components (e.g.

Abstract: Fire retardant and heat resistant yarns, fabrics, felts and other fibrous blends which incorporate high amounts of oxidized polyacrylonitrile fibers. Such yarns, fabrics, felts and other fibrous blends have a superior LOI, TPP and continuous operating temperature compared to conventional fire retardant fabrics. The yarns, fabrics, felts and other fibrous blends are also more soft and supple, and are therefore more comfortable to wear, compared to conventional fire retardant fabrics. The yarns, fabrics, felts and other fibrous blends incorporate up to 99.9% oxidized polyacrylonitrile fibers, together with at least one additional fiber, such as p-aramid, in order to provide increased tensile strength and abrasion resistance of the inventive yarns, fabrics, felts and other fibrous blends. The yarns may be woven, knitted or otherwise assembled into a desired fabric.

Abstract: A method for curing low k dielectric materials uses very short, relatively high temperature cycles instead of the conventionally used (lower temperature/longer time) thermal cycles. A substrate, such as a semiconductor wafer, coated with a layer of coating material is heated to an elevated temperature at a heating rate of greater than about 20° C. per second. Once the coating material has been converted to a low dielectric constant material with desired properties, the coated substrate is cooled. Alternatively, spike heating raises and promptly lowers the temperature of the coated substrate to effect curing in one or a series of spike heating steps. The method allows for a thinner refractory barrier metal layer thickness to prevent copper diffusion, and uses shorter curing times resulting in higher throughput.

Abstract: A hydratable packet pad (10) comprising a series of spaced, packet cells (17) made up of a backing sheet (11), preferably of an impervious plastic sheet material, e.g., polyester film, and an upper, porous, sheet (12) permeable to water, of, for example, non-woven polypropylene without any additive(s), with a tacky sealant (13), [e.g., 22.5% ethylene-methyl-acrylate (EMA)], used to affix and seal the two sheets together in a process forming the cells and to initially hold the polymer powder in the cell areas, which are initially deposited on the film in a squat cone, prior to the cells being formed. Within each cell of the packet is a superabsorbent polymeric material (14) of a multiply-cross-linked polymer, for example, a doubly cross-linked sodium polyacrylate polymer. The superabsorbent material also preferably includes no alcohol (OH) functional groups, and the sheeting materials preferably contain no cellulose materials.

Abstract: A reverse cantilever spring clip for providing intimate thermal contact between a heat sink and a heat generating electrical component such as an integrated circuit (IC). The spring clip includes a spring member and a retention member. The retention member has one or more legs with a securing member affixed to an outer end of the legs. The legs are configured for engaging a heat sink and a circuit board to which the IC is mounted so that the heat sink is positioned directly over the circuit board. The securing member maintains contact between the IC and heat sink.

Abstract: Apparatus for preparing packaging materials for use in shipment of heat sensitive materials, utilizes a hydration module, a freezing module, and a delivery module. Rolls of superabsorbent polymer based refrigerant media in the form of a continuous web of a selected length and width are maintained in dry storage. These may be cut to size along the web material which separates cells containing the super absorbent polymer or may be precut by the manufacturer into pads of desired sizes. The web or pad is advanced into the hydration module which comprises a dip tank or spray system to provide an adequate supply of hydrating fluid to the superabsorbent polymer. The absorbed fluid fills the cells of the web. The hydrated web is then conveyed into a freezing chamber having a temperature of -10 degrees Fahrenheit, or lower, where the fluid absorbed within the cells freezes. The frozen material then exits the freezing chamber.
