Apparatus and method for cooling electrical components of a computer
Patent No. 9,075,581
A plenum for guiding a flow of cooling air through the interior of a computer is designed to maximize the airflow over those electrical components within the computer which are most sensitive to temperature, and/or which require the greatest amount of cooling. The plenum is designed to be mounted over top of a computer motherboard which includes a plurality of electrical components mounted thereon. One or more apertures are formed in the lower wall of the plenum so that electrical components mounted on the computer motherboard can protrude through the apertures and into the interior of the plenum. The lower surface of the plenum is designed to prevent the flow of cooling air passing through the plenum from escaping through the apertures on the lower wall. Also, upper and lower protrusions on the plenum can extend into the interior of the plenum to concentrate the flow of cooling air onto the electrical components which are protruding through the apertures and into plenum.

Multilayer sealant film
Patent No. 9,073,674
A multilayer film suitable for sealing containers such as used for food packaging, and methods of making the film, are described. The film is particularly suitable for sealing containers made from polylactic acid (PLA). The multilayer film includes: a) a substrate that includes a polymeric base layer; and b) on the substrate, a heatseal layer containing a PLA homopolymer or copolymer. The heatseal layer further includes dispersed therein an adhesion promoter, or alternatively the substrate further includes the adhesion promoter in a layer on a surface of the polymeric base layer between and adjacent the base layer and the heatseal layer. An antifog agent may also be included in the heatseal layer or on the surface of the heatseal layer opposite the substrate.

Pre-portioned moist product and method of making
Patent No. 9,072,318
A pre-portioned moist product comprising a portion of plant material and a coating is disclosed. Preferably, the plant material comprises tobacco. The coating includes a soluble, non-cross-linkable component and an cross-linkable component which becomes substantially water-insoluble upon crosslinking. The soluble component of the coating dissolves upon placement in the mouth, while the insoluble component disintegrates and/or loses structural integrity once the soluble component has dissolved to release and disperse the plant material in the user’s mouth.

Multilayer structure useful for electrical insulation
Patent No. 9,073,290
A multilayer structure particularly useful in a transformer which contains (a) a first layer of aramid and cellulose wherein (i) the aramid is present as an meta-aramid in an amount of 0 to 50 weight percent floc and 50 to 100 weight percent fibrid, (ii) the cellulose is present in the form of cellulosic pulp fiber and (iii) the aramid is present in an amount of 16 to 75 weight percent and the cellulose is present in an amount of 25 to 84 weight percent, said percentages on the basis of the aramid and cellulose and (b) a second layer containing cellulosic pulp fiber with the proviso that the second layer does not contain aramid.

On-line oil and foreign matter detection system and method
Patent No. 9,073,091
A system for detecting oil contaminated product and foreign matter within a product stream is provided. The system includes a first conveying means for delivering a product stream; a first detection apparatus for detecting oil contaminated product, the first detection apparatus positioned proximate the product stream, the first detection apparatus including a high intensity infrared light source directed at the product stream; and a high speed NIR spectrometer sensor tuned to detect a reflected signal from a taggant disposed in the oil of the oil contaminated product; a second detection apparatus for detecting foreign matter within a product stream, the second detection apparatus positioned proximate the product stream, the second detection apparatus including a light source for illuminating the product stream and a detector for detecting light reflected from the product stream; and a controller for determining whether the product stream contains oil contaminated product or foreign matter.

Grill buddies
Patent No. 9,074,944
A thermal indicator device is disclosed for providing an indication that an article of food is heated to a certain level of preparedness. The thermal indicator device comprises a stake and a marker secured to the stake. The stake comprises an end adapted for insertion into the food. The marker is adapted for movement between a retracted position and an extended position. The marker is retained in the retracted position via a string, and actuated to the extended position via an internal spring. Accordingly, at a temperature below the melting temperature, the string maintains the marker in the retracted position, and when the internal temperature of the food rises to a temperature equal to or higher than the melting temperature, the string melts to permit release of the marker into the extended position. Once the string melts, the internal spring actuates the marker into the extended position for visual indication.

Method for removing sulfur from fiber using monovalent salt ion exchange
Patent No. 9,080,261
The present invention concerns methods for removing sulfur from a fiber made from a polymer comprising imidazole groups, said method comprising: a) contacting never-dried sulfate anion containing polymeric-fiber with aqueous salt having monovalent anions to displace at least a portion of the sulfate anions; and b) rinsing the fiber to remove displaced sulfate anions.

Low shrinkage, dyeable MPD-I yarn
Patent No. 9,080,260
The invention relates a heat-treated poly(metaphenylene isophthalamide) polymer fiber having a crystalline structure as represented by a carbonyl stretch peak at a wavelength of 1,650 cm-1 in a Raman spectra response which before coloration with a dye, shrinks linearly 0.4 percent or less when exposed to 285 degrees Centigrade for 30 minutes; and which after contact with an aqueous red dye solution for 1 hour at 120 degrees Centigrade, has an “L” value coloration of at least 40 units lower than the “L” value of the fiber before coloration.

Cigar box with pedestal lid
Patent No. 9,079,702
A cigar box includes a pedestal lid and a base. The base includes front, rear and side panels and a bottom panel. The lid includes a top panel and a front panel. Side edges of the lid are slidably insertable into channels in opposing interior surfaces of the side panels of the base. In a first configuration, the top panel is inserted into the base to close the cigar box. In a second configuration, the lid is removed from the base and placed underneath the bottom panel of the base such that the base is inclined towards its front panel lower. In this configuration, gravity causes cigars within an interior volume of the base to roll downwardly to the front of the base, where an opening in the front panel of the base facilitates their removal.

Menthol cigarette
Patent No. 9,078,470
Cigarettes are provided which contain a filtering system and flavorants encapsulated with polyvinyl acetate, wherein deactivation of a sorbent by the flavorant is reduced through the encapsulation of the flavorant within the polyvinyl acetate. A preferred flavorant is menthol. The encapsulated flavorants are prepared by mixing at least one flavorant with polyvinyl acetate and a solvent, such as ethanol, and forming the encapsulated flavorants. Methods of making cigarettes and smoking the articles are also provided.
