A sole construction having a heel carrier and an upwardly-arched heel pad. The heel pad is fitted into and supported by the heel carrier so that the heel pad provides a spring-like bending reaction to a load. The sole construction may further include a support element disposed above the heel pad and fitted into heel carrier. The support element may be upwardly-arching so that, like the heel pad, it provides spring-like bending reaction in response to a load. The support element and heel pad may be integrally formed, for example, by molding the heel pad directly onto the support element. The heel pad and / or support element may be fitted into slots in the lateral and medial sidewalls of the heel carrier to interconnect the heel pad, support element and heel carrier. The support element may have a forward extension to function as a shank.

A roll-up door seal that may be monolithically formed from a single material of uniform density. The seal is sized and adapted to assemble to a standard roll-up door frame without a separate or dedicated frame structure. The seal provides redundant sealing surfaces, positioned to cooperate with both the door and door frame, which ensure an effective and durable fluid tight seal between the cargo space enclosed by the roll-up door and the ambient environment. The seal may be produced by extrusion from a flexible, weather resistant material such as EPDM, thereby providing a low cost solution for sealing roll-up doors having industry standard door frame constructions. The seal is firmly engageable with the door frame, such that the seal may be installed with little or no secondary fixation.

In an internal combustion engine including a valve actuating mechanism, a vibration control member made of vibration control alloy is interposed in a path of vibration transmission between a camshaft and a cylinder head. The vibration control alloy has a vibration isolation capability comparable to that of rubber, but provides a durability and a resistance to degradation comparable to those of metal and alloy that are typically used in internal combustion engines. Therefore, a desired vibration control can be achieved while ensuring a required reliability, durability and resistance to degradation. The present invention is particularly useful when the valve actuating mechanism is provided with a variable lift, variable timing or variable compression mechanism because such a variable mechanism increases the stress to the engine, and tends to cause more vibrations than a more conventional non-variable valve actuating mechanism.

An opaque zone in the polycrystalline (PCA) discharge vessel of a high intensity discharge lamp may be made by creating residual pores in predetermined regions of the final-sintered discharge vessel. The control over the placement of the opaque zone is achieved by forming a carbonaceous residue in a specific region of the discharge vessel prior to final sintering. During sintering, the carbonaceous material causes residual porosity in the sintered PCA. The higher emissivity of the opaque PCA provides localized cooling in order to provide more control over the condensate behavior in the discharge vessel.

The invention relates to methods of inhibiting the expression of a PCSK9 gene in a subject, as well as therapeutic and prophylactic methods for treating subjects having a lipid disorder, such as a hyperlipidemia using RNAi agents, e.g., double-stranded RNAi agents, targeting the PCSK9 gene.

An overmolded steel flux ring member for an eddy-current fan drive assembly. The flux ring member includes a base member having a hub member, an annular outer ring member, and a plurality of connecting arm members. An overmolding material, such as aluminum, is overmolded on the annular outer ring member preferably in separate sections. Ventilation openings in said base member allow air to flow past a magnet ring for cooling.

Methods and apparatuses for masking the edges of a substrate when performing direct or reverse gravure coating using a kiss-coat configuration, particularly useful for in-line coating of biaxially oriented polymeric films. The methods and apparatuses include a masking plate configured to prevent the edge of a portion of a substrate from contacting a gravure roll, the masking plate includes a top portion having a Rockwell B hardness equal to or greater than 80, and a thickness of between 0.03125 inches and 0.375 inches. This masking plate prevents build-up of coating on the edges of the substrate which otherwise can cause film orientation production instabilities such as film breaks, sticking to tenter clips, and / or edge trim recycling incompatibilities. The masking plate provides a masking method that is effective and durable, minimizing production downtime and maintenance.

The invention discloses a method for preparing water-retaining agent by utilizing straws of farm crops. The method includes the steps as follows: after steam explosion on the straws of farm crops, adding water in straws and conducting stirring and filter pressing, wherein filter residue is straw powder material after steam explosion; adding water in the straw powder material after steam explosionfor sizing and pasting; after cooling temperature to reaction temperature, slowly adding sodium acrylate solution with 65-75% of neutralization degree, and mixing the mixture to uniform; adding initiator and cross-linking agent in sequence; and after graft copolymerization and crosslinking, obtaining graft cellulose, thus obtaining low-cost degradable water-retaining agent.

A golf green repair tool having a plurality of spears centered around a plurality of tines. The tines and spears are biased by a spring inside a housing and sleeve. When the cap the housing is pressed by the foot of a greenskeeper or golfer the spring is compressed forcing the tines and spears into the turf. The tines are inserted around the periphery of the ball-mark to aerate and loosen the turf. The spears are inserted into the center of the ball-mark and aerate and pull the bottom of the ball-mark to the level of the surrounding turf. The bottom side of the ground-contacting sleeve pressed down the raised rim of the ball-mark correcting the entire ball-mark to the level of the surrounding turf.
