摘要:
Polyurethanes, and rigid polyurethane foams in particular, are made using certain amides of modified fatty acids. The fatty acid groups are substituted hydroxymethyl, N-hydroxyalkyl aminoalkyl or hydroxy-substituted ester groups. The amide portion of the molecule contains hydroxyalkyl or other hydroxyl-substituted organic groups bonded to the amide nitrogen.

A sample collection container adapted to be connected to, and disconnected from, a sample collection adapter and a sample collection container cap. The sample collection adapter has a downward sloping interior surface that provides a free-flowing path for samples provided by a subject to the sample collection container. The sample collection adapter may have a three-dimensional rim that is curved in two different non-parallel planes.

A reinforcing system and method of fabrication for a semiconductor integrated circuit bond pad comprises a first dielectric layer or stack disposed under the bond pad; at least one second dielectric layer or stack disposed under the first dielectric layer; and a reinforcing metal structure disposed into the second dielectric layer such that the patterns of the metal structure and the second dielectric layer comprise a uniformly flat interface towards the first dielectric layer. The patterns of the metal structure and the second dielectric layer comprise feature sizes and fine pitches used in the integrated circuit.

A combined cycle waste-to-energy plant is utilized to thermally convert municipal and industrial solid wastes into essentially complete products of combustion and use the combustion heat to produce steam and/or electrical power. The plant includes a building enclosure having a waste receiving area, a waste fuel separation and processing area, an incinerator area and a heat recovery and power generation area. Processed waste fuel is delivered to a series of incinerators by an automated conveyor and hopper system, and the waste fuel is burned in the incinerators by hot exhaust gas delivered thereto from one or more combustion turbines located outside the building and drivingly connected to electrical generators. Inlet air to the turbines is drawn from with the building to maintain its interior at a negative pressure, thereby preventing waste odors and pathogens from escaping from the building. Hot combustion turbine exhaust gas delivered to the incinerators is passed through a superheater, and a portion of the exhaust gas exiting the superheater is passed through a waste heat recovery boiler. Hot combustion gas discharged from each of the incinerators is passed through an associated combusion heat recovery boiler. Gas heat recovered in the superheater and the various boilers is utilized to produce steam which operates a steam turbine drivingly connected to an electrical generator. A portion of the steam generated may also be used for process purposes.

A method and apparatus for preheating a reactor feed, comprised of an iron ore (10) and a process gas (21), in an iron carbide process for making steel is provided. The apparatus comprises a process gas preheater (40) having a furnace (56) and a heat exchanger (58). The process gas (21) is heated uniformly in tubes (117) of furnace (56) by burners (100). Excess heat generated by furnace (56) is captured by heat exchanger (58) and used to preheat combustion air (61) and ore (10).

A corner protector preferably of corrugated box board material is disclosed for ready application to the corners of an article to be shipped, such as a piece of furniture, in which the corner protectors are shipped in a flat, knocked-down configuration. The corner protector is readily assembled into its three-dimensional form so as to fit over the three intersecting planes of the article at its corners, to have a predetermined thickness so as to protect the corners of the article during shipping, and to maintain a desired spacing between the outer faces of the corner protectors and the inner faces of the shipping carton in which the article is contained.

摘要:
The cup of the present invention can have a body made of a foam material. The cup has a handle and a holder. The handle and the holder can each have a flange, respectively, to secure to the cup. The flanges, respectively, are shaped to mate with the external periphery of the cup, and can be initially held in place with an adhesive. A shrinkable wrap can then be positioned around the cup. Upon a heat treatment, the wrap shrinks to tightly engage the outside of the cup. Further, the shrink wrap maintains secure engagement between the flanges and the cup so that the handle and holder are secure. A cover can be provided for covering the cup. A package can be secured within a cavity on the top of the cover. The package can contain a fluid enabling the cup to be used for portable meals.
