Abstract: A method to electrolessly plate a CoWP alloy on copper in a reproducible manner that is effective for a manufacturable process. In the method, a seed layer of palladium (Pd) is deposited on the copper by an aqueous seeding solution of palladium acetate, acetic acid and chloride. Thereafter, a complexing solution is applied to remove any Pd ions which are adsorbed on surfaces other than the copper. Finally, a plating solution of cobalt (Co), tungsten (W) and phosphorous (P) is applied to the copper so as to deposit a layer of CoWP on the Pd seed and copper.

Abstract: A manual ice and snow melting device comprising a container assembly and a handle assembly. Ice and/or snow is broken up by pegs attached to the container assembly. An ice and snow melting substance, like salt, is inserted into the container assembly and disbursed into the broken pieces of ice and/or snow through apertures in the container assembly. The device is manually operated and can be easily maneuvered on virtually any surface covered with ice and/or snow.

The apparatus comprises an automated polarized light microscope combined with means for achieving spectroscopic analysis. The apparatus may optionally include means for spectral imaging associated with the means for achieving spectroscopic analysis. Any means for achieving spectroscopic analysis may be utilized for example Raman, mid-infrared, near-infrared, ultraviolet, visible, luminescence, and the like.

Abstract: An electronic presentation system and method provides multiple display screens for presentation materials as well as permits dynamic annotations to presentation materials that do not permanently alter the presentation materials. In a multi-windowed display interface, a currently displayed slide or the next-to-display slide can be easily annotated or otherwise modified. Thus, the presentation materials can easily be directed to any one of the display screens and any annotations can be saved for future use or simply deleted.

Abstract: The present invention is a nutrient delivery system including a protein source and, optionally, a fiber source. Extruding proteins disrupts the protein structure at the secondary level, rendering the protein relatively inert as compared to an unextruded protein. Because the extruded protein is relatively inert, it can be incorporated in relatively large amounts in food products without substantially adversely affecting the food product. In addition, the protein source can be coextruded with a fiber source to provide an extruded protein-fiber blend. The extruded protein-fiber blend of the present invention permits the inclusion of high levels of protein and fiber into a food product substantially without adversely affecting the food product. The nutrient delivery system of the present invention can be used to prepare food products that meet US FDA and other regulatory guidelines for food nutrition labeling.

Abstract: An anti-roosting device is disclosed. The device includes a track, an electrical conductor, and an electrical source. The conductor is embedded within the track, with a portion of the conductor left exposed. The electrical source provides low amperage at high voltage to the electrical conductor such that the device is harmless to both birds and humans, but will deliver a shock that is effective in keeping birds from roosting thereon.

Abstract: A structure incorporates very low dielectric constant (k) insulators with copper wiring to achieve high performance interconnects. The wiring is supported by a relatively durable low k dielectric such as SiLk or SiO2 and a very low k and less-robust gap fill dielectric is disposed in the remainder of the structure, so that the structure combines a durable layer for strength with a very low k dielectric for interconnect electrical performance.

Abstract: An integrated circuit structure is disclosed that has a layer of logical and functional devices and an interconnection layer above the layer of logical and functional devices. The interconnection layer has a substrate, conductive features within the substrate and caps positioned only above the conductive features.

Abstract: Disclosed are modeling and process control techniques for manufacturing products. More specifically, computer-aided modeling techniques are described that allow the manufacturer to predict a profile for a multivariate output that is necessary to achieve a target performance property for a manufactured product.

Abstract: A chiller system includes at least two refrigerant circuits. In a low ambient temperature condition, only one refrigerant circuit is activated, but its condenser fan is de-energized. To provide some airflow across the condenser of the activated circuit, a condenser fan of the inactive circuit is energized. A small air duct allows the condenser fan of the inactive circuit to draw a low volume of air across the condenser of the active circuit.

Abstract: An evaporator for a refrigeration chiller includes a tube bundle in which at least a portion of the tubes of the tube bundle are immersed in a pool which include both liquid refrigerant and is lubricant. Liquid refrigerant and lubricant are deposited into the pool at a first pool location. Because of the vaporization of refrigerant that occurs within the pool, a pattern of flow is established and managed that causes the lubricant in the pool to migrate from the location of its deposit into the pool to a second pool location. An outlet is provided at the second pool location from which lubricant is drawn out of the evaporator.

Abstract: A heat exchanger comprising: a plurality of longitudinally extending tubes grouped into at least first, second and third passes; the tubes in the first pass being serially connected with tubes in the second pass; the tubes in the second pass being serially connected with tubes in the third pass; and wherein the number of tubes in the first pass is greater than the number of tubes in the third pass.

Abstract: A method of controlling an expansion valve including the steps of: measuring a primary system condition; determining an error in the primary system condition; measuring a secondary system condition; determining an error in the secondary system condition; and modulating the expansion valve based upon the larger of the first or second error.

Abstract: An assured supply of lubricant to the compressor in a refrigeration chiller is provided by a reservoir that is connected in parallel with the main line by which lubricant is supplied to the compressor. The reservoir is connected to the main lubricant supply line in a manner such that if the lubricant supply line is blown dry, as can occur as a result of an unusual or abnormal chiller shutdown condition, a critical portion of the supply line will be refilled by the reservoir relatively very quickly which assures the immediate availability of lubricant to the compressor from that portion of the lubricant supply line when it next starts up.

Abstract: A method of controlling compressor minimum capacity. The method comprises the steps of: measuring a first condition; comparing the first condition to a first setpoint to determine a first conditioned error; modulating compressor capacity relative to the first condition error; measuring a second condition; comparing the second condition to a second setpoint to determine a second condition error; and modulating compressor capacity relative to the second condition error if the magnitude of the second conditioned error is greater than the magnitude of the first conditioned error.

The system comprises a compressor having a discharge and including at least one rotor and at least one bearing; a lubrication system including at least one oil recovery device for recovering oil from the compressor, and further including bearing conduit connecting the oil recovery device to the compressor bearing and including rotor conduit for connecting the oil recovery device to the compressor rotors; and an oil protection system. The oil protection system includes a compressor discharge temperature sensor located in the discharge for sensing the temperature of a lubricant/refrigerant mixture discharged by the compressor, a differential pressure sensor located in the bearing conduit for measuring a differential pressure in the bearing conduit, and an oil detector located in the rotor conduit for detecting the presence of oil in the rotor conduit.
