20090090485MATERIAL USED TO COMBAT THERMAL EXPANSION RELATED DEFECTS IN THE METAL CASTING PROCESS - Thermal expansion defects, i.e. veining, are reduced in iron, steel, and nonferrous castings by adding a lithia-containing material in a sufficient amount to the silica sand mold. Adjusting current formulations to maximize the use of lesser expensive raw materials and minimize the use of more expensive raw materials to lower the overall percentages of lithia/metallic oxide containing additives while still reducing or eliminating thermal expansion related defects in the metal casting process reduces the overall cost to manufacture the product.04-09-2009
20090114364MATERIAL USED TO COMBAT THERMAL EXPANSION RELATED DEFECTS IN HIGH TEMPERATURE CASTING PROCESSES - An additive to foundry sand molding and core aggregates is used to produce sand cores and molds. The additive produces a sand-based foundry molding and core aggregate which resists the formation of some of the defects commonly associated with the production of castings produced by silica sand-based molding and core aggregates. In particular, the additive improves the quality of castings poured at temperatures higher than those of the pouring temperatures of molten iron, such as in steel castings, and in iron castings with “hot spots.”05-07-2009

20110313945CALL PUT REFERENCED STRUCTURES (CPRS) - Computer implemented methods, systems and computer programs for creating, managing and supporting financial instruments referred to as Call Put Referenced Structures (CPRS) as provided. CPRS units are a derivative of real estate financial options and convey the right to future compensation to the CPRS owner based on CPRS algorithms used to determine the CPRS terms and values over the life of the CPRS rather than the theoretical change in market value of the subject property. The system references associated property price indices, evaluated by the system and selected by the counterparties, based on (a) the probability that the referenced property price indices rise and fall over the term of the CPRS will correlate to the rise and fall of the theoretical market value of the subject property, (b) the secondary market liquidity of the referenced indices and (c) the ability to directly or indirectly trade the referenced indices.12-22-2011

20090177484SYSTEM AND METHOD FOR MESSAGE CLUSTERING - The disclosure describes systems and methods delivering communications associated with delivery conditions in which the occurrence of the delivery condition is determined by monitoring information received from a plurality of sources via multiple communication channels. The message delivery systems allow messages to be delivered to any “Who, What, When, Where” from any “Who, What, When, Where” upon the detection of an occurrence of one or more “Who, What, When, Where” delivery conditions. A message (which may be any data object including text-based messages, audio-based message such as voicemail or other audio such as music or video-based prerecorded messages) is delivered in accordance with delivery conditions based on any available data, including topical, spatial, temporal, and/or social data.

20120039671Apparatus For High Capacity Stone Delivery With Concentric Flow and Enhanced Nosecone For Soil Improvement - An apparatus for forming a column of compacted material in soil to increase load bearing capabilities and to provide drainage through a system having: a hopper, a stone chamber, a transition splitter pipe having at least two outlet chutes, a vibratory probe mechanism having a tip, a nosecone, and a control system; the vibratory probe mechanism has same number of chutes as the transition splitter pipe; the additional chutes are positioned along the side of the vibratory probe mechanism to increasing the flow rate of a material being discharged into a soil; the hopper is connected to the stone chamber which in turn is connected to the transition splitter pipe, the transition splitter pipe has chutes that are connected to the chutes of the vibratory probe mechanism, wherein the vibratory probe mechanism is connected to the nosecone; the control system constantly monitors the pressure of the air in the system to ensure that the chutes continuously and uniformly discharge the material; wherein the control system has one or more valves, and one or more sensors, which are interlocked together to create a pressurized air system which is necessary in order to assist the material to travel down the pipes and into the chutes and out at the tip of the vibratory probe mechanism.02-16-2012
20120039674CONTROL SYSTEM FOR MONITORING THE FLOW OF AIR IN A HIGH CAPACITY COLUMN DELIVERY DEVICE - A Control System for monitoring the flow of air in a high capacity column delivery device, wherein a programmable logic controller, uses one or more sensors for sensing changes in air pressure and an air flow in a system to ensure one or more chute continuously and uniformly discharge a material; the programmable logic controller is connected to the system having; one or more sensors and a compressor which is mechanically connected to the system to supply the air to each chute through an air hose, which is necessary in order to assist the material to travel down a pipes and into the chute and out at a tip of a vibratory probe mechanism; the system further comprises at least one air hose directed downwardly in each chute to prevent any blockage of the material; wherein the programmable logic controller monitors the flow of air and pressure of air in the system through the use of these signals and electronically decides an appropriate reaction by sends a signal to the valve and air hose; when a blockage occurs in the chute, a first signal is sent from the sensor to the programmable logic controller to make adjustments by reducing air flow from a clear chute and diverts more air to a potentially blocked chute which causes an increase in air flow and pressure of air to the potentially blocked chute; and when the blockage is cleared from the chute, a second signal is sent from the sensor to the programmable logic controller to reverse the previous operation and balances the flow of air and pressure of air to each chute.02-16-2012
