20090205164 | Castor Wheel Assembly - A castor wheel assembly comprises a tubular casing of rectangular cross section extending in axial direction between a pair of opposed ends and a swivel member for connecting the casing to an object supported thereon for relative rotation about a vertical swivel axis. A shaft extends horizontally through the casing for connection to pivot arms at opposed ends thereof. A castor wheel is coupled between the pivot arms spaced radially outwardly from the shaft. A flange spans radially from the shaft a fully width of the casing along a length of the shaft. Elastomeric material supports the shaft and the flange along one wall of the casing such that the elastomeric material is arranged to be compressed between the flange and an opposing wall of the casing by rotation of the shaft resulting from upward deflection of the wheel relative to the casing. | 08-20-2009 |

20140201187 | System and Method of Search Indexes Using Key-Value Attributes to Searchable Metadata - Systems, methods, and computer program products for searching objects, metadata associated with the objects, and attributes assigned to or associated with the metadata. Referring to herein as metadata for the metadata, these attributes may be associated with one or more metadata field values of a metadata field name which, in turn, may be associated with an object being or already indexed in a search index of a search system. Each attribute may be optional, dynamically created, indexed, and searchable via the search index. There can be multiple attributes associated with the same metadata field value, each being represented as a key-value pair. This metadata for the metadata approach can be highly efficient. For example, the ability to search multiple attributes associated with the same metadata field can eliminate the potential need to create multiple metadata fields for the same value in different languages, countries, etc. | 07-17-2014 |

20100106842 | SYSTEM AND METHOD FOR PROVIDING TIMER AFFINITY THROUGH NOTIFICATIONS WITHIN A SESSION-BASED SERVER DEPLOYMENT - The session-based server deployment can be comprised of an engine tier that is designed for high throughput processing of communications and a state tier that maintains state information for access by the engine tier. The engine tier can include a plurality of engine nodes that process incoming messages. The state nodes can contain call state, including various timers. When processing a call, an engine can set various timers in the state tier. Upon expiration of a timer, the state node can transmit a notification assigning the timer to the corresponding engine node which handled previous communications for the call. This affinity between the timer and its respective engine can provide numerous benefits, such as reduced latency and more localized data access. | 04-29-2010 |

20120126439 | METHOD AND SYSTEM FOR GENERATING SULFUR SEEDS AND GRANULES - Sulfur (or sulphur) spray nozzles disposed with a cooling tank spray liquid molten sulfur into the cooling liquid in the tank. Solid sulfur seeds are formed in the cooling liquid and settle in the tank. The cooling tank may be a spiral dewaterer tank that has a screw conveyor at the bottom of the tank that moves the seeds to a granulating drum for enlargement into sulfur granules. The cooling tank may also be used to capture and remove sulfur dust from a slurry of sulfur dust and water recycled from the granulating drum. The sulfur dust in the cooling tank may be captured by contact with molten sulfur droplets streaming down the cooling liquid column such that the dust particles become incorporated into the droplet, thereby being converted to seed. The granulating drum may be equipped with two or more sets of segmented lifting flights. The sets of flights may not be in alignment. The flights may be spaced apart from the inside surface of the drum with segmented rib members. The rib members may allow for the movement of sulfur seeds and granules between the flights and the inside surface of the drum as the drum rotates. | 05-24-2012 |

20090242467 | System that removes contaminants from sulfur - A system for removing contaminant from sulfur to a level that allows re-processed sulfur to reenter a supply chain. The system melts contaminated sulfur, filters the molten sulfur, and then dispenses the less contaminated sulfur after filtering it. More specifically, solid contaminated sulfur enters a settling tank, while heated molten sulfur circulates through the system and the settling tank. The circulation of the molten sulfur assists in the melting process of the solid sulfur, allowing the solid sulfur to melt efficiently. In preferred embodiments of the system, the system uses steam jacked sulfur lines and steam tracing to maintain temperatures for melting the solid sulfur and maintaining the molten state of the sulfur circulating through the system. Furthermore, the system comprises a programmable logic controller, which controls motors, pumps, valves, and environment monitoring instruments. | 10-01-2009 |
