A quick-release clamping holder for a sewing needle, embroidery needle or the like has a needle receptacle (2) on which a needle clamping part (8) is preferably pivotally supported. A fixing element (14) is provided in order to clamp and fix the needle clamping part (8) in place, whereby said fixing element is pivotally or rotatably supported relative to a longitudinal central axis (13) of the needle and thus can be slid onto and off the needle clamping part (8). Actuation is simple and safe.

Fatty animal starting material is subjected to extraction using a gas at supercritical conditions. The extraction operation takes place in a static column without circulation. The gas used as a solvent in the extraction operation may be subsequently regenerated and re-used. Any innocuous gas may be used provided its critical constants fall within the pressure and temperature ranges dictated by the extraction material. The fats are completely extracted without chemical modification of either the extract or the residue, both of which retain their natural composition. The water content of the extracted fats is less than 0.2% by weight. Scrap fat from meat and offal, such as visceral fat, may be used as starting material.

A burner with a casing seal is used to create a combustion cavity at a temperature sufficient to reservoir sand. The burner creates and sustains hot combustion gases at a steady state for flowing into and permeating through a target zone. The casing seal isolates the combustion cavity from the cased wellbore and forms a sealed casing annulus between the cased wellbore and the burner. Water is injected into the target zone, above the combustion cavity, through the sealed casing annulus. The injected water permeates laterally and cools the reservoir adjacent the wellbore, and the wellbore from the heat of the hot combustion gases. The hot combustion gases and the water in the reservoir interact to form a drive front in a hydrocarbon reservoir.

In a method for improving the efficiency of a search engine in accessing, searching and retrieving information in the form of documents stored in document or content repositories, the search engine comprises an array of search nodes hosted on one or more servers. An index of the stored document is created. The search engine processes a user search query and returns a result set of query-matching documents. The index of the search engine is configured on the basis of one or more document properties and partitioned, replicated and distributed over the array of the search nodes. The search queries are processed on the basis of the distributed index. The method realizes a framework for distributing the index of a search engine across several hosts in a computer cluster, relying on three orthogonal mechanisms for index distribution, namely index partitioning, index replication, and assignment of replicas to hosts. In this manner, different ways of configuring the index of a search engine are obtained and provide a much improved resource usage and performance, combined with any desired level of fault tolerance.

High permeability channels or wormholes found in hydrocarbon reservoirs having hydrocarbon-bearing formations can be remediated by heating the formation with dry, hot flue gases, injecting produced water into the formation through an injection well, and forming steam within the formation and spaced away from the injection well. The steam can be created at a steam generation interface occurring between a dry, hot gaseous drive front and an injected water front. Managing a quality of the steam formed along the steam generation interface, by increasing the combustion gas flow rate or decreasing the rate of water injection, allows for the initiation of precipitation and controlled deposition of solids dissolved in the produced water.
