Title: Method for calculating a compression rate for a file to obtain a target file size by interpolating between data for two compressed reference files.
Inventor: GWAK JIN-PYO
IPC: H03M7/28
Filed: 2008-09-26
Abstract: Disclosed is a method for calculating the compression rate for a file so that a target file size can be obtained. The method start with obtaining data on the sizes of two reference files when compressed by a plurality of rates. One of the rates used is an initial rate, which is used to compress the target file. The difference between the size of the target file when compressed at the initial rate and the two reference files when compressed at the initial rate, with the required compressed size of the target file is used to determine the compression rate to be used. The initial compression rate and the reference files may be selected based on the type of data files to be compressed, the types including image files and audio files. File sizes for the two reference files are calculated based on the differences between the target file and the reference files when compressed at the initial rate. The target compression rate is the rate corresponding to the sizes of the calculated file sizes of the two reference files.

Title: Database migration or synchronization with ordering of data replication instructions based upon dependencies between data to prevent errors
Inventor: HOWARD GARY
IPC: G06F17/30
Filed: 2009-12-22
Abstract: Replication, such as migration or synchronization, of data, particularly held in databases, between a source (110) and target (120). A Replication entity model (800) is provided which includes replication entities which associate data elements in source (110) and data elements in a target (120). Directed relationships, or dependencies, between data in the source are also defined, for example with a directed relationship model (700, 705), such as a dependency graph or a directed acyclic graph. A replication engine (430) is adapted to instruct a transformation engine (420) to replicate each replication entity in turn. The order of these instructions is based upon the data dependencies in the directed relationship model. Each instruction may be performed only after confirmation that any predecessor replication entities upon which the present instruction data depends have completed correctly. Converting between different source and target data formats as part of the replication may also be provided.

Title: Improvements in or relating to insecticidal compositions
Filed: 1938-04-04
Abstract: 513,328. Insecticides; terpene ethers. HERCULES POWDER CO. April 4, 1938, No. 10260. Convention date, April 28, 1937. [Class 81(i)] [Also in Group IV] The effectiveness of insecticidal compositions containing a contact insecticide is increased by addition of a terpene ether. The contact insecticide may be pyrethrum or an extract thereof, derris, rotenon, nicotine or a compound thereof, an aliphatic thiocyanate, or a viscous petroleum hydrocarbon, and may be used in the form of a solution or suspension in kerosene for spraying, an aqueous emulsion for horticultural purposes, or as a dusting powder containing a diluent such as talc, bentonite or fuller's earth, or one of which the bulk is formed of powdered pyrethrum flowers, derris root or cubÚ. Pyrethrum extracts may be made with a terpene ether or a mixture thereof with another extraction agent and be diluted for use. Emulsions may contain petroleum oleate soap or sulphonated oil and may be prepared in the form of concentrates, without water, to be emulsified with water for use. The terpene ethers may be prepared by etherification of the hydroxyl group of a terpene alcohol with another alcohol, or by direct addition of an alcohol to a double bond of an unsaturated terpene compound. The alcohol used as etherifying agent in either method may be monohydric, such as methyl, ethyl, propyl, butyl, amyl, the monoethyl or monobutyl ethers of ethylene glycol, or the monoethyl ether of diethylene glycol, or may be polyhydric, such as ethylene glycol, diethylene glycol or glycerol. Examples of terpene alcohols to be etherified are alpha terpineol, borneol, fenchyl alcohol and crude terpene cuts rich in terpene alcohols. Unsaturated terpenes to receive an addition of an alcohol at a double bond are alpha pinene, nopinene, dipentene, terpinene, terpinolene, phellandrene, sylvestrene, alpha terpineol, beta terpineol, carene, camphene, bornylene, or crude mixtures containing those compounds, such as turpentine or pine oil, or crude fractions of these mixtures. Direct addition of an alcohol to the double bond of an unsaturated terpene may be carried out by treating the terpene with an alcohol at a temperature between 30‹C. and 200‹C., desirably in the presence of a catalyst such as p. toluene sulphonic acid, plenol sulphonic acid, benzene sulphonic acid, ethyl sulphonic acid, or abietyl sulphonic acid, the alcohol being used in excess of molecular proportions. The catalyst may be used in the proportion of 0.1 to 25 per cent. of the amount of alcohol used. The Specification as open to inspection under Sect. 91 refers also to the use of the compositions in the form of paints or gums having as a basis a natural or residual asphalt, and to compositions consisting only of a terpene ether dissolved or suspended in an inert solvent such as kerosene. This subject matter does not appear in the Specification as accepted.
