Title: A method for production of porous semiproducts from aluminum alloy powders
Inventor: LITVINTSEV ALEXANDER IVANOVICH
IPC: C22C1/08
Filed: 2002-06-11
Abstract: The invention relates to powder metallurgy and can be used for producing porous materials having high thermal and sound insulation and energy absorption combined with light mass, incombustibility and the ecological cleanness thereof. According to said invention, during mixing a powder of an aluminium alloy with porophores, the powders of aluminium oxide and aluminium hydroxide ranging from 1 to 10 % and crushed particles of secondary aluminium alloys of the dimensions ranging from 0.5 to 4.5 mm are added to the powder mixture. The particles are mixed in an atrittor until a mechanically alloyed powder alloy is obtained. The powder mixture being heated, it is poured in a vertical container which vibrocompacts the mixture and maintains the temperature thereof. Afterwards, said mixture is transferred to the rectangular groove of a rolling mill in order to carry out a continuous hot compaction in a dead groove of horizontal rollers at a temperature ranging from 430 to 500 °C according to the following condition: H = h x .gamma. x .alpha., where H is an opening between rollers along the arc of contact in mm, h is the thickness of the produced sheet, .gamma. is a compaction ratio of the powder, .alpha. is an experimental ratio equal to 1.5>=.alpha.>=4.5. Said invention reduces production cost by using aluminium alloy refuses, expanding the range of sheets and plates and increases the efficiency of the production thereof.

Patent CA-2460237-A1 (CA)
Inventor: ENDRES HOLGER
IPC: C08F290/06
Filed: 2002-09-06
Abstract: The invention relates to a method for producing thin, hydrolysis-resistant, scratch-resistant and antisoiling coatings on metals or plastic surfaces, whereby the coating agents can be directly applied to the cleaned metal surface and are subsequently cross-linked by high-energy radiation, particularly UV radiation. The substrates can be coated in the form of tape before being manipulated into their desired outer shape. Substrates coated in this manner are no longer susceptible to soiling caused by foodstuffs, cleaning agents or fingerprints and can also be rendered antibacterial.  Objects coated in this manner are thus suited for use in the field of architecture, in the interior work of buildings, in furniture manufacturing, for jewelry applications, and particularly in the household, in sanitation, in the hospital sector and in the food-processing and pharmaceutical industries.

Title: A method of playing a casino card game involving wagering
Inventor: MCBRIDE SCOTT
IPC: G06F19/00
Filed: 2004-03-12
Abstract: A method of playing a card game, wherein each player places an ante wager in an ante wagering area on a casino table. After all players at the table have placed their ante in their respective ante wagering area, a dealer then deals three cards face up, and sequentially places one card in each of 3 card areas on the table in front of the dealer that are designated as, "Dealer Hand 1", Dealer Hand 2" and "Dealer Hand 3". Players then bet, based on the first card drawn to the dealer hands, in order to correctly guess which of the 3 dealer hands will later be the best Blackjack hand when all 3 of these dealer hands have been played, by traditional Blackjack rules, with each players wager correspondingly being placed in the player's betting option areas, designated as "Hand 1", "Hand 2" and "Hand 3".Once the dealer has played out each of the dealer's three hands, the players which have placed a bet or wager on the dealer hand determined to be the best Blackjack hand will have a winning wager by which, in accordance with standard Blackjack rules, is the best hand is the hand closest to 21 without going over 21 (busting). In successive rounds, each of the dealer hands are reset by removing one or more cards therefrom, until the dealer hands each total 16 or less, whereby the game again resumes, with players betting again on the dealer hands shown to correctly guess which of the 3 dealer hands will later be the best Blackjack hand when all 3 of these dealer hands have been played.

Abstract: After the start of operation of an engine (1), the characteristic change of a humidity sensor (19) is detected on the basis of the transition characterist ic of output date from the humidity sensor (19) with respect to integrated wate r quantity data indicating the integrated water quantity fed to an HC adsorben t (7) through exhaust gases. Further, the data concerning the characteristics of the individual humidity sensors (19) are held by the resistance values of resistor elements (21) installed in the connectors or the like of the humidi ty sensors (19). Parameters for grasping the state of the HC adsorbent (7) are corrected according to the detected characteristic change of the humidity sensor (19) and the characteristics of the other individual humidity sensors (19), and the state of the HC adsorbent is grasped on the basis of the corrected parameters. This compensates the influence of the characteristic change of the humidity sensor and the influence of variation of the characteristic of each individual humidity sensor, thereby properly monitori ng the state of degradation or the like of the hydrocarbon adsorbent (HC adsorbent).

Abstract: L'invention concerne des pigments anticorrosion à base de cobalt, qui contiennent un complexe stabilisateur de valence/cobalt trivalent ou tétravalent. Un matériau inorganique ou organique est utilisé pour stabiliser l'ion cobalt trivalent ou tétravalent et former un composé modérément soluble dans l'eau. Des stabilisateurs spécifiques permettent de réguler le degré de libération du cobalt trivalent ou tétravalent durant l'exposition à l'eau et d'adapter la compatibilité de la poudre lorsqu'il s'agit de pigment utilisé dans un système liant donné. Les stabilisateurs peuvent également modifier les caractéristiques de traitement et de manipulation des poudres constituées. Les combinaisons stabilisatrices de cobalt/valence sont déterminées en fonction des principes bien établis de la chimie des combinaisons du cobalt. Aux fins de l'invention, on présente de nombreuses combinaisons stabilisatrices de cobalt/valence capables d'égaler les performances des systèmes classiques au chrome hexavalent.
