摘要:
Process of coating magnesium alloys to improve the corrosion resistance and adhesive bonding strengths of the alloys. The process comprises treating the magnesium alloys with an acidic aqueous solution comprising, per liter of solution, from about 0.01 to 10 grams of a water soluble trivalent chromium compound, about 0.01 to 10 grams of hexafluorozirconate, about 0.0 to 5.0 grams of at least one hexafluorosilicate and/or a tetrafluoroborate, from about 0.0 to 5.0 grams of at least one water soluble divalent zinc compound and from 0.0 to 10 grams of a water soluble thickener and/or 0.0 to 10 grams of a water soluble surfactant.

The system includes an efficient, closed irrigation system in conjunction with insulating components for minimizing the harmful effects of extreme changes in ambient temperature, moisture and chemical concentrations in plant containers. Mechanisms are provided for permitting a single pallet, or a single plant within a pallet, to be readily removed from an integrated plurality of pallets without interfering with irrigation of the plants that are contained in the remaining pallets.

Pretreated aluminum and aluminum alloys and the process for pretreating said aluminum substrates to improve its corrosion-resistance, and adhesion properties which comprises pretreating said aluminums with an effective amount of an acidic aqueous solution having a pH ranging from about 2.5 to 4.5 and comprises effective amounts of a trivalent chromium compound, alkali metal hexafluorozirconates, at least one alkali metal fluoro-compound, and small but effective amounts of water soluble thickeners and/or surfactants.
摘要:
A method and system for managing a Bingo game while allowing a repeat player to play the same sets of numbers in multiple sessions of Bingo. The player preselects numbers which he wishes to play in multiple Bingo sessions. The hall stores the numbers in the memory of the computer. On the date of the Bingo game, the player chooses which preselected Bingo numbers to play. The player is provided with a ticket having the preselected numbers with a control number for each set of numbers and a validation number for the ticket. The player is also provided with a receipt indicating the number of preselected sets of numbers bought by the player and the validation number for the ticket. When a player calls Bingo, the hall enters the control number of the potentially winning set of numbers into the computer to verify the set of numbers is a winner.
摘要:
A method is described for synchronously rendering digitized media streams. Each digitized media stream is made up of a sequence of media samples having media-specified timing. The described method includes calculating presentation times for media samples of different media streams based in part on the media-specified timing of the media samples and also based in part upon the desired synchronization of the different media streams relative to each other. The calculated presentation times indicate when the media samples should be rendered relative to a common clock reference. The method further includes attaching a media sample's calculated presentation time to the media sample, and then routing the media sample to a sink component for rendering. The sink component renders the respective media samples of the digitized media streams at the approximate presentation times of the samples relative to the common clock reference.

The fertilizing apparatus comprises a diffusion member having a porous member associated with it to retain fertilizer inside a compartment defined by the diffusion member. The diffusion member provides a diffusion pathway that is protected from gravitational water flow and rapid temperature fluctuation. The compartment is filled with fertilizer and inserted into growth media adjacent a plant's root system so that the diffusion pathway is substantially occupied by the plant growth media. A plurality of diffusion members, each member having a different length, may be used to establish diffusion times for specific fertilizer formulations. The fertilizing apparatus can be adapted for use with a closed, insulated pallet system for producing container-grown plants.
摘要:
A combination Bingo and Poker game is described. The game uses a game board (10) containing a matrix of Bingo places (16). The Bingo places each have a Bingo number (26) and playing card indicia (28). The game is played similarly to standard Bingo with the players marking the places on the game board as the numbers are selected by the host entity (12A). A player has a winning BINGO when the marked places form a winning Bingo configuration. The playing card indicia of the places of the winning Bingo configuration are then used to form a potentially winning Poker hand.

A method and system (10) for storing preselected Bingo numbers which allows a player to play the same sets of Bingo numbers (56) in multiple sessions of Bingo. The player preselects Bingo numbers to play in multiple Bingo sessions. The numbers are stored in the memory (16) of the computer (12). The player selects which preselected Bingo numbers to play for a specific session of Bingo. A ticket is provided having the selected sets of Bingo numbers with a control number (58) for each selected set of numbers and a validation number (60) for the ticket.
摘要:
An aqueous composition for post-treating metal coated substrates such as cadmium-plated steel or zinc-nickel coated substrates and the process for using said composition to improve the corrosion-resistance, abrasion, and adhesion bonding properties of the metal coatings. The composition comprising an acidic aqueous solution having a pH ranging from about 2.5 to 4.5 containing effective amounts of trivalent chromium salts, an alkali metal hexafluorozirconate, at least one alkali metal fluoro-compound, and effective amounts of water soluble thickeners and/or surfactants.
摘要:
Composition for post-treating anodized aluminum and aluminum alloys and the process for using said composition to improve the corrosion-resistance, abrasion, and adhesion bonding properties of the anodized aluminum and its alloys. The composition comprises an acidic aqueous solution having a pH ranging from about 2.5 to 4.5 containing effective amounts of trivalent chromium salts, alkali metal hexafluorozirconates, an alkali metal fluoro-compound e.g. fluoroborates and/or fluorosilicates, and effective amounts of water soluble thickeners and surfactants.
