A63F 1300

US Classification:

463 23, 463 29, 463 42

Abstract:

Systems and methods are provided to facilitate games of skill for prizes played via a communication network. According to one embodiment, a potential game to be played at a remote player device via a communication network is determined. The potential game is evaluated to estimate an amount of player skill required to play the potential game, the evaluation being performed based on a sample of player performance information. The potential game is also evaluated to determine an ability of an automated game playing device to play the potential game. The potential game is modified if (i) the amount of player skill required is unacceptable or (ii) the ability of the automated game playing device is unacceptable.

International Classification:

D21C 700

US Classification:

162239

Abstract:

An oxygen delignification method and apparatus in which a charge of heated wood pulp is reacted with oxygen in the presence of a charge of caustic soda in a plurality of reaction stages located between mixing stages in which caustic is mixed with the wood pulp. The use of the plurality of mixing stages reduces peak pH exposure of the wood pulp that would otherwise occur if the charges of caustic and wood pulp were mixed all at once. Moreover, the caustic mixed in such manner replenishes neutralized caustic and ensures that the average pH level is increased above that in conventional oxygen delignification. The increase in average pH level favors an increase in the delignification. Filtrate from a washing stage is introduced into the mixing stages to prevent wood pulp degradation. Oxygen is mixed within the wood pulp by a wood pulp mixer that employs coaxial perforate passageways between which the wood pulp is retained and driven but which allow the oxygen to pass in an inward radial direction of the passageways to mix with the wood pulp.

International Classification:

D21C 1104

US Classification:

162 3011

Abstract:

A method of producing oxidized white liquor from white liquor in which sodium sulfide is oxidized to sodium sulfate. In accordance with the method, an oxygen containing gas is contacted with the white liquor at a temperature of at least 110. degree. C. and such that the total pressure of oxygen and water vapor is no less than 9. 2 atmospheres during the contacting.

International Classification:

F28B 900

US Classification:

62172

Abstract:

A refrigeration device in which a heat load is refrigerated within a refrigeration chamber. Refrigerant is supplied, preferably, from a supply of turboexpanded air employing a compressor to compress the air and a turboexpander to expand the compressed air to a low temperature. A venturi-like device such as an ejector circulates the refrigerant within a circulation path within the refrigeration chamber so that heat is transferred from the heat load to the refrigerant. An incoming mass flow rate of the refrigerant is delivered to a high pressure inlet of the venturi-like device and a recirculation mass flow rate of the refrigerant is received within the low pressure inlet from the circulation path after the refrigerant has heat transferred thereto. A high pressure outlet discharges a mixture of the refrigerant that comprises the incoming and recirculation mass flow rates to the circulation path and prior to the heat load. Controls are provided to either control the recirculation mass flow rate of the refrigerant or a by-pass flow of refrigerant in a by-pass line communicating between the high pressure inlet and outlet.

International Classification:

C04B 3700

US Classification:

264 61

Abstract:

A method for heat processing of multilayered ceramic articles containing internal conductive metal patterns that have been formed from multiple ceramic green sheets individually coated with inks or pastes containing conductor metal/metal oxide material, and thereafter assembled in registry with each other and laminated. The heat treating method to convert the laminate to the final ceramic article includes a first heating stage under conditions to promote burn-out of the organic polymeric binder present, a second stage performed under conditions to reduce the metallic conductor, and a third stage to sinter the multilayered composite to form the final ceramic article. The invention is characterized by the presence of moisture in an amount of from about 0. 5% to about 3% of the gaseous atmosphere in at least the sintering stage, and preferably at both the binder burnout stage and the sintering stage. Multilayered articles heat treated under these conditions exhibit a combination of improved properties, including little or no staining in combination with improved conductivity and dielectric properties.

International Classification:

D21C 1104

US Classification:

162 29

Abstract:

A method for producing bleached wood pulp in which wood chips are digested in polysulfide liquor to produce brown stock pulp. The brown stock pulp is washed to produce washed brown stock wood pulp and weak black liquor and the washed wood pulp is then delignified in an oxygen delignification stage to produce oxygen delignified wood pulp. The delignified wood pulp is then ozone bleached in an ozone bleaching stage in which a waste stream principally containing ozone, carbon dioxide and oxygen is produced. The ozone-bleached pulp is introduced into an extractive oxidation stage which can include peroxide to further bleach the pulp and the product of the extractive oxidation stage is then either introduced into either a peroxide or chlorine dioxide bleaching stage. The waste stream is recovered and scrubbed with either white liquor, oxidized white liquor, or fully oxidized white liquor either in a separate scrubber or during oxidation reactions occurring in either polysulfide, white liquor or complete white liquor production stages. The scrubbing with white liquor or oxidized white liquor removes ozone and carbon dioxide so that the scrubbed stream can be utilized in the oxygen delignification stage.

US Classification:

427102

Abstract:

The present invention provides an improved method for firing thick film inks in hybrid circuits which comprises firing different copper compatible thick film materials in a single firing atmosphere. The method comprises the steps of providing a paste suitable for application to a ceramic substrate, applying the paste to the substrate by a conventional technique such as screen printing, drying the substrate, and firing the substrate at an elevated temperature in an ambient comprising an inert gas and carbon dioxide to form the electrical component. In another embodiment, the substrate is fired in an ambient comprising only carbon dioxide.

US Classification:

162 3011

Abstract:

White liquor produced from black liquor is partially or completed oxidized. The white liquor contains dregs that are utilized as a carbon based catalyst. Dregs are produced by separating the dregs from green liquor an intermediate product between the black liquor and the oxidized white liquor. After formation of the oxidized white liquor, the dregs are separated therefrom to form a waste dreg stream which can be recycled so that part of the dregs present within the dregs containing white liquor stream to be oxidized is contributed by the waste dreg stream.
