Abstract: A system includes a gas turbine having a turbine shaft disposed along a rotational axis, a turbine casing disposed circumferentially about the turbine shaft, a combustion gas path disposed between the turbine shaft and the turbine casing, and a turbine stage disposed in the combustion gas path. The turbine stage includes a plurality of turbine vanes disposed upstream from a plurality of turbine blades. The gas turbine includes an isothermal expansion system coupled to the turbine stage, wherein the isothermal expansion system includes a plurality of flame stabilizers configured to vary axial positions of combustion within a turbine stage expansion of the turbine stage to reduce temperature variations over the turbine stage expansion. The flame stabilizers are disposed in different axial positions over an axial length between leading and trailing edges of the turbine blades, wherein at least one flame stabilizer is coupled to each of the turbine blades.

Abstract: A game system operates by: receiving character attribute selection data to be associated with a game character, wherein the character attribute selection data indicates a unique subset of a set of character attributes of a character attribute database; generating, based on the character attribute selection data, display data associated with the game character; facilitating, based on the display data associated with the game character, generation of a player token NFT associated with the game character; and preventing use of the unique subset of character attributes of the character attribute database in generating other game characters. Facilitating play of a game when the player token NFT is validated.

Abstract: A programmable cardiac tissue stimulator having a receiving coil and RF pulse width check/data separator (6) for receiving programming data, a communications State sequencer (8) for directing the sequence of command activities within the apparatus, command decode and address latch (12), memory (16, 18, 20, 22, 30, 40, 42) for storing the received programming data, pulse generator logic (24) for generating an output stimulation pulse according to a programmed stimulation scheme, a first timer (32), a second timer (34) and third timer (44) interactive with the pulse generator (24) and memory (16, 18, 20, 22, 30, 40, 42) for carrying out the timing functions of the pulse generator logic (24), a first sensor (46) for sensing electrical activity in the atrium, a second sensor (48) for sensing electrical activity in the ventricle, antitachycardia logic (50) for limiting the rate of natural stimulation of cardiac tissue, an output lead (54) to the atrium, an output lead (56) to the ventricle, and a control clock (28

Abstract: Alkaline silicates such as sodium metasilicate are prepared by a method that prevents unreacted batch ingredients to come in contact with furnace walls. The method also prevents any molten material from contacting the floor of the furnace. The raw materials and unreacted melt are confined to the central portion of the furnace by maintaining vigorous bubbling around the periphery of the melting furnace. The vigorous bubbling action prevents migration of unreacted raw material to the furnace walls. The bubbling eminates from means that extend up from the furnace floor and therefore, the portion of the material in the lower part of the furnace bed is in the solid state.
