Abstract: A method and system for a card-based game with simulates a traditional keno game through the use of a specially designed deck of playing cards. The system includes a computer, a scanner, a specialty card shoe, and the specially designed deck of cards. The method includes first shuffling the deck of cards by the specialty card shoe. Next, a card is drawn from the deck of cards and scanned, thus extracting a unique number that is associated with a spot on a traditional Keno card. The unique number is then associated and indicated to a spot on a simulated Keno card by the computer. This process is repeated for twenty iteration to compile winning numbers. The winning numbers are then compared against guessed spots associated with a user account to identify a set of matching spots. A primary payout transaction is managed based on the set of matching spots.

Abstract: Compressed gas is used to reciprocate pistons arranged around a nutation frame which is driven cyclically by the piston to provide a rotary output to drive a motor shaft. The cylinders have tapering walls to assist thermal flow to the gas to prevent condensation. Where the gas expansion takes place in stages, different cylinders may be dimensioned to operate under different stages of expansion of the gas.

Abstract: A tape cassette which has a limited access rewind system includes a one-way coupling arranged to communicate between the spool and the rewind mechanism. The one-way coupling mechanism includes an engagement disc which is mounted in the housing and forms a part of the take-up spool. The one-way coupling device serves to engage automatically to prevent rotation of the spool relative to the engagement member in the unwinding direction and to release automatically to permit free rotation of the spool in the winding direction. A locking mechanism is located in the housing which is operable to secure the engagement member against rotation and thereby prevent rotation of the spool in the take-up direction. The locking mechanism may be released to disengage the engaging member to permit free rotation of the engagement member and spool about the take-up access. The tape cassette also includes a releasable latching mechanism which serves to lock each spool against rotation during shipping and handling.

Abstract: A nutation frame is mounted on a base at a fulcrum connection for limited angular movement about those axes which are perpendicular to a nutation axis and is restricted against cumulative rotary movement about the nutation axis. The nutation frame rigidly connects reciprocating connections on axes approximately parallel to the nutation axes and radially spaced therefrom and a member designed for circular motion about said axis being axially displaced from said fulcrum. The frame can thus convert circular movement about the nutation axis to reciprocating movement or vice versa.

Abstract: A cage-type wafer carrier is provided which can be loaded and unloaded with semiconductor wafers by means of an automatic wafer transfer machine. No large slots are required in the bottom section of the cage-type carrier for allowing elevator lifts to pass therethrough to engage the wafers.

Abstract: A quartz wafer boat or carrier includes three slotted parallel members, each member including a plurality of grooves aligned with corresponding slots in the other members, for carrying semiconductor wavers in precise spaced parallel relationship to each other. The bottom member is located in substantially offset relationship to the center of gravity of the supported wafers. A first side member is located in substantial offset relationship to the opposite side of the center of gravity, so that the bottom member and the first side member completely support the wafers. A third side member is located on the same side of the center of gravity of the wafers as the bottom member, but normally does not support the wafers, but retains them if the wafer boat is accidentally tilted. The slots in the second side member are deep enough to prevent the edges of the supported wafers from contacting the bottoms of those slots as a result of thermal expansion of the supported wafers, to avoid binding and stressing thereof.

Abstract: The invention is a burner for combustible gases such as a propane/air burner. It is concerned with an improvement to the flame stabilizer in such a burner. The flame stabilizer is unique in that it forms the gas flow into two similar paths and, then, reunites the paths so that they interface and form a vortex sheet at their interface that, in turn, forms a vortex downstream of the stabilizer. The vortex sheet formation protects the stabilizer from the heat of the burned gases and provides very efficient stabilization for the flame.

Abstract: The invention is a machine for receiving a tape cassette, the tape of which has been wound on the take up reel of the cassette. The cassette has a clutch that must be released before the tape can be rewound.

Abstract: A tape cassette having a body and two reels rotatable with respect to the body, one of the reels having a roller clutch between it and the body, the roller clutch having rollers, a ring extending around the rollers, and a roller cage, the rollers being contained in channels with a ramp surface formed in the roller cage, the rollers having a wedging surface adapted to wedge between the ramp surface and a ring to prevent rotation of the reel in one direction but permit rotation in the other direction, the rollers being adjustable to remove them from operative relation with the ring whereby to free the reel for rotation in either direction.

Abstract: Axial flow impeller having at least two rows, preferably three rows, of a plurality of blades secured substantially radially to a rotor for rotation in a plane about the axis of the rotor. The blades have the same pitch throughout their lengths with the blades of the first row having a pitch angle less than the stall angle of the blades, preferably about 22.degree., the blades of the second row having a pitch angle greater than the pitch angle of the blades of the first row and less than the stall angle of the blades, preferably about 13.degree. greater than the pitch angle of the first row of blades, and the blades of a third row of blades having a pitch angle greater than the pitch angle of the blades of the second row and less than the stall angle of the blades, preferably about 13.degree. greater than the pitch angle of the second row of blades.

Abstract: This invention relates to a propane type gas burner that can be operated safely in an inverted position for an extended period of time and that has a reservoir of a glycol water type mixture to supply heat to vaporize liquified gas as it flows to the torch for burning.
