  • Publication number: 20050111298
    Abstract: An eductor mixing device (10) has a main body or housing (28) of a generally cylindrical shape and an inner tube (42) for one component to be mixed with a liquid is mounted in main body (28) with a vortex chamber (56) formed in an annulus between the main body (28) and the inlet flow tube (42). Pressurized liquid enters the vortex chamber through a generally rectangular entrance opening (36) along an arcuate surface (42) which smoothly merges with the cylindrical surface (30) of the main body or housing (28). A liquid in a swirling motion moves in a descending helical path about inner tube (42) and passes through a gap G between coaxial frusto-conical surfaces (55) and (68) of the converging inner nozzle (52) of the inner tube (42) and an outer coaxial liquid nozzle (60) of diffuser ring (58).

  • Patent number: 5851011
    Abstract: The present invention relates generally to a casino-type method of playing poker and to computer implementations thereof, wherein one or more players play a single hand against the house. It relates more particularly to a multi-deck method of playing a poker-like game wherein multiple players progressively wager on a single five-card player hand which is matched against a later-dealt best-five-of-seven card dealer hand, the winning hand being determined by traditional rules of poker. The instant invention allows multiple players to win based on the card combinations in the single player hand. It also provides for the possibility of a bust hand and for the purchase of insurance to protect against same. Finally, the instant invention is suitable for use with one or more progressive jackpots which a player may become eligible to win by paying a premium.

  • Patent number: 4854120
    Abstract: The present invention relates to a device for extending the performance life of a gas turbine engine by rotating the turbine after shutdown to achieve uniform cooling. The apparatus includes a motor, a high ratio gearset engaged with the motor, an overridable coupling means engaging the gearset with an accessory shaft of the turbine, and a logic circuit. The circuit determines when the engine has been shut down and continues to rotate the turbine for a predetermined period of time. If an external force interferes with the post-shutdown turning, the circuit will sense that force and compensate for it.

  • Patent number: 4460427
    Abstract: Process for the preparation of flexible circuits formed from flexible photohardenable elements having at least one organic elastomeric polymeric binder which comprises(a) exposing imagewise said element,(b) applying particulate conductive metal, e.g., nickel, copper, to the unexposed image areas, optionally(c) heating the metal bearing areas, then(d) removing excess metal particles, optionally(e) fixing the particulate metal to the layer by heating, exposing to UV light or mechanical embedding, and(f) plating electrolessly or soldering the metal containing areas. The process can be operated continuously to prepare single and double layer flexible printed circuits, membrane switches, etc.

  • Patent number: 4360570
    Abstract: Electrically conductive through-holes in a substrate are prepared by (a) laminating a film based plastic photosensitive toner-receptive stratum to at least one surface of the substrate; (b) applying a pressure differential across the stratum covering the substrate holes, the outside pressure exceeding that inside the holes; in either order (c) removing at least one film base or (d) exposing the photosensitive stratum imagewise, (e) adhering metal or catalytic particles to hole walls and image areas, (f) optionally hardening or curing the particulate areas and (g) providing an electrically conductive printed circuit and through-holes, e.g., by plating metal electrolessly, soldering or conjoining the metallized or catalyzed areas.
