Abstract: A small, hand held, pocket size blackjack primer provides recommended actions for a blackjack player, depending upon the cards dealt to the player and the single open or face up card of the dealer. The device comprises an inner cylinder with a table of recommended actions therearound, and an outer cylinder with a single elongate window therein providing a view of a single row of recommended actions on the table at one time. A knob is provided at each end of the cylinder, to turn the table to an appropriate position. A position for the dealer's face up card and various combinations of the player's cards is provided adjacent the window. The player need only note the dealer's face up card and turn one of the knobs to position that value beneath the dealer card portion of the window, and then read the appropriate recommended action ((hit, stand, double down, or split a pair) beneath his or her card value appearing in the window. Additional features may be provided for convenience, such as color coordination of the appropriate recommended actions on the table and in the legend on the outer cylinder, a convex lens in the window to magnify the table, a flat base to prevent rolling of the cylindrical device, and/ or a keychain at one end thereof. The device is not a computer, as no numbers are manipulated, but serves as a primer or aid to the player for the optimum action at any point in the game.

Abstract: The present relates to an aquarium drainage assembly comprising a pipe member having an inner nipple adapted to be mounted within a designated opening formed in a wall of the aquarium and an outer nipple extending outside the aquarium. The inner nipple is permanently mounted within the aquarium by means of a locking means mounted on the pipe member, the locking means being adapted to tightly clamp the assembly to the wall. A sealing element is located on the pipe member and placed around the opening adjacent to an inner and an outer surface of the wall; it permits a watertight sealing of the assembly within the opening. A valve element mounted within the outer nipple allows to regulate water circulation through the assembly.  The locking means comprises a nut with a thread which is tightened around the inner nipple by means of a corresponding thread formed around an outer surface of the inner nipple and a stopper located on the outer nipple. The assembly tightly clamps to the wall by tightening the nut thus causing the wall to be clamped between the nut and the stopper means.

Title: High pressure filling nozzle
Inventor: DUBINSKY VICTOR
IPC: F16L37/12
Filed: 1998-05-22
Abstract: A fluid nozzle (1) for dispensing high pressure fluids includes an outer sleeve, a nozzle inlet (3) for receiving a high pressure fluid and a nozzle outlet (4) for discharging the high pressure fluid, an inner pipe in fluid communication with the nozzle inlet and the nozzle outlet, a valve biased to close the fluid flow passage through the inner pipe, a piston (6), and a plurality of radially movable connecting jaws (5) positioned about the periphery of the outlet (4).

Title: Air filter device and an automobile having the same
Inventor: LEE JEONG-KI
IPC: B60H3/06
Filed: 1996-12-26
Abstract: An air filter device and an automobile having the same includes an air filter bent without disassembling a cowl to be simply and easily replaced within a narrow space, and the air filter is commonly utilized to both left-handed drive type and right-handed drive type automobiles. For this, an air filter member is formed witha creasing part throughout the overall portion thereof. A  pair of frame members support the marginal edge of the air filter member, and a connecting frame member is integrally connected to the ends of the first frame member and second frame member to allow for bidirectional bending of the air filter member. Thus, the air filter is simply replaced without causing an interference with a frame mounted with a shock absorber. Also, the second frame member is upwardly bent at any time even though the up and down portions are reversed to have compatibility capable of being commonly employed into the left-handed drive type automobile and right-handed drive type automobile.

Inventor: VAN DER VEEN PETER H
IPC: G06F9/50
Filed: 1998-08-26
Abstract: The present invention relates generally to networks of computer systems, and more specifically, to a method and system of distributed operating system over a network of computer systems. Existing distrbuted operating systems have performance limits due to multiple layers, distinctions between client and server abilities, and inflexible architectures. The invention presents a system and method of distributed operating system with a single level architecture which is just as easily applied to a flexible network environment, including an internet communication link, as to a stand- alone computer. This is done by use of a message passing operating system, and by sending off-node messages to network managers which are capable of directing and receiving the off-node messages.

Abstract: A system and method for resolving ambiguity in an ambiguous position solution for a user terminal position in a satellite communications system which includes a user terminal (106), at least one satellite (104), and a gateway (102) communicating with the user terminal (106) through the satellite (104).  Each satellite (104) has a plurality of satellite beams (601-616) which each illuminate a region on the Earth in a known pattern relative to a satellite sub-track (404). A satellite beam (601-616) illuminating the user terminal (106) is identified along with its corresponding position relative to the sub-track (404). The orientations of possible user terminal positions (408A, 408B) and the identified beam (601-616) relative to the satellite sub-track (404) are compared to each other. Possible user terminal positions (408A, 408B) falling on an incorrect side of the sub-track (404) from the detected beam (601-616) illuminating the user terminal (106), are considered as incorrect solutions for that user terminal (106). The ambiguity solution can be determined using satellite identification and comparison elements in the user terminal (106), or at the gateway (102), in which case certain beam information is reported to the gateway (102). In further aspects of the invention, the beam being identified can be either a forward link (601-616) or reverse link (621-636) beam, or both, and each link has a different beam pattern.
