Granted: 2008-09-02
Abstract: An apparatus and methods for preventing the accumulation of unwanted materials in an enlarged inner diameter portion (160) of a casing or housing (110). In one aspect of the invention, a sleeve (150) is disposed in the housing to isolate an annular area (155) defined by the outer surface sleeve and the wall of the enlarged inner diameter portion. The sleeve prevents unwanted materials from being disposed in the annular area. The sleeve can later be expanded into the enlarged inner diameter portion, removed from the wellbore or destroyed.  In another aspect of the invention, the sleeve is provided and disposed to cover the enlarged inner diameter portion. By covering the enlarged inner diameter portion, unwanted material is prevented from accumulating at said portion and from interfering with the expansion of the next casing into said portion to form a monobore. The sleeve can be made from materials that are dissolvable, elastically deformable, or retrievable.

Abstract: An apparatus for reducing foam in a liquid storage tank, includes a bottomless elongated housing adapted for use in a substantially horizontal orientation. The housing has an interior peripheral defining wall forming an interior cavity, an inlet at a first end, and an outlet at a second end. A plurality of baffles are positioned at spaced intervals along the interior cavity of the housing. The baffles include upper baffles extending downwardly from the wall leaving a flow space below and lower baffles extending upwardly from the wall leaving a flow space above. The upper baffles and the lower baffles alternate, thereby defining a serpentine flow path between the inlet and the outlet.

Abstract: The present invention: provides a steel pipe pole base and a method for reinforcing the steel pipe pole base that do not allow the strength to lower in the vicinity of the weld toe of a rib even in the event of applying repeated bending moment; and is characterized by forming peening processed portions 20 by ultrasonic vibration at the weld toes 16 of tabular ribs 12 welded to the base of a steel pipe pole 10 in the form of a T-joint or the weld toes of inverted-U shaped ribs 13 or inverted-v shaped ribs 14, the ribs being bent at the upper end portions, welded to the base of a steel pipe pole 10 in the form of a T-joint. Preferable treatment conditions are 20 to 50 µm in amplitude and 10 to 50 kHz in frequency. In particular, the present invention makes it possible to remarkably improve the fatigue property because stress concentration is relayed by the synergetic effect of bending the upper end portions 16 of the ribs 13 and applying a peening treatment.

Dès qu'une condition de conclusion (112) intervient par rapport à un rouleau (102), celui-ci (102) est désactivé. En l'absence de condition de conclusion, le processeur active de nouveau le rouleau (104, 106). La machine à sous continue à activer les rouleaux jusqu'à la désactivation de la totalité des rouleaux. Le joueur reçoit alors le gain total accumulé (108) correspondant au jeu à bonus.

Granted: 2008-07-08
Abstract: A well logging tool apparatus is disclosed for conducting measurements in a borehole environment surrounding a borehole that traverses a subsurface formation. The apparatus includes an elongated conductive mandrel having a longitudinal axis, an antenna array positioned about the mandrel and including a transmitter for transmitting electromagnetic energy into the formation, and a sleeve positioned about the antenna array. The sleeve has an outer surface positioned for exposure to the borehole environment and an inner surface positioned radially inward of the outer surface. The apparatus further includes a first set of electrodes and a second set of electrodes. Each electrode has an outer end and an inner end positioned radially inward of the outer end, and is supported on the sleeve such that the outer end is exposed on the outer surface of the sleeve for conductive contact with an adjacent conductive borehole environment. Further, the first and second sets of electrodes are spaced longitudinally apart such that the transmitter is positioned longitudinally therebetween (e.g., the first set is positioned above the transmitter while the second set is positioned below the transmitter). Importantly, electrodes of the first and second sets are conductively interconnected with the mandrel such that when the well logging apparatus is operated in a borehole environment having borehole currents therein, one or more current path loops are provided for shorting borehole currents. The current path loops include a first conductive path between the conductive borehole environment, one of the first set of electrodes and the mandrel, and a second conductive path between the conductive borehole environment, an electrode of the second set of electrodes, and the mandrel.

Abstract: Security can be provided for lottery tickets having data printed thereon in a bar code or other machine readable media by covering only a portion of the bar code with a scratch-off material. Removing the scratch-off material, or in some cases only a portion of the scratch-off material, can permit machine validation of the lottery tickets. For bar codes having a specified level of redundancy, it is desirable to cover at least enough of the bar code to prevent the machine reading of ticket validation data encoded in the bar code.  Also, a lotter ticket can include a bar code printed on the ticket having both inventory and validation data along with a bar code printed on the front of the ticket including the validation data. All or part of the bar code printed on the front of the ticket can be covered by a scratch-off material.  Also, the validation and redemption process can be expedited by having a player ticket checker read a ticket identifier printed on the lottery ticket so that this information can be checked and automatically entered in an agent terminal.
