Certain non-limiting exemplary embodiments are disclosed which teach a method for playing a game comprising initiating a game play, displaying a first plurality of indicia arranged in a plurality of rows and a plurality of columns such that there are a plurality of paylines through a contiguous plurality of indicia, selecting a subset of the first plurality of indicia taken along one or more columns, displaying a second plurality of indicia which includes the selected subset of the first plurality of indicia, achieving an award at least as large as the largest award associated with the plurality of paylines. A payline can be selectively displayed to the user. Legal tender, a token, and a non-legal tender prize are non-limiting examples of the kinds of awards that may be awarded. The columns of indicia for the game are, for example, arranged as visually spinable reels. In certain embodiments a video display may be utilized to display the indicia.
摘要:
The present invention relates to an internal combustion engine having an injector which functions as a a positive displacement pump and dispenses an amount of lubricant fixed for each and every operation of the injector. The fluid dispensed could be a lubricant delivered directly to crankshaft bearings, camshaft bearings, tappets or cylinder sleeve. Alternatively the fluid could be fuel, water or urea delivered to an exhaust system upstream of a catalytic converter. The injector can have a one-way valve with a valve element having a domed or conical surface for directing fluid flow across a sharp edge which induces turbulence in the fluid flow.

A percutaneous stented valve delivery device including an inner shaft, a sheath, and a delivery capsule. The sheath slidably receives the inner shaft. A capsule proximal zone is attached to the sheath. A capsule distal zone is configured to transition between normal and flared states. A diameter of the distal zone is greater in the flared state, and the capsule includes a shape memory component that naturally assumes the normal state. The device is operable to perform a reversible partial deployment procedure in which a portion of the prosthesis is exposed distal the capsule and allowed to radially expand. Subsequently, with distal advancement of the capsule, the distal zone transitions to the flared state and imparts a collapsing force onto the prosthesis, causing the prosthesis to radially collapse and become recaptured within the delivery capsule. The capsule can include a laser cut tube encapsulated by a polymer.

A valve operating mechanism for an internal combustion engine includes a drive member that engages a control arm at a contact point spaced apart from the pivot axis of the control arm, and a control member that operates to vary the contact point in order to vary a spacing between the contact point and the pivot axis of the control arm to vary the amplitude of reciprocation of a cam surface of the control arm and to vary the portion of the cam surface which is engaged by a cam follower member during pivoting of the control arm to thereby vary the amount of lift and/or opening duration of the engine valve.
摘要:
Component fabrication and in particular fabrication by deposition processes for large components is made more convenient by initially depositing a masking deposition layer 2 upon a thin substrate 1 such that subsequently shaped metal deposition techniques can be used. Previously, the relatively thin nature of the substrate 1 has rendered the hot heat plume 11 of the shaped metal deposition technique too intrusive. It will be understood that this heat plume 11 may distort the thin substrate 1. By initial application of a protective masking deposition layer 2, the underlying substrate is protected by that layer 2 from the heat plume 11 generated by the shaped metal deposition process.

With reference to FIG. 1, the present invention provides an internal combustion engine (10) comprisinga variable volume combustion chamber (13); an air intake system (18,20,21) for delivering charge air to the combustion chamber (13); an exhaust system (17) for relaying combusted gas from the combustion chamber (13) to atmosphere; and a fuel injection system (19, 21, 22, 23, 24, 25, 26) for delivering fuel into the charge air for combustion therewith in the combustion chamber (13). The fuel injection system (19,21,22,23,24,25,26) comprises a fuel injector (19) which functions as a positive displacement pump and dispenses an amount of fuel which is fixed for each and every operation of the injector (19); and a controller (23) which controls the operation of the fuel injector (19). In response to an increasing engine speed and/or load the controller (23) increases in amount the fuel delivered per engine cycle by increasing in number the occasions the fuel injector (19) is operated per engine cycle. In response to a decreasing engine speed and/or load the controller (23) reduces in amount the fuel delivered per engine cycle by reducing in number the occasions the fuel injector (19) is operated per engine cycle.
摘要:
A bioresorbable endoluminal prosthesis for placement in a body lumen having a stent substrate of a first metallic material that has a lower electrical potential than a standard reference electrode. The stent substrate is coated with a biodegradable polymer having a second metallic material dispersed therein, wherein the second metallic material has a higher electrical potential than the standard reference electrode. After implantation of the stent within the body lumen, the second metallic material is present in the polymeric coating in a sufficient concentration to cause galvanic corrosion of the first metallic material such that over time the stent substrate is bioresorbed.

A system for replacing a pulmonary valve includes a conduit having a lumen, a delivery catheter and a replacement valve device disposed on the delivery catheter. The replacement valve device includes a prosthetic valve connected to a valve support region of an expandable support structure. The valve support region includes a plurality of protective struts disposed between a first stent region and a second stent region. A method for replacing a pulmonary valve includes implanting a conduit and delivering a replacement valve device to the conduit. The replacement valve device includes a valve connected to a valve support region that includes a plurality of protective struts. The method also includes deploying the prosthetic valve device from a delivery catheter into the lumen, positioning the prosthetic valve device within the conduit lumen and expanding the prosthetic valve device into contact with the inner wall of the conduit.
