  • Patent number: 6743097
    Abstract: A gaming device, such as a slot machine, determines a balance and a “dispensed amount” that is less than the balance. The dispensed amount may be determined by, for example, receiving signals from one or more key presses that specify the dispensed amount. Alternatively, the dispensed amount may be determined in accordance with one or more “balance management rules”. The gaming device in turn dispenses the dispensed amount, for example, by dispensing an amount of currency, transferring the dispensed amount to an account or adjusting a balance of a remote gaming device. The balance is adjusted by the dispensed amount, and this adjusted balance is available for initiating a subsequent play of the gaming device.

  • Patent number: 6743110
    Abstract: A golf course is laid out for play in a front round and a back round, with each round being played on a sequence of eleven holes spaced apart along a course that traverses natural rough environs. The holes are integrated into the existing natural rough environs thereby forming playable green areas adjoining out-of-play rough areas. Each hole includes a green located within an out-of-play boundary line, and the distance between the approximate center of the green and its out-of-play boundary line is fractionally proportional to the spacing distance that separates the green in play from the preceding green. All play is single stroke from green-to-green (hole-to-hole). The spacing distance from one green playing area to the next is limited to a predetermined distance that is calculated to allow it to be spanned in a single stroke by a beginning player.

    Abstract: A movable lever for a transmission chain, which is able to pivot smoothly, and avoid seizing on its supporting shaft, comprises a unitary, molded resin lever body composed of a chain-engaging shoe and a plate-receiving portion, and a reinforcing plate in a slot in the plate-receiving portion. The plate and the plate-receiving portion have coaxial, cofastening mounting holes which receive the mounting shaft. Reinforcing ribs are provided on a side of the plate-receiving portion and their ends are notched to provide grooves which promote the flow of oil, which accumulates on the lever, toward the mounting holes so that adequate lubrication of the mounting hole in the plate is achieved.

  • Patent number: 6743131
    Abstract: A tensioning device for a drive system having a flexible drive element mounted on at least one driven member, the tensioning device including a first tensioning member having a first side, a second side, and a first contact surface for contacting the drive element and a second tensioning member having a first side, a second side, and a second contact surface for contacting the drive element. The tensioning members are secured to the first and second ends of an elongated connecting member, positioning the members in a spaced relationship to one another so that the contact surfaces of the tensioning members are in opposing disposition facing one another. The tensioning members are spaced apart so as to permit the first and second runs of the drive element to pass between the tensioning member contact surfaces.

  • Patent number: 6743132
    Abstract: The invention is an improved tensioner for tensioning a power transmission belt. The tensioner is of the type having a track, a carrier mounted in sliding relation with the track with two degrees freedom of movement, a pulley rotatably mounted upon the carrier and for engaging the power transmission belt, a spring biasing the carrier in longitudinal relation to the track, and a damping mechanism that modifies the biasing of the spring based upon movement of the carrier in relation to the track. It is improved by the damping mechanism having a shoe placed in asymmetrical damping relation to the carrier and the track. Further, the shoe includes a first friction bearing surface in mating relationship with a second friction bearing surface of the track.

  • Patent number: 6743133
    Abstract: The present invention relates to a chain drive, in particular camshaft/camshaft drive for an automotive engine, the chain drive comprising at least two chain gears and a drive chain. Such a chain drive shall be made more compact without excessively great losses in its low-noise characteristics. To this end at least two chain gears are arranged in laterally offset relationship with one another in axial direction. The drive chain is a multiple-track chain. Each of the offset chain gears has assigned thereto a separate track of the multiple-track chain due to the lateral offset. The tip diameters of the offset chain gears are overlapping.

  • Patent number: 6743134
    Abstract: In a silent chain, wear of the connecting pins and bushings, and wear elongation of the chain itself, are suppressed by the formation of through holes in the approximate centers of the teeth of toothed link elements for relieving strains in the inner peripheries of the bushings due to press-fitting of the bushings into the toothed link elements. The shortest distances between the bushing hole on the one hand, and the through-hole, the outside tooth surface and the inside tooth surface, on the other hand, are made substantially equal to one another. The through holes also reduce the weights of the individual link elements and contribute to a reduction in overall weight of the chain.

  • Patent number: 6743135
    Abstract: A procedure to assemble a vehicular transmission from modular components. One determines the type of transmission to be assembled within a prefabricated housing sub-assembly, and then selects a central shaft sub-assembly from a family of modular shaft assemblies. A modular shaft sub-assembly appropriate to the transmission to be assembled is selected and then operatively connected to the housing sub-assembly to provide a housing assembly. An input sub-assembly is selected and operatively connected to the housing assembly. An output sub-assembly is selected from a family of modular output sub-assemblies, the selected output sub-assembly to be appropriate to the transmission to be assembled. The selected output subassembly is operatively connected to the housing assembly to provide a transmission of the type desired.

  • Patent number: 6743136
    Abstract: A differential assembly for a motor vehicle comprises a differential case rotatably supported in an axle housing and forming an inner cavity housing a differential gear mechanism. The differential gear mechanism includes at least one pinion mate gear rotatably supported by a pinion shaft extending through radial bores in the differential case. The pinion mate gear has a back face adapted to cooperate with a complementary pinion seat surface through a thrust washer disposed therebetween. The differential case further includes at least one lubrication passage formed within the differential case adjacent to the radial bore receiving the pinion shaft. The lubrication passage provides fluid communication path for the lubricating oil from an oil reservoir in an axle housing to a space between the pinion seat surface of the differential case and the thrust washer of the pinion mate gear.

  • Patent number: 6743137
    Abstract: An eccentric gear for providing a speed difference between two machine elements which are rotatably journalled in relation to a reference member and individually rotatable around a symmetry axis. The gear includes two pairs of co-operating gear rims, one of which in each pair is eccentric in relation to the axis and one of which is in the form of a male gear rim with out-turned teeth, and the other one is a female gear rim with in-turned teeth. One of the gear rims in each pair is rigidly connected to a homologous gear rim in the other pair of gear rims and situated along a common axis that is eccentric and oblique in relation to the axis while the other gear rims are rotatable in relation to each other.
