  • Publication number: 20240125253
    Abstract: A valve actuation system comprises a first arm having a first arm contact surface and operatively connected to a valve actuation motion. A second arm having a second arm contact surface is operatively connected to the at least one engine valve. A discrete lost motion device is provided that is controllable between a first, motion conveying state and a second, motion absorbing state. The discrete lost motion devices comprises a plunger contact surface and a housing contact surface. The housing contact surface is configured to engage one of the first or second arm contact surfaces, and the plunger contact surface is configured to engage another of the first and the second arm contact surfaces. The first and second arm contact surfaces, the housing contact surface and the first plunger contact surface are configured to support the discrete lost motion device between the first arm and the second arm.

  • Publication number: 20240115259
    Abstract: An apparatus includes a first jaw (16) and a second jaw (618, 718, 900) that cooperate to clamp and staple tissue (90). The second jaw includes a jaw body (620, 720, 902) and a distal tip (619, 719, 906) pivotable relative to the jaw body between a first discrete and a second discrete position. First and second openings (663, 784, 785, 932, 934) are both defined by one of the distal tip or a structure (621, 920) located proximal to the distal tip. A projection (637, 781, 918) is defined by the other of the distal tip or the structure. The projection is positionable within the first opening (663, 785, 932) to releasably retain the distal tip in the first discrete position, and within the second opening (663, 784, 934) to releasably retain the distal tip in the second discrete position.

  • Patent number: 6981777
    Abstract: An emergency running light for vehicles such as watercraft includes a cup-shaped housing made of a transparent, thin flexible wall which defines a cup-shaped interior chamber. A liquid component of a two-component chemiluminescent compound and a breakable capsule containing a second component thereof are disposed within the interior chamber. The running light is activated to produce a predetermined color of light by squeezing the flexible housing to break the container. This causes the first and second component liquids to form the chemiluminescent compound and resulting light. The housing is attachable to a surface of the watercraft following activation using an adhesive ring which engages a flat rim of the housing.
