  • Patent number: 4802067
    Abstract: A headlamp aiming and leveling device is provided for attachment to an automotive headlamp to facilitate leveling and aiming of the headlamp beam relative to an automotive vehicle upon which the headlamp is installed. The device comprises: a level-indicating device including a housing. At least one, first part of the housing is affixed to a given surface of a headlamp, such that a remaining portion of the housing is movable relative to said affixed part for varying the inclination of the housing in such a fashion as to permit adjustment of the level-indicating device to indicate a level condition. An adjusting arrangement is operatively coupled with the housing at a second part thereof spaced from the part thereof affixed to the headlamp for moving the housing for achieving the level indication while the headlamp is held in a condition wherein the headlamp beam is level. A locking arrangement is provided for locking the adjusting arrangement in the position at which the level condition is indicated.

  • Patent number: 4735203
    Abstract: A retractable, non-reusable bleeding time lancet apparatus comprises a housing having an end opening, a blade, and a carrier for fixedly mounting the blade and mounted in the housing for sliding motion toward and away from the end opening. A resilient biasing member is mounted in the housing in a prestressed condition and is operatively coupled for selectively urging the carrier for achieving sliding motion toward and away from the housing end opening. A non-resettable release member normally retains the biasing member in its prestressed condition and is selectively activatable for releasing the resilient biasing member to urge the carrier in a sliding motion for projecting at least a cutting edge of the blade through the end opening. Cooperating surfaces on the housing and carrier define respective limits of sliding motion of the carrier corresponding to extended and retracted positions of the blade cutting edge relative to the housing end opening.
