Abstract: The improved clutch of the present invention includes a fluid actuated piston in the pressure plate assembly which may selectively and gradually be moved into and out of position to engage and disengaege the clutch plate between the pressure plate assembly and the flywheel. The improved clutch also includes a fluid actuator circuit to control the selective and gradual engagement of the clutch assembly.

Abstract: An interchangeable nose-piece for releasable connection to a pair of sport sunglasses is shown.

The interchangeable nose-piece includes means for supporting a pair of prescription eyeglass lenses and connection means which substantially conform to the standard nose-piece for interchangeable use and releasable connection to the sport sunglass shield.

Abstract: A protective eyeshield (10) with detachable components is disclosed. The eyeshield consists of a detachable lens (11) maintained in a frame (12) by notches (46 and 48) on the lens which cooperate with brackets (50 and 51) on the frame and by insertion of the side edges (44) of the lens into slots (20) in the frame, The eyeshield is held in place on the head of the wearer by a strap (13) attached to a rotatable connector (14) attached to the frame, The connector's rotatability allows the position of the strap to be adjusted to the wearer. An optional eyeglass frame (15) having eyeglass lenses (68) mounted therein may be attached to the eyeshield frame to form a part of the eyeshield for simultaneous wearing of eyeglasses with the eyeshield.

Abstract: An apparatus for inserting and removing a sensor into and from a hot tap on a fluid conveying pipeline includes a pair of parallel threaded drive rods interconnecting a sensor plate and a mounting plate which are operatively connected to the sensor and the hot tap, respectively. The drive rods are interconnected by a sprocket and chain system which rotates the opposite drive rod in reaction to rotation of either drive rod. Load indicators are installed on the drive rods to assist the operator in correctly positioning and loading the sensor in the pressurized pipeline. The drive rods are connected to the sensor plate through moveable threaded sleeves which accommodate irregularities in the drive rod.
