Abstract: A detachable lamp assembly for temporary installation in the existing electrical socket at the rear of the first trailer in a dual-trailer truck coupled to a tractor cab. The lamp assembly is energized when the headlamps of the tractor are lighted, and illuminates the forward end of the second trailer for coupling and uncoupling the first and second trailer in the usual low-level light conditions at night in trucking yards. Thus utilized, the lamp assembly is a useful aid in preventing breakage or damage of the vulnerable air connectors, and other adjacent parts, which damage commonly occurs when the driver cannot visually monitor the coupling or uncoupling operation.

Abstract: Fittings for the recirculation system of a pool in which a Venturi T-fitting has an air inlet connector. Water entering the inlet end of the T-fitting advances through an adapter, which is in threaded engagement with a Venturi insert formed with a discharge orifice. The insert is formed with a nut-like projection. The water entering the adapter is discharged through the discharge orifice of the Venturi insert as it is mixed with air under pressure so as to be aerated. The aerated water is discharged from the Venturi T-fitting for passage through an inlet fitting for the recirculation of water in a pool. For regulating the size of the discharge orifice, the Venturi insert is removably replaced.

Abstract: A carpet trimmer comprising a base plate with slots directed at right angles to the working edge of the base plate. Underlying the base plate is a post holder with upstanding threaded posts protruding through the slots of the base plate. Overlying the base plate is a blade holder that engages the posts for movement with the post holder. Suitable nuts on the posts lock the post holder and the blade holder in an adjusted position relative to the base plate. A wall guide depends from the blade holder in spaced relation to the working edge of the base plate to define a passageway for a carpet edge to be trimmed by blades on the blade holder. When the nuts are loosened, the posts can be moved within the slots of the base plate toward or away from the working edge of the base plate. In so doing, the post holder and the blade holder move therewith. This action adjusts the distance between the working edge of the base plate and the wall guide to accommodate different thicknesses of carpets.

Abstract: An electrical magnetic switch adaptable for use in a digital wristwatch in which a command function for a digital wristwatch is controlled by a switch or an actuator. The magnetic switch is normally open and is closed by the movement of the wrist of the wearer to overcome the magnetic force from a permanent magnet on a magnetizable movable armature. The displacement of the magnetizable movable armature against the urgency of the magnetic force closes a circuit for performing a command function for the digital wristwatch. For regulating the magnitude of force on which the magnetizable movable armature is displaced against the urgency of the magnetic force of the permanent magnet, means are provided for adjustably positioning the permanent magnet relative to the path of travel of the magnetizabe movable armature. Alternatively, the movable armature may be a permanent magnet and the adjustably positioned means may be made of magnetizable material.

An hydraulic drive motor is connected to the conveyor of the conveyor-trailer to impart movement thereto under the control of the servo mechanism. When the servo mechanism is spaced from the wheel of the truck trailer, the conveyor of the conveyor-trailer is idle.

Abstract: A jet propulsion system for boats in which the thrust force center line is below the boat reaction center line to urge the propulsion system thrust line to tilt downwardly. The tilting of the propulsion system thrust line downwardly lifts the stern of the hull to create a suitable vertical vector. As a consequence thereof, the boat is urged into a planing position for the reduction of drag on the boat in the lower speed range. At the higher speeds, dynamic water pressure reacts on the intake to urge the tilting of the thrust force center line upwardly toward a horizontal position to reduce the depth of the bow of the boat submerged in water for reducing the drag on the boat. A tension spring controls the angle of the tilting of the thrust force center line to attain the changeover at a selected speed for optimum operation.
