A portable power system for a hand tool employs a high-voltage transmission of power from a battery pack over a cord to a DC to DC converter, which steps the transmission voltage down to rated tool voltage. The system uses a switching transistor to transmit power according to a duty cycle which varies automatically according to tool current draw and voltage. The DC to DC converter employs synchronous rectification with an inductor-capacitor network to transform a duty cycle square wave into DC power. The startup voltage sense feature permits powering up the converter circuitry only when needed. The converter will shut down if no current has been drawn by the tool for a predetermined period of time or if the converter unit is in danger of overheating, as determined by a stored algorithm. The portable power system has safeguards to prevent fouling or shorting in wet environments, is adaptable to left or right handed users, and is physically configurable into a variety of carrying modes.

A paper cutter assembly having an extruded rail assembly including a base and a rail formed at right angles to each other. A carriage assembly is mounted on the rail for translational movement across the rail. End blocks are provided in each end of the rail assembly for pivotally connecting the rail assembly to guide blocks for pivotal movement between operative and inoperative positions with respect to the paper.

A tiller handle is provided for use with one or more push-pull cables innerconnected to the shift and the throttle mechanisms of an outboard marine engine to control the shift and the throttle operations of the engine. The tiller handle includes a rotatable cam member with one or more cam tracks located on its outer surface. Each push-pull cable is maintained within a distinct cam track such that rotating the rotatable cam member actuates the push-pull cables thereby controlling the operation of the shift and the throttle mechanisms of the engine.

The invention is directed to storage containers and lids for storage containers which provide for a secure closure and a storage container which is airtight and leakproof. The lid includes a generally U-shaped closure made of a plastic material for securing to a container base; a center window also made of a plastic material and preferably the same as the U-shaped closure; and a thermoplastic material which provides for a sealing gasket on the underside of the U-shaped closure for mating with the container base and a perimeter seal on the outside of the U-shaped closure and around the outer circumference of the center window. The lid may further include a gripping tab made at least in part of thermoplastic material in the lid corner for opening or closing the container, and wings made of a thermoplastic material in one or more portions or corners of the lid.

An outboard marine motor housing by a cowl assembly having an upper cowl section and a lower cowl section includes various features for improving the structural integrity of the cowl assembly and for providing a water-resistant seal at the joint between the cowl sections and at various points of entry of cables and other mechanical devices. A rotary latch mechanism includes an internal hook connected to a shaft leading to an external rotatable handle. The shaft is supported on either side of the point of engagement of the hook to the shaft. In particular, a bearing is formed integrally with the bottom of the lower cowl section and is adapted to receive an end of the shaft for support thereof. The catch for the latch mechanism is provided with a hook-receiving member having support on both sides of the point of engagement of the hook-receiving member by the hook. In pair of depending arms connected to an upper plate, which is adapted for direct connection to a pair of columnar lugs formed integrally with an end of the upper cowl section.

A connector for attaching a central core wire (11) of a flexible cable to a control element (13) has a cable guide (15) attached to the core wire (11). A pivot pin (22) extending through a bore in the cable guide (15) is attached to the control element (13) and has an annular groove (23) in one end. A locking body (24) has a cylindrical section (25) reciprocally mounted on the cable guide (15) and an arm (27) extending forward to engage the groove (23) in the pivot pin (22). A notch (29) at the end of the arm (27) snaps around the pivot pin (22) to hold it in place.
