Abstract: An expandable baton includes a plurality of sections adapted to be stowed in a nested, collapsed position. The sections may be opened by swinging the baton in a whipping action into a locked extended position. Each of these sections may be made of similar or dissimilar materials, with the tip section having at least a portion being made of a relatively high mass material to preserve strike force when used in a whipping motion and the largest, handle section being made of a lightweight material to reduce weight of the overall baton. Intermediate sections may be included and may be made of either the lightweight material or the heavy mass material, as desired, taking into consideration force requirements in combination with overall balance and weight objectives.

Abstract: An on-line fishing depth indicator is adapted to be placed either in series or in parallel on a typical fishing line in combination with fishing bait. The indicator is adapted to read and store the maximum depth of the bait during a trolling operation under controlled conditions. This permits the user to determine the performance of the bait under certain, predefined conditions. The electronics and pressure transducers associated with the indicator are self-contained in the unit.

Abstract: An expandable baton is constructed of heat treatable alloy steel and is formed according to a method which provides both ease of workability of the component materials and strength for the resultant baton. The disclosed method comprises the steps of first forming the sections from heat treatable alloy steel, then annealing the baton components to soften them, then forming the components into the desired shapes, and finally hardening the components. The resulting baton provides the strength and reliability required in such a device.

Abstract: An anti-motion sickness mechanism comprises a platform suspended from a conveyance for movement about all principal axes. Any vertical movement of from 0 to 0.5 Hz has a tendency to cause motion sickness. A supplementary vertical movement of about 2.5 Hz is added to the platform to break up such vertical movement into sub-movements having a reduced tendency to cause motion sickness.

Abstract: A marine carburetor is provided with an adjustment screw mounted on the throttle lever that is engageable with the cam follower in such a manner that movement of the adjustment screw urges the cam follower into engagement with the surface of the throttle cam, at which point continued movement of the screw results in movement of the throttle lever so that the throttle plate may be adjusted to an idle position.

Abstract: A marine drive for a boat (3) includes a longitudianlly extending propeller shaft (17, 37, 38) which effectively carries the propeller hub (18, 41, 42) between a pair of fore and aft conical surfaces (26-29; 44-47; 51-54) which mate with similar conical surfaces associated with the hub. These mating surfaces prevent orbiting movement of the propeller. The mating surfaces also center the hub on its axis and provide for high torque retention. The construction is such that water is kept out of the joint between the hub and propeller shaft, with pre-applied lubricant being retained therein. The inventive concepts may be utilized with a single propeller system (FIG. 2), or dual propeller installation (FIG. 4).
