Abstract: A rescue clamp rescues precariously located victims, such as swimmers in water, such as seas, rivers, streams, ponds or swimming pools, climbers in deep ravines, persons on top of a burning building or persons fallen down a well. The rescue clamp includes an orifice clamp into which a victim inserts the hand and forearm. A trigger is activated by being in spring loaded physical contact with a user's forearm or is activated when a trigger handle is grabbed by the victim's hand, to cause the clamp to snugly engage and grip around the victim's wrist or forearm. The rescue clamp grips the wrist or forearm by off-centered hour glass shaped jaws that rotate in unison to reduce the size of the orifice therebetween.

The rescue clamp includes an orifice clamp into which a victim inserts the hand and forearm. A handle trigger is grabbed by the victim's hand, to cause the clamp to snugly engage and grip around the victim's wrist or forearm. The rescue clamp grips the wrist or forearm by off-centered hour glass shaped jaws that rotate in unison to reduce the size of the orifice therebetween. To facilitate rotation, there is an eccentric off-center cam motion of the clamping jaws contributing to a grasping action in general. The clamping jaws automatically tighten around a victim's wrist or forearm.

Abstract: A simple speed controller for small direct current motors having a hollow body with a joystick extending out from the body. Within the housing the two facing side walls have nonconductive substrates with conductive traces. Transistors are connected to both substrates and the joystick has conductors to act as wipers for potentiometers which act to control the speed of the motor.

Abstract: A maritime sail furling mechanism furls a sail around a rotating luff extrusion from an open to a furled position in a natural fashion while functioning under load. A novel bearing assembly, including upper and lower bearing portions, accommodates static and horizontal loads, and rotates with both the luff extrusion and the sail cable wire. The sail boat mainsail furling and unfurling device includes a rotatable cable with the luff extrusion, around which extrusion the mainsail is wound while the sailboat is under motor power. Each upper and lower bearing portion includes several cylindrical hollow members, one middle member of these members freely rotates as a collar about a circular array of tapered roller bearings placed with their tip ends at a center of a sunburst pattern cage. The tapered roller bearings rotate axially, but their spherical heads, located away from the center of the array, rotate about the circumferential collar.

Abstract: A liquid-operated reciprocating prime mover assembly includes upper and lower reservoirs formed of interlocking cylinders enabling relative expansion and contraction of the interior volumes thereof, and a shuttle valve disposed intermediately and connectingly between the upper and lower reservoirs for receiving a stream of operating liquid and directing the same alternatingly between the reservoirs. As the liquid is directed to each reservoir that reservoir is caused to expand, carrying the shuttle valve in a first direction along a rectilinear path, while when fed to the other reservoir the liquid causes the valve to be correspondingly carried in the opposite direction along the path. A body washing apparatus incorporating the prime mover assembly further includes an operatively rotatable brush assembly carried along the rectilinear path and supporting a brush rotatable as the shuttle valve traverses the path for cleansing contact with a user's body.
