Abstract: An automatic fishing apparatus is disclosed which comprises a reel means mounted on a free clutch plate of a clutch assembly. A second clutch plate of the clutch assembly is provided on a driven shaft which also passes through the first plate. Two members are provided with bevelled surfaces one of the members having a rod which is moved when a fish takes a line coupled with the rod. Movement of the rod causes rotational movement of one of the members and also lateral movement of one of the members, which lateral movement is transmitted to the free clutch plate to force the free clutch plate against the driven clutch plate so that drive is transmitted to the free clutch plate and the reel means to reel in the line. Once the fish is reeled in the fish contacts the rod which causes the rod to move to return the said one of the members to its original position to separate the clutch plates to thereby stop the rotation of the reel means.

Abstract: A fishing device is provided which in a single structure can be used to perform a plurality of fishing operations, such as a motorized jigging operation, a casting operation, a trolling operation and a motorized jigging trolling operation. The device imparts a lifelike swimming action and oscillatory movement to lures, to baits and to live or plastic minnows. This imparted action and movement is caused by an electric motor in the handle which revolves an eccentric striker arm to deflect a length of line positioned in the path of the striker arm. Two separate control means permit the device to impart such movements to lures and baits of differing weights, sizes, buoyancies and physical structures. The first control is a variable rheostat which varies the angular velocity of the striker arm and thus varies the rate at which the striker arm contacts the length of fishing line positioned in the path of the striker arm.

Abstract: A robot doll with an internal drive unit for automatically causing the doll in prone face-down position to bend at the waist until reaching a semi-erect position, then to straighten-up to a standing position, and then to wobble from side-to-side, or to simulate walking, and/or to fall down. A first switch actuates the doll to move from prone position to standing. A reversing switch, actuated as the doll stands, reverses the drive motor to complete standing action. A rod is reciprocated in and out of at least one foot to simulate walking actions and to cause the doll to tip. An interior frame carrying an electric motor and gears is loosely mounted and a cam mounted thereon causes the frame, hence the doll, to wobble while in the standing position. The doll eventually falls from standing position and impacts its pivoted arms on the support surface. This opens a reversing switch and starts the series of moves over again.

Abstract: The disclosure concerns a pumping apparatus for working fluid, in a hydrodynamic coupling, or the like. Working fluid is stored in a sump and is to be lifted by a spinning disc to an elevated container from which the working fluid is then directed back into the spinning disc. The periphery of the spinning disc picks up the working fluid from the sump and carries it around to spary it up toward a deflector at the top of the housing which deflects the fluid into the container. A groove-like duct encloses the lower quarter of the disc for directing the fluid back toward the surface of the disc. The disc has a trapezoidal cross-section peripheral groove for further carrying the fluid beyond the top exit of the duct so that the fluid may be thrown toward the deflector at the top of the housing.

Abstract: A free-piston Stirling engine usable as a heat pump has a closed vessel filled with helium working gas which is heated at the bottom end and cooled at the top end. The vessel contains a displacer supported for axial reciprocal oscillation on a gas spring post mounted on the vessel. The displacer shuttles the working gas from end to end in the vessel, alternately heating and cooling the gas. The vessel is sealed with a flexible diaphragm which flexes in response to the pressure wave generated in the vessel as the working gas is alternately heated and cooled. When the diaphragm flexes, it displaces hydraulic fluid in a hydraulic chamber and drives a power piston for driving a linear alternator and a gas compressor. A gas spring operating on a second hydraulic cylinder on the other side of the power piston stores part of the energy of the piston stroke and returns it for the return stroke.

A second control valve may be further provided within the exhaust gas recirculation passage so as to close the exhaust gas recirculation passage when the load applied to the engine is above a predetermined value.
