Abstract: Claimed is a trolling device for use on a moving boat. The trolling device utilizes a continuous looped guide groove, which spirals around a driveshaft, and has a connecting loop that joins the first spiral with a second spiral that then travels back down the driveshaft to a second connecting loop. As the driveshaft continuously rotates in one direction, a travel pin with an attached fishing lure moves back and forth along the driveshaft. One or more speed change zones are incorporated into the driveshaft as regions of changed pitch in the spiral guide grove. The speed change zones result in the speed of the lure changing as it passes through the water, so that the lure will have an occasional burst of speed, and then slow down during its travel through the water.

Abstract: The invention relates to a safe mechanism for resistance to drilling, by use of a door mounted crankshaft mechanism. The crankshaft includes a shoulder which transfers force to the safe door rather than transmitting it to other lock mechanism components. A crank plate attached to the crankshaft rotates from an open position to a locking position, and by rotation moves a link arm with attached locking pins laterally into engagement with the doorframe. A re-locker device locks both the crank plate and the link arm in place to make entry more difficult.

Abstract: A decoy for attracting waterfowl having an upper body portion, a non-parallely oriented keel and an anchor. The decoy body is non-parallely connected to a keel by an attachment means. This attachment means may be fixed or adjustable. This non-parallel orientation between the keel and the upper body allows the decoy to maintain a desired orientation within a body of water when acted upon by a wind or water current. An anchor connected to the combination of the decoy and the keel provides a means for maintaining the decoy in a generally fixed location. This combination of features allows the orientation of a group of decoys to be varied so as to provide a desired natural looking presentation.

Abstract: A temporary boat latch for use on a surface having spaced boards. The latch having a rod connecting a first crossbar having a length greater than the distance between the spaced boards and a width less than the distance between the spaced boards to an attachment device. A slideable connection sleeve, which has a generally perpendicularly connected second crossbar configured to fit over the spaced boards. In use, the first crossbar is inserted between the spaced boards and is oriented so that the crossbar cannot be withdrawn from between the boards by pulling the device upward. The sleeve is then lowered into the space between the boards so that a portion of the sliding means attaches to the boards and prevents the securing device from falling through the space between the boards.

Abstract: A roller wall guard system for use on a surface-finishing machine having a circular guard ring of a given circumference made up of a pair of wall guards. Each wall guard has an arc shaped arm having a first end attached to a roller and extending along a length to a second end also having a roller. Each arm is pivotally connected to the surface-finishing machine at an intermediate location between the first and second ends, so that the arm pivots within a controlled arc. The length of the arms and the diameters of the rollers are configured to define a line between a point of rolling engagement of the first roller against a second surface and a point of rolling engagement of the second roller against the second surface. The line lies outside of the circumference of the guard ring.

Abstract: A downhole control tool (20) comprises a first sleeve (22) defining a first profile (28), a second sleeve (24) axially and rotatably movable relative to the first sleeve (22) and defining a second profile (30) for selectively engaging the first profile (28), and a third sleeve (26) axially movable relative to the first sleeve (22) and defining a third profile (36) for selectively engaging the second profile (30). The profiles are engaged and disengaged by axial reciprocal movement of the third sleeve (26). The profiles are arranged such that on the second profile (30) engaging the first profile (28) and the second profile (30) engaging the third profile (36), the second sleeve (24) is rotated relative to the first sleeve (22). Thus, the tool (20) provides an arrangement which converts a reciprocal movement into a rotary movement.

Abstract: A bus driver signaling device wherein a user is able to push a button to activate a light source signal at a bus stop. Pushing the button creates a light signal able to be viewed by the bus driver, thereby signaling the bus driver that a passenger is awaiting the bus driver at the bus stop.

Abstract: A device for obtaining electric power from moving water, made up of a floating cylindrical body having a first end extending to a second end along a cylindrical surface having at least two blades. Each end of the floating cylindrical body is fixedly connected to a waterwheel sprocket, and rotatably connected to an arm pivotally connected to an anchor. The waterwheel sprockets are connected to a generator sprocket by a drive means. When the new device is placed and held in a body of moving water, the moving water impacts against the blades and causes the floating cylindrical body to rotate. The rotation of the floating cylindrical body causes the first and second waterwheel sprockets to rotate and move the drive means which are connected to a generator and in turn create electricity.
