Abstract: Improved compositions have been developed which are selectively sequestered in acidic areas of tumors. When the compositions contain a radioisotope effective to report the presence of the composition, the compositions are useful for detecting tumors. When the compositions contain radioisotopes effective to kill cells, the compositions are useful for treating tumors. Methods for detecting and treating tumors with such compositions are also disclosed.

Abstract: A wind driven power generator has a rotational shroud assembly for maximizing wind input and a turbine assembly with a shaft that rotates within the shroud assembly. The shaft end extends through the base of the shroud assembly. The turbine assembly has elongate arms attached to the top portion of the shaft of the turbine assembly. Each arm is essentially perpendicular to the shaft and has a vertical wind blade attached to each of the arm ends and spaced equidistance apart around the shaft of the turbine assembly. The shroud assembly covers approximately half of the turbine assembly during rotation and maintains a windward direction for maximum wind on the blade fronts while shielding the back sides of the blades from the incoming wind.

Abstract: A steering connecting device for a boat couples the steering of a primary propulsion device and an auxiliary propulsion device. The primary propulsion device has an outer surface and is attached to the transom of the boat and an auxiliary propulsion device. There is a hinge assembly hingeably attached to and essentially parallel to the transom of the boat. There is a mounting plate fixedly attached to the hinge assembly. A tie rod is rotatably attached at a first end to the outer surface of the primary propulsion device and rotatably attached at a second end to the mounting plate. The auxiliary propulsion device is rigidly attached to the mounting plate. As the primary propulsion device is rotated from left to right during steering of the boat, the mounting plate also rotates from left to right thereby rotating the auxiliary propulsion device in unison with the primary propulsion device.

Abstract: A folding knife has a slot disposed in the thickness of the tang with a roller cam extending outside of the perimeter of the tang and rotatably attached within the slot. A safety assembly disposed within the handle has a stud extending through a slot in the handle and moves the assembly between a safe and an unsafe position. In the safe position the safety assembly is forced against the tang thereby preventing opening. An adjustable bias element assists the blade in exiting the blade slot. The bias element is in spring communication with the roller cam. Applying pressure to the stud urges the blade from the closed position as the bias element is centered with the roller cam and the blade is forced to an open position by the spring force of the bias element on the roller cam.

Abstract: A knife maintenance apparatus has a substantially rectangular hone body, a length with an open end and a base end, a width, a top surface covered with an abrasive material, and a bottom surface. There is a first hone edge extending along the length of the hone body and has a first radius. The opposite edge has a second radius and is parallel to and approximately the length of the first hone edge. The first hone edge and the second hone edge are approximately the hone body width apart. There is also a rectangular base portion that has a base top surface, a base bottom surface, a base width approximate the width of the hone body. The base portion has a sliding portion adjacent to and parallel to the base top surface. The base portion is hingably attached to the hone body along the base end and has at least one adjustment hole disposed through both the base portion and the sliding portion. There is at least one adjustment pin that extends through the adjustment hole.

Abstract: The handle of a folding knife has an integral spring biased portion that is biased toward the blade disposed in the center of the handle. The spring biased portion locks the blade in the open position by sliding under the rear of the blade when the knife blade is rotated to the fully open position. This same spring biased portion also locks the blade in the closed position by engaging in a recess in the side of the tang of the blade when the blade is rotated to the closed position. Preferably, the spring biased portion also employs a replaceable wear pin that makes all contact with the blade when rotating between the open and closed positions thereby eliminating the wear on the spring biased portion of the handle which is typically made from a soft, biasable material such as aluminum, zinc, or plastic.

On an opposite, second side there is a frame retention tab for attaching the queen bee rearing system into a standard wood hive box frame disposed along its length. The base portion also has at least one cage latch. There is a cage portion that has one open end and one enclosed end. The open end has at least one cage latch aperture. When a queen cell cup containing a queen bee cell is inserted into the cell insertion hole of the base portion, the open end of the cage portion is slid over the queen cell cup and firmly snapped into place around the base portion by sliding the cage latch of the base portion into the cage latch aperture of the cage portion.

Abstract: An extendable stirrup has a main stirrup and a retractable step parallel to and slideably attached to the main stirrup. The retractable step has an upper lift portion and a lower step portion. A latch holds the retractable step in the retracted position for riding. For mounting, the user releases the latch thereby allowing the retractable step to automatically descend to an extended position. The user places a foot on the lower step portion of the retractable step to assist in mounting a saddled animal. After mounting the saddled animal, the user engages the upper lift portion with his boot and raises the retractable step to a retracted position whereby the latch holds the retractable step in the retracted position adjacent to the main stirrup.

Abstract: An inkjet printer printhead has a layering of a flexible polymer tape, a patterned barrier material that is acting as an adhesive as well as ink channels, and a substrate that has a plurality of ink expulsion devices. Each of the ink propulsion devices is aligned with an orifice hole ablated in the flexible polymer tape where the ink expels and patterns the medium beyond. To keep adhesives and encapsulants required in the assembly of the inkjet printer printhead out of the critical ink channel area near the orifice holes, fluid accumulation channels are ablated into the flexible polymer tape in a strategic location between the adhesive bead and the ink channel. These accumulation channels function as both a diversion a containment point for the excess flow of adhesive.

Abstract: The present invention is a fluid level sensing system which has a single light source for providing light rays and a single light receiving device for receiving the light rays. The fluid level sensing system also has a fluid container which has a plurality of controlled surfaces arranged on the fluid container. Each controlled surface exhibits a first reflected light characteristic if fluid within the fluid container is in contact with the controlled surface and a second reflected light characteristic if the fluid is not in contact with the controlled surface. The controlled surfaces are disposed on the fluid container so that the light rays from the single light source impinge upon each of the controlled surfaces to produce either the first or the second reflected light characteristics and are thereby detected by the light receiving device to determine the fluid level in the fluid container.

Abstract: A method and apparatus for determining an optimum print density for an ink jet printer uses characteristics of a printer and its peripheral components such as an ink jet printhead, and an ink supply unit to reach an optimum print density. The ink jet printer receives a print command from a computer. The printer reads an ink drop volume parameter from a printhead memory device on the ink jet printhead and stores this parameter in a printer memory device on the ink jet printer. The processor in the printer determines an ink density compensation value for the ink jet printhead based on the ink drop volume parameter. The processor on the ink jet printer applies the ink density compensation value to the print command, thereby creating a depleted print command. Finally, the depleted print command is printed.
