Patent number: 6715437Abstract: Leakage detection of cargo from the hold of a barge involves a mounting plate to the top hatch of the hold. Two pipes secured to the plate extend to locations near the bottom. Each pipe has a guide tube in it coaxial with the pipe. Each pipe has a float in it received around the guide tube. A float follower is in each tube and magnetically coupled to the float so that the float follower rises and falls with the float. One pipe has an open bottom for cargo to freely move up and down in the pipe as the hold is filled and emptied. The other pipe has a valve at the bottom for admitting cargo from the hold to the pipe at the port of origin of the vessel. Following loading of the cargo, the valve is closed. One embodiment tethers the floats to reels atop the plate. Any change of level of the floats, reflecting a loss of cargo during transit from the port of origin to that of destination, is reflected in relative rotation of the reels and triggering an output signal to an annunciator.Type: GrantFiled: January 24, 2003Date of Patent: April 6, 2004Assignee: Electromechanical Research Laboratories, Inc.Inventor: Larry C.

Patent number: 6715438Abstract: A tiller is preferably coupled to the outboard motor or other steered element of a watercraft such that movement of the tiller in a first manner imposes manually-generated steering forces on the steered element and that operation of the tiller in a second manner imposes power assist steering forces on the steered element. The first manner preferably involves movement of the tiller as a whole, in which case tiller movement drives the steered element mechanically. The second manner preferably involves movement of an actuator portion of the tiller relative to the remainder of the tiller, in which case movement of the tiller actuator portion causes a steering cylinder assembly, an electric stepper motor, or other drive mechanism to impose power assist steering forces on the steered element. The actuator portion of the tiller may, for example, comprise an articulating end of the tiller's arm or a throttle grip supported on the tiller.Type: GrantFiled: October 15, 2002Date of Patent: April 6, 2004Assignee: Mark X Steering Systems, LLCInventor: James M.

Patent number: 6715468Abstract: An excessive volume of fuel discharged by a high-pressure supply pump to a common rail due to an opened state abnormality of an inlet metering valve of the pump may result in an abnormal increase in common rail pressure. In the event of such an abnormal increase, a target idle revolution speed is newly set at an abnormal value greater than a normal value as a measure taken to increase an idle revolution speed. Thus, a pressure limiter, which has been once put in an opened valve state by an actual common rail pressure higher than a limit setting pressure, can be prevented from again entering a closed valve state. As a result, it is possible to eliminate idle performance instability caused by repetition of opened valve and closed valve states of the pressure limiter and, hence, assure reliability of the pressure limiter.Type: GrantFiled: November 4, 2002Date of Patent: April 6, 2004Assignee: Denso CorporationInventors: Ken Uchiyama, Toshimi Matsumura

Patent number: 6715477Abstract: An apparatus that simulates punting and place kicking of a ball includes a prosthetic leg having a mechanism in the foot region to seat a ball. The leg is pivotally-mounted to a frame and mechanically coupled with a foot pedal. Downward force on the foot pedal is translated to the leg causing the leg to whip upward and launching the ball with proportional force and speed. In one embodiment, the frame is collapsible/expandable and includes a roller to facilitate transportation. In another embodiment, the leg is formed of pliable material to eliminate the risk of injury in the event of collision therewith.Type: GrantFiled: December 12, 2002Date of Patent: April 6, 2004Assignee: Marty Gilman, Inc.Inventor: Neil F.

Patent number: 6715478Abstract: A ball pitching machine utilizes a leaf spring coupled by linkage to a ball pitching arm. The flexion of the spring can be adjusted by varying the time of operation of a motor driven spring flexion assembly. Upon the selectable spring flexion being achieved, the user then energizes a ball pitching arm for rotation of the arm through a rest position, a ball pick up position and then to a ball release position. During arm rotation, the arm is first coupled to the spring by a linkage assembly such that further rotation of the arm causes the stored energy in the spring to be released to the arm at a position to effect the ball trajectory. The ball trajectory compensates for the various ball speeds so that the ball penetrates the batter's strike zone. This energy transfer accelerates rotation of the arm to a ball release position, the speed of the ball, as perceived by the batter, corresponding in part to the spring flexion and/or ball trajectory as selected by the user.Type: GrantFiled: December 31, 2002Date of Patent: April 6, 2004Inventor: Steven R.

Patent number: 6715479Abstract: A torqueless buss cable positioner for a compound bow which is fixedly mounted thereto, whereby the buss cables are displaced from the bow plane, yet, optimally, the buss cables do not subject the limbs to any force component perpendicular to the bow plane. A guided path for the buss cables is provided which includes first and second outboard guidance component for guiding the buss cables generally in the bow plane and an inboard guidance components for guiding the buss cables laterally off from the bow plane. The first and second outboard guidance components optimally ensure that the limbs are not subjected by the buss cables to any component of force perpendicular to the bow plane, and the inboard guidance component ensures that the buss cables are laterally displaced in relation to the bow plane sufficiently to be out of the way of the arrow and the sights of the compound bow.Type: GrantFiled: February 21, 2003Date of Patent: April 6, 2004Inventor: Paul H. Bunk

Patent number: 6715480Abstract: A high flow bolt for a paintball marker increases the efficiency of energy transfer from a propellant charge to the paintball projectile by increasing the flow rate of propellant through the bolt. Gradual transitions, increased sectional area flow passages and an equalizing chamber synergistically combine to improve the efficiency of the marker by up to 30% or more. A more efficient marker provides more shots per unit of propellant.Type: GrantFiled: June 27, 2002Date of Patent: April 6, 2004Assignee: New DesignzInventor: David F. Dziob

Patent number: 6715481Abstract: A novel handheld compound archery bow (100) includes a riser (102) with a keyhole (410), an arrow rest assembly (150) extending through the keyhole (410), a bowstring (130), and a side grip assembly (180) with a side grip (201) and an arm brace (116). The side grip (201) is attached to a side grip base (112) and extends in a substantially perpendicular direction from the plane of the novel bow (100), formed by the center line of the arrow rest assembly (150) and the bowstring (130). The valley (202) of the side grip (201) is substantially opposite to the bowstring (130) to provide a zero brace height. Since the brace height is substantially zero, the power stroke of the novel bow (100) is the entire full-draw length. As a result, an embodiment of the novel bow (100) with axle to axle length of 37 inches is capable of AMO and IBO arrow speeds of 264 and 333 feet per second, respectively.Type: GrantFiled: November 29, 2002Date of Patent: April 6, 2004Inventor: Jeffrey R. Anderson

Patent number: 6715486Abstract: A dry powder inhaler has a dispersion chamber containing beads. A dose of dry powder is released into the chamber, or into an inlet tangentially joining into the chamber. As the patient inhales on a nosepiece or mouthpiece, air moves circularly through the dispersion chamber to drive the beads. The beads roll, bounce, and collide repeatedly with the drug particles on the chamber surfaces or on the beads. The smaller active drug particles are separated from the larger carrier particles and from each other, and a powder aerosol is created and inhaled by the patient. The beads are preferably lightweight, so that they can be rapidly accelerated and moved, even with nominal inspiration. The flow resistance of the inhaler is also reduced via the beads, allowing greater air flow and powder dispersion, without any increased effort by the patient.Type: GrantFiled: January 31, 2001Date of Patent: April 6, 2004Assignee: Quadrant Technologies LimitedInventors: Andrew W. Gieschen, Michael Ligotke, Jeffrey Chen, Charles Ganem, Bernard Greenspan
