Abstract: A method of providing an implement for removing debris from a transport track of an article processing machine. The method includes providing a strip of non-conductive material, such as polycarbonate resin sheet material. The strip has a generally rectangular configuration and includes a plurality of corners. The strip is adapted to define a hook-shaped structure at each one of the corners, and the hook-shaped structure includes a hook-point that coincides with the corner of the strip at which the hook-shaped structure is located. The strip is modified to define a concavity proximate each of the corners, the hook-point being defined by an exterior edge of the strip and an interior edge of the strip defining the concavity. The hook-point as provided on the strip is suitable for engaging the debris and urging it along the transport track.

Abstract: The present invention is an inline ball valve shutoff tool for moving an inline ball valve handle used to open and close inline ball valves. The tool allows access to inline ball valves that are difficult to reach due to obstructions and height restrictions. The tool allows for access through the maze of conduits and other obstructions which block access to inline ball valves. There are approximately eighteen different sizes of pipe commonly used for supply lines and all require different sized inline ball valves and valves handles. Generally pipe lines run in either a horizontal or vertical direction. For pipes running in the vertical direction, the inline ball valve handles operate in a vertical plane. For pipes running in the horizontal direction, the inline ball valve handles can operate in either the vertical plane or a horizontal plane. The different components of the inline ball valve tool allows for movement of different sized valve handles that are in any of the positions described above.

Abstract: An improved conduit has a cross sectional profile which generally provides an elongate support structure having at least one anchoring structure extending from the support structure to engage any groove on a base board structure to enable the conduit to be "snapped" into a place of consistent support. Generally, the conduit will be pushed down directly against the support structure to enable the support structure to either become anchored or to flex against and secure the engagement of the anchoring structure. A variety of embodiments take advantage of the widest variety of corner configurations in order to provide the widest applicability of the conduit. A tool is disclosed to facilitate installation of the conduit.

Abstract: An apparatus and method for positioning a latch assembly and a striker on a motor vehicle is disclosed. The apparatus is designed to improve the fit of the tailgate to the side walls or truck body. A good fit is defined as the outer surface of the tailgate and the outer surface of the side wall being coplanar when the tailgate is in the closed position. The apparatus, by way of a first formation and first locating element, determines the position of the latch assembly with respect to outer surface of the tailgate. The apparatus, by way of a second formation and second locating element, also determines the location of the striker with respect to the outer surface of the side walls. The apparatus, by way of a body member, also determines the position of the striker with respect to the latch assembly and vice versa. By setting the latch assembly and the striker by the above relations, build variances of the tailgate and of the truck body are eliminated as a possible cause for a poor fit.

Abstract: A tool for disengaging the swing bar from a swing bar guard assembly engaged on an entry door to a room where such disengagement is from outside of the room. The tool is formed from an elongate relatively flat shaft having a proximal handle end and a swing bar guard disengaging distal end. The tool has a centrally-disposed generally right-angle Z-bend for accommodating a door stop so that the distal end can be located inside the room when the door is shut. The distal end is centrally hinged to form an outer distal segment and an inner distal segment. The distal end also is biased to rotate the outer distal segment out of alignment with the inner distal segment. The tip of the outer distal segment retains an upstanding rod for contacting the swing bar of the swing bar guard.

Abstract: A release tool is provided to aid in the unlocking of extending towing arms. The tool is adapted to fit a tow bar assembly that has a telescoping towing arm which is locked in an extended position by a slideable collar. The collar is moveable between a locked position and a released position. When in the locked position, the collar holds catches in engagement with legs of the towing arm to hold the legs fixed relative to each other. When in the released position, the legs are free to telescope relative to each other. Stress can build-up in the towing arms making it difficult to move the collar from the locked position to the released position. The release tool of the present invention provides a mechanical advantage to aid in the movement of the collar from the locked position to the released position. A cam surface on the tool engages the collar and moves it from the locked position to the released position as a handle is rotated about a fulcrum means.

The tool allows carpenters, cabinetmakers, and other users the convenience of one hand operation in applying pressure to the entire surface of a plastic laminate or wood veneer. Specifically, an evenly distributed pressure is applied via the relatively large roller to the large easily accessible surface areas of the laminate, and via the narrow blade-like laminate edge presser to those typically inaccessible surface areas of the laminate, such as corners, edges or butt joints.

Abstract: A key ring opener for spreading apart the adjacent end and intermediate portions of a split key ring that are spring-urged against each but are spreadable to allow a key to be placed on or taken off the ring. The opener includes an annular band having sharp circumferential wedging edges and is adapted to encircle such a key ring in the same way as a key, and along with keys on the ring, and a wedging bar extending diametrically of the band and having sharp wedging edges. The opener is slipped on and off the key ring like a key but is easier to do because of the sharp circumferential edges. While on the key ring, the bar can be wedged, again because of its sharp edges, between adjacent segments of the ring, ahead of a key, thereby to spread the segments apart. Thereafter, the band is rolled between the thumb and forefinger causing the bar to leverage the segments of the key ring farther apart thereby to facilitate entry and removal of a key to and from the ring.
