Abstract: An archery bow stand includes first and second legs having first and second connecting portions for engaging archery bow structure, and first and second support portions extending from the connecting portions for supporting the archery bow. The first and second legs are identical in construction and pivotally connected together. The first and second connecting portions together forming a hollow interior within which a biasing member is located to alternatively bias the legs toward the closed position and the open position. A pivot joint creates an internal gap so that the internal biasing member can travel across the pivot joint when the bow stand is opened and closed. Resilient overmolding on the legs protect the bow against damage when supported by the bow stand. Arcuate projections on each leg can be grasped by a user to facilitate opening and closing of the bow stand with one hand.

A locking flange is associated with one of the arm portions and is adapted to extend through an opening in the central body portion when the silencer is installed. The first and second arm portions extend asymmetrically with respect to the central body portion prior to attachment to a bowstring, buss cable or the like, and extend at least generally symmetrically after attachment thereto.

Abstract: A vegetable oil-based resinous composition comprises a metallization product of vegetable oil-based adduct, wherein the vegetable oil includes at least one unsaturated double bond. The vegetable oil-based adducts may include a Diels-Alder adduct, a ene reaction adduct, or combinations thereof. The metallizing agent may be selected based on various factors such as the types of substrates, the techniques of applying the composition to the substrate, and the end use applications of the composition. The resinous composition may be used as an alternative to a conventional rosin-based resinate binder for various end use applications such as printing inks, coatings, and adhesives on a variety of substrates.

Abstract: A consumable supply item for an imaging device holds an initial or refillable volume of ink. An interior retains the ink while exit and return ports define openings through a housing to fluidly communicate the interior to the imaging device. The opening of the return port is larger than the opening of the exit port. The design slows the return of fluid to the housing which minimizes air bubbles or frothiness in the fluid. During use, ink depletes toward a bottom surface of the interior beneath which the ink is prevented from occupying. A housing section below the interior retains a portion of the exit port so that a bottom of the opening of the exit port is substantially horizontally aligned with the bottom surface. It prevents stranding ink beneath the exit port. Further embodiments include port configuration, construction, and modular components, to name a few.

Abstract: A consumable supply item for an imaging device holds an initial or refillable volume of fluid. Its housing defines an interior having a pair of opposed electrodes. The electrodes define a capacitance that varies in response to an amount of liquid between them. A volume space filled by the liquid varies along a length of the electrodes. The design facilitates abrupt changes in capacitance values at each change in the volume space. Devices can recalibrate fluid levels at these changes. Electrode interior surfaces face one another. At least one electrode has an open region, such as a hole or a cutout of material. In another design, a support material connects to each electrode to provide mechanical stability and create a region preventing filling by the liquid. Further embodiments contemplate material selection, construction, and modularity, to name a few.

Abstract: A housing defines a fluid reservoir for an imaging device. One or more exterior walls define a volume for holding ink to set a fluid backpressure in the imaging device. An opening in the walls is positioned for overflowing excessive ink from the volume to maintain the fluid backpressure within a predetermined operating range. Fluid inlets and outlets connect the reservoir to both a supply item and an ejection head. Ink flows into the reservoir from the supply item. It fills until the fluid rises to a height where it overflows back to the supply item. Less full reservoirs fill as the pump operates, while full reservoirs simultaneously return fluid back to their supply containers. Fluid does not spill from the walls.

Abstract: A weight exercise machine may include an exercise member, one or more weights, and one or more weight selectors. When using the machine to exercise, the user exerts an exercise force against the exercise member. A weight selector may be rotated, pivoted, or otherwise moved to operably couple the exercise member to at least one of the weights such that displacement of the exercise member causes at least one of the weights to displace, thus providing resistance to displacement of the exercise member. The weights may include main weights and add-on weights for operative coupling to the exercise member via a movable frame. The one or more weight selectors allow for selection of different combinations of weights for providing resistance to displacement of the exercise member.

A linkage mechanism operably associates the upper and lower carriages together to allow coordinated movement relative to one another. The upper carriage includes an upper pivot axis relative to the frame, and an upper carriage pivot axis relative to the upper carriage, and the lower carriage includes a lower pivot axis relative to the frame.

Abstract: An exercise machine composed of a frame, a first four bar linkage system, a second four bar linkage system, and a means for transferring an incident force from the legs of a user is disclosed. The first four bar linkage system is operably mounted on the frame and operably connects the transferring means to the frame to allow for back and forth movement of the transferring means along a path of travel about an instantaneously changing axis of rotation. The second four bar linkage system operably engages the first four bar linkage system. Either or both of the first four bar linkage system and the second four bar linkage system are operably connected to a resistance means, whereby the second four bar linkage system operates in conjunction with the first four bar linkage system and the resistance means to create a mechanical disadvantage to the user.
