Abstract:
The present invention generally provides mold modules for constructing boat hulls, methods of constructing boat hulls using the mold modules, and hulls constructed using the mold modules. The modules may be adjustable, and may be included in a kit for building the hull of many boats of different dimensions but generally the same shape. Each mold module generally comprises a mold in a shape complementary to that of a portion of a boat hull, and an edge mold to form the edge of the hull part formed by that mold module. A mold module according to the present invention may also comprise one or more mold adjustment areas, and calibrators for selecting the boat hull dimensions. Methods for using the aforementioned mold modules generally comprise steps of molding hull parts, removing them from the mold modules, aligning them and finally attaching them together.
Abstract:
Left and right main hoppers offset laterally from each other on opposite sides of the centerline of a seeding machine provide an operator access area between the hoppers. A third hopper located forwardly of and between the two main hoppers has a capacity less than that of each of the main hoppers for refuge or male seed. The hoppers are sized to maximize productivity. In one embodiment, first and second hoppers communicate with downstream conduit structure, and valve structure selects one or the other of the first and second hoppers for delivery of the material. The valve structure can be operated remotely and can be map based. Alternatively, selectively blockable nozzle structure is located in the first and second hoppers. Easily changeable connector structure facilitates row pattern selection and hose routing.
Abstract:
A mobile illumination apparatus. A universal clamp for attaching to wide range objects such that a broad range of clamping abilities are achieved. Incorporating into the clamp a self-locking ratcheting mechanism for adjusting over a range of spans and fold-out fingers for applying force to the object; the clamp folds up against or into the apparatus for transport or storage. An extendable-and-retractable neck mounting for a transducing-element head thereon, for activating-deactivating the transducing-element, and moving the head to hold an orientation so as to illuminate a region-of-immediate-interest or a particular target. Drive and control circuitry to maintain the illumination intensity substantially constant.
Abstract:
An exercise apparatus and method are provided for permitting a seated user to perform a variety of upper and lower body exercises without the need to leave a seated position. According to one embodiment, the exercise apparatus includes a support base, and first and second foot assemblies each configured to receive a respective foot of a seated user of the apparatus, and a pulley assembly. The pulley assembly has a pulley line and a hand-graspable component that is manipulable by the seated user for performing upper body exercise movements, while at least one of the foot assemblies provides resistance for the upper body exercise movements.

Abstract:
A product-on-demand delivery system applies an agricultural product, such as seed, to a field. The system includes a frame that mounts a main hopper, a splitter fitting, a primary product hose, a secondary product hose, a primary application unit and a secondary application unit. The main hopper has an air nozzle wherein an air stream through the air nozzle entrains product within the air stream and delivers the air/product to the primary outlet hose. The splitter fitting has a splitter inlet flow-connected to the primary product hose and two splitter outlets flow-connected to the application units. The secondary application unit is coupled to the primary product supply hose by the secondary product hose connected at an outlet branch. The outlet branch is connected at an angle such that a product flow velocity vector in the primary product supply hose at the outlet branch is at an obtuse angle to a flow velocity vector of product flowing through the outlet branch. The outlet branch is oriented for a vertical upward flow of air and product.
Abstract:
A portable leg exercise device is provided for permitting a user to perform both adductor thigh muscle movements and abductor thigh muscle movements.
Abstract:
A pneumatic coupler for an agricultural seeding machine comprises a hollow tube having an inner portion and an outer portion that are separated by a radially extending flange. The radially extending flange has an inner surface adjoining the inner portion and an outer surface adjoining the outer surface. A flexible and resilient gasket is fitted over the inner portion and adjoins the inner surface of the radially extending flange. The inner portion is further provided with radially extending catches that are located on resilient axially extending tongues formed in the inner portion. When mounted to receiving apertures the catches contact the interior side of the receiving aperture and the flexible and resilient gasket forms an air seal between the exterior surface of the receiving aperture and the inner surface of the radially extending flange.
