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:
Repair strips can be inserted between courses of shakes or shingles in a wooden shake or shingle roof. The repair strip has a thin upper edge for insertion into the interface between two courses of shakes or shingles. A lower part of the repair strip is structured to provide air channels on one or both of its top and bottom faces. Gripping members may be provided to hold the repair strips in place.

Abstract:
An exercise apparatus and method are provided for permitting a seated user, such as a wheelchair occupant, to perform a variety of exercises, primarily lower extremity exercises but also upper 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. The first and second foot assemblies are mounted on the support base to permit selective performance and switching between a pivoting exercise and a translational sliding exercise.
Abstract:
A seed meter is provided with a stationary housing having an inlet for receiving seed and an outlet for dispensing metered seed. A rotatable circular member is located adjacent the stationary housing and forms a seed puddle there between. The circular member is provided with seed receiving cells for transporting individual seeds from the seed puddle to the outlet. An internal seed knockout assembly having a rotatable wheel drives trapped seed from seed receiving cells into the outlet.
Abstract:
A joist bridge has a web extending between a pair of end members. The web has a straight edge and an edge having a central indentation. The indentation provides a space through which plumbing pipes, electrical conduits and wiring and the like can be run. The joist bridge is economical of material and is therefore relatively inexpensive to manufacture. An adhesive strip may be provided along the top of the joist bridge to bond the joist bridge to the flooring above.
