Abstract: The present invention provides a parabolic dish reflector antenna for wireless communications that is dually polarized for diversity reception purposes while causing minimal visual disturbance for use with cellular base stations and repeaters. The antenna comprises a reflector of paraboloidal shape along both the longitudinal and latitudinal axes of its diameter. The reflector of the antenna is comprised of 4 identical quadrants assembled at the installation site, where each quadrant is made of thin metal ribs with large openings metal mesh stretched and attached to the ribs. The antenna further comprises a feed that is located around the focal point. The antenna feed comprises an open cup-shaped conductive cavity wherein the two orthogonally mounted feeding elements of the antenna located within its volume, are low cost printed circuit board elements.

Abstract: The present invention provides a unique and novel internal fixation for fixing an intracapsular and extracapsular including substochanteric fracture of a femoral neck while using minimal invasive procedure. The fixation comprises a hollowed or full tubular member having a sharp end and a blunt end that is adapted to be implanted while slightly crossing the fracture line. The tubular member is provided with three passages that extend from the sharp end to the blunt end. Three lag screws are adapted to pass through the passages and extend outwardly beyond said sharp end while thread that is provided in the lag screws so as to allow compression of fragments of the bone. The lag screws are provided with screw heads so as to prevent the screws from being fully inserted into the passages and through the trochanteric cortical bone.

Abstract: An adjustable position tool guide is disclosed for performing operations with tools on a work piece at an accurate distance and orientation with respect to edges or other features of the work piece in a highly convenient manner. The tool guide includes a base for positioning on the work piece. The base has a base edge for aligning in a substantially parallel orientation to a longitudinal axis of the work piece, and a work edge oriented perpendicular to the base edge for being oriented perpendicular to the longitudinal axis of the work piece when the base edge is aligned parallel with the longitudinal axis. The guide also includes a tape measure mounting assembly mounted on the base for mounting a tape measure on the base. The tape measure mounting assembly is slidably moveable on the base along a line oriented substantially parallel to the base edge of the base.

Abstract: A manhole cover remover, including an attachment; a support; a pivot arm having a proximal end hinged to the support and the pivot arm having a distal end; a connector joining the attachment to the distal end of the pivot arm; a winch joined to the distal end of the pivot arm; and a power source, the power source in operable communication with the winch and method of use including the steps of rotating a pivot arm down toward a manhole over; connecting the pivot arm to the manhole cover; and winching the pivot arm upward.

Abstract: A snowmobile seat, including a base; selective fasteners mounted to the base, the selective fasteners including inner posts and offset outer posts on a first side of the base and on a second side of the base, the inner posts and outer posts defining a groove; a flexible support having a first side and a second side, the first side being interposed between the inner and outer posts on the first side of the base, the second side being interposed between the inner and outer posts on the second side of the base, the flexible supported being bowed, the flexible support being adapted to support the weight of a rider, and the flexible support defining apertures; a foam overlay disposed over the flexible support; and a fabric overlay disposed over the foam overlay.

Abstract: A scaffold system, including a plank; at least one end support having a plank bracket, the plank engaging the plank bracket, the end support having adjustable legs, and the end support having at least one cross bar interconnecting the legs; a moveable tray including a plank attachment, a vertical support and an upper horizontal support, the vertical support interconnecting the plank attachment and the upper horizontal support, the plank attachment having a hook end adapted to encase an edge of the plank; and a material support bracket including a plank securement and a material support, the plank securement releasably and slidably joined to the plank, the material support adjustably joined to the plank securement.

Abstract: A cover for a liquid container having a mechanism for selectively attaching the cover to the liquid receptacle, a valve centrally located upon the cover, the valve being adapted to either allow the flow of liquids or disallow the flow of liquids, the valve having a pair of outwardly extending hinged ears pivotal to urge the valve into the on position; a pair of spacing horns formed on the cover, each horn extending upwardly and coaxially from the top surface of the cover proximate the periphery of the cover.
