Abstract: A magnetic positioning system is provided for assisting in positioning a fastening element at a desired concealed internal location such as in a preformed opening in an interlocking nail in a long bone of a limb of a patient who has suffered a bone fracture. The arrangement includes: a first permanent ("target") magnet positioned at the internal location and a positioning device for a second permanent ("targeting") magnet. The positioning device comprises a hand-held drill and a magnetic aiming device mounted on the drill. The aiming device including a pivot member including the second magnet is disposed at one end thereof and having an axial bore. A mount for the pivot member permits three degrees of movement of the pivot member so as to enable the second magnet to align with the first magnet. The positioning device also includes a guide pin which is insertable into the axial bore and which is engaged by the drill chuck of the drill when the magnets are aligned.

Abstract: An ornament for hanging from a support, such as a Christmas tree. The ornament includes a body portion and a headpiece portion. The headpiece portion is supported above the body portion and both portions are suspended from a support. The headpiece can be configured to represent a helmet or a cap. Alternatively, the headpiece can resemble the face of a sports personality. The body portion comprises a torso portion and a leg portion which is suspended from the torso portion. The headpiece, torso and leg portions are connected together to allow for movement in a way that simulates human action. Additionally the headpiece, torso and leg portions can depict an athletic uniform.

Abstract: A target for use in interactive target practice by a shooter firing bullets thereat with a controller for controlling the target's operation. The target includes a target plate, indicators, such as lights, for indicating that a practice round has begun, a target sensor, such as a vibration sensor switch, for detecting when the target plate has been struck by a bullet, and a firing mechanism for firing a projectile, such as a paint ball, at the shooter if the shooter does not hit the target plate within the allotted time. The target plate is hingeably attached to a target stand, a shock absorber is provided for absorbing the impact of bullets upon the target plate, and both the target plate and the target stand are angled forwardly downwardly so as to minimize ricochet of bullets back at the shooter.
Abstract: A double roasting pan that has identical pan halves that fit together to form the double roasting pan. There are diagonally arranged protrusions and recesses provided on the pan halves which fit together to prevent shifting of the pan halves relative to each other. Even if the pan halves are turned into either one of two positions 180.degree. relative to one another they will still fit. The protrusions and recesses on each pan half are "axially symmetrical" relative to the particular pan half. Rigid handles are provided on the pan halves with the handles being incorporated into the one piece construction of the pan halves, and disposed so that when the pan halves are placed together to form the double roasting pan the flanges on the handles of one of the pan halves are spaced from the flanges on the handles of the other of the pan halves so that room is provided to accommodate a gloved or mitted hand of the user when picking up the top one of the pan halves.
Abstract: An apparatus for biasing a portion of a seat belt shoulder harness away from a portion of a human chest. The apparatus comprises a body portion including a first end portion, a second end portion, and an intermediate portion. The body portion is deformable between a first and a second position. In the first position the intermediate portion is substantially non-coplanar with the first and second end portions, and in the second position, the intermediate portion is substantially coplanar with the end portions. The body portion is biased in the first position and is secured to the seat belt shoulder harness.
Abstract: Instrumentation for and a method of sizing the end of a distal femur, and resecting the distal femur. An instrument body construct is provided with an instrument body and a valgus module for attachment to the instrument body. The instrument body construct has a distal aspect abutting surface with a planar face for abutting the distal aspect of a distal femur at a fixed angle to the longitudinal axis of the distal femur, having a posterior aspect abutting surface with a planar face for abutting the posterior aspect of the distal femur, and having a passageway therethrough. An anterior feeler gauge is provided for attachment to the instrument body construct and for contacting a portion of the anterior aspect of the distal femur to indicate the anterior-to-posterior size of the distal femur. A resection guide is provided for attachment to the instrument body construct for guiding a bone resection tool to resect the distal femur.
Abstract: A compression hip screw plate for a hip screw system used to compress a proximal femur having a shaft with a lateral aspect and a neck extending from the shaft at an anteverted angle, both of which follow the anatomical contours of the proximal femur. The compression hip screw plate may include a side plate having a face side attachable to the lateral aspect of the shaft of the proximal femur; and a barrel having a first end extendable through the lateral aspect of the shaft of the proximal femur and into the neck of the proximal femur, and having a second end attached to the side plate with the first end extending away from the face side of the barrel at an anteverted angle. The compression hip screw plate may include a side plate with an anterior bow to match the natural femur.

Abstract: A fishing float apparatus for floatably supporting a fishing line in a body of water. The device includes a body member; a balloon attached to the body member, the balloon having a deflated position and an inflated position; a protective cover for covering the balloon when the balloon is in deflated; a pump for inflating the balloon; and attachment structure for attaching one end of the fishing line to the body member.
Abstract: A lamp base and a lamp base kit having component parts capable of being compactly packaged and quickly and easily assembled into a lamp base by a customer. The lamp base kit includes three separate connectors respectively having internally threaded openings therein and includes a pair of tubes respectively having externally threaded portions on the ends thereof which are adapted to respectively threadedly engage with the threaded openings in the connectors when the lamp base is assembled to establish a pole. The lamp base further includes a stand, and a lamp and shade holder which respectively have fixedly attached thereto one of the connectors. The stand includes three disconnected legs and a mounting hub. Each of the legs has a recessed socket and a hole through one end thereof. The recessed sockets of the legs are adapted to respectively receive pins which are fixedly attached to the hub. Each of the legs in addition has a hole therethrough.
Abstract: A bucket elevator filter apparatus including a filter unit for removing fugitive airborne particles from air; the filter unit having an inlet for receiving air, a filtered air outlet for discharging filtered air, and a filtered particles outlet for discharging filtered particles; and structure for attaching the filter unit to the hollow casing of a bucket elevator, for forming a passageway between the interior of the hollow casing of the bucket elevator and the inlet of the filter unit, and for allowing air to pass from the interior of the hollow casing of the bucket elevator into the inlet of the filter unit.
Abstract: A furniture leg attached to the underside of the frame of a piece of furniture. The furniture leg has a vertical bore through which a bolt is threadedly screwed into an internally-threaded insert on the frame, entrapping the furniture leg between the head of the bolt and the frame. In some embodiments, at least one, and preferably two, teeth extend upwardly from the upper surface of the furniture leg and pierce through the upholstery and into the frame, preventing the furniture leg from rotating about the axis of the bolt. In other embodiments, at least one, and preferably two, corrugated joiners extend upwardly from the upper surface of the furniture leg and pierce through the upholstery and into the frame, preventing the furniture leg from rotating about the axis of the bolt. One of the corrugated joiners may span a seam between bondedly and abuttingly joined pieces of the furniture leg, thereby also providing additional structural joining of the pieces of the furniture leg.
