Abstract: The invention relates to an eyeglass frame having a portion of the frame removably coupled to the body of the frame to permit the removal and replacement of the lenses in the frame. The frame includes a shoulder member that serves as a retainer plate and includes a leg portion and a recess located between the leg and a rear portion of the frame. A mechanism for disengaging the recess member can be accessed through the recess and pull of the leg portion to release the retaining member so that lenses can be removed and inserted.

Abstract: By using a sheet beam and a charge-storing target measuring the differential of the deposited charge, one can greatly improve the performance of a scan converter. A segmented target provides instantaneous analog output.

Abstract: The present invention relates to an illuminated serving tray. The tray has a plurality of receptacles for housing products to be dispensed and a light source for illuminating the tray. The tray is made of photoluminescent material with a reflective label positioned above the central portion of the tray and in line with the light source which is connected to and positioned below the bottom of the tray so that the light from the light source and any ambient light is reflected back by the reflective label and transmitted through the photoluminescent material of the tray causing the tray and the edges of the tray to glow.

Abstract: The present invention relates to an indoor and an outdoor decorative lighting system. The invention includes a lighting string, preferably of 18 light bulbs and a plug for putting into an outlet, a number of globes, preferably made of plastic and each having one of a variety of colors, and connecting elements for connecting the light bulbs to an opening in the globe. The connecting members have external elements for engaging internal lip in the sleeve shaped opening of the globe and internal rib members for engaging and securing the light bulb in place within the connecting member.

Abstract: The present invention relates to a board game and method of playing the game. The game involves a strategic means for defining paths along the game board. The game board is preferably configured as 9.times.9 lines, creating 64 squares with a black cross piece in the center. Each of the squares is raised, creating a recess therein in which pieces can be inserted. The inserted pieces include pawns and connector pieces. The connector pieces can either be I-shaped, L-shaped or T-shaped, or cross-shaped. Each player is provided with a set of pawns and connector elements as described above. The object of the game is to start at the center cross section, each player to continue with his pawn and connector piece, thereby defining the paths that the next player can take. The game is played until an opponent can move no further, or the opponent with the fewest pieces on hand at the end of the game wins.

Abstract: The invention relates to a ring and a method of making the same. The ring has a ring made of PVC material such as FIMO clay and having a hole made, preferably drilled through from one side of the ring head to the other side. A strand of material such as a wire is threaded through the hole. The trailing end of the wire is shaped as a catch and then partially embedded into the side of the ring head. The leading end of the wire is then threaded through beads preferably colored beads whose colors match the designs that are preferably displayed in the faces of the ring head. The leading end is threaded a second time through the hole of the ring head. Any excess material not needed for the ring is then removed by breaking it off or cutting it from the strand. The lead end is then shaped as a catch and at least partially embedded into the opposite side of the ring head.

Abstract: A hinge assembly for interconnecting and stably supporting the parts of an electronic device while enhancing the three-dimensional adjustability of the position of the device's parts. The hinge assembly provides for lineal adjustment of each device part using a shaft secured to the part, a sleeve slidably attached to the shaft and a clamp controlling the resistance of the sleeve. The hinge assembly further provides joints for rotational adjustment of each device part about an axis parallel to the part's horizontal axis and about a rotational axis parallel to the part's latitudinal axis. Each axis is formed using a first element having a substantially cylindrical aperture and a second element having a substantially cylindrical end such that the cylindrical end is rotatably mounted in the cylindrical aperture. An electrical connector is included in each joint to pass electrical signals regardless of rotational position.

Abstract: The present invention relates to a hip prosthesis and a method of implanting the same utilizing dual modes of fixation. The prosthesis has a proximal portion which is porous coated to permit bone ingrowth. The prosthesis also has a distal stem portion which is adapted to be affixed by cementation. In addition, there is a tapering at the junction between the distal stem portion and the proximal portion. The prosthesis is implanted by reaming and broaching the femoral stem of a patient so that it can have a prosthesis' porous portion in contact with the bone proximally and still have channels between the bone and the distal stem portion which are cement filled. In addition this design also allows an improvement in cementation technique by providing an improved bone-cement interlock by more efficient pressurization.

Abstract: A dynamometer comprising a first member, a second member which is movable relative to the first member along a predetermined path, a piston and cylinder arrangement for resisting movement of the second member with respect to the first member in one direction along the predetermined path with a force which increases from zero with the distance moved from a rest position, and a potentiometer having a first elongate resistor element having two ends and a second wiper element which is in electrical contact with the resistor element and is movable with respect thereto to establish an electrical resistance between the wiper element and one end of the resistor element which increases with relative movement of the elements in one direction.
