Abstract: A two piece humeral component for use in shoulder arthroplasty which is adapted to be implanted into a humerus and engaged by a glenoid component of a scapula. The humeral component includes a body having a first articulating surface and a second medial surface opposite the first articulating surface. The first articulating surface is adapted to be engaged by the glenoid component and the second medial surface is adapted to be secured to mounting portion. The mounting portion has a first surface and a second medial surface. The first surface is adapted to be fixably engaged to the second mounting portion of the humeral component. The second medial surface is adapted to be secured to the humerus. A peg which has a first end adapted to engage a cavity found in the humerus is disposed on the mounting portion's second medial surface.

Abstract: A horizontal rooftop engine cooling system includes one or more radiator units horizontally mountable to the rooftop of a bus and including a radiator interconnected to one or more passages of an engine of the bus to allow coolant to flow between the engine and the rooftop cooling system to cool the engine. The cooling system can incorporate a fan mounting shroud, a ram-air aerodynamic shroud, and/or an ornamental aesthetic appearance shroud.

Abstract: An apparatus, method, and system for lighting includes one or more moveable bases, one or more lighting arrays, and one or more extendable poles. The base, pole, and array are designed to allow elevation of the array to heights exceeding 35′, yet the combination is transportable by conventional over-the-road trucks. In one form, a plurality of bases, poles, and arrays are designed to fit on a conventional over-the-road trailer for transport on one trailer to a lighting location.

Abstract: A joint distraction device for facilitating joint arthroscopy disclosed. In the first embodiment of the invention, the distractor disclosed is a series of fluidly fillable spheroid members to form a toroid. The joint distractor is placed between articular cartilage surfaces and filled to hold the joint surfaces apart. In a second embodiment of the invention, a string of spheroidal members is disclosed. The spheroidal members have varying diameters and are used to separate the articular surfaces of a joint.

Abstract: An apparatus and method for providing a temporary spread footing for suppporting a variety of different vertically extending structures. The apparatus includes a frame with a top and bottom. The frame can have a substantial space or void in between the top and bottom into which weights or devices can be placed. A connection on top of the base removably connects to the structure to be supported. Outriggers could also be used to substantially increase the overturning moment resistance of the base. The outriggers can be removable or retractable so that for transportation, the base has minimum dimensions. The method includes pre-determining the needed weight and overturning moment resistance for a particular application and transporting the base to the site and thereafter adding weight and adjusting outriggers to match the pre-determined needed overturning moment resistance.

Abstract: A method and apparatus for delivering interactive television (ITV) data by using the same TV scan line that also carries closed caption data. The ITV data is inserted into the scan line with CC data by detecting a gap associated with a first CC data unit. If the gap is large enough to contain all of the group of ITV data units then electronically insert the entire group of ITV data units into the gap. If the gap is not large enough to contain the entire group of ITV data units, insert a subset of the entire group of the ITV data units into the gap and continue to the gaps associated with successive CC data units, inserting subsets of the ITV data into subsequent gaps until the entire ITV message has been inserted into the gaps between CC data units.

Abstract: An apparatus and method for elevating items includes telescopically retractable and extendable hollow tubular pole sections that include a locking means to lock at least one section in extended position. The bottom of the pole is adapted for mounting to a support structure.

Abstract: A lighting fixture with a controllable light block. The fixture includes a reflector and high intensity discharge lamp that requires a re-strike or warm-up period to come to full brightness or intensity. A cover member is mounted to the reflector and is moveable between an unblocked position and a blocked position. Movement of the cover member is immediate so that blockage of light from the fixture is immediately effectuated. The apparatus is configured so that cover member can be in the blocked position for indefinite periods of time even though the arc lamp continues to be operated at full power, without heat buildup which is detrimental to any part of the apparatus. The cover member also allows light control and special effects lighting options. Another aspect of the invention utilizes an aperture in the cover member that is alignable with the light source when the cover member is in the blocked position.

Abstract: A construction system suitable for erecting a modular structure such as a furniture item or the like. A first part is connectable with a second part by a releasable cross connection. A third elongate part has a cavity extending substantially over its full length for receiving the cross connection at a position therealong. The third part may be a leg member for the furniture item and the first and second parts may be rail members. Alternatively, the first part may be a coupling element for connecting modular structures together or a hinge element for pivotably attaching a door panel, the second part being a securing element for securing the coupling or hinge element to a leg member. A modular structure and a method of erecting a modular structure are also disclosed.

Abstract: An osteosynthesis plate. An osteosynthesis plate is disclosed having a regular knob profile, preferably a spherical knob profile, whereby the knob height, measured between the deepest profile point and the peak of the knobs, is between a selected optimal range of heights, and the distance between successive knobs, measured between the highest points of two successive knobs, is between a selected optimal range of distances.

Abstract: Polyurethane/urea elastomers having an isocyanate equivalent index below 100, preferably from about 15 to about 80; containing an effective amount of polyisocyanate component, and an effective amount of an isocyanate reactive component comprising at least one polyamine and at least one polyol, wherein said elastomer contains from about 1 to about 199 equivalent percent amine per isocyanate equivalent.

Abstract: A dispenser for flowable materials such as creams, includes a pair of open ended containers nested telescopically with each other at their open ends, with the upper container having a dispensing orifice formed therein adjacent its upper end and containing a hollow dispensing channel communicating at one end with at least a portion of the orifice and having its other end located adjacent the open end of the upper container. A piston is received in the upper container for sliding movement with respect to the dispensing channel and has a hollow rod operatively connected to it which telescopically engages the dispensing channel. This hollow rod has a bottom end that engages the closed end of the lower container and also has an opening formed therein adjacent its bottom end to provide communication between the interior of the lower container and the hollow rod.
