Abstract: The present invention provides a method for laser brazing a first member to a second member using a laser brazing head. The laser brazing head has means for generating a first laser beam and a second laser beam. The method comprises the steps of: arranging the first member in contact with the second member such that a junction is formed there-between; providing a filler material in the vicinity of said junction, and passing the laser brazing head along the junction such that the first laser beam melts the filler material to at least partially fill said junction to form a brazed joint. The second laser beam then effects a post heat treatment of the brazed joint.

Abstract: A combination chair and ladder assembly including a center leg, a rear leg and a front leg wherein the rear leg is pivotally connected to the center leg and swings outwardly away from the center leg. The assembly includes a lower step or platform assembly including a first platform having first and second portions with a hinge connecting the first and second portions. The front leg is connected to the first platform. In addition, the chair and ladder assembly may include an upper step or platform assembly having a plurality of platforms pivotally connected to the center leg and to a front support member. The lower step or platform assembly operates independently of the upper step or platform assembly.

Abstract: A versatile mobile utility cart or vehicle using either tracks, wheels or both for suspension and steering with propulsion coming from but not limited to an internal combustion engine or an electric motor. The vehicle is meant to be a utility workhorse with the ability to load and unload itself as well as drag or carry materials. The vehicle can be configured in many ways to do many tasks with the main feature being labor savings. One of the unique features of the vehicle is a loading system called a fork and foot system. For transport the forks and feet system can be raised or detached individually or as a system, this is beneficial when unloading. The foot may remain attached and used for stability. Detaching the fork and foot system as a system allows the vehicle to be used for other tasks including but not limited to: a dump vehicle; a skidder; a reel carrier; a fork lift/carrier; and a prime mover or base for brush chippers, stump cutters, tree spades and more.

Abstract: A vehicle bumper and a method for making a vehicle bumper formed of first and second members. Each of the first and second members are formed of substantially similar first and second U-shaped members positioned such that the respective sidewalls of the first and second U-shaped members are positioned adjacent one another. The bumper including a plurality of apertures therein formed by cutouts extending inward from the peripheral edge of each of the first and second U-shaped members.

Abstract: A composition for use with clipper blades of the type used for cutting hair. The composition including a base ingredient typically comprising mineral oil and also including at least one additional member selected from the group of spearmint oil, peppermint oil, fatty acids, fatty oils, hydraulic oil or mixtures thereof.

Abstract: A structure for a musical instrument body that limits vibration of various components or parts of the body while controlling and providing for overall resonance of the instrument. The structure is suitable for use with a musical instrument, specifically an electric guitar. The structure includes a support member or block positioned in a chamber created between a top plate and bottom plate of the guitar body and a structural element, spaced from the top and bottom plates, that engages the block to provide additional support and stiffness enabling further control of the overall vibration and thus resonance of the instrument. Varying the design of the structure along with the various body components provides an apparatus for uniquely tuning the acoustic characteristics of the guitar body.

Abstract: A cutting tooth for use with a stump cutting apparatus wherein the cutting tooth has a removable and replaceable cutting bit. The cutting bit is removably and nonrotatably secured to a head of an elongated shank with the shank secured to a mounting block or pocket of a stump cutting tool. A support member having an indexing surface is also removably and nonrotatably secured to the head of the elongated shank. Accordingly, the support member enables indexing the cutting bit to expose and use a plurality of cutting edges located on the periphery of the cutting bit.

Abstract: A stump cutting tool for use with a stump cutting apparatus having a rotatable cutting wheel or drum having at least one cutting tool mounted to the wheel or drum. The cutting tool includes a tool holder or pocket used to secure a separate cutting tooth. The pocket or tool holder includes the least one bore extending therethrough for use in securing the cutting tool to the cutting wheel or drum.

Abstract: A nail for use with repairing a bone fracture. The nail includes a cutting tip formed of at least one facet defining a cutting edge. The facet is skewed with respect to a primary longitudinal axis extending through the nail from the proximal end to the distal end. The nail further includes at least one groove extending longitudinally on the nail from the distal end to the proximal end, the groove having a cutting edge used to increase or enlarge the entry opening as the diameter of the nail increases from the distal end to the proximal end.

Abstract: A temperature sensor used to monitor coolant and an automobile coolant system. The temperature sensor includes a one-piece housing having a sensor portion and a connector portion. A sensor assembly, including a sensor having a pair of terminals connected thereto is disposed within the housing. The sensor portion includes a sensor tip having a configuration conducive to improving thermal transfer from the coolant through the sensor tip to the sensor. A thermally conductive material may also be used to improve thermal or heat transfer to the sensor.

Abstract: An adjustable lumbar support mechanism located in a seat back of a vehicle seat for supporting the lower back of a seat occupant. The lumbar support mechanism generally includes a lumbar support member supported on a frame within the seat back. The support member includes a sheet or panel formed of a resilient material. The panel including a plurality of openings located therein. A rib extending on the rear surface of the panel helps to control and provide rigidity to the support member. A seat occupant utilizes an actuator, coupled by an adjustment cable to the support member, to adjust the curvature and thereby vary support provided by the lumbar support mechanism.
