Abstract: The present invention is a rigid, solid bodied stringed instrument having an electrical pickup embedded in at least one predetermined position within the stringed instruments solid body to pick up the actual wood tones and resonance of the rigid solid body. The electrical pickup is comprised of a piezoelectric transducer embedded between a planar brass surface and a planar ceramic surface. In the preferred embodiment, the pickup transducer is circular in shape and embedded within the stringed instrument's solid body adjacent the strings which span the body. The embedded piezoelectric transducer requires a fraction of the area required by traditional electric coil pickups. In an alternate preferred embodiment, the pickup transducer is embedded within a transducer housing. The housing is then embedded within the solid body of a stringed instrument adjacent the strings.

Abstract: Induction hardening of heat treated gear teeth which includes the steps of rough and finish cutting the gear teeth, or alternatively cutting the gear teeth to their final configuration utilizing a one cut method, carburizing the gear and in particular, the gear teeth, slow cooling, or alternatively drawing back the gear so the gear teeth are not hard, and induction hardening the gear teeth heating only the surface of the gear teeth. This results in improved strength for the gear teeth as a result of increased residual compressive stresses therein. Induction heating of only the surface of the gear teeth results in an relatively low case depth in the root of the gear teeth.

Abstract: A disc brake rotor for motor vehicles, having a dual web structural support for connecting a pair of brake discs to a rotor hub that is positioned centrally within the brake rotor without lateral offset. The dual web structural support creates a fanning effect that draws a flow of cooling air between the brake discs. Air flow is further promoted by providing connective ribs located between the brake discs with a shape that produces a pressure drop across the discs and thereby draws cooling air between the discs.

Abstract: A container for shipping or transporting one or more young plants or seedlings, especially through the mail. The container has an open top and is made preferably of a thin, very light-weight, thermoformed plastic. The container is divided into two sections: a bottom section for receiving the plant pot and/or root ball and an upper section for receiving the stem and leaves. A cover is connected by a living hinge to the bottom section. The cover acts to hold the plant pot and/or root ball in place and to reduce evaporation of moisture from the root region of the plant. The container is provided with a wall separating the upper and bottom sections. The wall is supplied with a smoothly contoured notch that permits the plant stem to pass from the bottom section to the upper section, and the cover or lid utilizes a "V"-shaped projecting member to gently direct the plant's leaves and stem into the contoured notch. A combination of engaging recesses and projections form a closure system that holds the lid in place.

Abstract: A bushing for a vehicle suspension system has a hollow cylindrical sleeve and a hollow cylindrical jacket, with first and second elastomeric members compressively preloaded into an annular space between the sleeve and the jacket. The elastomeric members, which are complementary in filling the annular space, are selected from different materials possessing different spring rates. The elastomeric members are preferably semicircular radial sections of an annulus. When the bushing is aligned in the vehicle suspension, the bushing exhibits at least one diameter where the bushing effectively has a first spring rate when the bushing is acted on by a force in a first radial direction and exhibits a different spring rate when the bushing is acted upon by a force in a second radial direction which is one hundred eighty degrees opposed to the first radial direction.

Abstract: A transition section for a railway hopper car carries structural loads from an endmost hopper of the hopper car into the hopper car end structure, whence the loads are transferred to and from other cars via the coupler, and into the rail car truck. The sidewall of the endmost hopper has an extension that mates smoothly with a curved flange extending from the hopper end structure, such that the transition varies smoothly in section.

Abstract: A method for sensing the concentrations of diatomic gases in a flow chamber is achieved by focusing an incident beam of light from a monochromatic light source on a point internal to the flow chamber through a transparent window. The incident excites molecules of the diatomic gas, resulting in emission of scattered light of particular characteristic frequency for each species of diatomic gas, due to the Raman principle. By collecting the scattered light beam from the flow chamber through the window and analyzing the intensity of the collected scattered beam at these characteristic frequencies, the relative concentrations of each of the diatomic gases may be determined.
