Abstract: A railroad crosstie made from recycled rubber and its method for making is disclosed. The rubber crosstie has an expected life of between 30 to 60 years and can be made primarily of rubber crumbs obtained from stockpiles of discarded rubber tires.

Abstract: A method for the manufacture of a railroad crosstie (90) from recycled rubber is disclosed. The rubber crosstie (90) has an expected life of between 30 to 60 years and can be made primarily of rubber crumbs obtained from stockpiles of discarded rubber tires. A feature of the invention is to produce a crosstie (90) having at least one longitudinal side incorporating a plurality of indentations for more effective engagement upon installation into a gravel bed to avoid slippage.

Abstract: An x-ray tube and x-ray system including an anode assembly having a shaft with a first end and a second end, a target connected to the first end of the shaft, and a rotor connected to the second end of the shaft. The anode assembly further having spaced-apart bearings rotatably supporting the shaft. The shaft, target, and rotor positioned relative to each other such that the center of gravity of the combination of the shaft, the target, and the rotor is positioned between the bearings. Additionally, the target and rotor may be flexibly interconnected allowing the beneficial use of gyroscopic effects.

Abstract: Particle compositions are described comprising certain metal halides in combination with a strengthening agent. The addition of the strengthening agent to a metal halide particle increases the particle's strength thereby reducing breakage on impact and during handling. When used as a vaporizable metal halide fill in discharge lamps, the particle strength is increased without significantly altering the spectral and electrical characteristics of the lamp. Methods of making the particles and arc tube containing the particles are also disclosed.
