Abstract: A convertible trailer for road and rail operation has four rail wheels and two road wheels. Each road wheel is within a road wheel assembly which connects to a main pivot or axle on the trailer, around which the entire assembly can rotate and thereby separating the road wheels from direct connection to the trailer. A lift, which may be motorized or hand controlled, raises and lowers the entire trailer by raising or lowering a foot which engages with the ground. When raised sufficiently and a locking mechanism disengaged, the road wheel assemblies may pivot on the pivot or axle. This pivoting allows the wheels to be locked in high position out of the way for rail operation. With the road wheels disengaged, the trailer may be lowered allowing the rail wheels to contact rails for railway operation.

Abstract: A rotary phase separator system generally includes a step-shaped rotary drum separator (RDS) and a motor assembly. The aspect ratio of the stepped drum minimizes power for both the accumulating and pumping functions. The accumulator section of the RDS has a relatively small diameter to minimize power losses within an axial length to define significant volume for accumulation. The pumping section of the RDS has a larger diameter to increase pumping head but has a shorter axial length to minimize power losses. The motor assembly drives the RDS at a low speed for separating and accumulating and a higher speed for pumping.

Abstract: A pharmaceutical composition is disclosed which comprises a solid dispersion of a pharmaceutical compound in a water soluble carrier, such as polyethylene glycol (PEG), and a crystallization inhibitor, such as polyvinylpyrrolidone or hydroxypropylmethylcellulose. The solid dispersion may optionally be encapsulated in hard gelatin capsules, compressed into a tablet, or may be granulated with a pharmaceutically acceptable granulating agent. Also disclosed are methods of making said solid dispersion and methods of treatment employing said solid dispersion.
