摘要： Titanium dioxide pigment prepared by the high pressure (e.g., 10-200 PSIG) oxidation of TiCl.sub.4 vapor is improved with respect to carbon black undertone, specific surface area, and gloss properties by the addition of a nucleant consisting essentially of a cesium substance which is present in the amount of about 8-2,000 parts per million, based on the weight of the TiO.sub.2. The foregoing process is also used wherein the residence time of the reactants in the mixing zone of the reactor is about 1-16 milliseconds.

摘要： A seat leveling device is disclosed for stabilizing the seat of a vehicle when moving over uneven terrain. The seat leveling device comprises a vehicle and a seat secured to the vehicle. The vehicle is typically a hillside lift used to carry passengers and goods back and forth between a hilltop and a bottom of the hill. The seat leveling device further comprises a detection component and a drive component, wherein the detection component is in communication with the drive component. Specifically, the detection component detects a position of the seat and transmits a signal to the drive component when the seat becomes unleveled. In one embodiment, the detection component is a pendulum and the drive component is a hydraulic pump and cylinder. The pendulum is secured to the seat, and swings when the seat becomes unleveled, which activates the hydraulic pump and cylinder to level the seat.
