摘要： This disclosure relates to process for producing titanium dioxide (TiO2) pigments, comprising the following steps: a) oxidizing a mixture of titanium tetrahalide and a rutile forming agent, such as aluminum halide, present in the vapor phase and in the presence of a nucleant to form a gaseous suspension comprising titanium dioxide particles; b) passing the gaseous suspension to a cooling conduit; c) introducing scouring material into the cooling conduit; wherein the particles of the scouring material have a diameter in the range of about 0.25 mm to about 12.7 mm; d) separating the vapor phase to form a powder comprising the titanium dioxide particles and the scouring material; and e) simultaneously subjecting the powder to substantially uniform heating at a temperature of about 300° C. to about 600° C. and reducing the size of the titanium dioxide particles and the particles of the scouring material in the powder to a mean particle size of about 50 nm to about 1000 nm, whereby the titanium dioxide pigment has a chloride content of less than about 500 ppm. The so treated powder may have a residual free chlorine content of less than about 1 ppm.

摘要： A hybrid low power/low speed vehicle that operates both with battery power and IC engine power. An electronic controls unit monitors the charge on the battery. For vehicles used both indoors and outdoors, the control unit warns the user of low charge. If outdoors, the user can command the control unit to start the IC engine and continue operating the vehicle. The IC engine, while powering the wheels of the vehicle, will also charge the battery. When the battery is fully charged, the control unit will prevent the battery from overcharging. The user can shutoff the IC engine at any time and the control unit will switch to battery operation of the vehicle. For vehicles used exclusively outdoors, the control unit will automatically start the IC engine when the battery charge has fallen below a predetermined level. Similarly, once the battery is fully charged, it will automatically stop the engine and switch to battery power for running the vehicle.
摘要翻译：混合低功率/低速车辆，既可以兼容电池电量又可用于IC发动机功率。电子控制单元监视电池的充电。对于在室内和室外使用的车辆，控制单元向用户发出低电荷警告。如果在户外，用户可以命令控制单元启动IC引擎并继续操作车辆。 IC引擎在为车辆的车轮供电时也将为电池充电。当电池充满电时，控制单元将防止电池过度充电。用户可以随时关闭IC引擎，并且控制单元将切换到车辆的电池操作。对于专门用于户外的车辆，当电池电量低于预定水平时，控制单元将自动启动IC引擎。类似地，一旦电池完全充电，它将自动停止发动机并切换到用于运行车辆的电池电力。
