摘要： An automotive exhaust catalyst includes a support, which is less likely to adsorb SO.sub.x contained in exhaust gases thereon, an NO.sub.x storage compound loaded on the support, and a noble metal element loaded on the support. The support is an alumina support with a Ti--Zr composite oxide loaded thereon, or is formed of a Ti--Zr or Ti--Zr--Y composite oxide. The composite oxide inhibits the NO.sub.x storage compound, which is selected from alkali metals, alkaline-earth metals and rare-earth elements, from being poisoned by sulfur, and enhances the thermal resistance of the support. Thus, the automotive exhaust catalyst can effectively purify NO.sub.x contained in lean-side exhaust gases, even after it is subjected to a thermal durability test.
摘要翻译：汽车尾气催化剂包括不太可能吸附其中排出的SO x的载体，负载在载体上的NOx储存化合物和负载在载体上的贵金属元素。载体是负载有Ti-Zr复合氧化物的氧化铝载体，或由Ti-Zr或Ti-Zr-Y复合氧化物形成。复合氧化物抑制从碱金属，碱土金属和稀土元素中选择的NOx储存化合物被硫中毒，提高了载体的耐热性。因此，即使进行耐热试验，汽车尾气催化剂也能够有效地净化稀薄侧排气中所含的NOx。

摘要： A large-scale cleaning vehicle, for operation with a forklift, includes rotation brushes for sweeping debris toward a center of said cleaning vehicle, a sweeping brush for sweeping the debris into a debris collection box and a fan for pulling said debris into said debris collection box without the need for a motor in the cleaning vehicle. Each of the rotation brushes, the sweeping brush, and the fan are rotatably connected to a rear wheel of the cleaning vehicle such that when the cleaning vehicle is moved, the brushes and fan are rotated. The cleaning vehicle further includes a vertical adjustment for the rotation brushes to lift them when they are not needed, a lateral adjustment for the rotation brushes to adjust a width of sweeping, an audible warning for pedestrians, a water sprinkler system to aid in the cleaning process, and a large-scale trash removal brush mounted in front of the cleaning vehicle to push large-scale trash.

摘要： A device for removing an adhered foreign substance, such as chewing gum, from surfaces employs a reciprocating scraper that separates the substance from the surface to be cleaned. A liquid, such as cleaning solution or solvent, is optionally discharged in the vicinity of the end of the scraper to augment the separation. A vacuum device draws air and loosened matter into an opening in the nozzle and traps it in a container. Optionally, the vacuum device is attached to a nozzle movable away from and toward the scraper by pushing a handle. When the nozzle moves toward the scraper, it activates the vacuum device.
