摘要： A process and a product formed thereby for the recovery of chromium values from aqueous solutions (e.g., waste liquors) comprises contacting an acidic solution containing sulfate ion and trivalent chromium ion with at least about 4 molar equivalents of MgO or Mg(OH).sub.2 per 3 molar equivalents of trivalent chromium in addition to the amount required to neutralize the free acid to a pH of about 4 to form an amorphous, dense solid, grainy, easily settleable, trivalent chromium-containing precipitate in an alkaline solution according to the equation: 3Cr.sub.2 (SO.sub.4) + 8 MgO .fwdarw.Cr.sub.2 (OH).sub.4 SO.sub.4 .multidot. 4Cr(OH).sub.3 .multidot. 4H.sub.2 O + 8 MgSO.sub.4. The trivalent chromium-containing product can be readily separated from the water and is a useful source of chromium for subsequent processing. The water remaining after separation of the precipitate contains less than 0.5 mg/l chromium.

摘要： A catalytic conversion unit treats emissions emanating from a cooking event. The unit comprises a housing to contain the other components that connects either directly or through the use of ancillary components to the oven cavity of a residential range, or oven. Contained within the housing are an electric heating element and a catalyst unit. The housing may connect to additional components to complete the venting of the exhaust to the atmosphere. The electric heating element is arranged so that infrared radiation from the hot surface of the element is visible by the inlet face of the catalyst. The power output of the heater is sized so that the catalyst reaches a minimum operating temperature to initiate the catalytic reaction in advance of the temperature increase in the air coming from the cavity.

摘要： A system and method for non-destructive testing of a monolith catalyst element includes a flat surface on which a monolith catalyst can be placed and a portion of the catalyst sealed against a piping arrangement located above and below the flat surface. A test fluid passes between the piping and therefore through the portion of the sealed catalyst section. Ports located in the piping allow for sampling of the fluid before and after the catalyst section. The catalyst element may then be repositioned on the flat surface for testing of a second portion of the element.

摘要： The ATRAS (Spanish word for back or behind) Spare Tire Mounting Kit is designed specifically for installation on the rear end of Ford Granada and Mercury Monarch automobiles, years 1975 to 1979, to include both two and four-door models. The primary purpose of the ATRAS Spare Tire Mounting Kit is to increase the usuable interior trunk capacity by as much as 31 percent. This is accomplished by removing the spare tire from the trunk interior and mounting it on the rear of the car.The ATRAS Spare Tire Mounting Kit is designed for utility, convenience and appearance.Its unique feature is the integral steel mounting device which is bolted to the rear of the car body in such a manner as to encircle the original gas-filler portal, serving as the protective housing for the 8" curved metal gas-filler extension tube as well as the wheel hub upon which the spare tire is mounted. A studded metal cinch with an ATRAS anti-theft locking device is specifically designed, as are the telescoping bumper extension mountings which conform to all existing safety standards.
摘要翻译： ATRAS（西班牙语后面或后面）备用轮胎安装套件专为安装在Ford Granada和Mercury Monarch汽车的后端而设计，1975年至1979年，包括两门和四门车型。 ATRAS Spare Tire安装套件的主要目的是将可用的内部干线容量提高多达31％。这是通过将备用轮胎从行李箱内部拆下并将其安装在汽车后部来实现的。 ATRAS Spare Tire安装套件专为实用，便利和外观而设计。其独特的特征是一体式钢制安装装置，其以围绕原始气体填充器入口的方式螺栓连接到车体的后部，用作8“弯曲金属气体填充器延长管的保护壳体以及安装备用轮胎的轮毂。具有ATRAS防盗锁定装置的镶嵌金属系带是专门设计的，伸缩式保险杠延伸装置也符合所有现有的安全标准。
