摘要： An energy conserving lighting system wherein a plurality of fluorescent lamps (L1', L2') are powered by a poorly regulated voltage supply which provides a decreasing supply voltage with increasing arc current so as to generally match the volt-ampere characteristics of the lamps. A transistor ballast and control circuit connected in the arc current path controls the arc current, and hence the light output, in accordance with the total ambient light, i.e., the light produced by the lamps together with whatever further light, is produced by other sources such as daylight. In another embodiment, a transistor ballast is utilized in combination with an inductive ballast (1001). The transistor ballast provides current control over a wide dynamic range up to a design current maximum at which maximum the transistor (60''') is saturated and the inductive ballast takes over the current limiting function. An operational amplifier (116) is preferably connected in the base biasing circuit of the control transistor of the transistor ballast. In an embodiment wherein two sets of lamps with separate inductive ballasts (100', 142) are provided, the arc currents for the two ballasts are scaled or matched to provide the desired light output.

摘要： A method for separating acid and sugars obtained from liquids resulting from the acid hydrolysis of a material containing at least one of cellulose and hemicellulose is disclosed, comprising adding the liquids to a separation unit comprising a bed of anionic exchange or exclusion chromatographic material whereby the acid is adsorbed onto the chromatographic material, thereby producing a series of first fractions comprising sugar solutions and a later series of fractions comprising acid solutions. A process for an economical, energy efficient production of ethanol from municipal solid waste and other cellulosic feedstocks is also disclosed.

摘要： A method of processing waste is disclosed wherein the municipal solid waste is segregated and processed to recover reusable rubber, metal, plastic, glass and the remaining organic portion of the waste stream is used to make ethanol and other chemicals. One process utilizes a pretreatment step with dilute sulfuric acid to reduce the heavy metal content of the cellulosic component of the municipal solid waste which can inhibit the fermentation of the sugars obtained from such waste. In another, the heavy metal content of the cellulosic component of municipal solid waste is removed via an ionic exchange process, after hydrolysis with sulfuric acid. A process for an economical, energy efficient production of ethanol from municipal solid waste is also disclosed.
摘要翻译：公开了一种处理废物的方法，其中城市固体废物被分离和加工以回收可重复使用的橡胶，金属，塑料，玻璃，并且废物流的剩余有机部分用于制备乙醇和其它化学品。一种方法是利用稀硫酸进行预处理步骤来降低城市固体废物的纤维素成分的重金属含量，这可以抑制由这种废物获得的糖的发酵。另一方面，城市固体废物的纤维素成分的重金属含量通过离子交换法在用硫酸水解后除去。还公开了一种从城市固体废物中经济，高效地生产乙醇的方法。
