摘要： An improved process and apparatus for recovering hydrocarbons from an air-hydrocarbon vapor mixture such as the mixture of air and vaporized light hydrocarbon compounds expelled as a result of loading gasoline or the like into storage tanks and tank trucks. The air-hydrocarbon vapor mixture is caused to flow through a bed of solid adsorbent whereby the hydrocarbons are removed from the mixture and a residue gas stream comprised of substantially hydrocarbon-free air is produced. The substantially hydrocarbon-free air is vented to the atmosphere and a second bed of solid adsorbent having hydrocarbons adsorbed thereon is subjected to conditions which cause desorption of the hydrocarbons and thereby regeneration of the bed. The flow pattern of the inlet air-hydrocarbon vapor mixture and the bed of solid adsorbed being regenerated are periodically changed so that when the bed through which the inlet air-hydrocarbon mixture is flowing becomes loaded with adsorbed hydrocarbons, the inlet air-hydrocarbon mixture is caused to flow through the bed which has just been regenerated. The regeneration of the beds is accomplished by evacuating the beds with vacuum pumping whereby a major portion of the hydrocarbons are desorbed therefrom, subsequently introducing a small quantity of heated hydrocarbon-free air into the beds whereby additional hydrocarbons are stripped therefrom and then subjecting the bed to further evacuation by ejector jet pumping while continuing to evacuate the bed by vacuum pumping whereby yet additional hydrocarbons are desorbed therefrom. The air-hydrocarbon vapor mixture produced in the regeneration of the beds is contacted with a liquid absorbent whereby a major portion of the hydrocarbons are absorbed therefrom and recovered. Apparatus for carrying out the process of the invention is also provided.
摘要翻译：一种改进的方法和装置，用于从空气 - 烃蒸气混合物中回收碳氢化合物，例如由于将汽油等装载到储罐和油罐车中而排出的空气和蒸发的轻烃化合物的混合物。使空气 - 烃蒸气混合物流过固体吸附剂床，由此从混合物中除去烃，并产生由基本上无烃的空气组成的残余气流。将基本上无烃的空气排放到大气中，并且吸附有烃的固体吸附剂的第二床受到使烃解吸并由此再生的条件。周期性地改变入口空气 - 烃蒸气混合物和被吸附的固体床的流动模式，使得当入口空气 - 烃混合物流过的床装载吸附的烃时，入口空气 - 烃混合物是使其流过刚刚再生的床。床的再生是通过真空泵抽抽床来实现的，其中主要部分的烃从其中脱附，随后将少量加热的无烃空气引入床中，由此从中除去另外的烃，然后使床以通过喷射器喷射泵进一步抽真空，同时通过真空抽吸继续抽空床，由此另外的烃从其中解吸。在床的再生中产生的空气 - 烃蒸汽混合物与液体吸收剂接触，由此主要部分的烃被吸收并回收。还提供了用于实施本发明的方法的设备。

摘要： The second stage (10) of a fail-fixed flow-control servovalve has a five-lobed valve spool (12) slidably mounted in a body bore (19). At null, the end lobes (41,45) are substantially zero-lapped with respect to supply pressure slots (22,26), the middle lobe (43) is substantially zero-lapped with respect to a pair of return slots (23,24), and the intermediate control lobes (42,45) are both symmetrically underlapped with respect to their associated control slots (29,30). Stops (34,35) limit movement of the spool in either axial direction. When the spool is at null or in either hard-over position, deliberate flow with respect to the control slots is blocked, and relative leakage flows are controlled. Such leakage flows may be balanced such that there is substantially-zero net leakage flow with respect to each control slots. Alternatively, such leakage flows may be deliberately mismatched to provide for desired net leakage flows with respect to control slots.

摘要： A conveyor assembly having a first, generally, horizontal, endless belt conveyor and a second, generally horizontal, endless belt conveyor extending perpendicular to the first conveyor and with its trailing end overlapped with the leading end of the first conveyor to carry articles away from the first conveyor. Each conveyor has several laterally spaced belts. Where the conveyors overlap their belts are interleaved to transfer articles properly from the first conveyor onto the second conveyor. The second conveyor has a top piece just below the upper course of travel for its belt with an opening having round-tipped, tapered teeth at the front to prevent the strings or the like on a laundry article being conveyed from getting tangled in the drive roller at the leading end of this conveyor.
