摘要： An ink jet printer includes an ink jet printhead having a drop generator and an ink drop charging and catching assembly. An elastomeric seal mounted on a lever arm about a pivot remote from the charging and catching assembly seals the ink drop generator and charging and catching assembly when the ink jet printer is not in use.

摘要： A method for the production of bitumen from a subterranean reservoir having a zone of increased effective permeability therein. In particular, a first well is in fluid communication with the zone of increased effective permeability at a first level in the reservoir. Fluid communication is established between a second well and the zone of increased effective permeability at a second level above the first level in the reservoir. In-situ combustion is initiated in the reservoir proximate the second well. Combustion sustaining fluid is injected through the second well into the zone of increased effective permeability so that bitumens in the reservoir are mobilized by the in-situ combustion and flow downward through the reservoir towards the first well, through which they are recovered. By using this method, a stable in-situ combustion process is established which avoids fingering and channelling and accompanying early oxygen breakthrough, consequently improving the efficiency of bitumen production from the reservoir.
摘要翻译：一种用于从其中具有增加的有效渗透率的区域的地下储层生产沥青的方法。特别地，第一井与储层中第一级增加的有效渗透率的区域流体连通。在第二井和在储层中高于第一水平的第二水平的增加的有效渗透率的区域之间建立流体连通。在靠近第二井的储层中开始原位燃烧。燃烧持续流体通过第二井注入到增加的有效渗透率的区域中，使得储层中的沥青通过原位燃烧而动员，并向下流动通过储存器朝向第一井，通过它们被回收。通过使用这种方法，建立了稳定的原位燃烧过程，避免了指法和引导，并伴随着早期的氧气穿透，从而提高了储层的沥青生产效率。
