    • An automated system and method for applying thermoplastic adhesives to work pieces from a roll of adhesive segments applied to an adhesive segment-laden carrier release tape. The adhesive segment is applied from the adhesive segment-laden carrier release tape onto a work piece by the use of an automatically actuated applicator head that contacts the surface of the adhesive segment-laden carrier release tape opposite the adhesive segment thereon to push the adhesive segment against the work piece to apply the adhesive segment to the work piece. The applicator head may include one or more sharp projections thereon that pierce through the carrier release tape, but not through the adhesive segment thereon, as the head presses the carrier release tape and adhesive segment against the work piece to facilitate assured release of the adhesive segment from the carrier release tape and application of the adhesive segment to a work piece by the applicator head. Alternatively the adhesive segment carrier release tape may be pre-perforated underneath each adhesive segment thereon.
    • 一种自动化系统和方法,用于将热塑性粘合剂从施加到粘合剂段的载体释放带上的粘合剂段的辊施加到工件上。 粘合剂段通过使用自动致动的施加器头从粘合剂段载体释放带施加到工件上,该施加头接触与其上的粘合剂段相对的粘合剂段载体释放带的表面,以推动粘合剂段 抵靠工件将粘合剂段施加到工件上。 当头部将载体释放带和粘合剂部分压靠在工件上时,涂抹器头可以包括穿过载体剥离带而不穿过其上的粘合剂段的一个或多个尖锐的突起,以便有利地释放粘合剂段 从载体剥离胶带和通过涂抹头将粘合剂段施加到工件上。 或者,粘合剂段载体释放带可以在其上的每个粘合剂段的下方预穿孔。

    • A hydrocarbon-based or ester-based drilling fluid or mud is described wherein the drilling fluid contains cesium phosphate. The hydrocarbon-based or ester-based drilling fluid or mud can have, for example, an external phase that contains hydrocarbon fluid and an internal phase that contains cesium phosphate. The hydrocarbon-based drilling fluid or mud can further contain at least one emulsifier or surfactant, and optionally other ingredients. The present invention can permit hydrocarbon-based drilling fluids to be essentially solids-free and may be used without corrosion and/or formation damage problems, for example, due to the use of the cesium phosphate in an internal phase of the hydrocarbon-based or ester-based drilling fluid. The present invention also relates to hydrocarbon-based or ester-based fluids for completion, workover, suspension and packer operations which contain cesium phosphate.
    • 描述了一种烃基或酯基钻井液或泥浆,其中钻井液含有磷酸铯。 烃基或酯基钻井液或泥浆可以具有例如含有烃流体和含有磷酸铯的内相的外部相。 烃类钻井液或泥浆还可以含有至少一种乳化剂或表面活性剂,以及任选的其它成分。 本发明可以允许基于烃的钻井液基本上是无固体的,并且可以不使用腐蚀和/或地层损伤问题来使用,例如,由于在烃基的内相中使用磷酸铯或 酯基钻井液。 本发明还涉及含有磷酸铯的用于完成,修井,悬浮和封隔器操作的烃基或酯基流体。
