摘要： An improved mechanical face seal is provided which includes a pair of relatively rotatable seal rings having opposing seal faces. At least one of the seal faces includes a reverse trapezoidal face pattern having a sine wave depth profile wherein individual face features are circumferentially spaced over the seal face. The reverse trapezoidal face pattern serves to generate a hydrodynamic lift which provides a stable separation of the seal faces that permits formation of a fluid film between the seal faces. The individual trapezoidal grooves have a sinusoidal or similarly shaped depth profile wherein the trapezoid shape is arranged with the narrower edge communicating with the high pressure side of the seal, and the wider edge forms a circumferential dam region towards the low pressure side of the seal. Alternatively, the reverse trapezoidal face pattern may also be provided as a primary face pattern on a dry gas seal in combination with a secondary face pattern wherein the faces operate with a controlled gap under normal pressure conditions as well as when the pressure direction across the seal face is reversed.

摘要： An improved mechanical face seal is provided which includes a pair of relatively rotatable seal rings having opposing seal faces. At least one of the seal faces (72) includes a reverse trapezoidal face pattern (75) having a sine wave depth profile wherein individual face features are circumferentially spaced over the seal face (72). The reverse trapezoidal face pattern (75) serves to generate a hydrodynamic lift which provides a stable separation of the seal faces that permits formation of a fluid film between the seal faces. The individual trapezoidal grooves (76) have a sinusoidal or similarly shaped depth profile wherein the trapezoid shape is arranged with the narrower edge (78) communicating with the high pressure side of the seal, and the wider edge (79) forms a circumferential dam region (81) towards the low pressure side of the seal. Alternatively, the reverse trapezoidal face pattern may also be provided as a primary face pattern on a dry gas seal in combination with a secondary face pattern wherein the faces operate with a controlled gap under normal pressure conditions as well as when the pressure direction across the seal face is reversed.

摘要： An inflatable kite comprises two inflatable bladders 2, 3 attached to the leading edge of the upper 5 and lower 6 skins. The bladders form an air inlet 1 for the kite. Inflatable ribs (8 fig 4) are placed between the two bladders to provide bracing for the structure. The bladders may be arranged in concentric or non concentric circles according to the desired aerodynamic profile (fig 2, 3).

摘要： An evaluation of an external course may be based on course-to-requirement mappings that have been previously established for the target institution. As a result of the evaluation, the external course may be mapped to a particular program requirement for a particular student, which allows the external course to fulfill the particular program requirement at the institution for the particular student. The course evaluation may be automatic or may be performed by a human evaluator. Course-to-requirement mappings may be globally-established, and applicable to all students and applicants of the target institution, or may be applicant-specific, and only applicable to the student for which the mapping was established. Information about both globally-established and applicant-specific course-to-requirement mappings that have been previously established for the institution may be used to evaluate an external course for a particular student.
摘要翻译：外部课程的评估可以基于以前为目标机构确定的课程要求映射。作为评估的结果，外部课程可以映射到特定学生的特定课程要求，这允许外部课程在特定学生的机构满足特定的课程要求。课程评估可以是自动的，也可以由人类评价者执行。课程到要求的映射可能是全球建立的，适用于目标机构的所有学生和申请人，或者可能是申请人特定的，并且仅适用于映射建立的学生。关于以前为该机构确立的全球确定和申请人特定课程到要求的映射的信息可用于评估特定学生的外部课程。
