    摘要： A method for determining the relative permeability of an earth formation surrounding a wellbore having a longitudinal axis comprising the steps of injecting a fluid into the wellbore such that the fluid invades the earth formation, measuring at different points in time a quantity that varies in response to the radius from the wellbore axis of the fluid invasion into the earth formation, determining in response to said quantity measurements the radius from the wellbore axis of the fluid invasion into the earth formation, and determining in response to said radii determinations the relative permeability of the earth formation. A system for performing the method is also disclosed.

    摘要： Devices, and methods for non-suture end-to-end and end-to-side anastomosis of tubular tissue members employ tubular connection members having clip retaining elements comprising annular grooves or flanges in the connection members; and spring clips which comprise a ring-shaped body with separable opposed ends whereby a circular opening defined by the body can be enlarged; the opposed ends have handling elements to facilitate handling of the clips and separation of the opposed ends; specially developed instruments facilitate use of the devices and the anastomosis procedure can be completed much more rapidly than with conventional techniques and has the significant advantage of intima to intima contact at the site of anastomosis with no foreign material exposed to the lumen of the vessels being joined.

    摘要： The invention provides a light source for use with diagnostic devices such as laparoscope having a male fitting to receive a light tube connection for transmitting light within the device to an end for viewing using an eyepiece on the device. The light source has an elongate casing and an electrical storage battery contained in the casing. The battery extends longitudinally and has first and second poles at opposite ends of the battery. A tubular insulating insert is positioned inside the casing at one of the ends of the casing and adjacent the first of the poles. A bulb is located in the insert and has the center terminal of the bulb in electrical connection with the first pole. First and second contacts are insulated from one another and located by the insert with the first contact coupled to the body of the bulb and the second contact coupled to the second pole. Both the contacts project slightly inwardly within the insert whereby when the light source is pushed over the male fitting, the light source is located on the diagnostic device and the male fitting completes the electrical circuit. The bulb is then powered so that light passes through the device to the end of the device.

    摘要翻译： 本发明提供一种用于诊断装置的光源，例如腹腔镜，其具有阳配件以接收用于将装置内的光透射到使用装置上的目镜观察的端部的光管连接。 光源具有细长壳体和容纳在壳体中的蓄电池。 电池纵向延伸并且在电池的相对端具有第一和第二极。 管状绝缘插入件位于壳体内部的壳体的一端并与第一极相邻。 灯泡位于插座中，灯泡的中心端与第一极电连接。 第一和第二触点彼此绝缘并且通过插入件定位，第一触点耦合到灯泡的主体，并且第二触点耦合到第二极。 两个触点在插入件内稍微向内突出，由此当光源被推到阳配件上时，光源位于诊断装置上，并且阳配件完成电路。 然后为灯泡供电，使得光通过设备到设备的端部。
