    • A face or face insert (40) for a golf club head (20) is disclosed herein. The face (40) has an interior surface (40b) with a first thickness section (200) and a second thickness region (205). The first thickness section (200) preferably has a thickness that is at least 0.025 inch greater than the thickness of the second thickness region (205). In a most preferred embodiment, the first thickness section (200) has an X shape that is rotated around the Y axis (500) by at least 10 degrees. In another preferred embodiment, the face has a first thickness section (200), a second thickness region (205), and a central region (400) having a third thickness. The face or face insert (40) with variable thickness allows for a face or face insert (40) with less mass in a golf club head (20) that conforms to the United States Golf Association regulations.
    • 本文公开了一种用于高尔夫球杆头(20)的面部或面部插入件(40)。 面(40)具有内表面(40b),其具有第一厚度部分(200)和第二厚度区域(205)。 第一厚度部分(200)优选地具有比第二厚度区域(205)的厚度大至少0.025英寸的厚度。 在最优选的实施例中,第一厚度部分(200)具有绕Y轴(500)旋转至少10度的X形状。 在另一优选实施例中,所述面具有第一厚度部分(200),第二厚度区域(205)和具有第三厚度的中心区域(400)。 具有可变厚度的面部或面部插入物(40)允许在符合美国高尔夫球会规定的高尔夫球杆头(20)中具有较少质量的面部或面部插入物(40)。

    • The invention relates to a downhole device for incorporation into a downhole string and movement in a wellbore. The device comprises a body member, at least one roller arranged on the device to engage the inner surface of the wellbore and means to orient the device in the wellbore. The means to orient the device are provided on the or each roller. Preferably the means to orient the device comprise a projecting portion provided on the or each roller which projects radially outwardly from the body member. The projecting portion can be an eccentrically-shaped portion of the or each roller.
    • 本发明涉及一种用于结合到井下柱中的井下装置和在井眼中的运动。 该装置包括主体构件,布置在装置上的至少一个辊以接合井眼的内表面,以及将装置定向在井眼中的装置。 定位设备的方法设置在每个滚筒上。 优选地,用于定向装置的装置包括设置在该主体构件上径向向外突出的每个辊上的突出部分。 突出部分可以是每个辊的偏心形状的部分。
