A book (800) designed to allow children or other people with limited motor skills to be able to easily turn the pages within the book. The book comprises a front cover (15), a back cover (16), and one or more pages. Each page has a graspable tab located on one of its edges, which extends past the tabs that are located on subsequent pages. The tabs can be in a variety of shapes.
摘要:
Methods and apparatus are provided for obtaining a secure mechanical connection and a pressure-tight seal in the overlapping area of two telescoping tubular bodies (26 and 27). The two bodies, including the overlapping area, are radially expanded to increase the inside diameter of the bodies. The expansion forces an annular seal (28) in the overlapping area into a pressure-sealing engagement between the bodies. A string of pipe assembled from joints secured to each other by telescoping, threadedly engaged expanded pin (26) and box (27) connections may be radially expanded into a surrounding well bore to provide a cased well having an internal diameter greater than the original internal diameter of the pipe string. The annular seal in the connection comprises an annular elastomeric seal ring (29) and an annular Teflon spacer ring (30). Radial expansion of the connection causes axial contraction of the groove (31), which acts with the spacer ring to expand the seal ring radially to seal the annular space created between the expanded pin (26) and box (27).

摘要:
A switch valve (10) is provided with an upper body (14) having a plurality of outlet ports (20A, 20B and 20C) and lower body housing (16) with inlet port (18). The switch valve (10) includes a ball member (22) which is rotatable within the switch valve body (12) for selective fluid communication between the inlet port (18) and the selected one of the plurality of outlet ports (20A, 20B or 20C). The ball (22) is rotated by a stem (28), which may be powered by an actuator unit (30). The upper body (14) includes a substantially dome-shaped seating surface (40) for sealing engagement with the outer surface (38) of the ball (22). The biasing member (48) biases the ball (22) radially in a direction opposite the ball inlet port (24) to obtain the desired sealing engagement. The biasing member (48) is preferably a Belleville spring (48) having a single wrap design.
