Abstract: A cement head and casing assembly includes a cement head body having a cement passage defined therethrough.  The body is mounted on the well casing and has a lower portion extending down into the casing, with an upper portion extending a relatively short distance above an upper end of the casing.  A cement plug is closely received within a bore of the casing below the upper end thereof.  The cement plug is releasably connected to the lower portion of the cement head body so that the plug is suspended from the lower por-tion of the cement head body within the casing.  The cement plug has a plug passage defined therethrough which is com-municated with a cement passage in the cement head body so that cement can be pumped down through the cement head body and the cement plug into the casing.  The passage through the cement plug can be closed and the cement plug can be released from the cement plug body after the cement has been pumped into the casing.

IPC: E05F11/48
Filed: 1990-02-05
Abstract: ABSTRACT OF THE DISCLOSURE    An improved driver unit of a Bowden-cable-operated window lift mechanism is provided herein in which the actual window pane-holder can adjust itself automatically in at least three directions. This is accomplished by means of a guide rail along which a sliding, carriage with a projecting pin moves.  The guide rail, in conjunction with a sliding block, supports the actual window pane-holder. The sliding block has a curved outer contour and the window pane holder sits on the sliding block with a cylindrical guide socket which engages around and is larger than the sliding block. Since the pin is also larger than the sliding block, the window pane holder can move on the pin not only perpendicularly but also transversely to the guide rail. By virtue of the spherical outer contour of the sliding block, the window pane holder can also tilt on the sliding block in a direction perpendicular to the guide rail.
