The assembly fixtures also comprise a disc (or tab) that provides a natural appearance to the joint and allows for ease of assembly.

Abstract: The clamping band is used to clamp a connector boot within a hole in a manhole riser or other generally cylindrical structure, particularly where the depth of the hole is greater than the thickness of the manhole riser. The clamping band has a width such that a portion of the band extends beyond the hole surface. The clamping band preferably overhangs both the inner surface and outer surface of the generally cylindrical wall of the manhole riser. In one embodiment, the clamping band is used to affect a pipe-to-manhole connection.

Abstract: A stuffing box support assembly is configured to be positioned between a production pumping tree and a stuffing box of a wellhead. In use, the support assembly functions like a joint between the wellhead production tree and the stuffing box. The support assembly is configured such that it could tilt or move laterally to maintain a coaxial relationship between the stuffing box and a polished rod extending therethrough. This alignment between the stuffing box and the polished rod reduces wear and tear of the stuffing box packing.

The methods and apparatus basically comprise the steps of entering a gravel packed well and perforating the gravel pack screen and fracture packing the formation through the screen perforations. At least the last portion of the particulate is preferably coated with a consolidator that will form a proppant pack. Installing a second screen in the well to overlap the perforations in the gravel pack screen to prevent the particulate from reentering the well.

Abstract: A driven tool includes a driven part which is rotatably driven by a drive part. The driven part and the drive part are coaxially arranged one inside of the other. The drive part and the driven part are conical as viewed in a longitudinal section plane containing the axis. The driven part includes driven teeth projecting generally radially with respect to the axis and received in respective radially-open recesses formed in the drive part. Each of the driven teeth makes contact with a wall of the respective recess at first and second contact places which are respectively situated on opposite sides of a generally radial line of symmetry of the driven tooth. The contact places are operable to transmit a drive force from the drive part to the driven part in respective directions of rotation. A driving angle in the range of −5° to +45° is formed at each contact place.

The speed may be varied from 0 rpms to at least 500 rpms. A desirable range of operation is from 0 to 200 rpms. This ability to control and vary the speed of the stem greatly increases the safe operation of present kelly spinner over the prior art kelly spinners.

Abstract: A connection apparatus for an artificial model includes a resilient device and a post device. The resilient device has a hollow shaft extending upward from the fixing disk thereof to fit with a sleeve disposed outside the hollow shaft. A plurality of balls are attached to the hollow shaft and retained between the hollow shaft and the sleeve. The post device further includes a flange and an upright post. The upright post is inserted into the hollow shaft with the round top thereof passing over the balls such that the resilient device can join with the post device. Once the push lever is pushed with the slant parts thereof pressing the sleeve to slide the fixing disk forward, the annular projection section of the sleeve may slide away the balls to release the balls from the recess ring on the push rod such that the post is taken out from the hollow shaft to disengage the post device from the resilient device.

Abstract: A dielectric joint for pipes, particularly for underground pipes, comprises a male head of a first pipe which enters a mating and mutually opposite cup-shaped female head of a second pipe; a sealing insulating means is interposed between the pipes and is externally extended on the first pipe by an extent which reaches beyond the inlet edge of the female head and internally forms a tight-fitting cladding of the first and second pipes for a longitudinal extent which is at least equal to the overall length of the joint.

Abstract: A connector comprises a casing 20 with a pipe fitting bore 25 to which a pipe P is fitted; a pipe fixing component 30 which slides against the casing and fixed the pipe P when the pipe is fitted to the pipe fitting bore 25; and a seal component 40 that is mounted facing the pipe duct 26 to seal the pipe P. The pipe fixing component 30 is elastically deformed, when the pipe P is fitted, from the temporary stop position at which it is temporarily stopped in the pipe fitting bore 25, and moves to the connecting position where the pipe is fixed, it being possible to externally view whether the pipe fixing component 30 is in the connecting position. The connector requires no checker or the like to check the connection with the pipe P, thus preventing poor seals.

Abstract: The fastener includes a head with an oval-shaped base. The head is supported by a cylindrical post and includes overhanging or cantilevered portions along the major axis of the oval-shaped base. These overhanging portions are ramped and face a first seal. The head engages a slot in a panel by first being inserted therethrough and then being twisted by one quarter turn so that the edges of the slot are engaged between the first seal and the cantilevered portions. Flex tabs lock the head in place. The fastener further includes a cylindrical retainer with flexible retaining fingers which is inserted by a linear motion into an aperture in another panel, thereby engaging the panel between the retaining fingers and the second seal.
