Abstract: A tong assembly having a powered tong mounted over a backup tong is supported at its rear by a post with torque measuring means. The powered tong is supported at its front, near its throat, by one or more struts that extend downwardly to the backup tong. Such strut (s) provide support for the powered tong when the assembly is placed on a support surface for storage. The struts each have a joint with a retracted condition in which the joint is rigid when the tong is placed on a support surface, and an extended condition in which the joint allows a degree of lateral displacement when the tong assembly is applying torque to a pipe string. This maximizes the amount of torque passing through the rearward post, and therefore ensures a more accurate sensing of applied torque by the torque-measuring device.

Abstract: A threaded fastener capable of being reduced in size and weight. A pair of side wall surfaces of each of six radially outwardly projecting, torque transmitting portions lie on straight lines passing through the center line in a cross section perpendicular to the center line so as to transmit torque through the side wall surface, whereby the direction of a surface orthogonal force N applied to a force-applied point P by a wrenching tool coincides with the direction of an effective wrenching force F. This arrangement reduces an operation force required for rotating the wrenching tool and accordingly the load acting on each of the torque transmitting portions, in comparison with a conventional hexagonal head. That is, it is possible to reduce the diameter of the head portion of the threaded fastener and the size and weight of the head portion, while avoiding deformation of the side wall surfaces through which the torque is transmitted.

The other of the pairs of conveyor belts engage the opposed side faces in the upper surface section of the concrete block to expose the lower surface section thereof to be abraded by further respective surfaces abrading devices.

Abstract: A torque wrench is provided having body and a handle that is rotatably mounted to the body for adjusting the torque setting, and an axially movable sleeve operable to selectively lock the handle. The sleeve includes a rigid member and an elastomeric member, such as an O-ring, and the sleeve is configured to act against a locking ball held in a bore of the handle. The sleeve is selectively movable between two positions: (a) a locked position wherein the rigid member firmly retains the locking ball seated in one of several detents in the body, thereby preventing rotation of the handle; and (b) an unlocked position wherein the elastomeric member biases the locking ball inwardly, deflecting when the locking ball unseats from the detent to permit handle rotation. When the sleeve is in the unlocked position, the locking ball can incrementally “click” over the detents during handle rotation.

Abstract: A saw cutting pattern is dynamically established for a semiconductor dicing saw based on detection of the saw blade contacting a wafer or a portion of a wafer. The dynamic cutting pattern may terminate cuts if the saw blade no longer contacts the wafer or a portion of a wafer. Thus, irregular shaped wafers may be cut without requiring that an entire predefined cutting pattern be carried out and/or without previously mapping the shape of the wafer or portion of a wafer. A map of the wafer or a portion of a wafer may also be generated based on the detection of the saw blade contacting the wafer during a first cutting pass and may be used during a second cutting pass.
