Abstract: A device for use in removing a conveyance member from a material includes a displacement element (12, 1012) and a self-propelling driving element. The displacement element (12, 1012) is for being placed at least partly around a conveyance member (16) and for displacing material as the displacement element (12, 1012) is advanced along a conveyance member (16). The driving element is coupled to and movable with the displacement element (12, 1012) to advance the displacement element along a conveyance member (16).

Abstract: The disclosure illustrates a dual driver for surgical reamers in which either of a crossbridge and crossbar style reamers are axially inserted in the distal end of a central shaft for the reamer driver. A pair of L shaped grips are adapted to connect and disconnect the different style of reamers by the movement of an external sleeve biased towards the connection position. Movement of the sleeve away from the distal end allows an internal plunger to cam the grips to an open position and urge the appropriate reamer from the tool driver directly in an axial direction.

Abstract: A hand-held power tool for driving a working tool (1) includes a drive belt (3), first and second arms (5a, 5b) longitudinally displaceable relative to each other and carrying respective deflection rollers (6) of the drive belt (3), a belt tensioning device (4) located between the first and second arms (5a, 5b) and including a spring (8) preloaded against the first arm (5a), and a displaceable pressure piston (9) located between the spring (8) and the second arm (56).

Abstract: A panel pushing assembly (10) for a slide rail system having a first and second wall (12, 14) includes an elongated member (16) having a bottom end (18) and a top end (20), and a guide (40) disposed about the elongated member (16). The guide (40) guides slidable movement along the elongated member (16) and includes a collar (42) engaging the walls (12, 14) of the elongated member (16) and a catch (44) extending laterally from the collar (42) to engage the second wall (14), which is the stationary wall. The collar (42) includes a plurality of side-plates (46) and the catch (44) includes a hook portion (70) extending downwardly along the outside of the second wall (14) for preventing lateral movement of said elongated member (16) relative to the second wall (14).

Abstract: A post driving apparatus includes a chassis having a longitudinal axis and a frame carried by the chassis. The frame includes an upper support member having an axis of elongation substantially perpendicular to the longitudinal axis of the chassis. A post magazine is indexingly supported by the frame and, a post driving assembly is suspended from a portion of the upper support member for reversible travel therealong so as to laterally position the post driving assembly from the chassis. The post driving assembly includes a post driver adapted to retain a post supplied from the post magazine, the post driver adapted to continuously drive such post.

Abstract: Apparatus for remote handling operations in which a tool carrier is provided with elongate resilient members which permit transverse or lateral displacement of the tool carrier to thereby cater for misalignment between the tool carrier and an object to be engaged by a tool mounted on the tool carrier. During such displacement the resilient members maintain the axis of the tool parallel to the axis of the remainder of the apparatus.

Abstract: A sheet pile driver and more particularly a driver which is supported from a single wall of already driven sheet piles for stabbing and driving subsequent sheet piles progressively into final position and then moving progressively onto the newly driven sheet piles with the driver being supported solely from the single wall of sheet piles and movable in either direction thereon. This invention also relates to a method of constructing a continuous steel sheet pile wall by the use of sheet piles with a driver riding on partially installed sheet piles and capable of moving back and forth the entire length of the partially installed wall and being a self-stabbing unit, grade driving unit or extractor to enable the construction of a sheet pile wall with reduction in equipment required and an increase in production rates.

Abstract: Conductor guides for use in drilling wells in an offshore body of water wherein the wells are positioned in close proximity one to the other. A first clamping member is removably attached to a well which includes a conductor or well head protruding therefrom. A conductor guide is spaced a predetermined distance from the clamping by means of a connecting beam that extends therebetween. The connecting beam is adjusted to properly position the conductor guide on the ocean floor at a fixed distance and directional relationship with the first conductor.

Abstract: A continuously slowly moving machine automatically inserts rigid elongated members in the ground at regular intervals along the perimeter of a large field to facilitate anchoring a taut textile net placed over seedling grass. Several thousand of the members must be inserted around the perimeter of a typical turf-growing plot at a spacing of a few feet apart. Ground wheels of a moving frame generate movement of a carriage which travels horizontally on the moving frame rearwardly and forwardly. The carriage supports the inserting mechanism for the members which includes a single inserting upright cylinder and a connected coordinated delivery plunger for each member advancing each member to a ready vertical position beneath the rod of the cylinder. When the carriage is at the rear of its travel relative to the moving frame substantially at zero ground speed, a member is inserted in the soil by the rod of the cylinder accompanied by simultaneous retraction of the delivery plunger.

Abstract: An apparatus for driving piles into the sea-bottom for the support of a substructure resting on the sea-bottom of a working island to be installed comprises a plurality of support constructions attached to a column. Each support construction is provided with guide passage openings for the piles and the followers. The uppermost support construction consists of an arm which extends transversely of the column, and two semi-circular claw segments secured to the free end of the arm. One of the claw segments is pivotally mounted so that the claw segments can be brought into a closed position in which they define a guide passage opening for the pile or follower.
