A hammer for installing a gasket into a joint between two pipes, the hammer comprising two opposed substantially rectangular, non-square strike surfaces which are rotationally offset from one another by 90 degrees such that an appropriate substantially rectangular, non-square strike surface may be selected by the user and applied to a gasket by simply rotating the hammer in the user's hands without requiring the user to relocate around the gasket.

A flexible coupling includes a flexible diaphragm body having a first end and a second end. A member is fixed to the first end of the flexible diaphragm body. A splined member is fixed to the second end of the flexible diaphragm body. The splined member is configured to shift relative to a rotatable member rotatably fixed thereto in response to axial displacement of rotatable members interconnected by the flexible coupling. The ratio of inner diameter to the outer diameter is selected to allow for packaging the flexible coupling in a confined space.

One steering column assembly includes a jacket, a bearing, and a steering spindle rotatably supported by the bearing and at least partially extending inside the jacket. The spindle includes a hollow outer tube and a hollow inner tube. The outer tube has lengthening and attachment sections, and the attachment section has transition and connection portions. The lengthening section adjoins the attachment section at an end of the transition portion, and the transition portion is between the lengthening section and the connection portion. The lengthening section has first and second portions, with the second portion being between the first and transition portions, and the outer tube terminates at an end of the connection portion. The inner tube is press-fit into the outer tube, and an end of the inner tube is adjacent the transition portion end. The inner tube does not extend into either the attachment section or the first portion.

A press ring (1) for pressing tubular workpieces (35), comprising: at least two movable press jaws (3); and at least one connecting press jaw (5) connecting the movable press jaws (3); wherein the movable press jaws (3) are each hinged at their proximal ends to the connecting press jaw (5) by means of respective bolts (9), so that the distal ends (7) of the movable press jaws (3) can be rotated towards and away from each other to close respectively open the press ring (1) to receive a workpiece (35) therein, and characterized in that the respective bolts (9) are arranged in elongated holes (11), allowing a translational displacement of the bolts (9) in the elongated holes (11) upon rotating the movable press jaws (3).

A method comprises securing a first component of a lockable adjustment assembly to an end A of a first rigid tube via a first releasable coupling assembly. The method also comprises securing a second component of the lockable adjustment assembly to an end C of a second rigid tube via a second releasable coupling assembly. Further, the method comprises moving the first component and the second component, loosely coupled with each other, relative to each other with only three degrees of freedom to position the first rigid tube and the second rigid tube in a selected orientation with respect to each other. The method also comprises, with the first rigid tube and the second rigid tube in the selected orientation relative to each other, locking the lockable adjustment assembly so that the first component and the second component have zero degrees of freedom relative to each other.

A subsurface system includes a tubular having an opening. A filtration media is mounted about the tubular over the opening. The filtration media includes a selectively expandable outer surface positioned over the opening. The selectively expandable outer surface includes one or more selectively expandable openings. The one or more selectively expandable openings transition from a first dimension to a second dimension upon expansion of the selectively expandable outer surface.

A shoelace system for an article of footwear may include an elastic shoelace having a metal tip with a rounded-rectangle cross section. Corresponding eyelets of the footwear have a similarly shaped opening. In some examples, the shoelace tip is configured to pass through the opening of the eyelet in only one orientation. In some examples, manufacturing the shoelace includes inserting the lace into a hollow tip and then stamping the tip into the desired shape.

Electrically powered crimp tools are described. Also described are methods of operating the tools and methods of crimping. The tools include a housing, an electric motor, a roller screw assembly, and a jaw assembly. In particular versions of the tools the jaw assembly includes a cam linkage member that is manually displaced by a user to more easily open the jaws after performing a crimp.

A crimp tool includes a frame, a lead screw and a nut assembly connected to the lead screw. A spring member is connected to the frame and movable with rotation of the lead screw. A first transducer is connected to the nut assembly to measure a first force applied on the nut assembly. A second transducer is connected to the spring member to measure a second force applied thereon by the spring member.

A tapping sleeve includes a first bend line in a planar outlet band between a first side end and a second side end of the planar outlet band, the first bend line extending from a front end to a back end of the planar outlet band, a first outlet flange defined between the first side and the first bend line; a second bend line in the planar outlet band between the first bend line and the second side end, the second bend line extending from the front end to the back end of the planar outlet band, a second outlet flange defined between the second side and the second bend line; and an arcuate portion formed between the first bend line and the second bend line.
