Abstract: Deformable spacers and spacer assemblies absorb energy when flange bolts are subjected to compressive axial loads by plastically deforming, failing in shear, rupturing or in a combination of failure modes so the flange bolts and the flanges connected thereby are not damaged. One deformable spacer may have a hollow cylindrical body with a plurality of elongated slots there through. Another deformable spacer may have an annular stiffener extending inwardly from an inner surface of a hollow cylindrical body. A spacer assembly may include an inner cylindrical body, and outer cylindrical body, and an annular shoulder extending from one of the bodies and engaged by the other body shears when a shear failure load is applied to the flange bolt. Another spacer assembly may include an annular belt around a cylindrical body so that the belt will rupture before the cylindrical body plastically deforms.

Abstract: A blind fastener has a sleeve and a pin. The sleeve has a shank with a shank bore and a head with a head bore smaller than the shank bore. The pin has a pin installation portion with a proximal end portion and a distal end portion. The pin also has a breakaway portion with a pin grip, and a pin break groove between the installation portion and the breakaway portion. The pin further has a grip portion at the proximal end portion of the pin installation portion and directly adjacent to the pin break groove. In a pre-installation configuration, the grip portion is in the sleeve bore. In an installation configuration, the grip portion is in the head bore and forms a friction fit with the head bore to prevent the installed sleeve from inadvertently coming free of the installed pin.

Abstract: A hollow wall anchor includes a wall penetrating component having an externally threaded portion and a wall penetrating end portion, and a body component having a wall face engaging portion and an internally threaded portion that receives the externally threaded portion of the wall penetrating component. Rotation of the components together in a first direction for wall penetration moves both the wall penetrating component and the body component into the wall until the wall face engaging portion of the body component engages the wall to limit further rotation of the body component while the wall penetrating component continues to rotate such that interacting threads of the two components pull the wall penetrating component further into the body component. As the wall penetrating component is pulled further into the body component one or more retention arms are expanded outwardly behind a rear surface of the wall.

Abstract: Fastener embodiments of the invention comprise a freely translatable collet body, which at least partially translates within an auxiliary structure, and further comprise a captive threaded screw for rotationally engaging with the collet body to transform rotational movement into translational movement through substantial arresting of collet body rotation by way of an anti-rotation means. The screw comprises a free-spin feature that functionally, but not physically, decouples a drive tool from the collet body.

Abstract: The invention relates to a device for preventing spills from inside mining mills, said device maintaining a seal around bolts used to secure mill liners, such that the bolt remains under tension within a range of several millimetres along the length between the head and the nut of the bolt, with the length covered by the elements compressed between the head of the bolt and the device for preventing pulp leaks in mills, exerting pressure on the washer that provides a seal against leaks from inside the mill. The device comprises one or more pairs of Belleville washers which include an annular space into which a sleeve with an inner seal is inserted. Said sleeve includes a flange of larger diameter to allow the action of the bolt on the Belleville washers, said Belleville washers exerting pressure on the washer that provides a seal against leaks from inside the mill.

Abstract: Intermittent screw thread geometry with a rapid step-wise lead feature when external threads are engaged with internal threads of reflective geometry. In an embodiment, thread segments are alternated with unthreaded segments of equal arc length along a helical path of a single-start thread form which results in an odd number of alternating thread/gap features along the helical path per revolution of the thread body. When such external intermittent threads engage internal intermittent threads of reflective geometry, an external thread body can be axially advanced or retracted through an internal thread body in a rapid step-wise fashion by turning the external thread body in either the clockwise or counterclockwise direction, or in both directions alternately, with respect to the internal thread body when a net axial force is applied to the external threaded body with respect to the internal thread body in the desired linear direction of travel.

Abstract: A drive system with full surface drive contact. The drive system tends to maximize the surface contact pattern or area at typical bit-recess reaction (drive) torque values, thereby tending to minimize bit-recess surface contact stresses, coating damage, recess ream and premature bit fatigue failure. The drive system comprises a fastener and/or bit having drive surfaces formed of either polygon involutes or a single arc construction. A punch is also provided for forming a recess in either the fastener or the bit, wherein the punch has corresponding surfaces.

Abstract: A fastener for attaching together layers of a substrate. The fastener includes a slide body, a bolt, a conical spring, and a toggle having a pivot coupled with one end of the slide body. The conical spring is disposed over a shaft of the bolt and the shaft is engaged within the slide body. The slide body and toggle are inserted into an aperture through the layers of substrate in a first configuration until the conical spring contacts a front face of the layers of substrate. Compression of the conical spring against the front face advances the toggle a clearance length out of the aperture on a back face of the layers of a substrate such that the toggle can switch to a second configuration that prevents retraction through the aperture. Extension of the conical spring automatically engages the toggle with the back face of the substrate to prevent rotation of the slide body within the aperture.
