Abstract:
According to one embodiment, a connector assembly for assembling at least two portions of a bicycle frame has first and second connectors, adapted to be mounted to the frame. The first connector has a body with an inner aperture, a peripheral region, a threaded exterior profile greater than a body outer profile and an axial contact surface. The second connector has a body with an exterior profile, a pilot to be received in the first connector inner aperture and a peripheral region having an exterior profile and an axial contact surface. A sleeve has a first region with an aperture to receive the second connector body exterior profile, a second region with an inner profile to receive the second connector peripheral region exterior profile, and a threaded region engaging the first connector threaded exterior profile for fastening the connector assembly and maintaining engagement of the pilot and axial contact surfaces.
Abstract:
A rod to rod connector includes a connector body containing a rod retaining insert. An interconnecting portion inner connects to a body to at least one other connector body. The insert is snap locked within the connector body simultaneously while retaining a rod within the insert in a locked condition.
Abstract:
A fusion stabilization chamber stabilizes the spine following removal of one or more vertebrae, and facilitates bone growth. The chamber includes two hollow members (1), (3), preferably having slightly trapezoidal cross sections, which slide relative to each other in a telescoping manner. The hollow members preferably have walls made of a metal mesh (5). Barrel vaults (7) attached to the hollow members form guides for screws (9) which can attach the chamber to the vertebrae adjacent the corpectomy site. Because of its adjustability, the chamber can fit a wide variety of corpectomy sites. One can fill the chamber with bone material, which can eventually fuse to the adjacent bone. A pair of stabilizing plates (13) prevents the surgeon from pushing the chamber too far towards the spinal cord. The chamber eliminates the need to maintain a large and costly inventory of screws, and neurosurgeons can learn to use it quickly and easily.
Abstract:
A medical tubing connector pair includes a female tubing connector, and a male tubing connector. The female tubing connector has an external thread and the male tubing connector has an internal thread, the external and internal threads threadingly engaged to secure the female and male tubing connectors together. The internal thread is made from a flexible material to permit the female and male tubing connectors to be connected to or disconnected from each other without rotation of the tubing connectors relative to each other.
Abstract:
Für den Einsatz im untertägigen Berg- und Tunnelbau ist ein Hydraulikstempel (1) vorgesehen, der vor allem im Schildausbau eingesetzt werden soll. Bei diesem Schildausbau bzw. bei dem Hydraulikstempel (1) werden das Außenrohr (15) mit dem Fußanschlussteil (16) und dem Handgriff (17) und das Innenrohr (19) mit der Kopfplatte (20) über Federstahldrahtanker (35) wirksam miteinander verbunden, die in entsprechenden Verbindungsnuten (36, 37, 38) bzw. (39, 40, 41) so angeordnet sind oder anzuordnen sind, dass im Übergangsbereich (42) so hohe Kräfte übertragen werden können, dass eine wirksame und bleibend wirksame Verbindung zwischen den Bauteilen gewährleistet ist. Bei rund (700) bar ist bei entsprechender Ausrüstung ein Setzdruck von (600) t zu verwirklichen, wobei vorteilhafterweise diese besondere Verbindungstechnik den Einsatz von hochfesten Rohren ermöglicht, was zu wesentlich dünnwandigeren Rohren führt.

Abstract:
A linearly adjustable device comprising a main body including at least two body sections each having a longitudinal axis, and a linear actuator. The sections are operatively connected together for linear movement relative to one another in the axial direction. The linear actuator is operatively mounted to the main body for causing the relative axial movement between the body section. The linear actuator includes a drive and a power transmission mechanism operatively connected to the drive. The transmission mechanism includes an elongated threaded member operatively connected to one of the body sections and a cooperating threaded member operatively connected to another of the body sections such that relative rotation between the elongated threaded member and the cooperating threaded member causes relative movement of the body sections.
Abstract:
A locking device interacting with a drive member and including an inner tube (1) and an outer tube (3); where the inner tube (1) has a first free end that projects from, and is axially displaceable from, a first end of the outer tube; where there is a locking member (4) on the other end of the inner tube (1), said locking member (4) providing the means whereby the inner tube (1) and the outer tube (3) can be releasably locked in various axial positions relative to each other; where the locking member (4) includes a tubular locking sleeve (9) that is slotted by at least one axially aligned slot (13) - said slot including a wedge-shaped cut-out (113) with essentially tangentially aligned wedge surfaces (16) - and a wedge (14) that includes wedge surfaces (15), said wedge surfaces being, when acted upon by a drive member (41) that includes a thread groove (42), displaceable along and relative to interacting wedge surfaces (16) of the locking sleeve (9), such displacement pressing the locking sleeve (9) against the outer tube, the inner tube (1) and the outer tube (3) being thereby axially locked relative to each other, said displacement occurring through the drive member (41) being rotated around an axis that is essentially parallel with the longitudinal axis of the inner tube (1), the thread groove (42) thereby interacting with a thread (35); and, where the rotation of the drive member (41) occurs via a torsion rod (7) when the torsion rod (7) is rotated, relative to the inner tube (1), around a longitudinal axis that is essentially parallel with the longitudinal axis of the inner tube (1).
Abstract:
The invention relates to a hydraulic ram (1) for use in underground mining and tunnel construction, in particular for shield tunnelling. In said shield tunnelling or in said hydraulic ram (1), the exterior pipe (15) is actively connected to the foot connection part (16) and the handle (17) and the interior pipe (19) is actively connected to the head plate (20) by means of spring steel wire ties (35) that are located or can be located in corresponding connecting grooves (36, 37, 38) and (39, 40, 41) in such a way that forces of an intensity which guarantees an active, permanent connection between the components can be transmitted in the transition area (42). A placing pressure of (600) t can be achieved at approximately (700) bar with the corresponding equipment. This special connection technology advantageously permits the use of high-tensile pipes which leads to the use of pipes with significantly thinner walls.
