A removable device for attaching two mechanical parts includes a pin removably locking a first part with respect to a second part, a retainer member on the pin and a resiliently loaded tension member which collaborate to prevent the pin from coming out of its locked position; the removable device further includes at least two inclined surfaces, the general shape of which is that of a projection oriented in the axial direction of the pin, such that when the pin rotates, the retainer member runs along the inclined surfaces and the pin moves between the locked position and unlocked position against a force exerted on the pin along a longitudinal axial direction of the pin exerted by the tension member.

A vehicle drive system comprises a first shaft and a second shaft that includes an opening configured to receive the first shaft. A shaft retention apparatus comprises a support component extending axially and along the outer contour of the outer surface of the first shaft and the outer surface of the second shaft, to bridge the two shafts at an intersection thereof. A first clip portion extends from the support component and engages a groove in the outer surface of first shaft and a second axially spaced clip portion extends from the support component and engages a groove in the outer surface of the second shaft, preventing prevent axial movement therebetween.

A system and method for a quick release of a second object from a first object, e.g., quick release of hurricane panels (second object) from the inside of a habitable structure (first object). A stepped quick release bolt assembly or a dual quick release car assembly may be employed. In the preferred embodiment, a pin passing through a cross bored hole in a stepped bolt disposed in a receiving structure attached to a first object is releasable in order to disconnect the second object from the first object.

A flame holder system includes a modified torch body and a ceramic flame holder. Catch pin(s) are coupled to and extend radially out from the torch body. The ceramic flame holder has groove(s) formed in its inner wall that correspond in number and positioning to the catch pin(s). Each groove starts at one end of the flame holder and is can be shaped to define at least two 90 elbows. Each groove is sized to receive one catch pin therein when the flame holder is fitted over the end of the torch body. The flame holder is then manipulated until the catch pin(s) butt up against the end of the groove(s).

An overload protection device for cable lines, and in particular in cranes, is provided, having at least one electronic overload safety means. The overload protection device is provided to prevent any kind of damage which can be caused by an overload. That is achieved by providing a mechanical or magnetic overload protection device (1) in addition to the electronic overload safety means. The overload protection device (1) is integrated into the cable line or arranged at the cable fixing point and responds when a permissible cable tension force is exceeded and implements a cable extension.

A method of assembling a bearing assembly includes fitting a first ring onto a first end of a gear shaft. A second ring is fed into a slot in the first ring. The second ring is driven through the slot in the first ring. The second ring is positioned within the first ring. The second ring is positioned about the gear shaft such that a first end and a second end of the second ring are covered by a solid portion of the first ring.

A fastening device for fastening an element in a keyhole-shaped cutout in a wall includes a retaining element which in the fastened state of the fastening device is configured to rest against a front side of the wall, and to at least partially cover an edge of a narrower opening of the keyhole-shaped cutout. The fastening device also has a locking element which in the fastened state of the fastening device is configured to engage through a wider opening of the keyhole-shaped cutout, and to retain the fastening device from a back side of the wall.
