Abstract: An anti-theft lock assembly used in conjunction with ignition switches and locks which are operated by universal keys. The device can be attached to, and operate, the universal switch or lock by the use of non-universal key. Once the device is attached to the universal switch or lock the key to operate the device can be turned to the key lock position and then extracted, locking the device to the universal key switch or lock, therefore restricting the ability to operate the switch or lock with a universal key. The device can be easily removed by simply inserting the key into the device, rotating the key to the vertical position and removing the device, giving on the ability to operate the switch or lock with the universal key as normal. The device does not, however, need to be removed in order to operate the switch or lock. With the device attached, the switch or lock can be operated in the same manner as before using the key provided with the device to operate the switch or lock.

Abstract: A tensioning apparatus for a circulating element, such as a belt or a band, has a basic body in which a first chamber is formed. A piston is positioned in the first chamber and carries a piston rod. The piston can be displaced in the first chamber by the use of a pressure fluid. Either the piston rod or the base body is attached to the carrier for the belt or band. Either the piston rod or the basic body carries a head piece which can be moved in contact with the circulating element. A locking mechanism for the piston rod can be engaged and disengaged by the use of fluid pressure.

Abstract: A multi-layered printed product is cross cut and stapled by being fed past a gripping and folding blade cylinder and cooperating binding and cutting cylinders. The binding and cutting cylinders have parallel but offset axes of rotation and define envelopes of rotation which intersect each other at a point which is before, in the direction of travel of the printed product, the point at which the binding and cutting cylinders cooperate with the gripping and folding blade cylinder.
