The present invention relates to a work piece as well as to the use of this work piece in a method for the efficient cleaning of a cage. To this end, the work piece comprises a rectangular bar frame (1) and telescopic bar combinations (2) for mounting underneath a mounting frame (7) of the cage, enabling the cage to be lifted and forwardly tilted until a bottom placed on the mounting frame (7) along with the dirt on it falls out of the cage. To this end, the work piece is steered from the cabin of a lifting gear with which it is connected through means of clamps and a hydraulic connection.

A coalignment system including wedge-prism assembly that can be attached to a conventional night vision scope, for example. This could allow a standard handheld night vision scope to be deployed in different modes such as on headmounted goggles or as an augmentation scope in front of a day sight a weapon while enabling Line of sight/point of impact (LOS/POI) correction. In order to ensure maximum compatibility, the coalignment system includes diopter adjustment.

The present invention relates to a method for the manufacture of pressure-resistant gas and/or liquid tight containers made from thermoplastic materials. To this end the method comprises the following steps: providing a removable external mandrel around a neckpiece, followed by providing at the inside of such mandrel a thermoplastic material for the manufacture of a thermoplastic internal wall. Hereupon the external mandrel is removed and the thermoplastic internal wall is filled with a cooling liquid. Hereupon additional thermoplastic material is provided to the external side of the thermoplastic wall and is consolidated either during the provision hereof, or thereafter or both. Hereupon the cooling liquid is removed and the container is ready for being used.
