Title: Apparatus for transporting articles as a luggage carrier
Inventor: NEUL JUERGEN
IPC: B62J9/40
Filed: 1988-09-20
Abstract: Luggage carriers are nowadays constructed as wire frames onto which articles are strapped and clipped. It is, however, not possible to accommodate relatively small articles such as an air pump, a raincoat or locks. By means of the container, luggage can be transported in the conventional manner, as can diverse small items which can also be integrated, in order to offer protection from the weather and to prevent scratching of the paint. The container is provided with round edges and corners and is not higher than air pumps, it being possible to configure the rear so that it is higher in order to have larger reflectors and more space for the items to be carried. The luggage-carrying surface is provided with a structure which is to limit sliding of the luggage. The luggage is held by means of a wire hoop or a rubber cord. The container can be closed by means of a clamping lock or a key lock. The container is supported with metal bars which are profiled or provided with wire nails, have a diameter of approximately 8 mm, are also embedded up to half way in the housing and are provided with a protective covering for better adhesion.

Patent DE-3901254-A1 (DE)
Inventor: JUNKER ERWIN
IPC: B23Q3/08
Filed: 1989-01-18
Abstract: A method and a device for clamping plane instable parts for subsequent machining are proposed. Here, the workpiece to be machined is secured radially and axially against the bearing surface of the clamping device and, after its radial centring on the surface remote from the surface to be machined, is supported at a multiplicity of locations over a minimum area or in a point-like manner. In this axially supported position of the workpiece, a tensile force is applied in the direction of the clamping device in order to fix the workpiece at at least one surface section of small area. The clamping device has axially movable bolts and devices acting over a small area for applying tensile force to the surface remote from the workpiece surface to be machined. During the machining of the workpiece, the bolts, each covered by the workpiece, are placed against the surface for the purpose of support and are fixed in this positive-locking position, while a tension means for axially fixing the workpiece is in engagement with the latter. <IMAGE>

Title: Theft-proof attachment device for a wheel
Inventor: BOCK ANDREAS
IPC: F16B37/14
Filed: 1989-02-15
Abstract: In known theft-proof attachment devices for wheels, the removal of cover caps arranged on the attachment screws is only possible with a considerable expenditure of force and with the use of for example screwdrivers or pliers. Additionally, there is a considerable risk of injury and damage. The new attachment device is intended to permit the fitting and removal of the cover cap to be carried out easily and quickly. For this purpose, engagement faces (18) which can be engaged with a commercially available tool are provided on the cover cap (6). When the cover cap (6) is rotated, both knob-shaped elevations (9, 10) and (11) formed on the end side of the head (8) of the screw and knob-shaped elevations (12, 13 and 14) formed correspondingly on the cover cap (6) cause the cover cap (6) to be lifted off. The anti-theft attachment device for a wheel is particularly suitable for wheel discs (2) which have deep holes (4) for receiving the attachment screws (7). <IMAGE>

Title: Running thread cutting system - has clamping and cutting plate accelerated towards thread and abutment for the cutting action
Inventor: GINSBERG HANS-JUERGEN
IPC: B65H54/71
Filed: 1989-12-14
Abstract: A running thread is cut by passing it through a casing with a tiltable clamping and cutting plate which is kept clear of the thread and of an abutment by a power cylinder. This plate carries a weight and if the power cylinder rod is retracted, the clamping/cutting plate is accelerated by the weight and its cutting edge squeezes the thread on the abutment to cut it.
