Title: Method and circuit arrangement for identifying and testing the genuineness of all kinds of specific features
Inventor: BETH THOMAS PROF
IPC: G07C9/00
Filed: 1988-05-21
Abstract: The invention concerns a method and circuit arrangement for identifying and testing the genuineness of system access authorisation. Known methods, which use, for instance, magnetic cards or passwords as "signatures", either require a very large hardware cost, or the processing speed is slow, or they are more or less open for illegal users. The invention uses the so-called zero knowledge proof technique, i.e. the system knows a large amount of personal or system-related data, and when access to the system is desired, it checks a randomly selected sequence of this data. By using the method according to the invention, the cost of the hardware which is required for technical implementation of the zero knowledge proof technique is greatly reduced, and access security, processing speed and user-friendliness are considerably increased. All kinds of system access authorisation (computer systems, cash machines, buildings).

Patent DE-3832182-A1 (DE)
Title: Friction clutch with a locking device for the disengaged position
Inventor: WEIDINGER REINHOLD DIPL ING
IPC: F16D13/71
Filed: 1988-09-22
Abstract: The invention relates to a locking device for the power take-off clutch of a double clutch. To relieve the release system of load in the disengaged condition of the power take-off clutch, the proposal is to provide anti-buckle support elements in the form of swivel pins which, in the disengaged condition, hold the pressure plate at a distance counter to the force of the clutch main spring. The release system is thus essentially relieved of load and the disengaged condition has no effect on the durability of the release system, even over a relatively long period of time. For engagement, the anti-buckle support elements are pivoted inwards in the direction of engagement and moved out of engagement by a small force from the release system.

Title: Axially clampable locking bar to secure loads in packaging compartments, such as containers
Inventor: BERNS HARALD DIPL ING
IPC: B60P7/15
Filed: 1989-01-19
Abstract: In a locking bar, two tubes are provided which can be joined together telescopically and are held in a desired extended position by means of a holding member by a clamping lever which can be pivoted on the outer tube. In order to develop a cost-effective locking mechanism which is convenient to operate and allows infinitely variable adjustment, it is proposed to provide, as the holding member, a clamping ring which acts on the inner tube, is loaded by axial force on one side in the locking position, and is effective in a clamping manner by tilting. At the same time, the two tubes, joined together, are inhibited in axial movement relative to one another by a braking member. In an extreme pivoted-out position of the clamping lever, however, the clamping ring butts against an end stop of the outer tube, as a result of which it is moved back into a radial plane and the clamping is eliminated.

Patent DE-3921591-A1 (DE)
Inventor: SCHMIDT FRITZ J
IPC: B09B3/00
Filed: 1989-06-30
Abstract: A process for removing volatile contaminants, in particular low-boiling and/or steam-volatile organic compounds from soils and comparable materials, especially those of which large proportions are in a bound/clayey form, by extraction and purification of the extracted gas contaminated with the materials to be removed is to be made more effective and economical. For this purpose, the material to be purified is introduced into a closed chamber in which a quasi-inert gas is introduced into the interior of this material and extracted again from the closed chamber after flowing through the material, purified and re-introduced to this chamber in circulation until the desired degree of purity of the material to be processed is reached. As the closed chamber, a transportable steel container can be used as one version, in which the contaminated soil material is aerated in removable grid boxes. In further versions, the treatment of the material is carried out continuously in gas-flooded screw conveyors or belt filters. <IMAGE>

Patent DE-4020776-A1 (DE)
Inventor: MEIXNER HANS-WERNER
IPC: B26B7/00
Filed: 1990-06-29
Abstract: Described is a device for driving a tool in the longitudinal direction to carry out an oscillatory back-and-forth motion, the tool working with high efficiency at high oscillation frequencies and being usable as an easy-to-handle hand tool since, as a result of the drive design, the weight-to-exerted-force and volume-to-exerted-force of the driven tool can be made particularly low. This drive comprises a reciprocating piston (8) which feeds oil to a work piston (22) and causes the work piston to reciprocate against the pressure of a spring (25) acting on the work piston (22) and against the pressure of the atmosphere. The tool to be driven is preferably connected to the work cylinder (22) by means of the couterpressure spring (25). The work cylinder (20) and feed cylinder (9) are connected to each other by a flexible hose line (14) so that their weight does not act on the hand tool.
